For headline, yes it is game over. Video is too long. While 1.5C isn’t a magical threshold for tipping points, it is an approximate one. Planet will not be cooling from here. War is huge in boosting short term use and prices and desperate FF projects ensures long term use at any price.
Tipping point for forest fires and permafrost thaw has already been breached. Lumber tariffs will make forest fires worse. While energy sector in many regions has shown peak FF use, Atmostpheric CO2 concentration rose by a near record last year. War and forest fires likely the culprit.
AMOC effects are misunderstood. Europe likely to stay/get warmer every winter, as Atlantic overall gets warmer. AMOC slowdown is just tropical Atlantic getting extra hot, but the heat will still move north, and Arctic ice extent/volume will ensure longer summer that makes European/Arctic winters warmer, and ever hotter northern Atlantic end of summer temperatures.
