“Are global river flows no longer natural? Can we really talk about natural rivers? [The authors] started asking ourselves these questions a few years ago over wonderful discussion sessions.
[They] argue that global river systems have entered a new phase, one of Anthropogenic River Flows, where flow regimes arise from the persistent interaction of:
• the physical alteration of river systems,
• the institutional and socio-technical organisation of water use and allocation
• broader global and systemic processes operating across scales.
In the Anthropocene, these domains do not operate independently because a change in one alters how the other two function. Global water risks and river flow properties then become an emergent property of these interactions.
As a result, [the authors] call for a rethinking of how we study, understand, and manage river flows to better reflect this new reality…”

A very cool study using #clumped #isotope measurements in #oyster shells from the Early #Cretaceous showing high and variable #seasonality in response to climate changes caused by atmospheric #CO2 shifts. #mollusk shells again demonstrated as useful climate archives!

[a paper from a few years ago, but very pertinent considering the horrific events in Los Angeles area in early 2025]
