1-You are right! The world is not going to end soon. You are.
Estimates of the end of the world are about 4.5 billion years from now, before the sun goes red-giant.
Global Industrial Society as we know it on the other hand is another story.
2- Soon? Depends on what the definition of "is" is as one former President famously declared. . Homo sapiens has been around for 300,000 years. I think 2100 is as close as tomorrow but hey, that's me. You might be dead and gone but the planet will still have billions of suffering people, actual people.
3- This is ACTUAL SCIENCE: https://www.ipcc.ch/report/sixth-assessment-report-working-group-ii/.
over 14,000 studies from 66 countries, vetted and watered down by politicians who are saying the same thing you are: not convinced.
I don't know how much more actual science you'd like but remember denial is a powerful tool.
Actual science can not be the science that gives you the answers you want. You might want to read the IPCC reports.
Education begins at home.
4- Complex systems have feedback loops. Trying to convince anyone that "climate is going to hell" independent of social divisions, inequality etc. makes as much sense as separating "dental care" and "vision" from overall health insurance.

6- I would suggest you are not convinced because you have not experienced.
Alok Sharma was convinced at the end of the useless gathering called COP-26 and was close to tears, I wonder what convinced him?
Ask yourself : if you were "convinced" what would you do differently, how threatened would you feel?
How invested are you in not being convinced? How invested are you in perpetuating the madness we called Industrial "civilization" which overwhelmingly favors the wealthy West?
