Icy Martian mysteries / Victor R. Baker.
Title: | Icy Martian mysteries / Victor R. Baker. |
Author(s): | Baker, Victor R. |
Date: | 2003. |
In: | Nature. (2003.), Vol. 426(6968) (2003) |
Abstract: | News and views piece prompted by article in same issue by Head et al, who present evidence for geologically recent ice age on Mars, occurring about 2.1 to 0.4 Myr ago. Claims Head's paper as example of "investigator" role of geologist and summarises evidence used to form Martian ice age hypothesis. Contrasts warm "ice age" phases of ice accumulation on Mars with Earth's system of warm "greenhouse" stability punctuated by metastable cold periods of glaciation. Suggests that existence of a second climate system in which small orbital variations create major instabilities may help to understand how stable climatic state flips between icehouse and greenhouse on both Earth and Mars. |
Notes: | Nature. Vol. 426(6968) :779-780 (2003). |
