The Earth, the earth The earth is on fire...?

Again, the issue is not whether or not there is Global warming. The issue is whether WE are causing it.

Here is another article that says no. Here are some quotes by an article from Pierre DuPont:

Plus Ça (Climate) Change

...a look at the data shows that within the century temperatures varied withtime: from 1900 to 1910 the world cooled; from 1910 to 1940 it warmed; from 1940 to the late 1970s it cooled again, and since then it has been warming. Today ourclimate is 1/20th of a degree Fahrenheit warmer than it was in 2001.
...Solar radiation is reducing Mars's southern icecap, which has been shrinking for three summers despite the absence of SUVS and coal-fired electrical plants...
Half of the past century's warming occurred before 1940, when the human population and its industrial base were far smaller than now.
While Al Gore's "An Inconvenient Truth" warns of up to 20 feet of sea-level increase, the IPCC has halved its estimate of the rise in sea level by the end of this century, to 17 inches from 36. It has reduced its estimate of the impact of global greenhouse-gas emissions on global climate by more than one-third, because, it says, pollutant particles reflect sunlight back into space and this has a cooling effect.

Those quotes are all illuminating, but the greatest threat of an inaccurate diagnosis of human-caused global warming is similar to the inaccurate assertions made against the use of DDT to curb the spread of malaria. DuPont says:

Sometimes the consequences of bad science can be serious. In a 2000 issue of Nature Medicine magazine, four international scientists observed that "in less than two decades, spraying of houses with DDT reduced Sri Lanka's malaria burden from 2.8 million cases and 7,000 deaths [in 1948] to 17 cases and no deaths" in 1963. Then came Rachel Carson's book "Silent Spring," invigorating environmentalism and leading to outright bans of DDT in some countries. When Sri Lanka ended the use of DDT in 1968, instead of 17 malaria cases it had 480,000.

That is why we better be pretty sure we are the problem before we decide to "fix the problem."
