Nearly all of the text of this article on an interesting ice core proxy series (James Ross Island) from the Antarctic Peninsula was written in June 2014, but not finished at the time for reasons that I don’t recall. This proxy was one of 16 proxy series in the Kaufman 12K pdf. 60-90S reconstruction. I […]
Rising global temperatures and warming ocean waters are causing one of the world’s coldest places to melt. While we know that human activity is causing climate change and driving rapid changes in Antarctica, the potential impacts that a warmer world would have on this region remain uncertain. Our new research might be able to provide some insight into what effect a warmer world would have in Antarctica, by looking at what happened more than 129,000 years ago.
A common opinion (e,g, Scott Adams) is that the “other proxies”, not just Mann’s stripbark bristlecone tree rings, establish Hockey Stick. In today’s post, I’ll look at PAGES2K Antarctic data – a very important example since Antarctic isotope data (Vostok) is used in the classic diagram used by Al Gore (and many others) to illustrate […]
Stenni et al (2017), Antarctic climate variability on regional and continental scales over the last 2000 years, was published pdf this week by Climate of the Past. It includes (multiple variations) of a new Antarctic temperature reconstruction, in which 112 d18O and dD isotope series are combined into regional and continental reconstructions.
An Anarctic bay encompassing 600,000 square miles of the Southern Ocean will gain protection from fishing for 35 years. The area is said to be the earth’s most pristine marine ecosystem. [1]
Attendies at the United Nations (UN) meeting in Hobart, Australia, agreed unanimously to designate the Ross Sea a Marine Protected Area (MPA) after 5 years of negotiation brokered by the U.N.’s Commission for the Conservation of Antarctic Marine Living Resources.
Like many others, I was interested in the recent controversy arising from findings of Zwally et al 2015 that there had been ice mass gain gain of ~112±61 Gt/year over 1992-2001 and ~82±25 Gt/year over 2003-2008.
A favorite exam question in my first-year climate class was, “Why is the North Pole warmer than the South Pole?” I changed it each year, to confuse students who looked at last year’s exam; “Why is the South Pole colder than the North Pole?” Most people have no idea about the geography of the Poles […]
