The structure of economic modeling of the potential impacts of climate change: Grafting gross underestimation of risk onto already narrow science models

Nicholas Stern (London School of Economics and Political Science, London, U.K.)

Abstract


Scientists describe the scale of the risks from unmanaged climate change as potentially immense. However, the scientific models, because they omit key factors that are hard to capture precisely, appear to substantially underestimate these risks. Many economic models add further gross underassessment of risk because the assumptions built into the economic modeling on growth, damages and risks, come close to assuming directly that the impacts and costs will be modest and close to excluding the possibility of catastrophic outcomes. A new generation of models is needed in all three of climate science, impact and economics with a still stronger focus on lives and livelihoods, including the risks of large-scale migration and conflicts.

Skeptic scientist Richard Tol claims benefits to climate change (citing only his own work), as newly issued IPCC report outlines climate risks

from Climate Science Watch, March 29, 2014
 
As hundreds of scientists work to come to consensus on a summary of global climate change impacts and vulnerabilities, an outlier scientist has sought a larger spotlight for his fringe views. The Working Group II (WGII) report of the Intergovernmental Panel on Climate Change (IPCC), to be released in Japan tomorrow, highlights the grave risks we face as the climate changes. But some news coverage previewing the release has focused on the views of Dr. Richard Tol, an IPCC author who opted to withdraw [six months ago] from the author team drafting the report summary (known as the Summary for Policy Makers) due to what he claimed were the "alarmist" nature of early drafts. In fact, the summary is a very conservative portrayal of the state of climate science understanding.
 
-       Tol's extreme outlier views underscore the IPCC's role as a consensus document, attempting to bring in as many diverse viewpoints as possible. That includes those such as Tol with connections to climate skeptic groups. Tol may have been dissatisfied with this process, but he had the same opportunity as any scientist.
-       The report ultimately reflects the fact that Tol's work is outside the mainstream. According to a leaked copy of the current draft, the report finds that the impacts of climate change are and will continue to be negative. It doesn't "conceal" the benefits of climate change in localized areas, but it makes it clear that the balance of impacts is harmful overall. The report also shows there are limits to our potential for adaptation.
-       The report shows how important it is to begin reducing emissions immediately. We've already caused some warming, and there's more on the way. Our choice now is to reduce emissions and experience the impacts of moderate warming, or delay and experience extreme warming. Voices such as Tol that promote the "benefits" of warming are presenting a false choice.
 
Impacts of warming are negative, both for agriculture and GDP.
The WG2 draft report is clear that agricultural impacts of climate change are negative (SPM p.3 line 15). The report doesn't hide the fact that some areas will experience positive agricultural impacts, but it concludes that negative impacts will outweigh positive impacts on a global scale, now and into the future. A recent lit review backs up this claim, reviewing negative impacts on yield for warming of 2ºC. The report also concludes that crop markets are sensitive to climate extremes, judging by recent spikes in food prices following extreme events in key producer countries (SPM p.3 line 15).
 
In interviews Tol has dismissed this finding, saying, "They will adapt. Farmers aren't stupid." But the report is also clear that adaptation carries costs and limits. For example, as warming approaches 4ºC, even the best adaptations will not be able to avoid serious threats to food security (WG2 SPM p.10 line 19). And this is occurring in a world where global demand for food is expected to increase.
 
With respect to global GDP, the WG2 report only offers cost estimates up to 2.5ºC of warming. These impacts are negative, costing up to 2% of global income, which is acknowledged to be only a partial estimate. In fact, the costs of 2.5ºC of warming laid out in WG2 are something of a best-case scenario (or at least a reasonably good scenario) showing what will happen IF we take strong action to reduce carbon emissions. If we do not take action on climate mitigation, we could be experiencing around 4ºC of warming by 2100 according to the business as usual (RCP 8.5) scenario (WGI Annex II Table 7.5). That's uncharted territory and possible within the lifetime of those alive today.
 
Other estimates suggest the high impacts on global GDP with warming of 4ºC (For example the Stern Review found impacts of 5-20% of global GDP). GDP also does not fully account for humanitarian disasters to poorer countries. Extreme impacts in poor, tropical areas (which are expected to be the first to experience the most severe disasters) may not significantly affect global GDP – but they still matter. Reports like the World Bank's Turn Down the Heatportray the consequences.
 
Discussing benefits of warming presents a false choice.
Furthermore, even Tol acknowledges that warming will be detrimental at high levels, which is where we're headed without climate mitigation. In fact, we may already be committed to half of the 3ºC of "moderate" warming that Tol believes will be beneficial. This means that our choice is between reducing emissions in order to experience moderate (rather than severe) warming, or doing nothing and experiencing severe warming, beyond 4ºC. As Tol wrote in a 2009 paper: "The climate responds rather slowly to changes in greenhouse gas emissions. The initial warming can no longer be avoided; it should be viewed as a sunk benefit." Some are spinning Tol's work to present a false choice between no warming and moderate warming, but this isn't really an option available to us. Action now is advisable under any plausible climate scenario: the risks are simply too high to wait.
 
The WGII summary is a consensus product with many voices.
The IPCC included Tol as an author, despite his connections to the Global Warming Policy Foundation, which has repeatedly attacked the IPCC, refused to disclose its funding sources, and promoted questionable science. But the report is a consensus document, and if the literature does not support a viewpoint, it won't be emphasized. As Bob Ward, policy and communications director of the Grantham Research Unit on Climate Change and the Environment at the London School of Economics, told Reuters: "Of the 19 studies he surveyed only one shows net positive benefits from warming. And it's the one he wrote." As a coordinating lead author of the underlying chapter on economic impacts, Tol himself ended up detailing the negative net impacts of climate change. Yet, he is contesting a summary of the whole report that is consistent with the findings of his chapter. The real consensus shows that climate change is serious and detrimental, and we need to act now to stop it.​

The View from Europe: America’s Shale Boom Looks More Like a Blip

by Sharon Kelly, DeSmogBlog, March 4, 2014

The fracking boom has progressed at breakneck speed across the U.S., with roughly one in 20 Americans now living within a mile of a well drilled since 2000.
So, how much has the economy benefited from this drilling surge?
Not much, according to a report presented to the European Union Parliament last month, which found “no evidence that shale gas is driving an overall manufacturing renaissance in the US.”
The shale boom’s economic contributions are very narrow, inflating local economies in places where drilling is intense but generating little impact on the country’s overall economic growth, the Institute for Sustainable Development and International Relations, a French think tank, concluded.
Although natural gas prices have fallen from their highs in 2008, benefiting consumers, those low levels are unlikely to be sustained and the U.S. is still expected to remain heavily reliant on importing crude oil, the researchers found.
Even using very optimistic assumptions, the report said, the industry’s cumulative long term effect on America’s Gross Domestic Product (GDP) will be less than one percent. “Despite very low and ultimately unsustainable short-term prices of natural gas, the unconventional oil and gas revolution has had a minimal impact on the US macro-economy.”
That’s not the amount that shale gas will add to the economy each year, the researchers said. Instead, the industry will make up no more than 0.84% of total GDP between 2012 and 2035 – the years when the shale boom is projected to be at its height. To put that in context, the personal care products industry – hair styling, cosmetics and the like – contributed 1.4% of GDP in 2010 – nearly double the impact that the EU report found the shale gas rush could have.
Although shale gas promoters have promised a rebirth of American manufacturing thanks to the drilling frenzy, the European analysts found that the benefits have mostly been felt by a small slice of the chemical industry, the petrochemicals industry.
The analysis also threw cold water on the idea that natural gas will help decrease America’s carbon dioxide emissions or help combat climate change. “Absent further policies, the US shale revolution will not lead to a significant, sustained decarbonisation of the US energy mix nor will it assure US energy security,” the researchers wrote.

Although projections showed that policy change could potentially drive a shift from coal to natural gas, such a plan also “locks the U.S. in” to a carbon-intensive infrastructure. And if current policies remain in place, emissions will be “stagnant at current levels out to 2040, clearly insufficient for a reasonable US contribution to global climate change mitigation.”
The costs of the drilling boom have been well documented. State regulators have struggled to keep pace with the oil and gas industry, and the country is now dotted with sites where land or water were contaminated by spills and other accidents, where gas wells, trains or pipelines have exploded, or where locals say air and water pollution has left them with a range of health problems.

Even the CEO of ExxonMobil, Rex Tillerson, has objected to the industry’s arrival in his own neighborhood, citing traffic jams and harm to property values.
But the new and woefully under-reported European study undermines the two major upshots that proponents of drilling have put forward — economic gains and a lower carbon footprint.
The European report only focuses on one greenhouse gas, carbon dioxide, and does not touch on the impacts of a second, more potent greenhouse gas: methane.

Although natural gas produces carbon dioxide when it burns (about 50
60% as much as coal), scientists have warned that the harm to the climate done when unburned natural gas, which is primarily methane, leaks out into the atmosphere could decimate climate benefits from switching away from other fossil fuels and burning natural gas instead — especially when the effects that will be felt within our lifetimes are concerned, since methane’s global warming effects are at their strongest during the first few decades after it leaks to the atmosphere.
The shale boom’s marginal economic benefits come as little surprise to some analysts. “[D]ue to the size of the US economy, it has always been unrealistic to expect shale gas to move the needle much,” said Bill Powers, energy investor, analyst, and author of the book Cold, Hungry and in the Dark. “Since so much of our economy is service-related, tech, finance, healthcare and education, I have always been very skeptical of the claims of large economic impact.”
There are profound policy implications if the shale gas rush can generate only small economic benefits. The hope that the fuel could help bring back factory jobs to the U.S. has fed the Obama administration’s support for the shale gas rush. 
“Businesses plan to invest almost a hundred billion dollars in new factories that use natural gas,” President Obama said in his State of the Union address as he praised shale’s contributions to the economy.
But researchers from the International Monetary Fund say that chemical company investment plans have less to do with the shale gas rush, and more to do with a bounce-back from the 2008 market crash, dropping currency exchange rates, and the downwards pressure on American wages. “You had so much slack in the labor market in the recession,” Prakash Loungoni, head of commodities research at the IMF told National Geographic. “Work wage demands are pretty moderate in the [United States].”
In other words, even if shale gas does help bring back some manufacturing jobs, don’t expect those jobs to be high-paying.
Shale industry supporters often cite the sheer number of jobs created by the boom. But the estimates that politicians cite often turn out to be overblown. Pennsylvania Governor Tom Corbett recently found himself in hot water for his claim that drilling has created 200,000 jobs in his state. A recent analysis found that only 30,000 jobs could be directly linked to his state’s Marcellus shale rush, and that despite Corbett’s drill-baby-drill policies, job growth from Marcellus development has fallen roughly a third between 2010 and 2013.
The amount of jobs created by the gas boom has been grossly overstated,” explained Mr. Powers.
The impacts are even less striking when the ripple effects from drilling are taken into account. “[E]very gas-related job that was created in Texas, Louisiana and Pennsylvania and other states has probably resulted in a coal-related job that has been lost,” Mr. Powers added. “More importantly, the shale gas boom has greatly hampered job growth in the renewable sector.”
Prospects for shale gas in the European Union look even bleaker, the European researchers concluded.
The researchers honed in on the uncertainty surrounding exactly how much shale gas lays beneath European countries, noting that the continent has seen little drilling compared to North America, and so oil and gas companies know relatively little about Europe’s shale formations.
Using middle-of-the-road assumptions, the researchers concluded that shale gas could potentially supply between 3% and 10% of Europe’s natural gas, meaning that the continent would still be heavily dependent on imports.
This means that shale gas will be no panacea for Europe. “To solve its energy, climate and manufacturing competitiveness challenges, the EU thus needs a broad strategy of energy efficiency, innovation, low carbon energy sources, and a stronger internal market.”
That may prove to be a much more reliable plan than staking the future on shale gas, whose promised benefits increasingly seem like mostly smoke and mirrors.

Reuters' climate coverage drops 50% after "skeptic" Paul Ingrassia becomes Managing Editor, creating "climate of fear" in newsroom


by Denise Robbins, Media Matters for America, February 26, 2014

Reuters' climate coverage has continued to drop significantly under the regime of its new "skeptic" editor, with less than half the amount of climate coverage compared to before the editor took over, according to a Media Matters study. This finding comes despite two major reports on climate science that occurred during this period, suggesting that the paper's "climate of fear" may have persisted.

Former Reporter: "Skeptic" Editor Ingrassia Created A "Climate Of Fear" In The Newsroom. In July 2013, former Reuters Asia climate change correspondent David Fogarty revealed that when Paul Ingrassia --  a self-identified "climate change sceptic" -- took over as deputy editor-in-chief, a"climate of fear" surrounding climate change coverage followed. From Fogarty's blog at the Reuters-centered website The Baron:
From very early in 2012, I was repeatedly told that climate and environment stories were no longer a top priority for Reuters and I was asked to look at other areas. Being stubborn, and passionate about my climate change beat, I largely ignored the directive.
It was a strange repositioning of editorial focus for Asia, which has some of the world's top polluters and some of the greatest environmental challenges taxing economies and governments.

In April last year, Paul Ingrassia (then deputy editor-in-chief) and I met and had a chat at a company function. He told me he was a climate change sceptic. Not a rabid sceptic, just someone who wanted to see more evidence mankind was changing the global climate.

Progressively, getting any climate change-themed story published got harder. It was a lottery. Some desk editors happily subbed and pushed the button. Others agonised and asked a million questions. Debate on some story ideas generated endless bureaucracy by editors frightened to take a decision, reflecting a different type of climate within Reuters -- the climate of fear.

By mid-October, I was informed that climate change just wasn't a big story for the present, but that it would be if there was a significant shift in global policy, such as the US introducing an emissions cap-and-trade system.

Very soon after that conversation I was told my climate change role was abolished. I was asked to take over the regional shipping role and that I had less than a week to decide.

I decided it was time to leave.

By far one of the most bizarre climate e-mail exchanges occurred on 30 October regarding Hurricane Sandy. I offered to kick-off a story from Asia leading on the storm's impact on public opinion on climate change, given it occurred a week before presidential elections and was the type of storm climate scientists say we should expect as the planet warms. There was a huge amount of commentary to draw on from other media and commentators.

A senior Top News editor in Asia shot down the idea saying "climate change is one of those topics that can get people's backs up." Michael Stott, the Europe, Middle East and Africa regional editor in London, in turn, shot down that editor's view and urged the story to be written, saying: "Many other media will follow this trail -- it's an obvious angle and one we should explore."

Reuters in the US did the story, about 48 hours later than everyone else, despite reporters there itching to get a story out sooner.

Since I've left, I've lost count of the number of people who have asked me why Reuters' climate change coverage has changed in tone and fallen in volume. [The Baron, 7/15/13]

Since Ingrassia's Promotion To Managing Editor, Reuters' Climate Coverage Has Decreased Further. Media Matters analysis released on July 23, 2013, supported Fogarty's suspicions, finding that Reuters reported on climate change almost twice as much before Ingrassia became deputy editor-in-chief. Since Ingrassia became managing editor in February 2013, Reuters' climate coverage has only worsened, according to an analysis of the six-month period following our initial study. From July 24, 2013, to January 24, 2014, Reuters published 221 articles and 103 mentions about climate change, for a total of 324 stories. This is an 8% drop from 353 stories during an equivalent time period under the "pre-skeptic" editor's regime (which saw 353 total stories), and a more than 50% decrease from an equivalent time period before Ingrassia took over (675 total stories).

Reuters Climate Change Coverage
Just under half of Reuters' coverage (44%) was focused on policy -- a decrease from our previous study (63%) -- and coverage focused on science increased slightly from 12% to 14%. The articles quoted primarily politicians and government officials (45 percent of the time) -- similar to the previous study (41%) -- but their usage of scientists increased slightly to 19% of the time from 12% [Media Matters7/23/13] [University of Wisconsin-Madison, 2/4/13].

Reuters Still Uses False Balance On Occasion

CJR: Reuters Reporters Felt Pressure To Provide False Balance.  The Columbia Journalism Review reported that several Reuters reporters "felt pressure from management to add 'balance' to climate change stories by including the views of global-warming skeptics":
It's worth noting that most newsrooms around the country have reduced coverage of climate change-related issues since 2010. In 2011, Environment & Energy Publishing, which produces Greenwire, ClimateWire, and four other news services, estimated they reduced climate coverage by about 13%. According to an assessment published by The Daily Climate, The New York Times cut its global warming article count by 15%, and The Guardian slashed coverage by 21% that same year. (Reuters, too, dropped its climate coverage by 27% in 2011, before Ingrassia came aboard.)
But rumblings in the Reuters newsroom signal that the most recent dip in climate coverage is accompanied by a shift in editorial angle. I spoke on background to several journalists working at Reuters, who said that since Ingrassia was hired, they've felt pressure from management to add "balance" to climate change stories by including the views of global-warming skeptics. "I'm really glad someone outside the company is looking into this," said one staffer who did not wish to be identified. "I think this is the most worrying thing any of us have seen here" [Columbia Journalism Review, 7/26/13].
  • Reuters Articles Have Added "Skeptic" Modifiers On Whether Climate Change Is Manmade. On February 16, 2014, for instance, Reuters published an article on John Kerry's comments calling man-made climate change "perhaps the world's most fearsome weapon of mass destruction." Reporter Mohammed added a qualifying "skeptic" statement, that global warming might be "due to natural variability or other non-human factors":
The global scientists of the Intergovernmental Panel on Climate Change have said it is at least 95% probable that human activities, led by the burning of fossil fuels, are the dominant cause of global warming since the 1950s.
However, some skeptics argue that a rise in global temperatures is due to natural variability or other non-human factors.
The fact that temperatures have risen more slowly in the past 15 years despite a continued rise in greenhouse gas emissions has also emboldened those who question the need for urgent action [Reuters, 2/16/14].
Reuters' Decline In Coverage Came Despite Major IPCC Report. On September 27, 2013, the United Nations' Intergovernmental Panel on Climate Change (IPCC) released its Fifth Assessment Report (AR5) on the state of climate science, finding that humans are the "dominant cause" of "unequivocal" climate change, with the same certainty that cigarettes can kill. The IPCC releases Assessment Reports once every 5 to 7 years, yet even in including coverage of this major report, Reuters' climate coverage continued to decline. A Media Matters analysis of the report's media coverage found that Reuters mentioned the alleged "slowdown" in global warming in 42% of its stories, a misleading factoid that has been been wrongly seized on by "skeptics" to cast doubt on global warming. And the news agency helped provide widespread attention to prominent "skeptic" Bjorn Lomborg [Media Matters, 10/10/13].

CJR: Reuters Gave "Ambivalent" Coverage To "New Normal" Of Climate Change. The American Meteorological Society released their "State of the Climate" report in August, detailing a "new climate 'normal' " in 2012. The Columbia Journalism Review reported that the findings received "surprisingly limited analysis" given "the importance of the information," including Reuters, which just provided a "short summary" that included a "skeptical insertion": 
On Tuesday, the American Meteorological Society released its annual "State of the Climate" report, a hefty, 258-page document chronicling changes in global warming data. Compiled by members of the National Oceanic and Atmospheric Administration, along with 384 scientists from 52 countries, the report is used to set and influence domestic climate policy and distributes statistics that form the baseline for discussions of climate change.
This year's report holds a wide roster of data -- ranging from interesting to doomsday -- and most major newspapers and wire serves at least ran something based on the report press release. But considering the importance, and acute detail, of the information contained in the release, the mainstream press provided a surprisingly limited amount of analysis.
Reuters filed a short summary, "Signs of new climate 'normal' apparent in hot 2012 report," culling information entirely from NOAA's press release, with one skeptical insertion framing the slowing surface temperature rise: "The decrease in temperatures has been noted by climate-change skeptics who question the impact of human activities."

Peter Sinclair: Antarctic Ice Loss Accelerating (also Greenland)

by Peter Sinclair, Climate Denial Crock of the Week, March 29, 2014


Above, NASA video discussing increased mass loss from Pine Island Glacier, the soft underbelly of the West Antarctic ice sheet.

More evidence that the Antarctic Sheet is waking up.
WASHINGTON, D.C. — Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research.
The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, scientists report this month in Geophysical Research Letters, a journal of the American Geophysical Union. Pine Island Glacier, the most active of the studied glaciers, has accelerated by 75% in 40 years, according to the paper. Thwaites Glacier, the widest glacier, started to accelerate in 2006, following a decade of stability.
Here, video from December with several scientist’s views on accelerating ice sheets, and what the Earth’s history says about ice.

 

The study is the first to look at the ice coming off the six most active West Antarctic glaciers over such an extended time period, said Jeremie Mouginot, a glaciologist at University of California-Irvine (UC-Irvine) who co-authored the paper. Almost 10% of the world’s sea-level rise per year comes from just these six glaciers, he said.

“What we found was a sustained increase in ice discharge—which has a significant impact on sea level rise,” he said.
The researchers studied the Pine Island, Thwaites, Haynes, Smith, Pope and Kohler glaciers, all of which discharge ice into a vast bay known as the Amundsen Sea Embayment in West Antarctica.

Below left, A satellite image of Pine Island Glacier shows an 18-mile-long crack across the glacier. 

Researchers used cracks and other physical features on the glaciers to calculate glacier acceleration by comparing image data from year to year to see how far the cracks traveled.

pineislandcrackAmerican Geophysical Union continued:
The amount of ice released by these six glaciers each year is comparable to the amount of ice draining from the entire Greenland Ice Sheet annually, Mouginot said. If melted completely, the glaciers’ disappearance would raise sea levels another 1.2 meters (four feet), according to co-author and UC-Irvine Professor Eric Rignot.
The decades of increasing speeds and ice loss are “a strong indication of a major, long-term leakage of ice into the ocean from that sector of Antarctica,” noted Rignot.
“This region is considered the potential leak point for Antarctica because of the low seabed. The only thing holding it in is the ice shelf,” said Robert Thomas, a glaciologist at the NASA Wallops Flight Facility, in Wallops Island, Va., who was not involved in the study. Ice shelves are platforms of permanent floating ice that form where glaciers meet the sea. In West Antarctica, ice shelves prevent the glaciers investigated in the study from slipping more rapidly into the ocean.
Mouginot and his colleagues used satellite data to look at sequential images of the glaciers from 1973 to 2013. The scientists then calculated how fast the ice was moving by tracking surface features, such as cracks in the ice, to determine the distance the glaciers traveled from month to month and year to year.
While the study considered the six glaciers collectively, it also revealed unprecedented change on the individual glacier level. Thwaites Glacier, the largest of the six with a width of 120 kilometers (75 miles), experienced a decade of near-stability until 2006, when its speed picked up by 0.8 kilometers (half a mile) per year – a 33 percent increase in speed, according to the study. This is the first time that such changes on Thwaites Glacier have been observed, said Mouginot.
Of all the glaciers in the study, Pine Island Glacier accelerated the most since 1973, increasing by 1.7 kilometers (one mile), per year. That’s a 75% increase in speed from approximately 2.5 kilometers (1.5 miles) per year in 1973 to 4 kilometers (2.5 miles) per year in 2013.
Both Pine Island and Thwaites glaciers contribute the most to overall ice discharge—about three-fourths of the total amount documented in the study. However, scientists also documented even higher rates of increased discharge in some of the smaller glaciers. Smith and Pope Glaciers nearly tripled the amount of ice they drained into the ocean since 1973.
The research team also found that the Pine Island Glacier is accelerating along its entire drainage system—up to 230 kilometers (155 miles) inland from where it meets the ocean.
“This paper is important in showing that a glacier can actually ‘feel’ what is happening far downstream of itself,” said Thomas. “It means that if you disturb the ice sheet near the coast, the glaciers will feel the push and rapidly respond hundreds of kilometers inland.”
This finding suggests that glacier acceleration models may need to be reevaluated, Thomas added. Most current models only take into account isolated speed changes resulting from a local disturbance, rather than representing how these changes affect the glacier as a whole.

We are close to eating bait fish and jelly fish as big fish numbers plummet

by Pakalolo, Daily Kos, March  17, 2014

"When you're young, you look at the world and think what you see has been that way for a long time. When you're 5, everything feels "normal." When things change in your lifetime, you may regret what has changed, but for your children, born 30 years later into a more diminished world, what they see at 5 becomes their new "normal," and so, over time, "normal" is constantly being redefined to mean "less." And people who don't believe that the past was so different from the present might have what could be called "change blindness blindness."

Because these changes happen slowly, over a human lifetime, they never startle. They just tiptoe silently along, helping us all adjust to a smaller, shrunken world."
Daniel Pauly
They came, they fished, then snap! They posed. Right in front of their Big Catch — and thereby hangs a tale.

For generations, tour boats have been collecting fishing enthusiasts in Key West, Fla.: taking them for a day of deep sea casting; providing them rods, bait, companionship; and then, when the day ends, there's a little wharf-side ceremony. Everyone is invited to take his biggest fish and hook it onto the "Hanging Board"; a judge compares catches, chooses a champion, and then the family that caught the biggest fish poses for a photograph. The one up above comes from 1958. Notice that the fish on the far left is bigger than the guy who, I assume, caught it; and their little girl is smaller than most of the "biggies" on the board. Those aren't little people. Those are big fish.
Here's another one from the year before — 1957. Again, the fish loom larger than the people. Check out the guy in the back, standing on the extreme right, next to an even bigger giant.
Charter companies have been taking these photos for at least 50 years now. In some cases, they've operated from the same dock, fished in the same waters and returned to the same Hanging Board for all that time — which is why, when a grad student working on her doctoral thesis found a thick stack of these photos in Key West's Monroe County Library, she got very excited. Loren McClenachan figured she could use this parade of biggies to compare fish over time.
For example, here's a photo taken a decade after the previous shots — during the 1965-1979 period:
Courtesy of Monroe County Public Library
The fish in that one are still big, but no longer bigger than the fishermen. It's the same in this next one. Grandma and Grandpa are decidedly the biggest animals in the photo:
Courtesy of Monroe County Public Library
Let's keep going. This next photo was taken during the 1980-1985 period. It's a group shot, one of many. Everybody's displaying their biggest catches. Loren visited this wharf in 2007 and discovered, as she writes in her scientific paper, that these display boards "had not changed over time," which meant she could measure the board, and then (using the photos) measure the fish. Clearly, these fish are way smaller than the ones from the 1950s:
Courtesy of Monroe County Public Library
How much smaller? Adjusting for time of year, and after checking and measuring 1,275 different trophy fish, she found that in the 1950s, the biggest fish in the photos were typically over 6 feet — sometimes 6 feet 5 inches long. By the time we get to 2007, when Loren bought a ticket on a deep sea day cruise and snapped this picture ...
Courtesy of Loren McClenachan
... the biggest fish were averaging only a foot, or maybe a little over. That's a staggering change. The biggest fish on display in 2007 was a shark, and sharks, Loren calculated, are now half the size they used to be in the '50s. As to weight, she figured the average prizewinner dropped from nearly 43.8 pounds to a measly 5 pounds — an 88% drop. 
It's no big surprise, I suppose, that fish in the sea are getting smaller. The curious thing, though, is that people who pay 40 bucks to go fishing off Key West today have no sense of what it used to be like. Had Loren not found the fish photos, there would be no images, no comparative record of what used to be a routine catch.
In her paper, Loren says that the fishing charter tours are still very popular. The price of the tour hasn't dropped (adjusting for inflation), only the size of the fish. Looking at the photos, people now seem just as pleased to be champions as those "champs" back in the '50s, unaware that what's big now would have been thrown away then. Loren says she suspects that people just erase the past "and will continue to fish while marine ecosystems undergo extreme changes."
Goliath grouper, Epinephelus itajara, is listed as critically endangered by the IUCN (International Union for the Conservation of Nature). The largest grouper fish in the Atlantic ocean, goliaths can reach 8 feet (2.5 meters) in length, weigh 1,000 pounds and live more than 40 years. After being fished to near extinction, goliaths have been protected by a moratorium on harvest in U.S. federal and state waters since 1990 and in the U.S. Caribbean since 1993. Elsewhere in the Atlantic ocean, the species is either extinct, or critically endangered.

Over the last decade, Florida recreational and commercial fishermen have demanded a “thinning out” of the population, as fishers consider goliath groupers a major predator of spiny lobster, snapper and other grouper species, and the main reason for declines in such target species.

A study by Dr. Sarah Frias-Torres titled “Should the Critically Endangered Goliath grouper Epinephelus itajara be culled in Florida,” analyzed fisheries landing data since the 1950s, diver based surveys and published dietary studies. It concludes that :

(1) Goliath groupers eat invertebrates (worms, molluscs and crustaceans) and poisonous fish, not snappers and other groupers. Surprisingly, many of the prey consumed by goliath groupers are in turn predators of juvenile spiny lobster. Hence, goliath groupers are a fishers’ best friend, because through top-down predator control, goliaths could allow more juvenile lobsters to grow and become available to fishers.

(2) The slow recovery of the goliath grouper population in Florida is not the cause for declining lobster and snapper stocks in Florida. Instead, overfishing is the main cause.

(3) A thriving goliath grouper population could provide additional socio-economic benefits in ecotourism, and as a potential biocontrol agent for the invasive lionfish.

“Goliath groupers are a national treasure. Florida is the only place in the world where we can encounter these gentle giants, from juveniles to adults. Florida also contains 99 % of the spawning aggregation sites known worldwide. With this study in hand, we now have a strong argument to continue protection of the goliath grouper and dismiss any claims that the goliaths are destroying valuable stocks of lobster, snapper and other groupers,” said Dr. Sarah Frias-Torres, the author of this study.

Goliath groupers gather annually in spawning aggregations at offshore reefs and wreck sites throughout the Caribbean and parts of Florida. During filming for Americas Underwater Treasures, a two-hour PBS special documenting all the U.S. National Marine Sanctuaries as part of the Ocean Adventures series, Jean-Michel, Fabien and Celine Cousteau witness a congregation of these enormous fish. Dive under the waves with them in this short film and discover the goliath grouper.

Overfishing Facts

Since 1950, one in four of the world’s fisheries has collapsed due to overfishing.

77% of the world's marine fish stocks are fully exploited, over-exploited, depleted or slowly recovering.

The cod fishery off Newfoundland, Canada collapsed in 1992, leading to the loss of some 40,000 jobs in the industry. Twenty years later, the fishery has yet to recover.

Scientists estimate that 90% of the world’s large fish have been removed from our oceans, including many tuna, sharks, halibut, grouper, and other top level predators which help maintain an ecological balance.

Of the 3.5 million fishing vessels worldwide, only 1.7% are classified as large-scale, industrial vessels, yet these vessels take almost 60% of the global fish catch.

Tuna purse seine vessels using Fish Aggregating Devices entangle and kill a million sharks a year in the Indian Ocean alone.

Every year, the world's fishing fleet receives roughly $30 billion in government subsidies. Most of the subsidies are given to the large-scale, industrial sector of the fishing industry.

Industrial fishing fleets kill and discard about 27 million tons of fish on average each year. That means that one-quarter of the annual marine fish catch is thrown overboard dead. For every kilo of shrimp landed, over 10 kilos of tropical marine life is caught and dies.

Bottom trawling, a fishing method which involves dragging giant nets and chains across the seafloor, damages fragile corals and sponges which provide habitat for fish and creates scars on the ocean bottom which can even be visible from space.

Globally more than US$20 billion is lost to pirate fishing each year, much of which involves European or Asian vessels. The United Nations estimates that Somalia loses US $300 million a year to the pirates; Guinea loses US $100 million.

The Patagonian toothfish (often sold as Chilean sea bass) fisheries around Crozet, Prince Edward and Marion Islands were fished to commercial extinction in just two years.

Commercial fishing boats also kill tens of thousands of albatrosses and hundreds of thousands of other seabirds, mostly by longline fishing.  Considering that albatrosses can live 50+ years, and take over 5 years to reach breeding age, this is an unsustainable loss of a truly impressive species.

Greenpeace is working towards establishing 40% of the world's oceans as marine reserves, allowing the time and space to rebuild our oceans to healthy ecosystems.

Steve Horn: BP Lake Michigan Oil Spill: Did Tar Sands Spill into the Great Lake?

by Steve Horn, DeSmogBlog, March 28, 2014

Is it conventional crude or tar sands? That is the question. And it's one with high stakes, to boot. 

The BP Whiting refinery in Indiana spilled between 470 and 1228 gallons of oil (or is it tar sands?) into Lake Michigan on March 24, 2014, and four days later no one really knows for sure what type of crude it was. Most signs, however, point to tar sands. 

The low-hanging fruit: the refinery was recently retooled as part of its “modernization project,” which will “provide Whiting with the capability of processing up to about 85% heavy crude, versus about 20% today.”

The low-hanging fruit: the refinery was recently retooled as part of its “modernization project,” which will “provide Whiting with the capability of processing up to about 85% heavy crude, versus about 20% today.”

As Natural Resources Defense Council (NRDC) Midwest Program Director Henry Henderson explained in a 2010 article, “heavy crude [is] code for tar sands.”

Albeit, “heavy crude” is produced in places other than Alberta's tar sands, with Venezuela serving as the world's other tar sands-producing epicenter. So, in theory, if it's heavy crude that spilled into Lake Michigan, it could be from Venezuela.

But in practice, the facts on the ground tell a different story. As a January 2014 article in Bloomberg outlined, the combination of the U.S. hydraulic fracturing (“fracking”) boom and the Canadian tar sands boom has brought U.S. imports of Venezuelan oil to 28-year lows.

Which brings us to the next question: how does the Canadian “heavy crude” get to BP's Whiting refinery to begin with? Enter: Enbridge's Line 6A pipeline.

Alberta Clipper/Line 6A

Dan Goldblatt, a spokesman for the Indiana Department of Environmental Management, told DeSmogBlog he wasn't sure what type of oil was spilled into Lake Michigan from the BP Whiting refinery  — which goes back to why it's just being referred to as “oil” at this point by officials.
Goldblatt said the U.S. Environmental Protection Agency (EPA) will be looking into it as part of its investigation.

“Right now they're more focused on recovery than on what type of oil it is,” Goldblatt said. “That's a little further down the line.”

When asked about which pipeline feeds the BP Whiting refinery beast, Goldblatt told DeSmogBlog it's Enbridge's Line 6A pipeline.

Part of Enbridge's “Lakehead System,” Line 6A stretches from Superior, Wis., to Enbridge's Griffith/Hartsdale holding terminal in northwest Indiana.  

“Lakehead System serves all the major refining centers in the Great Lakes…through its connection with the affiliated Canadian pipeline,” explains Enbridge's Lakehead System website. “Total deliveries on the Lakehead System averaged 1.65 million [barrels per day] in 2009, meeting approximately…70% of the refinery capacity in the greater Chicago area.”

Enbridge's Line 67 (AKA Alberta Clipper) pipeline serves as the corridor between Alberta's tar sands and Line 6A. Alberta Clipper currently awaits a capacity expansion permit from the U.S. State Department, which it applied for in November 2012 and needs because it's a U.S.-Canada border-crossing line.

It was originally approved by President Barack Obama's State Department in August 2009.

If approved, Line 67's expansion would morph it from a 450,000 barrels per day pipeline to a 570,000 barrels per day pipeline. Its “full design capacity is 880,000 [barrels per day] of heavy crude oil,” (emphasis mine) according to the expansion application it submitted to the State Department

Hydrocarbon Technologies, which offers “market insight tools covering all segments of the global hydrocarbons market,” also points to the ties that bind Alberta's tar sands, Enbridge's Line 6A and the BP Whiting refinery.

“Once the modernisation project is complete, BP aims to increase the use of Canadian crude from oil sands via the Enbridge [Line 6A] pipeline, which runs from Alberta to Illinois,” explains Hydrocarbon Technologies.

In 2010, Line 6A spilled in a major way in Romeoville, Ill., with 6,050 barrels of oil escaping. An account in oil and gas industry trade publication PennEnergy explains the pipeline was carrying “heavy crude oil.”

“When the leak occurred, the Line 6A was transporting approximately 459,000 barrels per day of heavy crude oil,” the reporter detailed.

The “Dilbit Disaster” Connection

Line 6A is connected to the 2010 spill of over 843,000 gallons of tar sands into the Kalamazoo River, a Lake Michigan tributary. Literally.

When oil arrives at Enbridge's Griffith, Ind., terminal from Line 6A, much of it continues northeast on the connecting Line 6B pipeline.

That line was the one responsible for the “dilbit disaster,” as coined by InsideClimate News, because it was carrying tar sands diluted bitumen, or “dilbit.” More than three years after that spill, clean up efforts are still ongoing.

“Tar Sands Name Game”

After the 2010 Kalamazoo River, the same debate over what type oil had spilled ensued. Chicago-based investigative journalist Kari Lydersen coined it the “tar sands name game.”

“[L]inguistic gymnastics around the definition of tar sands have a long history,” she wrote. “Industry officials have sought to avoid the increasingly negative connotations of tar sands extraction, which has a devastating effect on boreal forests and produces huge carbon emissions.”

And of course, it's called “heavy crude” for a reason: it's heavy. That means it can and will sink in freshwater sources like Lake Michigan or the Kalamazoo River. It did just that in Kalamazoo, making it exceedingly difficult to clean up.

With a drinking water source for seven million people at stake, this “tar sands name game” is one with high stakes indeed.
