- Reposted by Sadie J. Ryan (she/her)While there *is* evidence of both "wetter wets" & "drier dries" in warming climate, temperatures are going almost universally in one direction: Up. We're just not seeing "colder colds." Some interesting potential Arctic-related caveats still remain TBD, but that doesn't change big picture.
- Is climate change responsible for increasingly frequent or severe cold events? The evidence suggests it is not. Instead, the impact of climate change is warmer winters and less severe cold events. @hausfath.bsky.social has a great post on The Climate Brink talking about this.

- Reposted by Sadie J. Ryan (she/her)The 2025 @aaup.org Faculty in the South Survey showed 25% of respondents had actually applied for a job in another state. Now a Chronicle survey says half of faculty nationwide have at least considered it. Deep morale issues. www.chronicle.com/article/what...
- Reposted by Sadie J. Ryan (she/her)Put another way, we could get rid of corn ethanol, switch 30% of the freed-up farmland to solar to generate 100% of US electricity, and use the other 70% of the freed-up land for whatever we want.
- Reposted by Sadie J. Ryan (she/her)One of the most surprising things I've learned from my research is that "how hot it's gotten so far" doesn't tell us much about "how hot it's going to get eventually". Long-ago, really weird climates can tell us a lot more about where we're headed.
- Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/... And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10.... Paleoclimate evidence generally provides the strongest constraint on high ECS.

- In a new preprint, we combine modeling with school-level vaccine data to contextualize the risk of 'breakthrough infections' and impacts on the ongoing US measles outbreak. #idsky #episky www.medrxiv.org/content/10.6...

- New @carbonbrief.org post about the 10NICS - communicating climate science of all kinds is hard, and this is a great thing explainer for our 10 insights. Thanks @krisebi.bsky.social and Prof Fuss! Really pleased for my dengue map contribution to be in a CB post, and communicated so nicely

- Reposted by Sadie J. Ryan (she/her)Bluesky has actually been remarkably successful as an app within a relatively short time frame. Expecting it to have the same metrics as some of the biggest apps in the world is stupid.

- We are growing frozen veg. It's colder here than I've ever experienced - but I won't make claims about patterns or outliers since it's not my place to do it. Delightfully un-normal frost in the garden. The hawks are out and about and the day is progressing.

- Reposted by Sadie J. Ryan (she/her)Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.
- Still unclear on my feelings about taking 6-7 hours to take two very short flights north (NC) then south (LA) to get somewhere I could drive to on sketchy highways in 15 hours, and cannot take a train or bus to. (Probably could string buses together and get there in 2.5 days)

- I attended a lovely invited @wikipedia.org page editing meeting today. It's been a while since I did one, and relearning how it works was great. Apologies for topic vagueness, but just giving a shout out to such a highly used resource in health. Yes, really.

- Great to see this one out - one of the original questions on this #NSF BII journey - are wildlife more or less 'zoonotic' as they become more endangered? Read on below... Congrats to Kayla and the OG team!
- NEW! 🦠🦧 We revisited a perplexing paradox: do wildlife really pose less of a risk to human health as they become more endangered? Turns out, it's sampling bias all the way down: conservation risks correlate with disease surveillance blindspots. 🔓 esajournals.onlinelibrary.wiley.com/doi/full/10....

- While this is a bit of a harsh way to put it, it is not a false scare. The importance of resource allocation to health, to health infrastructure, to basic staffing, is misunderstood by the people with the resources. I appreciate the efforts to retain core services.
