The amount of solar energy that Earth receives has followed the Sun''s natural 11-year cycle of small ups and downs with no net increase since the 1950s. Over the same period, global temperature has risen markedly. It is therefore extremely unlikely that the Sun has caused the observed global temperature warming trend over the past half-century.

The Performance of Downward Shortwave Radiation Products

The downward shortwave radiation (DSR) is an important part of the Earth''s energy balance, driving Earth''s system''s energy, water, and carbon cycles. Due to the harsh Antarctic environment, the accuracy of DSR derived from satellite and reanalysis has not been systematically evaluated over the transect of Zhongshan station to Dome A, East Antarctica.

Antarctica as a Global Common Flashcards (AQA A Level

The albedo effect refers to the reflection of solar radiation by light-colored surfaces. As glaciers and ice sheets melt in Antarctica, the dark-colored ocean or land surface absorbs more of the sun''s energy, causing more warming and contributing to a positive feedback loop. It helps protect Antarctica by coordinating global policies
