Meanwhile, other scientists describe RCP 8.5 concentrations as unlikely, yet plausible, on the business-as-usual path and note that RCP 8.5 is consistent with the current pace of global emissions. Some scientists argue that RCP 8.5 may in fact under-estimate future concentrations of atmospheric carbon on the business-as-usual path. There is a scientific debate about whether RCP 8.5 is a plausible and accurate representation of the concentrations of atmospheric carbon that would be reached on the business as usual path. Image Credit: Neil Craik, University of Waterloo The researchers who developed the RCP 8.5 scenario describe the pathway in detail here. RCP 8.5 is often contrasted with RCP 2.6, which would deliver a total warming of about 1.8˚C by 2100. The RCP 8.5 pathway delivers a temperature increase of about 4.3˚C by 2100, relative to pre-industrial temperatures. RCP 8.5 refers to the concentration of carbon that delivers global warming at an average of 8.5 watts per square meter across the planet. the level) of carbon in the atmosphere, not the volume of carbon emissions. Each scenario defines a pathway in terms of the concentration of carbon in the atmosphere at any date – note that these pathways are defined in terms of the concentration (i.e. RCP 8.5 is one of a suite of scenarios (Representative Concentration Pathways) that describe several potential future pathways. Parsing of the various views may conclude that the temperatures encountered on the current business-as-usual path would likely fall short but come very close to the temperatures projected by RCP 8.5, particularly if the carbon warming feedbacks expected on the business-as-usual path come to pass. Further, there are questions about whether RCP 8.5 is consistent with the current trajectory of emissions and whether RCP 8.5 represents the alternate pathway offered by those world leaders championing the use of fossil fuels.

Send us feedback about these examples.In the characterization of climate change projections, there is debate over whether the climate change scenario RCP 8.5 represents a “business as usual” scenario, a “high emissions” scenario, or a “worst-case” scenario. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'usual.'
