I'm concerned, bought an EV and a Hybrid, largely for tax/ cost reasons but I'm very happy they're better for the environment, even if just as an early adopter it helps drag other people away from fossil fuels then even better. Bought a new house (not near any water), which has a few solar panels and is well insulated, and the next step is more panels and a battery and I would be more than happy to outlay on that, even if I only got my money back in 5-10 years and was even after that.
My concern is I think we're passed the point of no return, in so far as things will take 10-20 years to sort out and get greener, but by then it will be too late anyway and the climate will run away with itself. Obviously, we have no control over developing nations and have zero right to tell them not to use cheap fuel, as our entire nation was largely developed in the same way through coal and cheap steel production, we paved the way to this mess, literally.
We need to start the process of preparing for rising sea levels, and need to get people moved away from vulnerable areas as it's going to take 50-100 years to build the houses and infrastructure to accommodate that.
We need to go to renewable energy though, and to EV's etc, regardless as to what anyone thinks, as we have next to no oil and gas of our own, and developing nations will increase demand for it, as it runs out, so we're ****ed on that in two ways. Also, all the cheaper oil and gas fields have been bled dry, all that is left is the harder-to-reach areas, which will inevitably cost more.
Sure, the climate has changed over time (usually takes thousands of years), and we were daft to not think it wouldn't (ignorance isn't bliss) but there's zero doubt that we're massively responsible for the recent rapid recent increase in temperature. It's directly related to CO2 which we've been a massive cause of, and we had the tech to really slow down the problem decades ago, which would have saved us in so many ways, especially for the future.
We need to be building as many flood and sea defences, as much as we're building renewable energy. The flood and seas defences will ultimately be money down the drain, literally, but it would buy time, which we're going to need.
It's mad that there are housing developments being built near sea level, and additional infrastructure to support that. It's also mad that people buy the existing neighbouring houses as prices in such places will end up worth nothing. The house will be underwater, and there's next to zero value in land underwater. Fair enough people might only plan to live in them for 10-30 years, but who do they think is going to buy them off them, in 30 years etc?
It's mad that for the last 20 years, we've been building houses based on 1 in 100-year storm events, when future storms are going to be much more common, and much worse (as are the periods of drought, which then amplify the problems a normal storm would cause).
It's mad that we allow any development near existing watercourses, which would prevent the existing watercourses from being widened, or we do daft things like widen in some areas, but have no interest in looking at where the future pinch points for water would be.
