Global Dimming
Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface that was observed for several decades after the start of systematic measurements in the 1950s. The effect varies by location, but worldwide it has been estimated to be of the order of a 4% reduction over the three decades from 1960–1990. However, after discounting an anomaly caused by the eruption of Mount Pinatubo in 1991, a very slight reversal in the overall trend has been observed.

Global dimming is thought to have been caused by an increase in particulates such as sulfate aerosols in the atmosphere due to human action.

It has interfered with the hydrological cycle by reducing evaporation and may have reduced rainfall in some areas. Global dimming also creates a cooling effect that may have partially counteracted the effect of greenhouse gases on global warming.

Humans Will be Extinct in 10 years: Dr. Guy Mcpherson
In this video I interview Guy McPherson a biologist and professor emeritus of the University of Arizona. He currently resides on a homestead in Belize. Dr. Mcpherson believes that the biggest threat facing mankind is global warming, that the threat is being downplayed and that its long past the point of being resolved as a phenomenon called 'runaway climate change' has already been put in motion.
