Mitigation Adaptation

Mitigation Adaptation

There are Three “pathways” to meet the UNFCCC’s 2 °C target. They are “global technology”, “decentralised solutions”, and “consumption change”. Each pathway shows how various measures. This is how one could contribute to emissions reductions.

Mitigation of climate change usually are actions to reduce greenhouse gas emissions. Or it usually enhances the capacity of carbon sinks to absorb GHGs from the atmosphere. There is a large potential for future reductions in emissions by a combination of activities. They include energy conservation and increased energy efficiency; the use of low-carbon energy technologies, such asrenewable energy, nuclear energy, and carbon capture and storage. And they enhance carbon sinks through, for example, reforestation and preventing deforestation. A 2015 report by Citibank concluded that transitioning to a low carbon economy would yield positive return on investments.

Near- and long-term trends in the global energy system are inconsistent. And it also limits global warming at below 1.5 or 2 °C, relative to pre-industrial levels. Pledges made as part of the Cancún agreements are broadly consistent. It has also a likely chance (66 to 100% probability) of limiting global warming (in the 21st century) at below 3 °C, relative to pre-industrial levels.

In limiting warming at below 2 °C, more stringent emission reductions in the near-term would allow for less rapid reductions after 2030. Many integrated models are unable to meet the 2 °C target if pessimistic assumptions are made about the availability of mitigation technologies.

Adaptation

Other policy responses include adaptation to climate change. Adaptation to climate change may be planned, either in reaction to or anticipation of climate change, or spontaneous, i.e., without government intervention. Planned adaptation is already occurring on a limited basis.The barriers, limits, and costs of future adaptation are not fully understood.

A concept related to adaptation is adaptive capacity, which is the ability of a system (human, natural or managed) to adjust to climate change (including climate variability and extremes) to moderate potential damages, to take advantage of opportunities, or to cope with consequences. Unmitigated climate change (i.e., future climate change without efforts to limit greenhouse gas emissions) would, in the long term, be likely to exceed the capacity of natural, managed and human systems to adapt.

Environmental organizations and public figures have emphasized changes in the climate. And the risks they entail, while adaptation is usually promoted to changes in infrastructural needs and emissions reductions.
