Led by a Nobel Prize laureate, more than 1,100 scientists and scholars have signed a document declaring climate science is based more on personal beliefs and political agendas than sound, rigorous science.

The World Climate Declaration states climate science "should be less political, while climate policies should be more scientific."

"Scientists should openly address uncertainties and exaggerations in their predictions of global warming, while politicians should dispassionately count the real costs as well as the imagined benefits of their policy measures," the declaration reads.

The declaration was organized by Climate Intelligence, an independent policy foundation founded in 2019 by Dutch emeritus professor of geophysics Guus Berkhout and Dutch science journalist Marcel Crok.
