Arctic sea ice has declined by more than 42% since 1979, when regular satellite monitoring began. As the ice grows thinner and recedes, more water is exposed to sunlight.

Century-Scale Effect Of Climate Change On Meteorite Falls
Climate change is inducing a global atmospheric contraction above the tropopause (~10 km), leading to systematic decrease in neutral air density.
![Site locations and hypothesized pan-Arctic glaciation. ODP Site 910 and MD99-2277 (red dots) are located in the Eurasian sector of the Arctic Ocean and central Nordic Seas, respectively. Site 910 lies just beyond the margins of the maximum MIS 2 Eurasian ice sheets [gray dashed line; based on (51)], while MD99-2277 was simultaneously covered by sea ice. However, both sites are hypothesized to have been fully glaciated under the maximum pan-Arctic ice sheet extent (white shaded extent with blue flow lines) proposed by Hughes et al.

(3)]. - Science Advances](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/07/Ice-World-Oceanography-The-Arctic.png?resize=1200%2C718&ssl=1)

New Fossils From Earth’s Most Famous Extinction Show Climate Tipping Point Was Crossed
The collapse of tropical forests during Earth’s most catastrophic extinction event was the primary cause of the prolonged global warming which followed, according to new research.

During Snowball Earth Early Life May Have Sheltered In Meltwater Ponds
When the Earth froze over, where did life shelter? MIT scientists say one refuge may have been pools of melted ice that dotted the planet’s icy surface.
