Climate overshoot has huge implications for where we live, how we get our food, & our quality of life, yet despite these potentially cataclysmic shifts, there has been little work done on the human implications of this world, noted @wxpizza.bsky.social. ow.ly/5i6e50XQ4gV @climate.columbia.edu

2025 was a historic year - making headlines for disastrous wildfires, catastrophic floods in TX, and deadly heatwaves in Europe and Asia. Read the top stories that shaped the State of Our Planet. @climate.columbia.edu @wxpizza.bsky.social news.climate.columbia.edu/2025/12/22/y...

It is becoming increasingly irresponsible to focus solely on the physical modeling elements of overshooting [2.7°F/1.5 °C of warming]. We need to start thinking about what the [human] scenarios look like for a post-1.5 °C world. @wxpizza.bsky.social. ow.ly/I3G850XNaTY @climate.columbia.edu @vox.com

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

... with the cost of doing nothing potentially creating tensions with the humanitarian principle of ‘do no harm', noted @wxpizza.bsky.social.

✨ 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

“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

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.

“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...

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...

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
