mean summer maximum temperature for Bourke, Alice Springs Narrabri and Hay)
The mean
daily summer maximum temperature is only 20.1 degrees, and the mean winter maximum a brisk 11.9 degrees.
Coral reef ecosystems are expected to be at a particularly high risk from increased temperatures because thermal anomalies as little as 1 °C above average
annual summer maximums can cause mass bleaching in adult coral assemblages.
While summer maximums have showed little trend, the annual average Arctic temperature has risen sharply in recent decades.
There is no doubt 2011 was a very warm year in Perth thanks to hot,
dry summer maxima combining with warm, wet winter / spring minima.
Scientists have documented that sustained water temperatures of as little as one degree Celsius above
normal summer maxima can cause irreversible damage.
Analysing the
mean summer maximum temperature differences between Bourke and Charleville, the unadjusted data (Figure 5) indicates that Bourke was, on average, about 2 °C warmer prior to Stevenson screen installation in 1908 than it was in the years following that, with wide year - to - year variations.
