 GLOBAL WARMING

- The planet's overall temperature is experiencing long-term warming, a phenomenon known as global warming. While this warming trend has been ongoing for a considerable period, its pace has notably accelerated in the past century due to the increased burning of fossil fuels. As the human population has grown, so has the consumption of fossil fuels, including coal, oil, and natural gas. The combustion of these fuels leads to the "greenhouse effect" in Earth's atmosphere.


The greenhouse effect occurs when the sun's rays penetrate the atmosphere, but the heat reflected off the surface is unable to escape back into space. Gases emitted from the burning of fossil fuels trap the heat within the atmosphere. These gases, such as carbon dioxide, chlorofluorocarbons, water vapor, methane, and nitrous oxide, contribute to the excess heat in the atmosphere, resulting in a gradual increase in the average global temperature over time, commonly referred to as global warming.


Global warming has also given rise to another concern known as climate change. Although these terms are sometimes used interchangeably, they have distinct meanings. Climate change encompasses alterations in weather patterns and growing seasons worldwide. It also encompasses the rise in sea levels caused by the expansion of warmer seas and the melting of ice sheets and glaciers. Global warming serves as the driving force behind climate change, which poses a significant threat to life on Earth through widespread flooding and extreme weather events. Scientists are actively studying global warming and its impact on our planet.

- DEFINATION

Global warming refers to the progressive rise in the Earth's temperature primarily caused by the greenhouse effect, which is triggered by elevated levels of carbon dioxide, CFCs, and other harmful pollutants.

- EFFECT

Temperature Rise

The rise in the earth's temperature caused by global warming has been remarkable. Since 1880, there has been an approximate increase of 1 degree Celsius in the earth's temperature. Consequently, this has resulted in the accelerated melting of glaciers, leading to a rise in sea levels. The implications of this phenomenon could be catastrophic for coastal regions.


Ecosystem Threats

Global warming has had a detrimental impact on coral reefs, posing a significant threat to both plant and animal life. The elevated global temperatures have exacerbated the vulnerability of coral reefs, further endangering their existence.


Alterations in Climate

Global warming has brought about significant changes in climatic conditions worldwide. Some regions experience severe droughts, while others suffer from devastating floods. This imbalance in climate patterns is a direct consequence of global warming.


Disease Spread

The patterns of heat and humidity have been altered due to global warming, resulting in the displacement of disease-carrying mosquitoes. This shift has facilitated the spread of diseases carried by these mosquitoes.


Increased Mortality Rates

The rise in floods, tsunamis, and other natural disasters often leads to a higher average death toll. Additionally, these events can also contribute to the spread of diseases, further endangering human life.


Loss of Natural Habitats

The global climate shift has caused the loss of habitats for numerous plant and animal species. As a result, these animals are forced to migrate from their natural habitats, and many of them face the risk of extinction. This represents another significant impact of global warming on biodiversity.

- CAUSE OF GLOBAL WARMING

These are 2 type

1 . Man-made Causes of Global Warming

2. Natural Causes of Global Warming


1. MAN MADE CAUSE OF GLOBAL WARMING

- Deforestation is the process of clearing or removing trees from a forested area. This activity has significant consequences for the environment. Plants play a crucial role in maintaining the environmental balance by absorbing carbon dioxide and releasing oxygen, which is essential for human and animal life. However, due to deforestation, forests are being depleted for various purposes, both domestic and commercial. This has resulted in an environmental imbalance, leading to the phenomenon of global warming.


The use of vehicles, even for short distances, contributes to the emission of harmful gases into the atmosphere. Vehicles burn fossil fuels, such as gasoline or diesel, which release a large amount of carbon dioxide and other toxins. These emissions contribute to the greenhouse effect, causing an increase in temperature.


Another factor contributing to global warming is the excessive use of air conditioners and refrigerators, which release chlorofluorocarbons (CFCs) into the environment. CFCs have a detrimental effect on the ozone layer, which protects the Earth's surface from harmful ultraviolet rays emitted by the sun. The depletion of the ozone layer allows more ultraviolet rays to reach the Earth's surface, resulting in an increase in temperature.


Industrial development has also played a significant role in the rise of global temperatures. The emissions from factories, including greenhouse gases and other pollutants, contribute to the overall increase in temperature.


According to a report by the Intergovernmental Panel for Climate Change in 2013, the global temperature has increased by 0.9 degrees Celsius between 1880 and 2012. This increase is even higher, at 1.1 degrees Celsius, when compared to the pre-industrial mean temperature.


Agricultural activities also contribute to global warming. Various farming practices produce carbon dioxide and methane gas, which are greenhouse gases that contribute to the warming of the Earth's atmosphere.


Lastly, overpopulation has a direct impact on global warming. As the population increases, more people are breathing and exhaling carbon dioxide, which is the primary gas responsible for global warming. This leads to an increase in the concentration of carbon dioxide in the atmosphere, further exacerbating the issue.


In conclusion, deforestation, vehicle emissions, the use of CFCs, industrial development, agricultural activities, and overpopulation are all contributing factors to global warming. It is crucial to address these issues and adopt sustainable practices to mitigate the effects of climate change.

2. NATURAL CAUSE OF GLOBAL WARMING

Prompt 1: Rewrite the text about volcanoes.


Volcanoes play a significant role in contributing to global warming. The expulsion of ash and smoke into the atmosphere during volcanic eruptions has a direct impact on the climate.


Prompt 2: Rewrite the text about water vapor.


Water vapor, a type of greenhouse gas, contributes to global warming. As the Earth's temperature rises, more water evaporates from bodies of water and remains in the atmosphere, further exacerbating the issue.


Prompt 3: Rewrite the text about melting permafrost.


Permafrost, which refers to frozen soil containing trapped environmental gases beneath the Earth's surface, is predominantly found in glaciers. As the permafrost thaws, it releases these gases into the atmosphere, ultimately leading to an increase in the Earth's temperature.


Prompt 4: Rewrite the text about forest blazes.


Forest blazes, also known as forest fires, release a substantial amount of carbon-containing smoke. These gases are emitted into the atmosphere, contributing to the rise in the Earth's temperature and subsequently causing global warming.


Q. Control of global warming

Mitigating global warming requires effective control over the release of carbon dioxide and other greenhouse gases into the atmosphere. One approach is to establish a substantial carbon price, which incentivizes industries to reduce their emissions. Additionally, increasing the production of biofuels from organic waste can contribute to lowering greenhouse gas emissions. Embracing renewable energy sources such as solar and wind power is another crucial step towards combating global warming. Furthermore, protecting forests and enhancing energy efficiency, along with improving vehicle fuel economy, are essential measures in our collective efforts to address this pressing issue.

ENVIRONMENTAL EFFECTS

- Climate change is altering the availability of water, resulting in increased scarcity in various regions. The phenomenon of global warming further intensifies water shortages in areas that are already experiencing water stress. Consequently, this poses a heightened threat of agricultural droughts impacting crops and ecological droughts heightening the susceptibility of ecosystems.

Global warming mitigation measures.

- Save energy at home

- Walk, cycle, or take public transport

- Reduce, reuse, repair & recycle

- Change your home's source of energy

- Switch to an electric vehicle
