Freezing ocean water expels salt, eventually producing sea ice consisting of fresh water. When that ice melts, it produces lower-density water than salty ocean water. — Credit: National Snow and Ice ...

Melting on the Antarctic Ice Sheet for the 2024 to 2025 season began with above average melt extents in all regions, but melt extent dropped to nearly zero or below average from February 1 to March 15 ...

UN weather agency issues ‘red alert’ on climate change after record heat, ice-melt increases in 2023 The U.N. weather agency is sounding a "red alert" about global warming, citing record ...

Sea ice is frozen ocean water that has an annual cycle of melting during the summer and refreezing in winter. The sea ice floats on the ocean. The region reaches its maximum extent of sea ice in ...

"We found that the Southern Ocean cooling trend is actually a response to global warming, which accelerates ice sheet melting and local precipitation," said Earle Wilson, an assistant professor of ...

Life-supporting energy and nutrients on Titan could come from its surface and core. Organic matter from Titan's atmosphere ...

The United Nations and the Intergovernmental Panel on Climate Change (IPCC) have evaluated the state of water and climate over the past year, revealing deep challenges influenced by global warming, ...

Water from the melting ice often drains into depressions once occupied by the glacier, creating large lakes. Many of these expanding lakes are held in place by precarious ice dams or rock moraines ...

Titan, Saturn's largest moon, is a strange, alien world. Covered in rivers and lakes of liquid methane, icy boulders and ...
