1998 remains hottest year in recorded history. 2010 falters at the finishing line



According to UAH (satellite) data, 1998 (+0.424 deg. C) barely edged out 2010 (+0.411 deg. C), which suggests a whisker of a win for 1998. The margin 0.01 is not statistically significant but what is significant is that for the last 12 years, there is no evidence of accelerating global warming trend. There is of course an underlying warming trend since 1979, but it is not linear, and basically flatlined over the last 12 years. 





If 2010 is one of the warmest in recorded, then 2011 is likely to be one of the coldest as evident from Dr Roy Spencer's comments:
 

 “The following plot shows global average sea surface temperatures from the AMSR-E instrument over the lifetime of the Aqua satellite, through Dec 31, 2010. The SSTs at the end of December suggest that the tropospheric temperatures in the previous graph still have a ways to fall in the coming months to catch up to the ocean, which should now be approaching its coolest point if it follows the course of previous La Nina’s”
