The following are some key findings in a report issued Saturday by the United Nations Intergovernmental Panel on Climate Change:
• Global warming is "unequivocal." Temperatures have risen 1.3 degrees Fahrenheit in the last 100 years. Eleven of the last 12 years are among the warmest since 1850. Sea levels have gone up by an average seven-hundredths of an inch per year since 1961.
• About 20 percent to 30 percent of all plant and animal species face the risk of extinction if temperatures increase by 2.7 degrees Fahrenheit. If the thermometer rises by 6.3 degrees Fahrenheit, between 40 to 70 percent of species could disappear.
• Human activity is largely responsible for warming. Global emissions of greenhouse gases grew 70 percent from 1970 to 2004. The concentration of carbon dioxide in the atmosphere is far higher than the natural range over the last 650,000 years.
• Climate change will affect poor countries most, but will be felt everywhere. By 2020, 75 million to 250 million people in Africa will suffer water shortages, residents of Asia's large cities will be at great risk of river and coastal flooding, Europeans can expect extensive species loss, and North Americans will experience longer and hotter heat waves and greater competition for water.
• Extreme weather conditions will be more common. Tropical storms will be more frequent and intense. Heat waves and heavy rains will affect some areas, raising the risk of wildfires and the spread of diseases. Elsewhere, drought will degrade cropland and spoil the quality of water sources. Rising sea levels will increase flooding and salination of fresh water and threaten coastal cities.
• Even if greenhouse gases are stabilized, the Earth will keep warming and sea levels rising. More pollution could bring "abrupt and irreversible" changes, such as the loss of ice sheets in the poles, and a corresponding rise in sea levels by several yards.
_A wide array of tools exist, or will soon be available, to adapt to climate change and reduce its potential effects. One is to put a price on carbon emissions.
• By 2050, stabilizing emissions would slow the average annual global economic growth by less than 0.12 percent. The longer action is delayed, the more it will cost.
Recently someone was on the radio ... Beck? Saying that CO2 is only one molecule in a hundred thousand in the air, and that it would take some huge amount of emissions to increase that to two in a hundred thousand. Or was that two hundred thousand?
Does anybody know where any sources for this can be found?
~~ AGW™ ping~~
Does anybody know if they have ever actually released the original study from which they are drawing these conclusions?
Please see my post #43.
Damn Monk you got everybody in there BTW I see Islamic rage boy LOL!
Is that Palensteian woman right there on bottom
Yep.
The statement is correct for global temperatures. The NASA corrections were for U.S. temperatures.
See post 47.
Final two sentences of this paper: "During the 1990s, the observed thinning at the margins and the growth inland were both expected responses to climate warming. Our new results suggest that the processes of significant ice depletion at the margins, through melting and glacier acceleration, are beginning to dominate the interior growth as climate warming has continued."
You are correct, and also YOU should state that there are VERY FEW temperature stations with ACCURATE data from places other than EUROPE and the USA. Using inaccurate temperature data from other places skews results. Garbagein=Garbage out. Also, last Sothern Hemisphere winter showed largest recorded area of SEA ICE, and new Sat data is showing INCREASING mass of Antarctic ice, which MORE than offsets losses in Greenland.
As glaciers from Greenland to Kilimanjaro recede at record rates, the central ice cap of Antarctica has steadily grown for the past 11 years, partially offsetting rising seas due to global warming, researchers said Thursday.
The vast East Antarctic Ice Sheet ? a 2-mile-thick wasteland of ice larger than Australia, drier than the Sahara and as cold as a Martian spring ? increased in mass every year between 1992 and 2003 due to additional snowfall, an analysis of satellite radar measurements showed.
“It is an effect that has been predicted as a likely result of climate change,” said David Vaughan, an independent expert on the ice sheets at the British Antarctic Survey in Cambridge, England.
In a region known for the lowest temperatures on Earth, it normally is too cold to snow across the 2.7 million square miles of the ice sheet. Additional snowfall in east Antarctica is almost certainly due to warmer temperatures, four experts on Antarctica said.
“As the atmosphere warms, it should hold more moisture,” said climatologist Joseph McConnell at the Desert Research Institute in Reno, Nev., who helped conduct the study. “In East Antarctica, that means there should be more snowfall.”
The additional snowfall is enough to account for an extra 45 billion tons of water added to the ice sheet every year, about equal to the annual amount of water flowing into the ocean from the melting Greenland ice cap, researchers said Thursday in the online journal Science.
Shipboard temperature measurements are conducted worldwide, and this data covers about 70% of the world surface. The global temperatures are a combined land-sea temperature record. So, two questions: are shipboard temperature measurements indicated to be deficient compared to terrestrial stations? And why should Australia and New Zealand -- considered developed, affluent, "Western" nations -- have poorer temperature recordkeeping than the U.S. and Europe? (These are significant because they are important regions and land masses in the Southern Hemisphere, which has much less land surface compared to ocean surface than the Northern Hemisphere.)
Its a good practice to look for errors in data collection. Supposed errors have not yet been demonstrated to have a significant effect on the computed trends.
Also, last Sothern Hemisphere winter showed largest recorded area of SEA ICE, and new Sat data is showing INCREASING mass of Antarctic ice, which MORE than offsets losses in Greenland.
Two different environments. Melting of the Greenland ice sheet could cause instability and collapse there while Antarctica accretes.

Thanks for including this in your posting.
Were you the one who served the kool-aid to Al Gore?
Since you are the all-knowing scientist, I guess you have no problem with discounting the opinions of the scientists who doubt that man is causing the earth to warm.
The Golden Horseshoe Award: Jaworowski and the vast CO2 conspiracy
This should appear next to (or under) "Climate Change: Incorrect information on pre-industrial CO2".
I've been thinking that your list could be a very useful guide to the issue if properly augmented. Which would take time considering the length of the list. But it might be worthwhile.
What good is real data mixed with model results unless the real data is refusing to cooperate with a foregone conclusion?
One hundred years ago, ships typically lowered a bucket in the sea and then measured the temp once brought back onboard; how has the measurement technique changed since?
Just as I am not really a professor, cogitator is not a scientist; I’m beginning to think he is a CFL light bulb salesman.
You are welcome...The argument that man understands all the dynamics of climate, not to mention claiming a direct cause and effect between CO2 and tmeperature is crazy. Three years ago we were deluged with Al Gore claiming hurricanes were increasing and more powerful because of GW, and this year in the Atlantic basin figures to be a near record in terms of number of days with active hurricanes. Last year was low by historic standards as well.......you might want to read.......The Cold Truth about Greenland........http://www.cato.org/pub_display.php?pub_id=8285..........where scientists who disagree with the ‘Branch Algorians’...........Data from the United States’ National Climactic Data Center show that temperatures in Greenland for the last decade are hardly unusual when compared to temperatures for the last 100 years. The period from 1915 through 1965 — an entire half–century — was about two degrees warmer than it is today.
..........further they state...........
In 2000, Glen MacDonald and several coauthors published an eye–opening perspective on the climate history of the Eurasian arctic in the highly respected journal Quaternary Research (”quaternary” is the era of recent ice ages, beginning about 1.8 million years ago) in which they examined radiocarbon dates of old trees deposited in the tundra, far north of today’s northernmost trees. In that region, the tree line is generally over 100 miles south of the Arctic Ocean. But for much of the era from 3,000 to 9,000 years ago, the forest extended right to the sea.
Summer temperatures — the same ones that melt Greenland’s ice — are what determine the Northern treeline. MacDonald had to conclude that “Over much of northern Eurasia [during that period], summers may have been 4.5 to 12.6°F warmer than today.”
Moreover, they wrote that the only way this could occur was if there was a massive incursion of warm (Gulf Stream) water into the Arctic Ocean. How does such water get there? By passing between Greenland and Europe. It’s the only way.
So Greenland had to have been much warmer than it is now for six millennia. Again, where are the records of unprecedented rises in sea level? There aren’t any, because there wasn’t any. Sea levels rose to roughly where they are today.
Nah, something much bigger.
