I wanted to hit the sack but a video clip in English of some excerpts from an interview of John Holdren by German intellectual paper DIE ZEIT. Click here::
At about the 3:40 mark, Holdren is asked what will be the sciences of the future and the challenges. This takes him to climate change:
We are fortunately getting better, and we need to get better at understanding some very big systems, science systems issues including for example the science of ecosystems, the formation and fertilisation of soil, the pollination of crops, the regulation of climate. All of these things I think sometimes get lost in the discussion of the importance of infotech and nanotech and biotech. We need to understand how the parts fit togther, how they work because we are not yet remotely ready technologically to make planet earth into a speceship where all systems are designed by engineers. We still need nature, We need to understand how it works.”
I thought the science was settled. But Holden now admits that we still need to understand how it all fits together – how it works. So how CO2 controls linearly controls the temperature, we we keep seeing in their charts, is a bit puzzling to me.
