Limiting global warming to 1.5°C could halve the amount of Antarctic land ice lost by the end of the century, but maintaining current emissions – projected to raise global temperatures by 3°C by 2100 – will accelerate ice sheet loss and sea level rise past a point-of-no-return by 2060, according to two papers published today in
Nature.
The Paris Agreement is an international accord among 197 nations to limit global warming this century to 2°C, while a more ambitious target of 1.5°C is seen as the preferred – but perhaps less realistic – result.
Experts modelled the effects of melting ice on sea levels at the century s end
The Paris goal could reduce losses from glaciers by 50% and Greenland by 70%
Findings from Antarctica were unclear, however, due to current uncertainties
Meeting the ambitious target would lower sea rise from 9.8 inches to 5.1 inches
Another study warned current emissions could lead us to cross a tipping point
After this, it might become impossible to halt sea level rise for centuries to come
New research from a large international community of scientists predicts that sea level rise from the melting of ice could be halved this century if we.
Starting May 4, 2022 and continuing through July 2022,
Seabourn Venture’s Arctic summer season will begin halfway between Norway’s North Cape and the North Pole as the ship will embark guests for eight 11-day Arctic Svalbard summer cruises between Tromso and Longyearbyen; those cruises include a return flight to Oslo.
Following those voyages and continuing through September 2022, the ship will operate five 11- to 15-day voyages in the region, visit Svalbard, the North Cape and other locations in Norway, as well as take guests to Iceland, Greenland, and the Canadian Arctic Archipelago in Nunavut.
Highlights will include Scoresby Sound, Greenland; Sermilik Fjord in Greenland, which is known for its icebergs; Svalbard; and Pond Inlet, Nunavut, the eastern entry to the Northwest Passage. The voyages can also be combined for an in-depth experience up to 29 days in length.
