What are three main reasons for climate change?

Answer 1

1. Global warming is causing climate change.
2. Burning fossil fuels (coal, oil and natural gas) is causing global warming.
3. Cutting down forests is causing global warming.

Answer 2

1. Deforestation.
2. Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide, a greenhouse gas.
3. Poor agricultural practices in pig and cattle farming, as well as rice paddy fields, all of which release methane, another powerful greenhouse gas.

There is really only one cause of global warming, the greenhouse gas effect, which prevents the sun's infrared radiation being reflected back into space. In the past this has been good for us, keeping the earth at a constant temperature suitable for human life. We now have an accelerated greenhouse effect, which is being caused by:

Burning fossil fuels: Now, since humankind started building factories, power stations and vehicles, the amount of carbon dioxide being put into the atmosphere is far more than before. So the greenhouse blanket is better at holding in the heat, and the earth is warming up.

Deforestation: The other reason for the increased carbon dioxide is that we have cut down the great forests of the world. Trees are a natural sink for carbon dioxide, soaking it up. Now it has nowhere else to go but up.

A:

1. Methane (NH4) released in the wetlands of the arctic and the tundra regions cause the temperature of the earth to increase and thus causes global warming.
2. Greenhouse gases (gases which trap the sun's heat inside them and do not allow it to escape, thus it increases the temperature) released by the factories, automobiles and other human activities add to the greenhouse effect in the atmosphere.
3. Increase in population (overpopulation) has further increased the rate of global warming as we all use more and more electricity, usually produced by burning fossil fuels. The level of carbon dioxide has increased further due to deforestation (cutting down of forests). plants take in CO2 and give out O2, but deforestation means that the level of CO2 in the atmosphere will increase and thus result in global warming.
