As I just wrote the other day, NOAA found that 2010 was tied for the hottest year on record. NASA’s 2010 data now confirm this.
Global surface temperatures in 2010 tied 2005 as the warmest on record, according to an analysis released Wednesday by researchers at NASA’s Goddard Institute for Space Studies (GISS) in New York.
The two years differed by less than 0.018 degrees Fahrenheit. The difference is smaller than the uncertainty in comparing the temperatures of recent years, putting them into a statistical tie. In the new analysis, the next warmest years are 1998, 2002, 2003, 2006, 2007 and 2009, which are statistically tied for third warmest year. The GISS records begin in 1880.
The analysis found 2010 approximately 1.34°F warmer than the average global surface temperature from 1951 to 1980. To measure climate change, scientists look at long-term trends. The temperature trend, including data from 2010, shows the climate has warmed by approximately 0.36°F per decade since the late 1970s.
“If the warming trend continues, as is expected, if greenhouse gases continue to increase, the 2010 record will not stand for long,” said James Hansen, the director of GISS….
The record temperature in 2010 is particularly noteworthy, because the last half of the year was marked by a transition to strong La Niña conditions, which bring cool sea surface temperatures to the eastern tropical Pacific Ocean.
“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,” Hansen and colleagues reported in the Dec. 14, 2010, issue of Reviews of Geophysics.
Sounds nice, eh?
And no way to stop it… unless we switch to a clean energy economy and stop burning so much fossil fuel….
Dr Joe Romm of Climate Progress also notes: “These records are also especially impressive because we’ve been in ‘the deepest solar minimum in nearly a century.'”
Regarding its findings, the NOAA noted the following this week:
According to NOAA scientists, 2010 tied with 2005 as the warmest year of the global surface temperature record, beginning in 1880. This was the 34th consecutive year with global temperatures above the 20th century average….
According to the Global Historical Climatology Network, 2010 was the wettest year on record, in terms of global average precipitation….
“The year 2010 now has the most national extreme heat records for a single year–nineteen,” Jeff Masters noted in November. “These nations comprise 20% of the total land area of Earth. This is the largest area of Earth’s surface to experience all-time record high temperatures in any single year in the historical record.”
The 12 hottest years on record have occurred since 1997.
