Global Warming

This comment was in an internet article concerning the best way to reverse global warming; "ADVANCED: Go with a white roof or install a green roof, which will prevent heat loss through the roof in winter and cool your home down in the summer."

All of the methods in that articles sound plausible to achieve energy efficiency, but there are other items that need to be questioned. The history of our warming trend is slow, but what was energy usage in the late 19th and early 20th centuries; Homes were inefficient, 'leaky air gap shacks', cooking was fire, early trains and steam ships as well as industrial power producers were inefficient, with a long list of waste heat. After the fire storms of WWII warming might have begun. As a child in the early 50's the A bomb and H bomb testing were said to be the causes of wild weather swings. Obviously they are almost non-existent today.

A question in this writers mind is the paving of the world. Walk bare footed on local streets black top in the summer time and calculate the total warm effect. The Interstate highways have covered some percentage of the United States. The remainder of the world is progressing while local housing projects are reducing the number of trees. Hard wood tree plantings are incidental to highway projects.   

Maybe the street should be painted white. Seriously, if we find a methods to begin cooling of our planet would we be facing an ice age? What we would face, and are slowly morphing into is a world government that will tell more of us what  we are allowed or not allowed to do?
