May global report

[Rwood]

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.

Interesting to compare similarities between the global anomaly map at that link to the NASA model/reconstruction late 1600's maps here...

Try this one as well.

Austria had its coolest may since 1991 with the mean temperature is 2.6 below the long term mean.

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.

I recall a seminar a few years back which cited a fairly significant poleward shift from 1979 to present. If you're challenging what is being said now you shoud try engaging the likes of Renwick or Salinger. I don't think there is any reason whatever for complacency.

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!!
