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

The latest multi-model El Niño forecast just came out from the IRI and... wow. The ensemble mean of the dynamical models would basically make a tie for the all-time strongest El Niño based on the satellite (OIv2) and instrumental (HadISST) records.

I never quite appreciated the scale of Indonesia. Its length is about the same as Boston to London. And ~21% longer than Seattle to Miami.

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. nature.com/articles/s4385… @CIRESnews @CUBoulderATOC

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. link.springer.com/article/10.100…

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).

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
