Climate Change: What Do Scientists Say?

On many issues, scientists who for whatever reasons have climbed aboard the climate change bandwagon actually agree with the skeptical scientists who are willing to forego lavish grants and even risk their jobs rather than go along. In a vintage video from 2 years ago, MIT emeritus professor of atmospheric sciences Richard Lindzen lists a few points of agreement:

1. The climate is always changing.
2. CO2 is a greenhouse gas without which life on earth is not possible; adding enough of it to the atmosphere should lead to some warming.
3. Atmospheric levels of CO2 have been increasing since the 19th century.
4. Over the past 2 centuries, global temperatures have increased slightly and erratically by about 1.8°F; only since the 1960s have human greenhouse gas emissions been sufficient to play a role.
5. No confident prediction about future global mean temperature or its impact can be made.

Neither group says that burning fossil fuels will create a catastrophe. That belief comes from nonscientist know-nothings who exploit the issue for power and money, or in the case of environmental extremists, out of a deranged desire to offer up our standard of living as a sacrifice to The Planet.
