Although the consequences of global warming are painfully vivid, some scholars still question whether it requires urgent action. In January, a group of scientists, including those from the United States, Australia, France and the Netherlands, summarized reasons for their skepticism and opposition to findings of the UN’s Intergovernmental Panel on Climate Change. They insist that evidence is lacking to show the world is warming and maintain that delaying action on climate change for 50 years would impose no serious economic consequences and could even offer benefits to less developed nations as they catch up with developed economies. The author responds to the essay, pointing out faults in the skeptics’ review of climate modeling, temperature trends and basic cost-benefit analysis and countering that taking steps to slow climate change won’t result in economic catastrophe.
