At a major climate meeting in Poland, nearly 200 countries are trying to reach a deal on dramatically reducing carbon emissions. But a recent U.N. report found that may not be enough to avoid dangerous impacts from the warming climate. In fact, the world is falling so far short of what’s needed, it said, that it might be necessary to pull massive amounts of carbon dioxide out of the air.
The problem is that there’s no feasible — let alone economical — way to do that yet.
Our note: How about ‘olivine’?
