Letter to the Editor - Saturday, October 12: More hot air

VIV Forbes (Carbon dioxide okay, DEX, October 9) must surely be in the running for a Nobel Prize since she knows better than 97% of the world's accredited climate scientists. But until her award comes through I'll stick with the established science.

Richard Somerville, professor emeritus and research professor at Scripps Institution of Oceanography, University of California San Diego reminds us: "The greenhouse effect is well understood. It is as real as gravity. The foundations of the science are more than 150 years old. Carbon dioxide in the atmosphere traps heat. We know carbon dioxide is increasing because we measure it. We know the increase is due to human activities like burning fossil fuels because we can analyse the chemical evidence for that."

To say that carbon dioxide does not contribute to global warming is not only fatuous, it is dangerous.
