How Does Global Warming Affect Our Health – The Earth is warming, rainfall patterns are changing and sea levels are rising, increasing the risk of heatwaves, floods, droughts, wildfires and other natural hazards.
These changes represent one of the greatest health security threats we face, potentially impacting the air we breathe, the quality and availability of our food and water, the risk of infectious diseases, and our mental health and well-being more broadly.

How Does Global Warming Affect Our Health
Although climate change is often considered a global problem, no country or community is immune to its effects.
Positives And Negatives Of Global Warming
In the UK, high summer temperatures are already taking their toll on health. In the summer of 2020, we observed 2,556 deaths from all causes (including deaths from Covid-19) in heatwaves and it is estimated that the number of heat-related deaths will potentially triple by 2050 if action is not taken to reduce them .
Warmer temperatures are also one of the factors that could lead to invasive mosquitoes and human-borne diseases in parts of the UK.
Climate change may also affect the quality of our air. Changes in weather may increase episodes of ground-level ozone or other particulate matter, which may increase hospital admissions for asthma or other respiratory or cardiovascular diseases.
Disruptions to food production around the world, especially in the Global South, may also pose a threat to food security, including in the UK.
Greenhouse Effect 101
While many of these impacts will affect everyone, they will disproportionately affect the most disadvantaged, further widening health inequalities.
It is clear that increasingly rapid action is needed to understand and reduce the risks that climate change poses to our health and care systems, and science has an important role to play in this global effort.
Our scientists study the health impacts of climate change, provide early warning and response to extreme weather events, quantify the health impacts of air pollution, and monitor risks arising from changes in the spread of disease or vector-induced disruptions to the food system.
Working in multidisciplinary teams, we also have experts in areas such as global health, emergency preparedness, resilience and response, data and analytics, behavioral sciences and health disparities.
Our Planet, Our Health
Much of our work is carried out in collaboration with others, from local authorities to national governments and academia, including collaborations between the NIHR Environmental Change and Health Research Unit, UKHSA and the London School of Hygiene and Tropical Medicine, University College London. . London and the Bureau met.
We engage in a range of international work, for example through our contribution to the Intergovernmental Panel on Climate Change’s Sixth Assessment Report, which provides evidence to decision-makers around the world.
We have also recently led global scientific collaboration to review definitions and classifications and to add to the hazard information profile of the United Nations Office for Disaster Risk Reduction.
This important scientific contribution has created a common understanding of risk to help experts in disaster risk reduction, crisis management, climate change and sustainable development.
What Impact Does Climate Change Have On Our Health?
UKHSA is one of the founders of the Health and Climate Working Group of the National Public Health Institutions (IANPHI) and the Cochrane Group. We recently co-led the conceptual development of two position papers with IANPHI (Health and Climate Change Action Roadmap) and the WHO Regional Office for Europe (“Zero Regrets: Scale-up for Climate Change Mitigation and Adaptation to Health”). . WHO European Region).
Looking to the future, we are currently working on the fourth version of the Health Consequences of Climate Change for the UK – a major regular report, last published in 2012, that contributes to the UK’s National Adaptation Programme.
The report will take into account the latest projections of climate change in the UK and assess the health risks associated with climate change, such as weather and its extremes (temperature, floods, droughts and bushfires), air pollution, allergens, UV radiation, disease infectious, mainly caused by a vector. . diseases (transmitted by ticks and mosquitoes), water-borne and food-borne diseases.
A new aspect of the report includes an assessment of the role that adaptation actions (such as changes to our living environment or habits) can play in reducing the impact of climate on health.
Chapter 1: Climate Change And Human Health
As part of the National Adaptation Programme, UKHSA is developing and implementing a single weather and health plan to replace the UK’s heatwave and coldwave plan. It will provide updated guidance on hot and cold weather, droughts and floods based on national and international scientific evidence.
We need public health response steps to reduce the impacts of climate and environmental change on our health.
This will include strengthening the scientific evidence to guide our actions, including interventions and adaptations that reduce the health risks associated with climate change, and understanding why these interventions are effective.
We will need to work with funders to address evidence gaps and find new ways to make evidence available to policymakers.
Emerging Climate And Health Threats Of Fossil Fuels
A key part of this is the development of risk assessment tools and measures of impact and outcomes at national and local levels.
In all our work we must build stronger and deeper relationships with local authorities, national governments and academia.
Over the coming months, we will combine our work on climate and health in a new UKHSA-based Center for Climate Security and Health, which will help us take the steps needed to respond to critical health impacts. the climate crisis, especially extreme weather changes that are affecting the environment that provides us with clean air, food, water, shelter and safety.
, along with other natural and artificial health stressors, threaten human health and well-being in many ways. Some of these health effects occurred in the United States.
Frequently Asked Questions About Climate Change
As the effects of climate change are expected to intensify over the next century, existing health risks will increase and new ones may emerge. Understanding how the climate is changing and how this change may impact human health can help inform decisions to mitigate (reduce) the magnitude of future climate change, suggest public health priorities, and help identify research needs.
There is no doubt that the Earth has warmed over the last century. Observations of air and sea air, sea level, and snow and ice have shown this unprecedented change over decades and millennia. The main cause of the observed warming is human influence.
Events, rising sea levels and melting snow and ice have disrupted people’s lives and impacted many sectors of the American economy.
The concepts of climate and weather are often confused. Weather is the state of the atmosphere at a specific time and place. Weather patterns vary greatly from year to year and from region to region. Common aspects of weather are the temperature, precipitation, clouds, and wind that people experience throughout the day. Severe weather conditions include hurricanes, tornadoes, blizzards and droughts. Climate is the average weather conditions that persist for decades or longer. Although weather can change in minutes or hours, recognizing climate change requires observations over decades or centuries. Climate change includes increases and decreases in temperature and precipitation, changes in the risk of certain types of severe weather events, and changes in other features of the climate system.

Climate and weather changes vary at local and regional scales (Figure 1.1). Some of the climate and weather changes observed in the United States include:
Time series of the 5-year average number of extreme two-day precipitation events averaged over the United States from 1900 to 2014. The number is expressed as a percentage difference from the average over the entire period. It is based on 726 stations that have precipitation data on at least 90% of days during this period. An event is considered extreme if the amount of rainfall exceeds the once-a-year threshold. (Image source: based on Mellilo et al. 2014)
Projections of future climate conditions are based on the output of climate models: sophisticated computer programs that simulate the behavior of the Earth’s climate system. Climate models are used to predict changes in the climate system under various possible scenarios. This scenario describes future changes in the concentration of greenhouse gases in the atmosphere,
, other human impact on climate and natural factors. Combined using a set of scenarios called the final climate model simulation set
The Health Effects Of Global Warming: Developing Countries Are The Most Vulnerable
The actual future concentrations of greenhouse gases and the resulting magnitude of future climate change will continue to be largely determined by the choices people make.
The RCP and temperature increase associated with this scenario are described in more detail in Annex 1: 2014 NCA Technical Support Document.
Changes in mean annual temperature (left) and precipitation (right) for 2021–2050 and 2041–2070 compared to the 1971–2000 mean for RCP6.0.
. The RCP6.0 pathway projects global mean temperature to increase above the 1901-1960 global mean temperature by 2100 (further details are described in RCP Annex 1: Technical Support Document). The temperature increase in the United States in this situation is 2°F
