THE PHOTOGRAPHIC DOCUMENTATION OF CLIMATE CHANGE
OCEAN INUNDATES ISLAND NATIONS
Sea level rise is the greatest problem. Tuvalu's highest elevation is 4.6 meters -- 15 feet -- but most of it is no more than a meter above the sea. Several times each year the regular lunar cycle of tides, riding on the ever higher mean sea level, brings the Pacific sloshing over onto roads and into neighborhoods. In the center of the larger islands the sea floods out of old barrow pits and even squirts up out of the coral bedrock. Puddles bubble up that eventually cover part of the airport on the main island of Funafuti and inundate homes that are not along the ocean.

ECOSYSTEM SHIFT UP MOUNTAINSIDES
Pushing the Boundaries of Life: Temperate Zone
Alpine meadow and fell-field ecosystems are changing under atmospheric warming. On this site at 3000 meters in the Austrian Alps, Botanist Harald Pauli and researchers are finding plant species increasing and decreasing at different rates over a 10 year period. Essentially, the familiar alpine wildflower fields are being fragmented and rearranged. This is especially dangerous for plants forced to move upwards where there is just rock and ice, says Pauli. "We are running into a really serious loss of biodiversity." The 380 sites here were established in 1994 by Georg Grabherr, Pauli and others at the University of Vienna. This alpine research idea has expanded world wide into GLORIA - the "Global Observation Research Initiative in Alpine Environments."
The glaciers behind the scientists are an even more visible sign of global warming, and have receded many meters per year recently.
POLAR BEARS THREATENED BY RECORD THAW ACROSS THE ARCTIC
Polar Bear Listed in Endangered Species Act, but U.S. Government Limits Its Protection
The polar bear was officially listed as threatened under the U.S. endangered species act (ESA) on May 14, 2008. This the first creature brought under the act's protection for habitat loss that is linked to global warming. The official reason given was loss of Arctic sea ice and predictions that the ice will continue to decrease. Although global warming has been identified by most atmospheric and polar scientists as the main reason for Arctic warming and melting of sea ice, the U.S. Interior Department did not use this as a reason and clearly signaled it would not apply the law to greenhouse gas emissions.
Dirk Kempthorne, Interior Secretary, specifically said the listing would not prevent any sea ice from melting and that he would "make certain the ESA isn't abused to make global warming policies." This despite clear language in the ESA to control any activity causing harm to a listed species and requiring government agencies specifically not to jeopardize species by their actions. The wording of the listing document appears to be an attempt of the government to list the bear due to clear evidence of shrinking habitat yet not take all the steps to limit the loss. It seems analogous to President Bush's notorious "signing statements" limiting his acceptance of a Congressional law.
This could set up another court challenge by NGOs like the Center for Biological Diversity which originally brought the proposal and took the Interior Dept to court twice to get action.
"Threatened" under the ESA means a plant or animal may soon become endangered (at immediate risk of going extinct) if actions are not taken to protect it and its habitat.
