Standing by your poster like a salesperson is bad enough. But being in competition for attention with a poster buddy is antithetical to collaborative science. Big thumbs down.

Interesting. I never knew this about the sequential naming system. Thanks.

Love this. Thank you! I was just explaining ELI to an insurance company and didn't have anything to point to.

Nice analysis. It shows that shear (aka El Nino) is dominating this year.

Great point about data uncertainty going back in time. I would still like to explore physically what's behind the more recent back-to-back years of late first hurricane in your list. Would also be cool to do this for landfalling events too - if not too noisy.

James Done @climate-done.bsky.social · 04/09/2026
Is it just me, or are there too many back-to-back years in your list than by random chance? We know La Nina can pulse across 2 or even 3 years, but the hurricane-supressing El Nino not so much. Curious.

I found my photo from Aug 16, 2008. It actually looks very similar to your July 2023 photo. The past 3 years have not been kind to it.

Wow, what a difference in just a few years. I'll have to dig out my old photo. I think I was there on July 4th (not sure why I thought finding parking on that day at the eponymous trailhead was a good idea). If I find it, I'll post it here. Will be interesting to compare.

Great photo, but the glacier looks in bad shape. Last time I was up there (probably 12 years ago), that small basin was filled with blue-white ice.

Kinda surprised El Niño had such an abrupt arrival (assuming the spike is not noise). Thanks also for the nice shear climatology - I've not seen that before.

True. Maybe also stories have the ability to adapt to cultural change in a way that static obs can't. We're exploring the role of scientific storytelling at an upcoming CESM workshop: www.cesm.ucar.edu/events/works.... It should be a cool session.

I have the @metoffice.gov.uk poster about these D-Day forecasts on my office wall. An icon of usable science! Also not really an 'untold story'.

Thanks for the shout-out! Another take on this is that with hurricanes becoming stronger, on average, the building code benefits will only increase in time.

If scientific metrics & risk communications describing environmental hazards don’t resonate with people’s lived experiences, they’re less likely to be useful in helping inform & safeguard communities, write @climate-done.bsky.social & colleagues from @ncar-ucar.bsky.social eos.org/opinions/env...

Humans acutely experience climate change when they encounter extreme environmental conditions, but scientific definitions of “extreme” often don’t reflect communities’ complex lived experiences.

I loved the ENSO blog for it's accessible writing style and graphics/analyses I couldn't find elsewhere. I regularly quoted the blog and shared its graphics to aid my science communications across the insurance industry (pertaining to hurricane risk).

Thanks for the additional plot. Interesting how the distance between the mean and max curves (and therefore the daily variance) is greatest during the flash flood season. It's hot and dry until it's not.

James Done @climate-done.bsky.social · 29/07/2025
Yes, I think you can see a hint of that in the daily max (green) curve in Russ's plot.

James Done @climate-done.bsky.social · 28/07/2025
Very cool. Thanks. I agree it's remarkable how sharp the seasonal flood report peak is. It's much more peaked than the precipitable water curve. I wonder why would that be? Maybe the column flow is only slack enough for a shorter period than the PW is moist enough.

That Bavarian paper is one of my favorites (thanks to @manuelaibrunner.bsky.social and @weatherwest.bsky.social). I was just presenting a slide on it (again) today. This new work a very nice study. More evidence that we need to look beyond individual rainfall event magnitudes to understand flood.

Thanks Kelly! It was a fun one to work on. You make a good point that population increase kinda undoes the good work of the building code. I did a follow-up study to find that wind speed dominates loss, but wind duration and wind directional change can be impt: ascelibrary.org/doi/10.1061/...
