If you pay attention to the media reporting on “climate change” (note 1) you will often read/hear something like this:
Under a business as usual scenario..
And then some very worrying future outcomes. Less misleading, but still very misleading, you might read:
Under a high emissions scenario..
Every time I have checked the papers that are behind the press release faithfully reproduced by the stenographers in the media, they are referring to a model simulation using a scenario of CO2 emissions known as RCP8.5.
This scenario – explained below – is a fantastic scenario, and was not created because it was expected to happen.
So – calling it “business as usual”, charitably speaking, is from climate scientists who know nothing about history, demography, current & past trends. And uncharitably, is from climate scientists who are activists, pressing a cause, knowing that stenographers don’t do research or ask difficult questions.
