A few days ago, Climate Progress brought you “Breaking News: The Great Ice Age of 2008 is finally over — next stop Venus!” That scientific finding was based on the NASA (and Hadley Center) temperature data through the end of March. Now NOAA’s National Climatic Data Center (NCDC) weighs in with its data (here), reaffirming the end of the Great Ice Age of 2008:
Based on preliminary data, the globally averaged combined land and sea surface temperature was the second warmest on record for March and the January-March year-to-date period ranked eleventh warmest.
March 2008 missed the record for the warmest March (2002) by a whopping 0.07°F. March 2008 was the warmest March over land in the record, beating the previous record by nearly 0.3°F. And it was the warmest March over land and sea in the northern hemisphere on record by 0.2°F .
Once again, the geographical distribution of the warming continues to be really, really bad news for those worried about …
… the land of the
permafrost permamelt, where it is running upwards of 4°-9°F warmer than normal. This is worrisome because:
- Siberia contains probably the world’s largest amount of carbon locked away in the permafrost.
- The permafrost is increasingly not so perma.
- Much of that carbon would be released as methane, which is 23 times more potent a greenhouse gas than carbon dioxide.
I’m (still) working on a two-part permamelt update for Climate Progress. Definitely not for the squeamish.
In any case, I know how much stock the deniers put in one month’s worth of data, so I will try to keep them — and you — up to speed on our (climate) progress toward record warming.
