Climate change adaptation

IPCC reports cover the "scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation."
The Intergovernmental Panel on Climate Change (IPCC) defines adaptation as: 'the process of adjustment to actual or expected climate and its effects.

Climate change mitigation

mitigationMitigation of global warmingclimate protection
IPCC reports cover the "scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation."
According to the IPCC's 2014 assessment report, "Mitigation is a public good; climate change is a case of the 'tragedy of the commons'. Effective climate change mitigation will not be achieved if each agent (individual, institution or country) acts independently in its own selfish interest (see International cooperation and Emissions trading), suggesting the need for collective action. Some adaptation actions, on the other hand, have characteristics of a private good as benefits of actions may accrue more directly to the individuals, regions, or countries that undertake them, at least in the short term. Nevertheless, financing such adaptive activities remains an issue, particularly for poor individuals and countries."

Greenhouse gas

The United States Environmental Protection Agency and State Department wanted an international convention to agree restrictions on greenhouse gases, and the conservative Reagan Administration was concerned about unrestrained influence from independent scientists or from United Nations bodies including UNEP and the WMO.
At current emission rates, temperatures could increase by 2 °C, which the United Nations' IPCC designated as the upper limit to avoid "dangerous" levels, by 2036.
