Global Dimming - Action Needed

Global Dimming has been hiding the true power of Global Warming.

What is Global Dimming?

Fossil fuels produce both greenhouse gases and other pollutants, such as sulphur dioxide, soot, and ash. These other pollutants change the properties of clouds.

Clouds are normally formed when water droplets are seeded by air-borne particles, such as pollen.

Polluted air results in clouds with larger number of droplets than unpolluted clouds. This makes those clouds more reflective and less likely to precipitate as rain. As a result, more of the sun’s heat and energy is reflected back into space.
This reduction of heat reaching the earth has reached levels of 20% and is known as Global Dimming.

This was part of a talk I gave last month in Fairfield, Iowa at Maharishi University of Management.

You can download a copy of my Global Dimming talk here.

There is a video about Global Dimming done by BBC that I highly recommend watching.
