If we keep going the way were going, we’ve had it. And even if we follow the Paris agreement and try to reduce emissions, we’ve still had it, because we wouldn’t be reducing carbon dioxide fast enough. The only way we can save ourselves is to remove carbon dioxide from the atmosphere… that would be a very expensive business… the greatest the human race has ever undertaken, but we need to do it to save ourselves. If an asteroid was headed for the earth, people would deploy ever ypossible thing despite the massive costs being incurred. We have to wake up to the fact that that is what the human race has got to do.
