Hard Rain

I met yesterday with two wise heads working on responses to climate change. At the end, I asked both what for them was iconic of the situation.

One mentioned Bob Dylan's Hard Rain.

The other told me something I cannot reveal, but also suggested "the real hockey stick" - that is, the sudden plunge in ocean pH occasioned by rapid CO2 flux. This is on the bottom of page 16 of Reviewing the impact of increased atmospheric C02 on oceanic pH and the marine ecosystem by Turley at al (here).
