This is not meant to pre-judge whether those risks are worse than climate change impacts under plausible emission scenarios and is not meant to claim that all geoengineering strategies are dangerous or risky.

Not exact matches

«This is worrisome given that the temperature in the study region is predicted to rise by as much as 2 degrees by midcentury under the range of plausible greenhouse gas emissions scenarios,» said Avery Cohn, aassistant professor of environment and resource policy at Tufts, who led the work while he was a visiting researcher at Brown.

Rutledge said of the four IPCC scenarios, he found the second RCP scenario, RCP 4.5, where carbon dioxide emissions flatten out around 2080, to be more plausible under a business - as - usual scenario for coal exploitation.

On the high end, recent work suggests that 4 feet is plausible.23, 3,6,7,8 In the context of risk - based analysis, some decision makers may wish to use a wider range of scenarios, from 8 inches to 6.6 feet by 2100.10,2 In particular, the high end of these scenarios may be useful for decision makers with a low tolerance for risk (see Figure 2.26 on global sea level rise).10, 2 Although scientists can not yet assign likelihood to any particular scenario, in general, higher emissions scenarios that lead to more warming would be expected to lead to higher amounts of sea level rise.

Climate change scenarios are based on projections of future greenhouse gas (particularly carbon dioxide) emissions and resulting atmospheric concentrations given various plausible but imagined combinations of how governments, societies, economies, and technologies will change in the future.

Anthropogenic emissions of CO2 are increasing, and accelerating, and current proposals for reducing them present no plausible scenario in which emissions will actually peak and decline in anywhere near the time frame that is required to avoid what are generally considered «dangerous» levels of CO2 (although points 1 - 3 above suggest that the current levels are more dangerous than has been generally believed).

Thus, climate scientists and energy - economic modelers have developed hundreds of plausible scenarios of future emissions and used them to identify emissions pathways that might achieve climate policy goals.

Each color denotes a plausible scenario of how the world may choose to cut fossil fuel emissions.

On any plausible business as usual scenario, emissions will grow substantially, while for any plausible climate science model, we need to reduce emissions substantially if we are to avoid highly damaging climate change.

It cited «plausible scenarios in which GHG [greenhouse gas] emissions from corn - grain ethanol are much higher than those of petroleum - based fuels,» and questioned the method by which EPA determined that ethanol would produce 21 percent less emissions.

This makes the range of specific emission scenarios that are compatible with a given budget very large, and the choice of how to limit the scenarios considered plausible is important when giving policy advice based on emission budgets.

Similarly, because nearly any plausible scenario would require a large amount of negative emissions later in the century, the carbon budget itself is not a hard cap on emissions.

The Plausible Scenario results show a mitigation impact of 6.7 gigatons of carbon dioxide - equivalent emissions over the period 2020 - 2050.

The Plausible Scenario projects that energy - efficient shipping can lead to an estimated emissions reduction of 7.9 gigatons of carbon dioxide - equivalent greenhouse gases from 2020 - 2050, at an additional cost of approximately US$ 915 billion [10] and a net operating savings of US$ 424 billion.

Intergovernmental Panel on Climate Change model projections for 2100 exceed the full distribution of Holocene temperature under all plausible greenhouse gas emission scenarios.

The RCPs should be based on scenarios published in the existing literature, developed independently by different modeling groups and, as a set, be «representative» of the total literature, in terms of emissions and concentrations (see further in this section); At the same time, each of the RCPs should provide a plausible and internally consistent description of the future;

Demand - side solutions account for 48.0 percent, 44.7 percent, and 40.7 percent of Food Sector emissions reductions in the Plausible, Drawdown, and Optimum Scenarios, respectively.

Under the Plausible Scenario, this solution has a reduced contribution to avoided emissions during 2020 - 2050 of just 0.2 gigatons of carbon dioxide - equivalent greenhouse gas.

This warming must be from various, plausible CO2 emission scenarios, and not from natural causes, of course.

Indeed, one can easily envision the plausible scenario whereby the ESA, operating as federal law separate from the CAA, could prevent state compliance with EPA's emissions targets.

If forests globally were to become a net source of carbon to the atmosphere in the future — an all - too - plausible scenario under climate change — the EF would approach infinity, since additional forest would augment human carbon emissions rather than offset them.

A clear and specific understanding of the plausible worst - case scenario impacts facing the world post-2050 on our current emissions path.
