Peter Wadhams: Arctic sea ice gone in 3 years

Arctic sea ice will vanish within three years, says expert

Dr Richard Dixon: 'Sea ice loss is one reason we re getting colder summers'

ARCTIC sea ice has melted to a record low, confirming experts’ fears about the “devastating” impact of climate change on the planet.
Figures published yesterday from the National Snow and Ice Data Centre (NSIDC), in the United States, reveal that sea ice in the Arctic has dropped to its lowest level since satellite recording started 30 years ago.
It is the sixth year in a row that a new record low has been recorded, following consecutively worsening melts first identified in 2007.
There is now 40% less sea ice in the polar region than the average levels recorded between 1979 and 2000.
With melting season still not over, concerns are growing that in a few years there will be no summer sea ice at all – spelling disaster for wildlife such as polar bears, which rely on ice to hunt.
Environmentalists, who have long warned that this year would bring a record low, renewed demands for politicians and businesses to do more to cut carbon emissions. Peter Wadhams, professor of ocean physics at Cambridge University, who was branded “alarmist” after he first detected “substantial thinning” of sea ice in 1990, said: “The entire ice cover is now on the point of collapse.
“The extra open water already created by the retreating ice allows bigger waves to be generated by storms, which are sweeping away the surviving ice. It is truly the case that it will be all gone by 2015. The consequences are enormous and represent a huge boost to global warming.”
He said that while reducing carbon emissions was the only solution, geo-engineering techniques – including one proposed by a Scottish professor – should be “urgently” explored.
The proposal by Professor Stephen Salter at Edinburgh University, which was revealed earlier this year, involves building towers that would spray sea water into the sky to help create white clouds.
The theory is that whiter clouds will help reflect the sun’s rays back into space to help keep the Earth cooler.
Dr Richard Dixon, director of WWF Scotland, said Scotland must also do more to achieve its new carbon emission targets, the first of which were recently missed.
He said: “This is not unexpected but it is extremely bad news. These satellite images show what we are doing to the planet and while climate change has gone off the political agenda recently, things have got worse and governments and big business must do more to fix that.”
He added that while many other countries are experiencing temperatures rising as a result of global warming, Scotland was getting colder.
“Polar ice shapes the weather systems in Scotland and the 
north-west of Europe, and sea ice loss is one reason why we’re getting colder summers and have had very cold winters in the last few years.”
NSIDC stated: “Arctic sea ice fell to 1.58 million square miles on 26 August, 2012. This was 27,000 square miles below the 
18 September, 2007, extent of 
1.61 million square miles.
“The six lowest ice extents in the satellite record have 
occurred in the last six years.”

Ice cover on N Polar view will be irreversibly gone soon unless value of money and how it is used is linked to the urgency of situation at hand of keeping Earth alive in real time and with accurate and suddenly applied updates as needed as the situation changes. Earth, her people are not even paying attention nor is there peace throughout the Earth as the oil keeps getting drilled even as CH4, the main component of Natural Gas is about to spontaniously release in large degree due to heat up of Arctic. game on to keep Earth below 2C -people treated it like a joke. Earth is now set in traces to go well above that and likely not stop till life is gone.

And our " leaders" are spineless .. Not willing to deal with it. God help us if Romney is elected.. He treats it like a bad joke and has called it " fiction"! What ignorance

Can't disagree.
