The Impact Of Climate Change On Human Health

The Impact Of Climate Change On Human Health – Climate change is the single greatest health threat facing humanity, and health professionals around the world are already responding to the health damage caused by this ongoing crisis. unfold.

The Intergovernmental Panel on Climate Change (IPCC) has concluded that to avoid catastrophic health impacts and prevent millions of deaths related to climate change, the world must limit the increase in temperature to 1.5°C. Past emissions have already made a certain level of global temperature rise and other climate changes inevitable. Global warming of even 1.5 ° C is not considered safe, however; every tenth of an additional degree of warming will have a serious effect on people’s lives and health.

The Impact Of Climate Change On Human Health

While no one is safe from these risks, people’s health is being damaged first and worst by the climate crisis, the least people contribute to its causes, and they are the -less able to protect themselves and their families against it – people with low incomes. and disadvantaged countries and communities.

The climate crisis threatens to undo the last fifty years of progress in development, global health, and poverty reduction, and to further widen existing health inequalities between and within the -populations. It seriously jeopardizes the achievement of universal health coverage (UHC) in several ways – including by increasing the existing burden of disease and by exacerbating existing barriers to access to health services, often in -the times 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 to pay for health care. With the poorest uninsured, health shocks and stress already currently push around 100 million people into poverty each year, with the impacts of climate change exacerbating this trend.

Climate change is already impacting health in many ways, including by leading to death and disease from increasingly frequent extreme weather events, such as heat waves, storms and floods, the disruption of -food systems, increases in zoonoses and food, water and flooding. vector borne diseases, and mental health issues. In addition, climate change is undermining many of the social determinants of good health, such as livelihoods, equality and access to health care and social support structures. These climate-sensitive health risks are felt disproportionately by the most vulnerable and disadvantaged, including women, children, ethnic minorities, poor communities, migrants or displaced persons, older populations, and those with health conditions underlying.

An overview of climate-sensitive health risks, their exposure pathways and vulnerability factors. Climate change affects health both directly and indirectly, and is strongly mediated by environmental, social and public health determinants.

Although it is unequivocal that climate change affects human health, it remains challenging to accurately estimate the scale and impact of many climate-sensitive health risks. However, scientific advances progressively allow us to attribute increased morbidity and mortality to human-caused warming, and to determine more precisely the risks and scale of these threats to health.

Addressing The Impacts Of Climate Change On Human Health

In the short to medium term, the impacts of climate change on health will be determined mainly by the vulnerability of populations, their resilience to the current rate of climate change and the extent and -adaptation step. In the longer term, the effects will increasingly depend on the extent to which transformative action is taken now to reduce emissions and avoid breaching dangerous temperature thresholds and potential irreversible tipping points.

In the densely populated Northeast, Asian tiger mosquitoes are poised to triple their range before 2045 — doubling the number of people potentially exposed to the disease from 18 million to more than 30 million .

Climate Change And Health

But we are not helpless against such threats, according to a recent report co-authored by researchers at Stanford University. A few weeks before the 2016 election, the authors presented the report to the two presidential transition teams. Titled “Health: The Human Face of Climate Change, an Outlook and Recommendations for the Next President of the United States,” the report recommended that a future administration begin a formal ten-year emergency response to climate change. in the climate, led by the US State Department, and a framework. climate change as a global health security issue —  in other words, an acute public health threat to populations worldwide.

The report “The Human Face of Climate Change” was one of a series of 14 climate reports that emerged from a 2016 conference at Stanford entitled “Setting the Climate Agenda for the Next U.S. President.”

One of the report’s three authors, Katherine Burke, MM, MSc, who is deputy director of the Center for Innovation in Global Health at Stanford, said that when she and her co-authors began writing the report, they believe it was an extraordinary opportunity to make an impact. Its co-authors are Michele Barry, MD, Stanford professor of cine and director of the Center for Innovation in Global Health; and Diana Chapman Walsh, PhD, senior adviser to the center and president emeritus of Wellesley College.

Although the report has received no response from President Trump or his administration, the advice it contains still provides a valuable framework for dealing with climate change and health, Walsh said.

Experts agree that the Earth is warming dangerously and that this warming is due to the burning of fossil fuels and other human activities. The damage in ecosystem disruption, sea level rise and increasingly intense storms are all well documented. So, increasingly, are the effects of the rapidly changing climate on human health.

Both increased average temperature and severe heat waves have similar effects on morbidity and mortality through heat-related illnesses such as heat stroke and heat exhaustion. “The clearest thing is the impact of the increase in ambient temperature,” said Mark Cullen, MD, professor of cine and biological data science “With every degree centigrade increase in high temperatures summer, there is a predictable increase in total mortality.”

Added Cullen, who did not contribute to the report but is an expert on population health, “Most of it is a ‘harvesting function’ like the flu, meaning people are less often completely healthy. to suffer or die; it’s people with other chronic illnesses who are at risk of dying earlier during heat waves.”

In addition, healthy people who normally work outside during the heat of the day can get sick or even die from the extreme heat. Farm workers, road workers and roofers are among those at risk. In a warmer world, the number of days when it is too hot to work outside safely is expected to increase dramatically. Places like Texas, which once had 10 to 20 days a year of temperatures greater than 100 degrees, could see more than 100 a year by the end of the century, according to the National Oceanic and Atmospheric Administration.

Together We Can Defend Against Climate Threats To Food Safety

Infectious diseases will also worsen, as disease vectors such as mosquitoes and ticks increase in number and spread. And climate change has hundreds of other indirect effects on health. For example, our cows and chickens are just as vulnerable as we are to temperatures of 100 degrees and increasingly persisting for days or weeks.

Ocean warming and acidification are together killing coral reefs and destroying marine fisheries, the primary food for about 2 billion people in Asia and the Pacific. Valuable agricultural lands around the world are threatened by drought or, in places like Bangladesh, flooding from rising seas and floods.

“If your food basket is not producing, then your city is going to be in serious trouble,” Burke said.

The consequences of shattered food supplies spread outward, causing economic deprivation, social upheaval, food shortages and the displacement and forced migration of millions. These then lead to violence, trauma and physical and mental disability.

For example, an extreme drought in Syria between 2006 and 2009 — which experts believe was due to climate change — caused massive crop failures, which, in turn , led to the migration of 1.5 million people from farms to cities. Such displacement played a role in the subsequent uprising against President Bashar al-Assad in 2011, experts argued.

The health care community already recognizes that tracking, studying and addressing the health impacts of climate change is critically important to strengthening the resilience of societies around the world.

The table shows some of the expected health effects of climate change due to worsening air quality.

Many institutions have started integrated programs to consolidate what is known and what questions need to be answered. For example, The Lancet, an ecu journal, has set up an international research collaboration called “Lancet Countdown: Tracking progress on health and climate change.”
