That is why
different projections of boundary changes will produce slightly different results, as you will see in the next few days I suspect.
The reason
why different projections are used is precisely because we have no clue how technology or economic growth are going to change things 100 years down the line.
Scenarios devised by the Intergovernmental Panel on Climate Change don't just involve different estimations of climate sensitivity, they
involve different projections of the spread of renewable energy and efficiency, the development of carbon capture and sequestration (CCS), the rate of deforestation, and all sorts of other social, political, and technological trends.
While the AEO 2017 Reference case continues to model the Clean Power Plan as law, other changes to input assumptions have resulted in
strikingly different projections, relative to AEO 2016.
Differences among models may be caused
by different projections for radiatively active species (see Section 10.2.1.2) and by differences in the formulation of radiative transfer (see Section 10.2.1.4).
Models are based on the most recent SRES data and based on A2, A1B and B1 scenarios, which are based
on different projections of global growth, development and industrialization.
Goldman Sachs released three
different projections for the future of VR and AR by 2025, detailing the potential, the barriers, and the risks.
Ensembles of process - based crop models are increasingly used to simulate crop growth for scenarios of temperature and / or precipitation changes corresponding to
different projections of atmospheric CO2 concentrations.
We want to avoid the worst of the (impacts) we looked at in
these different projections.»
Two
different projections are displayed sequentially onto the aging pages of a found book.
You know that each of our models provides
a different projection of future atmospheric CO2 concentration.
