The planet and even our global technological society will survive global warming, but our coastlines and coastal cities won't. Our only hope of stabilizing things is to slow down and stop emitting carbon ASAP and reduce methane emissions as much as we can, though methane is worse for greenhouse effects, it doesn't hang around like CO2 does. If we can go green for most things like transport, steel and concrete production, then we can slow things down enough so our increasing technological power can address it over time. Technologies like carbon capture or space borne geoengineering as a temporary expedient could be used to mitigate the effects until we can bring things back into balance. Technology got us into this mess, and it is the only way out of it while maintaining a global civilization and avoiding environmental and humanitarian catastrophe.
Everybody going "back to the land" won't help or work, except for a few to survive. Individual responsibility helps, but many don't give a fuck and never will, so government action and incentives are required too. The biggest impact is made by the profit motive, the economics of the situation and solar at least has gotten a lot cheaper than coal for power generation for instance. It has gotten so cheap, even domestic grid users are making their own. It is making economic sense from industry and utilities down to homeowners and local microgrids, capitalism and competition can do the rest very quickly. For solar to really take off however we need cheap batteries too, and they are on the way with price competition in that market as fierce as in the solar market.
Time is running out to prevent sea levels from rising to dangerous levels, which could displace hundreds of millions of people living in coastal areas, a report warns.
