3/ Our results give also insight towards interpretation of speleothem isotope records.

/2 microbial GDGTs (not used for temperature this time!), molecular markers for biomass burning, and climate modeling, allowing to disentangle the influence of mean annual precipitation and its seasonality. Orbital forcing is clear driver.

1/ Article alert! 🎺 The latest article from the PhD project of Petter Hällberg is now online! www.sciencedirect.com/science/arti... We used the distribution of long chain alkanes, their hydrogen isotopic compositions, in combination with with insights gained from...

Disentangling seasonal and annual precipitation signals in the tropics over the Holocene: Insights from δD, alkanes and GDGTs

Rainfall seasonality in the tropics has a substantial impact on both ecosystems and human livelihoods. Yet, reconstructions of past rainfall variabili…

Comes on top of a paper 1 year ago suggesting organic carbon weathering offsets silicate weathering. So we now would appear to have mountain building as a source of CO2 not a sink. Im not sure that's tenable. www.nature.com/articles/s41...

Rock organic carbon oxidation CO2 release offsets silicate weathering sink - Nature

Silicate weathering of uplifted rock depletes atmospheric CO2, but oxidation of revealed rock organic carbon supplies CO2, offsetting depletion to a degree dependent on regional geological history.

We've created a new faculty position at the Department of Earth and Planetary Sciences at @ethzurich.bsky.social and invite applications for the position of Assistant Professor (Tenure Track) of Geomitigation of Greenhouse Gases. Further information and application:

Very interesting reading on agriculture and emissions. Your diet (meat/vegetable) is much importart than eating locally. Changing to organic farming needs to be done carefully to avoid unwanted side effects. ourworldindata.org/effective-po...

How effective are policies in reducing the environmental impacts of agriculture?

All countries now have policies, but not all work as intended. Some drive trade-offs or lead to spillover impacts elsewhere, but there are many examples of successful stories.

This is a great @canarymediainc.bsky.socialwww.canarymedia.com/articles/car...

The startup made a big splash, then ran aground this summer. Its story has a lot to teach us about trying to geoengineer our way out of climate change.

Phantastic Job!

A truly impressive paper was published this week with a new reconstruction of global temperatures over the last ~500 million years. There is something tremendously satisfying about seeing a proj...
