Role of Emission Gases in Global Warming

Greenhouse Effect

Emission gases, like carbon dioxide (CO2), trap heat in the atmosphere, creating a greenhouse effect. This leads to an increase in Earth's average temperature.

Carbon Dioxide

The largest contributor to global warming, CO2 is released from burning fossil fuels, deforestation, and industrial processes. It lingers in the atmosphere for centuries, intensifying the greenhouse effect.

Methane (CH4) Emissions

Methane, from livestock, agriculture, and fossil fuels, has a short-term but potent warming effect. It traps heat over 20 times more effectively than CO2 over a 100-year period.

Nitrous Oxide

Agricultural practices and industrial activities release N2O, a greenhouse gas 300 times more potent than CO2. It contributes to both global warming and ozone depletion.

Fluorinated Gases

Synthetic gases used in refrigeration, electronics, and aerosols are extremely effective at trapping heat. Some fluorinated gases can remain in the atmosphere for thousands of years.

Deforestation

Cutting down trees reduces Earth's ability to absorb CO2, accelerating global warming. Deforestation also releases stored carbon, further intensifying the issue.

Ocean Acidification

Emission gases dissolve into oceans, causing them to become more acidic. This harms marine life and disrupts ecosystems, impacting the planet's carbon cycle.

Positive Feedback Loops

As the Earth warms, natural systems release more greenhouse gases. For instance, melting permafrost releases methane, creating a feedback loop that amplifies global warming.

Rising Sea Levels

Global warming leads to the melting of glaciers and ice sheets, causing sea levels to rise. This endangers coastal communities and ecosystems.

Mitigation Strategies

Reducing emission gases through renewable energy adoption, afforestation, sustainable farming, and international agreements like the Paris Agreement is crucial to combat global warming and its effects.
