Mars 50 thousand years ago experienced an abrupt climate change

At the north pole of Mars, traces of recent dramatic changes in climate were found: they occurred about 50 thousand years ago.

Theorists believe that the ice deposits in the mid-latitudes of Mars formed after the melting of its polar caps at a time when the planet’s axis was strongly tilted. We determined that there were traces of this process – canyons and other traces of erosion at the north pole of Mars.

Scientists have concluded that the climate on Mars has changed dramatically after studying the history of the formation of giant canyons at the North Pole. Scientists have found that the spiral pattern consists of many separate segments that arose at different times and are connected to each other in a special way.

Unlike Earth, Mars’s ice store is located only at the planet’s South Pole and is composed of frozen water and carbon dioxide.

The authors of the new work suggest that similar deposits were at the North Pole of the planet, but due to the change in climate, the ice cap melted. Deep groove-canyons remained traces of this.

Presumably, such abrupt changes are associated with changes in the angle of inclination of its orbit. This is indicated by several other unusual landforms on Mars, including the recently discovered traces of water movement along the slopes of the Istok crater.
