Climate expert issues dire warning

NASA’s former climate chief has issued a stark new study that finds that the world’s current climate goal could be inadequate and may not prevent catastrophic losses from rising seas, ocean temperatures and changes in global weather. But the extreme nature of his projections has some scientists questioning the methods he used and the results he reached.

Global leaders and scientists have agreed that keeping global warming to within 2°C of pre-industrial temperatures represents a safe level of climate change. The new findings, published as a discussion paper in the European Geophysical Union’s Atmospheric Chemistry and Physics journal, indicate something else. They show that 2°C of warming could lead to runaway ice melt at the poles, causing sea level rise and ocean circulation changes by 2100 that are much more extreme than most current projections.

A new analysis from a climate change organization estimates which coastal countries can expect the most regular flooding by the year 2100.
