Question

causes of global warming in 200 to 400 words

Answer 1

HEY MATE HERE IS YOUR ANSWER ♥♥♥♥

Global warming is caused by human activities such as burning fossil fuels, and farming.

Burning fossil fuels

When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.

Australians are big producers of CO2 pollution compared to the rest of the world. Our level of CO2 pollution per person is nearly double the average of other developed nations and more than four times the world average.

Electricity generation is the main cause of carbon pollution in Australia as 73% of our electricity comes from burning coal and 13% from burning gas. The remaining 14% comes from renewable energy sources such as hydro, solar and wind, which do not emit carbon. 

Reducing the amount of electricity generated from coal and gas, and increasing the amount of electricity from clean, renewable energy sources like solar and wind, means less carbon pollution is emitted. This is one of the main ways we can address global warming.

Deforestation

Plants play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it. Forests and bushland act as carbon sinks and are a valuable means of keeping global warming to 1.5°C.

But humans clear vast areas of vegetation around the world for farming, urban and infrastructure development or to sell tree products such as timber and palm oil. When vegetation is removed or burnt, the stored carbon is released back into the atmosphere as CO2, contributing to global warming. Up to one-fifth of global greenhouse gas pollution comes from deforestation and forest degradation.

Preventing deforestation as well as planting trees, through reforestation and afforestation, are important actions in the fight against global warming.

Farming

Animals, livestock like sheep and cattle, produce methane, a greenhouse gas. When livestockgrazed at a large scale, as in Australia, the amount of methane produced is a big contributor to global warming. 

Some that farmers use also release nitrous oxide, which is another greenhouse gas.

Australian farming contributes 16% of our total greenhouse gas emissions. Using different and different stock feeds can help to reduce farming's contribution to climate change.

hi friend
here is your answer

There are many causes of the global warming which affects human lives and health in many aspects. The main cause of global warming is the human beings careless activities. Ever increasing human population are demanding more resources to live easy and healthy life such as land to live and crop cultivation, technological growth for comfort and deal with increasing temperature of atmosphere, etc. Fossil fuels burning for many reasons are highly responsible to increase global warming. People are realizing well the increase in environmental warmth however never mind their activities which are stimulating the global warming to increase. Continuously they are wasting natural resources and polluting the air, water and soil.


Increasing inventions of the technologies such as refrigerator, AC, car/automobiles, electric machines, oven, microwave, washing machine, etc because of the increasing need of human beings for technologies in order to make their life, easy and luxurious. All such resources ultimately contribute to the global warming. Burning fossil fuels in the automobiles emits various green house gases which get collected in the atmosphere and force it to heat. Increasing need of land by human being results deforestation which contributes to increase in CO2 and decrease in oxygen. It affects the human health, life style, calls diseases, calls natural disasters like hurricanes, heat waves, drought, climate change and so many.Increase in environmental temperature and climate change has become very clear over the last 50 years because of increasing level of greenhouse gases concentration (like water vapour, CO2, methane, ozone, sulphur and nitrogen gases, etc ) in the atmosphere. Such as greenhouse gases contribute to increase in the greenhouse effect. The major cause of increasing greenhouse gas in the environment is burning of fossil fuels which emit carbon dioxide and heat the atmosphere. Such green house gases have capacity to absorb more heat from sun, heat from electricity used by human beings in many ways which in turn warm the whole atmosphere of this planet. The effects caused by the greenhouse gases (water vapour, CO2, methane, ozone, nitrous oxide, hydro fluorocarbons, sulphur hexafluoride, per fluorocarbons, chlorofluorocarbons, etc) are called as the green house effect.

Heating of the environment increases atmospheric temperature (by 3° to 5° C by the year 2100), increases sea level (by 25 meter by year 2100) and heat, melts glaciers, increases health disorders, changes climate, changes weather, increases annual power of hurricanes, calls natural disasters (floods, heat waves, droughts, tornadoes), lowers down amount and quality of agricultural yields, enhances glacial retreat, reduces summer stream flows, extinctions of various important plants and animals species and so many. There are some other dangerous effects of the global warming which continuously affects the lives of human beings, plants and animals. Global warming needs to be solved urgently by the active effort of each and every human being living on this planet.Increase in environmental temperature and climate change has become very clear over the last 50 years because of increasing level of greenhouse gases concentration (like water vapour, CO2, methane, ozone, sulphur and nitrogen gases, etc ) in the atmosphere.
