Scientific Research Connects the Dots
Hurricane Intensity Influenced by Global Warming
Major Global Warming Research Findings of Past 12 Months
2005 was one of the worst years for natural disasters in the United States, setting an unprecedented cost of over $121 billion in damage, with over 1460 deaths. Since the day that Hurricane Katrina devastated the Gulf coast, scientists have uncovered sobering evidence that these natural disasters are becoming more common and severe.
· Global Warming is causing stronger and more frequent hurricanes:
"We conclude that global data indicate a 30-year trend toward more frequent and intense hurricanes, corroborated by the results of the recent regional
assessment. This trend is not inconsistent with recent climate model simulations
that a doubling of CO2 may increase the frequency of the most intense cyclones."
- P. J. Webster et al, "Changes in Tropical Cyclone Number, Duration, and Intensity in a Warming Environment," Science, 16 Sept 2005
"Our observational results based on long term trends of SST [sea surface
temperature] reveal that the anomaly reached a record 0.8 °C in the Gulf of
Mexico in August 2005 as compared to previous years and may have been
responsible for the intensification of the devastating Hurricane Katrina
into a category 5 hurricane..."

· First 6 months of 2006 are hottest on record:
"The average temperature for the continental United States from January through June 2006 was the warmest first half of any year since records began in 1895,
according to scientists at NOAA's National Climatic Data Center in Asheville,

· Hotter temperatures mean longer wildfire seasons:
"The average season-length [of wildfires] (the time between the reported first wildfire discovery date and the last wildfire control date) increased by 78 days(64%), comparing 1970-86 to 1987-03."

· Global Warming is happening now:
"Recent warming coincides with rapid growth of human-made greenhouse gases. […] Global warming is now 0.6°C in the past three decades and 0.8°C in the past century. It is no longer correct to say that 'most global warming occurred

· Antarctica ice sheet decreasing by 20 cubic miles or more each year:
"We found that the mass of the ice sheet decreased significantly, at a rate of 152 ± 80 cubic kilometers of ice per year [about 37 ± 20 cubic miles per year],which is equivalent to 0.4 ± 0.2 millimeters of global sea-level rise per year."
-Isabella Velicogna and John Wahr, "Measurements of Time-Variable Gravity Show Mass Loss in Antarctica," Science, 2 March 2006
Geophysicists Isabella Velicogna and John Wahr of the University of Colorado,Boulder, reported in Geophysical Research Letters how … between 2002 and 2004, GRACE [the satellite] found a loss of about 82 cubic kilometers [about 20 cubic miles] of ice per year."
- Richard A. Kerr, "A Worrying Trend of Less Ice, Higher Seas," Science, 24 March 2006
· Greenland's glaciers are melting by 22 cubic miles or more each year:
"Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year [about 22 to 53 cubic miles per year]. As more glaciers accelerate farther north, the contribution of Greenland to sea-level rise will continue to increase. […] Glacier acceleration in the east probably resulted from climate warming."
- Eric Rignot and Pannir Kanagaratnam, "Changes in the Velocity Structure of the Greenland Ice Sheet," Science, 17 Feb 2006
"The total melt extent of the ice sheet, experiencing at least 1 melt day between April 1 - September 25 shows a record extent in 2005 for the 27-year
long time PM data set. The 2005 melt extent exceeds the previous record of

· Greenhouse pollution levels are larger than ever:
"The concentration of carbon dioxide in the atmosphere climbed to a record 381 parts per million last year… The reading was up 2.6 parts per million, according to preliminary calculations, David J. Hofmann of the Office of Atmospheric Research at the National Oceanic and Atmospheric Administration said Tuesday."
