Want more evidence of Global Warming?
How about the flawed research evidence of the dissenters whom Bush relied on to push his anti-environment bullshit agenda?:

| August 12, 2005 Errors Cited in Assessing Climate Data By ANDREW C. REVKIN Some scientists who question whether human-caused global warming poses a threat have long pointed to records that showed the atmosphere's lowest layer, the troposphere, had not warmed over the last two decades and had cooled in the tropics. Now two independent studies have found errors in the complicated calculations used to generate the old temperature records, which involved stitching together data from thousands of weather balloons lofted around the world and a series of short-lived weather satellites. A third study shows that when the errors are taken into account, the troposphere actually got warmer. Moreover, that warming trend largely agrees with the warmer surface temperatures that have been recorded and conforms to predictions in recent computer models. The three papers were published yesterday in the online edition of the journal Science. The scientists who developed the original troposphere temperature records from satellite data, John R. Christy and Roy W. Spencer of the University of Alabama in Huntsville, conceded yesterday that they had made a mistake but said that their revised calculations still produced a warming rate too small to be a concern. "Our view hasn't changed," Dr. Christy said. "We still have this modest warming." Other climate experts, however, said that the new studies were very significant, effectively resolving a puzzle that had been used by opponents of curbs on heat-trapping greenhouse gases. �These papers should lay to rest once and for all the claims by John Christy and other global warming skeptics that a disagreement between tropospheric and surface temperature trends means that there are problems with surface temperature records or with climate models,� said Alan Robock, a meteorologist at Rutgers University. The findings will be featured in a report on temperature trends in the lower atmosphere that is the first product to emerge from the Bush administration's 10-year program intended to resolve uncertainties in climate science. Several scientists involved in the new studies said that the government climate program, by forcing everyone involved to meet five times, had helped generate the new findings. "It felt like a boxing ring on occasion," said Peter W. Thorne, an expert on the weather balloon data at the Hadley Center for Climate Prediction and Research in Britain and an author of one of the studies. Temperatures at thousands of places across the surface of the earth have been measured for generations. But far fewer measurements have been made of temperatures in the air from the surface through the troposphere, which extends up about five miles. Until recently Dr. Christy and Dr. Spencer were the only scientists who had plowed through vast volumes of data from weather satellites to see if they could indirectly deduce the temperature of several layers within the troposphere. They and other scientists have also tried to analyze temperature readings gathered by some 700 weather balloons lofted twice a day around the world. But each of those efforts has been fraught with complexities and uncertainties. The satellites' orbits shift and sink over time, their instruments are affected by sunlight and darkness, and data from a succession of satellites has to be calibrated to account for eccentricities of sensitive instruments. Starting around 2001, the satellite data and methods of Dr. Christy and Dr. Spencer were re-examined by Carl A. Mears and Frank J. Wentz, scientists at Remote Sensing Systems, a company in Santa Rosa, Calif., that does satellite data analysis for NASA. They and several other teams have since found more significant warming trends than the original estimate. But the new paper, by Dr. Mears and Dr. Wentz, identifies a fresh error in the original calculations that, more firmly than ever, showed warming in the troposphere, particularly in the tropics. The error, in a calculation used to adjust for the drift of the satellites, was disclosed to the University of Alabama scientists at one of the government-run meetings this year, Dr. Christy said. The new analysis of data from weather balloons examined just one possible source of error, the direct heating of the instruments by the sun. It found that when data were examined in a way that accounted for that effect, the temperature record produced a warming, particularly in the tropics, again putting the data in line with theory. "Things being debated now are details about the models," said Steven Sherwood, the lead author of the paper on the balloon data and an atmospheric physicist at Yale. "Nobody is debating any more that significant climate changes are coming." http://www.nytimes.com/2005/08/12/s...imate.long.html |

what i'm seeing in the news about sharks, coyote, bears, polar bears, plankton, and other really strange animal behavior makes me think its somehow all related. but then i look at the pirate graph and wonder if its just coincidence. i dont think so but thats just me

Boost to CO2 mass extinction idea
By Helen Briggs
BBC News science reporter
A computer simulation of the Earth's climate 250 million years ago suggests that global warming triggered the so-called "great dying".
A dramatic rise in carbon dioxide caused temperatures to soar to 10 to 30 degrees Celsius higher than today, say US researchers.
The warming had a profound impact on the oceans, cutting off oxygen to the lower depths and extinguishing most lifeforms, they write in the latest issue of Geology.
The research adds to the growing body of evidence that higher temperatures, rather than a giant space rock hitting the planet, led to the greatest mass extinction in history.
Prehistoric extinction
The extinction, at the end of the Permian Period and the beginning of the Triassic, has puzzled scientists for many years.
Some 95% of lifeforms in the oceans became extinct, along with about three-quarters of land species.
Many possible reasons for this catastrophic event have been proposed - including impacts, volcanism, climate change and glaciation. Hard evidence, however, has been difficult to find.
The latest data from scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, supports the view that extensive volcanic activity over the course of hundreds of thousands of years released large amounts of carbon dioxide and sulphur dioxide into the air, gradually warming up the planet.
Deep impact
The NCAR team used a research tool known as the Community Climate System Model (CSSM) which looks at the combined effects of atmospheric temperatures, ocean temperatures and currents.
PERMO-TRIASSIC EXTINCTION
The greatest of all Earth's mass extinctions occurred about 250 million years ago
About 95% of marine species and three-quarters of all families on the Pangean (above) landmass perished
Rocks from the end of the Permian period can be seen today in places such as China, Italy and Pakistan
Chief suspects include sea-level fluctuations, volcanic activity, space impacts and melting methane-ice in sea sediments
Their work indicates that temperatures in higher latitudes rose so much that the oceans warmed to a depth of about 3,000m (10,000ft).
This interfered with the circulation process that takes colder water, carrying oxygen and nutrients, into lower levels. The water became depleted of oxygen and was unable to support marine life.
"The implication of our study is that elevated CO2 is sufficient to lead to inhospitable conditions for marine life and excessively high temperatures over land would contribute to the demise of terrestrial life," Jeffrey Kiehl and colleagues write in Geology.
Until recently, computer models of past climate have been hampered by the difficulty of accounting for complex interactions between the various components of the Earth's climate system
Professor Paul Wignall, of the University of Leeds, UK, who studies the Permian-Triassic boundary, says the models have not been sophisticated enough to recreate such "lethal super-greenhouse climates".
"I suspect many in the modelling community have been sceptical about just how bad conditions were 250 million years ago, even though the evidence is in the rocks; but now the latest climate system modelling is able to replicate climatic conditions that came close to destroying life on Earth," he told the BBC News website.

Ok, this made me go into an uncontrollable laughter

Other than a lot of hoopla with little or no evidence of direct causation I perfer to see the light side...

"There's a lot of differing data [about global warming], but as far as I can gather, over the last hundred years the temperature on this planet has gone up 1.8 degrees. Am I the only one who finds that amazingly stable? I could go back to my hotel room tonight and futz with the thermostat for three to four hours. I could not detect that difference." - Dennis Miller |

Global warming's �10 trillion cost ALLISTER HEATH PREVENTING global warming would cost the world economy a devastating $18 trillion (�9.9 trillion) even under the most conservative assumptions, a report out this week will warn. The cost, equivalent to 45 per cent of world gross domestic product for a year, is much greater than any conceivable benefit, according to the report from top economic consultants Lombard Street Research. Charles Dumas, author of the study, said: "This is orders of magnitude greater than the cost of dealing with higher sea levels and freak weather, net of land gains in Canada, Siberia and other cold areas in thousands of square miles." The costing is based on the assumption that cutting global warming would require reducing the world's consumption of oil and energy, and that this in turn would reduce global growth by 0.5 percentage points a year for five years. The $18 trillion figure is the net present value of that reduction. Growth is then assumed to get back to its long-term rate, an estimate which the author says is very conservative and probably hugely underplays the true cost of attempting to deal with climate change. During the past 20 years, world oil consumption has averaged approximately 70 million barrels a day (mpdb). In 2005, consumption is expected to be just under 84 mbpd, 20 per cent up. So to have any measurable impact on global warming, oil consumption would have to be cut hugely and quickly, Dumas said. Two thirds of oil demand growth is in developing Asia, as China, where dirty coal is the chief form of fuel and greenhouse gas emission, India and the Pacific Tigers are taking over much of the world's manufacturing and construction output. The report warns: "Either this Asian release of record numbers of people from poverty - one of the great achievements of the past 20 years - will have to be reversed, or cuts in oil usage will have to be extremely sharp in developed economies". No serious economic cost-benefit analysis will ever recommend taking the radical steps required to prevent global warming, the Lombard Street Research study says. Dumas said: "The proposed Kyoto treaty limits would in no way prevent global warming. In reality, nobody seriously proposes a cure for global warming, because adequate measures would cause economic catastrophe and probably world war." |
