    Using weather radar for meteorite detection and recovery is a thing. I did not know that.

    We are told that earth acquires about 40,000 tons of iron (plus minor others) in this way. Earthquakes and volcanic eruptions blow of some of the highest atmospheric level, but I have not seen that estimated. But these processes describe mass balance of planet. Until some rocketeer sends up really heavy stuff.

    I haven't read that yet, but weather radar was one of the tools used to help track down several pieces of rocket debris earlier this year, when Musk missed a house in my state by just 50 feet (beware of some blunders in the included graphics):

    I have understood that the vast majority are stoney, not ironey. However, humans are much more likely to notice odd looking ironey bits than random stones strewn outside. A.k.a. 'recovery bias'.

    On the temperate continents, iron chunks are about 5% of the collection. But on Antarctica, where stones also stand out as unusual on ice surfaces, iron chunks drop to just 0.4%.

    Politician Scott Pio of Virginia suggested taming sea-level rise by removing (all) ships from the sea:

    Politician Floats Removing Boats To Lower Rising Sea Levels. Would It Work? | IFLScience

    XKCD comic boss calculated 6 microns of sea level result from water displacement by 'the fleet'. It's worth knowing such things. This treatment does not emphasize goods and services provided by sea faring, including a large fraction of human nutrition, almost all international shipping. And who can forget all the navies sailing around for surely important purposes? Cruise ships and oceanographic research. Leaving this list incomplete, but dang, there are a lot of things packed into those 6 microns..

    "... this volume would be replaced in roughly 16 hours, based on current estimates of sea-level rise, ..."

    You posted this to make me ROTFLMAO:

    Except I didn’t.

    There is a serious problem that we are not generationally removed from the dark ages.

    A container cargo ship is burning off the cost near Victoria British Colombia. Could be 'meh' in terms of environmental news? But the fire started in two containers of Potassium amylxanthate. So, environmental chemistry:

    This stuff is used to separate metal ore goodies from sulfides. Both copper and nickel avidly form sulfide ores. Since both metals are important to our electro-economy (and stainless steel production), I imagine a lot of this stuff gets made and shipped around.

    It ain't rocket fuel, but obviously it burns pretty good once it gets going. No idea what 'lit the match'. No idea either how much potassi-whatchamacallit is moving around. That's the sort of thing one finds out by buying a $5000-dollar 'industry report'.

    Title:
    Recent increases in tropical cyclone precipitation extremes over the US east coast
    Link:
    Recent increases in tropical cyclone precipitation extremes over the US east coast | PNAS

    My summary - 300 years of tree rings from N and S Carolina. More late-season wood forms in years with big rain, which more or less relates to tropical cyclones. Study measures tree-ring widths, compares those with rain since 1950, and concludes what the title says. Not so many tree that old survive in study area, but, OK, yeah.

    Local news indicated that the ship carried 57 tons of that chemical across a handful of containers. A couple containers were among the 40+ that fell into stormy seas. Those that remained on the ship were the source of the fire.

    News suggested that this stuff is not only flammable, but also should not come in contact with water. Pictures sort of suggest that something low on the stack collapsed, possible leaving some broken containers on or hanging over the side of the ship.

    The fire was 'stabilized' today. A special crew will go after it tomorrow, weather permitting. The weather is an offshore 'bomb cyclone', which this morning reached the lowest barometric pressure ever recorded this close to our coast. 942mb. Claims are that it is equivalent to a Cat 3 hurricane.

    The windstream graphic at WunderMap® | Interactive Weather Map and Radar | Weather Underground was pretty revealing yesterday. It's still fairly active today too.
    ((Going to the link above, on the right vertical menu it defaults to weather stations. unclick that and scroll down to the windstream option (the map turns gray and it takes a while to load) It's possible to get almost half the planet inside the map. And moving the map around is also fun. watching the graphics go psychedelic for a few seconds.))
    There is another swirling mass to the WestNorthWest of the weather approaching the northwest coast, as well as a hurricane making landfall in Mexico today/tomorrow. If interested don't forget to check out the windstreams around Antarctica. That area doesn't seem to get much attention until temps get up into the 60's F on the continent.

    The fire appears to be out. Pictures show the damage, the great majority of containers on the ship appear unscathed:
    Fire on cargo ship off Victoria, B.C., put out, and hunt continues for 40 containers that went overboard

    Looks like round 2 is making landfall soon. Now wondering what round 3 is going to look like at the end of the week.

    Another perspective about the 1 2 3 sequence from Country Joe in the late 60's.

    "a brain barely bigger than a poppy-seed"

    Just in time for Halloween, a study on brainpower in small hunting spiders:

    Spiders are much smarter than you think | Ars Technica

    If you do not like big pictures of them, do not click link above.

    Knowable magazine presents accessible summaries from some articles published by the library-shelf-crushing Annual Reviews of X series, where X is pretty much anything at all. You could do worse in terms of reading materials :)
