Draft versions seen by BBC News warn it will be hard for societies to adapt to all the likely climate impacts.

The report is set to say that a temperature rise above 1.5C from 1990 levels would put about one-third of species at risk of extinction.

More than one billion people would be at greater risk of water shortages, primarily because of the melting of mountain glaciers and ice fields which act as natural reservoirs.

The last-minute wrangling is likely to affect the degree of certainty in the final version, but not the overall direction.

The scientific work reviewed by IPCC scientists includes more than 29,000 pieces of data on observed changes in physical and biological aspects of the natural world.

Eighty-five percent of these, it believes, are consistent with a warming world.

If the last report was anything to go by then this will be all over the news tomorrow... Friday 6th April 2007 ...

and for those who wonder about the process:

Arctic Sea Ice Narrowly Missed Record Low In Winter 2007

The maximum extent of Arctic sea ice in winter 2007 was the second lowest on satellite record, narrowly missing the 2006 record, according to a team of University of Colorado at Boulder researchers.

"This year's wintertime low extent is another milestone in a strong downward trend,"

NASA Finds Arctic Replenished Very Little Thick Sea Ice In 2005

A new NASA study has found that in 2005 the Arctic replaced very little of the thick sea ice it normally loses and replenishes each year. Replenishment of this thick, perennial sea ice each year is essential to the maintenance and stability of the Arctic summer ice cover.

A new NASA study has found that in 2005 the Arctic replaced very little of the thick sea ice it normally loses and replenishes each year. Replenishment of this thick, perennial sea ice each year is essential to the maintenance and stability of the Arctic summer ice cover.

Kwok found that after the 2005 summer melt, only about four percent of the nearly 2.5 million square kilometers (965,000 square miles) of thin, seasonal ice that formed the previous winter survived the summer and replenished the perennial ice cover. That was the smallest replenishment seen in the study. As a result, perennial ice coverage in January 2006 was about 14 percent smaller than the previous January.
