Glacier park complex on the U.S.-Canada border. Several major glaciers there have shrunk by half or more in recent decades. On the U.S. side of the border, the number of glaciers in Glacier National Park has dropped from 150 in 1850 to 35 today.
Wildlife is also feeling the heat. A 2004 study by the Wildlife Society, a 9,000-member group of wildlife professionals, found that global warming is affecting many North American species and could cause major shifts in ecosystems. The group concluded that caribou, polar bears, migratory songbirds and other species have already responded to climate change by shifting habitat, altering their breeding patterns or changing their migration routes. •
Finally, stronger storms like Hurricane Katrina in recent years - may be partially explained by global warming. Researchers have found that both the intensity and number of category 4 and 5 storms have greatly increased in the past 35 years, and have linked that phenomenon to warming ocean temperatures.
