temperatures.
While the changes in both the mean and higher order statistical moments (e.g., variance)
of time - series
of climate variables affect the frequency
of relatively simple
extremes (e.g.,
extreme high
daily or monthly
temperatures, damaging winds), changes in the frequency
of more complex
extremes are based on changes in the occurrence
of complex atmospheric phenomena (e.g., hurricanes, tornadoes, ice storms).
In particular, the report authors predicted that with climate change there would be an increase in certain types
of extreme weather, including
daily high
temperatures, heat waves, heavy precipitation and droughts, in some places.
Number
of days in each year where the Australian area - averaged
daily mean
temperature is
extreme.
Since the TAR, the observational basis
of analyses
of extremes has increased substantially, so that some
extremes have now been examined over most land areas (e.g.,
daily temperature and rainfall
extremes).
Another really key thing regarding Bristlecone sites is that the amount
of daily, day to day and annual
temperature variation is
extreme, possibly near or at the most
extreme levels found anywhere in the world.
A summary
of the report released in November predicts an increase in certain types
of extreme weather, including
daily high
temperatures, heat waves, heavy precipitation and droughts, in some places.
«It is likely that anthropogenic influences have led to warming
of extreme daily minimum and maximum
temperatures at the global scale.
An increase
of daily temperature variability is observed during the period 1977 to 2000 due to an increase in warm
extremes, rather than a decrease
of cold
extremes (Klein Tank et al., 2002; Klein Tank and Können, 2003).
Weather is the
daily temperature, it can fluctuate to each
extreme rapidly whereas climate is an average
of temperatures over a long period
of time.
We examine a range
of climate
extremes, comprising the 10th and 90th percentiles of daily maximum (TX) and minimum (TN) temperatures, the 90th percentile of daily precipitation (PR90), and the 27 core Climate Daily Extremes (CLIMDEX)

The University
of Western Australia's Ryan Lowe led a team
of researchers who studied a reef system off the coast
of northwestern Australia, as well as other reef systems across the globe, in order to develop a new model for predicting how rapid sea level rise will impact
daily water
temperature extremes within these shallow reefs over the next century.
Such a decrease is partly related to a reduction
of cold
extremes, which are primarily associated with the increased mean
of the
daily minimum
temperature.
Dependence
of extreme daily maximum
temperatures on antecedent soil moisture in the contiguous United States during summer
We will use long term
daily station data from the US and Europe reaching back to the 19th century to find changes in
extremes of daily, monthly and seasonal minimum and maximum
temperature, as well as
extreme monthly and seasonal
temperatures over the period.
But the datasets are not flawless (biases can occur, for example, when stations are being relocated, or when instrumentation is exchanged) and their monthly resolution is too coarse for studies
of fine - scale climate features such as changes in
daily temperature extremes.
A related aspect
of temperature extremes is that there is likely to be a decrease in the
daily (diurnal)
temperature range in most regions.
''... these changes have had the greatest impact on the
extremes of the distribution and we conclude that the distribution
of global
daily temperatures has indeed become «more
extreme» since the middle
of the 20th century.»
It is worth noting that the Bureau carried out
extreme temperature analysis, namely the frequency
of record - setting
daily temperatures, while excluding all negative diurnal
temperature range results.

Using existing output data from global climate models, the researchers plotted projections
of changes in global average
temperature and rainfall against regional changes in
daily extremes.
The plateau
of global
temperatures over the past two decades — «the pause» — is disproportionate to the increase in climate alarmism which coincides with the rise
of mobile / video phones and CCTV, with
extreme weather content captured and uploaded to social media, and lovingly aired by CAGW - sympathetic mainstream media, leading to the mass climate hysteria we bear witness to
daily.
Indices
of temperature extremes have been calculated from station data, including some indices from regions where
daily station data are not released (Frich et al., 2002; Klein Tank and Können, 2003; Alexander et al., 2006).
