Satellite measured temperature anomaly data for the lower troposphere was just released from Remote Sensing Systems.
Too no real surprise, October 2011 trended cooler overall across most of the planet, however, despite the drop off, the global temperature anomaly was still a shade above normal, coming in at +0.089 C.
Overall, October 2011 will go down as the 15th coolest October in the RSS satellite measured record, which began back in 1979.
The RSS anomaly map from Remote Sensing Systems indicates that much of northeast Canada, Europe and central Asia was warmer than normal for October. However, it is clear that widespread cooling over the large Pacific and southern Atlantic were responsible for the overall cooling trend globally.
The RSS image below shows the latest decadal temperature trend for the lower troposphere globally. It is still upward at +0.141 C per decade.
By the way, October 2011 ended up slightly cooler than normal for the continental U.S. with an anomaly reading of -0.078 C.
MSU/AMSU data are produced by Remote Sensing Systems and sponsored by the NOAA Climate and Global Change Program. Data are available at www.remss.com.
Sea ice extent and volume continues to run well below normal.
The first three-quarters of this year the warmest such period on record globally going back to 1880.
At the current pace, this year will easily end up as the warmest year on record globally.
The risk of flooding similar to Hurricane Sandy in the New York City area is likely to be significantly higher by the end of the century.
Human-caused climate change has nearly doubled the amount of area burned by western U.S. forest fires over the past 30 years.
