Thwaites Glacier is in the news as its ice loss and floods risk accelerate coastlines; researchers pace defenses amid melting. Antarctic giant, mapped 1959–66.
Researchers funded by the UK government report that pumping seawater onto Arctic ice in Cambridge Bay thickened the surface ice by about 50 cm, offering early signs that refreezing could slow summer melt. The effort, part of Real Ice, is being monitored for long-term impacts on temperature and wildlife.
