Former Governor of Florida and possible Republican presidential candidate, Jeb Bush, is disputing the scientific consensus on climate change. He says the science behind climate change is “convoluted.”
“I don’t think the science is clear of what percentage is man-made and what percentage is natural. It’s convoluted.”
He went on
“For the people to say the science is decided on this is really arrogant, to be honest with you.”
But Mr. Bush’s view is wrong. The science is clear; climate change is caused by human activities.
- Of the climate scientists who actively publish research, 97 percent agree that humans cause climate change.
- The U.N. Intergovernmental Panel on Climate Change — which draws on the knowledge of almost 800 climate experts across the globe — says it is at least 95 percent likely that human activities are the main cause of atmospheric and ocean warming since the 1950s.
In the scientific world, a 97 percent rate of agreement does amount to a consensus. No scientific issue is 100 percent certain. Indeed, there are similarly small percentages of researchers who think the HIV virus does not cause AIDS, and that smoking cigarettes does not cause cancer.
