In the paper, Columbia University geoscientist Wally Broecker calculated how much carbon dioxide would accumulate in the atmosphere in the coming 35 years, and how temperatures consequently would rise. His numbers have proven almost dead-on correct. Meanwhile, other powerful evidence poured in over those decades, showing the “greenhouse effect’’ is real and is happening. And yet resistance to the idea among many in the U.S. appears to have hardened.
What’s going on?
“The desire to disbelieve deepens as the scale of the threat grows,’’ concludes economist-ethicist Clive Hamilton.
He and others who track what they call “denialism’’ find that its nature is changing in America, last redoubt of climate naysayers. It has taken on a more partisan, ideological tone. Polls find a widening Republican-Democratic gap on climate. Republican presidential candidate Rick Perry even accuses climate scientists of lying for money. Global warming looms as a debatable question in yet another U.S. election campaign.
From his big-windowed office overlooking the wooded campus of the Lamont-Doherty Earth Observatory in Palisades, N.Y., Broecker has observed this deepening of the desire to disbelieve.
“The opposition by the Republicans has gotten stronger and stronger,’’ the 79-year-old “grandfather of climate science’’ said in an interview. “But, of course, the push by the Democrats has become stronger and stronger, and as it has become a more important issue, it has become more polarized.’’
The solution: “Eventually it’ll become damned clear that the Earth is warming and the warming is beyond anything we have experienced in millions of years, and people will have to admit…’’ He stopped and laughed.
“Well, I suppose they could say God is burning us up.’’
