Back in the 1970’s the Climate Scare was all about Global Cooling. Naturally it was all caused by wicked man’s industry and his pollution of the atmosphere. There was a consensus.
But the temperature trends changed, so the alarmists changed. Even the same people who figured prominently in the Global Cooling Scare later became leaders of the Global Warming Scare. We are again told there is a consensus.
Bad science is made by consensus. Good science is made by critical analysis of facts. Analysis of facts suggests that global cooling is probably more likely than global warming. Facts also suggest that humans have very little effect on climate trends.
