Great shot!!

The word “unprecedented” gets thrown around a lot these days to describe the ongoing heatwave across the Western U.S., and let’s be honest — it’s absolutely justified. Perhaps the most impressive multi-day event since the 2021 PNW heat dome.

Starting my academic reading this year with a fascinating study documenting the frequency of tropical cyclones in the South China Sea over the past ~650 years. We need more of this type of data to understand extreme weather patterns and their relationship with climate.

Not particularly at the moment, I suppose 😓 Back in the good ol' days (~2019) there was a v strong potential proposal to drill the Miocene offshore the Western Ghats, Malabar Coast, which I think would've been right up both of our alleys? One can still hope (+ make our luck as you say)

A bird of prey—a Northern Harrier—in flight; with wings extended, sharp, hooked beak, and yellow eyes. The bird is brown and white (mottled) overall, has a sharp white eyebrow, and a white rump—with a sleek, aerodynamic body.

Here's a majestic Northern Harrier in flight, spotted in Avra Valley (southern AZ) 🪶

Fun fact: apparently Northern Harriers are moving their range into NE Russia for the first time in recorded history over the past few years (link.springer.com/article/10.1...)

Jay was on my PhD committee and taught me carbonate geochemistry, and to approach my speleothem problems with patience and depth. I’m deeply grateful for the time I got to learn from him. His influence will always remain a part of my journey. Will miss you, Jay!

A sad piece of news: I am heartbroken to learn that Jay Quade passed away today—a profound loss for our geoscience community. Jay was an inspirational scientist, an exemplary colleague, and an extraordinary human being.

I’ll miss you, Jay! 😞
