"Emissions scenarios" refer to hypothetical situations or projections that estimate the amount of greenhouse gas emissions that may be released into the atmosphere in the future. These scenarios provide a way to understand and plan for potential future levels of pollution and their impact on climate change.
Full definition
To make a long story short, for terrestrial carbon models, the latter dominates, despite the wide range
of emission scenarios included.
I am thinking particularly of past special reports
on emissions scenarios that generated «IPCC scenarios» rather than assessing scenarios [already available] in the literature.
The
low emission scenario would require carbon emissions by global human society to decrease by 75 percent during this century.
Figure A shows the temperature change under such a «business - as - usual»
emissions scenario in a simple climate model.
The report will lay out projections for climate change through the end of the century, based upon four different
carbon emission scenarios.
Researchers have identified
feasible emission scenarios that could keep carbon dioxide below levels that some scientists have called dangerous for climate.
If so: they have already failed, as the current temperatures are below the predicted ones for the
real emissions scenario.
Using more
sophisticated emissions scenarios and newer models, they find a greater decrease in summer precipitation and a greater increase in annual precipitation than was found by earlier studies.
Real world temperature is tracking the
commitment emissions scenario, i.e., emissions - held - at - year - 2000 level in the AR4 and Fig 1 charts.
These will be used with the greenhouse
gas emissions scenarios to provide a consistent data set for assessing how climate change may impact societies, and what can be done to adapt.
The key difference from figure A is that much lower population and economic growth rates are assumed in this
lower emissions scenario.
The researchers then ran their ice sheet model to simulate how the glaciers responded to global temperature rise under a medium -
high emissions scenario.
Under a more
moderate emissions scenario, the county can expect nearly 20 weeks of cold temperatures each year, on average, by late century.
This is because, when we talk about
carbon emission scenarios and climate sensitivity, we are ultimately talking about future risk management.
The best estimates of the increase in global temperatures range from 1.8 to 4.0 degrees C for the
various emission scenarios, with higher emissions leading to higher temperatures.
This is more than 50 % higher than the old projections (18 — 59 cm) when comparing the
same emission scenarios and time periods.
