The Earth has been getting warmer -- but how much of that heat is due to greenhouse gas emissions and how much is due to natural causes?All this has happened before, and it will happen again. Earth's climate is cyclical, with or without SUV's.
A leaked report by a United Nations’ group dedicated to climate studies says that heat from the sun may play a larger role than previously thought.
“[Results] do suggest the possibility of a much larger impact of solar variations on the stratosphere than previously thought, and some studies have suggested that this may lead to significant regional impacts on climate,” reads a draft copy of a major, upcoming report from the U.N.’s Intergovernmental Panel on Climate Change (IPCC)...
“Climate science has the problem of trying to explain why we are now in our 17th year without a significant warming trend. As a result, you are seeing many forecasts of warming for this century being ratcheted down,” he said.
Why, then, do the True Believers cling to their global warming with religious fervor? I point out the reasons in this post, among others.
