Climate change has impacted human life across the entire globe. Many people across the world are dealing with several implications brought about by this change.
The adverse changes in the weather has been harmful to human being. Though the scientist and researchers in the academic and intergovernmental organizations are working on implementing solutions to the climate changes, they still have not managed to solve this menace.
Human health has become unbearable due to the effects brought about by climate change. The adverse heat has exposed humans to life-threatening infections such as dengue fever.
Generally, many diseased people are suffering from in this 21 century are as a result of weather patterns. Below are several ways in which the life of people living under the earth has suffered thanks to climate changes.
5 Major Effects of Climate Change
• Effects of Heating due to High Temperatures
Human health has been affected by high temperatures, which have caused a lot of heating in various places around the globe. A lot of heat has brought exhaustion, heatstroke, hyperthermia, and even dehydration, which have led to several deaths.
With high temperatures, the existing disease such as hypertension, cardiovascular, respiratory, cerebrovascular, kidney, and diabetes has worsened. The prevalence of these diseases, a lot of premature deaths reported in various countries.
High temperatures have also triggered the vector-borne diseases brought about by mosquitoes, ticks, fleas, and rodents. The reproduction process of these insect parasites mainly depends on the high temperatures. These vectors carry infections such as viruses, bacteria, and protozoa from animals to humans.
The spread of these climate-related diseases mainly depends on both climate and non-climate factors. These factors include land use, socio-economic and cultural conditions, pest control, health, and how humans respond to disease risk.
This has made under developed countries to grapple with these climate-sensitive diseases. In contrast, developed countries can lay down reliable health infrastructure to monitor and manage such conditions.
• The Outbreak of Natural Disasters
Though many countries have tried to manage this disaster before they occur, some countries are still lagging behind due to lack of resources.
Main natural disasters are drought and fires. Wildfires come as a result of stagnant heat, increased drought, and intense heat duration.
These fires emit a lot of carbon resulting in climate change. The fires not only affect human but animals that live in the forests.
The fires also affect the quality of air, posing a lot of health challenges to mankind. Due to the lack of quality air it has become very easy to acquire airborne diseases like asthma, acute bronchitis, and pneumonia.
Ground-level ozone pollution is also worsened by these wildfires and drought. Air pollution generally leads to respiratory illnesses that result to death if not correctly handled.
• Impact of Severe Storms
There are massive surface evaporation resulting from rise in temperatures. This evaporation act as a rain bomb because it increases the number and severity of rain that causes a surge on the magnitude of storms.
Apart from increasing the strength, it also enables the frequency and duration of hurricanes. These hurricanes result in several deaths and a lot of destruction across the globe.
Global warming has made hurricanes to become more frequent. This is brought up by high intensifying rainfall and the high speed of the wind rendering other places inhabitable.
• Effects Brought About by the Rising sea
When there is global warming that increase severity of hurricanes, the seawater level also increases to greater heights. Increased or rising of water and flooding affects the healthy being of humans.
Drinking water, human wastewater treatment, and storm water disposal are exposed, leading to water-borne diseases that are caused by pathogens such as bacteria, viruses, and protozoa.
The outbreak of such ailments can result in death. An increase in the transportation of these pathogens sometimes results in food contamination. The transport, transmission, viability, and multiplication rate of the pathogens in the food chain is normally influenced by global warming.
• Cascade of Consequences
Climate change has impacted both mental and behavioral health conditions in humans. These conditions may result in anxiety, depression, alcohol or substance abuse, post-traumatic stress, and lastly, committing or contemplating suicide.
People with pending mental illnesses are at a higher risk of developing much mental disorder in case of a hurricane. This was even witnessed after a hurricane in Katrina in 2005, where veterans with mental illnesses were adversely affected.
The immediate change of lifestyle of people immediately after the hurricane disaster left many people to contemplate suicide. Women were the most affected because of the temporary housing they had to live in. Even the incidences of crime violence increased, whereas the main casualties were mostly women.
Mass extinction and loss of phylogenetic have led to the loss of fisheries and a decrease in the insect population. With the collapse of the number of insects, food productivity has also gone down due to lack of crop yielding.
Besides production, a high concentration of carbon dioxide in the air improves the production of carbohydrates, starch, and sugars, which found in consumed crops. But it is also notable that increased carbon dioxide depletes calcium, copper, iron, magnesium, and zinc in many plants.
Higher carbon concentration reduces water demand making fewer nutrients to sieve through plant roots, which can cause obesity.
Weather patterns also affect vulnerable groups such as pregnant women, children, the elderly, and the disabled. These groups of people find it difficult to change and adapt to various climate changes.
The current and emerging policies regarding climate change have not come up with a proper mechanism to protect its citizens from the effects of climate change. Humans across the globe have to continue wrestling with the conditions brought by these adverse climate changes. Climate impacts will continue to be a great threat to humankind.
