#PDSI
May 2026 had the second-worst May drought conditions in contiguous U.S. history, with a Palmer Drought Severity Index (PDSI) of -6.93. The only worse May: the Dust Bowl year of 1934 (a PDSI of -7.03). Three of the top-10 months for worst U.S. drought since 1895 have been in 2026:

Worst April drought in contiguous U.S. history: Palmer Drought Severity Index (PDSI) was the lowest on record for any April, at -7.56. The only worse drought conditions: March 2026 (PDSI of -7.85), and during the Dust Bowl months of July-August 1934 (PDSI of -8.09 and -8.42, respectively).

Drought a huge concern this summer. Palmer drought severity index (PDSI) by state for March 2026 had 6 states with their worst drought on record, with 22 others experiencing a top-10 worst drought. Only Michigan had an above-average lack of drought. From: www.ncei.noaa.gov/access/monit...

Exciting new work from Taylor et al in J of Clim. showing tree-ring PDSI reconstructions can identify compound drought-heatwave events in regions with strong land-atmosphere coupling. Clever disentangling of temp and ppt in PDSI recons!

"Climatic conditions that caused the Great Drought and Global Famine arose from natural variability, and their recurrence, with hydrological impacts intensified by global warming, could again potentially undermine global food security." 🧪🌊

🚨 Drought ALERT in France 🇫🇷! 🚨

🎯 Over 50 years (1973-2023), extreme droughts have surged.

💥 #PDSI tells the story: PDSI> -3 = 💔🌡️ "Severe" is the new norm

⏳ Time to ACT before it's too late! 🌎🌿

marte, tomei a liberdade de olhar no PDSI e vc levou suspensão por 2 posts muito antigos, como tem acontecido com a gente. recomendo mandar por email pra moderação e questionar. nós temos feito isso com frequência, mas sem resposta

Le grandi conquiste sociali degli anni 70 sono state ottenute collettivamente, per lo piu grazie al PC, il PSI, PDSI,... poi i primi attivisti performativi vollero metterci il cappello, facendoli diventare successi individuali,non di milioni di volontari. Da allora non si é piu ottenuto un granché.

The Palmer Drought Severity Index (PDSI) shows shows dryness in shades of brown across much of the US, and some wetter areas in northern reaches of the US.

What is PDSI?

Well, thank you @bjnnowak.bsky.social for introducing this amazing graph style to us! 🎨✨

😍 I couldn't resist applying it to my recent work on PDSI classification for #Thailand, and I must say — the results are striking! 🟡🔵

Truly a blend of art and science!....

The US drought monitoring program is a long-term, very robust set of data and analyses. The Palmer Drought Severity Index (PDSI) is a good long-term tool for plant growth. The current PDSI is not consistent with your assertions. There is plenty of other data at drought.unl.edu that you can explore.

The kiddos, honorary tree-ringers Dimitris and Jordan, and I made some great progress on our drought tree cookie today! We made it from 1895-1927CE. Only 98 more years to go! #STEAM #DendroArtsnCrafts #PDSI @hydroclimp.bsky.social @utkgeography.bsky.social

Not all vets voted for Trump, and those that did got fooled.

Vets are some of the most vulnerable people in America.
Many suffer from PDSI.
