Personal sacrifice to fly in coach lol.

Anyway flying contributes about 2.5%, global shipping about 3%.

The easiest way to make an impact is to reduce emissions from electricity and heat production. Over 40% comes from electricity production world wide, and all because of fossil fuels. Cars/Trucks are next.

We live in a world where produce and meat get shipped across the world for processing, then shipped back to where they came from to sell. Next to shipping workers over to harvest the food. Even if you buy local, who knows where it has all been in between...

So buy directly from the farm? Dunno if that's more efficient. I currently do groceries 3 times a month, every 10 days, 2 minute drive away. Gathering stuff from local food stands would involve a lot of driving.

Problem is, transportation is simply way too cheap for the impact it has. However current civilization is build on this cheap transportation :/

And a good way to kill people is to increase CO₂ emissions

In earths history there are episodes of rapid increase of CO₂ followed by a dropoff. It surely killed some species on the way.

The idea that the atmosphere stays the same is pretty ridiculous, we had environments with such oxygen that allowed spiders to grow to the size of dogs and centipedes so big they'd eat a cow. 

The funny thing is that this is basically “us” acting on our basic animal instincts. It’s no different than other predators stealing territory from each other. We just have a much more destructive way of doing so. Can’t escape nature I guess.

Discovering a way to use nuclear fusion as a sustainable power source by the way would solve pretty much everything. Everyone who’s played SimCity knows this.

There's also the contributing factor of 'waste heat'

Dunno if that claim is accurate but Nuclear Fusion won't solve that, only make it worse.

And the warmer it gets, the more air conditioning, the more waste heat produced.

Heating in winter also contributes of course but that's getting less and less. It's almost November in Southern Ontario and still no real need for heating.

Ever played SimEarth? You can simulate your own climates.

I made an oxygen rich world with perpetual fire. A ring of fire sweeping around the planet without ever stopping. Stuff growing back fast enough for the next lap. I made a circular land mass around the equator to get that going.

I wonder what forest fires were like when oxygen was that high in the past! (35% 300 million years ago, currently 21%)

I'll bet the Dimetrodon were able to gamble all night long at 35%.

Yep, that's why I believe nuvlear winter won't be as bad as they say and the dust cloud won't enter the stratosphere, we had oxygen that would support massive fires as well as super volcanoes in the past. 

I'd like to use that simulator and see at what point a hurricane could become self sustaining like the ones on Saturn and Jupiter. I wonder are we far off from a never ending storm taking over and has it happened in the past. 

Flash Fiction Story: The Plight of a Working Class Man
By Jumpin

Can you imagine those people who work in land mine factories?

I mean… wouldn’t that be the worst job? Not just because of the fumes of methyl trinitrobenzene, but because of ethical concerns. Your product kills people… like cigarettes except worse, because it blows arms and legs off. There are a major charity organizations that exist because of your product. And second hand smoke is a slow killer, but your product…. Sheesh! You would be the biggest fucking asshole in your neighbourhood:
“This is a fine cocktail party. So… you all look successful. What do you all do?”

“I’m a janitor and I keep the floors, walls, and piss stalls clean.”

“I’m a special doctor who chisels chins, plumps body parts, and is on registered sex offenders list.”

“Oh yeah? I make land mines in a factory. Princess Diana fought to close us down… so I have a joke about her. Why did Princess Diana cross the road????? Because she wasn’t wearing a seatbelt.”

No one laughs, and the sex offender looks disgusted at the mine factory worker.

And these are the problems the working class has to put up with every day!

I've played SimEarth oh so long ago, so I have only faint memory of it (I played SimLife way more) - do you remember, can you tidally lock the planet? I'm doing some worldbuidling at the moment for next campaign, so would love to get my hands on something that can at least try to simulate that.
