Human-caused global warming easily overwhelms much-hyped “cold snap”
Yes, the mid-Atlantic region appears headed toward an epic snow storm as “amazing moisture feeds into what is already a gigantic system,” according to the Capital Weather Gang.
But while the anti-science crowd will no doubt tout that as evidence we aren’t warming — just as they did with the “cold snap” in early January — in fact, climate science predicts we will see more extreme precipitation events year-round as warming puts more moisture into the atmosphere [see Was the "Blizzard of 2009"³ a "global warming type" of record snowfall "” or an opportunity for the media to blow the extreme weather story (again)?].
Indeed, the January “cold snap” not only didn’t prove the case for (nonexistent) global cooling — it turns out that January was uber-hot around the globe! As leading anti-science guy Roy Spencer posted Thursday (including the figure above):
The global-average lower tropospheric temperature anomaly soared to +0.72 deg. C in January, 2010. This is the warmest January in the 32-year satellite-based data record….
Note the global-average warmth is approaching the warmth reached during the 1997-98 El Nino, which peaked in February of 1998.
Of course, right now we’re only in a moderate El Nino. In 97-98, we had a monster El Nino. And Spencer doesn’t mention that this record is especially impressive because we’re at “the deepest solar minimum in nearly a century.”
The point is, notwithstanding the all-too-effective disinformation campaign of the anti-science crowd, it’s getting hotter “” thanks primarily to human emissions.
The satellite record itself clearly shows the long-term warming trend, especially when you remove the stratospheric cooling influences.
You can plot the UAH temperature data yourself:
I’ll blow up relevant part:
Even the supposed record “cold snap” in early January was so localized that the Earth as a whole was relatively quite hot that first week.
While the El Ni±o has started to weaken, it is still “expected to continue at least into the Northern Hemisphere spring 2010,” according to NOAA. Barring a major volcano, 2010 remains likely to be the hottest year on record.
