Nearly six in ten climate scientists don’t adhere to the so-called “consensus” on man-made climate change, a new study by the Dutch government has found. The results contradict the oft-cited claim that there is a 97 percent consensus amongst climate scientists that humans are responsible for global warming.
The study, by the PBL Netherlands Environment Assessment Agency, a government body, invited 6550 scientists working in climate related fields, including climate physics, climate impact, and mitigation, to take part in a survey on their views of climate science.
Of the 1868 who responded, just 43 percent agreed with the IPCC that “It is extremely likely {95%+ certainty} that more than half of [global warming] from 1951 to 2010 was caused by [human activity]”. Even with the “don’t knows” removed that figure increases only to 47 percent, still leaving a majority of climate scientists who do not subscribe to the IPCC’s statement.
The findings directly contradict the claim that 97 percent of climate scientists endorse the view that humans are responsible for global warming, as first made by Cook et al in a paper published in Environment Research Letters.
Cook’s paper has since been extremely widely debunked, yet so ingrained has the 97 percent consensus claim become that The Guardian has an entire section named after it, and President Obama has cited it on Twitter.
Commenting on the new study, Australian climate blogger Joanne Nova said: “Finally there is a decent survey on the topic, and it shows that less than half of what we would call “climate scientists” who research the topic and for the most part, publish in the peer reviewed literature, would agree with the IPCC’s main conclusions. Only 43% of climate scientists agree with the IPCC “97%” certainty.”…
