I'm slowly coming to the conclusion that the only way to avoid CO2 planetary poisoning will be new technology - both non-carbon energy-creating (nuclear is the obvious first choice) and carbon capturing. Some good news on the latter front:
The prototype so-called scrubber will be small enough to fit inside a shipping container. Lackner estimates it will initially cost around £100,000 to build, but the carbon cost of making each device would be "small potatoes" compared with the amount each would capture, he said.
The scientists stress their invention is not a magic bullet to solve climate change.
It would take millions of the devices to soak up the world's carbon emissions, and the CO2 trapped would still need to be disposed of. But the team says the technology may be the best way to avert dangerous temperature rises, as fossil fuel use is predicted to increase sharply in coming decades despite international efforts. Climate experts at a monitoring station in Hawaii this month reported CO2 levels in the atmosphere have reached a record 387 parts per million (ppm) - 40% higher than before the industrial revolution.
