For a while in history, there have been some doctors who would suggest treating a fever with an icy bath. You know, to bring the fever down. What we know now is that raising the body's temperature actually helps the immune system fight off infections. So, if someone has a fever treating the symptom (hot) with the opposite (cold) is usually terrible idea.

What do we do at home when we have a fever? Warm soup or tea. This makes it easier for the body to keep its temperature up. Treating like with like.

Temperature activated... because airframes NEVER go through extreme changes in temperature...

Can we really call it transparent aluminum? I mean, then its also solid oxygen! at room temperature!

Red Transparent Aluminium! aka Ruby
Blue Transparent Aluminium! aka Sapphire

AMAGAD. WHAT IS THIS ON MY KITCHEN TABLE? TRANSPARENT SODIUM!!?!??!?!?!1

Another thing to keep in mind is that different forms of elements and chemicals have very different properties.

Pure elemental liquid mercury is pretty cool stuff. Lots of people (myself included) can remember playing with elemental mercury in their bare hands in chemistry classes, etc., and even that sort of cavalier use basically never resulted in cases of mercury poisoning.

In sheer statistical terms, I gather that it is relatively safe to have pure liquid mercury directly on your skin -- cupped in your hands, say -- for short to medium periods of time. Open wounds, even small ones, can make that significantly worse. Even ingesting elemental mercury generally doesn't result in too much absorption into the body, but it remains a terrible idea. Evaporation of elemental mercury even at room temperature can lead to inhalation of mercury vapor, which is drastically more dangerous. So, ventilation and environmental controls are quite important.

This organic mercury sounds like terribly nasty stuff, but fortunately people are very unlikely to be exposed to it outside of a lab or if you are a scientist who is intentionally synthesizing it.

I think it is kind of a shame that those high school chemistry type sessions of messing around with elemental mercury are pretty much gone today. On the other hand, even though the risks are lower with elemental mercury like that, the rewards aren't really all that high either. I have fun memories of messing around with the stuff, but it wasn't by any means necessary or important outside of pure academic curiosity. Better safe that sorry I guess, particularly when the extreme end of "sorry" results in horror stories like this.

I have Hyperhidrosis (fancy medical terms for excessive sweating). My palms & feet sweat like 80% of my waking hours. Even if it's just around freezing temperature you can see sweat from my palms turn into steam like you see in this video. So I hate the embarrassment (both sides) when friends/clients/new colleagues reach out for a handshake.

Nutria don't die off every winter, so the weevils are likely to be less of a problem. There was actually a small scale trial before they built the weevil greenhouses, which didn't uncover any major issues with them.

See https://features.texasmonthly.com/editorial/creature-green-lagoon/ for many more details including the lack of frost tolerance:

Still, their campaign faced a significant obstacle: Caddo’s unfortunate latitude. The bug, like the plant it craves, is tropical. Problem is, weevils are felled by frost, while salvinia can stand slightly lower temperatures. This has proven to be Caddo’s curse, said Julie Nachtrieb, a biologist who raises and studies salvinia weevils at the Lewisville Aquatic Ecosystem Research Facility, part of the U.S. Army Corps of Engineers. In places with mild or even nonexistent winters, weevils can be released a few times and then “you can walk away and let nature take its course,” she said. But at Caddo, the weevil populations must be reconstituted every spring, giving salvinia a running start.

"The hottest temperature I've measured was over 210 degrees Fahrenheit. To put that in to everyday terms is 99 degrees Celsius."

Fixed that for you.

...

(This is a really interesting phenomenon but whoever wrote the voice-over is an idiot.)

The data of the study came out of Germany, where the effects of a change in temperature are much more moderate than in many other areas. Basically, this decline is attributed mostly due to farming, the saturation of everything with pesticides, and, generally speaking, the destruction of the ecosphere. Even worse, this is in a country with comparably extensive regulation on all these matters, unlike, say, India.

As you say, this really is no bueno.

Driving past fields of rapeseed in the late '90s meant a windshield full of bugs. We used to head into the fields wearing yellow shirts just to see who can get the densest armor of bugs. Now, I can walk past the very same fields outside the town I grew up in with less than 5 bugs on a yellow shirt.

Or how about another anecdote: when I grew up, barbecue in my (grand-)parents yard meant paying attention to all the wasps, so that you don't swallow one by accident. I haven't seen a single one over several barbecues this year. Bees and bumblebees are still around, though less plentiful, but wasps are a complete no-show. Haven't seen a hornet in two years.

So much for keeping temperature rise below 2 degrees above preindustrial averages (or even the Paris 1.5 degree goal) being "safe". We're at 1.2 degrees and rising last year, and it seems like Ragnarok is upon us.
This is pretty good evidence that the anthropogenic extinction event is well under way, not something to fear might happen in a dystopian future. Both the natural food web and agriculture are dependent on insects. A 3/4 reduction is probably at or beyond the tipping point.
This business is going to get out of control, and we'll be lucky to live through it.
Fuck. We all better call up Jim Bakker for some apocalypse food buckets quick.

For everyday use Fahrenheit seems pretty handy. 100 °F is dangerously hot, 0 °F is dangerously cold, you know you have to take extra care if it gets out of that range. And a body temperature of 100 °F is the start of having a fever.

The only number you need to remember is that water freezes at 32 °F. I doubt you'd ever need to know the boiling point of water to cook.

Plus the much smaller increments are nice. °C is good if you're a sciency type and need to convert from Kelvin, but otherwise I don't see many advantages.

I've lived in the US since 2013 ... I'm OK now with instantly "translating" to miles and feet and pounds and gallons in colloquial speech (at work we all use metric because I'm in science and tech with international collaboration), but Temperature??? I'm still in Celsius and can't adapt seem to adapt.

Maybe there's no logical reason to have different systems but the reasons to have only one system are kind of thin. I am perfectly capable of using more than one system and I find that I prefer different systems for different uses. I can use imperial measurements when I build a shed and metric when I do engineering calculations. When I cook, I might use cups and tablespoons to make chili but I use grams to measure ingredients when I bake bread. And if you prefer one or the other, I can adapt. Humans are good at that. ;-)

Extend the argument and it's not logical for the world to speak more than one language. Translating between languages is a whole lot more work than translating temperature scales. We should all speak Mandarin, because it's the most spoken language in the world. But my best friend's 2 year old speaks Mandarin AND English. I suspect he'll be just fine.

Anyway, long story short, I agree we should all know how to use the metric system. That doesn't mean we all need to use it for everything.

Vaping only heats the weed to a temperature that vaporises the active chemicals without turning it to carbon, so you put far less through your lungs. They make vaporizors that use a water pipe attachment, so even the vapor gets cooled.

The Pax has different temp settings so you can get just what you want. Lower temps produce far less vapor and might leave some less volatile chemicals in the weed, hotter vaporizes more and produces a thicker hit, but ends up toasting the weed and eventually burning it. The Pax isn't designed for hash and or oils, for that I suggest looking at ineedhemp.com . They have setups for oil and herb, and offer the water pipe attachment.

Well, that's one step in the right direction that you now admit the undeniable fact that global temperatures are rising....finally.
Interesting, then what is your theory, seeing as natural cycles would have our temperatures falling right now, but since the industrial revolution they've been trending higher. You can't blame volcanos, there've been no massive volcanic releases to cause it, only minor ones that barely register.

Yes, true, the Paris accord is too little too late, that's not somehow condemnation of the idea that global climate change is man made. Only one nation even questions that, and really only <1/3 of that nation.
Did you ever watch An Inconvenient Truth....I don't think so, because it said no such thing, I think you're repeating what a talking head told you it said. He did say we would probably see obvious effects by now...and we do. He did not say we would all be dead, not even in 100 years.

Hundreds of thousands, if not millions, are not still here, they are dead of famine and wars caused by, and causing, migrating populations. Most of East Africa is in severe drought as bad or worse than Ethiopia in the 80's, just like Gore warned would be increasingly more likely due to climate change, and India and Asia are threatened with losing their main sources of water because of accelerated glacial melting.

Every group that a has money at stake are trying to influence the people / governments one way or another in their favor.

I do believe that temperatures are changing but to say man is mostly at fault -- I don't buy it. Even those promoting man made warming concede that even the Paris accord will not truly change the doomsday course we are on.

Al Gore's Inconvenient truth movie has the planet basically dead today -- but we are all here. Kind of the boy crying woof.
