Yeah, I work in the ecology sector in the UK and have basically resigned myself to preparing for a ~3C future. I do everything I can myself (semi-vegan, with cheese being the hardest thing to find a swap for so far, but milk was an easy swap; solar panels installed on a south facing roof; hybrid car and can't wait to upgrade to electric but I know it doesn't make sense to replace until necessary; always vote with climate policies as my number 1 issue, etc etc) but it's becoming pretty clear that with the way the world operates things will only truly shift gears once the damage being done has a severe enough economic impact. And that seems to be somewhere between 3 and 4 degrees. Insurance companies have been saying 4+ degrees is about the point that things become uninsurable, so I think that's the limit society will decide is genuinely unacceptable to reach.
Of course, that's a lot of pain, death, and suffering for significant parts of the world to go through, all completely avoidable, so it makes me incredibly disheartened to think about. But that's genuinely the path we're on right now if you ignore the self-congratulatory speeches and look at the real action being taken. Net zero by 2050, for the vast majority of the countries pledging to meet it, is like promising to make someone a cup of tea in the next 60 seconds and then sitting down and putting your feet up while saying "you can't criticise me for inaction - I pledged that I'd make you a tea in 60 seconds, so therefore I must be working towards it." Most people are able to grasp that making a cup of tea in 60 seconds would be a herculean challenge, possibly manageable but you'd need to seriously rush to get that done, maybe even with a bit of technological magic on the kettle's behalf to help you get there. Reaching net zero by 2050 is similar to that, but to most people it's a far away enough date, and involving action and policies they don't really understand, that the lack of action to achieve that goal isn't apparent to them.
Gardening is a hobby I've become really passionate about (living in the UK), mostly for the wildlife. Putting a pond in and wildflower meadow, log piles and hibernacula, and seeing all the insects they attract, which leads to amphibians and bats etc showing up, this whole cascade of life from the improvements you're making, it's all really rewarding. But everything I add to or change in the garden is primarily with the consideration: "will this survive in 40C summers, droughts, and torrential winter rains?" I still see neighbours trying to make traditional garden staples like box hedging work and wonder how long it will take them to realize that even with today's level of climate change that's just not a plant species they can keep alive any more.
