Two degrees Celsius: That's the global temperature increment scientists say the world must stay beneath to avoid the worst effects of climate change. But according to a study published this week in the journal Nature Climate Change, the odds of us staying under this threshold are looking pretty grim.
The study, which looked at carbon use, population trends and the projected economic growth of 150 countries, forecast only a 5 percent chance that warming would be limited to 2 degrees above pre-industrial levels by the year 2100.
"We're closer to the margin than we think," lead author Adrian Raftery, a statistics professor at the University of Washington, told the Guardian this week. "If we want to avoid 2 degrees Celsius, we have very little time left. The public should be very concerned."
