Confirming measurements announced last week by the European Climate Change Service, NASA today announced that February 2017 was the second-warmest February on record, just 0.20 degrees Celsius cooler than last year’s record reading. The analysis by scientists at NASA’s Goddard Institute for Space Studies showed that the month was 1.1 degrees Celsius warmer than the 1951-1980 mean.
The monthly analysis by the GISS team is assembled from publicly available data acquired by about 6,300 meteorological stations around the world, ship- and buoy-based instruments measuring sea surface temperature, and Antarctic research stations.
The analysis shows that North America and Siberia, along with the Arctic, were the hot spots in February, with most of Europe also warmer than average. Cool areas included parts of the Pacific Northwest and the Middle East.
The pattern was reflected by the string of daily and monthly high temperature records set in the eastern U.S. The Arctic has also been record warm all winter, with sea ice in the region hovering near record low extent for several months in a row.
The persistent warmth comes despite the end of a warm El Niño Pacific Ocean phase, when a switch to La Niña — the cool part of the ENSO cycle — often brings a global cool down. Australian climate scientists this week said that yet another El Niño could be brewing in the Pacific for next year.
According to the Australian Bureau of Meteorology, there’s a 50 percent chance the El Niño threshold could be reached by July, as projections show steady warming of the central tropical Pacific Ocean over the next six months. So far, however, wind and cloud patterns have not shown any big shift away from neutral conditions. The researchers said it’s difficult to make an accurate forecast during the transition season.
SUMMIT COUNTY — Despite a bitter cold snap across large parts of central and eastern Europe, global temperatures in February were still .67 degrees above the long-term average for the month, based on records going back 133 years.
It was the coolest February since 2008, but the 324th month in a row with above average temperatures, according the National Climatic Data Center’s monthly report. The last month with below average temperatures was February 1985.
Warmer-than-average temperatures were reported across most of Canada and Alaska, the eastern United States and north-central Russia, and southern Greenland. Cooler-than-average readings prevailed in northeastern Africa, most of Europe and central Asia and most of Australia. Continue reading “Climate: Global temps above average in February”→
April 2010 the warmest ever, despite low solar activity
By Bob Berwyn
SUMMIT COUNTY — Global warming skeptics who rely on sunspot theories to explain warming atmospheric and ocean temperatures may have to go back to the drawing board. The latest figures from NASA show that April 2010 was the hottest on record, at .50 degrees above the long-term average, according to www.climateprogress.org.
Probably operating under the theory that the best defense is a good offense, global warming deniers have recently been trying to spread the message that the Earth has actually been cooling in the past few years, but there is no evidence to that effect, just a targeted effort to spin the media and distort the truth.
