Katherine Hayhoe of Texas Tech University says the extreme weather, ranging from deep snowfalls to monster floods, seen recently in the United States is evidence of the human-caused, climate-change fueled "new normal" for weather.
"It´s a new normal and I really do think that ´global weirding´ is the best way to describe what we´re seeing," she told a panel of experts organized by the Union of Concerned Scientists. Also on hand was the Swiss Re reinsurance company.
"What we´re seeing is the new normal is constantly evolving," said Swiss Re´s Nikhil da Victoria Lobo. In the U.S., for example, an extended drought has been punctuated by an upsurge in massive rainstorms.
