excluding 'now' from a data set is unorthodox to put it nicely L2
let me give you another example of what that technique can do to the truth.
yet, it has now been 40 years since Richmond last won a premiership (2017, 2019 excepted)
I know this is pointless, buts I make the point for the benefit of the primary school aged kids who might be reading, thinking ' hmmmm L2 may have a point there'.
under many, increasingly vindicated, climate change models,
rainfall doesn't necessarily decline, its temporal and spacial distribution changes. It falls in different places or different times boys and girls.
where I live, for example, gets about 2000mm annually, historically with a predictable wet and dry season.
As the climate changed, we got a 1 in 100 year flood followed by a 1 in 100 year drought.
so in the last 5 years, we still got our historical 10 metres of rain, except distributed in a fashion which makes it very expensive and tough to try run a business, keep tourists happy, grow food, preserve infrastructure, catch and store water, conduct civil works, manage natural resources etc etc etc etc (the list is quite long kids, just google IPCC warnings and predictions, and what the best brains in the known universe said will happen, is happening. Oh, and kids, if you grow up to be a statistician and are set the assignment about power and integrity of data representation, it would be judicious to review L2's posts on this thread as your starting point on how data can be represented without any integrity or power)
As you lot would repeat every time I'd rev you up by saying how cold it was, "weather is not climate". Likewise, one year of record low rainfall is not climate or climate change. If we get another giant +IOD in 2020, bump this post and demand a response!
As for "1 in 100", I'm still waiting for the 1-in-100-years storm the BoM promised us a while back.
Gotta go, we're about to be hit by a terrifying thunderstorm of biblical proportions, complete with 5-15 mm of rain. Someone has to man the panic stations!
