The science of the climate emergency — presented plainly.
The Climate Emergency Institute provides science-based analysis of global warming, greenhouse gas emissions, and the accelerating risks to human health, ecosystems, and civilisation. Founded by Dr. Peter Carter, IPCC expert reviewer, in response to James Hansen’s 2008 declaration of planetary emergency. No government or industry funding.

Independent. Science-based. Since 2009.
The Climate Emergency Institute was founded by Dr. Peter Carter in response to James Hansen’s 2008 declaration that we face a planetary climate emergency. It operates with no government or industry funding.
Dr. Carter is a retired physician, IPCC expert reviewer, and founding director of the Canadian Association of Physicians for the Environment. His approach applies a health and human rights framework to greenhouse gas pollution.
