The earth is getting warmer, this is established. The cause, and whether or not this will have any serious repercussions are unknown. Given the potential severity of the situation, I think we'd be better off playing it safe and trying to better understand the situation, and what should (or even can) be done.
But my question is why warming gets all the attention? There are many other very real issues in our environment that also need attention. Many of which require the same attention as global warming scientists say that needs.
Our Ozone is still a wreck. We have some serious smog problems in many areas. A good chunk of what should be drinking water is now polluted.
Remember the air conditions issue in China around the Olympics?
Forget about global warming completely and the simple fact remains, we are doing some serious damage to our environment, and it is hurting us. The weather is only one issue, the sun, the air and the water are also a part of the puzzle. Oddly enough, they all have the same preventative process, reduce emissions and other forms of pollution.
