If there’s one thing climate alarmists have become quite good at, it’s retrofitting both their computer models and the climate phenomena those models predict whenever they fail to do so correctly. And whether projecting increases in temperature, sea levels or atmospheric carbon dioxide – that means often.  But some of the most brazen intellectual corruption warmists have committed under fire concerns the sometimes polar opposite trends of Arctic and Antarctic sea ice. Back in 2005, NASA attempted to excuse the failure of their climate models to predict continued southern ice expansion as an omission of the “snow-to-ice conversion” process in...

1st paragraph (with link to abstract): "Our recent paper “Climate response to regional radiative forcing during the twentieth century”, has generated some interesting discussion (some of it very 'interesting' indeed). So this post is an attempt to give a better context to the methods and implications of the study." Yet more aerosols: Comment on Shindell and Faluvegi Most intriguing paragraph: "In the absence of increasing greenhouse gases, our large historical emissions of sulfate precursors would have led to substantial cooling from sulfate, and the subsequent reduction in emissions would have brought temperatures back towards their previous level. So reduced sulfate...

Scientists at Harvard University have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming. The finding, published in Geophysical Research Letters, provides more evidence of the intertwining of severe weather and global warming by demonstrating a mechanism by which storms could drive climate change. Many scientists now believe that global warming, in turn, is likely to increase the severity of tropical cyclones. "Since water vapor is an important greenhouse gas, an increase of water vapor in the stratosphere would warm the Earth's surface," says David M. Romps, a research associate in Harvard's Department of...
