“In conclusion, the IPCC misled an entire generation of scientists and policy-makers, telling them the human impact on the Earth’s climate poses a genuine threat to human well-being and other life on the planet while deliberately and repeatedly hiding uncertainty, the absence of critical data, and evidence that questions or contradicts its apocalyptic prediction. Many thoughtful and well-intended people accept the IPCC’s claims unconditionally, taking at face value its claim to represent the “consensus of scientists.” They were betrayed. The result is a terrible crime against science, the adoption of unnecessary and very costly public policies, and grave damage to the reputation and credibility of science.”
