Keeping the world below 2°C requires Technology we don’t have

This arstechnica article discusses the current state of alternate technologies to eliminate CO2 (GHGs) from the atmosphere. The crucial question: can carbon dioxide removal techniques be scaled up to the necessary level in time? A new European Academies Science Advisory Council (EASAC) report—reviewed and endorsed by the national academies of more than two dozen countries—evaluates the outlook for carbon dioxide removal. And it’s not optimistic. The report looks at a number of options, including reforestation, soil management, plankton fertilization, industrial CO2 capture plants, biofuels with emissions injected underground for storage, and even the boosting of bedrock weathering reactions.

The conclusion: If we cannot absorbe enough GHGs by 2050, the 2 degree emission scenarios are doomed.
