Bacteria-ulcers weren't proven by people who really really really wanted them to be true, they were proven by a doctor, using (fairly unconventional) scientific methods. If you've got compelling historical sources for holocaust denial or compelling scientific evidence against climate change, let's see it.

or compelling scientific evidence against climate change Oh please. No one would even try in this political climate. As you said "don't believe in climate change? you are a nazi".

The feedback loop peaks out at a global temperature increase of 5-8 degrees celsius, if the models and past events are to be believed: https://en.wikipedia.org/wiki/Paleocene–Eocene_Thermal_Maxim...

Remember the sun wasn't so bright then either.

Geo-engineering projects could not come too soon. Because of how grand they are in scale, they don't seem to get much attention from the mainstream scientific community, but it seems feasible technologically (albeit expensive) to put forth major projects to reflect sunlight over deserts and capture significant amounts of carbon from power plants and oceans, amongst numerous other creative approaches. https://en.wikip…

Isn't a 5 - 8 degree rise catastrophic though? Genuine question.

Depends on what you consider catastrophic. 5-8C means you lose both the Greenland and Antarctic ice caps, so you get 60m (200 ft) sea-level rise, so you totally lose all the coastal cities, and the current round of civilization is almost certainly done for. But homo sapiens will probably survive, and so civilization will probably eventually be rebuilt. It won't be the end of life on earth under any circumstances. Act…

There is a lot of ignorance regarding what 5-8 degree warming means. The worst case scenario (and that is the only one we should be concerned with!) is a global mass extinction event. We've already had 5 of them - one of which was due to runaway greenhouse warming - https://cosmosmagazine.com/palaeontology/big-five-extinction... We cannot be sure we'll stop at 5 degrees or 8 degrees. After that we will have a mass ex…

How would every last human die? I mean, sure, millions or even billions . . . but not one human surviving with all the resources and resourcefulness we have at our disposal?
