Greenland's ice sheet has reached the "point of no return" and would continue to melt even if the climate crisis were halted, a new study has found. The study, published in the journal Communications Earth & Environment Thursday, used more than 30 years of satellite data to determine that the ice sheet would continue to shrink even if surface melting decreased.

At the start of the week, Liam Porr had only heard of GPT-3. By the end, the college student had used the AI model to produce an entirely fake blog under a fake name. It was meant as a fun experiment. But then one of his posts found its way to the number-one spot on Hacker News. Few people noticed that his blog was completely AI-generated. Some even hit “Subscribe.”
