[Ed. – Lindzen’s point is so important. When the uncertainty factor is in tenths of a degree, you can’t claim anything with long-term meaning about a change of hundredths of a degree.]
The scientists appeared at a climate summit sponsored by the Texas Public Policy Foundation. The summit in Austin was titled: “At the Crossroads: Energy & Climate Policy Summit.”
Climate Scientist Dr. Richard Lindzen, an emeritus Alfred P. Sloan Professor of Meteorology at the Department of Earth, Atmospheric and Planetary Sciences at MIT, derided what he termed climate “catastrophism.”
“Demonization of CO2 is irrational at best and even modest warming is mostly beneficial,” Lindzen said.
Lindzen cautioned: “The most important thing to keep in mind is – when you ask ‘is it warming, is it cooling’, etc. — is that we are talking about something tiny (temperature changes) and that is the crucial point.” …
“We are speaking of small changes 0.25 Celsius would be about 51% of the recent warming and that strongly suggests a low and inconsequential climate sensitivity – meaning no problem at all,” Lindzen explained.
“I urge you when looking at a graph, check the scales! The uncertainty here is tenths of a degree,” he noted.
“When someone points to this and says this is the warmest temperature on record. What are they talking about? It’s just nonsense. This is a very tiny change period. And they are arguing over hundredths of a degree when it is uncertain in tenths of a degree,” Lindzen said.
