And one more - ever wanted to know what the weather was like during the PETM? then this project with @climategordon.bsky.social is one for you! www.findaphd.com/phds/project...
Are extreme rainfall events more frequent in a warmer world? at University of Southampton on FindAPhD.com

I’m surprised people are surprised. Isn’t it a well known fact that aviation fuel is not taxed bc of international agreements. One of the many hidden subsidies to fossil fuels.

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.

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.

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.

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.

A long time ago I could vote online (Dutch parliament) but that was later changed back to snail-mail voting..
