The relationship between the concentration of greenhouse gases in the atmosphere and the observed increase in global temperatures over the past century is a direct one. Greenhouse gases, such as carbon dioxide CO2 , methane CH4 , and nitrous oxide N2O , trap heat in the Earth's atmosphere, leading to a phenomenon known as the greenhouse effect. As the concentration of these gases increases, more heat is trapped, resulting in a rise in global temperatures.Over the past century, human activities, such as the burning of fossil fuels, deforestation, and industrial processes, have significantly increased the concentration of greenhouse gases in the atmosphere. This has led to a rise in global temperatures, causing climate change and its associated impacts, such as more frequent and severe weather events, rising sea levels, and loss of biodiversity.To mitigate the effects of greenhouse gases and climate change, several steps can be taken:1. Reduce greenhouse gas emissions: This can be achieved by transitioning to renewable energy sources, such as solar, wind, and hydroelectric power, and by improving energy efficiency in buildings, transportation, and industrial processes.2. Carbon capture and storage CCS : This technology involves capturing CO2 emissions from power plants and industrial facilities and storing them underground, preventing them from entering the atmosphere.3. Reforestation and afforestation: Planting trees and restoring forests can help absorb CO2 from the atmosphere, acting as a natural carbon sink.4. Promote sustainable agriculture: Implementing sustainable agricultural practices, such as no-till farming, crop rotation, and precision agriculture, can help reduce greenhouse gas emissions from the agricultural sector.5. Encourage energy conservation: Promoting energy-efficient appliances, public transportation, and carpooling can help reduce energy consumption and greenhouse gas emissions.6. Support research and development: Investing in research and development of new technologies and practices can help identify more effective ways to reduce greenhouse gas emissions and mitigate the effects of climate change.7. International cooperation: Climate change is a global issue that requires international collaboration. Countries should work together to establish and enforce policies aimed at reducing greenhouse gas emissions and promoting sustainable development.
