Global Warming

Global Warming

Global warming can be referred as the constant increase in the Earth’s average temperature since 1950. It also denotes to climate change that results in rise in the average temperature. Global warming is a grave problem and it is not an only issue but several environmental concerns. The causes of global warming are classified into two classes such as “human influences” and “natural” causes.

Natural Causes of Global Warming

The temperature of the Earth has been changing continuously for periods. The global warming takes place due to sun’s natural rotation that increases the strength of sunlight and moves closer to the earth. Greenhouse gases, sulphur dioxide and carbon monoxide, is another cause of global warming. These gases trap the rays of solar heats and stop it from evading from the earth’s surface. This results in rise in the earth temperature. Moreover, volcanic eruptions also cause global warming. For example, a single volcanic eruption discharges a significant amount of CO2 and ash to the environment. Once CO2 rises, the temperature of the earth increases and greenhouse traps the solar emissions.

In last, methane, a greenhouse gas, is another main cause of global warming. It traps the heat 20 times more effectively in the environment as compared to CO2. Commonly it can be released from different sources such as from landfill, cattle, petroleum systems, natural gas, industrial waste process, mobile explosion or coal mining,.

Human Influences on Global Warming

Among several factors, the influence of human is considered very serious due to unfriendly human activities. Human factors causing globing are more severe than natural. Among unfriendly human activities, burning of fossil fuel, industrial production, cattle rearing, mining and deforestation are most prominent.Industrial have been making use of fossil fuels for the generation of power machines which makes almost everything of human use. For example, the process of manufacturing mobile phone involves machines which run through fossil fuels. In addition, these machineries release carbon di oxide.   Moreover, deforestation is yet another most important cause of global warming. Deforestation is one of the unfriendly human activity through which they cut down trees to produce wood, papers and other wood materials. Carbon dioxide concentrates more in the atmosphere due to deforestation because trees have potential of absorbing CO2 from atmosphere.



Warmer temperatures

In 2012, the Sahel countries in North Africa suffered a food crisis that affected about 18 million people due to the scarcity of rain. The effects of drought are not new in this area, which is experiencing periodic recurrent droughts but the intensity and frequency of these droughts, which have increased during the last decade due to the increase in temperatures in the planet.

More intense storms

The fact that temperatures are higher makes the rains less frequent, but more intense; Therefore, the level of floods and their severity will also increase.

Disease propagation

A temperature change of several degrees can make the temperate zone more welcoming to the spread of certain diseases. In this way, cases of Chagas disease, dengue or other diseases that are forgotten in developed countries and in areas that have traditionally been colder can begin to occur. This also affects developing countries. A case study in Ethiopia conducted by scientists at the University of Denver (UD) and Michigan (UM) concluded that a one-degree increase in ambient temperature results in the development of 3 million more cases of malaria in Ethiopia in patients less than 15 years of age.

Stronger heat waves

The global warming of the planet produced by the accelerated burning of exhaustible fossil fuels has been very intense in the North Pole. This makes the North Pole much hotter today than it was fifty years ago. The health and even the lives of thousands of people may be at risk due to the increase in heat waves, both in frequency and intensity.

More dangerous hurricanes

Rising sea temperatures cause hurricanes to become more violent because a hurricane is the means that the planet has to distribute the excess heat from warm to cooler areas. And at more temperature, more hurricanes, with all the problems they entail: destruction of cities, crops, dismantling of all systems, diseases.

Change of ecosystems

Higher temperatures, less precipitation, droughts and floods make the climate adapt to this new climate and, therefore, there are changes in the duration of the seasons, appear patterns more typical of monsoon climates.

More Expensive Foods

Climate change threatens the production of basic foods such as wheat, which means that hundreds of thousands of people whose lives depend on their crops are at risk of losing everything. And not only that: if crops are scarce, prices soar. This affects us all, but in the least developed countries, with very high poverty rates, the consequences can be devastating.


The crux of the matter is that global warming is a serious problem which is mainly caused due to unfriendly human activities. Its impacts are severe for the survival of human being on the earth. It does not only affect the human lifestyle but also impart a significant impact on the economy. Human must take individual as well as collective measures to stop unfriendly activities such as deforestation, burning of fossil fuel, or burning garbage. In addition, government must also reduce deforestation because it is the main factor of increasing earth temperature.   Recycling is another way to reducing global warming and its impacts. The process of recycling can reduce trash by re-using bottles, plastic bags, glass or papers. By encouraging environment friendly activities, the impact of global warming can be reduced.
