Skeptics From Around the Globe-APS Letter

An Open Letter to the Council of the American Physical Society

As physicists who are familiar with the science issues, and as current and past members of the American Physical Society, we the undersigned urge the Council to revise its current statement on climate change as follows, so as to more accurately represent the current state of the science:

Greenhouse gas emissions, such as carbon dioxide, methane, and nitrous oxide, accompany human industrial and agricultural activity. While substantial concern has been expressed that emissions may cause significant climate change, measured or reconstructed temperature records indicate that 20th -21st century changes are neither exceptional nor persistent, and the historical and geological records show many periods warmer than today. In addition, there is an extensive scientific literature that examines beneficial effects of increased levels of carbon dioxide for both plants and animals.

Studies of a variety of natural processes, including ocean cycles and solar variability, indicate that they can account for variations in the Earth’s climate on the time scale of decades and centuries. Current climate models appear insufficiently reliable to properly account for natural and anthropogenic contributions to past climate change, much less project future climate.

The APS supports an objective scientific effort to understand the effects of all processes – natural and human -- on the Earth’s climate and the biosphere’s response to climate change, and promotes technological options for meeting challenges of future climate changes, regardless of cause.

Skeptics From Around the Globe-Manhattan Declaration

ITALY
Among the over 1000 Signers of the Manhattan Declaration on Climate Change

"Global Warming" is not a crisis

Hereby declare:

That current plans to restrict anthropogenic CO2 emissions are a dangerous misallocation of intellectual capital and resources that should be dedicated to solving humanity’s real and serious problems.

That there is no convincing evidence that CO2 emissions from modern industrial activity has in the past, is now, or will in the future cause catastrophic climate change.

That attempts by governments to inflict taxes and costly regulations on industry and individual citizens with the aim of reducing emissions of CO2 will pointlessly curtail the prosperity of the West and progress of developing nations without affecting climate.

That adaptation as needed is massively more cost-effective than any attempted mitigation, and that a focus on such mitigation will divert the attention and resources of governments away from addressing the real problems of their peoples.

That human-caused climate change is not a global crisis.

Now, therefore, we recommend –

That world leaders reject the views expressed by the United Nations Intergovernmental Panel on Climate Change as well as popular, but misguided works such as “An Inconvenient Truth”.

That all taxes, regulations, and other interventions intended to reduce emissions of CO2 be abandoned forthwith.

Forese Carlo Wezel Professor of Stratigraphy at Urbino University (Italy).

"It follows that scientists worldwide have not only failed to understand anything, but the hoaxer and dreamers: the anthropogenic global warming is the most colossal forgery of the century....the biggest sham of the last 15 years...the conjecture of anthropogenic global warming should be regarded as pure speculation today- phiscally disproved by the real facts"

“I think that climatic changes have natural causes according to geological data…I am very glad to sign the U.S. Senate’s report of scientists against the theory of man-made global warming....

.....It is 'obvious that to continue to give the responsibility of climate change to human activities is scientifically incorrect and misleading, and at least suspect.”

thermodynamic models we used suggest that the Sun is influencing climate significantly more than the IPCC report claims. If climate is as sensitive to solar changes as the above phenomenological findings suggest, the current anthropogenic contribution to global warming is significantly overestimated.

We estimate that the Sun could account for as much as 69% of the increase in Earth’s average temperature, depending on the TSI reconstruction used.5 Furthermore, if the Sun does cool off, as some solar forecasts predict will happen over the next few decades, that cooling could stabilize Earth’s climate and avoid the catastrophic consequences predicted in the IPCC report.
