Matt Ridley wrote an editorial in the weekend edition of the Wall Street Journal discussing how cause and effect are often confused.
What was of specific interest to me was Ridley's noting,
"When in 1999 Antarctic ice cores revealed carbon-dioxide concentrations and temperature marching in lockstep over 400,000 years, many- including me- found this a convincing argument for attributing past climate change to carbon dioxide. Then four years later came clear evidence from finer-grained analysis of ice cores that temperature changes preceded carbon-dioxide changes by at least 800 years."
Yet we continue to hear about global warming due to carbon-dioxide. Even the EPA is currently treating C02 as damaging to the environment, despite this evidence to the contrary.
