Because it's simply not a big deal.
Tell me one aspect of it that I should take seriously.
>ocean levels will rise
Yeah by like one fucking meter by the year 2100.
Who fucking cares, even most coastal cities tend to be several meters above sea level, not even 0.1% of land mass will be lost.
But even if the coastal cities would be flooded, it still wouldn't be a huge deal. We can relocate and build new cities along the new coastline.
>more natural disasters
No real evidence for that, see
https://ourworldindata.org/grapher/number-of-natural-disaster-events.
I had gone up until the year 2000, most likely related to more consistent reporting on natural disasters in third world countries, but it mostly stabilized after that.
It's unlikely that natural disaster increased 10fold in the past 100 years and then stopped increasing so they've probably just stayed consistant for the past 100 years.
>but they are more deadly
Wrong again, see
https://ourworldindata.org/natural-disasters.
Even in the case that disasters are more severe now (for which there is no hard evidence), we more than compensate for that by having superior technology for helping people in need compared to 100 years ago.
>it will get hotter and dryer and harder to cultivate the land
Then we will relocate to other places where it's colder now. Scandinavia, Greenland, Siberia, Canada, just some examples of vast places in which 90% is considered inhabitable due to the cold.
People need to stop being sentimental and realize that we've historically always been on the move. Stop crying about abandoned towns in southern Italy as if that shit was always meant to keep.
Be like your ancestors, quick to pack your bags and move to more habitable lands should the need arise. Sentimentality is not a virtue, man must be pragmatic at all times.
