How does Concrete effect global warming?
I was reading through the answers of another very timely question about Nuclear power and thought about the carbon footprint of concrete. Also is nuclear just "stop gap" when we talk non renewable? Sorry for all the side questions,but when it comes to regulations isn't there a difference between government and politics? Alexis are you Riche's daughter?

Cement production releases 5% of anthropogenic CO2 emissions. Cement is made from limestone and in doing so releases CO2, but also requires energy which if generated by fossil fuels doubles the CO2 output. The raw materials include limestone, shale and clay which all contain carbon. These must be heated to 1450 degrees... More

First, ignore the twit who says "it is just the sun". There are satellites up which have been measuring the amount of sunlight hitting the earth. There has been no increase- in fact there has been a slight *decrease* in sunlight. So how a decrease in solar energy causes the observed average temperature of the globe... More
