The hydrosphere (from Greek ὕδωρ – hudōr, “water”[1] and σφαῖρα – sphaira, “sphere”[2]) in physical geography describes the combined mass of water found on, under, and over the surface of a planet. http://en.wikipedia.org/wiki/Hydrosphere
Methane hydrates are ice like structures forming a solid similar to ice. Significant amounts have been located under sediments on the ocean floors of the Earth. Generally, methane hydrates are more stable in fresh water than in salt water. A region allowing the formation for methane hydrates (largely dependent on depth and pressure) is called…

Tropical cyclones, which are called hurricanes in the Atlantic, are one of the most destructive weather phenomena. This presentation will explore the links between climate and tropical cyclones, with a focus on how hurricanes and tropical cyclones have changed in the past, and what we think they will do in the future. http://www.atkinson.cornell.edu/events/ClimateChangeSem.php Speaker: Gabriel…
