A major new compilation of pre-historic temperature records shows that global warming is reaching levels not seen for at least 6000 years.
Over the past 150 years, global warming has more than undone the global cooling that occurred over the past six millennia, according to a major study, "Holocene global mean surface temperature, a multi-method reconstruction approach", published in Nature Research’s Scientific Data today.
The study, led by PAGES Scientific Steering Committee member Darrell Kaufman, reconstructs global temperature over the Holocene. The global database on which the temperature reconstruction is based was compiled by an international group of paleoclimate scientists who came together in June 2019 in Switzerland for a PAGES-endorsed meeting. The methods used in the study build on those developed by several PAGES working groups.
Following the last major ice age, the Earth as a whole was warmest during the centuries around 6500 years ago. The global average temperature during this period was likely about 0.7°C higher than during the 1800s. Global warming since then has reached about 1°C.

Floods Working Group (FWG) has released a Global and Planetary Change special issue as an outcome of their PAGES' 5th Open Science Meeting session in 2017.
Edited by Lothar Schulte, Daniel Schillereff, Juan Santisteban and Fabienne Marret-Davies, "Pluridisciplinary analysis and multi-archive reconstruction of paleofloods" contains 18 peer-reviewed papers covering various regions, including New Zealand, South America, Central Asia, Europe, and the UK.
"The study of past floods, from historical and natural archives, is challenging but offers unparalleled opportunities to document the frequency and magnitude of past floods, including rare, very large events, that occurred under a broad range of climate and/or environmental scenarios," said Professor Schulte.

In May 2021, the group will hold the session "Towards an improved understanding of past flood variability and examples on how such data can have a bearing on present and future flood risk management" at PAGES' 6th Open Science Meeting in Agadir, Morocco. Abstract submission opens this Wednesday, 1 July 2020.
PAGES is pleased to announce that abstract submission and registration is now open for the 6th Open Science Meeting (OSM) and 4th Young Scientists Meeting (YSM) in Agadir, Morocco, in May 2021.
