Actually reading the article to the very end was lucky! The solution to the AGW problem is right there:
"Reflective buildings: Between 10 and 50 per cent of solar radiation can be reflected back out of the atmosphere by painting buildings and road surfaces in light colours."
50% of solar radiation can be reflected right back out of the atmosphere! A little drawback is that with 2/3rds of the earth covered with water we're going to have to paint the oceans white too so that'll take a while but it could take care of the unemployment problem ...
Although I am not a scientist I did take a very tough physics class in high school and I'm betting that whatever radiation heats the atmosphere as it comes in from the sun is going to heat it up on its way out and a fair amount will end up being bounced back down - not just reflected into outer space! These warm-mongering people are losing it .., let's keep up the pressure! ;-)
