Climate scientist Richard Lindzen of MIT spoke before a public meeting of the House of Commons in Great Britain yesterday. You can read his entire speech here [pdf]. Please do. He know his stuff. More important, he begins his presentation by immediately accepting these points:
- Carbon dioxide is increasing in the atmosphere.
- There is a greenhouse effect.
- There has been a doubling of CO2 in the past 150 years.
- There has probably been a warming of about 0.8 degrees Celsius in the past 150 years.
- Increasing CO2 alone should cause some warming.
He then notes that while none of these points are controversial among serious climate scientists, none of these facts are a cause for alarm.
The evidence is that the increase in CO2 will lead to very little warming, and that the connection of this minimal warming (or even significant warming) to the purported catastrophes is also minimal. The arguments on which the catastrophic claims are made are extremely weak – and commonly acknowledged as such. They are sometimes overtly dishonest. [emphasis mine]
