Hpoeful note on climate change
It says warming can be limited at a reasonable price
Just as important, existing technology will do most of the job, as long as policymakers make sure it is quickly adopted. And average citizens can make valuable contributions by making small lifestyle changes without waiting for governments to act.
But skeptics, including the Bush administration, said that the most stringent recommended measures could strain the world economy. And others doubted that the worst polluting nations would have much incentive to cooperate.
The panel's latest report, released Friday in Bangkok, "addresses a fundamental concern of Americans: Can we do something about this?" said Peter Altman, a climate expert at the National Environmental Trust. "The answer is a resounding yes."
Just as important, dramatically cutting greenhouse gas emissions to levels scientists believe would stem increases in warming would cost nations at most 0.12 percent of economic growth each year through 2030, scientists said.
"The bottom line is all it takes to beat this problem is the political will to put the solutions in hand to work and to invest in clean energy solutions for the future," Altman said. "To do this at about a tenth of a percent of GDP per year is a very low-cost investment for something with tremendous payoff."
Bush administration officials, who along with representatives of 120 other countries approved the report's policy summary before its release this week, praised it for highlighting "the importance of deploying a portfolio of clean energy technologies." But they said that trying to cut greenhouse gas emissions by 50 to 85 percent by 2050, in line with the report's most ambitious scenarios, would have economic consequences.
The 2,000 scientists who contributed to the report, however, concluded that stabilizing greenhouse gas emissions at near-current levels was not only possible but would cost no more than 3 percent of the world's income between now and 2030.
