Record heat ties 2005 -- the previous hottest year on record

According to climatologists at the National Aeronautics and Space Administration's (NASA) Goddard Institute for Space Studies (GISS) in New York, 2010 was a very hot year.  While anyone who witnessed the Vikings Metrodome collapse [video] might not have seen this coming, NASA says that data from 1,000 climate stations shows 2010, as a whole, to be statistically tied for being the hottest year in recorded history [press release].

The man leading the report was infamous climatologist James Hansen, well-known as being Al Gore's climate advisor; for his claims that oil companies were committing "crimes against humanity" by doing business; and for receiving a $250,000 grant from a nonprofit run by the wife of Democratic Senator John Kerry. 

Hansen states in the report, "If the warming trend continues, as is expected, if greenhouse gases continue to increase, the 2010 record will not stand for long."

Much uncertainty remains, however.  NASA's data comes from 1000 meteorological stations around the world, satellite observations of sea surface temperature, and Antarctic research station measurements.  But NASA must choose how to process that data when measurements conflict.  In the past, ground based stations have reportedly shown anomalous heating in select regions (such as Russia), but NASA chose to throw out or reduce the statistical significance of satellite measurements, which showed far cooler temperatures.

It is unknown if there are similar discrepancies in this year's temperatures, but one would hope that the data is carefully scrutinized by independent interests given Dr. Hansen's vested financial interest in showing the Earth is warming and mankind is causing it.

If the NASA data holds up, the average surface temperature in 2010 was 1.34 degrees Fahrenheit warmer than the average temperature from 1951 to 1980.  Since the 1970s, NASA says statistics show the Earth to be warming 0.36 degrees Fahrenheit a decade.

2010 was within 0.018 degrees Fahrenheit of 2005, the previous record holder, earning it a tie.  In a tie for third place are 1998, 2002, 2003, 2006, 2007 and 2009.  NASA says its analysis closely matches separate analysis from the Met Office Hadley Centre in the United Kingdom and the National Oceanic and Atmospheric Administration's National Climatic Data Center.

Dr. Hansen reports that the record warmth was especially exceptional given that 2010 was the start of a strong La Niña pattern, which brings cool sea surface temperatures to the eastern tropical Pacific Ocean and should have offered a cooler global temperature.  He states, "Global temperature is rising as fast in the past decade as in the prior two decades, despite year-to-year fluctuations associated with the El Niño-La Niña cycle of tropical ocean temperature."

While this data might worry some, it could actually be happy news for mankind.  The slow, gradual warming shown in the report would likely over time open new shipping routes and improve agricultural viability in many regions.  While some areas might be gradually rendered uninhabitable (e.g. small low-lying islands), humans would naturally migrate to new homes, and the climate change would likely make some previously minimally habitable regions more hospitable.

Loss of species from climate change has certainly been suggested as a possible concern as well, but biodiversity in the Earth's warming periods has increased, not decreased historically.  Current temperatures are still far below these epochs of lush biodiversity that lie in the Earth's distant past.  The destruction of the rainforest and pollution of the sea have been put on the back burner during the climate debate, but represent far more serious immediate threats to our planet's biodiversity.

Other pressing questions include how fast warming will proceed and what other factors may be at play, besides greenhouse gases.  A recent study suggests that atmospheric dust levels may have significantly different effects on global temperature than previously thought.  Historical levels of atmospheric dust are poorly understood.  Further, it is unknown how much the Earth will dampen temperature increases.  Past history suggests that the Earth's biosphere resists the kind of run-away warming some experts' models have predicted, at least to a point.

Despite these distinctions, the NASA report is certainly intriguing and will likely be keenly observed and analyzed by those in the fields of agriculture and urban planning.

Except a warming trend would likely be exponentaial over time, so any short term "benifit" would very quickly be offset. IE: Less ice would darken the earth, and as we all learned in basic chemistry: White reflects, black absorbs.


So I suppose 100 years ago we were at the optimal temperature, and now we're slipping exponentially upward. And if we had cooled slightly instead of warming 100 years ago, there would be more ice reflecting more sun and we would be instead slipping downward toward an ice-covered earth? Give me a break.

I also find it hilarious that the author points out the "financial interests" in "proving" GW, but fails to cite any such interest, or point out those same interests for those hoping to prove the exact opposite.


So you say he didn't cite such interests. Let me help:

Obviously you'll find interests for both sides, I'll give you credit for that. But to suggest nobody is profitting from the AGW movement is incredibly naive, IMO.
