Title and Abstract:
Climate on high obliquity planets
Planets with high obliquity may widely exist in absence of a large moon. This type of planets receive more radiation in the polar regions than in low latitudes, making the equator the coldest region over the globe.
Lecture will be available online after March 17th.

The discovery of oceanic black (and white) smokers revolutionized our understanding of mid-ocean ridges and led to the recognition of new organisms and ecosystems resulting from mixing of fluids. Continental smokers, defined here to include a broad range of carbonic springs, hot springs, and fumaroles that vent mantle-derived fluids in continental settings, exhibit many of the same processes of heat and mass transfer and ecosystem niche differentiation.
