Mars ended the ice age and global warming has begun

A group of scientists, representing the South-East research Institute in boulder found out that quite recently in geological terms, Mars ended the ice age. Since then and until today the temperature of the planet is gradually increasing. This means that for Mars is characterized by approximately the same cyclical temperature fluctuations, like those observed in Earth’s history.

Ice age on Mars ended just 370-375 thousand years ago — from the point of view of planetary scientists sometimes consider recent events, from the time which passed tens of millions of years, the warming phase has started “recently”. To detect evidence of recent glaciation and more recent thawing, scientists were able with the help of a probe called Mars Reconnaissance Orbiter, previously made a lot of pictures of the ice caps at the North pole of the red planet.

Researchers report that Mars global temperature fluctuations are expressed even brighter than on Earth because the angle of own rotation axis of Mars to the plane of its orbit over the same period of time changed dozens of times stronger than on our planet, which in turn leads to a significant change in the amount of sunlight received at the surface.

The researchers note that for the glacial period is characterized by the cooling of the planet overall, but the warming at the poles, contributing to the distribution of ice in other parts of the surface. So the fact that over 370 of thousands of years on the Martian poles has accumulated over 87 million cubic kilometers of water ice, as paradoxical as it may seem at first glance, suggests that the planet is now in the stage of “thawing”.

The data obtained, according to scientists, can be important in the future, when people will build long-term plans for the colonization and development of Mars. By the way, although these prospects look very distant, the nearest manned mission to orbit the red planet could take place soon enough — in 2028 Godou

A study published in the journal Science.

Recently, by studying deposits of clay in the vicinity of crater Huygens on Mars, planetary scientists have discovered new evidence that in the past on this planet could Harbor life.
