Cornell Study: It's Not 97% Of Climate Scientists Supporting Warming Consensus - It's 99.9%
The scientific consensus that humans are altering the climate has passed 99.9%, according to research that strengthens the case for global action at the Cop26 summit in Glasgow.
The degree of scientific certainty about the impact of greenhouse gases is now similar to the level of agreement on evolution and plate tectonics, the authors say, based on a survey of nearly 90,000 climate-related studies. This means there is practically no doubt among experts that burning fossil fuels, such as oil, gas, coal, peat and trees, is heating the planet and causing more extreme weather.
A previous survey in 2013 showed 97% of studies published between 1991 and 2012 supported the idea that human activities are altering Earths climate. This has been updated and expanded by the study by Cornell University that shows the tiny minority of sceptical voices has diminished to almost nothing as evidence mounts of the link between fossil-fuel burning and climate disruption.
The latest survey of peer-reviewed literature published from 2012 to November 2020 was conducted in two stages. First, the researchers examined a random sample of 3,000 studies, in which they found only found four papers that were sceptical that the climate crisis was caused by humans. Second, they searched the full database of 88,125 studies for keywords linked to climate scepticism such as natural cycles and cosmic rays, which yielded 28 papers, all published in minor journals.
