United Nations climate chief Christiana Figueres said that coal power can be part of the solution to curbing global warming, but it would require shuttering older coal power plants, advancing carbon capture and storage (CCS) technology, and resolving to leave much of the planet’s existing coal reserves in the ground.

carbon capture and storage
Coal is a combustible sedimentary rock that has become the world’s most used energy source. Because it is so abundant and therefore cheap, much research has been done to see what other kinds of uses it can have other than direct burning for electricity production. The liquefaction of coal
Carbon Storage Projects Expanded in 2010 Despite Economic Challenges
written by Yale Environment 360
Twenty-one new carbon capture and storage (CCS) demonstration projects were launched worldwide in 2010, despite rising technology costs, according to a new report by Australia’s Global CCS Institute.
That growth represented a 10 percent increase from the previous year, and bumped the total number of projects active
Computer models that simulate and predict future climate change patterns are far from accurate according to climate scientist Kevin Anderson of the Tyndall Centre for Climate Change at the University of Manchester. Anderson believes that this is because the Integrated Assessment Models (IAM’s) that are widely used by
Each year energy-related carbon dioxide emissions account for more than 80 percent of greenhouse gas emissions in the United States. According to the Energy Information Association, that adds up to over 5,814 million metric tons (MMT) of carbon in 2008 alone. The Obama administration recognizes that this is not sustainable and that’s why we’ve actively sought to not only
Carbon dioxide air emissions is one of the big issues in global warming debate. However, before you start controlling by putting the carbon in the ground, you first have to put lawyers in a room to argue. After a year that saw billions of dollars spent around a variety of carbon capture and storage pilot projects, the focus in 2010 will shift from press conferences and engineering discussion to court cases and conference tables.
Everyone has an opinion on what is the right thing to do in global warming. Far from just an engineering decision the task of making technology an effective weapon in the fight against climate change will take a lot more than working out funding details and letting the engineers work.
Amid a growing call for reducing atmospheric concentrations of CO2 to 350 parts per million, a group of economists maintains that striving to meet that target is a smart investment — and the best insurance policy humanity could buy.
The climate change news from Washington is cautiously encouraging. No one in power is listening to the climate skeptics any more; the economic stimulus package included real money for clean energy; a bill capping U.S. carbon emissions emerged, battered but still standing, from the House of Representatives, and might even survive the Senate. This, along with stricter emission standards in Europe and a big push for clean energy and efficiency standards in China, provides grounds for hope for genuine progress on emissions reduction.
But while climate policy is finally moving forward, climate science is moving faster. One discovery after another suggests the world is warming faster, and climate damages are appearing sooner, than anyone had expected. Much of the policy discussion so far has been aimed at keeping the atmospheric concentration of CO2 below 450 parts per million (ppm) — which was until recently thought to be low enough to prevent dangerous levels of warming. But last year, James Hansen, NASA’s top climate scientist, argued that paleoclimatic evidence shows 450 ppm is the threshold for transition to an ice-free earth. This would imply a catastrophic rise in sea levels, eventually flooding all coastal cities and regions.
