> We're still a long way from pulling off the sequestration that's actually needed at the scale that's needed.

How so? The simple fact that natural gas and oil still exists, when it comes from 100 million year old biomass, proves beyond a shadow of doubt that geological sequestration holds its integrity at geological timescales.

We have also been injecting CO2 at a rate of 1 million tonnes per year at the Sleipner field in the North Sea since 1996, and extensive 3D timelapse seismography shows the CO2 is permanently trapped.

Think about that - we have been demonstrating CO2 storage at scale since before the launch of the first Palm Pilot.
