The Dilemma Over Coal Generated Power - CBS News
(CBS) The future of our climate might be summed up in one question: what do we do about coal?
...
But here's the brutal part: coal is twice as dirty as natural gas and puts more carbon dioxide in the air than all of our cars and trucks. In short, we're caught between a rock and a hot place.

But Jim Hansen, NASA's top climate scientists, says 2050 is too late. "We will have guaranteed disasters for our children, grandchildren, and the unborn," he said.
Hansen is credited with some of the earliest and most accurate projections of climate change. He thinks Roger's plan leaves the Earth in the oven decades too long.
"We are going to have to phase out emissions from coal within the next 20 years if we hope to prevent climate disasters," Hansen told Pelley.
"Are you saying we can't build any new coal fired power plants in this country?" Pelley asked.
"Absolutely, not only in this country, but in the world. This is not yet understood. We are going to have to have a moratorium on new coal-fired power plants within the next few years and phase out the existing ones over the next 20 years or so if we have to preserve the climate like the one that has existed the last several thousand years," Hansen said.

Joe Romm thinks a trillion dollars might be optimistic. Romm ran alternative fuel projects in the Clinton administration.
He says the amount of CO2 we're talking about is mind-boggling. "If the world did this at scale, it would be the equivalent amount of CO2 going into the ground as oil now comes out of the ground. So you have to recreate the entire oil delivery infrastructure of the planet, which was built up over a century, just to deal with this CO2," he explained.

President Obama wants to speed up cleaner technologies by taxing utilities for the carbon they produce. But the idea is meeting some stiff resistance in Congress.
