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]
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.
Extreme event attribution, also known as attribution science, is a relatively new field of study in meteorology and climate science that tries to measure how ongoing climate change directly affects extreme events (rare events), for example extreme weather events.
The final synthesis report was finished in March 2023. It includes a summary for policymakers and was the basis for the 2023 United Nations Climate Change Conference (COP28) in Dubai. [1] The first of the three working groups published its report on 9 August 2021, Climate Change 2021: The Physical Science Basis.
The higher values mean higher greenhouse gas emissions and therefore higher global surface temperatures and more pronounced effects of climate change. The lower RCP values, on the other hand, are more desirable for humans but would require more stringent climate change mitigation efforts to achieve them.
Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
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 ...
In the past years, a number of organizations have deployed the concept of a Just Transition with respect to environmental and/or climate justice. [3]With regards to climate change mitigation, the IPCC defines just transition as follows: "A set of principles, processes and practices that aim to ensure that no people, workers, places, sectors, countries or regions are left behind in the ...
