Climate crisis to destroy 167 million homes in next 20 years

9th June 2021

Supported by Professor Andrew Collins at Northumbria University, a new data forecast from disaster relief charity, ShelterBox, shows that if extreme weather events continue to increase at current rates, we face losing 8.35 million homes a year between now and 2040.

That’s 167 million homes – the equivalent of all our homes in the UK wiped out six times or all of the homes in the US.

During the three days of the G7 summit in Cornwall, an estimated 69,000 homes could be lost to extreme weather, the equivalent of 1 in 4 of families in Cornwall being forced to flee.

The devastating loss of homes is a major impact of the climate crisis but the charity found people still think of animals and the natural world first. A ShelterBox-commissioned poll found that less than 10% of people in the UK visualise humans when they think of the effects of the climate crisis, with nearly half (43%) thinking of polar bears.

ShelterBox is calling for world leaders to do more to help communities around the world who are losing their homes to extreme weather events, such as storms and floods, which are becoming more powerful and destructive due to our changing climate.

With the UK government hosting both the G7 summit and COP26 in November, Cornwall-based international disaster relief charity, ShelterBox, is urging world leaders to accelerate global solutions to global issues and recognise the devastating impact our changing climate is having on vulnerable communities, right now.

The climate crisis is creating an unprecedented need for emergency shelter around the world as it intensifies extreme weather and worsens already complex conflict situations.

ShelterBox is calling on the Prime Minister to show robust leadership and encourage world leaders to do more to support families displaced by disasters including floods, cyclones, hurricanes and drought.

There has been an 83% increase in climate-related disasters across the last 20 years. These disasters have ripped up homes, destroyed food supplies and displaced millions of people.

The data forecast uses the latest IDMC GRID displacement figures, which show 30 million people were displaced due to climate related extreme weather events in 2020.

ShelterBox worked with Professor Andrew Collins, Professor of Disaster and Development at Northumbria University, to forecast what this increase could mean for homes lost in the next 20 years.

If we continue to see climate related extreme-weather events increase at the same rate, the world faces losing nearly 167 million homes by 2040 – that’s the equivalent to all of the homes in the UK wiped out six times, or all of the homes in the US wiped off the planet.

Sanj Srikanthan, ShelterBox Chief Executive, says: “When we think of climate change and habitat loss, we tend to think of the natural world first – polar bears on melting ice caps, or forests in flames. Those things are important, but we must recognise that increasingly extreme weather is having a devasting impact on people too. It is causing irreversible damage, robbing families of homes, livelihoods and loved ones.

"ShelterBox provides essential shelter aid to help people rebuild their lives and repair their homes. Last year we supported families with almost 28,000 emergency shelters. Each of these homes is a starting point for them to rebuild and recover, but the need is still overwhelming. The number of displaced people is growing at a startling rate every year, and there is an unprecedented need for emergency shelter around the world.”

The direction of current travel is clear for all to see and drastic actions need to be taken now, using the G7 and COP26 negotiations to achieve the change we need.

“With displacement directly experienced from extreme weather events already increasing, the situation is further exacerbated by the cascading effects of climate change on regional instability and open conflict. The data cited here should be taken extremely seriously, now rather than any later.”


1) Commit to providing emergency shelter to communities all over the world facing devastating new disasters caused by our heating world.

2) Support longer-term projects to help countries afford disaster-resilient housing and sustainable livelihoods, as changing weather affects agriculture-dependent communities.

3) Ensure vaccines are not only affordable and available to all countries, but also support the logistics needed to get vaccines to every corner of the globe.

Broadcaster and naturalist Steve Backshall, a supporter of the charity, says: “Climate change is having a devastating impact on our earth, destroying resources and habitats across our natural world. With the climate crisis having such a profound impact on our environment and animals, it’s easy to forget the impact that its having on people too.

"Across the world, people are being forced to flee unsafe, storm-damaged housing, or witnessing entire streets being washed away from them by flash floods. We all know the importance of having a place to call your own, and this is a right currently not being afforded to so many as a direct result of the climate crisis.

"As a proud advocate for our environment and the protection of animals, I am delighted to be supporting ShelterBox in this next step in protecting our world, but this time, I’m fighting for the humans too.”
