Over the 54 - year period, the annual
average of heatwave days was 7.3.

Temperatures passed 40 °C, compared with a seasonal
average of 23 °C, and the
heatwave lasted all
of July and into mid-August.
The researchers studied all 571 European cities to assess the likely impact
of flooding, drought and
heatwaves in the latter half
of the century, under a climate model where
average temperatures rise between 2.6 C and 4.8 C - the current widely accepted business - as - usual trajectory.
A «
heatwave» in mid-November caused some parts
of the Arctic to be 15C warmer than usual, with
average temperatures for November and December across the Arctic as a whole a full 5C above the long term
average, according to the quickfire analysis
of this year's unusual winter.
Of course Mass may feel that a linear regression of average Texas summer temperatures since 1895 provides conclusive evidence for his case that AGW is currently far too weak to play a significant role in the Texas 2011 heatwave (an argument he recycles in his Aug 9 blog post), but it is strange Mass picks on Rupp et al 2012 without mentioning Massey et al 2012 in the same collection of papers that similarly finds AGW impacts in excess of Mass's method (3 times in excess by my calculation

AS Australians sweltered through a record - breaking summer
heatwave this week, one
of the world's leading scientific bodies revised down its five - year projection for the world's
average temperature.
In 2011 and 2012, the number
of heatwaves was almost triple the long - term
average.
Mr Joshi's post includes a graph showing that the
average output
of SE Australia's wind farms, which all feed into the same power grid, generated an
average of around 800MW for the week
of the
heatwaves.
As
average summer temperatures rise in the tropics, so do the risks
of mass death from killer
heatwaves, climate scientists find.
The number
of heatwaves observed in 2011 and 2012 were triple the long - term
average, and require planning for economic, health and environmental tolls.
As an earlier World Bank - commissioned study noted, food stocks plummet,
average summer temperatures reach extreme
heatwave levels across vast swaths
of the world, and sea - level rise threatens to displace hundreds
of millions
of people.
Then they settled down to calculate the likelihood that a proportion
of past
heatwaves or floods could be linked to a measured
average rise in planetary temperatures so far
of 0.85 °C.
They worked out how these proportions would change if the
average planetary temperatures reach 2 °C above the «normal»
of the pre-industrial world, and they found that human - induced global warming could already be responsible for 18 %
of extremes
of rain or snow, and 75 %
of heatwaves worldwide.
The World Meteorological Organization (WMO) released its provisional Statement on the State
of the Climate this week, estimating that 2017 is likely to be one
of the warmest years for global
average surface temperature, with many high - impact events including catastrophic hurricanes, floods,
heatwaves and droughts.
The BoM's Special Climate Statement includes a breakdown
of each state's
heatwave including 7 January, and the BoM's area -
averaged estimate can be compared with the actual
average maximum
of all stations:
So the authors are pretty confident that
average and maximum temperatures look set to rise - and that our greenhouse gases have increased the odds
of heatwaves like the one in 2003.
During a
heatwave in North America on 22 July, when grid operators were experiencing record demand peaks and prices had shot up to 10 times the 2011
average — US$ 530 / MWh — EnerNOC provided over 1,200 MW
of demand response across several U.S. states and Ontario, effectively delivering «negawatts» into the system.
A prolonged, record - breaking, and unusually «muggy»
heatwave enveloped nearly all
of California for multiple weeks, and temperatures have only fallen back to
average over the past few days.
