While this is aggravating, the COP in Dubai will not have that much effect on global warming. The sad fact is that there are demographic and economic factors that will make timely action quite unlikely. First, the earth can support only about 2 billion people at most, SUSTAINABLY (with 100% recycling) - so there are 6 billion of us above that level, which guarantees continued degradation of the planet. Second, there are 1 billion existing cars and trucks that burn fossil fuels, and there is not enough money or materials to replace them with electric vehicles - this is a problem that should have been dealt with a generation ago, but wasn't. Third, there are significant problems with replacement technologies - apparently the companies working on modular nuclear power plants to replace decommissioned coal and gas fired generating plants have stopped their work because funding is limited and the numbers don't work for them anymore. We need Manhattan Project levels of government research into basic energy materials, and even more important, major basic research in scaling up the experimental processes for mitigating and sequestering CO2 and methane as they appear, as we did for sulfur dioxide in emissions from power plants. And we have to hope that James Hansen is wrong in his latest paper..... Reality may be a bitch, but we do have to deal with it.

We need to make a solar shield and put about 1/15 of the Earth in the shade also. In order to reduce human suffering.

To cause human suffering is to serve evil. With no conscience, the right has no problem with it. Being raised as a narcissistic animal has its good points for them-selves, screw everyone else. Their mothers, their fathers, their sibling's, their children, they're great-grandchildren and their pets, so why would they care about their neighbor?

A solar shield does not have to be that large. Shine a light on your hand, and check the shadow it casts, now move your hand away from the wall or surface, keeping the light source at the same distance from the hand, and the shadow grows larger.

But that brings up another problem. If the shield is in a geosynchronous orbit like GPS and Communication satellites, that part of the planet will be in perpetual shadow and that would adversely affect vegetation, but would cool that portion of the earth under it's shadow. If you wanted a shadow that moves as the "World Turns", then it has to be in very high orbit and in synch with the sun, and the sun is moving through the galaxy, so we are talking of solar synchonous orbit., and one that moves with the sun That way the shadow moves with the rotation of the Earth., like an eclipse.

Or do I have that wrong, just a thought experiment.

Edit added: My hand raced against my brain, and I misspoke. I said keep your shadow, the same distance from your hand, I meant light source and corrected

My expertise in the field is driving a truck. It is thoroughly lacking a lot of education. I think we need to put the equator in the shade to get the most advantage out of it? Those people could use a little bit of shade down there, I bet their trees would still grow back?
