From The Guardian:
There are three options in tackling climate change. Only one will work
We’re now at a fork in the road: either we cut out fossil fuels completely, or we pass on a dying planet to our children
A "fork in the road" usually refers to a binary choice, i.e. go left or go right. To my mind, this jars uncomfortably with the notion of "three options".
And no amount of CO2 will ever lead to a "dying planet". It'd take something like a global nuclear war to get anywhere near that.
