Okay, anyone have separate shapefiles for the Upper and Lower Colorado River basins? Seems impossible to find online.

We’ve got a new dataset that’s hi-res and research ready: MESACLIP. Researchers used two supercomputers to create the MESACLIP dataset which features the Earth system in unprecedented detail, including snow cover and sea surface temperatures. Learn more: https://bit.ly/4rBK9bg

Given the latest NOAA CBRFC inflow forecast for Lake Powell, I dusted off this plot from my Twitter days and updated it. The Feb 1st outlook for Colorado River flows hasn't been this poor in >35 years. Even if wetter weather ahead, bottom-10 outcome likely. h/t @glenwoodrek.bsky.social

You use data from ESA instead of NASA because you have more confidence in it. I use data from ESA instead of NASA because NASA has the worst data sharing infrastruture on the planet. We are not the same.

Your regular reminder that when folks say "its cold outside where I live, what happened to global warming?" that the world is big, and weather still exists.

Huge congratulations to my friend Piers Forster on being appointed a CBE. We got our PhDs in Meteorology at the University of Reading in the 1990s and have since worked together on many things including IPCC and the Climate Change Committee. He's a truly inspirational scientist and communicator ☺️

This was a fun story to write, stick around to the end for a speed run through the past 500 million years of climate history

Anyone have experience with/knowledge about the maps from this company? e.g.: themaparchive.com/product/the-... Interested in their paleomaps, but difficulty to to figure out what baseline data they are using.

NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.

I love this also because of the complete lack of self awareness that, if using AI for this was so much MORE work, then why not just do it the normal way?

If you’d like to hear Ben Santer talking about this “arc of history” from the IPCC’s discernible influence finding 30 years ago to the present, then his talk at CRU’s 50th anniversary is a nice intro to climate fingerprinting youtu.be/ZinW-m2GDvU?...
