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…

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 the ongoing global warming debate, for if the Medieval Warm Period is found to have…

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…

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 Southern Hemisphere. Scientists have debated the causes of this warming, particularly in light of recent…

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 one corner of the Earth where GISS hasn’t seriously mutilated the raw data. But GISS…

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 decided to present it in full. I’m pretty sure Jeff won’t mind. Readers may recall…

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…
