What do scientists say?

The scientific bodies of over 90 countries recognize that climate change is mostly human-caused and a problem that poses risks to people all over the world.(1) These scientific bodies, known as ‘national academies’, are among the most prestigious scientific associations in the world. The world’s leading national academies, from the U.S. to China, publicly acknowledge the concept of human-driven climate change.

National Academies Who Publicly Recognize Climate Change


Despite strong scientific support and over 20 years of international negotiations to reduce emissions, an international climate agreement remains elusive. Recognizing the large risks from further unmanaged greenhouse gases, the national academies have regularly petitioned world leaders to come to terms. Some petitions date back to nearly 15 years ago.

“Climate change is one of the defining issues of our time. It is now more certain than ever, based on many lines of evidence, that humans are changing Earth’s climate.”

“The need for urgent action to address climate change is now indisputable.”
– Joint Statement by the G8+5 countries (May 2009)

“The balance of the scientific evidence demands effective steps now to avert damaging changes to the earth’s climate.”
Joint statement by the Australian, Brazilian, and Chinese Academy of Sciences, and 13 more (May 2001)

“A consensus, based on current evidence, now exists within the global scientific community that human activities are the main source of climate change and that the burning of fossil fuels is largely responsible for driving this change.”
Joint Statement by Network of African Science Academies (June 2007)
