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

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.
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.
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.
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.
