Good to see you post again, Bob. You always get my spirits up.
Glad to be of service.
I'm very optimistic about our ability to solve our CO2 problems.
I'm not as optimistic about our willingness to solve them as quickly as we should. We should already be most of the way there. We aren't.
In terms of avoiding a lot of climate change hurt I'm, at best, hopeful. I hope we're seeing the last significant rearguard action by the fossil fuel industry. I see signs of big oil preparing to leave the field of battle and transform into renewable energy companies (mostly offshore wind). I think coal is in the process of losing everywhere but still has enough power to slow renewables for a few more years. I think natural gas has a significant role to play over the next decade or so but storage looks like it will wipe out gas well before 2030.
Then I'm prayerful. As much as a non-believer can be. We really need some atmospheric greenhouse gas removal technologies. I don't see anything meaningful yet.
But overall I'm optimistic. Given how recently we began to address climate change I'm impressed at how rapidly our renewable energy and storage technologies have evolved. And at how very rapidly costs have fallen. I think it possible that we could be largely fossil fuel free in 20 to 25 years.
Do that. Figure out how to pull back some of our greenhouse gas blanket. That might take enough energy out of the climate system to lower temperatures, reduce storm intensity, and decrease rain bombs.
Higher sea levels. Can't see any option but adapting. At least when we rebuild our coastal buildings a bit inland we can build highly efficient buildings.
