Did you hear about "Climate Change"?

I accidentally found one site on the Web. That's "Blog Action Day".
This site says

"Blog Action Day is an annual event held every October 15 that unites the world’s bloggers in posting about the same issue on the same day with the aim of sparking discussion around an issue of global importance. Blog Action Day 2009 will be one of the largest-ever social change events on the web."

I immediately joined this event because I sympathize the aim.
The issue of this year is "Climate Change". And in Japan, today is already October 15, so I want to post about "Climate Change" today.

I think it had snowed heavily when I was kid. I used to make snowman in my childhood. But recently, it's a few times that the snow pile up. And I heard the snowfall of Mt. Kilimanjaro in Africa becomes less and less every year.
Why? "The Global Warning" is one of the cause? I exactly don't know which is right or wrong. But we should do everything what we can for stopping the global warning. It's good to do a slight thing.
For example, turning off the light of the room nobody stay, don't crank up the air conditioner so much, trying to use the public transport, etc...

Now, if we act nothing, the world may be irrecoverable by ourselves...
