Effects of clouds on climate change

Researchers developed a statistical learning analysis based on data from Earth observations and climate model simulations to estimate the uncertain effect of clouds on climate change and found that clouds have an amplifying effect on global warming; the results suggest that a doubling of pre-industrial atmospheric CO2 levels would almost certainly result in more than 2 °C of global warming, due to the amplifying effects of cloud feedback, resulting in substantial future warming, according to the authors.
