Doesn’t matter. Corporate carbon emissions are causing global climate change, and that is a much bigger threat to us than anything that the Sun or ISIS can throw at us. Because Science!
Of course, corporate carbon emissions are culpable. It’s those dirty corporations again, just ask Bernie! What the really smart people know we need to do is adopt an efficient and just system like the Stalinist system in North Korea. That will save the earth because everyone will be eating tree bark and no one (except members of the ruling class) will be driving their SUV to a restaurant.
