Cloud feedback refers to the response of clouds to surface temperature change. A positive cloud feedback would amplify greenhouse gas-induced warming and have a stronger cooling effect from aerosol‐cloud interactions. Uncertainties in predicting cloud feedbacks are the largest cause of spread in model predictions of future global warming.
A recent study published in Nature Communications Earth & Environment suggests that summertime low clouds play an important role in driving sea ice melt.
Weather and climate models are an essential part of predicting extreme weather events and projecting future changes in climate. Since these models can enable better disaster preparedness and reduce risks related to extreme weather, it is important to ensure that their simulations include limited bias or error.
Accurately simulating summertime large-scale circulation, as well as the cloud response to circulation, is a critical step toward increasing the reliability of seasonal sea ice forecasts and the rate of future sea ice loss.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
