  2. Climate of Mars - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Mars

    Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738.. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from the Earth with help from a telescope.

  3. Groundwater on Mars - Wikipedia

    en.wikipedia.org/wiki/Groundwater_on_Mars

    Some of these layers may have resulted from climate change. The tilt of the rotational axis of Mars has repeatedly changed in the past. Some changes are large. Because of these variations of climate, at times the atmosphere of Mars would have been much thicker and contained more moisture. The amount of atmospheric dust also has increased and ...

    en.wikipedia.org/wiki/Water_on_Mars

    Rocks on Mars have been found to frequently occur as layers, called strata, in many different places. [380] Layers form by various ways, including volcanoes, wind, or water. [381] Light-toned rocks on Mars have been associated with hydrated minerals like sulfates and clay. [382] Layers on the west slope of Asimov Crater. Location is Noachis ...

    The presence of the water may mean big things for Martian biology as well as for our understanding of the planet’s history, but we are no closer to one day being able to live off the Martian land.

    en.wikipedia.org/wiki/Argyre_quadrangle

    The climate of Mars may have been such in the past that water ran on its surface. It has been known for some time that Mars undergoes many large changes in its tilt or obliquity because its two small moons lack the gravity to stabilize it, as the Moon stabilizes Earth; at times the tilt of Mars has even been greater than 80 degrees [ 48 ] [ 49 ]

    The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...

    Mars without a dust storm in June 2001 (on left) and with a global dust storm in July 2001 (on right), as seen by Mars Global Surveyor Local and regional dust storms are not rare on Mars. [ 14 ] [ 2 ] Local storms have a size of about 10 3 km 2 and occurrence of about 2000 events per Martian year, while regional storms of 10 6 km 2 large are ...

  9. 2 Degrees Will Change The World - The Huffington Post

    World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
