New Study Questions the Accuracy of Satellite Atmospheric Temperature Estimates

The recent flatness in satellite temperatures as surface temperatures continue to rise has presented a quandary for scientists.  Are both results real?  Is there some reason they diverge?  Is one measurement more accurate than the other?  This is one of the areas of very active research.

A contribution to this question appeared last week by researcher Fuzhong Weng and his colleagues.  The paper, published in Climate Dynamics, claimed to find the reason for much of that difference – the authors report that the satellite trends could be off (too cold) by perhaps 30%.  If true, this work would go a long way toward reconciling the differences between surface and satellite measurements.

Simply put, when you eliminate the effect of clouds, the atmosphere is warming faster than we thought and the divergence between land thermometers and satellites largely disappears.
