Does El Niño offer a sneak preview of future climate for tropical forests? Well, yes. Our new study shows that heat & drought during 23-24 El Niño will likely be new normal for many tropical forests. A worrisome preview. #tropicalforests #elnino 🍁🌐 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

This is a photo of some rocks and sand. It was taken earlier today, with a camera 247,000,000 km away. It was taken on Mars. And now you're looking at it on your screen.
Dusty, red rocks, and red soil. Darker soil in the middle of the image marks where one of the rocks has been displaced.

Why VSWIR satellites struggle to see drought stress in trees: it's structure, not just water Allen et al. nph.onlinelibrary.wiley.com/share/AG5ZAK...
As leaves dry, equivalent water thickness (EWTcanopy) (as simulated at the canopy level by PROSAIL) decreases; however, the magnitude of these changes in EWTcanopy is modified or offset by changes in leaf angle distribution (termed structural drydown) that are expected to occur simultaneously, and this effect varies in magnitude and direction depending on leaf area index.

Today marks 250 years since a small group of newspaper editors, farmers, and soldiers signed a document declaring our nation's independence — a truth that feels self-evident now but was revolutionary then.
What a privilege us Americans have, to live in a nation that every one of its inhabitants can shape. What an honor us New Yorkers have, to look out over our city's waters from the shores where so many Americans bravely entered their country for the first time.
Today and all days, let us remember that patriotism is not pretending our nation is without flaws. Patriotism is every act of righteous dissent — because loving our country means fighting for the best version of it.
Happy Fourth of July, New York City.
