A warm... ending?
Daniel Schrag
Professor of Earth and Planetary Sciences, Harvard University
“This is an experiment on the earth's climate, on the earth's atmosphere that hasn't been done for millions of years, and the choices we make in next few decades are really going to determine how far outside the human experience we're willing to push our planet. I really hope we don't end up at 1,000 parts per million of carbon dioxide, because I think there are going to be many surprises there that none of us are going to be able to predict.
"But most importantly, that the uncertainty, the fact that we don't know exactly how a planet works at a 1,000 parts per million – that is the problem. That is not a reason for inaction. That is the whole reason for doing something about it because we don't want to just try this out – we only have one planet that we can live on.
"The view from the Rovers on Mars is pretty interesting, but its no place I'd like to spend any time."
