The Biggest Science Story of the Week

newtboy says...

*doublepromote someone else finally noticing global dimming as a significant factor in global warming.

Global dimming from excess sulfur dioxide may be responsible for cutting the current excess anthropogenic heat in the system by between 15% to 50% depending on the study.
https://www.cnbc.com/2022/10/13/what-is-solar-geoengineering-sunlight-reflection-risks-and-benefits.html
What this means is, if we stop polluting tomorrow, the CO2 and other greenhouse gases will continue to warm us at the same rate for decades to centuries, but the sulfur dioxide that has blocked between .25 to 2 degrees Celsius temperature rise will be gone almost immediately, and a significant sudden rise in temp will be the result kicking off or feeding more feedback loops.

While it may seem he’s onto some global warming solution…just put more sulfur dioxide into the atmosphere…that ignores the lower growth rates and lost solar production it causes by deflecting a significant percentage of sunlight, both adding to net CO2 added to the system.
The incredibly scary part is the whitehouse and other international governments are actively researching ways to inject sulfur dioxide into the upper atmosphere despite knowing it has so many issues.

There’s no easy fix.

The Amazon’s Boiling River Kills Anything That Enters

"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.

Vox: Why America still uses Fahrenheit

KimzSendai says...

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.

Why Japan has so many vending machines

SDGundamX says...

Waaaaah?

This video gets so many things wrong it is truly cringe-worthy.

The country has been covered by vending machines since the 1960s--long before there were problems with an aging population and birthrates. The primary reason for vending machines being installed everywhere is, surprise, convenience! Who wants to go to the store and stand in line to buy a drink when you can just go downstairs from your apartment and grab one from outside your front door?

Another thing to consider is that Japan late at night basically completely shuts down--even in major cities like Tokyo the trains stop running around 1AM or so and won't start again until 5AM. Nowadays their are 24-hour convenient stores on practically every other urban street corner but back when vending machines first started getting installed nothing was open late besides bars. If you caught the last train home from work and wanted to buy a coke or something on your walk back from the station you were SOL. Vending machines helped solve that problem.

Which brings us to another point--VERY few Japanese people in urban areas commute by car. Mass transit is fast and efficient and a huge number of people just walk/bike everywhere. Since there is so much foot traffic vending machines make total sense, especially in the summer when temperatures are going to rise into the mid-90s (30+ degrees Celsius) with high humidity and people who are walking/biking are going to get thirsty pretty damn quick.

Another thing he gets wrong is that retailers are not the ones primarily profiting off of vending machines: land owners are. Either they purchase and stock the machines themselves (thereby keeping all the profits) or they make a contract with the retail company in which the company stocks and services the machine but compensates the landowner for use of the space.

Oh, almost forgot something not mentioned in the video--the low crime rates. Another reason for the proliferation of vending machines is that whoever puts them out can be reasonably sure they won't be damaged, defaced, or robbed.

Finally, while he is right that credit cards are not as big here as in, say, the U.S., e-money is huge. And all of the newer vending machines produced in the last few years will take either cash or e-money, such as Suica or Pasmo cards.

By the way, all of this information that I've posted here is available from a simple Google search and there have actually been several articles written on vending machines in Japan over the last couple of years. It's like this guy just came over here and tried to guess why there were so many vending machines around....

The Paris Accord: What is it? And What Does it All Mean?

Diogenes says...

I'm torn by our pulling out of Paris. I think it's critical that we all cooperate to reduce our Co2 emissions. But I also understand that at least what China offered (not) to do is the single biggest factor in our future success (failure).

Their "reductions" are tied to points of GDP compared to 2005 levels, meaning that they can either reduce their emissions, or grow their economy faster than their emissions grow. The latter is what is happening.

Their contribution is to try to have their reliance on coal "peak" by or prior to 2030. At the moment, they are emitting over 30% of the world's Co2, with the US at about 17%. But even when and if China's Co2 emissions peak, they almost certainly won't fall...they will plateau. As we speak, China is building dozens of new coal-fired power plants...and these new plants, along with those already built, have life spans of at least 50 years. So when you hear talk of China's already reducing their emissions, they aren't speaking of real reductions, rather lowered percentages as a ratio of growing GDP. For example, China emitted over 5,800,000 kilotons of Co2 in 2005, and 10,600,000 kilotons in 2015. Yet China's nominal GDP was only US$2.3 trillion in 2005, and a whopping US$11.1 trillion in 2015. So as a ratio of GDP, China's emissions appear to have decreased. The opposite is true, and they'll continue this farce for as long as possible. Now, some will answer with things such as:

A. But America pollutes more per capita!
B. But China deserves to have a per capita GDP that rivals that of the US!
C. You should be comparing GDP per capita or PPP!

To which I answer...our planet's climate and environments don't give a damn about these abstractions. What matters is the TOTAL amount of greenhouse gases being emitted.

So, I guess we won't keep warming under two degrees Celsius. Because it's more important that China's per capita GDP of about US$8,000 grows to match the US$56,000 of the US. In effect, if populations stayed the same, and the US economy stagnated...we'd need to wait for China's nominal GDP to grow to US$77.7 trillion compared to the US's $17 trillion.

Let me just add that if China were allowed to grow that powerful, polluting all the while, then the free nations of our planet would have graver problems than climate change.

You may think that China is a poor country without the current means to effect a major transition. To which I'll answer that their government and state-run corporations could stop buying foreign businesses and real estate, as well as not building more missiles, planes, rockets, blue-water navies, and man-made islands...and perhaps put those funds toward an honest shift toward green energy.

What the Fahrenheit?

Bill Nye: You Can’t Ignore Facts Forever

Trancecoach says...

@newtboy @ChaosEngine

From the WSJ:

"The U.N. no longer claims that there will be dangerous or rapid climate change in the next two decades. Last September, between the second and final draft of its fifth assessment report, the U.N.'s Intergovernmental Panel on Climate Change quietly downgraded the warming it expected in the 30 years following 1995, to about 0.5 degrees Celsius from 0.7 (or, in Fahrenheit, to about 0.9 degrees, from 1.3).

"Even that is likely to be too high. The climate-research establishment has finally admitted openly what skeptic scientists have been saying for nearly a decade: Global warming has stopped since shortly before this century began."

The usual to get around paywall.

How to de-ice your car, Polish style

BoneRemake says...

It only gets colder the higher up you go... which seems kind of counter as to what thermodynamics teaches you.

My car is plugged in, keeps the oil in a fluidic runny state, people also plug their battery's into a battery warmer, Batteries use a chemical reaction and when it is -25 Celsius.. batteries do not work so well- LIKE MINE ! I disconnect it and just bring it inside.

I heard some regions of Canada plug in their cars to electrical outlets to help protect them overnight.

Do you guys do that in Alaska?

GoPro Pimping: Where's the camera?

BicycleRepairMan says...

"At least someone found something to do that's fun when it's freezing cold outside."

He's Norwegian, and we are experiencing the mildest winter in recent memory right now, its about +6 Celsius here now. in January. In Norway. Thats absolutely mental for this place. There is no snow. It rains, its foggy and shitty all over the place. Usually its -10 to -15 and white snow everywhere by now, but not this year.
