I do have to agree on the blacktop and concrete being the cause of temps to rise in a local area, but not over a large area, just to much earth and
water to really make that much of a global increase.
The earth is always changing, Methane gas released from the ocean floor and from volcanic activity, the ash and gases released is the major cause of
the slight increase in global warming.
There is volcanic action going on all the time all over the world, dumping tons of NATURAL pollutants in to the air, yes mankind has put a dent in the
atmospheric conditions, but the earth is constantly cleansing and renewing itself, just look at the ozone hole at the south pole, you havent heard a
word on it lately because its size has reduced to just about nothing.
Yes mankind needs to be more polution aware, which has been done over the last 20 years in the US and I think we are going in the right direction with
EPA giudelines that are in place in the US, just now the rest of the world needs to follow along!
And in addition the sun is on a 21 year cycle of sun spot activity which can make the earth average temp warmer, so this is something we are going to
have to live with.
