I want to go back to some of the comments you're making around climate change. I thought that was interesting.
It's always a little bit dangerous to go into that topic. It sounded as though what you're really saying is you're talking about the evidence base and the opportunities that exist through our efforts in space to maybe identify holes in the evidence base, in a sense, and to actually impact our decisions based on actual evidence. Maybe you could comment on the evidence base as it relates to climate change.
