Global warming...? Nothing supports global warming. All the scientific data suggests that global warming is a hoax introduced into the US by Al Gore. I do believe that the world warms and cools periodically. Human activity is very minimal compared to natural occurences that cause carbon dioxide. In fact, instead of global warming, the world seems to be entering a global cooling stage. I wouldn%26#039;t be surprised in the years to come that the word %26#039;global warming%26#039; is changed to %26#039;climate change%26#039; to support their claims.

Please support your criticisms with knowlegable facts instead of just blurting things out without support.

In 1970%26#039;s many scientists feared that a new Ice Age is coming. Because for a few years the weather was colder than usual.

In 1990%26#039;s the weather became a bit warmer than usual. And of course some scientists came up with a new theory to explain what%26#039;s going on.

I%26#039;m not an expert in Earth%26#039;s weather and climate. But I have a hard time believing these experts who often can%26#039;t predict well the weather one week into the future. They simply don%26#039;t know enough to predict accurately changes in climate many years into the future.

you say that human activity is too minimal to affect the level of carbon dioxide, but the level right now is at 375 ppm, the highest its ever been in 420000 years. we are recording high levels of carbonic acid which is produced from carbon dioxide, right in the ocean, reducing the PH level and posing a real threat to the acidity-sensitive fish species. the number of natural disasters have also risen:

i hope these site will help you to understand the facts that climate change is real and right on our doorstep. if you still don%26#039;t believe right now, you definitely will in 50 years time.

  Global warming is a fact and I don%26#039;t know if it%26#039;s happening now.
