Though governments have agreed to try to limit global warming to no more than two degrees Celsius above pre-industrial levels, a paper by James Hansen et al. in Atmospheric Chemistry and Physics finds that goal may not prevent major changes on an irreversible and unadaptable scale. Studying the last interglacial period, about 120,000 years ago, when the temperature was less than one degree Celsius warmer than today, Hansen et al. estimate sea level was six to nine meters higher than today.
