Climate change endangers a human health in many ways, including weather, wildfire, and air quality. Environmental consequences of climate change, such as extreme heat waves, rising sea-levels changes in precipitation resulting in flood and droughts, intense hurricanes, and degraded air quality, affects directly and indirectly the physical, social, and psychological health of humans. Rising global temperatures have been caused by the changes in weather and climate, but humans are responsible for the recent climate change and endangers to their health. The climate is always changing and it is also something that affects everyone on a daily basis. Where we go, how we dress and how we choose to spend our days is all based on the weather. We’re …show more content…
Many scientists believe that the greenhouses gases which are produced by humans are the cause of climate change. The development of new policies and strategies will take some time, but some essential principles are already clear. A global problem

How Climate Change Effects Human Health requires a strategy of international dimensions that can translate into regional and local actions.
Just as climate change’s underlying causes are global, its health implications do not respect national boundaries. Impacts in one location, such as infectious disease epidemics or population displacements caused by droughts or rising sea levels, quickly spread across national borders.
According to Implications for International Public Health Policy (2016), coordinated investments in preventive measures; therefore, contribute to the “global public good” of reducing the risk of health emergencies. The government and scientists need to do more to show how climate change endangers human health. Human health is neglected, if not, ignored when it comes to climate change. Despite these potential problems, most Americans don’t look at climate change and their physical well-being. Most Americans think that climate change is a distant issue and
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
As humans, every aspect of our life is reliant on the natural environment, whether it’s the food we eat, the air we breathe, the water we drink, the clothes we wear or the products that are made and sold to create jobs and drive the economy. While Australia’s large agriculture industry may save us from running out of food, global shortages will drive up the price of staples making a trip to the supermarket more expensive. The increased frequency and severity of heatwaves may lead to death and illness, especially among the elderly. Higher temperatures and humidity could see increased mosquito-borne diseases in Aus. Climate change will affect our lifestyle in many ways such as; we will experience more extreme weather events more often, global politics will become unstable, our travel plans will change and some more. Climate change at a basic level will affect our food, health and leisure. Many people could also face war, starvation or losing their
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.
Direct impact from climate change such as air pollution have caused many challenges with children's health. With air pollutants example nitrogen oxide and ozone are likely to increase as countries adapt to hotter temperatures by using energy to use fans etc., Changes in the environment causes children to suffer from both long-term and short-term...
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
The causes of climate change are also known to them that though it is not only the human action playing role but it is the main cause of climate change. The effects of climate change does include harm and loss of environment and organisms but it also has impact on the human health. Semenza (2014) displays an assessment report which states that throughout the 21st century, the rapidly occurring climate change will lead to increase in number of humans with ill health in many regions mainly in those of developing countries where citizens face low income. Semenza (2014) also mentions how there are physiological limits to intense heat exposure and the global climate change will turn some parts of the world which are currently highly populated into uninhabitable even if the global temperature rises by 7 degrees Celsius. Johnson (2014) states how El-Niño-related hydroclimate variability will lead to being intensified under global warming mainly in areas as southern Asia which are already stressed by different droughts, floods, and crop yields. Dettinger, Udall, and Georgakakos (2015) mentions how climate change puts risk and threat on water resources in the western United States to an extent that no other part of the country matches it. Dettinger, Udall, and Georgakakos (2015) also states how recent research and studies strictly point a limited number
Climate change is not often the sole cause of increases in the burden of climate sensitive health outcomes, but it interacts with other public health stresses. The increasing extent and rate of climate change means it is expected to be a major health...
Berry mentions in his article that we need to be aware of our environment and keep it as healthy as possible (Elliott 671). While many of us recognize the general importance of environmental health, such as maintaining crops, having clean air to breathe and water to drink, we greatly underestimate its importance in individual health and its effects on medical practices. With global warming and climate change, we will be, if we are not already, be facing challenges such as decreased soil fertility, access to freshwater, crop yields, and the spread and mutation of infectious diseases (Elliott 690-695). Many ecosystems are heavily influenced by temperature, and climate change can and will drastically change many ecosystems. In the case of crop yields, the change in ecosystems could negatively influence pollinating animals such as bees and hummingbirds, and result in crops not being as well pollinated, and crop yields decreasing. When crop yields drop, we face issues like widespread hunger and famine. In the same vein, infectious diseases are often limited to certain regions because they can only survive in certain conditions. Climate change will change climatic conditions in ways that may facilitate the spread of infectious diseases into new areas, and they may become much more prominent issues than they used to be. Our economies, social stability, and health are all at stake when we damage our environment. Green energy is important now more than ever, and the medical community has done little to convert to sustainable resources for sustainable treatment and health care. As Bednarz describes in “Medicine After Oil,” medical practices rely heavily on petroleum products such as gloves, various plastic products (including heart valves), antibiotics, various gels and
The first part of this essay discusses what the human species has done to deal with the problem of climate change. While some improvements have been made, the problem has not been addressed aggressively enough to stop the damage. What is amazing about this is the denial of so many people that problems exist. If they do realize the risks, they are simply not taking actions to contain the damage.
Thesis statement: The global warming and the resultant climatic change is due to uncontrolled human exploitation of earth and its resources thereby emitting large volumes of greenhouse gases into the atmosphere.
As a future public health professional I have realized that climate change has began to impact human health in various ways such as increased spread of vector-borne infectious diseases, increased respiratory illnesses that are associated with increased air pollution, and childhood cancer. The CDC states that the effects of climate change varies across geographic regions and populations, which has led to the help of CDC’s Climate and Health Program in helping state and city health departments prepare for the specific health impacts of climate change that their communities will face. There are still quite a few health departments that do not have a strategic plan in motion to deal with local health impacts of climate change, which is a huge

In conclusion, many facts point to global warming being detrimental to our world. With scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations being some of the more thought about topics it`s hard not to agree that our world can not continue to be used as it is. Even with some scientists arguing against the topic, our Earth`s orbit changing the temperatures before and have been through hotter and cooler time periods the pros still outweigh the cons. This is why we, as a global population, need to take into consideration the outcome of our planet should we continue to abuse it the way we do. Our earth and resources are not a right but a privilege and we should learn to treat them as such before we no longer have either.
The change in climate has been a topic of controversy across the world throughout the past years. Scientists have done research on how climate changes has changed throughout the years around the world. In the past few years, research shows that climate has changed dramatically in the world. Although climate change is something that occurs normally in nature, there has been substantial evidence that mankind is a contributor to the dramatic increase. Most countries around the world have got together to discuss how to reduce mankind’s contribution to climate change, but there is other countries that still do not consider this as a problem. Research conducted by scientists have supported the idea that climate
