The science of tree ring analysis is called dendrochronology. This tree was recently cut in the park near me. How old do you think it is?

Final step in the biosynthesis of iridoids elucidated

Iridoid-producing plants use a cyclase to synthesize the characteristic double-ring structure of this important class of defense compounds and medically relevant substances

Tree ring scientists Caroline Leland and Mukund Rao of LDEO's Tree Ring Lab are building a quiet but effective bridge between science and salvage—ensuring that irreplaceable wood and the rich clues to climate data and human history it holds don't go to waste. 🪵 lamont.columbia.edu/news/rings-t...

A zebra at a conference? 🦓 Yes! 😂 CREAF recently joined the Worldendro Conference in #Zambia, the global hub for dendrochronology -the #science of tree-ring analysis 🌳🔬 Let’s dive into what we shared! 👇

Tree ring science is so wild once you dive in! Hope you enjoy the read 🌲📚

So when people are being honest about @michaelemann.bsky.social 's nature trick, good faith people understand the methods being used and why.

Bad faith people look at the language and scream "Ah-HA! A trick!"
Why some tree ring records haven’t tracked recent warming
Rising air pollution reduced sunlight in places that were already cloudy.

I went to see the 2000 year old lime tree at Westonbirt and that's what I was expecting, and this is what I got.

I’m glad we rec’d our NSF–TUES grant in 2013 for TREX–Tree-Ring Expeditions. A host of Pacific NW geoscience faculty developed marvelous curricula via an NSF grant, and hundreds earth science teachers attended field trips to Pacific NW sites via NSF—latter two thru Evergreen St. College, PSU & PLU.

A study in npj Climate and Atmospheric Science, using in-situ observations and two different tree-ring reconstructions, shows that summer 2024 was the warmest summer in 2000 years in northern Fennoscandia. 🧪
Summer 2024 in northern Fennoscandia was very likely the warmest in 2000 years - npj Climate and Atmospheric Science
Summer 2024 was exceptionally warm in northern Fennoscandia, with June-August mean temperatures at several long-term weather stations surpassing the long-standing record set in 1937. In this region, summer mean temperatures have been reconstructed from tree-ring proxies, which provide annually resolved and millennium-long records of past climate. Here we show, using in-situ observations and two different tree-ring reconstructions, that summer 2024 was the warmest summer in 2000 years in northern Fennoscandia. Employing an attribution method based on Coupled Model Intercomparison Project Phase 6 climate models, we further estimate that climate change increased the likelihood of this extreme season by a factor of 93 (5–95% uncertainty range 19–881) and increased the temperature an additional 2.1 °C (1.4–2.8 °C). Atmospheric circulation patterns influencing both summers 1937 and 2024 were largely similar, suggesting a comparable large-scale circulation influence. Our findings highlight the impact of climate change for the contemporary heat extremes in Fennoscandia, indicating that the warming of summer climate is emerging from its range of natural climate variability over the last two millennia.

Toured the U Arizona Tree Ring Lab yesterday & what a delight! Dendrochronology informs many other sciences incl marine biology, astronomy, chemistry etc. Got to hold a piece of the 5,098 year old bristlecone pine from Great Basin. It was emotional esp given the threats to pure science rn. 🌳🔬💚
