4th warmest (global, land + sea). For Southern hemisphere land, it was the warmest on record.  The coldness over a substantial part of the USA and Europe gave a misleading impression - there was a significant difference between the two hemispheres.

As with geopolitics, the intrigue following weather and climate is on a rising trajectory now.  The next 10-20 years should settle things.  Either way there are some hefty predictions being made by big names/institutions and it'll be messy.  As part of geology degree I did some climate science, 25+ years ago so very rusty.  A central and solid prediction reinforced by several lecturers at the time was that by now the Hadley cells would have expanded to the point NZ would be in a state of near perma-drought with the circum-Antarctic vortex/roaring forties being suppressed south.  It's rather like trying to measure pedesis of a happy dogs tail... but they're crowing about roughly a degree of arc pole-ward expansion at this point.  The narrative I paid good money for has proven largely divergent of reality... it has obviously warmed somewhat though.

Jet stream non-linearity seems to be rocking the boat of late.

Timely to note now that various locations in Northland, Auckland and Waikato reported record low rainfalls to the end of June - the kind of scenario predicted years ago as occurring more frequently in the future - not for the whole of NZ as implied by a post above!!
