New paleoclimatic reconstructions of the Pacific Northwest reinforce the hypothesis of the sea ice highway as one of the routes of arrival of the early Americans (American Geophysical Union). #paleoclimatic #archaeology https://news.agu.org/press-release/north-americas-first-people-may-have-arrived-by-sea-ice-highway/
North America’s first people may have arrived by sea ice highway

New research suggests some early Americans may have traveled on winter sea ice down the coast from Beringia as long as 24,000 years ago

#TippingPoint #research: potential "forthcoming collapse of the #AtlanticMeridionalOverturningCirculation (#AMOC)" [1]

"major concern as it is one of the most important tipping elements in #Earth’s #climate system

[...] model studies and #paleoclimatic reconstructions indicate that the strongest abrupt climate fluctuations [...] are connected to the bimodal nature of the AMOC" [1]

RealClimate: What is happening in the Atlantic Ocean to the AMOC?

RealClimate: For various reasons I'm motivated to provide an update on my current thinking regarding the slowdown and tipping point of the Atlantic Meridional Overturning Circulation (AMOC). I attended a two-day AMOC session at the IUGG Conference the week before last, there's been interesting new papers, and in the light of that I have been changing

If you work with #paleoclimate, you will be happy to see that #pastclim 1.1 is now out!

https://evolecolgroup.github.io/pastclim/

We have many new functions, now summarised in a #cheatsheet
https://evolecolgroup.github.io/pastclim/pastclim_cheatsheet.pdf

We also explain how to work with custom #paleoclimatic data
https://evolecolgroup.github.io/pastclim/articles/a2_custom_datasets.html
(but if you do, please consider making them available to others, as explained in this vignette)

Manipulate Time Series of Palaeoclimate Reconstructions

Methods to easily extract and manipulate palaeoclimate reconstructions for ecological and anthropological analyses, as described in Leonardi et al. (2023) <doi:10.1111/ecog.06481>.
