What Is The Cause And Effect Of Climate Change – Climate change poses a fundamental threat to human health. It affects the physical environment as well as all aspects of both natural and human systems, including social and economic conditions and the functioning of health systems. It thus multiplies the threat, undermining and potentially reversing decades of progress in health care. As climate conditions change, we are experiencing more frequent and intensifying weather and climate events, including hurricanes, heatwaves, floods, droughts and wildfires. These weather and climate hazards affect health both directly and indirectly, increasing the risk of mortality, noncommunicable diseases, the emergence and spread of communicable diseases, and health emergencies.
Climate change is also impacting our health workforce and infrastructure, reducing our ability to achieve universal health coverage (UHC). More importantly, climate shocks and increasing stresses such as changing temperature and rainfall patterns, drought, floods and rising sea levels are worsening the environmental and social determinants of physical and mental health. Climate change impacts every aspect of health, from clean air, water and soil to food systems and livelihoods. Further delay in addressing climate change will increase health risks, undermine decades of improvement in global health, and contradict our collective commitment to ensuring the human right to health for all.
What Is The Cause And Effect Of Climate Change
The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) concluded that climate risks are emerging faster and will become more severe sooner than previously expected, and that it will be more difficult to adapt to increased global warming.
Climate Change Impacts On Plant Pathogens, Food Security And Paths Forward
Additionally, the study shows that 3.6 billion people already live in areas most vulnerable to climate change. Despite their minimal contribution to global emissions, low-income countries and small island developing states (SIDS) experience the worst health impacts. In vulnerable regions, mortality rates from extreme weather events over the past decade were 15 times higher than in less vulnerable regions.
Climate change impacts health in a variety of ways, including causing death and illness from increasingly frequent extreme weather events such as heat waves, hurricanes and floods, disruption of food systems, increased incidence of zoonotic diseases, and food, water and vector-borne diseases. . infectious diseases and mental health problems. In addition, climate change undermines many of the social determinants of good health, such as livelihoods, equity, and access to health care and social support structures. These climate-sensitive health risks are disproportionately felt by the most vulnerable and disadvantaged populations, including women, children, ethnic minorities, poor communities, migrant or displaced people, older people and people with underlying health conditions.
Figure: Overview of climate-sensitive health risks, exposure pathways and vulnerabilities. Climate change affects health both directly and indirectly, and is largely mediated by environmental, social and public health determinants.
Although climate change clearly impacts human health, it remains difficult to accurately assess the magnitude and impact of many climate-sensitive health risks. However, scientific advances are gradually allowing us to link increases in morbidity and mortality to global warming and to more accurately determine the risks and extent of these health threats.
Climate Change, Causes And Effects
Data shows that 2 billion people lack access to safe drinking water and 600 million suffer from foodborne illnesses each year, with children under 5 years of age accounting for 30% of foodborne deaths. Climate stressors increase the risks of water- and food-borne diseases. In 2020, 770 million people faced hunger, predominantly in Africa and Asia. Climate change is affecting the availability, quality and diversity of food, exacerbating food and nutrition crises.
Changes in temperature and precipitation contribute to the spread of vector-borne diseases. Without preventive measures, deaths from such diseases, currently more than 700,000 per year, could rise. Climate change causes both immediate mental health problems such as anxiety and post-traumatic stress, and long-term distress due to factors such as population displacement and disruption of social cohesion.
Recent studies link 37% of heat-related deaths to human-caused climate change. Heat-related deaths among people over 65 have risen by 70% in two decades. There are 98 million more people food insecure in 2020 than the 1981–2010 average. Conservative projections suggest there will be an additional 250,000 additional deaths per year by the 2030s due to the effects of climate change on diseases such as malaria and coastal flooding. However, modeling challenges remain, particularly in accounting for risks such as drought and migration pressure.
The climate crisis threatens to reverse the last 50 years of progress in development, global health and poverty reduction, and further widen existing health inequalities between and within populations. This seriously threatens the implementation of universal health coverage in a variety of ways, including exacerbating the existing burden of disease and exacerbating existing barriers to accessing health services, often at a time when they are most needed. More than 930 million people—about 12% of the world’s population—spend at least 10% of their household budget on health care. Because the poorest are largely uninsured, health shocks and stresses are already pushing about 100 million people into poverty each year, and the effects of climate change are exacerbating this trend.
Aerosols: Small Particles With Big Climate Effects
In the short to medium term, the health impacts of climate change will be determined primarily by the vulnerability of populations, their resilience to current rates of climate change, and the extent and pace of adaptation. Long-term impacts will increasingly depend on the extent to which transformative action is now taken to reduce emissions and avoid dangerous temperature thresholds and potential irreversible tipping points.
While no one is immune to these risks, people believe that the climate crisis harms health first and worst where people contribute least to its causes and are least able to protect themselves and their families from it: people with low incomes and disadvantaged countries and communities.
Addressing the health burden of climate change highlights the equity imperative: those most responsible for emissions should bear the highest costs of mitigation and adaptation, with particular attention to health equity and prioritization of vulnerable groups.
To prevent catastrophic health consequences and prevent millions of deaths related to climate change, the world must limit temperature rise to 1.5°C. Past emissions have already made some level of global temperature rise and other climate change inevitable. However, global warming of even 1.5°C is not considered safe; Each additional tenth of a degree of warming will cause serious harm to human life and health.

Climate Change Impacts
Climate change is a change in average weather conditions in a region over a long period of time. One component of climate change is global warming, the long-term warming of the Earth due to greenhouse gas emissions.
Over the past century, changes in human activity have disrupted the planet’s natural energy balance, mainly through the burning of fossil fuels, which release additional carbon dioxide into the air. These gases trap excess heat near the Earth’s surface, leading to a steady increase in surface-level temperatures over the past decades. This is known as global warming.
The effects of climate change range from rising sea levels and more frequent extreme weather events to loss of biodiversity and increased risk of disease. Climate change affects all forms of life: humans, plants and animals.
More than 800 million people—11% of the world’s population—are already likely to experience the effects of climate change in their daily lives, including an increase in the frequency of natural disasters.
