Stewgreen. Well you learn something new every day, even in areas where you are supposed to be expert (remember I specialized in evaporite deposits). I refreshed my memory of Atacama humidies here:
https://www.worldweatheronline.com/atacama-weather-averages/atacama/cl.aspx
I was unaware of your Australian example, but note its a calculated RH, not a measured one.
The reason for my adamancy is that I was interested in the formation of certain evaporites that will dissolve in water they extract from the atmosphere. These minerals were deposited during the Cretaceous in the proto-Atlantic rift valley. They therefore required extraordinarily low atmospheric humidites to create the necessary super hypersaline brines and never could have been exposed to the atmosphere. They have never formed in any present-day deserts. All parts of the present-day Earth are too humid for them to form.

Fracking protesters are ultimately protesting against possible damage to local humans and local economy.
But their harassment style protesting does damage the lives of locals and the economy.
Is there an underground aquifer which is unusable due to fracking.?

People often say close to zero
"Maria Elena South (Chile), the driest place on the Earth in the Atacama. MES is dry as Mars and has a mean atmospheric Relative Humidity (RH) of 17.3%. It has a soil RH at 1m depth of 14%"
With close to zero humidity, the Atacama is one of the most arid places in the world, "
"The Atacama Desert in Chile, which has virtually zero precipitation or humidity"
"The world's lowest recorded relative humidity value occurred at Coober Pedy in the South Australia desert when the temperature was 93 degrees and the dew point was minus 21 degrees producing a relative humidity of 1 percent.16 Dec 2011

Stewgreen. I hate to correct you about the humidity of the most extreme parts of the Atacama Desert but nowhere on Earth has 0% humidity (although it might feel like it) when I have no direct experience of the central desert area in Chile. I have only visited the Peruvian coastal area where there are fogs. I believe in the driest parts, relative humidity can get down to around 35% - definitely prune making weather.

We know where that one is going
tricky blogpost
\\Google is asking for your help to spot fake news results.
On Tuesday, Google will have new feedback tools in its search results so users can flag content that appears to be false or misleading. (Facebook launched similar tools earlier this year ...) This will help teach Google's search algorithms to weed out hoaxes and, in theory, keep them buried in search results.
**Google also says its algorithms have now been trained to demote "low quality" content based on signals like whether the information comes from an "authoritative" page.//**

Caliche - that was the word used for the top soil of the desert when I worked in the Nitrate mine in the Atacama
zero % daytime humidity

Stewgreen. Interesting gardening predictions, but would have to see if they are based on projected trends or climate change model fantasies. We in Eastern England already live in semi-desert rainfall conditions (25 inches or less per year) and the only thing that saves us is that rainfall is distributed over the whole year. What may happen in the near future is that rainfall may become more seasonal, being concentrated in the winter with droughts in the summer. This would return us to conditions prevalent during past interglacials when carbonates accumulated in our soils (calcrete or caliche) something currently not happening. Is a projected 5 degree temperature increase even reasonable? I am, however, prepared with a largely gravel garden in the back, and brickweave in the front!

The Westminster Environmental Audit Committee have squeezed out a "devolpement" report - months in the making (2 years actually).
The foundation for all the hundreds (thousands?) of hours work put in ...? Yes, The Global Goals - the obvious intent of their work being to gold plate those goals.
The Government should start a national conversation about implementing the Goals, working with the BBC and other national media, and provide the public with ways to get involved. This could take place as part of Red Nose Day and Comic Relief, and link with charities working in the UK and overseas..
Your taxes at work - we're doomed.

Shukman (BBC News) has found a woman who has been monitoring ONE oak tree for 50 years. Based on this, he has determined that AGW has moved the seasons forward by two weeks and that AGW will screw up our UK gardens. I guess he must have been jealous of Mann's Yamal tree.
I wonder if he is old enough to survive the next 20 years - and realise how cold it's going to be. Shukman in his dotage will still blame it on 'carbon'.
