The Absolute Worst Climate Change Solution Possible

There is no such thing as global warming. If the north gets warmer, the south gets cooler. The north, however, has gone past the tipping point. See the recent article on the Barents Sea where they found that not only does the Gulf Stream warm the sea (which is what affected polar ice and generated the current 110 degree temperature spikes), but also warming by air. We are in a negative feedback loop and there is only one solution, cool the air in Europe and especially in Boston to Richmond Megacity. It is one big strode with as many people as live on Java. This hot zone has done us in - since now the warmth from the Southwest will also go north through Canada to the Barents Sea and may melt Greenland in the process.

Turns out, the problem was never Carbon Dioxide, it was urban heat. We need to literally ban cars in urban areas and replace them with tethered electric vehicles that are linked to roofs above. The roof deck will have to be covered in grass, with irrigation streams and solar panel coverage (to run pumps to manage water in the system. We cannot use coal to power it - small reactor nuclear is both safe and reliable.

Barents Sea temp has gone up one degree per year (centigrade - 2 farenheit) for decades. Warming the atmosphere or the average global sea or land temp are irrelevant concepts. We heated up the water that heated up the Arctic past the point of no return - or at least no return to normal. Petroleum companies will resist the solution - but we have human suffering gong for us in Arizona and the Southwest. Also the South Central. Refineries will not be able to operate at the kind of cost that allows for the profit margins of Big Oil. 

The price of gasoline is fairly inelastic until it is not anymore. 110 degree plus temperatures get us to the kind of elasticity that parks cars on an individual basis. We have to shift any car that can be tethered to the electric grid, both in urban areas and highways. Gasoline can only be sold where tethering is not technically feasible.

This is not an if solution, it is a when.

As for building a Dyson sphere or any of that nonsense, there are plenty of higher level planets to be reincarnated to, if the people who have had Near Death Experiences can be relied on. Most of us are likely from one of them in one life or another. If people want advance tech, don't come back to earth in your next life.  According to some, the question of how many civilizations are more advanced than us is answered with "all of them." We cannot even agree amongst ourselves that God in not an asshole. It is more important to our evolution as a species in the galactic community than becoming "warp capable."
