Nearly 100 scientists and support staff departed this week for the most ambitious mission to date for Thwaites Glacier in West Antarctica.
An iceberg the size of Delaware has broken free from an Antarctic ice shelf, leaving the rest of the shelf vulnerable to collapse and serving as a harbinger of future sea-level rise that could pose a serious threat to coastal communities such as the Falkland Islands.

A number of penguin species found in western Antarctica are declining as a result of a fall in the availability of krill, a study has suggested. Researchers, examining 30 years of data, said chinstrap and Adelie penguin numbers had been falling since 1986.
