What is climate change? A change in global or regional climate patterns, a change which was noticed during the mid 20th century due to excessive use of fossil fuels. Some reason why climate changes: Natural causes: • Continental drift- led to the change in the physical features of land, its position and a change in ocean currents. • Volcanoes- the ash emitted during the eruptions cool the global temperature, in their absence the temperature has been on the rise. • Ocean currents have been known to change direction or slow down. The heat that escapes from the oceans is in the form of water vapor, the most abundant greenhouse gas on Earth. Yet, water vapor also contributes to the formation of clouds and has a net cooling effect. Human causes: …show more content…
By cutting trees there won’t be enough oxygen available in the atmosphere and there will be high amount of CO2 available which will heat the earth up. What are the effects of climate change? A Climate effects in a very vigorous way. • Due to the change in climate, natural disasters take place taking away lives of the people. For example, The Nepal earthquake which took place on 25th April, 2015 which killed over 8000 people and injured more than 21000 people. • The change in climate also affect the ocean currents and heat up the land under the water causing tsunamis. For example, The Japan earthquake and tsunami which took place on march 11, 2011. • Excessive heat emitted in the atmosphere causes excessive evaporation leading to sudden rains. • High temperature causes the glaciers to melt which raises the sea level on earth which will cause having more frequent flooding and very low-lying land could get submerged completely, It will also affect the food as too much water flowing into the agricultural lands will spoil the …show more content…
Is the present climate change a natural phenomenon or human induced? The present climate change is mostly human induced; the increase in CO2 is mainly because of human activities. Activities like changes in land use pattern, deforestation, land clearing, agriculture, and other activities that have all led to a rise in the emission of carbon dioxide. Methane is also another important greenhouse gas in the atmosphere is the resultant of human activities. It is infused in the atmosphere due to- • Domestication of animals • Fields being flooded during sowing & reaping of rice/paddy—mostly contributed by countries in Asia as rice is grown here and is the staple food of people • It is also emitted when waste dumps are burnt which in turn releases CO2 • Methane is also released while drilling & coal mining or due to accidents that lead to leaking gas pipelines Use of pesticides & other fertilizers infuse nitrogen oxide into the water bodies acidifying the water which kills the plants and aquatic animals living in
producer of methane gas is the world), as well as the huge amount of land used to
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
Climate change is difficult to express directly, for knowledge of climate change generally falls under the classification of “weather.” However geologists have known since the mid-nineteenth century that local, and global climate undergoes change throug...
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
The largest source of methane emissions in the United States are landfills. Landfill gas, which is
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. (EPA Environmental Protection Agency, 2014)
Climate change has had many impacts all over the world and evidence of it is very apparent. One example that climate change has impacted the earth is the rising sea levels. Since planet earth is slowly getting warmer by greenhouse gasses, the glaciers and ice sheets around the world are melting, which is adding more water to the oceans. Within the last century, the global water levels have risen by nearly 7 inches. In a quote from “A Student 's Guide” they say,
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential
...est human source of CO2 emissions is the burning of fossil fuels, such as coal, oil, and gas. Further, human contributions of deforestation is a devastating two pronged effect in that when humans burn forests it produces increases of CO2 emissions and the removal of trees and plants reduces CO2 absorption by removing the photosynthesis cycle that absorbs CO2 and generates oxygen. The photosynthesis process accounts for half of the carbon extracted from the atmosphere (Global Climate Change and Energy Carbon Dioxide Sources, 2015). As evidenced, both fossil fuel combustion and deforestation equally contribute as the largest impact to CO emissions; resulting of an imbalance of the carbon cycle. The imbalance of the carbon cycle influences global warming that will result in increase in temperatures, rise in sea levels, severe storms, and animal and plant extinction.
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted
Climate change impacts the basic resources needed by nations to continue and for humans to survive and continue on with their lives. For this reason, civil unrest occurs and wars happen. Militant groups and radicals such as ISIS control and secure their access to what is left of these resources like water so as for people to join their cause. There are also uprisings all over the world where protesters demand food due to starvation from lack of food which resulted from drought and food price increases which affects the global market significantly. Moreover, poverty is also a result of

Natural disasters is one of the more deadly effects of climate change due to its random and violent behaviors. An example of a natural disaster that are more likely caused by climate change is hurricanes. These tropical cyclones
The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth.
