Teachers often ask their students to write essays on global warming. We collect the most interesting examples which can help prepare your custom version.
1. Did People Cause Global Climate Change? [Sample 1]
Even the various theories proposed by scientists on what might happen in the future based on past data seem to be contradictory. Some theorize that global warming might lead to melting snow caps, which will result in sea levels rise in all the oceans. Others theorize that global warming can trigger another ice age. Still, people say that these things are part of a repetitive cycle and that past data shows rises and drops in global temperature over thousands of years.
There are others who even go to the extent of saying that global warming is nothing but a scam. They say that global warming proponents can earn a lot of money through several methods by playing on people’s fears. In their opinion, it is a carefully orchestrated plan to mint money from nothing but a myth.
2. Environment assignment essay on: Population & climate change [Sample 2]
Question about the beneficial impacts of climate change
What are the adverse and the beneficial impacts of climate change on the population as envisaged by the Inter-Governmental Panel on Climate Change (IPCC)? How is climate change going to differently affect two population groups, one living in a poor, warm and low-lying country with high population density and another living in a rich, a high altitude and cold country?
Some of the researches as well as studies have been used in order to understand the mechanism along with the complexities of the population. The entire research has been established in order to see the adverse & the beneficial impact of climate change on population growth (Dalton, Jiang, Shonali, & O’Neill, 2007). The adverse, as well as the beneficial impact, has been discussed as under. The intergovernmental panel on climate change (IPCC) has seen, strong evidence regarding the global warming affecting human activities. Such type of changes would lead to a change within the environmental hazards affecting human health (Clark & Deurloo, 2006). Some of the adverse effects which might be encountered by the increased population would be stress to food production, ozone depletion, infectious diseases, hazards, bio-diversity, etc. Based upon the World Health Organization (WHO) it has been seen that 160,000 deaths have taken place since 1950 due to the change in the climate. According to the Research at the Hoover Institution, it has been seen that global warming would lead to a decrease within the rate of morality in the US (Jiang & Hardee, 2011). University Assignment Help Australia-based upon the UK programs, it has been estimated that approximately 36% reduction within the carbon dioxide emissions would lead to benefits to the increased population. Health benefits could be seen with respect to the various improvements within the air quality (Woodward, 2005). This would take into consideration an overall exposure to the particles, poisoning of the carbon monoxide, etc. Some of the more benefits which would be seen with respect climatic change would be in regards to the replacement of the cookstoves which would be acted quite substantial (Bindoff, et al, 2007). Assignment Writing Tutor AustraliaClimate change has affected the population living in a poor, warm and low-lying country with high population density has been discussed as under. Main adverse effects have been seen in regards to the same. A report on global human impact was published in Global Humanitarian in the year 2009 (Kent & Haub, 2005). According to WHO it has been estimated that approximately 99% of the causalities have risen in such places due to change in the climates. Buy Assignment AustraliaClimate change has affected the population living in a rich, a high altitude and cold country has been discussed as under. It has been seen that countries such as US, UK have varied effects over the change in the climates. The rich sectors are quite sensitive towards the change in the climate.
3. Climate Change Essay [Sample 3]
During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be done about it. For example, carbon dioxide can stay in the atmosphere for nearly a century, so Earth will continue to warm in the future.
Global warming has really taken effect in the world over the last century. It is the unusually rapid increase in the Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming is due to the enhancing of greenhouse gases emission and build-up in the Earth’s environment. The gases that have an influence on the atmosphere are water vapor, carbon dioxide, dinitrogen-oxide, and methane. Almost 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. In the other 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet. This absorption and radiation of heat by the atmosphere is beneficial for life on Earth. Today, the atmosphere contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. By increasing the concentration of greenhouse gases, we are making Earth’s atmosphere a more efficient greenhouse. Climate has cooled and warmed throughout the Earth history for various reasons. Rapid warming like we see today is unusual in the history of our planet. Some of the factors that have an effect on climate, like volcanic eruptions and changes in the amount of solar energy, are natural. Climate can change if there is a change in the amount of solar energy that gets to the Earth. Volcano eruptions can really affect climate because when it erupts it spews out more than just lava and ash. Volcanoes release tiny particles made of sulfur dioxide into the atmosphere. These particles get into the stratosphere and reflect solar radiation back out to space. Snow and ice also have a great effect on the climate. When snow and ice melt Earth’s climate warms, less energy is reflected and this causes even more warming. There are many different ways that plants, animals, and other life on our planet can affect climate. Some can produce greenhouse gases that trap heat and aid global warming through the greenhouse effect. Carbon dioxide is taken out of the atmosphere by plants as they make their food by photosynthesis. During the night, plants release some carbon dioxide back into the atmosphere. Methane is made while farm animals, such as cattle and sheep digest their food. Cars and trucks can effect the climate by releasing carbon dioxide when fossil fuels are burned to power them. When wildfires occur, carbon dioxide is released into the atmosphere. However, if a forest of similar size grows again, about the same amount of carbon that was added to the atmosphere during the fire will be removed. Some effects that scientists have predicted in the past would result when the global change was occurring: loss of sea ice, accelerated sea-level rise, and more intense heat waves. Scientists have confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC) stated that the extent climate change effects on individual regions will vary over time and with ability of different societal and environmental systems mitigate or adapt to change (The Intergovernmental Panel on Climate Change). This has been the warmest decade since 1880. According to the National Oceanic and Atmospheric Administration, 2010 and 2005 has been the warmest years on record. The earth could warm by an additional 7.2 degrees Fahrenheit during the 21st century if we fail to reduce emissions from burning fossil fuels (The National Oceanic and Atmospheric Administration). The rising of temperature will have great effects on the earth’s climate patterns and on all living things. Industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide from 280 parts per million to 379 parts per million in the last 150 years (The Intergovernmental Panel on Climate Change).
In conclusion, we need to take part and try to stop global warming and other effects on climate change. If the earth’s temperatures continue to rise in the future, living things on earth would become extinct due to the high temperatures. If humans contribute to control global warming, this world would be cooler and the high temperatures we currently have would decrease. If everybody as one take a stand and try to end most of the climate changes that are occurring, this world would be a safer place to live on.
Climate Change Essay [Sample 4]
External forcing mechanisms can either be natural such as the variation in the Earth’s orbit, variation in solar radiation, volcanic eruptions, plate tectonics, etc or can be caused due to human activities such as greenhouse gases, carbon emission, etc. Internal forcing mechanisms, on the other hand, are the natural processes that occur within the climate system. These include the ocean-atmosphere variability as well as the presence of life on the earth.
Global Warming and Climate Change
Climate change is having a negative impact on the forests, wildlife, water systems as well as the polar region on the Earth. A number of species of plants and animals have gone extinct due to the changes in the climate on the Earth and several others have been affected adversely.
Human activities such as deforestation, use of land and use of methods that lead to the increase in carbon in the atmosphere have been a major cause of climate change in the recent past. It is important to keep a check on such activities in order to control climatic changes and ensure environmental harmony.
Climate Change Essay Variant 2
As the name suggests, climate change is a change in the climatic conditions on the Earth. Several factors contribute towards this change since centuries. However, the more recent ones that are mainly a result of human activities are having a negative repercussion on the atmosphere.
Researchers continually observe the pattern to understand the past, present as well as the future climatic conditions. A record of the climate has been accumulated and is updated regularly based on the geological evidences to study the changes occurred. These evidences include the records of flora and fauna, glacial and periglacial processes, records of sea levels, borehole temperature profiles and sediment layers among other things.
Here is a closer look at the causes and effects of climate change:
Causes of Climate Change
The factors that contribute towards climate change are:
The energy emitted by the Sun that reaches the Earth and is carried further to different parts of the planet by winds and ocean currents is one of the main reasons for climatic change.
The new-age technology is adding to the emission of carbon on the planet which in turn is having a negative impact on the climate.
Apart from this, the orbital variations, plate tectonics and volcanic eruptions also cause changes in the climate.
Effects of Climate Change
Impact on Forests and Wildlife
A number of species of plants and animals have gone extinct due to the change in the climatic conditions and many others are on the verge of going extinct. With the mass extinction of trees in certain regions, many forests are also diminishing.
Impact on Water
Changes in the climatic conditions are also having a negative impact on the water system. It has resulted in the melting of glaciers and erratic rainfall patterns that in turn are leading to environmental imbalance.
It is important to take the climate change issue seriously and control human activities that are contributing towards this change.
Reasons of Global Warming [Sample 5]
Climate change is a global environmental issue, which concerns the whole humanity. Consequences of the global warming will influence life on Earth in a very strong way, so that every single person should be familiar to this problem. The reasons that underlie global warming are divided into two main categories: natural and human.
Let’s start this global warming essay from the natural reasons. Actually, climate on Earth has been gradually changing due to the changes of the intensity of the sunlight. Greenhouse gases are another important factor. There are two main greenhouse gases: carbon dioxide and sulfur dioxide that are generated in nature (as well as by human activity). These gases literally catch solar heat and do not let it inside or outside. This way, heat stays in the atmosphere and the temperature of Earth surface increases.
All of us know that human activity causes growth of amount of greenhouse gases in the environment but one volcanic eruption has much more influence than humanity ever. Extremely big amount of carbon dioxide and ash is released during the volcanic eruption.
The last gas, which is important to the climate change, is methane. We use it in order to get heat but methane is produced in great amounts in nature. Although these amounts are not so big as the amounts of carbon dioxide, methane catches solar heat 20 times better than carbon dioxide. Cattle are a great natural source of methane. Human sources are: landfill, petroleum systems, coal mining etc.
The ways humanity influences climate are not so diverse because all of them are related to industry. Industrialization is closely bound with usage of fossil fuel. Firing fossil fuel causes release of carbon dioxide into the atmosphere. Usage of cars has the same consequence.
Mining and cattle rearing increases the concentration of methane in the atmosphere. Especially manure is a great source of methane.
The last reason is deforestation. Plants absorb carbon dioxide but when humanity destroys forests, the amount of plants decreases and more carbon dioxide stays in the atmosphere.
Geologists were the first to understand that the climate is changing. Soon, climate scientists themselves began to study temperature dynamics and found out that it is important for everything: for the environment, for agriculture, for the economy. Well, OK, what does it have to do with ordinary people? What can we influence?
we are nothing alone. But if the climate changes, we will have to adapt to it.
