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 … Continue reading

Study: warming of Antarctic peninsula due to ocean and atmospheric circulation patterns

From the University of Washington, something we covered earlier in WUWT from the BAS, but UW is now just getting around to press releases. The Antarctic peninsula is essentially a different Koppen climate class than the main continent, and is … Continue reading

Recent climate, glacier changes in Antarctica at the ‘upper bound’ of normal

From the University of Washington some walkback? In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea … Continue reading

Evidence for a Global Medieval Warm Period

From CO2Science: Medieval Warm Period (Antarctica) — Summary Was there a Medieval Warm Period somewhere in the world in addition to the area surrounding the North Atlantic Ocean, where its occurrence is uncontested? This question is of utmost importance to … Continue reading

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, … Continue reading

New study: Ocean-driven warming along the western Antarctic Peninsula needs to be considered as part of a natural centennial timescale cycle of climate variability

From Cardiff University: Tiny fossils hold answers to big questions on climate change Research explores 12,000 year fossil record The western Antarctic Peninsula is one of the fastest warming regions on the planet, and the fastest warming part of the … Continue reading

How GISS creates long term Antarctic warming

From Tallblokes Talkshop, note what happens before 1958. HOW GISS MANUFACTURES WARMING (LOTS OF IT) IN THE ANTARCTIC by Roger Andrews The close match between GISS and me after 1955 is encouraging in that it shows that there’s at least … Continue reading

RC’s Dr. Eric Steig boreholes himself on Antarctica

This is something that needs wider circulation, hence its appearance here. I’ve been mulling over how to best present this, and decided there’s nothing I could do in the way of excerpts that still told the story effectively, so I … Continue reading

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 … Continue reading

Dear Woods Hole and NCAR, maybe you missed this trend in Antarctic sea ice?

More modeling madness projecting the future, but the actual data for the past 30 years says otherwise, with a positive trend. Regular commenter Julienne Stroeve of NSIDC is one of the co-authors, so perhaps she’ll weigh in here. The article … Continue reading

NASA: Warm Ocean Currents Cause Majority of Ice Loss from Antarctica

Breaking news from NASA and the ICEsat team, that’s their headline, not mine. This really makes all the hype over the now discredited Steig et al. paper, which attempted to establish an air temperature warming trend as one of the … Continue reading

More evidence the Medieval Warm Period was global

UPDATE: 3/30/12 Since a number of commenters that are getting bent out of shape over the issue can’t apparently be bothered to read the paper, and since the authors at Syracuse themselves are under pressure because the alarmosphere has gone … Continue reading

Really? – Energy requirements make Antarctic fur seal pups vulnerable to climate change

From the University of Chicago Press Journals, a bizarre claim that less than 1C of warming globally in the last century, and essentially no change at all in Antarctica, will somehow change the weather in Antarctica and make it harder … Continue reading

New paper: A high-resolution surface mass balance map of Antarctica shows “no significant trend in the 1979–2010 ice sheet”

Uh, oh. Another talking point bites the dust. Leif Svalgaard writes in to tell me of a significant new paper. While Gore, Hansen, Branson, and a gaggle of hangers on just finished a publicity stunt tour of Antarctica to tell … Continue reading

Steig on Antarctic warming: “Rossby wave trains”

From the University of Washington, comes this upcoming paper by corresponding author Dr. Eric Steig (and co-authors)that the mechanism for warming of the Antarctic Peninsula is mostly weather pattern driven. The mechanism cited? “Rossby Wave Train” aka the circumpolar vortex … Continue reading
