Using the CESM2 Large Ensemble, we find that some of the drivers of elevated atmospheric river activity between the Last Interglacial and future are the same. We can expect to see more summertime storms impacting the Greenland ice sheet in the future, likewise driving extreme melt...

The preference for summertime storms drives enhanced melt over the ice sheet when the Arctic is warmer. This simulation featured a dynamic Greenland ice sheet, which allowed us to show that storms drive extreme melt at low elevations but ice accumulation up high...

When the Arctic is the warmest, atmospheric rivers that impact Greenland tend to form in the North Atlantic and Pacific, while later they form southward. Notably, the orbital configuration brings more summer storms to the ice sheet early on...

This drives a poleward shift in atmospheric rivers which is driven in part by thermodynamic changes (moisture) across the Arctic and dynamic changes (winds) across the mid-to-high latitudes. Storms shift southward late in the Last Interglacial when orbit is similar to today...

Warmer high latitudes lead to increased moisture over the Arctic, a poleward shift of the prevailing winds, and a weakened Arctic cyclone. All of which are important for moisture transport towards the Arctic...

Holding onto this one piece of good news. Maybe there is hope for the Democratic Party after all

The answer to all of our problems🧪⚒️❄️🥼

Puppy’s first snow!❄️

I think the Elderfield proxy timeline curve applies pretty well to many peoples opinions about the platform post election/AGU.

Super fun poster session, thanks to everyone who stopped by! ❄️🧪⚒️ #agu24

…and while you’re at it, come see my bestie’s poster next door. Austin has a really interesting dust record from the Last Interglacial from Allan Hills that suggests some pretty significant changes around Antarctica. Come chat with us! #AGU24

For those of you that are attending #AGU24, come see my poster on Friday! Let’s talk about Antarctic Ice Sheet stability, water isotopes, and ice-ocean-atmosphere interactions.

Smoke from the fire in the Palisades blanketing NYC and northern NJ. The first picture is today and the second is a clear day from the same spot. Bad day for those of us with asthma!

Go Husky’s!

Do you like atmospheric rivers? Greenland? The Last Interglacial? Come see my poster tomorrow at #AGU23

If you’re at #AGU23 come hear me talk about past ice sheet stability and dust using climate models tomorrow at 2!

Some pretty views on the morning dog walk!
