What's that got to do with climate change, Alan? Every location on the planet, in every lifetime of every creature since the beginning of life, will receive a record temperature, a record rainfall, a record drought and a record storm, whether hurricane, tornado, cyclone or gusty wind.
While true in general, we're not talking about outliers but rather about a number of trends that basically point in the same direction.
Climate is an average of the weather events that occur over a number of decades. How many decades? One, two, ten, twenty, fifty? There's no scientifically precise definition, and that's part of the problem.
That's beside the point, and it's not a problem. It can actually be helpful for understanding a phenomenon or do exactly the opposite if the wrong choice is made. We're not defining whether a year or a decade or more decades can be linked to the definition of Climate. But when the trend shows that e.g. the last decades
all show
subsequent increases, we can say that the trend is increasing. One could also have used a moving average or other statistical process.
Why use a fixed period such as a decade in the first place? Well, for one it smooths out the effect of outliers, thus making patterns more easily visible. Another thing is that a given fixed period can amplify cycles (due to auto-correlation) which may help with better understanding of the phenomenon that's being studied. We may, or may not, want that correlation to happen, depending on how useful that is for the phenomenon we're describing. Nothing to do with conspiracy theories of governments hiding stuff, but noise removal just like we do with long exposures with low signal, to improve the S/N ratio.
*** Small practical example ***
We have a long-standing tradition in our country (described in poems back in 1749, now a formally organized event since 1909), and that is an organized trip that visits 11 cities in the north of our country during one day, but it is only possibly to do during severe winters because the trip (the eleven-city run) is done on ice skates along the almost 200 km stretch of frozen-over canals and waterways that connect those cities.
The years that the trip was held on ice that was thick enough to support the weight of the crowds (upto 10,000 skaters and cheering crowds with checkpoints, music bands, and stands with hot beverages along the stretch) were:
1909, 1912, 1917, 1929, 1933, 1940, 1941, 1942, 1947, 1954, 1956, 1963, 1985, 1986, 1997, and not possible since then.
While too short to describe a multi-century trend, there are 2 interesting observations.
1. It is becoming increasingly rare, which would correlate with a global trend of increasing average temperature,
2. There seems to be kind of a correlation with the 11-year solar sun-spot activity cycle, which is recognized by scientists to show up on local scale phenomenae in many places around the world, but not at a global scale when taken together.
So using an 11 year period may locally introduce noisy data that distracts from the underlying trend, and that are the insights that scientists may stumble upon, and have to discuss, and agree on how to tackle the distractions.
Not even the best scientists can do an excellent job in this respect because of the absence of reliable data. This is why the final draft of the 'Working Group I' submission to the IPCC fifth assessment report specifically stated that there was low confidence in any increase in the frequency and severity of extreme weather events, due to a lack of data.
You seem to have difficulty in understanding how such a document evolves before being published. Different members contribute sections to such a document, as a kind of discussion points. The group members then try and find consensus from the larger groups until a relatively stable agreement is reached after which the final report can be published. It's similar to the Scientific method, which usually starts with a hypothesis, which is then under peer review either accepted or rejected. The final document is not a version that is falsified to please governments, but the generally accepted version based on the available data at the time. Sometimes the underlying data is somewhat modified versus earlier reports, because new/additional/more accurate data is available (because advances in technology make new analysis possible).
I'm still waiting to hear from Bart whether some of the findings in the Working Group I submission to the IPCC have been censored for political purposes.
Bart, where art thou? 
Besides this post, I don't see much reason having to keep disproving your conspiracy theories, because they are a bit of an off-topic distraction if they continue too long. You have your mind made up, fine. The large majority of Scientists around the world do not agree with you, and I know who to give more credit.
There is one more observation to be made that may bring us a bit more back on topic.
There is a large audience, particularly in the USA, that is skeptical of science in general. This phenomenon would be worth a study by itself, although the outcome would probably be distrusted

What populists like Trump/Putin/Erdogan/etc. do, is similar. They claim (despite objective observation) it is false news, it's dishonest media, it someone else, and even inject Alternative facts (known falsehoods) into their responses. That is all done in order to make people doubt objective observations (could there be another explanation, is the earth flat after all?), and create enough confusion to distract from the real issue. It's all very transparent, but the sheeple fall for it, so it's effective to create an outside enemy, and have the supporters gather behind their visionary leader, the emperor without clothes.
I for one try to not fall for such tactics, but I will try to expose them for what they actually are, in the hope that some people will wake up from their state of cognitive dissonance.
Conspiracy theories can make nice entertainment, but this topic's subject is too serious, and I try to avoid too much (deliberate) distraction.
Cheers,
Bart
