While it takes into account earlier planning exercises in arctic research, it also includes some ideas that have not been explicitly articulated previously, such as defining NSF's possible role in contaminant studies, the importance of long - term observations and monitoring as a foundation for basic research in the Arctic, and the significance of the Arctic in high atmosphere studies.

MAVEN will also determine how much Martian atmosphere has been lost over time by measuring the isotope ratios of other elements in the very high atmosphere, such as nitrogen, oxygen, carbon, and noble gases like argon. (lasp.colorado.edu)
Geoengineering methods that don't remove carbon dioxide from the atmosphere don't undo the other effects of high atmosphere carbon - dioxide concentrations such as ocean acidification, and our ability to adequately control geoengineering with sunlight - reflecting particles is not certain.
