thank you steven chu,

for you are a very wise man. to paraphrase:

"The Nobel laureate in physics called for a "new revolution" in energy generation to cut greenhouse gas emissions.

Making roads and roofs a paler colour could have the equivalent effect of taking every car in the world off the road for 11 years, Chu said.

It was a geo-engineering scheme that was "completely benign" and would keep buildings cooler and reduce energy use from air conditioning, as well as reflecting sunlight back away from the Earth.

For people who found white hard on the eye, scientists had also developed 'cool colours' which looked to the human eye like normal ones, but reflect heat like pale colours even if they are darker shades.

And painting cars in cool or light colours could deliver considerable savings on energy use for air conditioning units, he said.

Speaking at the start of a symposium on climate change hosted by the Prince of Wales and attended by more than 20 Nobel laureates, Chu said fresh thinking was required to cut the amount of carbon created by power generation."

i completely agree that these steps, as well as many other simple steps, should be effective immediately. it is imperative that we exercise our ability to help the earth. after all, where else are we going to live if this place goes bad?
