Recently, work has shown that if you analyse long-term global temperature rise for windy days and calm days separately, there is no difference.

He said recent reports by the Intergovernmental Panel on Climate Change (IPCC), which has estimated the possible global temperature rise by 2100 as 5.8 degrees C, had confirmed a "spectacular" retreat and collapse of ice shelves on the Antarctic peninsula.
But it's not happening anything like fast enough to meet goals outlined by the Intergovernmental Panel on Climate Change (IPCC), which talks of emissions peaking by 2020, preferably by 2015, if the target of limiting the global temperature rise to 2C from pre-industrial levels is to be met.
This succinctly expresses my understanding of the situation: that human (anthropogenic) emissions of CO2 are causing the global temperature to rise, and the consequences of this are likely to be catastrophic.
Global warming alarmists claim temperature rise during the past century was unprecedented, with temperatures rising especially rapidly during the latter half of the 20th century.
Many legal policy experts, including the Washington Legal Foundation, have long insisted that the debate over the effects of carbon emissions on the rise in global temperature is strictly a political question that should not be decided in the courts.
As it currently stands, the UN Framework Convention on Climate Change has set a target of limiting the rise in global mean temperature to 2C (3.6F) above pre-industrial levels.
His book addresses the argument in cost-benefit terms, and concludes that spending 1-2% of global output to avoid a significant temperature rise is a bargain worth taking a similar conclusion to that in his original 2006 study.
However the paper concluded that, "in the absence of volcanic eruptions, global temperature is predicted to continue to rise, with each year from 2013 onwards having a 50 % chance of exceeding the current observed record".
Writing in the Journal Nature in April, researchers said pledges made at December's UN summit in Copenhagen are unlikely to keep the rise in the global mean temperature to 2C (3.6F) above pre-industrial levels.
IPCC's worst-case scenario, which is about a 7 degree Fahrenheit rise in temperature, shows a global sea level gain of 10 to 23 inches.
This ocean acidification theory is very convenient for global warming alarmists because it allows them to claim a major global warming-related crisis even when global temperatures fail to rapidly rise or rise in a manner that does not produce temperature-related crises.

If global temperature rises by about 1 degree Fahrenheit in the next century, scientists estimate the sea level will rise seven to 15 inches.
