Gegner der #Maßnahmen gegen den #Klimawandel führen oft an, dass #klimaforscher nicht das #Wetter #vorhersagen können und mit #Modell|en arbeiten, die nur das vorhersagen, was reingesteckt wurde.

Unfug.

Um die #Entwicklung der #Temperatur vorherzusagen, muss ich die #KeelingKurve extrapolieren und den #CO2 Gehalt mit der #Arrhenius #Daumenregel in eine Temperatur umrechnen. Die #Magnusformel sagt dann, wie sich die #Luftfeuchte verhält.

Ein PC, ein paar Zeilen R und fertig.
Nix große Modelle.

Nothing about global warming is new

Svante #Arrhenius hypothesized burning carbon would create a "greenhouse effect" in 1896

What's new?

The different ways we obfuscate, deny, and excuse every reason to stop wrecking our environment

3 hours away from play testing #Arrhenius over Zoom for the third time. Looking forward to tossing these poor lost dorric scientists further into the Ice Age of the year 100,000.

@jimstewartson Back in the days #eugenics thinking was very widespread among the intelligentsia. Like Svante #Arrhenius of greenhouse effect fame/notoriety (and much else!) also dabbled in it. People hadn't yet seen where the Nazis would take the idea, delegitimizing it forever.

Heading off to run my first ever in-person game of #Arrhenius, the #ttrpg I've been writing for the last 3 years. Everything before now has been with friends via Zoom or Discord.

Tonight, I'm playtesting it with 5 total strangers. Wish me luck! I hope they enjoy it! 😬

#GM Tip: I like to put together videos to start off my #ttrpg games when I can. Something that acts as a mood setter, a recap of previous session's events, and it also sets a firm start to the table's proceedings.

The game I'm writing, #Arrhenius, is beginning its first in-person playtest this Friday. This is the video I put together as an intro for the players. The amazing music is called "The Colossus" by my buddy @SamHulick. Thanks again, Sam!

"Our descendants would live happier lives “under a warmer sky.” The prospect was, in any event, distant; doubling atmospheric CO2 would, he reckoned, take humanity three thousand years.

It’s easy now to poke fun at #Arrhenius. The doubling threshold could be reached within decades, and the results are apt to be disastrous. But who among us is any different? Here we all are, watching things fall apart. And yet, deep down, we don’t believe it."

Last Friday night, I did the first playtest of #Arrhenius #ttrpg with total strangers. They really enjoyed it!

We did a Session 0 and just made characters. However, part of the character creation process for Arrhenius is called a "Tuning Session." It's a little micro-backstory adventure that we use to see where the player is instinctively viewing the character's strengths and weaknesses. Based on that, we then assign the Stat scores they've rolled.

On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground

#Arrhenius’s paper is the first to quantify the contribution of #CarbonDioxide to the #GreenhouseEffect and to speculate about whether variations in the atmospheric concentration of carbon dioxide have contributed to long-term variations in climate.

April 1896
