A number of possible policy responses can be adopted in order to address the prospect of increasing greenhouse gases in the earth＇s atmosphere, These include mitigation measures, that reduce greenhouse gas emissions or enhance the processes that remove greenhouse gases from the atmosphere, adaptation measures that reduce the consequences or damages from climate change, and information measures, including scientific research on climate processes and research and development on new energy technologies, Climate research can reduce current uncertainties about the consequences of greenhouse gas emissions and new energy technologies can reduce the costs of mitigation measures, All of these measures have a role in a balanced approach to climate policy.
