How Many Scientists Say That Mankind Is Affecting Global Warming?

But now a study of all research papers between 2004 and 2007 indicates only seven percent give an explicit endorsement of that so-called consensus. Forty-five percent give an implicit endorsement. But 48 percent of the papers are classified as neutral — neither accepting nor rejecting the hypothesis. And only one of the 528 papers reviewed makes any reference to climate change leading to catastrophic results.

Earlier this year the U.N.'s Intergovernmental Panel on Climate Change said it was "90 percent likely" that man was having an impact on global temperatures. And dailytech.com
reports an analysis of scientific papers in 2004 concluded that a
majority of researchers supported what it called the "consensus view"
that humans were effecting climate change.

Another case of environmentalists fighting among themselves. It concerns the new global warming movie — "The 11th Hour" — produced and co-written by actor and activist Leonardo DiCaprio.

The
film contends that cutting fewer trees and using less wood would be
beneficial to the environment. But Greenpeace co-founder Patrick Moore
writes on Canada.com the opposite is true — that using more wood, and
growing more trees — is a better plan. Moore says trees absorb carbon
dioxide — convert it to wood — and that wood retains the CO2 when it is
cut down. He says trees release the carbon dioxide only when they rot
or burn.

Moore says increased use of wood could
lead to less use of concrete, steel, and plastic — which produce large
amounts of CO2 during manufacturing.
