BalancedWx Special: My Mississippi memories of Katrina Remembering a historic event 20 years ago today

While much of the Katrina coverage rightly focuses on enduring social vulnerability, this perspective by an NWS MIC speaks to the strengths and weakness of forecasts and warnings, how far the entreprise has come, and needs our support.

Hydroclimate volatility on a warming Earth - Nature Reviews Earth & Environment Rapid transitions between extreme wet and extreme dry conditions β€” β€˜hydroclimate whiplash’ β€” have marked environmental and societal impacts. This Review outlines observed and projected changes in hydr...

Important work: Swain et al www.nature.com/articles/s43... Whiplash plus disrupted seasonal patterns socio-enviro sys are adapted to. Probably 1000's of small scale cases emerging & palpable now. CO ranchers told us gap b/w snow and summer convective P had grown affecting forage & grazing strategy.

Right, Maritime Climates hard to imagine from middle of the continent. But your lakes freeze nicely!
Here's skiing across Long Lake below the Niwot Ridge LTER.

15 miles!? Wow. Where's all the snow?
Colorado Front Range finally good XC above 9Kft. Windiest skiing after Mt Washington and Wyo's Snowy Range, love the drifts.

Yes, bottom-up, safe pathways, and decision-scaling methods seem right for climate risk management, but harder to figure how those add up to a prefered global GHG limit. The small island states went there at Paris, arguing that 2degrees was intolerable risk, pushing the 1.5 target.

Strategic Issues Facing Transportation, Volume 2: Climate Change, Extreme Weather Events, and the Highway System: Practitioner's Guide and Research Report Read online, download a free PDF, or order a copy in print.

Very useful volume for us non-engineers too! About the same time I found this helpful, including spreadsheets for students to try out.

Right. More sophisticated DM'ers know not to trust single number and can ingest quantified uncertainty into decisions (eg culvert size). Climate services challenge is to discern audience, give plausible range but not throw out model skill that can improve some choices (including by some engineersπŸ™‚).

Agree. We simulated culvert replacement strategies w/ varying rates of increasing rainfall intensity. Anticipatory enlargement under uncertainty can be inefficient, more resilient design makes sense. link.springer.com/article/10.1...
