The Effects Of Climate Change On The Earth

Current environmental health problems that will likely exacerbate due to climate change include changes in air and water quality, and increase in parasite growth and chemical pollutants.

The earth’s climate has been changing and will continue to do so in the future. It is only going to keep on getting worse and it is getting to the point where humans will most likely end up in a situation of life threatening diseases and even death. Contagious diseases are spreading menacingly due to weather extremes as heat wave, droughts, cyclones, floods, and tornados (Dhaka). That is just the start of the effect of climate change and its consequences. Many scientists have already warned that millions of people would die in this century because of climate change unless the major reduction in greenhouse gas emissions is made (Dhaka). However, there are more than just reducing greenhouse gas emissions to help solve for climate change.

(WHO 2015) It is now generally acknowledged that the global climate is changing as the earth becomes warmer, in particular due to the burning of fossil fuels. Human health may be impacted by shifting the geographic range and seasonality of infectious diseases, possibly increasing vector borne disease rates, disturbance of food-producing ecosystems, and increasing the frequency of extreme weather events such as droughts, cyclones, floods and bush

Climate change increases the possibility of extreme weather events which in turn makes disease transmission more frequent in poor, developing countries. The weather event known as El Nino has been determined to be one of the leading environmental factors that influences disease. El Nino is a band of warmer than average water, which

Food borne illnesses such as salmonella, shigellosis, and other bacteria related food poisonings will increase due to the rapid rise in temperature. These diseases can cause gastrointestinal problems, even death. An increase in rain flow causes flooding which can lead to an increase in food contamination. Water borne diseases Cryptosporidium and Giardia increase with heavy rainfall, and these parasites can be very harmful to the human body. Animal borne diseases such as Lyme disease and West Nile virus will increase as air temperature rises. Ticks and mosquito population will grow rapidly and conditions will be favorable for new strains of the diseases listed above. These diseases will have an effect on my career as a Forensic

As a result of the mosquitoes physically being able to occupy a different vector, certain diseases also begin to expand to occupy that vector as well. As stated by an article about the population dynamics of mosquitoes, “global changes . . . lead to an extension of the distribution areas of certain mosquito species and the emergence of associated vector-borne diseases” (Ezanno et al.). As mosquitoes shift the vector of where they live as a result of this global warming, they bring what they have with them. In this case, this means that the mosquitoes bring these diseases with them throughout this new vector. Not only do mosquitoes bring these diseases with them to these new places, depending on the climate in this new area, certain diseases

Vector-borne infectious disease: As the climate changes, temperatures increase, and precipitation levels rise, causing species patterns to change, such as those of mosquitos and ticks. In addition, it too introduces new pests and pathogens into new regions, such as the Zika virus, which has shown to be fatal to the human population.

From the article “Climate Change and Your Health” the author replies that Rising temperatures will likely lead to more frequent and severe heat waves, natural disasters, poor air quality and spreading diseases. For example, in the year of 2006 the heat within two weeks caused 655 deaths and in 1995 over 700 people died due to excessive heat in Chicago. Hot weather kills more Americans than any other despite disasters. Global warming also means 650 million people who live on or near land will be threatened by sea level rise. In the article “20 Countries Most At Risk From Sea Level Rise” it shows that “147 to 216 million people live on land that will be below sea level or regular flood levels by the end of the century”. This means that more than 200 million people may die because of global warming. In addition, people are more likely to get sick because of temperature changes. Most of the bugs like warm temperature especially the bugs like mosquitoes and flies. People always get bite by mosquitoes in summer, but can rarely see mosquitoes on winter or fall. Therefore global warming would cause summers become longer these insects like mosquitoes can keep active for longer seasons and also in wider areas. Insects like mosquitoes have capable of carrying and transmitting diseases like Dengue Fever which greatly increasing the risk of people to get sick. Rising temperatures are more likely result in

Global warming may increase the risk of some infectious diseases, like malaria, dengue fever, yellow fever, and encephalitis. These diseases are spread by mosquitoes and other insects, and could become more common if a rise in temperature allows those insects to live farther north. Also, the increase in rainfall that is likely to occur with an increase in global temperature would serve to help increase the reproduction of the vectors. In February 1999, Britain's Institute of Animal Health linked outbreaks of the lethal horse fever virus in Africa to the El Nino phenomenon. The warming and increase in rainfall in Africa caused by El Nino led to many more horses being bitten by infected vectors. The scientists said their research shows this pattern is likely to happen with other vector-borne diseases when global warming occurs. Increased temperatures could also reduce the gestation periods of disease vectors, which could aid the breeding of strains resistant to pesticides. Scientists also hypothesize that algae

Animal- borne diseasesbefore there was high climate change, obviously there were less diseases that could be spread by pathogens

In the introduction of Thomas Gale Moore’s essay, he states that “Threats of global warming are bringing on a plague… infestation we speak of is a plague of misinformation, infecting the public consciousness and blurring the issue of the effects of climate change on human health in a swarm of anxiety and confusion”. One of his sources states that “global warming is not the current problem. It is a collapse in public health measures, an increase in drug resistance in parasites, and an increase in pesticide resistance in vector

Due to climate change both the land and the marine distribution is changing, causing numerous problem for human beings. The direct impact of climate change is on the food availability due to redistribution of species, since the areas that are suitable for crop production will either become too dry or will be under water creating a shortage of food worldwide. Animals are migrating to new areas to increase their survival chance, making it difficult for humans to access the same food that they once had before the migration. Fishes are the best example of species shift, due to climate change, the water temperature is rising causing the fishes to travel deep down into the ocean where it is cooler. As the fish travels further down, harvesting fish will become expensive causing economic crises eventually affecting the human well-being. On the other hand, the changing climate change is also posing new health risks for humans, such as some countries are now suffering from malaria, a disease transmitted by mosquitoes. Due to a rise in worldwide temperature, mosquitoes can travel to numerous suitable places. An indirect effect of climate change will be the stress that the plants are facing now. Because of lack of trees on land, the carbon dioxide rate in the atmosphere is increasing which is raising the temperature and melting the tundra region, thus raising the water level. Because of climate change, humans are encountering various problems that can only be solved if the governments take initiative and find a solution for the situation. If world leaders wait any longer, a major catastrophic situation can occur that will dramatically affect human

Climate is the weather conditions over a long term. For millions of years, the earth kept changing between hot and cold, and wet and dry. As the earth warmed and cooled, plants and animals appeared and disappeared. People have had to change their way of life many times as plant and animal life changed. Since the industrial revolution, the humans built many factories and invented lots of electronic devices. They emit harmful gases called greenhouse gases like carbon dioxides and ozone, which affects our planet. However, it is difficult for people to recognize the effects because the process of climate change takes a long time. Furthermore, people think it is so far away. For example, as in Antarctica, all the icebergs are melting, which is

Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007)

Climate change is present in Earth due to the greenhouse gases that are held or trapped in heat in the atmosphere by absorbing infrared radiation and emitting it back in high amounts, causing global warming among other factors that contribute to it; such as, the burning of fossil fuels and the industrial revolution. Due to these actions, society will begin to face an increase in diseases in different regions that will mostly affect those that face poverty, the elderly, and children. Slowly those diseases will also lead to the death of many people due to the temperature that continues to rise.
