Description

Climate change has already affected the physical and mental health of people in the United Kingdom. The country's climate is becoming warmer, with drier summers and wetter winters. Health threats due to climate change in the UK include heatwavesfloodsstormsair pollution and new infectious diseases, among others.

Extreme heat waves have contributed to thousands of deaths per summer, especially in cities. Without climate change mitigation or adaptation, heat-related deaths could increase sixfold by the 2050s, particularly affecting children, the elderly and people with pre-existing conditions. Heat events also strain healthcare systems, leading to surges in emergency visits and exposing gaps in infrastructure.

Flooding in the UK presents another major threat, currently affecting over six million people, with this number expected to rise significantly as temperatures increase. Beyond physical risks, floods have severe long-lasting mental health consequences, including post-traumatic stress disorder (PTSD). Climate change also facilitates the spread of diseases like Lyme disease and leptospirosis through warming temperatures and habitat changes that bring humans into closer contact with disease-carrying organisms.

Climate change is also affecting indoor and outdoor air quality in the UK such as contributing to longer allergy seasons in the UK and by contributing to mould growth and an increase in pollens and other pollutants, affecting respiratory and cardiovascular health. Additionally, climate disruptions to food systems reduce crop yields, increase reliance on imports, and raise food costs, disproportionately affecting low-income households and contributing to poor diets, obesity, and related illnesses. Mental health is also heavily impacted, with extreme weather and climate change anxiety driving distress, particularly among younger populations.

The UK is working toward net-zero emissions by 2050, focusing on decarbonizing energy, transport, and housing. The National Health Service (NHS) is implementing resilience measures to address climate-related health challenges, while nature-based solutions like urban greening mitigate impacts. However, health inequalities, particularly in low-income communities, exacerbate vulnerability to climate risks. Addressing these disparities is crucial to ensuring equitable health outcomes as the country confronts the growing impacts of climate change.
