Short summary
We explore how Pacific low-level clouds influence projections of regional climate change by adjusting a climate model to enhance low-cloud response to surface temperatures. We find significant changes in projected warming patterns and circulation changes under increased CO2 conditions. Our findings are supported by similar relationships across state-of-the-art climate models. These results highlight the importance of accurately representing clouds for predicting regional climate change impacts.
