Volcanic drivers during LIA

Details

Published: Monday, 22 October 2018 11:15

The fast retreat of Alpine glaciers since the mid-19th century, documented in photographs, is used as a symbol for the human impact on global climate, yet the key driving forces remain elusive.

In a new paper from VICS working group, authors, led by Michael Sigl, argue that volcanic eruptions, and not industrial soot, were responsible for an apparently accelerated deglaciation starting in the 1850s.

Their findings, published in The Cryosphere, support a negligible role of human activity in forcing glacier recession at the end of the Little Ice Age, highlighting the role of natural drivers.

2019 EGU Awards & Medals

Details

Published: Thursday, 18 October 2018 12:11

PAGES is pleased to announce our Scientific Steering Committee (SSC) member Ed Brook will receive the Hans Oeschger Medal at the 2019 European Geosciences Union General Assembly in Vienna, Austria.

This medal was established by the Climate: Past, Present & Future Division in recognition of the scientific achievement of Hans Oeschger. It is awarded to scientists for their outstanding achievements in ice research and/or short-term climatic changes (past, present, future). See the list of previous recipients, which includes many PAGES people, here.

Plus the leader of PAGES' Climate Variability Across Scales (CVAS) working group Shaun Lovejoy will receive the Lewis Fry Richardson Medal.

This medal was established by the Nonlinear Processes in Geophysics Division in recognition of the scientific achievements of Lewis Fry Richardson. It is awarded to scientists for their exceptional contributions to nonlinear geosciences in general. See the list of previous recipients here.

Flood events in Transylvania

A new contribution to the Floods Working Group on flood events in Transylvania during the last millennium was published in The Holocene today.

Ioana and Aurel Perșoiu released the first record of past flooding activity from the Carpathian Mountains, Eastern Europe, covering the last ~1100 years, from the early Medieval Warm Period through to the end of the Little Ice Age. Their findings are based on documentary evidence and sedimentary records along Someșul Mic River, one of the main rivers draining this region.

The paper is a product of the Floods cross community workshop held in Grenoble, France, in July 2016.

New ECN blog post

Published: Wednesday, 17 October 2018 10:43

New contribution to the PAGES Early-Career Network (ECN) blog, The Early Pages:

Many studies from the Northern Hemisphere show that a sudden cooling of the climate happened 8,200 years ago - this is known as the 8.2 ka event.

Author Ignacio Jara asks himself what this event looked like in the southern half of our planet. Check out his article on ocean currents and climate, teleconnections, and what is known so far (or what isn't) about the Southern Hemisphere.

Climate instability in LIG

Details

Published: Friday, 12 October 2018 11:10

Considerable ambiguity remains over the extent and nature of millennial/centennial-scale climate instability during the Last Interglacial (LIG; 129-116,000 years ago).

In a new paper released in Nature Communications today, members of the PAGES Working Group on Quaternary Interglacials (QUIGS) find that the Last Interglacial was punctuated by a series of century-scale arid events in southern Europe and cold water-mass expansions in the North Atlantic.

The data also show that the amplitude of the Last Interglacial changes was greater than that of the Holocene. Greenland ice-melt and runoff as a result of excess high-latitude warming may have contributed to the weakening of the Atlantic meridional overturning circulation and to the observed climate changes.

Lead author Chronis Tzedakis said that "although not a strict analogue for future anthropogenically-driven changes, the profile of the Last Interglacial that emerges is one of enhanced century-scale climate instability, with implications for ice-sheet and ocean dynamics."
