This means Portsmouth summers are getting progressively warmer and drier, with an increased chance of drought, wildfires, and heat stress, particularly to those who are more exposed, such as outdoor workers, or residents who are more vulnerable such as older people and babies, and those with underlying health conditions. The effects of heat will be felt most in dense urban areas of Portsmouth like Somerstown, Portsea, Southsea, Fratton where there is lots of hard surfaces and little vegetations such as trees to help cool the air. This is called the ‘urban heat island’ effect which means urban areas are often even hotter than surrounding areas.
Winters will be warmer and wetter, meaning an increased frequency and severity of flooding. An increased frequency of extreme weather events such as heatwaves, heavy rain, storms and extreme cold.
As a low-lying coastal city, Portsmouth is at risk from continually rising sea level.
Climate change impact to our environment
Plants and animals will also find it harder to live in our city. Some species might disappear, and new species might appear. Seasons might start earlier or later and our wildlife might struggle to adapt.
The impacts to us, our environment and society will be enormous if we do not reduce our emissions to avoid the worst of climate change.
