Researchers have just updated one of the most prominent global temperature records to include information collected in the Arctic—and the new data reveals that 2010 was indeed the warmest year we've got on the books.
Researchers have updated HadCRUT - one of the main global temperate records, which dates back to 1850. One of the main changes is the inclusion of more data from the Arctic region, which has experienced one of the greatest levels of warming.The updated research has been published in the Journal of Geophysical Research.
The amendments do not change the long-term trend, but the data now lists 2010, rather than 1998, as the warmest year on record.
Previously, 2010 was held to be tied for the hottest year on record with 1998, an El Nino year that was so hot that it gave rise to the idiotic global cooling meme you still hear climate deniers push once in a while (since no single year reached the sky-high temps of 1998 in the 00s, they'd argue that the world was instead cooling, despite the fact that the general trend was clearly towards warmer and warmer temps in every available data set).
That argument was ridiculous then, and it's even more ridiculous now—the new data shows that the hottest year is clearly 2010, followed by 2005, then 1998.
This data is more in line with that of the U.S. agencies (NASA and NOAA) and confirms many of scientists' worsening fears about the advance of global warming.
