This month’s Copenhagen talks focused on the leading climate change culprit: carbon dioxide. But reversing global temperature increases by reducing carbon emissions will take many decades, if not centuries. Even if the largest cuts in CO2 contemplated in Copenhagen are implemented, it simply will not reverse the melting of ice already occurring in the most sensitive areas, including the rapid disappearance of glaciers in Tibet, the Arctic and Latin America.
So what can we do to effectively buffer global warming? The most obvious strategy is to make an all-out effort to reduce emissions of methane.
Yet global discussions about climate and policies to date have not focused on methane. Methane is formally in the “basket” of six gases targeted by the 1997 Kyoto Protocol. But its value is counted as if it has the same lifetime as carbon dioxide.
Funded by governments and private foundations, a Global Methane Fund with only $100 million to $200 million could leverage tens of billions of dollars for other projects, which will have a quick and measurable cooling effect in the Arctic and elsewhere. Scientific studies, such as the EPA’s June 2006 report, “Global Mitigation of Non-CO2 Greenhouse Gases,” conservatively indicate that we could eliminate 1.3 gigatons of annual CO2 equivalent emissions—that’s half the U.S. power industry’s emissions—just by targeting landfills, coal mines, and oil and gas leaks.
Such a fund would benefit melting glaciers in the Arctic, and in the Andean and Himalayan mountains. And it would demonstrate to the world that we can do something to quickly slow climate change.
We need to get moving to cool the planet’s temperature. Methane is the most effective place for us to start.
