There is a need for improving forecasts of both rapid intensification & its subsequent impacts. New data could strengthen modeling for both the meteorological variables – wind, precipitation, storm surge, social, & humanitarian impacts, noted @wxpizza.bsky.social. ow.ly/znfp50WPSCu

“What about these compound effects that we see quite a lot?”, noted @wxpizza.bsky.social, a flood specialist at the @climate.columbia.edu. “There needs to be systems in place for different types of floods, & also for situations where those floods can combine & co-occur.” ow.ly/fHa750WGA6j

Engrossing meeting of the minds at the workshop this week. Nine creative yet plausible storylines were developed and a whole range of new cxns made. Thanks again to all who attended, and especially those who made it happen. We're excited to see what this format & these ideas can catalyze!

Warming atmosphere combined with factors like socioeconomic conditions, land use, and land cover increase the risk of flash floods, which will continue to grow and evolve in the coming years, says @ncdp.bsky.social climate scientist @wxpizza.bsky.social. Via @wvtm13.bsky.social.

It has been more than a year since #HurricaneBeryl passed. Beryl joined the ranks of destructive storms that intensified very rapidly & posed a challenge to preparedness, even with the best forecasts science can provide, noted @wxpizza.bsky.social. ow.ly/s8vQ50Wy9xE @climate.columbia.edu

In this Q&A, @ncdp.bsky.social climate scientist @wxpizza.bsky.social talks about why Texas floods were so devastating, how warning systems need to consider different populations, and how we might integrate technology + local knowledge to avoid such tragedy: news.climate.columbia.edu/2025/07/15/a...

We are saddened & devastated by the impacts of the catastrophic flooding in Texas. ow.ly/x9I250WmrsV #texasstorms

Many discussions with @wxpizza.bsky.social and others about this last mile imperative and flood warnings. And lots of resonance, sadly, with Western North Carolina, here with Dave McConville revkin.substack.com/p/how-appala...

The world’s most vulnerable people increasingly face threats related to climate change. Many lack the ability to move away from impacts like heat, flooding and landslides. Experts say governments and organizations can invest in low-cost interventions aimed at reducing suffering.

Thank you, @mongabay.bsky.social for featuring our @natcomms.nature.com paper on involuntary immobility. Open access paper: www.nature.com/articles/s41...

“It has been raining a lot in New York, which hasn’t seen a September this wet in over a century. Climate change is very likely stoking more ominous and lengthy downpours because as the atmosphere heats up, it can hold more moisture, said Andrew J. Kruczkiewicz, a senior researcher… at Columbia”

In many cases, involuntarily immobile populations fall within that most vulnerable category. We don’t have the appropriate level of detail in terms of data to fully understand them in a way that respects who they are & their differences, noted @wxpizza.bsky.social. news.mongabay.com/2025/04/glob...

Excited to host the first #RiskKAN symposium at @iiasa.ac.at with presentations and a panel on #multi-hazard risks in a changing world on april 28th. This kicks-off the new #Risk-KAN WG-structure co-chaired by @marleenderuiter.bsky.social, S.Singh and myself. iiasa.ac.at/events/apr-2...

The translations of weather warnings are important for more than extreme weather events, said Andrew Kruczkiewicz. apnews.com/article/weat... @columbiaclimate.bsky.social @wxpizza.bsky.social

#ClimateChange impacts “can force people to stay in place” resulting in involuntary immobility due to various obstacles, e.g., political & social. As @lisathalheimer.bsky.social et al. note, a lack of data & knowledge inhibits policy & planning to address this growing problem doi.org/10.1038/s414...

How can policymakers help people who can't flee climate risks? New study by CIESIN's @fabiencottier.bsky.social & Alex de Sherbinin, @ncdp.bsky.social's @wxpizza.bsky.social, @lamontearth.bsky.social's @monahemmati.bsky.social & Radley Horton, & colleagues explores policy and preparedness solutions.

Additional data and a more detailed representation of involuntary immobility within policy and practice lead to more impactful preparedness, anticipatory action, and more effective early response to disasters and extreme weather events. @wxpizza.bsky.social

"...the understanding of these dynamics is in its infancy... The current suite of risk assessment tools and methods falls short of what is needed for society to understand and react to compound events."

You need low relative humidity, drier than average conditions or dry conditions, and wind. These are primary meteorological factors that lead to wildfire risk...not necessarily ignition but spread, says @ncdp.bsky.social climate scientist @wxpizza.bsky.social. Via SMH. www.smh.com.au/world/north-...
