For those of you think- “Gee it’s been hot with all these heat waves lately- it must be even worse up north”.
Here’s a plot of maximum temperatures across Northern Australia (the area north of 26 degrees south) since 1985- the 29 years to the end of the hottest year on record.
That trend is actually (very slightly) negative.
And yes of course it’s cherry picked- but 2014 will have to be a hotter than average year to make the 30 year trend positive- a 2014 anomaly of +0.35C gives a 30 year trend of: zero. (The mean of 1985-2013 maxima is +0.28C, the median is +0.34C.)
I guess the BOM is not hoping for a La Nina.
