Dr. James Hansen, the former NASA scientist who is widely credited with being one of the first to raise concerns about human-caused global warming, is a co-author of a new report predicting that the world will undergo devastating sea level rise within mere decades—not centuries, as previously thought.
The report, published Tuesday in the open-access journal Atmospheric Chemistry and Physics, paints an even bleaker picture of the planet’s future, positing that continued high fossil fuel emissions will “increase powerful storms” and drive sea-level rise of “several meters over a timescale of 50 to 150 years.”
Hansen, who now serves as the director of the Climate Science Awareness and Solutions program at Columbia University Earth Institute, published the findings along with an international team of 18 researchers and academics.
