What Is The Source Of Carbon Dioxide – Water vapor, carbon dioxide, methane and nitrous oxide are the main greenhouse gases in the atmosphere that trap heat near the Earth’s surface. If they weren’t present, the oceans would freeze and the planet would be uninhabitable. But greenhouse gases are so good at trapping heat from the Sun that if their levels increase just a little, Earth’s temperature will also increase, causing significant negative impacts on life on Earth. . Various natural processes, such as photosynthesis and respiration to produce carbon dioxide, or methane production by microorganisms in wetlands, control the natural presence of these gases. This greenhouse is in the atmosphere. However, human activity, especially since the industrial era, has rapidly increased the amount of certain greenhouse gases in the atmosphere, causing the Earth system to warm at unprecedented rates. These man-made greenhouse gases can remain in the atmosphere for years, decades or even longer (depending on the type of gas) after emission.

Monitoring atmospheric concentrations and basal fluxes between the Earth’s surface and the atmosphere provides insight into the human impact on these rising greenhouse gas concentrations.

Mainly due to burning fossil fuels for energy production, transportation or industrial activities and eliminating natural carbon sinks through deforestation, which can also lead to direct carbon emissions into the atmosphere atmosphere due to forest burning or a later release through wood burning, for example. There is also significant natural CO uptake and release

Faster ‘sinks’, such as chemical reactions in the atmosphere and bacteria in the soil, can remove it.

Science Speaks: Carbon Capture

O) is largely due to emissions from microbial nitrification and denitrification processes, which occur naturally in soils, freshwater systems, and oceans. However, human activities, such as fertilizer use in agriculture, contribute significantly to emissions, nearly equal to the total emissions from natural sources. Main sink for N

The Copernicus Atmospheric Monitoring Service (CAMS) and C3S monitor and record carbon dioxide and methane levels in the atmosphere using instruments on the ground, in the air and on satellites. Using atmospheric models to link observations to the underlying fluxes between the Earth’s surface and the atmosphere, CAMS also monitors these fluxes, helping to better understand the carbon and methane cycles. Satellite-based observations form the backbone of the services, but CAMS and C3S also use in situ data, collected by any equipment not on board the satellite.

Satellite observations and in situ observations are complementary. Satellites measure carbon dioxide and methane throughout the entire depth of the atmosphere and globally; however, their data is currently less accurate than in situ measurements. In situ instruments sample the lower parts of the atmosphere with great precision, but most are found in easily accessible areas, and more developed countries often have better in situ coverage.

A combination of observations and computer models is used to improve estimates of the fluxes of carbon dioxide, methane and nitrous oxide between the Earth’s surface and the atmosphere. Observed concentrations, using both in situ and satellite observations, were compared to model-simulated concentrations, and surface fluxes in the model were gradually adjusted until the difference approached zero. This process is called atmospheric inversion and is used by CAMS to update global estimates of annual net flux. CAMS provides maps that show how, on average, the land surface is emitting greenhouse gases into the atmosphere and where they are being removed, as well as time series across the globe or large regions that show how this pattern is changing. how over time. Although current CAMS atmospheric inversions do not distinguish between anthropogenic and natural emissions and removals, they contribute to advancing our knowledge of the carbon cycle.

Carbon Emissions Rebound To Near Pre Pandemic Levels

Most of the world’s greenhouse gas emissions come from a small number of countries. China, the United States and the countries that make up the European Union are the three largest emitters on an absolute basis. Greenhouse gas emissions per capita are highest in the United States and Russia.

Note: Carbon dioxide emissions have increased rapidly over the past 70 years. However, they are predicted to remain stable, albeit at very high levels, in the coming decades. Emission reductions in developed economies are expected to offset growth in carbon dioxide emissions in developing countries.

Not shown in this chart, other greenhouse gases (such as methane, nitrous oxide, and fluoride gas) are expected to increase by 30% over the next three decades.

Greenhouse Gases, Facts And Information

Greenhouse gas intensity is a measure of emissions relative to GDP. This rate is highest in Russia and China, while the United States is lower than the world average.

Globally, the main sources of greenhouse gas emissions are electricity and heat (31%), agriculture (11%), transportation (15%), forestry (6%), and manufacturing (12%). . Energy production of all types accounts for 72% of total emissions.

CO2 accounts for about 76% of total greenhouse gas emissions. Methane, mainly from agriculture, contributes 16% of greenhouse gas emissions, and nitrous oxide, mainly from industry and agriculture, contributes 6% to global emissions. All figures here are expressed in CO2 equivalents. Global carbon dioxide emissions are rising again as power plants and industry burn more coal and natural gas, narrowing the remaining window of opportunity to limit warming to 1.5 degrees Celsius.

According to new research published November 4, industrial carbon dioxide emissions have returned to near pre-pandemic levels. Rising coal and natural gas consumption by power plants and industry is driving the recovery – especially in China – even as transportation emissions remain depressed and The use of renewable energy increases.

– up 4.9% compared to 2020 – similar to the increase in emissions after the 2008 global financial crisis.

“We were expecting this recovery as the world economy returned to near normal levels. Park your car for a year and it’s still the same polluting car when you start it up again. Likewise, as economic activity returns, so do emissions,” said Rob Jackson, professor of Earth system science at Stanford University and president of the Global Carbon Project, an academic consortium provides annual emissions estimates, said.

The estimates come amid a major climate summit known as COP26 in Glasgow, Scotland, where countries that signed the 2015 Paris Climate Agreement are discussing efforts to reach the goal. of the agreement is to keep global warming below 2 degrees Celsius above pre-industrial levels. ,
