The rate at which ice is disappearing across the planet is speeding up, according to new research.
[...] The figures have been published today (Monday, 25 January) by a research team which is the first to carry out a survey of global ice loss using satellite data.
The team, led by the University of Leeds, found that the rate of ice loss from the Earth has increased markedly within the past three decades, from 0.8 trillion tons per year in the 1990s to 1.3 trillion tons per year by 2017.
Ice melt across the globe raises sea levels, increases the risk of flooding to coastal communities, and threatens to wipe out natural habitats which wildlife depend on.
[...] Lead author Dr. Thomas Slater, a Research Fellow at Leeds' Centre for Polar Observation and Modelling , said: "Although every region we studied lost ice, losses from the Antarctic and Greenland ice sheets have accelerated the most.
[...] The increase in ice loss has been triggered by warming of the atmosphere and oceans, which have warmed by 0.26°C and 0.12°C per decade since the 1980, respectively. The majority of all ice loss was driven by atmospheric melting (68 %), with the remaining losses (32%) being driven by oceanic melting.
[...] Just over half (58 %) of the ice loss was from the northern hemisphere, and the remainder (42 %) was from the southern hemisphere.

If you think Canada will become habitable before 10,000y have passed, you're delusional. Above the arctic circle there's not enough soil, for starters, to farm.

No, not long at all. Look at a satellite map of Lake of the Woods, Canada. Same landforms north of the border as south, but south of the border there's lots of agriculture. With warmer weather and hardy settlers Canada could well accommodate many more people. After all, let's recall that about 10,000 years ago ice sheets covered everything down to about Nebraska. It did not take that long for humans to set up shop after the ice sheet retreated.
