Winning "3 degrees" without bioweapons and aerosols?

[Lyrandon]

Has anyone been able to win "3 degrees" without use of bioweapons or aerosols? If i don't kill large part of the worlds, i just am not able to stop global warming without use of aerosols. Is there a tactic to win this scenario without being a mass murderer and without "cheating" with aerosol use to drop the temperature in the last turns?

Even with large negative emissions of -30k and a prosperous fusion powered world i could not stop, let alone drop temperature once it has hit 3 degrees without aerosols.

Dunno, but i should probably make that a HEFTY bonus objective :)

I would love some comments on this myself. I somewhat succeed, however am struggling with famine once oil runs out. I feel I need to be much more aggressive at the start in curbing emissions.

From what I understand, this scenario should preferably stablise emissions at 2.8 degrees warming. Preventing Deforestation in certain parts of the world (Latin America, America, Russia, South Africa, South Asia and damn the rest - In that order) is important.

Finally, my other mistake was caring too much about individual areas concerns rather than making it a concerted global effort.

A good strategy for me was Carbon Tax first turn, second turn, all switched to industry efficiency etc..

Does anyone have suggestions for curbing emissions and throttling and stablising emissions at 2.8?

Even more embarassing is that I am running the "earth day" scenario with the world green. The embarassment of it all.

I've tried the new green day mission (which i hink is like 3 degree, but everyone starts with "green" outlook) and without aerosols or bioweapons ended up with 700ppm+ and 3.7 degree warming. and that's considering everyone was off oil and coal for energy production (with some off gas as well) before 2070 and I had "protect forests" in about 4 regions...

The dilemma with bioweapons is killing off your paying customers... India I can probably live without, but China and Middle East are two of my best paying customers.... Africa gets developed enough to provide tobin tax, so no go...

I imagine you'd need to spam Biochar extensively, since the emissions reduction it causes would be essential. That or you can go the 'indirect' genocide route by banning coal, unconventional oil/gas, etc as early as you can get away with it to tank emissions (also probably wiping out most of the chinese). But staying in power & maintaining an income that route could prove extremely difficult.

I managed to play a game of Three Degrees where I switched all of the planet to renewables, stabilized the population at around 7 billion, had a stable economy and a global HDI of 0.93... thing is, while the temperature and atmospheric concentration were stable, they were stable at around 3.9 degrees, so I lost the scenario.

Honestly, I think artificial trees and biochar are not working as intended at the moment (there's another thread about that, but unfortunately no comment either way from the developers), which makes actually getting all the stuff out of the air impossible. I literally played the save the forests project in every region and had both biochar and artificial trees running worldwide and I still couldn't reduce atmospheric concentration...

I've just played my best 'earth-day' game so far, and still the temperatures went up too fast.

I'm at 2125, 3.2 degrees. In 1 or 2 turns solar power from space will kick in. I am spreading fusion and nano-tech around the world the next few turns. (free energy and artificial trees)
Before it's 2150, I will have negative emissions.
But it's already too late.
Arctic Methane is an unstoppable force, the icesheet of Greenland is collapsing.
It's a downward spiral.

Next time I have to play 'cap and trade' a bit earlier I think. And maybe biochar as well?

[LordMarconius]

Here's a thought... what if you started aerosoling right when it's invented, keeping the temperatures down -while- you work on emissions and the lot? Then you can turn it off and hopefully avoid the temperature skyrocketing, meaning arctic methane and such wouldn't be quite so bad. That way you'd use aerosols to just buy some time for yourself to enact various policies, rather than just to cheat the victory conditions near the end...

I'll have to try that... should be an interesting experiment.

Tried that. In GreenDay replay I invested heavily into tech and got aerosols by 2060 and 1st gen nano in 2105 with space solar launched in 2110. By 2120 fusion was discovered, but everyone was already 100% renewables and on synthetic feedstock.

China, asia, ME were all on CC&S asap too. Couldn't afford to go nuclear as in previous scenarios that ruined me...

In short, despite spamming aerosols at the end my emissions ended up at 667ppm and 2.5degrees when i launched the Space Ark in 2180... I think at one point I had 6 regions spamming with very limited effect. Droughts were awash...

Going to finish the game properly tonight by NOT launching the space ark.....

Insidently, I think India's 2nd gen Nano-medicine is bugged. I've discovered it in 2165 I think, and tried to "bring" the tech to india, but dispite all technologies being up to date, the 2nd generation nano-medicine did not show up!!! India has the worst HDI due to mortality, I was hoping to bring the tech to India to them, get HDI to 0.90 and Tobbin them to get "Tobbin all regions" award!!! :(

[finished the game without launching the space ark and ended up with 675.5ppm, 2.7degree warming. India still did not get nano-medicine]...

Would 2nd gen nanotech even affect mortality rates? Don't you mean nanomedicine?

I believe you are right! stupid me...:o
