Ok was getting into a simple #Gedankenexperiment. since I first heard about global warming in 1993, I have been struggling with one thing.... the differential volume of a sphere (or oblate spheroid in this case.)

using 6378 km for earths radius (NASA's Goddard Space Flight Center)

So Surface area of oceans, conservatively is:

4*pi*r^2 = 4*3.1415*6378*6378 = 511,170,000 (keeping only 4 sig figs)

The projected sea level rise by 2100 per https://www.climate.gov/news-features/understanding-climate/climate-change-global-sea-level

"on a pathway with high greenhouse gas emissions and rapid ice sheet collapse, models project that average sea level rise for the contiguous United States could be 2.2 meters (7.2 feet) by 2100 and 3.9 meters (13 feet) by 2150.2"

Now about 71% of earth is water, but for this calculation lets conservatively estimate that the connected oceans are only 65% of the surface:

The volume of ice needed to do this would be:

65(4/3*pi*r_final^3 - 4/3*pi*r_intial^3 )=0.65*(1.087874E12 - 1,086749E12) = 731,200,000 km^3

Now it is estimated that there are about 26,500,000 km^3 of ice in antarctica (if it all melts) and that is the largest deposit in the world. Greenland is also large but less than that, and all the other ice (i.e. Arctic, mountains, etc...) might be 7,000,000 km^3

So conservatively estimating that there is no more than 60,000,000 km^3 of ice in the world (most likely closer to 45-50 million cubic kilometers)

How can see levels rise 2.2 meters? you are a good solid 680,000,000 km^3 short (yes 680 million cubic kilometers short)

What am I missing. These are smart scientists I can't believe a small down #chicagoan​ would out think the best scientists in the world

From EPA.gov

The average passenger vehicle emits about 400 grams of CO2 per mile.

Work from home has ended for many due to govs pushing people back to the office. Assuming the average unnecessary commute is 2*10 miles/ day and 150 days/year, and assuming 40,000,000-80,000,000 us workers fit that bill.

Bitcoin estimated carbon

22.9 million metric tons of carbon dioxide emissions a year. (Left leaning Reuter) REALITY IS MUCH LESS.

The U.S. Energy Information Administration estimates that in 2019, the United States emitted 5,130 million metric tons of energy-related carbon dioxide, while the global emissions of energy-related carbon dioxide totaled 33,621.5 million metric tons.

Bitcoin is 0.000621 or (0.06%). Of the worlds carbon footprint, basically a rounding error. And represents $0.5T/$900T or 0.05% of the worlds wealth, another rounding error.

#Bitcoin DOMINATES THE time of WEF, SEC, TREASURY, GREENPEACE, CHASE BANK, and many many more

Just think there are 21 Bitcoin in the wild for every Porsche 911 in the wild Pretty rare

Depressing

Start here:

Read it all understand multi-sig , air-gap, multi-vender

Then look here https://bitcoin.rocks/wallets Bitcoin.rocks for a good discussion

That doesn’t look like Salina Kansas to me.

Much bigger discussion

Ok here goes:

1.think of your lightning wallet as your “bill fold” you carry only a small amount of cash(cash for the weekend, or night out), DON’T KEEP MUCH HERE, like $100 -$200 just like a bill fold, rug pull won’t affect much.

2. Think of your “software” self-custody wallet as your checking account. This could be something like “brave wallet” or coinbase wallet. But must be self custody. Keep a month or so salary here.

3.think of your hardware/cold storage as your savings account. This is your NEST EGG.

If you think that way, fees/convenience dominate the lightning wallet choice. And just like loosing your billfold (it sucks) but won’t affect your destiny.

Features/convenience dominate the “software” wallet. This wallet is self custody and keeps a month or so of working cash. Typically hooked up to an exchange for moving coin in and out, and sending to your LN wallet.

security dominates the cold storage wallet decision (e.g. multi-sig air-gap multi-vender etc… nostr:note1x9jxx7t9c8tht8t2vujcy9znte5dpyl7vt4sqnsag64guymywyksst8ayg

There will be days like that!

Yep #lnurl protocol is awesome

Governments should not have many of the rights they have seized.

Just remember only stack off the exchange. A coin in cold storage is worth two on the exchange

I’ve posted this same message 100 times!

Can’t believe #satoshi Nakamoto and I both had the same thought!

I am sure many people will be asking how can a 2000 year old book be so accurate. #markofthebeast

Adding @bitcoinrocks Still thinking a lot about this image and what causes it.

The basic answer is this is cause by two things:

1. The success of #nostr

2. The #LNURL-pay protocol.

Because of the critical importance of LNURL in introducing people to Bitcoin I thing the more important focus should be I getting people comfortable:

1. Moving money from lighting to a self custody software wallet, ann vise-versa

2. Keeping large sums in a cold-storage hardware wallet.

#phoenix wallet claims to support it, but I could not find it, or figure it out.

No good comes from Forcing or shaming people away from wos. Teaching them the risks and mitigation strategies like pulling it off each time you reach $200 will both educate people, and push/increase adoption and utilization.

#chicago #312 #bitcoinstr #photostr #photography #chicagoplebs #agriculture #industry

Was down by the chicago fed today,

Decided to #photo two statues. Interesting story on the second image.

Symbolizing agriculture and industry these two statues stood atop the chicago board of trade until #1929.

Ok full disclosure. I am no longer from Chicago. I live in Indiana.

Leaving Illinois 9 years ago was the best choice I made.

Every day during the pandemic I woke up and thanked god that I didn’t live in Illinois!

Arkansas is pretty awesome if you just want government out of your life and like nature! Been there several times and may buy a weekend getaway some day .

Texas is the best state in the union just sold my Dallas house, been down there periodically for 17 years, Am planning to go back at least in the winters more regularly.
