How do humans affect the atmosphere?

Answer 1

We are affecting things, by the non-stop addition of CO2 to Our Paper Thin Atmosphere - in addition to a surprisingly large number of even more potent greenhouse gases, in a thoroughly negative fashion.

Answer 2

We humans burn fossil fuels (coal, oil and natural gas) which releases carbon dioxide into the atmosphere. Energy from the Sun warms the Earth's surface via short-wave radiation. Some of this energy is reflected back as long-wave radiation.

Carbon dioxide, water vapour and other gases prevent this long-wave solar radiation escaping from the atmosphere. This is called the greenhouse effect, and it is thought to be the primary cause of Global Warming.

Hope this helps. :)

Answer 3

We add carbon, that is, extra carbon, to the atmosphere, mostly by the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide.

We also emit carbon, that is, recycled carbon (part of the carbon cycle), in our bodily waste materials, and we give off quite a bit by breathing. We also add carbon by producing and depending on very large herds of livestock.

Answer 4

1. The human activity of deforestation has removed the trees that used to absorb carbon dioxide (CO2) from the atmosphere.
2. The human activity of burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity releases additional CO2 into the atmosphere.

So the levels are rising.

Answer 5

By the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).

Answer 6

by creating carbon monoxide

Answer 7

Burning fossil fuels.
