QUOTE: "a widespread brightening has been observed since the late 1980s.
This reversal is reconcilable with changes in cloudiness and atmospheric
transmission and may substantially affect surface climate, the
hydrological cycle, glaciers, and ecosystems."

Variations in solar radiation incident at Earth's surface profoundly
affect the human and terrestrial environment. A decline in solar
radiation at land surfaces has become apparent in many observational
records up to 1990, a phenomenon known as global dimming. Newly
available surface observations from 1990 to the present, primarily from
the Northern Hemisphere, show that the dimming did not persist into the
1990s. Instead, a widespread brightening has been observed since the
late 1980s. This reversal is reconcilable with changes in cloudiness and
atmospheric transmission and may substantially affect surface climate,
the hydrological cycle, glaciers, and ecosystems.
