"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."

Newly released data from the UK Met Office shows that during the first half of 2008 the global temperatures was more than 0.1 Celcius cooler than any other year after 2000. The reason for this is La Nina, an ocean-atmosphere phenomenon that has a cooling effect on the earth.

But this doesn’t mean the deniers are correct about anything else. Scientists still expects that 2008 will be the 10th warmest year since 1850. And the UK Met Office says that the global temperatures will continue to rise again when La Nina eases away.

“The big thing that’s been happening this year is La Nina, which has lowered global temperatures somewhat,” said John Kennedy, climate monitoring and research scientist at the Met Office’s Hadley Centre.

“La Nina has faded in the last couple of months and now we have neutral conditions in the Pacific,” he told BBC News.

Dr Kennedy also said that “2008 will still be significantly above the long-term average,” and that “there’s been a strong upward trend in the last few decades, and that’s the thing to focus on.”

Even during the temporarily cooling effect from La Nina we see evidence that the rapid man-made warming continues. Images from National Aeronautics and Space Administration satellites show continued breakup of 2 of Greenland’s largest glaciers. According to Canadian authorities the Northwest Passage is navigable. Recently scientists warned that the Arctic could become ice-free during the summers as early as 2013. And just yesterday a huge chunk of ice shelf nearly the size of Manhattan broke away in Canada’s northern Arctic.

The storms over the Alaska’s Beaufort Sea last week brought with them not just bad weather but also streams of hot air into the Arctic. Satellite images that were taken shortly after could show that the ice caps had started to “disintegrate dramatically.” And because of that the scientists believes that the melting could exceed last year’s record loss of ice.

‘It is a neck-and-neck race between 2007 and this year over the issue of ice loss,’ said Mark Serreze, of the US National Snow and Ice Data Centre in Boulder, Colorado. ‘We thought Arctic ice cover might recover after last year’s unprecedented melting – and indeed the picture didn’t look too bad last month. Cover was significantly below normal, but at least it was up on last year.

‘But the Beaufort Sea storms triggered steep ice losses and it now looks as if it will be a very close call indeed whether 2007 or 2008 is the worst year on record for ice cover over the Arctic. We will only find out when the cover reaches its minimum in mid-September.’

These huge losses of Arctic sea ice will result in “major meteorological, environmental and ecological” consequences, such as: More and heavier storms being swept into Britain, polar bears and seals losing their habitats, rising sea levels and a further increased in global temperatures.
