Supercritical solution for global warming...

An article about CO2 capture and storage has been published in Nature Geoscience recently [1]. The storage of the CO2 is said to be in supercritical state, however only the pressure is above the critical point and therefore the system is not fully supercritical but in a compressed liquid state [2].
Geological carbon storage

Storage of the carbon dioxide that is produced by burning fossil fuels is one way to avoid the damaging consequences of climate change. A range of observations suggests that geological carbon storage is much less risky than unabated carbon emissions to the atmosphere.
