Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic according to a new study to be published in the Sept. 22, 2005, issue of Science Express. The resulting atmospheric heating in the region of northern Alaska is equivalent to...Shrinking ponds signal warmer, dryer Alaska
A first-of-its kind analysis of fifty years of remotely sensed imagery from the 1950s to 2002 shows a dramatic reduction in the size and number of more than 10,000 ponds in Alaska. The analysis, by University of Alaska Fairbanks scientists and published this week in the Journal of Geophysical Research, indicates that these landscape-level changes in arctic ponds are associated with recent climate...How fish species suffer as a result of warmer waters
Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. This applies also to fish populations. Previous studies demonstrating a link between global warming and declining fish stocks were based entirely on statistical data. However, in order to estimate future changes, it is essential to develop a deeper understanding of t...Healthy coral reefs hit hard by warmer temperatures
Coral disease outbreaks have struck the healthiest sections of Australia's Great Barrier Reef, where for the first time researchers have conclusively linked disease severity and ocean temperature. Close living quarters among coral may make it easy for infection to spread, researchers have found. "With this study, speculation about the impacts of global warming on the spread of infectious d...Skin Cancer Rates Soar In Warmer Regions Of UK
Experts are voicing their concerns as cases of the deadly melanoma continue to rise over Britain and especially in sunny West Country regions like Cornwall . According to dermatologists, though the summers get increasingly hot each year, Britons are still not aware of how to protect themselves from the deadly rays. Official figures declare malignant melanoma to be the UK's f...DNA Sample Suggests Greenland was Much Warmer During Last Ice Age
Ancient DNA samples recovered from the bottom of a two-kilometre thick ice sheet in Greenland has shown that the island was much warmer at some point during the last Ice Age than previously believed . The DNA came from the trees, plants and insects of a boreal forest estimated to be between 450,000 and 900,000 years old. Previously, the youngest evidence of a boreal forest in Greenl...Astotherm Plus Blood and Fluid Warmers
