The world could lose up to 80% of its glaciers this century. That's one finding of a recent paper co-authored by a University of New England researcher. The paper published this week in the journal Science shows that the best-case scenario is that half of all glaciers, and a quarter of all glacier mass, will melt by 2100. That's assuming that mean global temperature is limited to 1.5 degrees Celsius of warming. Co-author Will Kochtitzky, of the University of New England, says the research team compiled observations and ran models to understand how climate change might affect glaciers. At current temperature projections, the analysis shows that melting glaciers will likely add 4 inches of sea level rise by century's end. Kochtitzky says this will amplify tidal surges in Maine like those from the storm just before Christmas.
