A new study by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of California, Irvine, shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth's continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent.

(1) One is the ice sheet and glacier mechanical collapse, which doesn't require a whole lot more warming, but will happen with some set minimum amount of warming over some time period; and (2) the other is global warming that keeps increasing beyond the level needed to cause # 1, which among other things will perhaps lead to positive carbon feedbacks (e.g., from melting permafrost and hydrates).

That has caused glaciers, ice caps, and the vast ice sheets in Greenland and Antarctica to melt and break apart.

This warming is causing an extraordinary increase in the melting of glaciers and the Greenland Ice Sheet that led scientists earlier this year to project a sea level rise of between 0.9 and 1.6 meters by the end of the century.

«This warming is causing the swift increase in the melting of glaciers and the Greenland Ice Sheet that led scientists to project a sea level rise of between 0.9 and 1.6 meters by the end of the century.

Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice of the East Antarctic Ice Sheice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice of the East Antarctic Ice Sheice of the East Antarctic Ice SheIce Sheet.

The carbon pollution we continue pumping into the atmosphere is already causing our air and oceans to warm, glaciers and ice sheets to melt, and sea levels to rise at alarming rates.

The retreat of glaciers and shrinking of the Greenland ice sheet in the Arctic, for example, is predicted to cause significant sea - level rise, changes in the salinity of our oceans, and altered feedback loops that will make the Arctic warm up even faster.

Glaciers and ice sheets are rapidly melting, causing sea levels to elevate, but not fast enough.

It is causing polar ice sheets and glaciers to melt; and sea levels to rise.

Sea level rise is caused by the ocean expanding as it heats up due to global warming and as major stores of ice from glaciers and ice sheets melt.

Sea levels around Britain could rise by more than one metre (3ft) due to climate change, according to a new assessment of melting ice sheets and glaciers, causing floods in London and other coastal towns.

According to the study, this is because of the expansion of warming waters, which caused as much sea level rise from 2002 through 2014 as the melting of all the glaciers and the Greenland and Antarctic ice sheets combined.

Joughin and others, 2008 observed that seasonal drainage of meltwater to the glacier bed induces a uniform acceleration of 50 — 150 meters / year over a ~ 300 km long section of the West Greenland margin that is not drained by outlet glaciers, causing a large fractional acceleration of the interior ice sheet but a small fractional change in the speed of fast - moving outlet glaciers.

Fluctuations in the mass of the Greenland and Antarctic ice sheets are of considerable societal importance as they impact directly on global sea levels: since 1901, ice losses from Antarctica and Greenland, alongside the melting of small glaciers and ice caps and thermal expansion of the oceans, have caused global sea levels to rise at an average rate of 1.7 mm / yr.

The rise was caused partly by the simple thermal expansion of sea water under the influence of global warming, and increasingly by the melting of glaciers and ice sheets.

Presenting such alternative figures confuses and undermines the public understanding of the actual science, which is an understanding about the driving mechanisms of sea level rise: thermal expansion of ocean water, melting of mountain glaciers and complex dynamics of large ice sheets — in correspondence again with projected temperature rise, that is in turn a product of projected rises of greenhouse gas concentrations using calculated estimates of climate sensitivity, together creating a net disturbance in Earth's energy balance, the very root cause of anthropogenic climate change.

The principal causes are clear: global decline of land ice (mountain glaciers & ice sheets) and thermal expansion of ocean water (water expands as it becomes warmer).
