I don't claim to have any scientific expertise, particularly in the specialised field of climate science, so I'll leave it to those more qualified than me, whose opinions I respect, to fill in the details.

before giving a very impassioned argument for doing whatever it takes to stop climate change. She points out, even if we're wrong, that

nothing will be lost other than a few years of economic growth.

In other words, if we waited for people with expertise before we did anything, imagine the world we might leave for our children, and our children's children.
