Rules:

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.

Summary

The North Pole experienced an extreme warming event, with temperatures soaring more than 20°C above average, nearing 0°C—the melting point of ice.

Scientists attribute this anomaly to a low-pressure system over Iceland directing warm air northward, amplified by unusually warm Atlantic waters.

The Arctic is warming nearly four times faster than the global average, accelerating sea ice loss.

Experts predict Arctic summer sea ice could vanish within two decades.

... and the AMOC will break.

The researchers also mapped some of the consequences of AMOC collapse. Sea levels in the Atlantic would rise by a meter in some regions, inundating many coastal cities. The wet and dry seasons in the Amazon would flip, potentially pushing the already weakened rain forest past its own tipping point. Temperatures around the world would fluctuate far more erratically. The southern hemisphere would become warmer. Europe would cool dramatically and have less rainfall. While this might sound appealing compared with the current heating trend, the changes would hit 10 times faster than now, making adaptation almost impossible (emphasis added).

Hope NYC and Boston and DC and Florida are ready for a +3 foot sea level rise in like 5 to 10 years.

3 meters at this ever increasing rate of "sooner than expected" insurance pulled out for a reason , they study the risk data
