Today, the New York Times has a story about a report on climate change just released by the American Association for the Advancement of Science (AAAS), the world’s largest non-governmental general science membership organization.

AAAS convened a task force of climate science experts, economists, community leaders and policy makers for its “What We Know” Initiative, to address the continuing lack of public awareness of the full spectrum of climate risks. Scientists from Harvard, MIT, Stanford, Woods Hole and other research institutions are guiding the effort to educate people about the scientific evidence on climate change, raise the alarm about serious risks and consequences to the planet, and debunk myths and misinformation.

The report contains no new science. Instead, it is clearer and “more accessible than perhaps anything the scientific community has put out to date,” the Times writes. The initiative is intended to cut through public confusion, and identify:

The Reality–Surveys show that the public is somewhat concerned about climate change, but believes there is still significant scientific disagreement about the causes. This is FALSE. According to AAAS, “Based on well-established evidence, about 97% of climate scientists have concluded that human-caused climate change is happening.”

The Risk–AAAS writes: “Earth’s climate is on a path to warm beyond the range of what has been experienced over the past millions of years. The range of uncertainty for the warming along the current emissions path is wide enough to encompass massively disruptive consequences to societies and ecosystems: as global temperatures rise, there is a real risk, however small, that one or more critical parts of the Earth’s climate system will experience abrupt, unpredictable and potentially irreversible changes.”

Worst case forecasts include severe food shortages, rising seas that would inundate coastlines, extreme heat waves, droughts and floods, and massive extinction of plants and animals.  (more…)
