Elon Musk just bought $100 million in publicity for the carbon capture industry

There is no way to stabilize the world’s temperature without an aggressive plan to pull carbon out of the atmosphere. The Intergovernmental Panel on Climate Change estimates than more than 3 to 7 gigatons (GT) of CO2 will need to be removed per year by 2050—up to 15 GT by the end of the century—to limit warming …
