AGW


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.
