Ikaite crystals found in Greenland and Antarctica could provide information about climate trends of the past, according to…
Despite peak global temperatures in 2005 and 2010 (unprecedented in the instrumental record), a recent sharp plunge in volume of the Arctic Sea ice and a spate of extreme weather events, coal mining, coal…
Ancient penguin DNA shows that Macquarie Island penguins have recovered genetic diversity in the past 80 years. Macquarie…
Ice caps and glaciers in Greenland and Antarctica shed 150 billion tons of ice annually from 2003 to 2010 according to the…
We are seeing the first signs of dangerous climate change in the Arctic. This is our warning that humanity is facing a dire future. The Arctic region is fast approaching a series of “tipping points” that…
Everyone is looking at Antarctica right now: attention at last! The 100th anniversary of Douglas Mawson’s landing at Commonwealth Bay in Antarctica arrived and passed without the promised celebration…
Last December’s meeting of the American Geophysical Union featured three of the world’s leading climate scientists: James Hansen (NASA’s chief climate scientist), Elco Rohling (National Oceanography Centre…
New research from Purdue and Yale Universities suggests that a drop in carbon dioxide was a driving force in the formation…
A few weeks ago, NASA announced that the area of Arctic ice is now almost as low as it was in 2007, its historic minimum. The extent of ice has reduced to 4.33 million km² compared to the mean (1979 to…
Penguins may use smell to determine if they are related to a potential mate. Despite the large size of penguin communities…
Scientists have produced their version of how Greenland’s climate might have looked over the last 800,000 years. Using drill…
Ice and frozen ground at the North and South Poles are affected by climate-change-induced warming, but the consequences of…
New research indicates that although Arctic sea ice will melt away as the climate continues to warm, it may temporarily stabilise…
When does “national interest” equal “national sovereignty”? Apparently when Australia looks south. That position seems to be emerging from think tanks and senior government officials in the stop/start…
For the first time scientists have observed the power of a tsunami to break off large icebergs in Antarctica. The tsunami…
The recently-released Lowy Institute report, Antarctica: Assessing and Protecting Australia’s National Interests is both timely and likely to stimulate much discussion about Australia’s future presence…
After a 10,000-year absence, wildfires have returned to the Arctic tundra, and new findings raise concerns the fires could…
Something does not add up. About two weeks ago, a scientist working for the US Bureau of Ocean Energy Management, Enforcement and Regulation (BOEMRE), Dr Charles Monnett, was placed on administrative leave…
The Antarctic ice sheet is less stable than previously thought, and Greenland is comparatively safer, according to research…
