New paper alert🚨!
The impact of flooding on food security across Africa, now out in @PNASNews
tl;dr
Floods effect food security in some countries more than others, in various ways
Floods can be positive and/or negative
Key factors: Flood type, Spatial scale, Time since event

Chances favor a “very strong” El Niño emerging this fall, but while we understand what El Niño is, every El Niño is different, with uncertainties in timing, extent, and duration of impacts, says climate scientist @wxpizza of @columbia_ncdp. Via @PopMech. popularmechanics.com/science…

"Every El Niño is different in terms of timing, magnitude, and geographic extent, and such differences lead to variability in the impacts—on temperatures and rainfall, for example—on a global scale," says @wxpizza of @columbia_ncdp. Via @ABC. abcnews.com/International/el…

Given likelihood of El Niño's rapid strengthening and extreme weather events, now is the time to ready financing, human resources, and logistics to support the most vulnerable, writes @wxpizza of Red Cross Red Crescent Climate Centre and @columbia_ncdp. climatecentre.org/17489/wmo-…

Citing 'remarkable agreement' by models, @WMO now says current #ElNiño will strengthen rapidly, increasing likelihood of #heatwaves, #droughts, heavy #rainfall & extreme-#weather worldwide; @KenyaRedCross pic, Nov. 2023 ElNiño-related flood response - bit.ly/4eO2s9G

El Niño is here. @columbiaclimate professor/@columbia_ncdp faculty director @jeffschlegel and NCDP climate scientist @wxpizza explain why that’s a head start, not just a headline. Learn more: ncdp.columbia.edu/ncdp-persp…

“A flood means we need to be close to a river—that’s how we’ve been trained to think. But you don’t need a riverbed; you don’t need a coastline,” says @columbia_ncdp's @wxpizza. All you need is rain. And that can happen almost anywhere. Via @TheAtlantic. theatlantic.com/ideas/2026/0…

🤔 You Asked: What Exactly Is a ‘Super’ El Niño? 💡 Columbia Climate School experts Muhammad Azhar Ehsan, @mfting, @wxpizza, and climate reporter Tracy Wholf explain what a strong El Niño could mean for the planet this year: news.climate.columbia.edu/20…

As El Niño forecasts have grown more accurate, humanitarian groups, governments, companies, farmers have become more adept at preparing, though the most vulnerable may not have access to all the info they need, says @wxpizza of @columbia_ncdp. Via @CNN. cnn.com/2026/05/19/climate/s…

"Cada El Niño es diferente en términos de momento, magnitud y extensión geográfica, y tales diferencias conducen a la variabilidad en los impactos —en las temperaturas y las precipitaciones, por ejemplo— a escala global", dice el experto @wxpizza de @columbia_ncdp . Vía @ABC .

Climate scientist @wxpizza of @columbia_ncdp is watching how forecasters factor AI predictions into public storm warnings. "Even if models are considered better or high quality, decision-making is not necessarily simplified," he says. Via @climate. bloom.bg/401O6dt

As part of its Moonshot Goal 8 Program, scientists address the question: Is it possible to tame river flooding? Andrew Kruczkiewicz weighs in on this debate in a French article in @LesEchos by @jhennoparis. lesechos.fr/idees-debats/sci…

Freezing rain is "by far the most dangerous" form of precipitation. When rain freezes on & around surfaces, that could mean cars are encapsulated in ice. Bridges & roadways can also accumulate & freeze over puddles, noted @wxpizza. axios.com/2026/01/23/ice-sto… @columbiaclimate @axios

Places are seeing disasters they aren’t used to, extreme events are intensifying faster, & they are becoming more complex. That requires earlier warnings & new approaches to response & recovery, noted Andrew Kruczkiewicz. @wxpizza @AP @columbiaclimate ow.ly/tKnL50XSqQv
