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.
In a 2024 survey, 76.3% of responding IPCC lead authors and review editors projected at least 2.5 °C of global warming by 2100; only 5.79% forecast warming of 1.5 °C or less. [ 94 ] January: the World Economic Forum projected that, by 2050, directly and indirectly, climate change will cause 14.5 million deaths and $12.5 trillion in economic ...
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 ...
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 ...
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.

Lost Hammer Spring is in Nunavut, Canada, about 1,000 kilometers south of the North Pole. Conditions there are forbidding, but water still flows because it’s extremely salty, up to 24% saline ...
The U.S. space agency's Artemis program aims to put astronauts in the coming years on the lunar surface for the first time since 1972 in preparation for potential future human missions to Mars.
According to Environment and Climate Change Canada "warming over the 20th century is indisputable and largely due to human activities" [25] adding "Canada's rate of warming is about twice the global rate: a 2° C increase globally means a 3 to 4 °C increase for Canada". [26] ECCC lists impacts of climate change consistent with global changes.
