Scientists, including from British Antarctic Survey, have used #octopus #DNA to discover that the West #Antarctic Ice Sheet (WAIS) likely collapsed during the Last #Interglacial period around 120,000 years ago – when the global temperatures were similar to today.

"With each flip from a glacial to an #interglacial #climate there have been sudden, sharp rises in atmospheric #methane, likely from expanding tropical #wetlands.

These great climate flips that ended each #IceAge are known as #terminations.

Full terminations take several thousands of years to complete."

Rising methane could be a sign that Earth's climate is part way through a 'termination-level transition'

Since 2006, the amount of heat-trapping methane in…

🌊 🌊 New Paper Out! 🌊 🌊

Led by Chris Brierley, our manuscript on Indian Ocean variability across the latest edition of various paleoclimate modeling intercomparison projects (#PMIP) is out in Climate of the Past (#CotP): cp.copernicus.org/articles/19/

We look at the consistency (& lack thereof) of simulated temperature responses & impacts on interannual hydroclimate changes over the Indian Ocean rim for the #midHolocene, #LGM, last #interglacial, and an abrupt 4 x CO₂ simulation. #Paleoclimate #Climate #IndianOcean #ClimateSimulations #ClimateOfThePast #ClimateChange

Early Last #Interglacial ocean warming drove substantial ice mass loss from #Antarctica

The future response of the #Antarctic ice sheet to rising temperatures remains highly uncertain. A useful period for assessing the sensitivity of Antarctica to warming is the Last Interglacial (#LIG) (129 to 116 ky), which experienced warmer polar temperatures and higher global mean sea level (GMSL) (+6 to 9 m) relative to present day.

Location and age profile of the Patriot Hills BIA. (A) Location of Antarctic ice and marine records discussed in this study and austral spring–summer (October to March) SST trends (over the period 1981 to 2010; HadISST data). (B) Trace gas (circles), tephra (triangles), and boundary (square) age solutions for surface ice along transect B–B′ relative to an arbitrary datum along the transect (displayed in D). The dashed lines denote unconformities D0–D2 at their surface expression. (C) Basal topography of the Ellsworth Subglacial Highlands (West Antarctica) with the locations of airborne radio-echo sounding transect A–A′ (displayed in E) and Rutford Ice Stream (IS) (29). The Horseshoe Valley, Independence, and Ellsworth troughs are given by the initials HV, IT, and ET, respectively. (D) The location of Patriot Hills in Horseshoe Valley (LIMA background image) with the BIA climate line (marked by transect B–B′), dominant ice flow direction, and distance to grounding line. (E) Airborne radio-echo sounding cross-section of ice within Horseshoe Valley, Independence, and Ellsworth troughs (modified from ref. 29). Digitization highlights basal topography (brown), lower basal ice unit (gray), and upper basal ice unit (red) as well as internal stratigraphic features (black for observed, dashed for inferred, and purple for best estimate).
