Increasing World Temperature Can Expose Billions of People to Diseases

Climate change and global warming have been the subject of frantic discussions all over the world in recent years. More and more studies have been surfacing that show that until these two are not controlled immediately, our planet will be harder to live on in the future. The Earth's temperature is important to be maintained in such a way that no living organisms will be affected. It greatly impacts on the survival of both humans and animals as well as the growth of plants. 

As what the World Wildlife Fund said, our climate is determined by several factors, such as patterns of temperature, atmospheric pressure, wind, humidity, and rain. With the changes in our natural environment, the food we consume and the water we drink will be affected. Unfortunately, there has been a significant increase in the world's temperature in recent years. An article by the National Geographic reported that our planet's average temperature has risen to more than one degree Fahrenheit or 0.9 degree Celsius over the past century. 

The rise of world temperature and other negative impacts caused by global warming and climate change can massively damage our ecosystem. They can disrupt habitats and affect our industries. At the same time, they can also cause diseases that can be very harmful to humans. 

A Deeper Look at Global Warming

The world is getting warmer and warmer every year due to several reasons like natural occurrences and, the most obvious, human activities. Scientists from NASA’s Goddard Institute for Space Studies (GISS) reported that there has been an increase of 0.8 degrees Celsius in the average global temperature on Earth since 1880. This can still rise, according to an article by Reuters. The article added that global temperatures can rise to about three to five degrees Celsius in this century. 

In an interview, Secretary-General Petteri Taalas of the World Meteorological Organization (WMO) stated that the world's temperature may increase further if humans exploit all known fossil fuel resources. “Greenhouse gas concentrations are once again at record levels, and if the current trend continues, we may see temperature increases 3 to 5 degrees C by the end of the century," he said. 

It is important that people should be mindful in helping to limit the rise in global temperatures. This is to prevent the negative impacts caused by global warming, such as the rise in sea levels, more extreme weather conditions, and the loss of plant and animal species. WWF discussed that rising sea levels is due to the melting glaciers and ice caps all over the world, especially in the Arctic region. This is because it increases the volume of water in our oceans.

Additionally, global warming leads to more extreme weather events. These weather conditions include cyclones, bushfires, droughts, hurricanes, floods, and many more. These can get more intense as a result of global warming. An article by the Earth Observatory mentioned the significant changes in the temperature in several countries since the year 2000. For instance, there has been a 50% increase in land temperature in the United States, three to four times in the Arctic and the Antarctic Peninsula, and two to three times in Eurasia. 


The Rise of World Temperature Can Cause New Diseases

Global warming will not only disrupt our planet in all aspects but affect human beings as well. A recent study conducted by researchers from the Georgetown University Medical Center discovered that the rise of world temperature can expose billions of people to disease-carrying mosquitoes by the end of the century. 

According to an article by the Science Daily, this discovery can affect even the countries where climates are not suited for mosquitoes. This is because these insects carry viruses that are notorious for explosive outbreaks. As global change biologist Colin J. Carlson, Ph.D., and co-author of the study said, the most comprehensive and largest threat to global health security is climate change. "Mosquitoes are only a part of the challenge, but after the Zika outbreak in Brazil in 2015, we're especially worried about what comes next," he said. 

The World Health Organization reported that mosquitoes are one of the deadliest animals in the world. They carry diseases that cause millions of deaths every year. Aedes aegypti and Aedes albopictus, the two most common disease-carrying mosquitoes, are particularly dangerous because they can carry several diseases. These diseases include the Zika virus, chikungunya, and dengue. The scientists added that there can also be other emerging diseases because of these insects, bringing a threat for the next 50 years. 

According to Sadie J. Ryan, lead author of the research, these diseases are starting to show up in several tropical countries where climates suit mosquitoes like Florida. There are also some areas that will be affected by dengue although they have a climate not suitable for these insects, such as North America, Europe, and high elevations in the tropics.
