Sentences with phrase «current ice mass loss»

The basal melting due to subsurface warming represents an important component of the current ice mass loss,» Ezat points out.

Not exact matches

While we are within this range, our current understanding of ice - mass loss is adequate.

and therefore to be able to make a stronger statement on how unique the current and apparently global warming related ice mass loss is» for Greenland, he says.

Our modelled values are consistent with current rates of Antarctic ice loss and sea - level rise, and imply that accelerated mass loss from marine - based portions of Antarctic ice sheets may ensue when an increase in global mean air temperature of only 1.4 - 2.0 deg.

SLR by 2100 is more likely to come from ice mass loss from West Antarctica (WAIS) where warm ocean currents are already melting ice at glacier mouths and attacking areas of the WAIS resting on the seabed.

For Antarctica as a whole, the study found the current rate of ice sheet mass loss to be about 160 billion metric tons of ice per year.

Consider the facts: the climate system is indicated to have left the natural cycle path; multiple lines of evidence and studies from different fields all point to the human fingerprint on current climate change; the convergence of these evidence lines include ice mass loss, pattern changes, ocean acidification, plant and species migration, isotopic signature of CO2, changes in atmospheric composition, and many others.

Great progress has been made recently in assessing the current rate of mass loss from the ice sheets (Shepherd et al., 2012), as well as monitoring the changing snowfall, surface melting, and temperature contributing to the changes.

Current total ice - loss in Greenland is running at an estimated 200 Gte / yr and Antarctica at 150 Gte / yr (with ice mass gain in the east and loss in the west — with some estimates of a net gain)-- at that rate of 1mm / yr, by 2100 the global ice - loss would raise sea level by a little over 3 inches.

Current models suggest ice mass losses increase with temperature more rapidly than gains due to increased precipitation and that the surface mass balance becomes negative (net ice loss) at a global average warming (relative to pre-industrial values) in excess of 1.9 to 4.6 °C.

Thirteen years of GRACE data provide an excellent picture of the current mass changes of Greenland and Antarctica, with mass loss in the GRACE period 2002 - 15 amounting to 265 ± 25 GT / yr for Greenland (including peripheral ice caps), and 95 ± 50 GT / year for Antarctica, corresponding to 0.72 mm / year and 0.26 mm / year average global sea level change.
