High resolution ~12,000 years sedimentary DNA from Lake Sulsseewli shows that alpine plant diversity is associated with human land use and climate change.
Here, the authors use sedimentary DNA, pollen, fungal spores, chironomids, and microcharcoal from an alpine lake core to reconstruct vegetation across 12,000 years. They find that vegetation responded to climate in the early Holocene, followed by a shift to human activity from 6000 years onward corresponding with an increase in deforestation and agropastoralism.
While some commentators here were busy trying to tell us it’s just normal winter weather which only appears extreme due to ‚shifting baselines‘ given global warming, there is this. ⬇️
Ocean carbon uptake could be affected by changes in circulation. This modelling study shows that meridional overturning circulation slowdown increases deep-ocean storage via the biological pump but decreases carbon uptake via the solubility pump, with a net reduction in oceanic uptake of CO2.

neither of those are pronouns!
but, thanks for making it clear that there is now no difference between truth social and twitter.
that does it for me! this is DEFINITELY my last tweet.
