The Climate Intelligence Foundation (CLINTEL) was founded in 2019 by emeritus professor Guus Berkhout (TU Delft) and the Amsterdam based science writer Marcel Crok. CLINTEL operates as a watchdog of climate science and climate policy and intends to be a reasonable voice in the polarized climate debate.
Guus Berkhout also initiated the World-Climate-Declaration which operates under the Global Climate Intelligence Group, an international network of over 800 scientists and professionals.
