Climate overshoot: What happens when the world gets too hot for too long? Passing 1.5 degrees will hurt people more. It shows how climate overshoot increases risks for food, health, cities, and fragile communities.

What happens when the world gets too hot for too long? Researchers at several institutions argue that climate overshoot will reshape risks for societies long before temperatures drift back down. ow.ly/F7za50XxEUV @wxpizza.bsky.social @climate.columbia.edu

The study is on "The human and social impacts of climate overshoot" - but the world is home to millions of other species that will also be severely impacted academic.oup.com/pnasnexus/ar...

It seems increasingly likely that the world will overshoot the Paris Agreement’s aspirational goal of 1.5°C of global mean temperature rise. A Perspective calls for research on the social and humanitarian impacts of climate overshoot. In PNAS Nexus: https://ow.ly/hNhX50Xx2pq

Societies Are Unprepared for the Human Costs of Climate Overshoot While scientists have made progress describing overshoot’s physical impacts, its humanitarian and social consequences need greater focus, say the authors.

✨ Societies are unprepared for the human costs of climate overshoot. Understanding how overshoot will affect people’s lives and livelihoods—before, during, and after disasters—must be part of climate planning, policy, and finance. ow.ly/L4LI50XtxVr @climate.columbia.edu

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

The Rising Threat to New York City’s Food System An increasing risk of flooding in Hunts Point could upend a large share of the city food distribution.

“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!

Flash flood warnings are up in the US this year — Here’s where The 3,722 flash flood warnings that occurred between Jan. 1 and July 30 are a record high for the time period going back to 1986.

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.

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

Still many elements to assess & attribution/fault is premature, 1 aspect to highlight is that while flash flood is a subtype of flood, flash floods have subtypes themselves, with differences in predictability, impact, data, risk perception, etc. Some outlined here:
