Severe storms, heat waves and wildfires can shut down the social life of a community, , and .

They’re also evidence of how climate change isn’t just changing the environments we all live in, but also impeding our ability to connect with one another.

Around the world, social connection is increasingly recognized as . It keeps our . During emergencies, social ties can also save lives. Relationships are conduits for timely . When temperatures soar, friends and neighbors share heat warnings, who may need help, and coordinate community cooling shelters when formal systems are overwhelmed.

Yet, the effects of climate change may be .

As extreme weather becomes more common and disruptive, the effects can impair relationships, interrupt routines and communication, and damage gathering places and the foundations of community traditions.

As an , I study converging social and environmental crises, including social disconnection and extreme weather. I’ve found that one of climate change’s most overlooked impacts may be its ability to worsen the .

Studies show the amount of time Americans spent interacting with friends and family in person was shut down a lot of social interaction starting in 2020. My team’s has found several ways that extreme weather is further hindering social activities.

Extreme weather keeps people apart

Extreme heat has . When outdoor temperatures become dangerous, to stay in air conditioning or near electric fans. This can come with a social cost.

“I don’t remember it being this hot growing up,” one 28-year-old social worker told my research team. “People don’t want to leave their house if it’s that hot. People don’t want to go to community events and be out in the community.”

Dr. Khristina Meissner, right, and nurse practitioner Jen Felter check on residents in Swannanoa, N.C., after Hurricane Helene’s flooding in October 2024. While the residents’ apartments might have survived the storm, flooding made reaching medical care and many other resources, friends and family much harder.

Severe storms and flooding can , preventing people from leaving their homes, reaching family or attending social gatherings. These disruptions can erode the everyday interactions that help people feel connected.

Power outages sever communication

Extreme weather can also cut off the communication channels that help people stay connected. Severe storms, flooding, winter weather and extreme heat are all associated with power outages, which can .

Electricity failures are often coupled with internet and cellular service interruptions, hindering communication via text messaging, phone calls, social media and email at precisely the time it’s needed most.

As one 74-year-old rural resident explained to my team: “We’re so isolated. We do not have any cellphone service other than through Wi-Fi. So when the power’s out, we have no cellphone service … without your phone, you really lose all your connections.”

The loss of shared places and traditions

Another way climate change can weaken social connection is by that hold cultural and community significance.

I witnessed this firsthand when of Cherry Valley, New York, in 2011. After floodwaters broke the dike, a treasured community place known as “the reservoir” – a small lake where families swam and picnicked – was emptied, leaving our rural community without one of its few gathering spaces.

Extreme weather can flood parks and dry up lakes, such as Lake Hope in Vinton County, Ohio. This image was captured by a resident who often visited the lake with her two small children. Like many others, the water levels in Lake Hope dropped significantly during Ohio’s record drought in 2024.

In my team’s Appalachian study, residents described how an extreme drought paired with prolonged heat affected places where people gather, share traditions and maintain .

Water levels in lakes and rivers dropped too low for recreation, wildfires swept through the Wayne National Forest, and crop losses meant fewer of the region’s beloved pawpaw fruit when the annual arrived.

A 68-year-old resident told us: “I look around and it’s just absolutely horrible. Our streams have gone dry. I had a friend drop off some pawpaws the other night and pitiful … nothing like what normally drops. It’s really bad and I suspect this is going to continue. We’ve got to figure something out.”

This kind of degradation of cherished places and traditions can threaten shared experiences that help communities stay connected.

These disaster often overlap

These fractures of social connection often overlap as . A severe storm, for instance, may trigger flooding and power outages during a heat wave, disrupting transportation and communication during dangerously hot temperatures.

Over time, frequent and consecutive weather hazards can weaken relationships by limiting mobility and social engagement.

A heat wave, with temperatures over 100 degrees, shut down the Washington Monument and temporarily closed the American State Fair on the National Mall on July 3, 2026, over public health concerns.

People who are already socially isolated, including older adults and those living in rural areas or lacking reliable transportation and internet access, are . Climate change and extreme weather can .

Keeping social connection amid disasters

As global temperatures rise, driven in large part by the burning of fossil fuels, . Social connection is crucial, both for responding to extreme weather and for working together to help the entire community adapt to a changing climate.

The Athens County library in Coolville, Ohio, is aptly named – it can serve as a cooling center during heat waves. Fiona Doherty,

One is for cities and counties to invest in community hubs, such as public libraries, or create new gathering spaces .

These spaces can bolster social connection year-round by hosting inclusive while also serving as , providing resources to help residents prepare for disasters, , and an internet connection.

In an era of accelerating climate disruption, social connection may be a community’s greatest asset, and yet one of its most fragile resources to protect.
