This sub used to have a pretty cool individual named fishmaboi who used to always say Venus by Tuesday , so you know absolute disaster meltdown of the whole planet human extinction coming way too sooner than we even expected.

BOE is short for Blue Ocean Event , it's basically when the arctic ocean has less than 1 million km2 of ice so it becomes blue as opposed to white and thus it significantly reduces its albedo effect and substantially increases the heating of the planet. When the first Blue ocean event happens it's basically game over, the arctic is the air conditioner of the planet so you get very brutal climate that could pretty much kill agriculture, cause multiple breadbasket failures, wet bulb temperatures, extreme weather. BOE is a major feedback loop. Not to mention the arctic has a lot of methane trapped in permafrost when released will make our problems way worse and might give us some ancient viruses, we might get the first one this year or maybe next year , it'll most likely happen before 2030.

this site is a bit on the extreme mcpherson side so you know take it with a grain of salt but their explanation of the BOE is good if you want to learn more and there are links to the youtube channel of amazing Paul Beckwith who frequently posts on this sub.
