Idk. Folks much smarter than I seem worried so maybe I should be too but it just seems like such a long shot.
What are your timelines here? "Catastrophic" is vague but I'd put the climate change meaningfully affecting the quality of life of average westerner at end of century, while AGI could be before the middle of the century.
We have surpassed the 1.5°C goal and are on track towards 3.5°C to 5°C. This accelerates the climate change timeline so that we'll see effects postulated for the end of the century in about ~20 years.
Likewise, the cloud seeding they seem to be doing nearly worldwide now - the cloud formations from whatever they're spraying - are artificially changing weather patterns, and so a lot of the weather "anomalies" or unexpected-unusual weather-temperatures could very easily be because of those shenanigans; it could very easily be as a method to manufacture consent with the general population.
Similarly with the arson forest fires in Canada last summer, something like 90%+ of them were arson + a few years prior some of the governments in the prairie provinces (e.g. hottest and dryest) gutted their forest firefighting budgets; interesting behaviour considering if they're expecting more things to get hotter-dryer, you'd add to the budget, not take away from it, right?
I'm sorry, do you have a source for that claim? You seem to dismiss the video without any evidence.
