How much greenhouse gases are being emitted yearly?

Answer 1

Carbon Dioxide emissions:

Human respiration (breathing): 2 BMT (Billion Metric Tons)

Domesticated animals respiration: 6 BMT

Wild Animal (excluding Insects) respiration: 4 BMT

Burning of fossil fuels in Internal Combustion Engines (cars, etc): 16 BMT

Burning of fossil fuels to Generate Electricity: 9 BMT

Other Human-Industrial CO2 emissions: 1 BMT

********************************************************

Insect Respiration: 48 BMT

That's right, insects produce nearly twice as much carbon dioxide as all humans industrial emissions.

By the way, I don't have the figures handy, but all of the above is a DROP IN THE BUCKET compared to what the OCEANS emit. But as much as they emit, they absorb even more.

Also, contrary to popular belief, rain forests do not CONSUME carbon dioxide, at least not in net terms. Yes, they consume quite a bit of CO2, but if the trees are not harvested, they will die and rot, releasing all of their stored carbon back into the atmosphere to combine with oxygen and form CO2.

In terms of REAL CO2 generation. Our Oceans emit between 90 and 107 GTonnes of CO2 annually. This represents 97% of all CO2 produced. This number is nothing though, in comparison to the annual volume of the real greenhouse gas. Water Vapor, which represents up to 80% of all forcing and 99% of all gas emitted annually.

The most recent figures are that the burning of fossil fuels, mainly for electricity generation, smelting and transport, emits over 30 billion tonnes of carbon dioxide each year, and rising. This is "new" carbon dioxide, which actually adds to the atmospheric concentration of carbon dioxide, unlike almost all other sources which are part of the natural carbon cycle and do not add anything to the atmospheric concentration of carbon dioxide.

Answer 2

The emission of carbon dioxide by living things is part of the natural cycle and does not lead to an increase in greenhouse gases. There is a very smll increase from volcanic eruptions, but otherwise, the increase comes from human activities.

The most important contribution to higher levels of greenhouse gases is the burning of fossil fuels, which now adds over 30 billion tonnes of carbon dioxide to the atmosphere every year. Next comes deforestation, which currently adds less than 10 billion tonnes of carbon dioxide to the atmosphere every year, then cement manufacture. Around 30 per cent of these amounts are absorbed by the oceans.

Answer 3

There are about 35 billion tonnes of CO2 (a major GHG) emitted each year. There are about 7 billion people on Earth. On average each person would emit about 5 tonnes a year. However the emissions are not evenly divided and the average rate of emission in the developed countries is much higher tan the average,

Answer 4

Every year humans add over 30 billion tons of carbon dioxide in the atmosphere and that number seems to be increasing as our demand for fossil fuels increases.

Answer 5

It is depends on person. Normally human emit only co2.

Answer 6

Three main gases:

1. Carbon dioxide (CO2)
2. Methane (CH4)
3. Water vapour (H2O)
