Tesla has fired hundreds of employees from its headquarters in Fremont, Calif., this week, according to the Mercury News. The automaker fired reportedly between 400 and 700 employees across various functions, though the company says it was the result of performance reviews and not layoffs, adding it expects to replace most of the employees.
Why it's happening: "Unlike most recent observations, we think that the channel under Dotson is eroded by warm water, about 1°C, as it circulates under the shelf, stirred clockwise and upward by Earth's rotation," said Noel Gourmelen from the University of Edinburgh.
Why it matters: Ice shelves hold glaciers together and slow their flow into the ocean, which can add to sea-level rise, so researchers want to better understand how canyons like these form and affect their stability.
