Hong Kong and southern China battle widespread flooding from record rains
https://www.bbc.co.uk/news/world-asia-china-66748239 
Weather authorities issued a "black" rainstorm signal on Thursday night, a warning triggered by rainfall exceeding 70mm an hour. The Hong Kong Observatory later reported an hourly rainfall of 158.1 millimetres, the highest since records began in 1884.

An awful lot of 'record breaking' rainfalls around the world this year.

We know that global warming increases the amount of water that can be carried in the atmosphere, and heavier rainstorms have long been forecast to be a symptom of climate change.

Coupled with the amazing bouts of heat that many places have also encountered, is this the year that the impacts of climate change take a big step up?

Looking at the Global SST's for this year and the extreme +ve anomalies I think we may be experiencing some sort of step change and these crazy SST anomalies are being reflected in far more extreme rainfall events all over the globe

No concrete evidence of causation afaik but definitely a correlation

If anything, el Nino adds a small jolt to the north Atlantic jet stream during late autumn and winter, though I do stress small. It is a curious coincidence though that slower moving patterns, bringing more longer lasting high pressure zones etc over the greater north Atlantic region have been dominant since the la Nina came into play, and this current stagnant high could be a lagged legacy of that

In Southern France, almost three weeks back now, they had a few 40c days and our friends shared that experience with us, as their property has a lot of trees, they mentioned that you could smell the leaves cooking in the heat of the sun which left a rather pungent odour on the air. it was also very evident when we first arrived on the 31st August as most of the nut trees have dried, crispy leaves which they are now shedding and the fruit trees and most noticeably their cherry, were all wilting and leaves curled. There was overnight rain on the 2nd September which seemed to briefly refresh most of the trees and plants but by the time we were leaving yesterday they were all looking a bit sad as it's been hot and dry all week again. Hopefully it will rain there on Tuesday.
One other note is that this year there has been bumper nut harvests from their hazelnuts and walnuts and all their fruit trees too. But a noticeable lack of so many wasps, in comparison to the last five years, they had a longer and colder winter earlier and a good amount of snow which may (or not) have been a contributing factor.
