See the submenu for items related to global warming that are archived here, so I don’t have to keep repeating the same arguments to sceptics who keep repeating the same old arguments.
Recently (Jan 13, 2015) I have decided it’s past time to stop humouring climate skepticism and denial. Why? Because tolerating it only helps to perpetuate the myth that climate scientists are divided and there’s a lot of doubt about the cause of global warming. It feeds the trolls.
Climate science, like all science, has a well-developed bullshit filter. It’s not perfect, but it gets rid of much of the nonsense. Not only does climate skepticism not have such a filter, it has a plentiful supply of non-scientist bullshitters, and they are fed by a professional disinformation industry that generates copious amounts of bullshit. One of the biggest pieces of bullshit is that there is a scientific conspiracy to exaggerate the threat. That conspiracy theory is really the last remaining resort of denialists.
The balance of scientific opinion was recently estimated to be about 99.83% for, 0.17% against, the proposition that we are causing global warming. James Lawrence Powell counted papers published between 1991 and 2012. Here’s his result:
So, no more bullshit here.
