Climate scientist Radley Horton is bringing the effects of sea level rise to decision-makers, and fostering discussions to help society confront climate change.
An international collaboration will study the wasting of the Thwaites glacier, which already accounts for around 4 percent of current global sea-level rise, and could collapse within decades or centuries.
Findings from last year indicate that the Greenland Ice Sheet is perhaps not as stable as scientists had hoped.
