What is the Adaptation Gap Report 2021

The Adaptation Gap Report (AGR) is an annual UNEP flagship report of the UNEP.  The report’s primary goal is to inform the state and developments in climate adaptation at both global and regional levels.  The report’s main goal is to update the compact between the UNFCCC Members States and the wider UNFCCC Constituent, an organisation of Constituent on the state and direction of climate adaptation at the global as well as regional levels. The main greenhouse gases found in the atmosphere of Earth include water vapour, carbon dioxide and nitrous oxide, methane and ozone.  In the absence of greenhouse gases, the temperature of the Earth’s surface would be a little less than 18 deg (0 deg) instead of the current average of 15 degrees Celsius according to the greenhouse gas emissions.

Greenhouse gas

Gases that hold heat in the atmosphere are called greenhouse gases.  This section contains information on the emission and removal of major greenhouse gas emissions in the atmosphere.  Take a look at Climate Change Indicators for more details about the other climate-related factors like black carbon.

Carbon dioxide (CO2): 

Carbon dioxide gets into the atmosphere by burning fossil fuels (coal, natural gas, coal, and oil) and solid waste, trees, various biological materials, and chemicals, e.g., cement manufacturing.  Carbon dioxide is eliminated from the air when plants absorb it in the biogeochemical carbon cycle.

Methane (CH4): 

Methane is released during natural gas, coal, and oil production and transportation.  Methane emissions are also a result of livestock and other agricultural practices, land use, and the decomposition of organic wastes in municipal waste landfills.

Nitrous oxide (N2o):

Nitrous oxide is released in land use, agriculture, industrial activists, combustion of fossil fuels, solid waste, and wastewater treatment.

Fluorinated gases: 

According to the Adaptation, perfluorocarbons and hydrofluoric compounds, sulphur hexafluoride, and nitrogen trifluoride are synthetic powerful greenhouse gases released from commercial, household, industrial, and household processes gap reports.  The fluorinated gases are generally smaller than other greenhouse gases; however, they are potent greenhouse gases.  Intensifying impacts of Global warming potentials (GWPs) typically range from thousands to tens of thousands; they are sometimes referred to as high GWP gases because they trap substantially more heat than CO2 for a given amount of mass. 

Greenhouse emission is the positive inward flow of energy to the Earth’s atmosphere, resulting in an abnormally high temperature and global warming due to a rise in the Earth’s average surface temperature caused by increased volumes of Carbon dioxide, nitrous oxide, and other greenhouse gases.

The danger to life on the planet is global warming:

The greatest danger to life on this planet is global warming, also known as the greenhouse effect (greenhouse gas emission, or GHG).  The greenhouse effect results from gases in the Earth’s atmosphere that allow sunlight to enter but prevent most heat from exiting.  For this reason, the atmosphere remains warm, even though the Earth has night and day cycles with temperatures ranging from freezing to boiling.

Natural phenomenon:

The greenhouse gas emissions occur naturally as a phenomenon due to the atmosphere around the Earth’s absorption of heat energy.  It causes the Earth’s surface temperature to rise, allowing chemical processes like decay to proceed at an increased rate, releasing more carbon dioxide.  Greenhouse gases cannot be stored and accumulate in the upper layers of the atmosphere.  They have been found near other planetary bodies as well.

The magnitude of the effect:

• While the magnitude of this effect is small, the importance of this phenomenon is high.  Carbon dioxide and water vapour are the main greenhouse gases that cause the Earth’s surface to warm up
• Carbon dioxide, which contributes to global warming, is emitted from burning fuel.  As a greenhouse gas, carbon dioxide traps heat and warms the atmosphere.  The greenhouse gas emission can be linked directly or indirectly to human activities, including methane, carbon dioxide, the ozone, and nitrous oxide.  Greenhouse gas emissions are a major source of air pollution in the United States
• The upper atmosphere is so thin that it can be considered a vacuum,  only some 500 miles deep.  Gravity and inertia also contribute to this low pressure near the top of the atmosphere.  The temperature does not vary much from the surface to the upper edge of the troposphere.  About 24 km (15 mi.) above sea level, the atmosphere thickens considerably and cools off dramatically!  A layer of ozone protects us by absorbing harmful ultraviolet radiation that would otherwise damage our skin and eyes

Conclusion

Greenhouse gas emission is the main cause of global warming, submerging our Earth in unbearable heat; it further causes unpredictable changes in weather patterns.  Greenhouse emission is mainly caused due to release of greenhouse gases like carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons from industries and automobiles.  Carbon dioxide is produced in coal, oil, and natural gas combustion and during deforestation.  Reducing the production of such gases could help stop the impact of such gases on climate in the adaptation gap report. In the end, we all know that decreasing the amount of pollution in our surrounding atmosphere is one of the best ways to feel better.
