Your reaction surprises me. What is so strange about "preparing on the community level", which would mean things like making sure your township is not expanding into areas that would be destroyed by newly severe forest fires or hurricanes or floods. Or that your city forbids certain types of lawns or agriculture because droughts are getting more severe. Or just having a more independent electricity/water/sewage in your house because the municipal systems do not have the backups they will start needing.
All the things you describe are good and beneficial for society. The problem was that you are preparing for an "impact" in 10 years that is not being predicted by anyone, except doomers and propagandists. You believe that the BBC is "neoliberal propaganda". That is your right, but you will alienate the vast majority of people with such extremist rhetoric.
Slow down for a second, I am not the person to whom you originally responded, I am just a passerby that is surprised by the intensity of your reaction given there are fairly reasonable interpretations of the passage you quoted as a reason to not bother having conversation with OP. We do know that droughts and fires and hurricanes will be more severe over the next decade or two, so it seems reasonable to call it "impact", their severe dislike of BBC notwithstanding.
