when currents pushed it westward toward the Canadian archipelago.
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 She

When a glacier
melts, it thins, weakens and speeds up, letting more landlocked
ice drain into the ocean, causing
sea levels to rise.

Stora Lögdasjön was connected to the Baltic
Sea when the inland
ice melted around 10,000 years ago.
The entire cave system flooded at the end of the last
ice age,
when melting glaciers raised
sea levels.
This has resulted in temperatures an astonishing 20 °C warmer than usual, so
sea ice is
melting when it should be forming.
Ice melting occurs during the summer when temperatures rise above freezing in some places, depending on how high the ice is above sea level and how close it is to a po
Ice melting occurs during the summer

ice is above
sea level and how close it is to a pole.
When the planet's big
ice sheets collapsed at the end of the last
ice age, their
melting caused global
sea levels to rise as much as 100 meters in roughly 10,000 years, which is fast in geological time, Mann noted.
When ice sheets
melt and oceans heat up, the
sea level rises.
Before the
melt,
when they were hunting on stable
sea ice, the polar bears had a big advantage over their favoured prey.
When you're talking about global warming and
melting ice caps, as everyone seems to be, a five - millimeter adjustment in the modeled diameter of the Earth could be the difference between
sea levels appearing to rise from any given year to the next and then appearing to drop.
Paradoxically, both phenomena are likely linked:
When sea -
ice North of Scandinavia and Russia
melts, the uncovered ocean releases more warmth into the atmosphere and this can impact the atmosphere up to about 30 kilometers height in the stratosphere disturbing the polar vortex.
However, Roland tells us, the
ice shelves can retard the flow of glaciers into the
sea, and speed up glacier
melt when they disappear.
Freshwater injection already has a large impact
when ice melt is a fraction of 1 m of

When projecting how
sea levels could rise over the coming centuries, one of the most difficult factors for scientists to gauge is how much of the Earth's vast

melt, and how quickly.
Scientific knowledge input into process based models has much improved, reducing uncertainty of known science for some components of

Sea ice is critical for polar marine ecosystems in at least two important ways: (1) it provides a habitat for photosynthetic algae and nursery ground for invertebrates and fish during times
when the water column does not support phytoplankton growth; and (2) as the
ice melts, releasing organisms into the surface water [3], a shallow mixed layer forms which fosters large
ice - edge blooms important to the overall productivity of polar
seas.
John — your premise is incorrect; Arctic
sea -
ice is not a concentration of mass, and
when it
melts it doesn't redistribute around the globe (other of course than in the same way any other Arctic seawater redistributes).
