The results of such models will be compared to the ever growing exoplanet database, as we work to understand what conditions are necessary to produce the observed exoplanet systems, both in
terms of their orbital architectures and
atmospheric compositions.
I will discuss the range of magma ocean planets that may be in our current exoplanet sample and some of the implications for
atmospheric composition and long -
term evolution of these planets.
[Response: Changes in the
atmospheric composition are negligible for their effect on the gas law, but not in
terms of radiative transfer, so your conclusion is invalid.]
Also, geoengineering is an awfully vague
term — haven't we been doing geoengineering for the past 150 years by altering the
atmospheric composition?
And here's another paper The long -
term carbon cycle, fossil fuels and
atmospheric composition by Berner.
Continued growth of greenhouse gas emissions, for just another decade, practically eliminates the possibility of near -
term return of
atmospheric composition beneath the tipping level for catastrophic effects.
Here above, Jim Hansen says «Continued growth of greenhouse gas emissions, for just another decade, practically eliminates the possibility of near -
term return of
atmospheric composition beneath the tipping level for catastrophic effects.»
panel cautions that trends in such short periods of record with arbitrary start and end points are not necessarily representative of how the atmosphere is changing in response to long -
term human - induced changes in
atmospheric composition.
Emissions was only a rough ball park method to define scenarios in
terms of
atmospheric composition; and for that it works fine.
Specifically, has anyone here framed the issue in
terms of, «changing the
composition of a substance changes its properties» — and then related that to activities ranging from cooking, to metallurgy, to biotechnology, to the
atmospheric effect of taking lead out of gasoline?
For the long -
term, it is important to encourage development now of technologies that will lead to reduced emissions or will capture and sequester CO2 at power plants, in order to be able to stabilize
atmospheric composition in the second half of the century.
the reason the period of the last 1000 years isn't much of a priority in
terms of paleo simulations is that you need some specified change to external forcing (solar,
atmospheric composition) or bottom boundary conditions (like continents moving around) to get a simulation that is different from present.
