A large doughnut shaped cloud appears in the north polar region of Mars around the same time every Martian year and of about the same size. [88] It forms in the morning and dissipates by the Martian afternoon. [88] The outer diameter of the cloud is roughly 1,600 km (1,000 mi), and the inner hole or eye is 320 km (200 mi) across. [89]
North America, Europe, Africa and South America all had their warmest year on record in 2024, while Asia and the Arctic had their second-warmest year. Still, the overall warming trend is clear.
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 ...
The IPCC Fifth Assessment Report (AR5 WG1) of 2013 examined temperature variations during the last two millennia, and concluded that for average annual Northern Hemisphere temperatures, "the period 1983–2012 was very likely the warmest 30-year period of the last 800 years (high confidence) and likely the warmest 30-year period of the last ...
It was the clearest sign yet that this year’s destructive wildfire season had shaken up the debate over what to do about climate change. What a day on Mars will do: Californians have new urgency ...
For the first time since 2022, a total lunar eclipse will cause the moon to turn red as it passes through the Earth's shadow. Unlike a total solar eclipse that is visible from only a small area ...
During the winter season on Mars, temperatures at the planet’s polar caps can reach below CO 2 ’s condensation temperature (150 K). Noted as orbit #10075 by Dr. Ivanov and Dr. Muheleman of the Mars Global Surveyor, data from the MOLA instrument recorded cloud returns at the planet’s south polar cap during the southern winter season.

Mars has lots of water, but future astronauts won't exactly be able to scoop it into bottles -- it's generally trapped in ice deposits below the surface. Scientists from Penn State think climate ...
