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

Lets just suppose for a minute that AGW really exists. In this case the answer to your question is that it doesn't have any affect other than increasing the temperature in and around where the concrete is poured due to it's effective way of absorbing the suns energy. Oddly enough these are the places that many of our... More

That was actually a matter considered by the engineers working on wind energy projects that I was involved with a while back. Although the efficiency of wind energy is considerably higher than many people not knowlegable about the industry allow, there is a question about when the net CO2 reduction benefit of the... More

If concrete causes global warming then what material could replace the concrete in any major building structures? Bamboo sticks? Both governments and politics are controlled by Banking Cartels a thousand times bigger and powerful then the mafia. Think about it..

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
