Technology will play a role in affecting a perilous recovery, it won't in the way most technologists think. We don't have time to "invent a fix", we can't bank on having fusion power magically suck carbon from the oceans and skies at the last moment. Or a sunshade to prevent the tundra from erupting in methane.
Technologists can help organize (via online tools), educate and show (via charts, graphs, simulations). This is ultimately a social and political problem that requires the full force of governments. Individual efforts are largely symbolic. Not that we shouldn't do them, but convincing your legislators to enact real reforms is where we avoid life ending catastrophe. We can have a huge impact, we just have to find the areas where we can have a 1000:1 advantage vs a 1.5:1 advantage.
