New ice core record shows climate variability in West Antarctica

Similar warming and cooling trends occurred in the mid-nineteenth and eighteenth centuries From AGU highlights: A 308-year ice core record provides new data on climate variability in coastal West Antarctica and shows that a clear warming trend has occurred in recent decades. To study climate over the past 3 centuries, Thomas et al. analyzed stable…

Global warming and the Titanic II – on an epic collision course?

People send me stuff. This morning I got a note about a new study that says: Over the past decade, ice-loss from the Greenland Ice Sheet has been accelerating, raising concerns about runaway losses and consequent sea-level rise. But research into the four major Greenland fast-flowing glaciers has enabled scientists to show that while these…

Antarctic summer effect confined to peninsula

From the British Antarctic Survey , at least they didn’t pull a Steig and try to claim the observed effect on the Peninsula affects the entire continent. The peninsula is essentially a different Koppen climate class than the main continent, and is at the whim of changes in ocean currents and the SAM,  plus Sea…

Antarctic peninsula was 1.3°C warmer than today 11,000 years ago

From the British Antarctic Survey New climate history adds to understanding of recent Antarctic Peninsula warming Results published this week by a team of polar scientists from Britain, Australia and France adds a new dimension to our understanding of Antarctic Peninsula climate change and the likely causes of the break-up of its ice shelves. The…

New ice loss unit – the New Jersey

From the University of Texas at Austin, an ice shelf as big as New Jersey might collapse, if conditions are right. Tipping points and all that. I suspect this gives notice to the press that we are switching from Manhattans to New Jerseys to measure ice loss in news releases and subsequent news stories. Then…
