整个物理界都认为“变暖”是无可争议的。

只是原因的不同才是AGW 的区别。

如果连变暖变成可争议的,那才是大事了。

Ad-hoc Committee Examines APS Climate Change StatementEmail
Don Prosnitz & Philip W. Hammer

At the May 2009 meeting of the APS Council, a member of Council moved that the Council reconsider the APS statement on Climate Change that was passed in November, 2007. In particular, this Councilor said that he and approximately 50 current and former APS members with whom he has contact feel that the statement is questionable by its inflexible declaration that the evidence for global warming is “incontrovertible.” APS President Cherry Murray suggested, and it was approved by consensus, that the motion be tabled and that she appoint a high level ad hoc committee of respected senior scientists and charge them with reviewing the current APS Climate Change statement. The committee will make a recommendation as to whether or not the statement should be changed and suggest new wording if necessary. The committee will report its findings and recommendation to the APS President who will then convey these to the Council at its November 2009 meeting. After hearing the report from the ad hoc committee, Council will determine if any further action is required.

2007的宣言:
National Policy
07.1 CLIMATE CHANGE
(Adopted by Council on November 18, 2007)

Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate. Greenhouse gases include carbon dioxide as well as methane, nitrous oxide and other gases. They are emitted from fossil fuel combustion and a range of industrial and agricultural processes.

The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.

Because the complexity of the climate makes accurate prediction difficult, the APS urges an enhanced effort to understand the effects of human activity on the Earth’s climate, and to provide the technological options for meeting the climate challenge in the near and longer terms. The APS also urges governments, universities, national laboratories and its membership to support policies and actions that will reduce the emission of greenhouse gases.
