Watching the Three Gorges Dam as China Floods

UPDATE: Scroll through the Twitter thread #ChinaFloods

See the spectacular and heart-wrenching footage of raging torrents. I have never seen water move on that scale. Why isn’t this on the news?

But NO evacuation #Hefei #Anhui? Like demons in the night #4thReichChina #Chinazi #Xitler #CCP blew up dams & intentionally flooded & killed a city of 60 million PEOPLE to try save richer more important areas. #ChinaFloods #ChinaTruth #HumanitarianCrisis #EnvironmentalDisaster pic.twitter.com/My8pqbZHUY

There is remarkable footage coming out of flooding in China #Chinafloods.

I can’t verify the authenticity, or dates, but it seems likely that terrible things are happening in China. There are shots of levees being deliberately broken to allow waters to flood fields to take the pressure off the dams, and some say the flooding is done without warning and even at night. One shot shows a barge with people on board crashing into bridge pillar and breaking apart. Lord help them. There are reports that the grain crops have been hit hard. “Agriculture wiped out”. There are multiple other reports of thousands going without food or water, with no attempts to rescue them. And there are scores of videos [...]

Watching the Three Gorges Dam

Eyes are still on the Three Gorges Dam as a rare flooding event spreads across Asia. Bridges that have stood for 500 years have succumbed.

Pity the poor people of Wuhan, the flood waters released from the Three Gorges Dam have arrived. That dam and all upstream dams have opened the flood gates, and cities as far downstream as Wuhan are flooding.

According to the South China Morning Post, 19,380,000 people have been affected by flooding across China as of July 3rd. Chriss Street says “a record 16.8 inches falling between Sunday and Monday morning, and inflows running at 40 acre-feet per second after, CMA on July 4 issued an 80-percent risk of thundershowers for each of the next 11 days.”

Check out the brief shot of the flood in a supermarket.

Apparently the dam is so large and heavy it even ranks in discussions of seismic potential – namely that some people are concerned the weight of the water may trigger earthquakes.

The “word on the street” according to Gravitasis that Chinese people are wondering if the flooding water released from is convenient for the CCP government [...]

A history of droughts and flooding rains from 1782 – 1865 in Australia

Here’s one for all the history-deniers from 1885

Mr N Bartley understood Australias climate 134 years ago better than some climate scientists appear to now.

After the fire came the floods, Feb 2020.

Even then Australia already had a century-long rolling cycle of floods, fires and droughts. One natural disaster after another back when CO2 levels were perfect.

These go back to the earliest dates of European settlement. Wherever Captain Flinders landed in 1782 — 1792 he found “found traces of drought and bush fires invariably”. In 1839, the drought was so bad that fish “putrefied” in the big Murrumbidgee River even though there was not one coal fired power plant on Earth.

The author laments that the droughts “become forgotten in the flood intervals.”

In the modern Wifi era humans can forget even faster.

Below is my summary list of the events described in the story.

Below that, the full letter. From The Queenslander, Sept 19th, 1885.

*Since Captain Flinders was born in 1774 I assume those dates were wrong and he wasn’t commanding a ship when he was 8 years old. Any other suggestions welcome.(thanks Gee Aye, SteveD, James West and Peter Fitzroy)

(1795 onwards?)* [...]

Whole suburbs flooded after exhaustive expert flood modelling says they won’t

Another triumph of modeling

In 2014, Townsville City Council launched a detailed flood mapping service.

The maps will allow people to search individual properties to find out the risk of it being inundated during a one-in-100-year flood event.

Five years later and they’re publishing inundation maps. Sadly, new suburbs were built with the wrong expectations.

Townsville flood maps reviewed as more homes go under

Jared Owens and Charlie Peel The Australian

Townsville City Council’s spokeswoman said last night the model, which was based on expert modelling of different scenarios, was overwhelmed by an “unprecedented” monsoonal trough …

Local Government Associa­tion of Queensland chief executive Greg Hallam said Towns­ville’s flood maps relied on “exhaustive modelling of every possible scenario”, looking at variable­s such as rainfall and artificia­l structures.

“We’re not God. We don’t have supreme knowledge. We only have the best science, the best knowledge we can have,” he said. “We now know with the (dam) gates fully open … what will flood and what won’t, so there will be a new set of flood maps prod­uced out of this event.”

If we had better climate models, perhaps we might [...]

Townsville floods again: 1881, 1892, 1946 and 1953. It’d be climate change if it stopped flooding

After epic flooding in Townsville, witchdoctors are blaming climate change.

Queensland’s recent extreme weather – bushfires, heatwaves, coral bleaching, drought, Cyclone Penny, Townsville’s floods – showed Queensland is clearly experiencing climate change, Professor Ian Lowe said.

Thus spake the Druid of Runes waving a bunch of multifactor complex processes that have been happening forever, can’t be predicted and only have scary trends if you draw short graphs with no error bars. Verily we see doom, doth payth my grant, or whatever it is that keeps Prof Ian Lowe going. He is allegedly in the Queensland Climate Advisory Council (QCAC) — an organization so successful its only existence on the internet appears to be a sidebar on page 15 of a government PDF. But whoever they are, they’re experts, trust us, that the media doesn’t need to ask for an alternate opinion.

Wouldn’t you know it though, floods seem to happen quite a lot in Townsville

This is not to say that the current floods are not serious but just that Townsville is a floody kind of place. It’d be climate change if things stopped flooding in Townsville.

In the last ten days Townsville has had 600mm [...]

Global warming means a global fall in wildfires

Strangely, despite NASA Giss “discovering” that the world has heated a lot since 1998, fires have declined.

Apparently increasing our CO2 emissions means less fires. Tell the world.

Figure 2. Wildfire occurrence (a) and corresponding area burnt (b) in the European Mediterranean region for the period 1980 – 2010. Source: San-Miguel-Ayanz et al. [37].

This new paper points out that the perception is that fires are worse than they have ever been, but that this is simply not true, not in the last thirty years, and not in the last few hundred either. It also documents how much money and effort we put into suppressing almost all fires and that this is in contrast to tens of thousands of years where humans used fire as a tool. Suppressing fires is getting increasingly expensive and sometimes costs lives as well.

Putting things in perspective. We spend a lot of money to avoid death and damage by fire, yet earthquakes kill 700 times as many people and floods kill 1,800 times as many people. There is something primal about fire that we feel driven to stop.
