Not exact matches

Enkelmann appreciates the challenge of collecting samples here because this range has the highest peaks of any coastal mountain range and is only 20 kilometers from the Pacific Ocean, but she points out that it is a tough area to study because of the big ice sheets.
For scientific purposes, the Antarctic ice sheet is often divided into catchment basins so that comparative measurements can be taken to work out how the ice in each basin is changing and discharging ice to the oceans.
«If protective ice shelves were suddenly lost in the vast areas around the Antarctic margin where reverse - sloping bedrock (where the bed on which the ice sheet sits deepens toward the continental interior, rather than toward the ocean) is more than 1,000 meters deep, exposed grounding line ice cliffs would quickly succumb to structural failure as is happening in the few places where such conditions exist today,» the researchers point out.
To visualise how he would approach the filming of the climactic battle, DGA Quarterly recounts how he laid out a blue sheet on his office floor for the ocean and with a fishing line towed two little square - rigger ship models around the room, blew wind on them from a fan, and filmed it with a lipstick camera.
Because the drains out of the various bathtubs involved in the climate — atmospheric concentrations, the heat balance of the surface and oceans, ice sheet accumulations, and thermal expansion of the oceans — are small and slow, the emissions we generate in the next few decades will lead to changes that, on any time scale we can contemplate, are irreversible.
It was said above that the ocean is warming just like the land (& air and ice sheets / glaciers), that the heat in the ocean dwarfs that in the land and air, that the warming is due to the net solar imbalance (solar in, less LW out - no mention of CO2.)
In our paper, based on data from Jason Box from the Geologic Survey of Denmark and Greenland, we estimated that the Greenland ice sheet has already come out of equilibrium since the beginning of the 20th century and has since added about 13,000 cubic kilometers of meltwater to the ocean.
I haven't had time to read all of these postings — let alone Jim Hansens DIRE piece (though I DID just download it and I will do so; and Thank You, by the way, for telling the WHOLE SCARY Truth Dr. Hansen); but, out of what I did scan, I didn't seem to notice any references having been made in regards to the possibility that the Fresh Meltwater comming off of the Greenland Ice Sheets — and them plunging striaght to the bottom of the North Atlantic Ocean — could shut down the so - called «Atlantic Conveyor».
The West Antarctic Ice Sheet (WAIS) is out of balance because it is losing significant amounts of ice to the ocean, with the losses not being offset by snowfall.
On the other hand, if by some chance and what ends up happening is totally independent of human activity, because it turns out after all that CO2 from fossil fuels is magically transparent to infrared and has no effect on ocean pH, unlike regular CO2, say, but coincidentally big pieces of the ice sheets melt and temperature goes up 7 C in the next couple of centuries and weather patterns change and large unprecedented extreme events happen with incerasing frequency, and coincidentally all the reefs and shellfish die and the ocean becomes a rancid puddle, that could be unfortunate.
This small outlet glacier south of Jakobshavn Isbrae is moving ice from the interior of the ice sheet out to the ice sheet edge (top right), where the ice calves off into the ocean.
Actually Fielding's use of that graph is quite informative of how denialist arguments are framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing over of short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing over of issues like lag time between emissions and effects on temperatures... etc..
It will take thousands of years for the ice sheet to push its nose back out into the ocean.
Josh Willis, a lead NASA scientist for the Jason missions, which measure sea level rise from space and Ocean's Melting Greenland (OMG), is a passionate communicator about human - caused global warming.Come listen to a talk on what his team has found out about the role of the oceans in ice loss around the margins of the Greenland Ice Sheet.
