HiLAT-RASM: High Latitude Application and Testing of Earth System Models - Regional Arctic System Model

The Arctic region is warming faster than anywhere else on Earth. This project uses high-performance, multi-scale computer models to analyze the processes responsible for this accelerated warming, and its impacts on the entire planet

Keywords	Arctic amplification, arctic amplification The amplified surface warming in the Arctic relative to the global mean. Source: Pacific Northwest National Laboratory Source climate feedbacks, climate feedback Processes that can either amplify or reduce the effects of climate drivers (e.g., solar radiation; greenhouse gas emissions; and aerosols, dust, smoke, and soot). A feedback that increases an initial warming is called a "positive feedback." A feedback that reduces an initial warming and then returns the system to it's original state is a "negative feedback."
