Arctic as the ‘radiator fins’ of Earth in a warming climate
Abstract Earth radiates thermal radiation to balance the solar radiation it receives. Central to understanding climate change is how the radiation energy budget adjusts both globally and locally to external and internal forcing. In the past 18 years, satellite observations reveal a distinct positive...

Abstract Earth radiates thermal radiation to balance the solar radiation it receives. Central to understanding climate change is how the radiation energy budget adjusts both globally and locally to external and internal forcing.
