[some rough notes]
Climate change is real:
Our economic system is broken w.r.t. Climate Change:
Our political system is broken w.r.t Climate Change
We need to act but have failed to do so:
It is likely that global dimming has happened, that is the pollution wr have teased into the air has reflected more sunlight than is natural. When we clean up our pollution, as we must, then we get more sun and so more warming without releasing more CO2. Roughly our warming would and will be twice as much without the associated pollution https://www.scientificamerican.com/article/cleaning-up-air-pollution-may-strengthen-global-warming/
Personal expenditure is a reasonable proxy for damage done:
Action is hard because this is a complex problem that will radically change peoples lives:
We need a plan that is acceptable to all:
What you can do to can help (but not fix) in rough order:
Don't believe that it will be easy to halt global warming, (e.g. 100 solutions to reverse global warming) - not only have we made no progress in reducing emissions so far, we are continually making things worse. We've failed so far and don't even have a good plan for efficient action before it's too late. Go back to this calculator and see if you can personally hit the target.
If you think I've been overly pessimistic, remember that halting global warming is the easy problem. Getting to carbon neutrality does nothing about the poisons we've already released. The warming that has already happened could release a lot more greenhouse gasses from melting tundra, the loss of the Arctic ice cap will result in more warming because snow reflects sunlight well, and the carbon dioxide that has entered our oceans is causing acidification and killing coral reefs. Even if we could go way beyond carbon neutrality to a magical zero emissions we have to tackle the significant problems we've already created. These could easily add as much global warming as we've already seen (e.g https://www.scientificamerican.com/article/cleaning-up-air-pollution-may-strengthen-global-warming/) so it could well be too late to avoid catastrophe - that doesn't mean we shouldn't act now.
To end, here is a big question: Is global warming and individual or institutional responsbility?
