Comparison of cloud models for Brown Dwarfs
Ch. Helling, A. Ackerman, F. Allard +8
A test case comparison is presented for different dust cloud model approaches applied in brown dwarfs and giant gas planets. We aim to achieve more transparency in evaluating the u…
Implications of "peak oil" for atmospheric CO2 and climate
P. A. Kharecha, J. E. Hansen
Unconstrained CO2 emission from fossil fuel burning has been the dominant cause of observed anthropogenic global warming. The amounts of "proven" and potential fossil fuel reserves…
Scientific reticence and sea level rise
J. E. Hansen
I suggest that a "scientific reticence" is inhibiting communication of a threat of potentially large sea level rise. Delay is dangerous because of system inertias that could create…
Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds
Nancy Y. Kiang, Antigona Segura, Giovanna Tinetti +6
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be…
Spectral signatures of photosynthesis I: Review of Earth organisms
Nancy Y. Kiang, Janet Siefert, Govindjee +1
Why do plants reflect in the green and have a 'red edge' in the red, and should extrasolar photosynthesis be the same? We provide: 1) a brief review of how photosynthesis works; 2)…
