The IPCC (Intergovernmental Panel on Climate Change) actually has a name for Business as Usual. They have modeled it. They have a number for it. It's called the RCP-8.5.
I am preparing a three part article which provides scientific evidence that the RCP-8.5 scenario is too conservative. I cover what we can expect in the next 85 years or so.
Here's a graph to give you a sneak peak at the article contents:
Business as usual is a death sentence for over 75% (or more) of life on Earth.
Stay tuned for the article. you won't disappointed. The people that defend business as usual won't like it. Good.
