Where Scientists Stand on Climate

Where Scientists Stand on Climate

Laser Talk

Question:  Don’t a lot of scientists still disagree that climate change is caused by humans?

Answer: No. There are only a very few, and even fewer who have scientific backgrounds relevant to climate science. Many individuals who pose as “experts” in media sources are not scientists at all, or else have no real background in climate science.

You want proof? Seven different research groups looked into this over the last 12 years, examining thousands of papers and/or asking hundreds of scientists directly for their position on climate change. They found that between 91 and 100 percent of published climate scientists agreed, based on the evidence, that human-caused global warming is occurring. The average was about 97 percent. [1] Not only that, but the National Academy of Sciences and their counterparts from 79 other nations also agree, as do all major American member organizations of physicists, chemists, meteorologists, and astronomers. Not a single one claims that human-influenced global warming is in doubt. Not one. [2]

This is important, because when people learn how strong the scientific agreement really is, they are more inclined to transcend political affiliations and support public policy solutions to climate change. [3]

In a Nutshell: 97 percent of climate scientists are convinced, based on the evidence, that human-caused global warming is happening. This has been confirmed by multiple studies.
