"greenland's ice cap, which covers more than 80 percent of the island, is melting faster than expected because of global warming, a danish researcher said on monday.

the 1.8-million-square-kilometre (695,000-square-mile) ice cap, which accounts for 10 percent of the planet's fresh water, is losing about 257 cubic kilometres (62 cubic miles) of ice per year.

in 2080, it is expected to lose 465 cubic kilometres (111 cubic miles) per year, according to new estimates presented by a danish-us team of scientists at the international research center in fairbanks, alaska.

"the ice cap's melting season beat a new record in 2007, corresponding to a loss of 50 percent of the ice's total surface. and this record will not be the last one," he warned.

"the ice melt at the end of the 2070s will rise to 66 percent, or about 1.204 million square kilometres," said mernild, adding that the melting process was "occurring at faster rate than previously predicted."

the research team's calculations, based on climate models and the un climate panel's predicted scenarios, showed that "the average air temperature (in greenland) will rise by some 2.7 degrees by the end of the century," he said.

"climate sceptics such as nigel lawson who argue that global warming has stopped have their "heads in the sand", according to the uk's met office.

a recent dip in global temperatures is down to natural changes in weather systems, a new analysis shows, and does not alter the long-term warming trend.

the office says average temperatures have continued their rising trend over the last decade, and that humans are to blame.

in a statement published on its website, it says: "anyone who thinks global warming has stopped has their head in the sand.

"the evidence is clear, the long-term trend in global temperatures is rising, and humans are largely responsible for this rise. global warming does not mean that each year will be warmer than the last."

"...vicky pope of the met office said the new research was in response to high-profile claims made by lawson the former chancellor, and others that the recent cooling showed that fears of climate change are overblown, and that temperatures are unlikely to rise as high as predicted.

she said: "i think it has confused people. we got a lot of emails asking whether global warming had stopped and it prompted us to look at the data again and try and understand the situation better.""

"...despite the recent cooling, average temperatures are still rising at 0.09c per decade, the office says - down from the record 0.33c per decade measured during the 1990s."

"scientists from florida state university and the university of wisconsin report in the journal nature the most powerful tropical storms are becoming more intense. they analyzed 15 years of satellite and other data from nearly 200 tropical storms.

three years ago, another study found a near doubling of the number of the strongest hurricanes."

"...the underlying causes of the phenomenon are open to debate. however, the data strongly suggests wind speeds will increase in the strongest tropical storms for the next several years."

"the earth will warm about 2.4° c (4.3° f) above pre-industrial levels even under extremely conservative greenhouse-gas emission scenarios and under the assumption that efforts to clean up particulate pollution continue to be successful, according to a new analysis by a pair of researchers at scripps institution of oceanography at uc san diego.

that amount of warming falls within what the world's leading climate change authority recently set as the threshold range of temperature increase that would lead to widespread loss of biodiversity, deglaciation and other adverse consequences in nature. the researchers, writing in the online edition of the proceedings of the national academy of sciences, argue that coping with these circumstances will require "transformational research for guiding the path of future energy consumption."

this paper demonstrates the major challenges society will have to face in dealing with a problem that now seems unavoidable," said the paper's lead author, scripps atmospheric and climate sciences professor v. ramanathan."

"global warming could rapidly accelerate as millions of tons of methane escape from beneath the arctic seabed, scientists warned today.

huge deposits of the greenhouse gas - 20 times more potent than carbon dioxide - are rising to the surface as the arctic region heats up, according to preliminary findings.

researchers found massive stores of sub-sea methane in several areas across thousands of square miles of the siberian continental shelf and observed the gas bubbling up from the sea floor through 'chimneys', according to newspaper reports."

"...the researchers believe escaping sub-sea methane is connected to rises in temperatures in the arctic region."

"...'the growing evidence for release of methane in this inaccessible region may suggest that the permafrost lid is starting to get perforated and thus leak methane... the permafrost now has small holes.

'we have found elevated levels of methane above the water surface and even more in the water just below. it is obvious that the source is the seabed.'

the average temperature of the region has risen by 4c over recent decades,leading to a major decline in the area of the arctic ocean covered by summer sea ice."

part 1: temperature trends

1. the past decade
proponents of the anthropogenic global warming (agw) doctrine, such as the un’s intergovernmental panel on climate change (ipcc), argue that emissions of co2 from the burning of fossil fuels are the main cause of the ‘unprecedented’ increase in worldwide surface temperatures since the late 1970s. other scientists dispute the claim that recent warming has been in any way unusual. they argue that the earth has been warming for most the past 400 years, since the depth of the little ice age, and that climate continues to be governed mainly by natural solar, oceanic and tectonic factors and related changes in cloudiness.

global temperatures peaked in 1998, the year of a very strong el niño, which was neither caused by global warming nor predicted by climate models. since then, co2 levels have risen sharply (by over 4%), yet global temperatures have remained essentially flat. since late 2001 all the four major official sources of global temperature data show a slight cooling trend (fig. 1.1).

is oxygen depletion more worrying than global warming?

until recently, i had been under the impression that oxygen levels in the atmosphere are quite stable around 21 per cent, and have been so for a long time. however in a recent discussion about burning coal as fuel, i came across some interesting information that disproves the concept of a stable oxygen level.

historical trends, as explained in atmospheric oxygen, giant paleozoic insects and the evolution of aerial locomotor performance, r. dudley, jexb, and dudley show a high of about 35% just before the beginning of the permian, with a rapid decline to a low of about 13-14% near the beginning of the triassic, then a small spike at about 17% in mid triassic, another drop to about 14-15% early in the jurassic, a sudden climb to about 21% by mid-jurassic, then a gentle climb to about 26% early in the tertiary, and a rather constant, steady decline to the present "20.9%."

but even now, we are not necessarily assured of a more-than-20-per cent oxygen level in the air.

"global warming calculations have been too optimistic, and the sea level round the globe is likely to rise a full metre this century, two senior german scientists warned wednesday. hans joachim schellnhuber, who heads the potsdam institute for research on global warming effects and jochem marotzke, a leading meteorologist, said un-backed data on climate change, predicting a rise of 18 to 59 centimetres, was out of date.

“we now have to expect that the sea level will rise by a metre this century,” - said schellnhuber in berlin.""

"...schnellnhuber, who is official adviser to german chancellor angela merkel on climate-change issues, said the new findings employed data unavailable to the intergovernmental panel on climate change (ipcc) for its most recent global warming report.

the two experts said the ipcc report had been based on data up to 2005 only, but since then ice loss in the arctic had doubled or tripled.

schnellhuber charged that 20 percent of the loss of the ice sheet on greenland could be directly linked to the added carbon dioxide emissions from new chinese coal-fired power stations."
