Lonnie Thompson, the country's leading paleoclimatologist, has been studying glacial ice for decades to better understand the impacts of climate change. He has found evidence that the global warming of the past half-century is now outside the range of climate variability for several millennia, if not longer.
Climate change is here, he says, and we have no choice but to act. "We tend to be at our best when we are faced with a problem, and we have no other choice except to deal with that problem." While Thomspon believes it's not too late, he also recognizes that it will take international cooperation at every level to change our course.
