An Overview of Climate Change
Climate change can be defined as the fluctuation in long-term weather patterns (DS Foundation). One form of climate change is global warming, which is the progressive warming of the planet (Habitable Planet). Since the industrial revolution, the average global temperature has increased by approximately 0.8o celsius (Habitable Planet, McKibben, 2012). These long-term changes are attributed to anthropogenic sources such as fossil fuel combustion for industrial activities (Habitable Planet).
Fossil fuel combustion (among other forms of emissions) result in increased concentrations of atmospheric greenhouse gasses (Habitable Planet). These greenhouse gases (GHG), such as carbon dioxide (CO2) and methane (CH4), …show more content…

The agriculture sector largely grows temperature sensitive and rainfed plants such as maize, wheat, and sorghum, illustrating the region’s high sensitivity to changes in long term weather patterns (Turn Down). A large proportion of the population in this region continues to depend on agriculture for their main source of nutrition and income (Turn Down). The effects of climate change and global warming on Africa are already visible (Turn Down). In 2011, a drought in the Horn of Africa affected 13 million people and led to significant malnutrition (Turn …show more content…

Should action to mitigate climate change be taken if some areas of the world are benefited? Models have predicted eastern Africa to be wetter, and a decrease in the risk of drought has been predicted (Turn Down). For a region of the world that has felt the negative impacts of drought before in 2011, why should they strive to work against climate change (Turn Down)? The reality is that increased precipitation will likely be in concentrated bursts in certain times of the year, which is not as beneficial to agriculture as temporally distributed rainfall (Turn Down). In addition, these predictions are relatively uncertain (Turn Down). Finally, scientists have predicted droughts over southern and central Africa as a result of climate change. Overall, the increased rainfall in eastern Africa is not very certain, not necessarily beneficial, and is not without increased risk of droughts in other regions of

Greenhouse gases are those that absorb and emit infrared radiation in the atmosphere. The most abundant greenhouse gases in Earth 's atmosphere are: Carbon dioxide, Methane, Nitrous oxide ,Ozone ,Chlorofluorocarbons (CFCs). Human activities also contribute to climate change by the amounts of greenhouse gases, aerosols (small particles). The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas in the atmosphere.

Changes And Continuities In Sub Saharan Africa From 1500 To 1750

532 Words | 3 Pages

From 1500 to 1750, there were changes and continuities on the ways Sub-Saharan Africa participated in interregional trade. The major turning point of Sub-Saharan Africa’s participation is the start the slave trade in West Africa. This event impacted the New World, Europe and SE Asia because Europe profited from the exploitation of Africans to the New World, Southeast Asia experienced a decline in population because of the start of the slave trade between Southern Africa and Indonesia, and the New World became more profitable as plantations where slaves worked grew. The overall continuity of Sub-Saharan Africa’s participation in trade is the European dominance in the region because of the Age of Exploration led by the Portuguese and Spanish.

Global Warming: What Can Licking County Do Essay

1215 Words | 5 Pages

Global warming is a rise in the Earth’s global temperature, whether through natural or man-made circumstances. Factors causing global warming through natural means would be volcanic emissions and increased solar activity. The major issue with global warming is the progress of humankind. Increases in industrialization and deforestation, which release the greenhouse gas, carbon dioxide (CO2), act as a blanket in the atmosphere. CO2 with the combination of water vapor, trap heat from the sun between the atmosphere and the earth’s surface, causing a rise in temperature (Haldar, 2011).

Recently, my focus has shifted to agricultural and resource economics, with a particular interest in Africa. Some economists, such as Jeffrey Sachs, have argued that Africa suffers from a so-called “resource curse,” which is exacerbated by climate change resulting from unsustainable use and regulation of resources. More specifically, my home country, Malawi, suffers from food insecurity, a challenge to attaining the first, millennium development goal. This problem is mainly linked to the lack of effective economic policies, which enhance the resilience of vulnerable communities to climate

Persuasive Essay Coal

806 Words | 4 Pages

The reason why methane gasses are so potent to the planet is because of the structure of the compound, it traps more heat in the atmosphere than carbon dioxide. Consequently, that makes methane gasses 80 times more harmful than carbon dioxide for 20 years after its release into the atmosphere. This article shows methane gasses are incredibly dangerous to the planet and the environment. Since coal, oil, and gas are some of the main reasons for methane emissions, it would be smart to decrease the usage of those materials in order to protect the environment. By decreasing coal production and usage, methane emissions could be decreased which could further decrease methane emissions and greenhouse gasses.

Greenhouse gases act like a blanket, and trap heat in the atmosphere. Carbon dioxide is a greenhouse gas (Climate change, 2015). In the past 20 years, humans have increased atmospheric carbon dioxide by more than 30%, by burning fossil-fuels and cutting down forests. The Earth has not experienced carbon dioxide levels this high for the past several million years (Carbon Levels, 2015). Researchers are learning that future climate change will depend on carbon levels in the land, atmosphere, and sea, and how these levels respond to human disturbance (Carbon in the Economy, 2015).

Climate Change is a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Global warming is an an increase in the overall temperature of the earth’s atmosphere caused by greenhouse gases. Greenhouse gas is a gas that contributes to the greenhouse effect by absorbing infrared radiation, e.g., carbon dioxide and chlorofluorocarbons. Pollution is the presence in or introduction into the environment of a substance or thing that has harmful or poisonous

Have you noticed that over the past few centuries, the environment has changed quite a bit? Some people argue that it hasn’t changed at all but what about the lakes that are now all dried up? What about the increase in temperature in general? People often confuse climate change for global warming but while they are similar in some sense, they are also very different. Global warming is only when the earth is getting warmer and climate change is when the earth is getting warmer or colder at surprising rates.

An Essay: Why Climate Change Is Not Real?

708 Words | 3 Pages

Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own conclusions on how are humans responsible for climate change and whether or not it is a real thing. Some people think and guarantee that climate change is real and it is happening at least in part because of human activity.
