Challenges to the unproven notion that human-driven, carbon-dioxide emissions are causing the world to go to hell in a handbasket appear to be on the increase.
According to surprising new research from the University of Waterloo in Ontario, chlorofluorocarbons (CFCs) are responsible for global warming since the 1970s, not carbon dioxide.
And researchers at Oxford University say the climate is less sensitive to carbon emissions than had been believed.
Daily Telegraph reporter Tom Chivers says the new U.K. findings may bolster the argument of those who argue there are better responses than making "grandiose pledges to cut emissions."
Chivers quotes Prof. Bjorn Lomborg, economist and high-profile author of The Skeptical Environmentalist, as saying rich countries are in a better position to deal with climate-change problems than poor ones are. So it's crucial to foster economic growth.
