The favorite cudgel of leftist climate change fear mongers is the appeal to authority, as in that there is “a scientific consensus” that the earth is warming and that changes over the last century are due to human activity. The problem with appeals to authority on extremely broad scientific topics is that they are not subject to easy proof by experimentation, and are quite often wrong.
Here’s a list of ten popular theories ultimately proven false, and it omits some major howlers, like therapeutically bleeding people or the geocentric theory of the solar system. Now we can add to that list the “scientific consensus” that diets rich in processed foods and fats lead to heart disease. This idea, which has dominated medical thinking for at least the last half-century, and led to all manner of government policy making, regulation and just plain tsuris over finishing the brisket, is now in doubt........
I am not a climate scientist, but I am a historian, and one thing that is certain is that the earth’s climate has obviously undergone dramatic change in both historic and prehistoric time frames. In historic time (that is in the last 5000 years or so) there has been massive desiccation in northern Africa and the Middle East (probably due to long term warming)interspersed with mini-ice ages (countervailing periods of cooling especially in northern latitudes.) On balance, at least for people in the northern hemisphere (which is where most of the human population resides) warming has been a good thing, while cooling (with associated famines) a bad thing........Read more:
