Climate Change

Climate change is basically known as a change in the structure of the climate, which has been running for many decades and centuries. Various natural factors that change the nature of the Earth’s atmosphere are also known as ecosystems which are pressurized on the environment.These special external systems, which put pressure on the environment, may be natural, such as variation in Earth’s orbit, inequality in solar radiation, volcanic eruptions, plate tectonics, etc. and various human activities such as greenhouse gas, carbon emissions etc.

Various activities of human beings, such as deforestation, excessive use of land have also been included in this particular external system to bring about change in the environment, the formation of different conditions has been made naturally as it involves ocean activity. It includes-environmental variability and the presence of life on Earth.

Climate change refers to the change in the environmental conditions of the earth. This happens due to many internal and external factors. The climatic change has become a global concern over the last few decades. Besides, these climatic changes affect life on the earth in various ways. These climatic changes are having various impacts on the ecosystem and ecology. Due to these changes, a number of species of plants and animals have gone extinct.

When Did it Start?

The climate started changing a long time ago due to human activities but we came to know about it in the last century. During the last century, we started noticing the climatic change and its effect on human life. We started researching on climate change and came to know that the earth temperature is rising due to a phenomenon called the greenhouse effect. The warming up of earth surface causes many ozone depletion, affect our agriculture, water supply, transportation, and several other problems.

Reason Of Climate Change

Although there are hundreds of reason for the climatic change we are only going to discuss the natural and manmade (human) reasons.

Natural Reasons These include volcanic eruption, solar radiation, tectonic plate movement, orbital variations. Due to these activities, the geographical condition of an area become quite harmful for life to survive. Also, these activities raise the temperature of the earth to a great extent causing an imbalance in nature.Human ReasonsMan due to his need and greed has done many activities that not only harm the environment but himself too. Many plant and animal species go extinct due to human activity. Human activities that harm the climate include deforestation, using fossil fuel, industrial waste, a different type of pollution and many more. All these things damage the climate and ecosystem very badly. And many species of animals and birds got extinct or on a verge of extinction due to hunting.Effects Of Climatic ChangeThese climatic changes have a negative impact on the environment. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. Apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. And there will be a heavy loss to the environment.What will be Future?If we do not do anything and things continue to go on like right now then a day in future will come when humans will become extinct from the surface of the earth. But instead of neglecting these problems we start acting on then we can save the earth and our future.

Although humans mistake has caused great damage to the climate and ecosystem. But, it is not late to start again and try to undo what we have done until now to damage the environment. And if every human start contributing to the environment then we can be sure of our existence in the future.

GLOBAL WARMING

“Global warming is a term that refers to a steady rise in the average temperature of the Earth’s atmosphere and oceans, a phenomenon that is thought to be irreversibly altering the Earth’s climate.”
The increase in the average global temperature of the Earth is used to measure global warming. Some sections of the Earth may become colder as our average global temperature rises, while others may become warmer—hence the concept of average global temperature. Atmospheric heating and agitation induced by greenhouse gases increase the unpredictability of weather and climate, as well as the severity, scale, and frequency of storms, droughts, wildfires, and severe temperatures. The gases in the atmosphere that absorb and release heat radiation include water vapour, carbon dioxide, methane, nitrous oxide, and ozone. Increasing or lowering the amount of greenhouse gases in the atmosphere causes the sun’s heat to be trapped or released more.

Causes of global warming:

Fossil fuel combustion: CO2 pollution is released into the atmosphere when fossil fuels such as coal and gas are burned to generate energy or power our cars. Burning coal, oil, and gas produces carbon dioxide, the most major greenhouse gas in the atmosphere, as well as nitrous oxide, which is certainly the initial source of global warming.

Deforestation: Forest exploitation is a significant contributor to global warming. By absorbing CO2 from the atmosphere, trees aid in climate regulation. When trees are cut down, the carbon contained in them is released into the atmosphere, negating the positive effect. Forests and wilderness serve as carbon sinks, helping to keep global warming below 1.5 degrees Celsius. Humans, on the other hand, clear enormous swaths of land for farming, urban and infrastructural development, and the sale of tree products like lumber and palm oil all over the world. When vegetation is cut down or burned, the stored carbon is released as CO2, contributing to global warming.

Farming & Agriculture: Methane is a greenhouse gas produced by livestock, such as sheep and cattle. The amount of methane created by livestock grazing on a vast scale, such as in Australia, contributes significantly to global warming. Intensive farming, which includes not just ever-increasing livestock but also plant protection products and fertilizers, is another contributor to global warming. When cattle and sheep digest their food, they produce enormous volumes of methane, whereas fertilizers emit nitrous oxide.

Mining: The mining and metallurgical industries are vital to modern living. Metals and minerals are the raw materials that are used to create, transport, and manufacture items. This market accounts for 5% of all greenhouse gas emissions from extraction to distribution. Decarbonization initiatives across industries may result in significant shifts in commodity demand for the mining industry. Governments, investors, and society will put pressure on the mining sector, which is responsible for 4 to 7% of global greenhouse gas (GHG) emissions, to reduce emissions.

Eruption of a Volcano: When volcanoes erupt, they release large amounts of carbon dioxide. Volcanoes have a minor impact on global warming, and eruptions result in short-term global cooling because ash in the air reflects more solar energy. Volcanic eruptions release gases and dust particles into the atmosphere, which have an impact on the climate. The majority of the particles ejected by volcanoes cool the earth by shielding it from the sun’s rays. Depending on the features of the eruption, the cooling impact can continue anywhere from months to years.
