The study shows that even though the DL model ingests paleodata assimilation products and has no information on the location of paleoclimate proxies, it is implicitly constrained by them. 2/n

Since anthropogenic global warming is an unprecedented event, we can't use paleodata to quantify tipping probability. IPCC global climate models don't tip in 21st century projections. Probabilities estimated using simpler models that don't consider all feedbacks (+ve & -ve) are not very meaningful.

We're still far away from Pleistocene small-scaled precipitation dynamics across Sahara due to topography. We proposed strong orographic effects for the Eastern D./Egypt e.g. doi.org/10.1016/j.qu... but can't quantify so far.

Although ours was on modelling and process understanding not on gathering more paleodata (which is of course also extremely important and needed).

Paleodata, but yes, the backwards timeline completely melted my brain. It didn’t help that the ‘present’ was something like 1950. I like to think we’ve moved on a bit.

Jason McLachlan: We need mechanistic models of paleodata to predict future ecosystems. Ie, pollen data tells us what trees grew in the past, mechanistic models can help translate that to biomass or other things we care about. #ESA2018

While on vacation, our latest paper, led by @cecileremy.bsky.social, was published! Cecile did a fantastic and important job bringing together a group of paleoecologists and modellers to advocate for combining paleodata with forest models to better understand cascading disturbances. Congrats!
New paper out in @ecography.bsky.social ! We highlight how combining paleoecology and modeling can help us better understand cascading disturbances in forests, e.g., drought can trigger insect outbreaks that alter fire behavior.

Paleodata (humans, veg, climate) is often interpreted qualitatively. I'd love to see more quantitave tests of synchroneity, change points.
