Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Washington (AFP) – A mile-thick ice sheet in Greenland vanished around 416,000 years ago during a period of moderate natural warming, driving global sea rise to levels that would spell catastrophe for coastal regions today, a study said Thursday. In a dark room, scientists took interior strips of the ice core and exposed them to blue-green or infrared light, releasing trapped electrons that form a kind of ancient clock that shows the last time they were exposed to sunlight, which erases the luminescence signal. “And the only way to do that at Camp Century is to remove a mile of ice,” said Tammy Rittenour, a co-author of the study at Utah State University. " Plus, to have plants, you have to have light." Coastal cities imperiled The Camp Century core was taken only 800 miles from the North Pole, with the study showing the entire region would have been covered in vegetation.

Geological time is crazy. On a scale where little of note happens in less than 10s of millions of years I get that 416,000 is recent but it does feel a bit click-baity to not specify that you mean recent in geological terms.
