La Tierra ha perdido 28 billones de toneladas de hielo desde 1994

August 26, 2020 - La Tierra perdió 28 billones de toneladas de hielo entre 1994 y 2017, el derretimiento del 60 por ciento ocurrió en el hemisferio norte, según datos publicados en la revista en línea Cryosphere Discussions.

Scientists from Leeds and Edinburgh universities and University College London combined satellite observations and numerical models to identify the impact of global warming.

The group of researchers describe the ice loss as “staggering” and warn that melting glaciers and ice sheets could cause sea levels to reach a meter (3 feet) by the end of the century.

The analysis showed that the rate of ice loss has risen by 57 percent since the 1990s – from 0.8 to 1.2 trillion tonnes per year – owing to increased losses from mountain glaciers, Antarctica, Greenland, and from Antarctic ice shelves.

The majority of all ice losses were driven by atmospheric melting, with 68 percent from Arctic sea ice, mountain glaciers, ice shelf calving and ice sheet surface mass balance. The remaining 32 percent of the losses were from ice sheet discharge and ice shelf thinning, driven by oceanic melting.
