The transient climate response to cumulative emissions of carbon dioxide (TCRE) is the ratio of the globally averaged surface temperature change per unit carbon dioxide (CO 2) emitted. [1][2] [3] [4] As emitted CO 2 may stay in the atmosphere for thousands of years, this response is the amount that the global temperature changes per the net ...
Shared Socioeconomic Pathways (SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. [2] They are used to derive greenhouse gas emissions scenarios with different climate policies. [3][4][5] The SSPs provide narratives describing ...
The Dynamic Integrated Climate-Economy model, referred to as the DICE model or Dice model, is a neoclassical integrated assessment model developed by 2018 Nobel Laureate William Nordhaus that integrates in the neoclassical economics, carbon cycle, climate science, and estimated impacts allowing the weighing of subjectively guessed costs and subjectively guessed benefits of taking steps to slow ...
RCP 2.6 is a "very stringent" pathway. [4] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
A carbon price is a system of applying a price to carbon emissions, as a method of emissions mitigation. [10] Potential methods of pricing include carbon emission trading, results-based climate finance, crediting mechanisms and more. [11] Carbon pricing can lend itself to the creation of carbon taxes, which allows governments to tax emissions. [10]
An economic analysis of climate change uses economic tools and models to calculate the magnitude and distribution of damages caused by climate change. It can also give guidance for the best policies for mitigation and adaptation to climate change from an economic perspective. There are many economic models and frameworks.
A carbon budget is a concept used in climate policy to help set emissions reduction targets in a fair and effective way. It examines the "maximum amount of cumulative net global anthropogenic carbon dioxide (CO 2) emissions that would result in limiting global warming to a given level". [2]: 2220 It can be expressed relative to the pre ...
Climate stabilization wedges are used to describe possible climate change mitigation scenarios and their impact, through the grouping of different types of interventions into "wedges" representing potential decreases in CO 2 emissions. When stacked on top of each other, wedges form a "stabilization triangle" that represents the estimated amount ...
