Critically examine any future environmental scares, in light of the dishonest attempt to stampede the public that has been perpetrated in the case of this Global Warming hoax. Support continued honest observational science on climate and other large-scale environmental issues. I have taken a keen interest in the Global Warming issue, ever since seeing the graph of world temperature for the past 100 years, and realizing at a glance that it was nothing to worry about. That was about 12 years ago.
Humans burn coal, oil, gas, forests, and so on.
This releases carbon dioxide into the air. Various other farming and industrial processes release other gases that, like carbon dioxide, trap heat better than the nitrogen and oxygen that make up most of our air. That initial warming evaporates more water, which adds a lot to the greenhouse effect. Or at least, so the theory goes. And we are constantly told that scientists say this is true, or that most scientists do.
