Officials say Russia and China were key stumbling blocks, worried about compliance issues and fishing rights

SYDNEY, Australia (Oct. 29, 2017) — Hopes for a vast new marine sanctuary in pristine East Antarctica were dashed Saturday, October 28, after a key conservation summit failed to reach agreement, with advocates urging “greater vision and ambition”.

Sea levels to rise 1.3m unless coal power ends by 2050, report says

the extra contribution to sea level rise from antarctica will not kick in if warming is kept at less than 1.9c above preindustrial levels

University of Melbourne paper combines latest understanding on Antarctica and current emissions projection scenarios

October 27, 2017 — Coastal cities around the world could be devastated by 1.3m of sea level rise this century unless coal-generated electricity is virtually eliminated by 2050, according to a Continue reading Sea levels to rise 1.3m unless coal power ends by 2050, report says

Antarctic sea ice levels hit record low, but experts are not sure why

Unpredictable nature of Antarctic sea ice levels the focus at conference of meteorology experts in Australia this week

September 26, 2017 — Sea ice levels in Antarctica dropped to a record low this year, but experts say there is not a clear link to climate change. Continue reading Antarctic sea ice levels hit record low, but experts are not sure why

Shipping companies are under pressure to phase out use of heavy fuels, as world’s first hybrid battery-powered cruise ship set for launch in 2018

July 11, 2017 — Shipping companies are under pressure to phase out use of heavy fuels ahead of a potential ban on their use in the Arctic in the coming years. Continue reading Shipping companies urged to stop using dirty fuels in the Arctic

The Larsen C ice shelf collapse hammers home the reality of climate change

Collapsing ice shelves will further accelerate global sea level rise

June 12, 2017 — Very soon, a large portion of an ice shelf in Antarctica will break off and collapse into the ocean. The name of the ice shelf is Larsen C; it is a major extension from of the West Continue reading The Larsen C ice shelf collapse hammers home the reality of climate change

Antarctica’s high elevation is slowing rate of warming, says study

Temperatures in the Arctic are increasing around three times as fast as the global average, yet the pace of warming has been much slower at Earth’s other pole

May 18, 2017 — A new study, just published in Earth System Dynamics, suggests the difference might – in part – be down to the great heights of Antarctica’s land surface. Continue reading Antarctica’s high elevation is slowing rate of warming, says study

Climate change is turning Antarctica green, say researchers

In the past 50 years the quantity and rate of plant growth has shot up, says study, suggesting further warming could lead to rapid ecosystem changes

May 18, 2017 — Antarctica may conjure up an image of a pristine white landscape, but researchers say climate change is turning the continent green. Continue reading Climate change is turning Antarctica green, say researchers

Mapping Antarctica’s extremes is essential for understanding weather patterns, and teasing out natural climate variability from human-induced climate change, the WMO said in a statement

PARIS, France — The UN’s World Meteorological Organization published the highest temperatures on record in 3 Antarctic zones Wednesday, March 1, setting a benchmark for studying how climate change is affecting this crucial region. Continue reading UN reports Antarctica’s highest temperatures on record

The Oceans Melting Greenland project is taking important measurements to determine how fast sea levels will rise

February 26, 2017 — If you meet a group of climate scientists, and ask them how much sea levels will rise by say the year 2100, you will get a wide range of answers. But, those with most expertise in sea Continue reading OMG measurements of Greenland give us a glimpse of future sea rise

Sea levels could rise by six to nine metres over time, new study warns

Evidence that continental ice sheets are sensitive to slight increases in ocean temperature suggests ocean levels will continue to rise for centuries

January 20, 2017 — Sea surface temperatures today are strikingly similar to those during the last interglacial period, when sea levels were six to nine metres above their present height, according to research. Continue reading Sea levels could rise by six to nine metres over time, new study warns
