Communicating the Climate Emergency
The Climate Emergency Institute provides science-based analysis of global warming, greenhouse gas emissions, and the accelerating risks to human health, ecosystems, and civilization — especially agriculture and food production — along with science-based emergency solutions. The current focus is communicating the all-important fact that global emissions had to be in decline with “immediate action” by 2025 for the 1.5°C and 2°C limits (IPCC 2022).
Founded by Dr. Peter Carter in response to James Hansen’s 2008 declaration of a planetary emergency, the Climate Emergency Institute provides independent, science-based analysis of global warming, greenhouse gas emissions, and the accelerating risks to human health, ecosystems, and civilisation. The Institute receives 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.
