I don't necessarily agree with GP's comment but they do have a valid point.

Everybody wants to solve the problem with technology. What if, the solution is just plain old hard work like planting trees, conservation, better recycling, better laws that help in saving ecosystem. But who would do that. So let's keep on creating problems with technology and then solve them with more technology.
Anything that facilitates or requires extracting carbon from the ground: Coal plants, petrol engines, cars, airplanes, mass production, modern agriculture processes.
The only way to stop global warming is to stop extracting carbon from the ground, where it's stored. After that we can think about capturing carbon. But first if all we need to stop pumping it into the atmosphere at a faster rate than the earth can absorb it (about 40% is absorbed at the moment, 60% of all human carbon use is added to the atmosphere).
Yes, what do you mean? The biggest climate effect at the moment is human carbon use, which is changing weather patterns, and the cause of the cloud shrinkage is changing weather patterns => cloud shrinkage is driven, to some degree (I would guess strongly, but let's be careful, so some degree) by human carbon extraction.
