@joachim do we have the keys to determine if this is short term anomaly in a path to global rising or if this is the clue of passed tipping points that put us a whole new trajectory?
@Julianoe @joachim i really am not and expert; it could be that but it could also be the sulfur/ aerosol ban in shipping. See this

@[email protected] i am not an expert but yes, apart from el nino (ehich had an impact last year but doesn’t explain overall, sustained step change) the sulphur ban is def a possible explanation. Hansen suggested this in a paper last year that the majority of climate scientists were sceptical of, eg M Mann, but i think slowly others are considering this explanation too. However, still not fully accepted so may not be right. Adding this recent article just shared by @[email protected] https://www.nature.com/articles/s43247-024-01442-3
