Solar radiative energy declined in large parts of the world from the 1950s to the 1980s - known as "global dimming" - before a partial recovery since.

Amount of sunlight reaching Earth's surface varies over decades, researchers report

The sun may rise every morning, but the amount of sunlight reaching Earth's surface can substantially vary over decades, according to a perspective article led by an international research team.

The sun can rise every morning, but the amount of sun reaching the Earth's surface can vary considerably over the decades, according to an article of perspective led by an international research team. The article, published in Progress of Atmospheric Science, suggests that the stages of "gradation" and "clarification" correspond [...]
