Introduction

All species on the planet and several ecological processes rely on optimum temperature for survival. Conversely, optimum temperature allows people to perform their work effectively and increases diversity. The planet’s temperature has always played an essential role in proving the optimum temperature for survival and ecological processes. However, there is an alarming trend worldwide of increasing the earth’s surface temperature. Scientists have been measuring global temperature for a long time and conclusively agree that the temperature is gradually rising on earth (Lindsey & Dahlman, 2022). Ideally, scientists often record the temperature of specific locations worldwide and then convert them to anomalies temperature from readings of absolute temperature. In this case, anomalies temperature is “the difference between the observed temperature and the long-term average temperature for each location and date. Multiple” (Lindsey & Dahlman, 2022). Comparing the temperature trends from 1990 to 2020, there is a gradual increase in temperature, and each month in the year 2021 had a temperature more than the average regardless of the cooling effects of La Nina (Lindsey & Dahlman, 2022). Scientists usually measure the planet’s temperature to predict how things will get in the future. Students need to get such climate updates to plan for themselves, especially after knowing the temperature trends.  Knowing how to conduct oneself using simple steps of reducing, reusing, and recycling are essential in ensuring sustainability on earth. Misinformation and ignorance are some of the factors that make people engage in activities that compromise the survivability of humans. Tackling the increase in temperature issues from an individual level is necessary. Eventually, students will become well informed to make rational decisions in the future regarding the planet’s wellness. This paper focuses on how the earth is increasing temperature gradually.

Scientific Process

Since time immemorial, several ecological factors have always played a key role when it comes to the maintenance of the earth’s temperature. For instance, the world is usually protected from the sun’s intense radiation by the ozone layer, many kilometers away from the planet’s surface. The ozone layer contains three atoms of oxygen combined, absorbing UVB and other harmful radiation from reaching the earth (Center for Climate and Energy Solutions, 2022). Consequently, the ozone layer also absorbs infrared radiation that I produced from the planet. Altogether, it can be argued that the ozone layer helps balance the earth’s temperature. However, the efficacy of the ozone layer has been dramatically undermined by greenhouse gases. According to research, natural greenhouse gases include water vapor, nitrous oxide, methane, and carbon dioxide, while synthetic greenhouse gases include fluorinated gases. Since the industrial period, there have been many advances on the planet by humans, such as the production of cars, the manufacturing of refrigerators, the rearing of more livestock for meat production, and deforestation so that more land can be used for commercial and agricultural processes (Center for Climate and Energy Solutions, 2022). All the mentioned human activities lead to the production of greenhouse gases. For example, cars, burning fossils, some automobiles, and deforestation increase carbon dioxide production. Livestock rearing leads to the production of methane. Old appliances such as refrigerators often produce fluorinated gases, while some industries emit nitrous oxide as a by-product. Research indicates that “globally, the primary sources of greenhouse gas emissions are electricity and heat (31%), agriculture (11%), transportation (15%), forestry (6%), and manufacturing (12%)” (Center for Climate and Energy Solutions, 2022). The production of greenhouse gases leads to them accumulating in the atmosphere. Since there is no way to regulate them in the atmosphere, the accumulation of GHG increases the planet’s temperature (Center for Climate and Energy Solutions, 2022). When greenhouse gases accumulate in the atmosphere, some gases (chlorine and fluorine derivatives) end up destroying the ozone layer, thus undermining the efficacy of the ozone layer. Conversely, the accumulation of GHGs forms a blanket layer in the atmosphere beneath the ozone layer. As mentioned, the earth absorbs radiation from the sun, and when enough radiation has been absorbed, the planet emits some of the heat back into the atmosphere. The radiated heat is usually in the form of infrared. Unfortunately, when infrared heat encounters the blanket layer, it is generally reflected on earth. As the population on the planet increases, more human-related activities that produce greenhouse gases will increase. With more GHG in the atmosphere, the infrared from the planet will be radiated back to the earth, which will lead to the greenhouse effect. It can be argued that the reflected heat back to the world (greenhouse effect) traps heat, so the planet becomes warmer. An increase in the GHGs leads to more warming effects, which explains why the planet’s temperature is gradually increasing.

Consequences

Unfortunately, the increase in the earth’s temperature has led to several adverse effects on humans. The increased temperature on the planet means more evaporation will occur in water bodies, and there will be more precipitation. Increased precipitation leads to incidences of flooding, which hurts agriculture. For example, according to a post in the Guardian, the farmers and natives who planted their crops in Australia along River Lachlan counted their losses when floods destroyed nearly all their crops (May 2022). In Kenya, a report by the Red Cross indicated that over 21000 acres of planted food crops had been destroyed by flood, leading to a hunger crisis in some parts of the region (OCHA, 2022).  Several countries worldwide have experienced food crises where food shortage is attributed to flooding. Flooding also leads to infectious, especially waterborne diseases, such as cholera, along coastal regions. In some places, flooding may result in contamination of drinking water when it links with sewage and the likelihood of aquatic pathogens outbreak in the recreational water. There are several instances whereby masses have been infected by Cholera after water used by them gets contaminated with the causative agent of the disease. Again, Incidences of flooding also lead to loss of lives and destruction of properties. Moreover, an increase in temperature increases incidences of heat-related diseases and complications such as pre-term birth, renal failure, asthma, and underlying cardiovascular conditions. Additionally, an increase in temperature creates a breeding spot for mosquitoes in some tropical and subtropical regions, leading to increased malaria incidents, a significant public health concern (Wang et al., 2022). Increased temperatures also lead to incidences of wildfires. Australia has experienced numerous massive bushfires caused by an increase in temperature. For instance, more than 33 people have lost their lives, “including four firefighters – and more than 11 million hectares (110,000 sq km or 27.2 million acres) of bush, forest, and parks across Australia have burned” (BBC News, 2022). As the temperature increases gradually, humans will have more severe repercussions. The negative impacts may reach a point whereby the sustainability of humans o the planet is undermined. Altogether, it can be argued that food crises, destruction of properties, wildfires, and incidents of diseases and complications are some of the significant effects of an increase in temperature on humans.

Conclusion

In conclusion, changes in weather patterns contribute to the overall climate of a specific place. Scientists often collect, measure, and analyze data to provide credible weather patterns that are helpful to people. Unfortunately, data provided by scientists collectively show that the planet’s temperature increases gradually, whereby each month gets warmer. Research has indicated that the increase in temperature is due to the greenhouse effect. As mentioned, industrialization led to humans engaging in activities that produced significant amounts of greenhouse gases in the atmosphere. The accumulation of greenhouse gases leads to heat-trapping on the planet, eventually leading to the warming effect on the earth. The warming effect is often known as the greenhouse effect. Consequently, it has been discussed that the warming impact leads to adverse effects on the planet, especially on humans. For example, flooding in some places has led to food shortages, loss of lives, the spread of waterborne diseases, and the destruction of properties. Moreover, there have been increased incidences of heat-related diseases and complications. In some countries, such as Australia, there have been several cases of wildfires that have killed people and destroyed productive lands. Based on the event recorded, it can be predicted that more issues of the exact nature will be experienced if nothing changes. The world population is growing, and the amount of GHGs in the atmosphere is also increasing due to human-related behavior. As mentioned, an increase in temperature may interfere with the standard temperature balance mechanism in the future, so the sustainability of living organisms becomes jeopardized. The research provides valuable information to the students on how they should become advocates of green solutions. For instance, practicing reuse, recycling, and reducing can benefit everyone on the planet owing to the increase in temperature issues. I recommend that everyone begins making a change at the individual level to ensure sustainability on the earth and that the planet becomes livable for future generations. Working together on this will also ensure that the levels of GHGs produced in the atmosphere reduce substantially.
