Taken over from Bob have we? [biggrin]

Sorry Bob, didn't mean to cut your lunch.

I saw it this morning on my weather site and thought the info was very good.

Does bob own weather?

Quick review of the 2019 link
"" As a result of prolonged drier-than-usual weather, water storage levels at the end of May were lower than the same time last year in every capital city except for Perth. Sydney and Melbourne both reached their lowest water storage levels in nine years last month.
So, what types of weather can we expect to see around Australia during the next few months?"

[B]Result- Possibly the worst bushfires events ever widely across Australia . So good it got wikki (https://en.wikipedia.org/wiki/2019%E2%80%9320_Australian_bushfire_season)[bighmmm]




My turn I love the water

50% of the coral on the great barrier Reef is D.E.A.D. :bat::bat::bat::bat::bat:

Several of my Diving mates have said its worse in spots they dive on now. The time for cynical fools is over to late I feel.

Great Barrier Reef coral halved by bleaching, climate change, report finds - ABC News (https://www.abc.net.au/news/2020-10-14/great-barrier-reef-coral-halved-in-25-years-report-says/12766444)

Not nice to read about but there ain't nothing any of those over paid fools in all our parliaments can do to stop climate change although they will spend billions of our dollars on silly schemes trying to do so. Stopping pollution as much as possible is a different matter entirely.

Repairing rotting timber railing at work with REPLAS which is being delivered tomorrow. A recycled plastic work bench to build to try and make myself feel just that little bit better. All of my other work benches are removed timber from building and office demolitions I run past and dumpster dove with my disco roof rack making that easy[biggrin]

I did have permission each time promise so I am not a true dumpster diver

Replas is providing a significant resource from recycled plastic waste. Costing me a bit more than the free timber I have been using. Money and My mouth meet for once? Good night

Last time I looked last week Sydney was at 95% .

What a difference a few months makes Eh.
disaster narrowly averted yet again.

Wetter than usual is "The Bureau of Meteorology is forecasting above average spring rainfall for most of eastern Australia due to the potential development of La Nina, as well as warmer ocean temperatures in the eastern Indian Ocean.


Warmer conditions and above average temperatures are likely, especially in the north of Australia and the far southeast including Tasmania.


"


News that half the corals in the Great Barrier Reef have been lost in the past two decades is alarming enough, but experts say alarm at findings of dramatic coral losses is drowning out even greater concerns for survival of the entire marine ecosystem.

The Centre of Excellence for Coral Studies published findings this week that the number of corals have halved in the past twenty years, on average across the 340,000 square kilometre reef.

Its still wet on the reef. https://static.ffx.io/images/$zoom_0.393%2C$multiply_1.9339%2C$ratio_1.776846%2 C$width_1059%2C$x_95%2C$y_338/t_crop_custom/q_62%2Cf_auto/4430d4e126891d5e1a03405bafb5aafba1342dde

Wet and dead sadly

I still am a little shocked by this so excuse me for harping. After Diving around the world I have seen some underwater places destroyed that sometimes was recovered when people stopped doing stupid thing. Dynamite fishing in the Philippines is one example.


On the Great Barrier Reef fishing, tourism and huge money is going to be lost with out significant changes. Fiddling around the edges would stop the loss of one of the real wonders of the world.

Blowing up historic sites such as by ISIL which blew up World Heritage Sites in Palmyra (Syria) or Rio Tinto's Juukan Gorge blasts seem to have attracted more attention than what I feel/think is a much worse issue which needs urgent attention. In 2016 "Great Barrier Reef region -$12 billion revenues and directly support over 100,000 jobs" Why nothing may be done could be in 2018 "Coal was the highest earning export commodity for the year, accounting for $66 billion in export revenue, bolstered by improved prices and and volumes driven by demand from large Asian markets." Not sure how much of that was QLD, I doubt where the coal comes from matters really. Rant over.

Grab a snorkel and swim if your lucky enough to be near some rivers to in my preference salt water. If the lock down is backed off here in Melbourne a bit tomorrow; I am off for a paddle in my little canoe, from Warrandyte to Melbourne. Just might keep going to Williamstown assuming I can convince some one to pick me up. Have a great weekend.

Interesting to see that SE Water (Qld) have started up our desalination plant as water stocks have dropped below 60% capacity.

Most Brisbanites wouldn't even realise that we are on the brink of water restrictions .

I still cannot understand why we don't power the very expensive to run desal plant on renewable energy.

We now await whatever joys our purported weather systems are going to bring to us.

Thousands of new houses , new roads , drains and streets haven't really seen a drop of rain yet.

Could be interesting.

Weather News - Australian climate update: June 2019 (https://www.weatherzone.com.au/news/australian-climate-update-june-2019/529790)

A little deviation to our northern mates getting who are getting hammered by typhoon Molave at present. It is the fourth storm to hit the nation’s central region in less than three weeks and nine this year had me wondering is that normal. It sort of is was the answer but there is a big change which is not pleasant

The Emergency Events Database (EM-DAT) indicates that the economic damage associated with storms has been rapidly growing in Vietnam. By contrast, the fatality rate due to storm-relevant disasters has been declining in recent decades. This study investigates whether typhoon trends have affected these outcomes. Best track data from the Japan Meteorological Agency (JMA) were examined to estimate central pressure and wind speed when typhoons made landfall. From 1977 to 2017, typhoons with wind speeds above 20 knots struck the country 105 times. A statistical analysis, which defined a storm's intensity using principal component analysis (PCA), revealed that Typhoon Doksuri in 2017 was the strongest among the collection, followed by Cecil in 1985, Xangsane in 2006, and Damrey in 2017. The worst storm in history, Typhoon Linda in 1997, claimed over 3500 lives in southern Vietnam, but was only ranked 37th, demonstrating that typhoon intensity is not always the determining factor of fatalities. Moreover, the analysis of variance (ANOVA) illustrates that none of the meteorological trends such as frequency, central pressure, wind speed, or storm intensity show any significant increase or decrease over the last four decades. However, landfall frequency has risen significantly, particularly in the northernmost part of the country where two large cities, Hanoi and Hai Phong, are located. A strong correlation was found between intensity and recent economic damage (r = 0.80) based on the proposed index of positive annual landfall storm intensity (PALSI). Given all of these factors, it is reasonable to attribute the expansion of disaster-related economic damage to economic development and the fundamental volatility of typhoons.

Apologies to the Mods for the extra work with a cut and paste- My lazy side

I saw a new report about one of the Engineering Marvels of the modern world- The Hoover dam. (Lake Mead) It is the largest reservoir in the United States by volume (when it is full)

Power and water. Power and water enables the famous Las Vagas and significantly more. Food grown in the desert which was previously vast areas of desert. The river is the Colorado which is a place I saw and recall in a few US state as a bit of trivia. The river provides about 60% of the water for drinking industry and agriculture in California

My bad cut and paste post had pictures of the dam with about a foot of water remaining in it. Head lines like "The US May Be About to Declare Its First-Ever Water Shortage (https://interestingengineering.com/us-about-to-declare-its-first-water-shortage)" and "The Hoover Dam Made Life in the West Possible. Or So We Thought. (https://www.nytimes.com/2021/05/14/opinion/water-hoover-dam-climate-change.html)" grabbed my attention and while I know you can all see then I thought you might be interested in case you had not noticed. Links only if interested.

A cut an paste of the water level I hope is acceptable to share

Suspect we are used to drought, fire and floods here in Australia. Also suspect a large part of the US might not recall what the Hoover Dam has protected the down stream users of the water and power seem to be about to find out about.
