An MIT scientist has said that although the global temperature rise owing to a greenhouse effect is real, the increase is small and does not pose any existential threat.

The greenhouse effect is primarily caused by water vapor and clouds, said Richard Lindzen, professor emeritus of atmospheric sciences at Massachusetts Institute of Technology (MIT).

Carbon dioxide (CO2), methane, and nitrous oxide are minor constituents of the greenhouse effect, Mr. Lindzen told EpochTV’s “American Thought Leaders” in an interview.

“If all other things are kept constant, and you double CO2, you would get a little under one degree of warming,” Mr. Lindzen said. Some climate models estimate the highest warming at three degrees, but “even three degrees isn’t that much,” he added.

“We’re dealing with changes for a doubling of CO2 on the order of between breakfast and lunch,” he said.

According to NASA, the greenhouse effect is…
