What is Global Warming?
Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities like burning fossil fuels and deforestation. This leads to changes in climate patterns, such as rising temperatures, extreme weather events, and sea level rise.
Key facts
Global warming is causing our planet’s temperatures to rise at an alarming rate. This change disrupts the balance of our climate, which in turn affects human health in several ways.
- Temperatures are soaring: Records show that Earth’s average surface temperature has increased by about 0.9 degrees Celsius since the late 19th century. A significant portion of this warming has occurred in the past 35 years.
- Ice is melting rapidly: The polar ice caps and glaciers are shrinking faster than ever, contributing to rising sea levels. As the ice melts, it poses a threat to coastal communities and leads to habitat loss for cold-climate species.
- Extreme weather events have intensified: Heatwaves, hurricanes, and other extreme weather occurrences have become more frequent and severe due to climate shifts. These events lead to loss of life, property damage, and heightened stress on public health systems.
- Sea levels are on the rise: Oceans have absorbed much of this increased heat, with the top 100 meters showing warming of more than 0.33 degrees Celsius since 1969. Sea levels worldwide have risen by about eight inches in the last century.
- Species go extinct as habitats change: Many animals do not survive because their environments become unsuitable for their existence. This biodiversity loss can upset ecosystems and harm human food sources.
- Air quality has worsened: Higher temperatures contribute to poor air quality that aggravates heart and respiratory diseases among vulnerable populations like children and the elderly.
- Diseases spread easier Pest populations like mosquitoes thrive in warmer climates, spreading diseases such as malaria and dengue fever more widely.
- Agriculture feels the strain: Changes in weather patterns affect crop yields negatively which can lead to food shortages and malnutrition.
Overview
Global warming poses a significant threat to human health, with extreme heat waves leading to heat-related illnesses and exacerbating heart diseases. Changes in precipitation patterns can result in water contamination, creating a breeding ground for pest-related diseases.
Vulnerable populations such as the elderly and those with limited access to healthcare services are at higher risk of suffering from the health impacts of climate change. Urgent action is needed to address these issues, both on a governmental level and through individual responsibilities.
To tackle this pressing issue, it’s essential for governments to implement policies that reduce environmental pollution and protect vulnerable communities from the adverse effects of global warming.
Climate Change and Health
Climate change has wide-ranging impacts on human health, including heat-related illnesses, pest-related diseases, and the increased spread of infectious diseases. Certain populations are also more vulnerable to these health risks due to their socio-economic status or geographical location.
How climate change impacts health
Climate change directly impacts health in several ways. Heat-related illnesses, such as heat stroke and dehydration, are becoming more common due to rising temperatures. Infectious diseases spread faster in warmer climates, leading to outbreaks of mosquito-borne illnesses like malaria and dengue fever.
Additionally, changes in weather patterns contribute to an increase in respiratory problems as air quality declines. The impact of climate change on health is a pressing concern that requires immediate attention from individuals, communities, and governments.
Pest-related diseases are another consequence of climate change. As temperatures rise, pests thrive and expand their range into new areas which can lead to a higher risk of vector-borne diseases like Lyme disease and West Nile virus.
Vulnerable populations
Vulnerable populations, such as the elderly, children, and those with pre-existing health conditions, are at higher risk from the effects of global warming. Heat-related illnesses can disproportionately affect these groups due to their limited ability to regulate body temperature.
Additionally, pest-related diseases spread more easily in warmer climates and may pose a greater threat to vulnerable communities. Ensuring access to healthcare and public health interventions for these groups is crucial in mitigating the impact of climate change on human health.
Addressing the specific needs of vulnerable populations requires targeted policies that prioritise their well-being. This includes measures such as heat-resilient housing, improved urban planning to reduce heat islands, and adequate healthcare infrastructure to manage climate-related health risks.
Examples of public health risks
Climate change poses a range of risks to public health, affecting both physical and mental well-being. Some of the key public health risks resulting from global warming include:
- Heat-related illnesses: As temperatures continue to rise, there is an increased risk of heat-related illnesses such as heat exhaustion and heatstroke, particularly among vulnerable populations.
- Pest-related diseases: Rising temperatures and changes in precipitation patterns can lead to the proliferation of disease-carrying pests like mosquitoes and ticks, resulting in a higher incidence of illnesses such as malaria, dengue fever, and Lyme disease.
- Water contamination: Changes in climate patterns influence water quality, leading to contamination that can result in outbreaks of waterborne diseases such as cholera and dysentery.
- Respiratory diseases: Poor air quality due to increased air pollution and allergens exacerbates respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD).
- Mental health impacts: The stress and trauma caused by natural disasters linked to climate change, along with the uncertainty about the future, can contribute to mental health challenges including anxiety, depression, and post-traumatic stress disorder (PTSD).
Health Effects of Global Warming
Global warming has been linked to an increase in respiratory and heart diseases due to air pollution. Pest-related diseases are on the rise as warmer temperatures provide a more hospitable environment for pests.
Additionally, water contamination and mental health issues have also been associated with the effects of global warming.
Respiratory and heart diseases
Global warming contributes to the worsening of respiratory and heart diseases. As temperatures rise, air quality deteriorates due to increased pollution levels and the proliferation of allergens such as pollen.
This leads to a higher prevalence of asthma, bronchitis, and other respiratory illnesses. Additionally, extreme heat can strain the cardiovascular system, leading to an increase in heart attacks and other related conditions.
Furthermore, climate change also facilitates the spread of infectious diseases like dengue fever and malaria through expanded habitats for disease-carrying vectors. These health impacts highlight the urgent need for collective action to mitigate global warming’s effects on human health.
Pest-related diseases
Pest-related diseases pose a significant threat to human health in the context of global warming. As temperatures rise, pests such as mosquitoes and ticks are able to thrive in new areas, spreading diseases like malaria, dengue fever, and Lyme disease.
These vectors find more hospitable environments for breeding due to changing climate patterns. Additionally, changes in rainfall distribution can lead to an increase in rodent populations, heightening the risk of diseases such as hantavirus pulmonary syndrome and leptospirosis.
Heatrelated illnesses
Water contamination
Water contamination poses a severe risk to human health due to global warming. Rising temperatures can lead to increased algal blooms in water bodies, which can release toxins harmful to humans and marine life.
Additionally, extreme weather events linked to climate change, such as heavy rainfall and flooding, can overwhelm sewage systems and cause contamination of drinking water sources with harmful bacteria.
These factors contribute to the spread of waterborne diseases like cholera and typhoid fever, posing a significant threat to public health.
Furthermore, the melting of polar ice caps from global warming leads to rising sea levels that can contaminate freshwater reserves with saltwater intrusion. This jeopardises essential drinking water supplies for communities around the world.
Mental health
Global warming can have a significant impact on mental health. The stress and anxiety caused by extreme weather events, loss of homes, and economic instability can take a toll on mental well-being.
Furthermore, the displacement and migration due to climate-related disasters can also lead to heightened psychological distress and trauma among affected populations.
