Natural Forces, Not Man, Causing Global Warming, Scientist Says

Natural forces, not human activity, are primarily responsible for any global warming taking place, prominent atmospheric and space physicist Fred Singer declared Monday at the Heartland Institute's 2008 International Conference on Climate Change

the preponderance of scientific evidence about natural forces causing global warming is so great that the issue is settled,

"The science is settled in the sense that we have evidence that most of the climate change taking place today is caused by natural forces and not by human activity," Singer

Since natural variability is responsible for climate change, it logically follows that warming and cooling periods are unstoppable and that carbon dioxide is not a pollutant,
