Roy Spencer says:
a few answers:
Ice near the poles wont melt if most of the global atmosphere at lower latitudes does not warm. Atmospheric feedbacks kick in faster than ice-albedo feedbacks. And, has been mentioned, the satellite data are not as good at the high latitudes, anyway.
If I give more of the technical details to support my conclusions, people complain they dont understand. If I dont include the details to keep it simple, they complain that Im not justifying my claims. Look, my articles are not peer-reviewed science, people. Im just keeping people abreast of progress in research they are paying me to do. :)
The global cloud cover data are not good enough to do long-term trends with. Until the Terra MODIS data started in 2000, we could not be confident of any long-term cloud changes people think they see in the satellite data. Only a 2% change is needed to cause global warming or cooling. Long-term cloud changes on a regional basis can fool you because an increase in cloudiness in one region is usually compensated for by a decrease in an adjacent region.
Yes, its only 7 years of data. But the fact that none of the climate models show the negative feedbacks the satellites show when those are computed the same way on the same time scale from climate model output strongly suggests something might be wrong with those models feedbacks .
does this all sound like the science is settled?
