Global Warming In Africa

Africa is a continent that suffers most under climate change. Increase in temperature triggers a “sharp decline in yields in tropical regions,” an estimated 5-10% in Africa, associated with an increase in malnutrition, malnutrition, and malaria-related deaths. Global warming in Africa is very high.

The impact of climate change in Africa has led to widespread changes in the continent and the people who live there. Many changes in the intensity of weather and storms have already experienced. Extreme flooding has plagued many parts of Africa. Not long ago, floods in Uganda, 400,000 people left homeless. This is the result of extreme rainfall that caused severe flooding in the area. The researchers say that this flow is nothing compared to what people can experience, if global warming continues. These floods not only leave people homeless, they undermine food production. Since the plants are cleared away, many people have starved to death. Move flooding of the wildlife in the area as well. As flood waters rose wild animals have no place to retreat too. Animals that survive are more difficult to find food to survive.

Effects of climate change in Africa have caused the drought to be severe. Intense storms began to emerge as the very dry soil is blown by strong winds. Drought makes it very difficult for people in Africa to grow crops, reducing their food supply. These intensity winner severe sandstorms and began performing more often.

Global warming is causing many health hazards of the population in Africa. Cases of heatstroke and other heat-related illnesses are becoming more frequent. Several diseases have spread rapidly. Dehydration and hunger becomes even more frequent. The struggle to survive in Africa is becoming increasingly difficult.

Global warming is a big problem for all peoples of the planet. But Africa seems to be hardest hit by the effects of global warming. As temperatures continue to rise, the promise of a better future does not seem positive. Scientist says that Africa is experiencing complications will only increase if global warming continues.

How does Global Warming Happen

 The basic question which arises in the mind of the common man is how does global warming happen? As you all know that the atmosphere of the Earth is composed of oxygen, nitrogen, and a dozen other gases. All these serve to capture a certain amount of heat and keep the soil warm. The sunlight striking the Earth and is absorbed as heat. The heat radiates into the air. The air molecules absorb and release heat. Some molecules are heavier than others radiate more heat to the earth. Without these molecules from specialty gases, Earth would be frozen at about 14 degrees below zero.

The absorption and reflection of heat is known as the greenhouse effect. Some gases like carbon dioxide, methane and nitrous oxide are harm full to our nature. They form a blanket around the atmosphere and do not allow the heat to go outside and make the earth temperature very high. This is known as global warming. The main cause of global warming is these green house gases. As you all know that carbon dioxide is very essential for the nature and plants use sunlight and carbon dioxide to prepare sugar and oxygen. But having CO2 in large quantity will also create problem, all that extra carbon dioxide gets into the atmosphere where it blocks the release of heat leaving the earth.

The question how does global warming happen has other major reason human activities. Humans cause global warming to an increase in side effects on the environment. People do not use energy efficiently. Using light standard bulbs and equipment, which consume more energy and electricity. This allows a large amount of carbon dioxide emissions. Cutting down trees for human use, such as building houses, roads and many other purposes has decreased the number of trees. Trees absorb a lot of carbon dioxide; deforestation has led to increase the volume and thereby causing global warming.

Methane Global Warming

Gases causing the green house effect are carbon dioxide, water vapors and nitrous oxide. Green house effect is the major cause of global warming. Besides these gases methane is also responsible for the global warming. Methane can severe the global warming and can lead to rise in temperature, floods, rise in sea level, hurricanes and mankind will come to an end. The harmful effect of methane on global warming is very high and measure should be taken to decrease the methane global warming.

Methane is considered as very powerful gas than Co2 and concentration of methane in atmosphere is increasing day by day. The methane has the capacity to stay in the atmosphere for 7 years, trapping heat and returns to earth. Infrared radiation reflected from the country of methane, which increases global warming. However, the effect of methane is less than the CO2. Even if CO2 can affect the atmosphere for 100 years, the effect of methane is 7 years. It should be remembered, that its effect is 21 times the CO2 impact.

Coal mining, animal husbandry, sewage sludge, manure, agricultural waste, landfills, decomposition of sludge in the Oceans Rivers is sources of methane. Burning oil and natural gas are also the source of methane. To reduce the effect of methane global warming, stop the activities that produce methane. Using the fuels, which are not derived from crude oil, should be encouraged. Methane should be burned, particularly in landfills for the production of CO2. Meat and livestock should be adjusted to reduce methane.

Electrolysis, the use of metal catalysts that can be done to minimize the production of methane. These are some of the ways by which the effect of methane global warming can be reduced. Methane is a greenhouse gas emission that can have serious consequences for the Earth’s atmosphere and must be minimized to reduce the effects of global warming.

Ozone Layer And Global Warming

Ozone layer and global warming are co related to each other. Ozone layer is the layer lies within the stratosphere and is made of a specialized form of oxygen. The ozone layer is located 10-20 miles above the earth surface. This layer traps the harmful effects of ultraviolet radiations from the sun and therefore plays a crucial role in life on Earth. But there are series are of chemical reactions taking place which are threat to the ozone layer. Chemicals such as chlorofluorocarbons, methyl bromide, etc., are released into the atmosphere due to various anthropogenic causes, including the use of refrigerants (CFC free), and the use of insecticides.  The molecules of these chemicals tend to break down ozone molecules, thus hindering their ability to trap the UV radiations. With the depletion of ozone layer there is decrease in temperature.

Ozone layer and global warming are different phenomenon but have links between them. Global warming is due to the green house gases, which forms the thick blanket around the surface of the atmosphere and traps the sun’s radiation which warms the surface of the earth. Due to heat is not reflected back and is trapped in the troposphere. As temperature of the stratosphere decrease, the ozone molecules in this layer are vulnerable to destruction by harmful emissions. So global warming not directly but play a significant role in the depletion of the ozone layer.

Depletion of the ozone layer driven by the drop in temperature in the stratosphere can be termed as another dangerous effect of global warming on Earth. Although the Montreal Protocol has played an important role in the fight against harmful emissions that cause ozone to deplete in the two decades of it, are on the threshold of a new crisis of the layer of ozone, this time conducted by one of the most dangerous environmental problems facing the planet – global warming. So ozone layer and global warming should be taken care simultaneously.
