Climate change, the proof that what is called peer review is really pre-publication veto of non-compliant research:
This paper took some proxies that showed rapidly increasing warming a thousand years ago – during the Medieval Warm Period – and redacted them so that they show rapid warming now. They arbitrarily added 1000 years to each data point, showing ZOMG industrial Thermageddon caused by burning carbon in today’s factories when in reality the carbon would have been burned by monks in the day of William the Conqueror — via Borepatch: The “Hockey Stick” climate graph has been proved!.
Real peer review happens when papers are published first and everyone in the field can review them, with the cost of a wrong review being borne by the reviewer not the author. This is what used to happen in the early days of science.
As for “climate change,” it’s basically a way of giving power hungry regulators, governments, and busybodies an excuse to meddle into all production processes and uses of energy; in other words, to control the supply side of the economy (and some of the demand).
Interestingly, the other great government program of our time, “free health care,” is the way these same power-hungry entities regulate what individuals can do, that is the demand side of the economy. After all, if the collective is paying for your health care, your personal decisions are everyone’s business.
What a happy coincidence that control is being asserted over both sides of the economy at the same time. But trust these people, they would never abuse their power.
