| 696629 | 2008-08-12 01:41:00 | What a surprise!!! Climate change models may be inaccurate U.S. scientists say they've discovered some measures used in atmospheric science overlook important factors affecting climatic warming and cooling. The Arizona State University researchers led by Associate Professor Peter Crozier said their discovery could lead to more accurate forecasting of global-warming activity. Crozier, along with Ira Fulton and Duncan Alexander, studied nanoscale atmospheric aerosols called brown carbons, which they said are largely being ignored in climate computer models in favor of carbon dioxide and other greenhouse gases. But the researchers say there are other atmospheric components that can also contribute to climate change -- including carbonaceous and sulfate particles from combustion of fossil fuels and biomass, salts from oceans and dust from deserts. They said brown carbons from combustion processes are the least understood of all aerosol components, but their effect is complex because it both cools the Earth's surface and warms the atmosphere. "Because of the large uncertainty we have in the radiative forcing of aerosols, there is a corresponding large uncertainty in the degree of radiative forcing overall," Crozier said. "This introduces a large uncertainty in the degree of warming predicted by climate change models." The research appears in the Aug. 8 issue of Science magazine. Makes you wonder what else they don't know... |

| 696632 | 2008-08-12 16:29:00 | I have a weather report sniffer and find some interesting stats from time-to-time. Here's a sample of the date today (AUG 12th) of some of the weather anomalies that happened in the recent and sometimes distant past: 1778 A Rhode Island hurricane prevented an impending British-French sea battle, and caused extensive damage over southeast New England. 1933 The temperature at Greenland Ranch in Death Valley CA hit 127 degrees to establish a U.S. record for the month of August. 1936 The temperature at Seymour TX hit 120 degrees to establish a state record. 1955 During the second week of August hurricanes Connie and Diane produced as much as 19 inches of rain in the northeastern U.S. forcing rivers from Virginia to Massachusetts into a high flood. Westfield MA was deluged with 18.15 inches of rain in 24 hours, and at Woonsocket RI the Blackstone River swelled from seventy feet in width to a mile and a half. Connecticut and the Delaware Valley were hardest hit. Total damage in New England was 800 million dollars, and flooding claimed 187 lives. 1987 Early afternoon thunderstorms in Arizona produced 3.90 inches of rain in ninety minutes at Walnut National Monument (located east of Flagstaff), along with three inches of pea size hail, which had to be plowed off the roads. 1988 Fifteen cities in the northeastern U.S. reported record high temperatures for the date. Youngstown OH reported twenty-six days of 90 degree weather for the year, a total equal to that for the entire decade of the 1970s. 1989 Thunderstorms were scattered across nearly every state in the Union by late in the day. Thunderstorms produced wind gusts to 75 mph at Fergus Falls MN, and golf ball size hail and wind gusts to 60 mph at Black Creek WI. In the Chicago area, seven persons at a forest preserve in North Riverside were injured by lightning. I don' really see a trend or pattern here either. |
