Researchers have identified a mechanism that causes low clouds and their influence on Earth’s energy balance to respond differently to global warming depending on their spatial pattern and location. Despite having a positive cloud feedback in response to long-term projected global warming, the model exhibits a strong negative cloud feedback over the last 30 years. "With a combination of climate model simulations and satellite observations, we found that the trend of low-level cloud cover over the last three decades differs substantially from that under long-term global warming" said Chen Zhou, lead author of the paper.In response to increased carbon dioxide, climate models predict a nearly uniform warming of the planet that favors reductions in highly reflective low clouds and a positive feedback. The team emphasized that clouds are particularly sensitive to subtle differences in surface warming patterns, and researchers must carefully account for such pattern effects when making inferences about cloud feedback and climate sensitivity from observations over short time periods.
Recently, the public has been hearing humans are the soul reason for global warming. However, now we know it is from several reasons including clouds. In addition, there is still more data to me counted and tested for global warming causes. https://www.sciencedaily.com/releases/2016/11/161101093858.htm
