Ice sheet melt on track with ‘worst-case climate scenario’
Mass-loss rates of ice sheets in Greenland & Antarctica have been rapidly increasing
A recent report confirms that ice sheets in Greenland and Antarctica, whose mass-loss rates have been rapidly increasing, are matching the Intergovernmental Panel on Climate Change's worst-case sea-level rise scenarios.
The study, published in Nature Climate Change, compares ice-sheet mass-balance results from satellite observations with projections from climate models. The results come from an international team of scientists from the University of Leeds (UK) and the Danish Meteorological Institute (DMI), who are also part of the ongoing Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE).
IMBIE is an international collaboration between scientists, established in 2011 as a community effort to reduce uncertainties in different satellite-based measurements of ice sheet mass balance, and is co-funded by ESA and NASA.
IMBIE is supported by ESA's EO Science for Society programme and ESA's Climate Change Initiative, which generates accurate and long-term satellite-derived datasets for 21 Essential Climate Variables, to characterise the evolution of the Earth system.
