Climate institutions and scientists are warning that 2010 might end up as one of the hottest years ever recorded in human history. According to new data from the US National Snow and Ice Centre Data Centre (NSIDC)arctic sea ice levels is now "at its lowest physical extent ever recorded for the time of year". According to the reports this year will break the previous record low levels from 2007. The Guardian reports that:
"Satellite monitoring by the NSIDC in Boulder, Colorado, shows that the melting of sea ice has been unusually fast this year, with as much as 40,000 sq km now disappearing daily.
The melt season started almost a month later than normal at the end of March and is not expected to end until September.
Meanwhile, research from the polar science centre at the University of Washington suggests that the volume of sea ice in March 2010 was 20,300 cubic km, 38% below the 1979 level when records began."
And according to James Hansen, director of the NASA Goddard Institute for Space Studies in New York and one of the world’s most prominent climate scientist, new data also shows that the global surface temperatures may also be at record levels. According to a newly released paper by Hansen and his colleagues the temperature on Earth has for the past 12 months been 0.65C warmer than previous global temperatures from 1951 to 1980. The paper also shows that the global temperature this year will break the previous record from 2005.
"It is likely that the 2010 global surface temperature … will be a record", Hansen writes.
"Global warming on decadal timescales is continuing without let-up … we conclude that there has been no reduction in the global warming trend of 0.15-0.2C/decade that began in the late 1970s."
The Guardian article has written about more findings so be sure to check that article out. Especially worth noting is the new data which shows that January to April this year has been the hottest on record so far. Climate Progress writes:
"Last month tied May 1998 as the hottest on record in the NASA dataset. More significantly, following fast on the heels of easily the hottest April — and hottest Jan-April — on record, it’s also the hottest Jan-May on record.
Also, the combined land-surface air and sea-surface water temperature anomaly for March-April-May was 0.73°C above the 1951-1980 mean, blowing out the old record of 0.65°C set in 2002."
And the temperature records continues! New data also shows that the temperature during January-June this year has been the hottest ever recorded by NASA.
"It’s all the more powerful evidence of human-caused warming “because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect,” as a recent NASA paper notes."
But La Nina conditions might build up during July and August which might reduce the average heat temperature for 2010.
Meteorologist Jeff Masters also notes that new temperature records have been reached in Kuwait, Saudi Arabia, Iraq, Chad, Niger, Pakistan and Myanmar. Masters writes:
"We’ve now had eight countries in Asia and Africa, plus the Asian portion of Russia, that have beaten their all-time hottest temperature record during the past two months. This includes Asia’s hottest temperature of all-time, the astonishing 53.5°C (128.3°F) mark set on May 26 in Pakistan…. This week’s heat wave in Africa and the Middle East is partially a consequence of the fact that Earth has now seen three straight months with its warmest temperatures on record, according to NOAA’s National Climatic Data Center."
