Also in the mid-1990s, another group of scientists proposed the now widely accepted mechanism for how lakes can form under glaciers: Heat radiating from Earth's interior is trapped under the thick, insulating ice sheet, and pressure from the weight of all the ice above it lowers the melting point of the ice at the bottom.

If Earth reaches dangerous tipping points like the Antarctic glaciers melting, we'll have to engineer our way out of the crisis.

Since we're on Q&A s, an engineer brought up a point about ice melting in a glass of water (in an attempt to shed light on glacier melt, etc).

Whether the snows of Kilimanjaro and the melting of the glaciers are 100 years (or more) ahead of the natural schedule might be moot at this point.

I would add that we have already reached or even passed the tipping point, because the melting of the Greenland glaciers is accelerating and they will not stop melting unless the atmosphere cools.

A rise in temperature to the point where the earth's ice sheets and glaciers melt is only one of many environmental tipping points needing our attention.

Many of these researchers pointed toward an expanding pool of warm bottom water undermining sea facing glaciers as the culprit for this increasingly rapid glacial melt.

When pulses of warm water are strong enough to rise over the shelf's outer ridge, that warm dense water then flows downward to the grounding point of the glacier and remains there until a new equilibrium is established via basal melting and a retreating grounding point.

However, he also supports the idea that warming has recently stopped and has argued against some well - established points of climate science, such as observed sea level rise and glacier melting.

While recent headlines about the woes of U.N. - led efforts to assemble a comprehensive picture of the science have caused gleeful headlines on The Drudge Report and other skeptical media outlets, the vast weight of the evidence — from melting glaciers to warming oceans to satellite temperature readings, and much more — still points to a changing climate caused by human activity.

According to scientists, the melting of Earth's glaciers has reached a point of no return.

But all three also point to the same bleak conclusion: human impacts on the atmosphere promise only the choice between a dangerous future, and a catastrophic one, as the planetary thermometer rises, glaciers and icecaps melt, the oceans become more acidic and more likely to flood coastal communities, hurricanes and typhoons become more intense and destructive, heatwaves become more lethal and droughts become more devastating.

One such as Rajendra Pachauri's attack on an Indian scientist for pointing out for four years that the IPCC's claim on Himalayan glaciers was incorrect during the period that the consulting firm he led, TERI, was negotiating for a large contract to study the glacial melting of Himalayan glaciers.

Meanwhile, a U.N. report predicted $ 1 trillion in annual damage from ocean acidification if carbon pollution is not curbed, and the Antarctic ice pack appears to have grown this year partly because fresh water from melting glaciers has raised the freezing point of the near - shore Southern Ocean.

Can we reach the political tipping point that will enable us to cut carbon emissions before we reach the point where the melting of the Himalayan glaciers becomes irreversible?

The added ocean heat combines with falling melting points at depth to produce rapid melt along sea fronting glacier bases.

All glacier grounding points below 300 meters have been susceptible to basal melting from upwelled CDW for millennia, and a pattern has emerged that glaciers with deeper grounding points incur greater basal melting.

Thus the topography of the coastal shelves and depth of submerged glacier grounding points determines the impact of upwelled CDW and limits extreme basal melting to a relatively few locations as illustrated by the red and orange areas in the figure below (from Depoorter 2013)..

Another point is, that the imply of heat - uptake, made by Nic and Curry underestimated thermal sea level expansion for 1995 - 2011, would it be correct, heat - uptake in cyrosphere inclusive glacier - melting have to be larger then thought.
