New review on "Unsaturation in the air spaces of leaves and its implications" in @PlantCellEnvir. In Cernusak et al., we review the evidence that refutes the assumption of universal, near saturation of air spaces in leaves. doi.org/10.1111/pce.15…

Watch #AncientForestSociety researchers in #SequoiaNationalPark make the first-ever climb🌲🧗‍♂️  of the #GeneralShermanTree (the world's largest tree) to check for bark beetles! 🐞✨ Incredible footage! Here's why: i.mtr.cool/wbdsqvwuyr 📹@NationalParkService #GiantSequoia

“Twenty-two hundred years old and counting.” Beautiful column by ⁦@LATstevelopez⁩ on scientists climbing General Sherman, the world’s largest tree, to make sure wildfires and bark beetles aren’t killing it — and thank goodness the prognosis is good: latimes.com/california/sto…

SEQUOIA NATIONAL PARK — “Roughly around the time of the Han Dynasty and just prior to the beginning of the Roman Empire, a tree began growing at an elevation of roughly 7,000 feet in what became known as the southern Sierra Nevada.” ⁦@LATstevelopez⁩ latimes.com/california/sto…

Probably the first climb ever of the General Sherman Tree, the world's largest tree. Researchers with the @AFSociety ascended the 275-foot giant sequoia this week to look for bark beetles, the latest threat to sequoia trees: sfchronicle.com/climate/articl… Video from @NatlParkService

Just wow. Last night in Yosemite #CAwx

I don't know how it is possible that Biden doesn't understand all that is at stake here, but, based on his consistent eagerness to expand fossil fuels, I am convinced he does not. He must declare climate emergency. Now. My latest piece: theguardian.com/commentisfree/…

@HappyGeoJill thanks!

A note from the stomata project: supporters will receive a postcard or a set of postcards with drawings and photographs as a thank-you. There's just over one week left to pitch in! experiment.com/california-red… #redwoods #science @lets_experiment @AFSociety

And so it begins #freshpow

In 2022 cars, factories & power plants burned more fossil fuels than in any other year in human history. In the midst of an accelerating climate emergency — fossil fuel use is *increasing*. There are no words to describe how dangerous this trend is. We must demand rapid change.

Please spread the word and help support this great project that will explore vertical gradients in tall redwood tree leaf morphology and function.

#Tahoe received 2-4 feet of snow in the last storm system, bringing the season total to about 200% above normal for this time of year.

Break in the storm today. Gulls feasting on kokanee salmon at the mouth of Taylor Creek #Tahoe

More snow in #Tahoe. And it looks like more on the way soon. A nice start to the winter. Let's hope we get some more big storms throughout the whole season.

Some pics from a recent trip collecting giant sequoia cones to preserve their genetic heritage and assist with reforestation efforts in high-severity burn areas. #conehunters #Sequoia #kingscanyonnationalpark #CAfire

snow!
