Have a look at post 6, why would I recommend for people read the report if I hadn't done so myself.
Big noting yourself? I don't know.
So let's have a look at that Abstract.
"The findings indicate that human-caused climate change greatly increased the risk for the extreme heat waves assessed in this report. How human influence affected other types of events such as droughts, heavy rain events, and storms was less clear,
indicating that natural variability likely played a much larger role in these extremes. "
Maybe natural variability played the whole role?
Heat waves - "The Australian summer of 2012/13 was the warmest since records began in 1910 (Bureau of Meteorology 2013a). "
Actually records go back further than 1880. Back then, like now, there were large areas of the continent with no weather stations. So much for measuring heatwaves in Australia.
California Droughts - "The 2013 event in historical context. The 12-month precipitation and GPH anomalies are both unprecedented in the observational record (Fig. 2.1a,e). "
Figure 2.1c only goes back to about 1900. California has longer records than that.
Then of course we have "BEGINNING about 1,100 years ago, what is now California baked in two droughts, the first lasting 220 years and the second 140 years. Each was much more intense than the mere six-year dry spells that afflict modern California from time to time, new studies of past climates show. The findings suggest, in fact, that relatively wet periods like the 20th century have been the exception rather than the rule in California for at least the last 3,500 years, and that mega-droughts are likely to recur."

Heavy rain events - "Nonetheless, the 2013 heavy rainfall event was large in spatial scale. Weather predictability of the event per se is not addressed herein (see Hamill 2014), but rather how
climate change may have affected the relative likelihood of heavy precipitation in this large region. For this purpose, the
modeled statistics of heavy five-day rainfall of the recent 30-year period (1983–2012) are compared to that of the last 30 years of the 19th century."
Right climate models again.
Storms - " While these anomalies were significantly less than those associated with other blizzards in the region, they were comparable to 24 major snowstorms in Grumm and Hart (2001). These
moderately strong anomalies suggest the storm system was intense, regardless of season, but not unprecedented in terms of 500-hPa heights."
Oh, NOT unprecedented.
Perhaps you did read it, just didn't understand it.
