The impact of climate change

In the UK and around the world, the Red Cross is united to support people affected by climate change. 

Extreme weather events – like floods, storms, cyclones, heatwaves and droughts – are on the rise, changing people’s lives.. But, this isn’t something new to us. Getting people through emergencies is what the Red Cross has always done, whether they happen here at home or across the world.

Our teams have supported people impacted by climate-related disasters for decades. Chances are, you have too – with every penny given to an emergency appeal, every show of solidarity with people who fled their homes, or every retweet of our UK flooding advice.

It’s simple: together, we can do what we do best – we can help each other. You can help us reach people here at home and around the world who are being pushed into crisis by extreme weather every day. We're working in 192 countries to help communities feeling the impact of the changing climate

Stand with us. Climate unites us.
