On its Climate Science Information Centre, extended in February to South Africa, Facebook states that “at least 97% of published scientists agree that global warming is real and caused by humans”. Referring to the “claim” that global warming over the past century could be caused by the sun, Facebook says scientists have concluded that it could only have been caused by “the billions of tons of carbon pollution created by human activities” (emphasis added). It is, moreover, a “myth that scientists disagree on climate change”. Facebook further states that climate change is making “heatwaves, droughts, and wildfires more frequent and intense”, while damaging plant life and causing polar bear populations to decline. In 2014 John Kerry, then Barack Obama’s secretary of state and now Joe Biden’s special envoy on climate change, said that “97% of the world’s scientists” tell us it is “urgent” to deal with the “crippling consequences” of climate change. Mr Obama himself stated that “97% of scientists agree [that] climate change is real, man-made, and dangerous”.
