Are you frightened by climate change? …In the words of science writer and author David Wallace-Wells, “No matter how well informed you are, you are surely not alarmed enough.” …If the fracturing of our once stable climate doesn’t terrify you, then you don’t fully understand it. The reality is that, as far as we know, and in the natural course of events, our world has never — in its entire history — heated up as rapidly as it is doing now. Nor have greenhouse gas levels in the atmosphere ever seen such a precipitous hike. …What’s happening to our world scares the hell out of me, but if I shout the brutal, unvarnished truth from the rooftops, will this really galvanize you and others into fighting for the planet and your children’s futures? Or will it leave you frozen like a rabbit in headlights, convinced that all is lost? It is an absolutely critical question.
