Drivhusgasniveauer

Drivhusgasniveauer, also known as greenhouse gas levels, refer to the concentration of gases in the Earth's atmosphere that trap heat and contribute to the greenhouse effect. The primary greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. These gases are essential for maintaining the Earth's temperature, but their levels have been increasing due to human activities such as burning fossil fuels, deforestation, and industrial processes.

The Intergovernmental Panel on Climate Change (IPCC) has documented that the global average concentration of CO2 has risen from about 280 parts per million (ppm) in pre-industrial times to over 410 ppm in 2020. Similarly, methane levels have more than doubled since pre-industrial times, reaching around 1,875 parts per billion (ppb) in 2020. These increases are primarily attributed to human activities, particularly the burning of fossil fuels and agricultural practices.

Elevated greenhouse gas levels lead to an enhanced greenhouse effect, causing the Earth's temperature to rise. This phenomenon, known as global warming, has significant implications for the environment, including melting glaciers, rising sea levels, and more frequent and severe weather events. Addressing the issue of drivhusgasniveauer requires global cooperation to reduce emissions and transition to renewable energy sources.
