SAN FRANCISCO—While the evidence is clear that human-caused global warming is occurring and is a threat to many humans and other organisms on the planet, many Americans have been slow to buy the whole argument.
Yesterday at its annual meeting here, the American Association for the Advancement of Science, the largest science organization in the world, issued a consensus statement that "global climate change caused by human activities is occurring now and is a growing threat to society,'' Earlier this month the Intergovernmental Panel in Climate Change issued a statement that global warming will "continue for centuries" and is "very likely caused by man."
While these statement may have changed public opinion in recent weeks, last year a joint poll between ABC News, Time, Stanford University and Ohio State University found that only 3 in 10 Americans believed that global warming is caused by humans. Less than 40 percent of the nation’s public called global warming is an immediate and serious problem.
You’ve probably heard about the global warming song and dance: rising temperatures, melting ice caps and rising sea levels in the near future. But Earth’s changing climate is already wreaking havoc in some very weird ways. So gird yourself for such strange effects as savage wildfires, disappearing lakes, and freak allergies.
