This May be the End of Global Warming...for Now!

Engineers have come up with a new way of potentially removing harmful gasses from the air. The process of sequestration involves getting rid of CO2 from our atmosphere by pumping it either underwater or deep under the ground. The idea is that under high pressure CO2 turns into a liquid, and once this happens it takes up less space and should remain underwater or underground for an indefinite period of time (we’re talking potentially thousands of years). Norway has already been doing this for many years.
The concerns are clear: Exactly how much time constitutes “and indefinite period?” How will this affect the animal and plant life on the sea bed? And how will people feel living and building communities on a ground ballooning with harmful gasses? It has the sound of a ticking time bomb, but perhaps this would buy us some time to fix our past mistakes and move towards a more sustainable world.
What do you think?

Carbon sequestration does show promise, but it has not yet been demonstrated on a large scale. We are talking about disposal of billions of tons of CO2.
In addition, the neighborhood near one of these sites may protest just as with other waste disposal facilities. My guess is that Greenpeace would fight to prevent carbon storage in subsea caverns or deep ocean storage. It will be interesting to see how these conflicts get resolved (assuming the scale question is resolved too).
