The North Pole Is Melting
German expedition on the icebreaker Polarstern has revealed that existing Arctic sea ice in the center of the ice cap is only about three feet (one meter) thick, 50 percent thinner than it was just six years ago. As a result, more melt water is mixing with the salty seawater and pulses of warmer Atlantic seawater have intruded into the Arctic Ocean.
"The sea ice cover this year has reached a new record low,"
"It's not just that we beat the old record, we annihilated it."
hours. Numerous contrails are formed in the vicinity of main air- traffic routes; due to additional
spreading effects contrails may contribute significantly to the total cloud cover. Continuous
observational methods are used to study the formation of contrails in the subarctic setting of
Fairbanks, Alaska. Since March of 2000 a contrail database has been established, which includes
contrail characteristics, Federal Aviation Administration flight data, and atmospheric measurements
derived from radiosonde ascents at Fairbanks International Airport. The contrail analysis is based on
all-sky digital camera imagery and direct observations of aircrafts.

September's Science: Shutdown of airlines aided contrail studies
Week of May 11, 2002; Vol. 161, No. 19 , p. 291
"Immediately after four hijacked airliners slammed into New York's World Trade Center, the Pentagon, and a field in southwestern Pennsylvania, the Federal Aviation Administration shut down all U.S. commercial air traffic for 3 days. The unprecedented grounding of airliners enabled airports to step up security measures. At the same time, scientists stepped up to a unique opportunity to study the influence of high-flying aircraft on Earth's climate."
the Pacific Northwest, the Midwest, and the Northeast�areas of the country typically blanketed with aircraft contrails in mid-September�showed the largest changes in diurnal temperature range, mostly from increased daytime high temperatures. This bolsters the argument that contrails can significantly affect climate
Sept. 12, individual cloud trails of high-flying military aircraft stand out clearly in a nearly cloud-free region west of Washington, D.C. In just a few hours, six contrails�each of which started out a few meters wide�spread to cover more than 20,000 square kilometers.
