Climate on Mars changes at a wide range of time scales; these changes leave observable traces in the geological record of the planet. Recent decade of intensive orbital imaging of Mars has revealed a fascinating set of geologically young features indicating different climate conditions: recent gullies, surprisingly dynamic high-latitude landscapes, a wealth of new information about the polar layered deposits, traces of huge extinct tropical mountain glaciers, impressive remnants of wide-spread mid-latitude glaciation, etc. However, the whole progression of the climate-related geological events remains rather opaque. Dr. Kreslavsky will systematically overview current ideas, points of emergent understanding and the key questions in reading the geological record of martian climate.
