Summary:

- NASA's Prefire satellites have captured the first-ever direct observations of heat transport from the tropics to the poles, a phenomenon known as "polar heat."
- These observations provide new insights into the mechanisms behind the rapid warming of the Arctic and Antarctic regions, which are experiencing some of the fastest rates of climate change on Earth.
- The data from the Prefire satellites will help scientists better understand the complex interactions between the tropics and the poles, and improve the accuracy of climate models used to predict future global temperature changes.
