Thanks for the link, David Walters. Here it is again: https://vimeo.com/80518559 Very interesting. All of Peter Byck's videos make a lot of sense. Painting roofs white, installing solar panels, recycling energy, putting windmills on farms, etc., are all great ideas and I am all for it. But all this together will not bring down our carbon emissions quickly enough. We also have to reduce our footprint by consuming less. Here is another remark regarding sequestering carbon in top soil. We should not think it is ok get more coal, oil, and gas out of the ground because we can then sequester the carbon in top soil. In the long run, this sequestration is unreliable. Right now, a lot of carbon gets released because of peat fires in Indonesia and thawing permafrost in the arctic. All this is carbon sequestered in top soil which is finding its way back into the atmosphere. This is one of the reasons why GHG concentrations in in the atmosphere are still accelerating, although fossil fuel emissions have been declining. (Another reason seems to be that the warming oceans are absorbing less CO2). We have no choice but leaving the carbon safely sequestered far below ground where it is right now. Digging it back down into equally safe permanent repositories is going to be incredibly expensive.
