I agree, there is a big defeatist and regressive narrative. But some of us do focus on the positive -- we can fix this, and fix a lot of other problems at the same time, and it's not even that costly if we do it right, gradually switching our energy sources over time and gradually changing our living habits where we're willing. People always talk about a carbon tax, because it's a really, really good idea: it is very economically efficient, is targeted like a laser at the real problem, and will have huge benefits even just in terms of reducing premature deaths from particulate pollution.
The reason I think stopping use of fossil fuels is really the only reasonable solution, or is at least a necessary part of any solution, is that anything else is like trying to fix your car accelerating out of control by just driving around with one foot on the brake. Trying to balance the increased greenhouse effect by blocking sunlight might work a bit, but there are all sorts of ways it can go wrong -- it creates a moral hazard where everyone will have less incentive to stop using fossil fuels and thus continue making the root cause of the problem worse, and we have to keep doing it forever -- stopping means a sudden massive amount of climate change that people won't have time to adjust to. There are so many really easy ways that we can cut our emissions massively, with technology we have available today, with virtually no impact on our living standards. The rest will take some time and technological improvements, but it's all doable!
And I've not heard of any sort of heat dissipation geo-engineering ideas -- the only feasible way I know of to get the earth's heat dissipation back to normal is to take off this extra blanket of greenhouse gases we've put on it. Any sort of heat dissipation would have to transfer heat to the upper atmosphere without being absorbed by CO2, and I don't think there's any way we could do that at the scale required to have a noticeable effect.
