Greenhouse Gases Link to Materials?

With reference to the production of greenhouse gases and their effect on global warming, can anyone tell me if any in-depth research has been done to see if greenhouse gases are being produced when bricks, concrete, mortar, tarmac and other materials used in construction are heated by the rays of the sun or come into contact with carbonic acid (rainwater) or acid rain?

His letters inform us of the great suffering and abuses that these many asylum seekers have been subjected to.

No doubt there are a number of genuine asylum seekers but the seemingly incessant rhetoric by Peter Sagar is doing nothing to further their cause.

I, like many others, are not against the genuine asylum seeker, what we are fed up with is the continual arrival of many fit, and obviously well-nourished asylum seekers for whom the "only abuse" they have suffered is the rejection by this country. …
