(The above graph shows how temperatures have shifted outside of 20th Century ranges. During 2014-2017, the world dramatically warmed — generating further rightward movement in the bell curve. Temperature has an impact on everything from drought, to the severity of thunderstorms, to the length and intensity of fire season, to the fuel available for the most powerful hurricanes, to algae blooms, to coral bleaching events.

As you can see, there are still cool summers but hot summers outweigh them.

If you want to know why this summer is so hot so early, this “blob” is the reason:

The hot southern seas will see more coral bleaching:

Sea ice tracking low in both hemispheres
February 6, 2018

January of 2018 began and ended with satellite-era record lows in Arctic sea ice extent, resulting in a new record low for the month. Combined with low ice extent in the Antarctic, global sea ice extent is also at a record low.

(From a comment to a blog by RobertScribbler—google him and read his blogs, very strongly science based.

The question, of course, soon becomes: "...Why is that 'blob' the reason for a 'so-hot-so early' summer?

Is it to do with the direction of gyre circulations or what????????????????????

:huh

:grn I wouldn't have a clue,... so why would anyone else? :grn

The less sea ice, the more dark open ocean, the more the sea is warmed up.

Yeh but there is no sea ice in that area off Australia... you're just saying generally of course I suppose!

The Tasman sea looks really hot on that map.
