‼️EXTRAORDINARY EVENT
MOST EXTREME HEAT WAVE IN WORLD CLIMATIC HISTORY GOING ON

Hundreds of records smashed with extreme margins allover Middle East

Wait for a long streak of post
We are seeing something unprecedented in history
Every single country is breaking records

🌊❄️🧪 🇦🇶 Please share:

We have learned that the National Science Foundation is moving ahead with plans to decommission the U.S. Research Vessel/Ice Breaker Nathaniel B. Palmer this October.

If you care about Antarctic research, please read on (1/n)

Maybe this will become amplified by increasing use of AI? I really hope the structure of the review system is reconsidered, for example publisher houses paying/hiring reviewers

Bioregions | One Earth If nature were to draw a map of the world what would it look like? One Earth presents a novel biogeographical framework defined by 185 unique bioregions.

Really happy, today, to learn that this website exists: www.oneearth.org/bioregions/

Years of drought turn forest into source of CO₂ - Press release on our research with @simonhaber.bsky.social and @chriswernerlab.bsky.social at @icos-ri.eu site DE-Har, showing tree mortality following droughts has fundamentally shifted forest structure & functioning uni-freiburg.de/en/years-of-...

Preprint with @lucascernusak.bsky.social, @florianabusch.bsky.social and Graham Farquhar!

We show that mesophyll cell water status is the key signal regulating non-stomatal control of transpiration. We introduce a mechanistic model linking plant hydraulics and gas exchange.

Opposing seasonal trends in source water and sugar dampen intra‐annual variability in tree rings oxygen isotopes Variations of oxygen isotopes δ18O in tree rings provide critical insights into past climate and tree physiological processes, yet the mechanisms shaping the intra-annual δ18O signals remain incompl...

Take a look at our new paper! Opposing seasonal trends in source water and sugar dampen intra‐annual variability in tree rings oxygen isotopes - Szejner - New Phytologist - Wiley Online Library nph.onlinelibrary.wiley.com/doi/10.1111/...

Loss of Stomatal Regulation Sensitivity to CO2 and Reduced Xylem Hydraulic Conductivity Contribute to Long‐Term Tree Decline and Mortality Increasing drought threatens forests, but tree species respond differently. We examined how long-term drought and rising CO2 affect three Mediterranean tree species with different drought tolerances....

The ability of some trees species to respond to climate and/or CO2 may increase their survival under global change. Species with lower plasticity may face higher mortality. Our new study in @globalchangebio.bsky.social onlinelibrary.wiley.com/doi/10.1111/... #WhatKillsTrees

Coming back from the field in Gabon where we are measuring trees to know how much carbon is stored in the Congo basin forests #CongoFor1.5 project

Our forest eddy covariance flux station DE-Lue was born today! Thanks to everyone who shared tips (I had never set up a 30 m flux tower before), our enthusiastic stakeholders who pushed the project forward, and my fantastic (dream) team that made this possible! Can't wait to share more soon 😊

Tracing Oxygen and Hydrogen Isotope Signals From Water Sources to Tree‐Ring Compounds Stable oxygen (δ18O) and hydrogen (δ2H) isotope compositions of tree-ring compounds preserve information about environmental waters; however, our understanding of their isotopic relationships is hamp....

Tree-ring cellulose δ18O preserves water source information more effectively than δ2H. The seasonal origin of tree water sources was estimated using transfer functions that link tree rings to water sources. onlinelibrary.wiley.com/doi/10.1111/...

Impressive time-lapse of leaf emergence during the last weeks recorded by phenocams at our research forest @uni-freiburg.de. In the @dfg.de funded @ecosense-sfb-1537.bsky.social we study forest ecosystem functioning, and species interactions with novel sensor technologies uni-freiburg.de/ecosense/

I love watching annuals grow, how their first leaves can emerge so strongly from such small seeds, and then the seedlings transform so quickly that it is like magic to the eyes

Parts of Alaska are losing 10+ meters of coastline yearly, and this loss may accelerate over the next century.

Really beautiful video!

An index, and can access NOAA download platforms for data from individual sites from it. Have noticed that when the ITRDB landing page is down, the webpages for individual site data can still be accessed via this index. Not as helpful as downloading all data, but I figured it is useful nonetheless ☺️

So impressive that you prepared this, important indeed! Have noticed the same 503 error before, has since been resolved, but is worrying… At least, the site-specific NOAA data can still be accessed via data.gov when the site is down

Nice, thanks! ☺️

There is already a package called FedData that works fine for this with ITRDB, but does your code work for isotope data?

Nice to be an extra pair of hands in Yuwen’s exciting greenhouse experiment
