Jacques Laskar, of France's National Centre for Scientific Research, argues that the effects of these periodic climate changes can be seen in the layered nature of the ice cap at the Martian north pole. [133] Current research suggests that Mars is in a warm interglacial period which has lasted more than 100,000 years. [134]
Thursday's weather will feature an Arctic blast for the Midwest and Northeast and still more lake-effect snow for the Great Lakes. Cold air associated with a high-pressure area will move over the ...
The Summary. NOAA's winter forecast outlook predicts above-average precipitation in the Northwest and Great Lakes regions. The rest of the country faces either an average or warm and dry winter.
In summer 1965, the first close-up images from Mars showed a cratered desert with no signs of water. [1] [2] [3] However, over the decades, as more parts of the planet were imaged with better cameras on more sophisticated satellites, Mars showed evidence of past river valleys, lakes and present ice in glaciers and in the ground.

Snow to belt the Great Lakes. Snow will still fly this weekend in the snow belt regions of the Great Lakes: "The persistent flow of arctic (air) over the relatively warm waters of the Great Lakes ...
1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
Lake effect snow is forecast to wallop the already snow-buried Great Lakes region, while much of the continental U.S. will experience below-freezing temperatures over the next few days.
Mars has an axial tilt of 25.19°, quite close to the value of 23.44° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times. However, the orbit of Mars has significantly greater eccentricity than that of Earth. Therefore ...
