How Global Warming Affects Human Beings

Global warming has an impact on human health. The noted and expected danger connected to weather will worsen the impacts on human health.


How These Impacts affect People

Erythromelalgia represents an effective illustration of how global warming has affected health. This vascular illness is mainly caused by alteration in temperature that causes symptoms such as searing pain, raised temperature, inflammation and erythema. This mostly affects feet and hands.


According to a research in China, the prevalence of Erythromelalgia seems to be very widespread in southern China. This is possibly because of a drastic drop in temperature after a huge rise of temperature and how this affects the body.


How Infectious Illnesses are affected

Varying weather and warming oceans are leading to intense climate patterns that have led to a rise of contagious illnesses; existing and upcoming.


In some regions, these intense climate patterns are forming prolonged rainy seasons as well as long spans of famine in others. In addition, it presents new weather to varied areas.


These prolonged seasons are forming weather that can maintain vectors for an increased length of time. This enables them to develop fast and also forms weather that facilitates the presentation of new vectors and existence.


Effect of Intense Climate

When climate becomes intense, this is a sign of an erratic climate. Weather variation brings about two key impacts;


  • Warming
  • Huger climate alteration

This signifies that all over the world, millions of individuals experience increased danger of contagious illness. El Nino presents an intense climate pattern that is many times to blame for raised precipitation. This leads to flooding, forming a better thriving area for many vectors which transmit as well as lead to contagious illnesses.


Effect of Weather which is warmer and wetter

Illnesses caused by mosquito are likely to be the hugest risk to people, since they are inclusive of yellow fever, malaria, dengue fever, elephantiasis and Rift Valley fever.


According to research, the spread of these illnesses is higher in regions that have gone through severe famine and drought. Flooding leads to increased standing water, where mosquitoes can reproduce. It has been indicated also that these vectors can feed more in warmer weather and develop quicker.


Effect of Warmer Oceans

As oceans become warm, they turn into a breeding area for the development of poisonous algae (referred to as red tides) as well as cholera.


With the rise of rates of phosphorus and nitrogen inside the oceans, the cholera germs that reside inside zooplankton stir from their inactive form.


Varying winds and altering ocean currents propel the zooplankton to the coastline taking the cholera germ with it. In turn, this poisons drinking water, resulting in cholera pandemics. Rise in flooding leads to rise in cholera outbreaks, since floodwaters transport the germs and invade the supply of drinking water.


A connection has also been made between cholera pandemics and El Nino, since this climate pattern makes shoreline waters warm, leading to fast increase of cholera germs.


Malaria

Malaria is a parasitic illness caused by mosquito. It affects people as well as other animals. It starts when a diseased female mosquito bites, depositing the parasite via its saliva, inside the circulatory system of the diseased host.


After this, it goes via the bloodstream inside the liver; here, it is able to develop and breed. The illness leads to signs, which mainly include headache, fever, anemia, tremors; in serious instances, it can lead to death or coma.
