From: Geoengineering the Climate (2009) Click to enlarge. It is an unpalatable truth that unless we can succeed in greatly reducing CO 2 emissions we are headed for a very uncomfortable and challenging climate future, and geoengineering will be the only option left to limit further temperature increases. Professor John Shepherd.
Lead author Kharecha and colleagues note that current climate science indicates that atmospheric CO 2 concentrations, already at 387 ppm in 2009 and rising, need to be reduced to no more than 350 ppm. Tags: Carbon Capture and Storage (CCS) ClimateChange Coal Emissions Nuclear Policy.
Our planned demonstration is the first attempt at proving that we can simultaneously mitigate greenhouse gas induced climatechange and generate clean baseload power using geothermal energy. Our approach relies on this gradual loss as a way to store a power plant’s CO 2 underground rather than emitting it into the atmosphere.
Capturing CO 2 emissions from large power and industrial plants and putting it to beneficial use or storing it in deep geologic formations is a key element in national efforts to mitigate climatechange, DOE says.

In December 2009, the EPA Administrator found that the current and projected concentrations of greenhouse gases endanger the public health and welfare; one year later, EPA announced a proposed settlement agreement to issue rules that would address GHG pollution from certain fossil fuel-fired EGUs.
The United States remain one of the largest emitters of CO2, with 17.3 tonnes per capita, despite a decline due to the recession in 2008-2009, high oil prices and an increased share of natural gas.

From an environmental perspective, such a process would have tremendous benefits in reducing the impact of anthropogenic CO 2 on climatechange and would eliminate the emission of sulfur and nitrogen compounds that are readily produced from the combustion of petroleum-derived fuels.
