And if you don't believe Arnie, check out these factoids:
In June 2005 the National Academies of Science for all G8 Nations, along with China, India and Brazil, signed a joint-statement stating that there is strong evidence that global warming is happening and that most of it can be attributed to human activities. This was signed by the top government scientific advisors in Canada, the United States, the United Kingdom, Japan, Italy, France, Germany, and Russia.
In 2004, 48 Nobel Prize Winners in science signed a letter to US President George Bush, stating that: “By ignoring scientific consensus on critical issues, such as global climate change, the US government is threatening the earth’s future.”
In 2001, the National Science Academies of 16 countries, including Australia, Canada, the UK, China, Indonesia, India, Italy, Malaysia, France and Brazil, signed a joint document stating:
“There will always be some uncertainty surrounding the prediction of changes in such a complex system as the world’s climate. Nevertheless, we support the IPCC’s conclusion that it is at least 90% certain that temperatures will continue to rise… and this increase will be accompanied by rising sea levels, more intense precipitation events in some countries, increased risk of drought in others, and adverse effects on agriculture, health and water resources.”
Statements like these from the leading scientific bodies in the world and Schwarzenegger's quote underscore how ridiculous the claims of “skeptic” scientists, like Pat Michaels, Tim Ball and Fred Singer, and polticians like Senator Jim Inhofe actually are.
