80% of Earth’s glaciers may be gone by the end of the century if investment in fossil fuels continues.
The authors, led by David Rounce, an assistant professor of civil and environmental engineering at Carnegie Mellon University in the US, wrote: ‘Every increase in temperature has significant consequences with respect to glacier contribution to sea level rise, the loss of glaciers around the world, and changes to hydrology, ecology, and natural hazards.
The findings suggest that glaciers are projected to lose 26% to 41% of their total mass by 2100, based on temperature rises of 1.5C to 4C respectively. Based on the current climate pledges by governments around the world, it is estimated global mean temperature will rise by 2.7C by 2100.According to the researchers, this means smaller glacial regions like Central Europe and Western Canada and the US are at risk of disappearing.
Professor de Elvira added: “All existing evidence is consistent with the results of this paper, and the authors have taken into account the possible limitations of their models and calculations.”He also said the study makes much of the earlier partial data more concrete.
