When one hears the phrase “global warming,” what often comes to mind is melting ice caps and warmer winters but most people are horribly unaware of the effects that global warming will have on human health. Food shortages, contaminated water, extreme weather, and deadly heat threaten the world because of the warming temperatures of our earth. The effects of these can be seen today and their influence will be magnified in the not-so-distant future. But the most dangerous threat we face from global warming is the spread of disease. The term global warming refers to an unnatural and accelerated increase in temperature. These increases are mostly due to the release of heat trapping gases such as methane, nitrous oxide, halocarbons, and ozone. Almost all of these are byproducts of human commerce and activity. Things like car emissions, raising livestock, producing industrial chemicals and even deforestation add more of these chemicals to our air, throwing off the natural balance of our atmosphere (Berger 30). The mean temperature on Earth has risen about 1 degree Fahrenheit since the industrial revolution. It has been predicted that the climate could increase about 2.2 to 10 degrees in the next 100 years (EPA 2 0f 2). This data is supported by countless satellites, weather studies, oceanic studies and computer models of world wide climate patterns and this warming is inevitable (Shute et al 44). When doing global warming research one must be cautious, because the biggest source of misinformation on global warming is the fossil fuel companies who will have you believe that global warming and it’s ill effects are nothing but scientific hype.

Global warming is described as an increase of average temperature throughout the globe over an extended period of time. Typically when scientists use the term global warming they use it to describe rising temperatures due to human actions such as the burning of fossil fuels and release of aerosols into the atmosph...
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
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
There are many things that can impact the economy, but many people would not think that global warming has much of an effect on it. Global warming is continuing to become a very large concern for people across the world. This topic is very controversial due to the fact that many people fail to believe that global warming even exists. In this case, it will often be looked at as climate changes instead.
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
Research has proven that over the past 100 years, the average temperature of the Earth has risen approximately 1 degree Fahrenheit (1°F), increasing at a rate twice as fast as noted for any period in the last 1000 years (Afzal, 2007). Global warming is happening, climate change is occurring and the health effects of climate change will necessitate an informed response by health care professionals. Global warming results from destruction of the ozone layer of the atmosphere and consequent warming of the earth’s surface (Friedman, 2013). The purpose of this paper outline the health concerns related to global climate change, including health promotion and health protection that a Bachelor’s of Science (BSN)-prepared nurse could implement. Health concerns related to global climate change
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.
Global warming is the earth slowly heating up and there are many factors to it. It is causing melting of the poles and water temperatures rising. One main factor causing this is carbon dioxide(CO2) emissions from the burning of fossil fuels to create energy. These gases being released into the atmosphere are also known as greenhouse gases. These gases trap heat within the atmosphere. While we need energy for many everyday uses there are a lot cleaner ways to make the energy. The public needs to be informed on the negative effects of creating energy this way and ways to make clean energy.
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
The Impact of Global Warming on Human Health Throughout the world, the presence of particular diseases and other threats to human health depend largely on the local climate. Extreme variation in temperature can directly, and indirectly, cause the loss of human life. The threat of a gradual increase in temperature could be catastrophic to the world, as we know it. In 1999, a heat wave killed more than 250 people in Chicago alone (Union of Concerned Scientists). Many consider such an event a natural disaster.
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. While it changes the Earth’s climate it takes away different species that we depend on and some which other species depend on and also effect (in a bad way) the environment in which we live and can cause permanent damages to humans, animals, plant which will change the whole chain of ecosystem.
The Centers for Disease Control have been involved in studying global warming's effect on human health. Its affect on the climate can adversely affect humans. Plagues have been attributed to global warming. An increase in temperature can result in a longer life cycle for diseases or the agents spreading them.” Global warming will lead to more precipitation, which enables infectious diseases to be more easily contracted and spread.” (2) Effects of global warming on human health might not be immediately detected.
The common definition of global warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants (Global warming, Wikipedia). Moreover, the effects of global warming will bring ecological and social changes. Because there is no exact way to predict the effects of global warming, it is almost impossible to say how strong global warming will affect life in the future.
