Air Capture Update

I have a short, invited correspondence in the current issue of Nature Geoscience on air capture. Here is how it begins:
The world is struggling to reduce greenhouse-gas emissions through conventional mitigation, and initially high expectations for the United Nations Climate Change Conference (Copenhagen, 7–18 December) are seemingly being scaled back almost daily. It thus seems that brute force efforts to remove and sequester carbon dioxide, such as air capture, will come to occupy an ever greater role in climate-policy discussions. Air capture refers to the direct removal and sequestration of carbon dioxide from ambient air. Investigations of the technologies that would remove this carbon dioxide, along with the associated costs and benefits, are attracting growing attention.
This issue is focused on carbon sequestration has a range of articles worth a look.
