Science Alert: Experts Respond

Antarctic glaciers in hot water – Expert Reaction

Sarah-Jane O'Connor posted in on October 26th, 2016.

Hundreds of metres of solid ice were lost from West Antarctica’s glaciers between 2002 and 2009, according to a US-led study published today in Nature Communications. Warm ocean waters beneath ice shelves are linked to melting the ice from below, but the effect is difficult to measure. Using data collected from a NASA airborne study, […]

Antarctic ice may melt faster than expected – In the News

John Kerr posted in on February 23rd, 2016.

Antarctica’s large land-based ice sheets may be more vulnerable to increasing global temperatures than previously thought, according to new research from New Zealand, US and European scientists. Analysing drill cores of Antarctic rock, they found that Antarctica became its warmest ever 15 million years ago  when carbon dioxide levels were 500ppm – only slightly higher […]

Getting to grips with glacial erosion – Expert reaction

John Kerr posted in on October 9th, 2015.

New research from GNS science, published today in Science, shows that faster moving glaciers carve out more of the landscape then their slower-moving peers.   Researchers spent five months using satellites to track the speed of Franz Josef glacier whilst monitoring erosion by analysing sediments collected at the face of the glacier. From the gathered data […]

Unstoppable Antarctic ice sheet collapse – expert responds

Dacia Herbulock posted in on May 14th, 2014.

Major glaciers in the West Antarctic Ice Sheet are melting faster than expected, and the entire sheet is now headed for inevitable collapse, according to two research papers publicised this week. The first, from the journal Geophysical Research Letters, draws on 40 years of observations of West Antarctica’s glaciers and multiple lines of evidence to conclude that glaciers on the […]

Glaciologist responds to doubts over Himalayan melt

Peter Griffin posted in on January 19th, 2010.

The United Nations Intergovernmental Panel on Climate Change is reexamining a report it issued that suggests Himalayan glaciers could vanish by 2035. The veracity of the claim is in doubt after it was revealed that information cited in the report was based on “grey literature”. It was taken from a WWF report that was not […]

New Zealand glaciers disprove global climate sync-up

Peter Griffin posted in on May 1st, 2009.

Researchers have long puzzled over how climate has evolved over thousands of years in different regions of the world. Has the climate in the northern half of the globe changed in tandem, or in opposition to, the climate in the southern half? An international group of researchers (including New Zealand scientists) has taken up this […]
