Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. [299] It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. [300]
This is a list of climate change initiatives of international, national, regional, and local political initiatives to take action on climate change (global warming). A Climate Action Plan (CAP) is a set of strategies intended to guide efforts for climate change mitigation .
These historical impacts of climate change can improve human life and cause societies to flourish, or can be instrumental in civilization's societal collapse. The study seeks to define periods in human history where temperature or precipitation varied from what is observed in the present day.
These policies can be specific to climate change mitigation or adaptation, or of a more generic nature but with an impact on greenhouse gas emissions. Many of the signatory parties to the UNFCCC have by now established climate change strategies and response measures. The REDD+ approach has a similar, more focused set of policies and measures.
This approach is the dominant one where all world governments are engaged, which makes sense as the entire population of the world is affected by this issue. The top-down approach is that of strong central oversight by a majority of world governments in determining how various approaches to climate change mitigation should be implemented. [9]
Some researchers have estimated that the number of wedges needed to mitigate climate change may be much higher. [6] [9] [4] A 2020 update by the Carbon Mitigation Initiative projected mitigation efforts to 2060 with eight wedges. [1] Both the urgency and the difficulty of achieving substantial changes are emphasized. [4]
Climate action (or climate change action) refers to a range of activities, mechanisms, policy instruments, and so forth that aim at reducing the severity of human-induced climate change and its impacts. "More climate action" is a central demand of the climate movement. [1] Climate inaction is the absence of climate action.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
