Are we falling short in freshwater biodiversity understanding & research?

An astonishing 96-author call to action from conservation researchers argues that to little funding is available for this crucial ecosystem that we require as a resource to support (our) lives:

Worth sharing!

I saw this picture on Twitter here twitter.com/BrexitBin/status/1 and it is such a nice and thought-provoking picture that I cannot but share it here also.

Explanation: Europe has an ongoing refugee crisis at its Eastern border where state powers are testing their powers on the back of refugees, to cut a complex story short. Then people still try to cross the Mediterraean to reach Europe, while being pushed back to.. well.. countries with questionable stabilities and governments..

With running, the Water Science Forum (WSF) of the Royal Society of Chemistry with other stakeholders has signed a "call to action" to maintain water resources against the impact of

What is your action pledge? Send the WSF a video statement, and it may be shown at the COP26 closing section!

Next round of EU legislation that may break encrypted chats:

With the aim to prevent sharing of illegal content particularly where it affects children, the EU has passed in July a regulation permitting providers of online services to scan contents
eur-lex.europa.eu/legal-conten

According to a EU commission impact assessment, to be presented in December, this could become mandatory (picture)

... which would render encrypted service provisions impossible...

Assessing the organic chemistry of is challenging as there are so many (little defined) compounds in the water. But untargeted by LCMS helps bringing order into the chaos.

... and at times, lucky hits may strongly suggest the presence of a specific compound, that can be validated by targeted determination.

Not to forget, high incidence means replication implies mutation, and the emergence of more aggresive variants may not be a necessity but no impossibility either (chemistryworld.com/news/race-t).

The IPCC in its latest report emphasizes that with more data, model predictions have improved.
ipcc.ch/report/sixth-assessmen

This allows now to disentangle the various scales of climate effectors (attached picture).

As it emerges, carbon dioxide, mainly emitted by humans, has still the major impact.

Please look into the "Summary for Policymakers" (SPM) of the IPCC report which very well details the advanced understanding in fairly plain language

How does dissolved organic matter (DOM) change over time?

As part of the AquaDiva project at @unijena we are investigating the (DOM) in an aquifer monitoring system in Germany.

Our multi-year dataset now allows to query DOM changes in response to water flows.

This short-video (2 min) gives an insight – comments & contact welcome!

Im Nebel ruhet noch die Welt,
Noch träumen Wald und Wiesen:
Bald siehst du, wenn der Schleier fällt,
Den blauen Himmel unverstellt,
Herbstkräftig die gedämpfte Welt
In warmem Golde fließen.

And back we are under public life curbs for in , for the rest of the month. Together with most of . Measures seem tempered, so let'shope they'll suffice as a circuit breaker.

At least it's again an opportunity to spend time outside and discover new spots
