To help contextualize the newly released #IPCC Report, here's 800,000 years of Earth's CO2 history in 30 seconds.

New paper led by @CUBoulder PhD student Max Elling shows that tropical oceans drive year-to-year malaria variability in Malawi. Soil moisture is the key link and a foundation for early warning systems.

New study led by @CIRESnews/@CUBoulder's Max Elling proposes a practical framework to help identify how model choices create performance tradeoffs that affect metrics directly relevant to nature and society.

It's been a very warm and dry winter in Boulder, CO. Data from @NOAANCEI GHCN-Daily since 1900.

🚨🌏 Hot off the press in @NatureClimate
Our study, led by Yanbin Xu, shows that El Niño (ENSO) doesn’t just affect weather — it can quietly shape human health and economic outcomes over many years.

@CUBoulderATOC Thank you, but that paper was led by Sloan Coats (@drynamics). The description matches this paper better (and Sloan as a coauthor of that!).

We ran 15 experiments using models from four institutions (MPI, @NASA / GISS, @NCAR_Science and @NOAA / GFDL).

Key Points

Let's talk about Luis Rojas, the @Yankees third base coach. How do you make this send? Yes Bellinger is fast, and no Duran's arm is not the strongest in the league, but a throw from shallow left and 90+ feet to go? This was decision opened up the game. Please help, @Jomboy_

[American Meteorological Society @ametsoc]

The "U.S. Climate Collection" is now open for proposals! A joint initiative of AMS and @theAGU, the Collection will help sustain the momentum of U.S. climate assessment research.

Learn more and submit your proposal: https://t.co/yaparJCnUx

[AGU (American Geophysical Union) @theAGU]

📢 Submissions are now open for the U.S. Climate Collection, a joint @theAGU + @ametsoc initiative.

This special collection will publish U.S.-focused climate assessment science that’s free to read, ensuring rigorous, accessible science informs decisions for years to come.

"my mentee sent an email thanking me for my support and guidance, which she said helped increase her confidence. She probably doesn’t know that she helped increase my confidence, too."

Big El Niños 🌊 usually have big 🌎 teleconnections.
The one in 2023/24 didn’t. Why?
Rainfall anomalies in the tropical Pacific were suppressed due to greater warming in Indian and Atlantic Oceans.

A new observational benchmark for equatorial upwelling
@USCLIVAR Research Highlight

Our general tendency to underestimate equatorial upwelling may offer a clue into the disagreement between historical trends and climate model simulations of Pacific SSTs.

185 departures in a day. Up about 50% from this time in 2021. (Nothing to do with the holiday weekend. Last Thursday was just an average day in terms of traffic.)

Every day, Jeffco's airport exports their lead and noise pollution all over @bouldercounty including @townofsuperior, @CityLouisvlleCo & @Lafayette_CO. This was a single day last week.

The vast majority are loud, slow-moving, fixed-wing propeller planes flying a few hundred feet above dense residential neighborhoods, parks and schools before returning to RMMA so they can do it again.
