This week Nicholas Stern, the British top climate economist and academic who is probably most known for the Stern Review, endorsed 350 ppm as â€œa very sensible long-term target.â€
350 ppm, as in parts per million, the level scientists have identified as the safe upper limit for CO2 in our atmosphere. We are currently at 390 ppm and, according to the science, we need to get back to 350 ppm as soon as possible to be able avoid runaway climate change.
In an interview with a German newspaper Stern endorsed the 350 ppm target saying he â€œthink it's a very sensible long-term target." Bill McKibben, environmental writer and founder of 350.org, writes:
McKibben says "Stern is right" and that his endorsement will "help stiffen the push for real measures" at the climate talks in Copenhagen this December.
