Päästettävät

Päästettävät, also known as greenhouse gases, are gases in Earth's atmosphere that trap heat. This process is called the greenhouse effect and is essential for supporting life on Earth. However, human activities such as burning fossil fuels, deforestation, and industrial processes have significantly increased the concentration of päästettävät in the atmosphere, leading to global warming and climate change.

The primary päästettävät include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. CO2 is the most abundant päästettä and is primarily produced by burning fossil fuels for energy, transportation, and industrial processes. Methane is emitted during the production and transport of coal, oil, and gas, as well as from livestock and other agricultural practices. Nitrous oxide is released from agricultural activities, industrial processes, and the burning of fossil fuels. Fluorinated gases are synthetic, powerful päästettävät that are emitted by a variety of industrial processes.

The Intergovernmental Panel on Climate Change (IPCC) has established targets to limit global warming to well below 2 degrees Celsius above pre-industrial levels, with efforts to limit the increase to 1.5 degrees Celsius. To achieve these targets, it is crucial to reduce päästettä emissions and transition to renewable energy sources. International agreements such as the Paris Agreement aim to promote cooperation among countries to mitigate climate change and adapt to its impacts.
