Re: Record breaking heat and its climate connection
- The IPCC states that the frequency and duration of heat waves worldwide have increased since 1950.
- Over the past 30 years, the geographic area experiencing extreme summer heat has increased by more than ten-fold.
- Climate change made Russia’s 2010 heat wave five times more likely to occur.
- Record breaking high temperatures have outnumbered lows in the US by two to one. (National Climate Assessment, Ch. 2, figure 2.7, shown below)
