Sorry, this is too vague for me...humanity as a civilization "could be wiped out", well of course we could. If a meteor hits us or we accidentally and/or intentionally set off a bunch of nuclear weapons...yes, we "could" be wiped out. But will climate change, a long-run issue, wipe out humanity in 15? I don't think even pessimistic forecasters are predicting that 2034 will be the end of civilization due to climate.
