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.
Approximately 50 billion tons of greenhouse gases are emitted annually. This includes carbon dioxide, methane, nitrous oxide, and fluorinated gases. These emissions are primarily from human activities such as burning fossil fuels, deforestation, and industrial processes.
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.
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,
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.

Which greenhouse gas is the most powerful absorber of radiation emitted by Earth?
Carbon dioxide (CO2) is the most powerful absorber of radiation emitted by Earth among greenhouse gases. It contributes significantly to the greenhouse effect and plays a key role in regulating Earth's temperature.
How do green house gases determine the temperature of the lower atmosphere?
Greenhouse gases absorb and re-emit infrared radiation emitted by the Earth's surface, trapping heat in the lower atmosphere. This process, known as the greenhouse effect, results in an overall warming of the lower atmosphere. Increased concentrations of greenhouse gases lead to more heat being trapped, causing the Earth's temperature to rise.
What type of radiation is in the atmosphere due to greenhouse gases?
Infrared radiation is the type of radiation trapped in the atmosphere due to greenhouse gases. This radiation is emitted by the Earth's surface and is absorbed and re-radiated by greenhouse gases, such as carbon dioxide and water vapor, leading to the warming of the Earth's surface.
Which are the two major greenhouse gases?
Carbon dioxide is emitted by burning fossil fuels (coal, oil and natural gas).Methane is emitted by bad farming practices in cattle and rice farming.
How is the greenhouse effect caused on a molecular level?
The greenhouse effect occurs when certain gases in Earth's atmosphere, such as carbon dioxide and methane, trap heat from the sun. These gases absorb infrared radiation emitted by Earth's surface, preventing some of the heat from escaping into space. This results in a warming effect on the planet.
Is it possible to capture or divert greenhouse gases emitted from the burning of fossil fuels?
Yes, it is possible to capture greenhouse gases emitted from the burning of fossil fuels through technologies like carbon capture and storage (CCS). These technologies can capture carbon dioxide before it is released into the atmosphere and store it underground or use it for other applications. However, the effectiveness and scalability of these technologies are still being developed and implemented.
What natural greenhouses gases are associated with the greenhouses effect?
The main natural greenhouse gases associated with the greenhouse effect are water vapor, carbon dioxide, methane, and nitrous oxide. These gases trap heat in the Earth's atmosphere, leading to a warming effect on the planet.
How do people know that greenhouse gases are being emitted?
Using carbon dioxide as an example: * Measurement of atmospheric carbon dioxide show a progressive increase * Calculations from the amount of fuel consumed indicate that CO2 is being generated, the gas is not being contained, removed or colected. It must therefore be being emitted
The two principle absorbers of radiation emitted by earth's surface are carbon doxide and?
water vapor. These gases are greenhouse gases that absorb and re-emit the infrared radiation emitted by the Earth's surface, trapping heat in the atmosphere and leading to the greenhouse effect.
How much greenhouse gas emitted by bicycles?
Bicycles do not emit greenhouse gases when in use as they are human-powered. However, greenhouse gases are emitted during the manufacturing process of bicycles and their components. By comparison, the emissions associated with the production of bicycles are significantly lower than those of motorized vehicles.
Which greenhouse gas is the most powerful absorber of radiation emitted by Earth?
Carbon dioxide (CO2) is the most powerful absorber of radiation emitted by Earth among greenhouse gases. It contributes significantly to the greenhouse effect and plays a key role in regulating Earth's temperature.
How are ozone and greenhouse gases alike and how are they different?
Ozone is also a greenhouse gas by nature. The only difference being that greenhouse gases do not absorb UV rays.
What are some of the vital gases being emitted into the atmosphere?
Dcafscd
How much greenhouse gases does a television emit in a year?
The amount of greenhouse gases emitted by a television in a year would depend on factors such as its energy efficiency, usage patterns, and the source of electricity used to power it. Overall, televisions are not major contributors to greenhouse gas emissions compared to other household appliances.
Which gases in the atmosphere trap the sun's warmth?
Greenhouse gases such as carbon dioxide (CO2), methane (CH4), and water vapor trap the sun's warmth in the Earth's atmosphere, leading to the greenhouse effect. These gases absorb infrared radiation emitted by the Earth's surface and re-radiate it back, helping to keep the planet warm.
What country produces the most carbon?
China is now the biggest emitter. The United States is the country that has emitted the most greenhouse gases.
How do green house gases determine the temperature of the lower atmosphere?
Greenhouse gases absorb and re-emit infrared radiation emitted by the Earth's surface, trapping heat in the lower atmosphere. This process, known as the greenhouse effect, results in an overall warming of the lower atmosphere. Increased concentrations of greenhouse gases lead to more heat being trapped, causing the Earth's temperature to rise.
