This is how much we can cool the planet by burying carbon underground
There’s a big question hanging over the global fight against climate change: Just how much carbon dioxide can humanity bury?
To stave off the drought, famine, poverty and deadly disasters that come from overheating the planet, people need to stop putting greenhouse gases into the atmosphere. But at this point, we’ve already polluted the planet so much that — even in the best case — experts say we will shoot past safe temperatures and then have to slowly turn the planet’s thermostat back down by removing carbon dioxide from the air and storing it somewhere.
