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.

There is nothing mysterious about the cold blob. It's due to the land ice in Greenland melting due to global warming. This ice runs into the ocean at greater and greater speeds, cooling off the water in that region. So that little bit of cooling is actually just a part of global warming.

It's like no one's ever put Ice in a glass of water before.

And checked the results with a heat gun? You got me red handed.

Might be that the melt runoff is at a greater rate than before where that cold blob was smaller/not there.

If the cold blob continues to get bigger, the warm surface could get cut off.

That was my thought as well, but wouldn't the behavior be the same near the poles then?

[–] mech@feddit.org 8 points 2 weeks ago

I'm guessing the water at the poles was already close to freezing temperatures.
So it isn't affected by melting ice.
But at latitudes affected by the warm Gulf Stream, melting ice is colder than the surrounding water, so it would cool it down.
