BREAKING: IPCC AR5 report to dial back climate sensitivity | Watts Up With That? 2013

2013 2013 2013 <p>IPCC row back from predicting climate catastrophe. </p> <p>' Specifically, the draft report says that "equilibrium climate sensitivity" (ECS)—eventual warming induced by a doubling of carbon dioxide in the atmosphere, which takes hundreds of years to occur—is "extremely likely" to be above 1 degree Celsius (1.8 degrees Fahrenheit), "likely" to be above 1.5 degrees Celsius (2.4 degrees Fahrenheit) and "very likely" to be below 6 degrees Celsius (10.8 Fahrenheit). In 2007, the IPPC said it was "likely" to be above 2 degrees Celsius and "very likely" to be above 1.5 degrees, with no upper limit. Since "extremely" and "very" have specific and different statistical meanings here, comparison is difficult.<br> Still, the downward movement since 2007 is clear, especially at the bottom of the "likely" range. The most probable value (3 degrees Celsius last time) is for some reason not stated this time.<br> …<br> Most experts believe that warming of less than 2 degrees Celsius from preindustrial levels will result in no net economic and ecological damage. Therefore, the new report is effectively saying (based on the middle of the range of the IPCC's emissions scenarios) that there is a better than 50-50 chance that by 2083, the benefits of climate change will still outweigh the harm.' </p> <p>More here <a href="http://wattsupwiththat.com/2013/09/14/breaking-ipcc-ar5-report-to-dial-back-climate-sensitivity/">http://wattsupwiththat.com/2013/09/14/breaking-ipcc-ar5-report-to-dial-back-climate-sensitivity/</a></p> <br> 2013 2013 2013 <br><p>IPCC row back from predicting climate catastrophe. </p> <p>' Specifically, the draft report says that "equilibrium climate sensitivity" (ECS)—eventual warming induced by a doubling of carbon dioxide in the atmosphere, which takes hundreds of years to occur—is "extremely likely" to be above 1 degree Celsius (1.8 degrees Fahrenheit), "likely" to be above 1.5 degrees Celsius (2.4 degrees Fahrenheit) and "very likely" to be below 6 degrees Celsius (10.8 Fahrenheit).
