The UN’s climate panel has published its strategies for climate change mitigation. Such document from the Intergovernmental Panel on Climate Change (IPCC) looks at options in preventing or limiting greenhouse gas emissions and promoting activities that would get rid of them in the atmosphere.
What is climate change mitigation?
Mitigation pertains to the efforts of cutting or preventing greenhouse gas emissions – these limit the degree of warming in the future. This includes attempts to get rid of greenhouse gases from the atmosphere. It is different from what they call climate change adaptation, which pertains to actions that should be taken in order to manage the inevitable effects of climate change. Adaptation is discussed in the IPCC’s group 2 report.
Mitigation may require changes in people’s behavior, sources of clean energy, new technologies, and the more efficient use of older technologies.
Which technologies are helpful?
Shifting to nuclear energy, hydroelectric, geothermal, solar, wind power and other low-carbon energy sources is among the main strategies in lowering greenhouse gas emissions in the atmosphere.
Taking renewable energy from resources that don’t get consumed through time is ever increasing. Figures from the UN reveal that renewable energy has raised its total energy generation in the previous year from 7.8% to 8.5%. They have also revealed that investments have fallen to at least 14%.
Such technologies are still facing barriers relating to capital costs (such as costs for building and maintaining the plants), public perception, financing, and a long-lasting dependence of institutions and markets on the use of fossil fuels.
The IPCC’s third report mentioned a lot of renewable energy technologies that have progressed in both cost and performance, and the roles they have in providing energy security and reducing air pollution outweigh other disadvantages.
The degree of such challenge is immense since fossil fuels constitute 80% of the energy on earth. Technologies like carbon capture and storage (CCS) can help reduce the bad effects.
