It’s not misleading, it’s wrong, the article is about supporting evidence for the Younger Dryas (13,000 years ago) being caused by a meteor strike instead of some internal ice-age cycle.

Also, the impact in the title refers to a meteor impact. Probably OP just misunderstood the article and summarized the title incorrectly. “Meteor crater under Greenland points to climate altering effect of recent meteor strike” would be better.
