Musk subpoenas Twitter whistleblower

Elon Musk has formally subpoenaed a Twitter whistleblower to share information about spam accounts at the social network, as the billionaire fights in court to back out of a massive buyout deal. Musk has tried to pull out of the $44 billion agreement by saying Twitter misled him on the number of false accounts, prompting strong denials and a lawsuit from the social media firm. The Tesla boss hopes that allegations made by former Twitter security chief Peiter Zatko, about major security gaps and problematic practices at the firm, will bolster his case. According to court documents, Musk's attorneys served Zatko with a subpoena on Saturday.

Melting ice to raise sea level by 27 cm, study says

Greenland's rapidly melting ice sheet will eventually raise the global sea level by at least 27 centimeters, according to a study published on Monday. That is because of something that could be called zombie ice. That is doomed ice that, while still attached to thicker areas of ice, is no longer getting replenished by parent glaciers now receiving less snow. Without replenishment, the doomed ice is melting from climate change and will inevitably raise sea levels, said study co-author William Colgan, a glaciologist at the Geological Survey of Denmark and Greenland.
