The flood of coverage of the Nature papers I mentioned yesterday (It’s Crunch Time) continues.
Of most interest, by far, is a longish historical look at how the climate science arrived at its current state of understanding, Climate crunch: A burden beyond bearing. The article details how we went from thinking 550ppm was the “magic number” for CO2 concentration in the atmosphere to 450ppm to (possibly) 350ppm. It also describes the areas some researchers are working on now, which I suspect will lead to some unsettling conclusions. I won’t even try to provide pull quotes for this article, and will simply ask (read: beg) you to find a few minutes to go read it all.
With just a little luck I should have copies of the two main articles soon. When that happens, I will post my own impressions of them.
