evidence: Myth #2: Climate change is a natural process. It has nothing to do with people. [...] A 2021 study revealed that 99 per cent of peer-reviewed scientific literature found that climate change was human-induced. That was in line with a widely read study from 2013, which found 97 per cent of peer-reviewed papers that examined the causes of climate change said it was human-caused. "The idea that there is no consensus is used by climate deniers to muddy the waters and sow the seeds of doubt," says Tsering. "But the scientific community agrees: the global warming we are facing is not natural. It is caused by humans."
