More On Global Warming.

This article says that 13% of Americans have NEVER heard of global warming. How is that possible? Are these people completely self-involved?

The news today is that the world's top climate scientists have said that mankind is to blame for global warming.
The scientists said it was "very likely" -- or more than 90 percent probable -- that human activities led by burning fossil fuels explained most of the warming in the past 50 years.
Even if human activities do NOT explain most of of the warming in the past 50 years, I'm sure it hasn't helped. Maybe this declaration will help shake things up in the U.S. and create some change. We can only hope.

There you have it.

I just read this article from Reuters about an ice core sample that was taken in the
Antarctic. Here's the gist of it:
It is from air bubbles that we know for sure that carbon dioxide has increased by about 35 percent in the last 200 years. Before the last 200 years, which man has been influencing, it was pretty steady. ...carbon dioxide today is not just out of the range of what happened in the last 650,000 years but already up 100 percent out of the range. The ice core record showed it used to take about 1,000 years for a CO2 increase of 30ppmv. It has risen by that much in the last 17 years alone.

If that's a natural occurrence, that's quite a coincidence. Even if it is natural, it still means that people need to decrease the amount of CO2 they put in the atmosphere. No matter where it comes from, too much CO2 is bad.
