Global Warming and Hot Air
By Robert J. SamuelsonYou could be excused for thinking that we'll soon do something serious about global warming. Last Friday, the Intergovernmental Panel on Climate Change (IPCC) -- an international group of scientists -- concluded that, to a 90 percent probability, human activity is warming the Earth. Earlier, Democratic congressional leaders made global warming legislation a top priority; and 10 big U.S. companies (including General Electric and DuPont) endorsed federal regulation. Strong action seems at hand. Don't be fooled. The dirty secret about global warming is this: We have no solution. About 80 percent of the world's energy comes from fossil fuels (coal, oil, natural gas), the main sources of man-made greenhouse gases. Energy use sustains economic growth, which -- in all modern societies -- buttresses political and social stability. Until we can replace fossil fuels or find practical ways to capture their emissions, governments will not sanction the deep energy cuts that would truly affect global warming. Considering this reality, you should treat the pious exhortations to "do something" with skepticism, disbelief or contempt. These pronouncements are (take your pick) naive, self-interested, misinformed, stupid or dishonest. Politicians mainly want to be seen as reducing global warming. Companies want to polish their images and exploit markets created by new environmental regulations. As for editorialists and pundits, there's no explanation except superficiality or herd behavior.
