Sentences with phrase «representative concentration pathways»
The phrase "representative concentration pathways" refers to a set of scenarios that depict how human activities, like burning fossil fuels, might impact the concentration of greenhouse gases in the atmosphere. These pathways are used to understand potential future climate change and help scientists and policymakers make informed decisions to combat it. Full definition
These changes are grouped in scenarios called Representative Concentration Pathways (RCP), which offer specific paths that climate changes could take.
