Antarctic Peninsula: nonlinear intensification of melt unprecedented in last 1000 years

Mon 15 Apr 2013

A new study analysing an Antarctic Peninsula ice core has determined that there has been a ten fold increase in melt intensity over the last 600 years. I reported recently that the Antarctic Peninsula summer melt season prolonged by global warming according to research from the British Antarctic Survey.

Antarctic Peninsula summer melt season prolonged by global warming

The melt season on the Antarctic Peninsula has been getting much longer over the last 60 years, at some locations doubling in length according to the research lead by Dr Nick Barrand of the British Antarctic Survey. Increased melting season increases the melting stress of ice shelves which hold back significant glacier discharge and sea level rise.

Greens propose boost to funding for Antarctic and Southern Ocean marine research

Hobart as an important scientific hub and gateway for Antarctic and southern ocean marine research, not only for Australia but for other national scientific expeditions. That is the vision of a new policy initiative launched by the Greens today to boost the research and logistics capacity of Australian Antarctic, climate and marine scientists based in Hobart.

Japanese whalers escalate dangerous attacks on Sea Shepherd in refueling attempt

More ship collisions have occurred in the Southern ocean with the Nisshin Maru ramming the Bob Barker up against the fuel tanker Sun Laurel while blasting the ship with water cannon to try and flood their engines and exploding concussion grenades on the decks of the Bob Barker and the Sun Laurel.

Claims human rights of tanker crew violated as Japan suspends whaling in Antarctica

Notes thrown by crew from the South Korean owned Panama registered tanker, Sun Laurel, used for refueling the Japanese whaling fleet, indicate at least some of the crew were taken to Antarctica without their consent or foreknowledge and have been denied means of communication with their families and the International Maritime Organisation about violations of their labour rights.

One of the Directors of Sea Shepherd Australia, Bob Brown conducted an interview Wednesday afternoon in which he called for the Australian Government to intercede directly with Tokyo over the Nisshin Maru ramming of 4 ships in the Southern Ocean and also called for an Australian naval presence to uphold international law in Antarctic waters. Bob Brown is a former leader of the Australian Greens and a former Tasmanian Senator.

Update 25 Feb 2013: Japanese Whalers escalate dangerous attacks on Sea Shepherd in refueling attempt

20 Feb 2013: In the Southern Ocean tempers are fraying over whaling with Sea Shepherd hindering all attempts to slaughter whales in the Southern Ocean Whale Sancturay in their Zero Tolerance campaign this year being run from the Australian Sea Shepherd Organisation. A Major confrontation erupted today north of the Australian Casey Antarctic Base when Sea Shepherd used it's vessels to prevent the Nisshin Maru Whaling Factory Ship coming alongside the Panama registered Korean fuel supply ship the Sun Laurel.

Global Warming: Attenborough warns of ice shelf destruction in Antarctica

UK Naturalist and documentary maker David Attenborough has warned about the implications of climate change melting ice sheets in the polar regions but emphasised the changes under way in Antarctica "is likely to have the most dramatic effects of all".

Global warming in Antarctica: Glaciers accelerating, west Antarctic ice sheet losing mass

Sat 05 Nov 2011

Scientists have been studying the climate change impact on ice shelfs and glaciers for some time in Antarctica, and particularly around the Antarctic Peninsula where there is substantial warming occurring increasing ice shelf melt and the speed and discharge of glaciers. The most recent studies predict a faster retreat for the Thwaites Glacier and that warm ocean currents are already speeding the melting of the Pine Island Glacier and Ice Shelf and Getz Ice Shelf. A NASA Icebridge flight detected a major new rift in the Pine Island ice shelf on October 14 - the start of the calving of a massive iceberg. A recent paper in Nature Geoscience discusses the Stability of the West Antarctic ice sheet in a warming world and the likelihood of collapse that would raise sea level by more than three metres over the course of several centuries or less.

I reported as far back as 2004 that warming in Antarctica was cause for concern with ocean food chain crashing due to Antarctic warming. More recently in April 2011 I discussed Penguin numbers suffering with krill decline due to Global Warming.
