Why similar changes in cloud cover can have different climate effects

AI Summary

Marine low clouds over the eastern subtropical oceans reflect sunlight and have a substantial cooling influence on Earth. Researchers highlight uncertainty about how these clouds will respond to warming and how changes in cloud cover could affect future climate projections.

Marine low clouds over the world's eastern subtropical oceans strongly influence Earth's temperature by reflecting sunlight back to space. How these clouds change as the planet warms is one of the biggest uncertainties in predicting the severity of future warming.
