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

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

🚨🌏 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. doi.org/10.1038/s41558… #ENSO #ClimateImpacts

@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!). agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

Led by Kris Karnauskas (@OceansClimateCU), the team shows how wind changes shape regional ocean heat content and sea level, with a clear example of Ekman and Sverdrup control. journals.ametsoc.org/view/journals/…

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_

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: bit.ly/46JuY71

📢 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. 🔗 lite.spr.ly/6004zF8K

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. nature.com/articles/s4324… Led by Lei Zhang, with @mat_collins @CIRESnews

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. usclivar.org/research-highl…

Deadline extended by one week... applications due June 22! @theAGU @AGU_Eos

Sea level and climate variability in the Pacific Ocean Work led by former @CIRESnews Visiting Fellow Chris Little uncovered 3 distinct spatial patterns in Pacific Ocean tide gauge sea level records... cires.colorado.edu/spotlights/sea…

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.)

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.

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.
