Reuters: Chinese Rains are “Once in a Millennium”

July 20, 2021

Dam collapse in Mongolia

Lot of that going around.

Reuters:

Large swathes of China’s central Henan province were under water on Wednesday, with its capital Zhengzhou hardest-hit after being drenched by what weather forecasters said was the highest rainfall in 1,000 years.

In Zhengzhou, a city of over 12 million on the banks of the Yellow River, 12 people have died so far amid the floods, and about 100,000 people have been evacuated to safe zones, the official Xinhua agency reported, citing the local government.

The lives of millions of people in Henan have been upended since the weekend in an unusually active rainy season that has led to the rapid rise of a number of rivers in the Yellow River basin.

Streets in a dozen cities have been flooded, while dozens of water reservoirs and dams breached warning levels.

From the evening of Saturday until late Tuesday, 617.1 millimetres (mm) (24 inches) of rain had drenched Zhengzhou – almost on par with the annual average of 640.8 mm.

The level of rainfall in Zhengzhou witnessed over the three days was one seen only “once in a thousand years”, local media cited meteorologists as saying.

Dramatic video shared on social media since Tuesday showed commuters waist-deep in murky floodwaters on a lightless subway train and an underground station turned into a large, churning pool.

    Once in a millennium until next year.

    RNZ: Climate change and recent flooding: What you need to know

    =================================================
    We “seem deaf and blind to the science and the tools and methods for planning that we have available to address these risks.

      Looking at the visualizations in the article, it reminds me that we can harness petaflops of computing to model and forecast weather and flooding, but we can’t easily deprogram hundreds of millions of propagandized people.

    we’re the rats banging the dopamine stim bar in the lab, over and over until exhaustion and collapse. Most species are not capable enough to deal with the predators, a good thing so that there’s ecological balance. But the evolutionary “advance” of a forebrain, Homo Sapiens are far too capable in growing like a cancer and vanquishing any and all other species in satisfying its endocrine lusts.

    Overshoot and crash. That’s the likely end state. Not human extinction, but a collapse of civilization and population to a fraction of today’s as fraying in the networks that we’ve intricately built and which we hardly understand any longer, take us down in an amplifying feedback. The less capable we become, the more vulnerable to that very fact. Growth and ultimate decay both have their positive differential equation terms in them.

    All the rah-rah over solar this and wind that do not change these facts, they only push the innovation button to a higher level and faster growth and faster speed towards the singularity. Unlike econo-utopians, physicists understand what a singularity does to you. You get ripped atom from atom.

      One of your better comments. Three succinct and truth-laden paragraphs.

      Not defeated until you surrender. Apart from that, agree with thee.

      I’m going to push back a bit on this. Tech and innovation* can displace more horrid costly systems. New extraction of recyclable materials to make solar panels, wind turbines, and batteries are replacing the much more damaging regime of coal, oil and gas extraction. Aesthetically unpleasing (to some humans) wind turbines replace toxic combustion products that all birds and animals breathe in.

      Having said all that, I’m not at all optimistic that we can outrun the tsunami.

      ______
      *One class of innovation that I think is underappreciated is the phase where we establish standards—for rail lines, for container shipping, for SKUs, for file formats—that reduce the inefficiency and chaos of ad hoc proprietary practices. I’m hoping that, for example, the grid will adopt a more plug-and-play approach to adding and managing components.

    China can receive much rain at times, or also severe & persistent droughts & the anthropogenic climate change crowd wants to try to blame both extremes on the trace gas, CO₂.
    Modeling of severe persistent droughts over eastern China during the last millennium

    Abstract. We use proxy data and modeled data from 1000 yr model simulations with a variety of climate forcings to examine the occurrence of severe events of persistent drought over eastern China during the last millennium and to diagnose the mechanisms. Results show that the model was able to simulate many aspects of the low-frequency (periods greater than 10 yr) variations of precipitation over eastern China during the last millennium, including most of the severe persistent droughts such as those in the 1130s, 1200s, 1350s, 1430s, 1480s, and the late 1630s–mid-1640s. These six droughts are identified both in the proxy data and in the modeled data and are consistent with each other in terms of drought intensity, duration, and spatial coverage.

      Quit with the “trace gas” bullshit. “Trace” means it’s a small percentage of the composition, not that it’s harmless or has no effect.

      Do you really want to claim that “trace” means unimportant or harmless, or are you just deliberately trying to muddy the waters.
