This seems hyperbolic.
One scheme that has been suggested is to pump CO
2 deep into the ocean, where it would remain as a liquid. How much room is there on the ocean floor?
Another scheme that has been suggested is to pump CO
2 into saline aquifers:

Baseline Data Important for CCS Project's Planned 2011 Startup
Washington, D.C. — The recent completion of a three-dimensional (3-D) seismic survey at a large Illinois carbon dioxide (CO2) injection test site is an important step forward for the carbon capture and storage (CCS) project’s planned early 2011 startup.
The survey – essential to determine the geometry and internal structures of the deep underground saline reservoir where CO2 will be injected – was completed by the Midwest Geological Sequestration Consortium (MGSC), one of seven regional partnerships created by the U.S. Department of Energy (DOE) to advance CCS technologies nationwide. CCS is seen by many experts as a key technology for reducing greenhouse gas emissions and helping to mitigate potential climate change.
The project, located in Decatur, Ill., will capture CO2 from the Archer Daniels Midland (ADM) Ethanol Production Facility and inject it into a deep saline reservoir, more than a mile underground. Starting in early 2011, up to 1 million metric tons of CO2 from the ADM facility will be compressed to a dense, liquid-like state and injected over a 3-year period. The rock formation targeted for the injection is the Mt. Simon Sandstone, at a depth between 6,400 and 7,000 feet. The Mt. Simon Sandstone is the thickest and most widespread saline reservoir in the Illinois Basin, with an estimated CO2 storage capacity of approximately 30–110 billion metric tons.
...(And before you start, according to the DoE similar reservoirs exist near most point sources of CO2.)
But, hey, pursuing CCS is stupid right? I mean, no one in their right minds would suggest otherwise.

So-Called “Clean Coal” Technology Offers Promise Along with Considerable Risks, New Report Finds
Government Should Back Demonstration Projects; Nix New Coal-Fired Power Plants that Don't Capture and Store Carbon Emissions
WASHINGTON (October 15, 2008) – With domestic policy the focus of tonight's third presidential debate, the discussion likely will touch on energy and the future of coal, which currently generates about 50 percent of U.S. electricity. Both John McCain and Barack Obama have frequently mentioned their support for "clean coal" on the campaign trail, but neither one of them has fully explained what that means. Today, the Union of Concerned Scientists (UCS) issued a report that examines the pros and cons of a proposed technology that would capture coal plant carbon dioxide emissions and store them underground.
"We're on a collision course with a much hotter planet unless we drastically cut coal power plant emissions," said Barbara Freese, co-author of the report and author of the book "Coal: A Human History." "Carbon capture and storage holds promise, but we can't assume it will play a big role in cutting global warming pollution until we know whether it works at a commercial scale and what it will cost. In the meantime, we need to ramp up our reliance on energy efficiency and wind, solar and other renewable energy sources."
The United States has significant coal reserves and likely will continue to generate power from it for many years to come. Climate projections, however, indicate that the United States must swiftly cut carbon dioxide emissions and ultimately reduce them by at least 80 percent of 2000 levels by mid-century to avoid the worst consequences of climate change. Coal is the nation's largest source of global warming pollution, representing approximately a third of U.S. emissions, equal to the combined output of all U.S. cars, trucks, buses, trains and boats.
The UCS report, "Coal Power in a Warming World," proposes that the federal government fund five to 10 full-scale demonstration projects to test carbon-capture-and-storage technology's ability to cut coal power plant emissions. The report also calls for a halt in construction of new coal plants that do not capture and store carbon emissions, even though U.S. utilities are currently planning to build more than 100 plants without the technology. The country can meet its near-term energy needs and curb emissions, the report contends, using readily available renewable-energy and energy-efficiency technologies.

Statement from Environmental Defense Fund on House Carbon Capture Legislation

(Washington, DC - July 10, 2008) The House Subcommittee on Energy and Air Quality today held a hearing on H.R. 6258, a bill intended to spur the development and deployment of carbon capture and storage (CCS) technologies to reduce global warming pollution from coal-fired power plants.
EDF recognizes that coal will continue to be an important part of the U.S. energy supply for the foreseeable future, and that CCS technologies are needed to help electric utilities meet energy demands while protecting the climate. EDF believes the most effective way for Congress to promote the rapid commercialization and deployment of CCS technology is to create a market for it by enacting a national cap and trade program.

Figure 3.36: The value of improved technology.
Note: Modelling studies enable experts to calculate the economic value of technology improvements that increase particularly drastically with increasing stringency of stabilization targets (750, 650, 500, and 450 ppmv, respectively) imposed on a reference scenario (modelling after the IS92a scenario in this particular modelling study). Detailed model representation of technological interdependencies and competition and substitution is needed for a comprehensive assessment of the economic value of technology improvements. Left panel: cost savings (billions of 1996 US$) compared to the reference scenario when lowering the costs of solar photovoltaics (PV) from a reference value of 9 US cents per kWh (top) by 1, 3, 4, and 6 cents/kWh, respectively. For instance, the value of reducing PV costs from 9 to 3 cents per kWh could amount to up to 1.5 trillion US$ in an illustrative 550 ppmv stabilization scenario compared to the reference scenario in which costs remain at 9 cents/kWh). Right panel: cost savings resulting from availability of an ever larger and diversified portfolio of carbon capture and sequestration technologies. For instance, adding soil carbon sequestration to the portfolio of carbon capture and sequestration technology options (forest-sector measures were not included in the study) reduces costs by 1.1 trillion US$ in an illustrative 450 ppmv stabilization scenario. Removing all carbon capture sequestration technologies would triple the costs of stabilization for all concentration levels analyzed.
