global warming

I know the climate has been warmer and dryer. I don't think it is the greenhouse effect. Human's activity do accelerate the speed of warm but I believe it is due to the circle of climate. It will contiune to warm up for thousands of years then contiune to colder and coler for another thousands of years.

im aware of it coz the climate at my place are no longer the same as before its getting hotter! and after watching Al Gore documentary its certainly open my eyes

Very much aware because every time I go out in the sun, the sun rays will bite my skin. The sun rays can no longer be filtered because the ozone layer is already destroyed. If we don't act now the problem may escalate later and it will be horrific to think about the final outcome of our planet. Let's hope for the best.
