And then that tribe will drink from some source with just a few too many heavy metals / radioactive isotopes in it and the last of humanity will go poof as they poo poo rivers of blood and die.

Boom, the circle of life will have finally consumed itself.

i get depressed reading in detail can someone see if they mention how long they estimate the whole scenario 1 ->2->3 progression is likely to take?

Not that I see. But, → assuming worst case ←, #3 would start pre-2100.

With regards to #1, projections generally top out around 4.5C by 2100.

With regards to #2, they're using these feedbacks:


Some of those would be at least like 50 years out. But since #1 puts us at 4.5C by 2100 by itself, this can only serve to accelerate that.

With regards to #3, no idea. On geologic timescale, it counts as 'immediate.' But on human timescales, no idea.

Here's a great article about this: A World Without Clouds

Guys. Guys. Also, hypothetically, girls.

The near end of the mitigation curve is still attainable. Get Bernie and a majority in senate in 2020 and do untold WH40K violence on the superrich and a sustainable civilization with a recognizable quality of life could be realized. It sounds crazy to type out, and most of us are really lazy and complacent and greedy so the probability of it happening is really low, but it is technically one potential future path we could, with sufficient collective action, still take.

Yes. Even now.

Right at this moment yes.

For at least several many moments more this post is possibly still true 3/1-2X/201..9

The very question indicates that the world has already ended. Feelings of unreality or uncertainty are symptoms of trauma. When you’re in a car crash, you wonder whether it’s really happening… The pain of all kinds comes later. “Has global warming really started yet?” is a sign that it has already started, a bit like “I wonder when this acid is really going to kick in.”

Your intuition is correct: this is a nightmare. Isn’t that a relief and a fantastic challenge?

12C by 2100 is lunacy and is a hilariously rash extrapolation of a model showing stratocumulus dissipation as an eddy at local scale.

The loss of stratocumulus didn't happen at 12C, it happened at 4 - 5C with 1200 ppm CO2. The extra warming to 12C resulted from the loss of the clouds.

Extrapolating the model from 5 km by 5 km to the entire globe is obviously fraught with problems, not the least considering their model kept currents and wind patterns constant. The loss of cloud cover needs to be better modeled to improve predictions, but this does point to another feedback mechanism we weren't able to properly account for.

Here's a pdf of the actual paper if you want to read it.

Ideally the city is walkable and has decent public transport in the fantasy scenario and does more to curb emissions than some of the other fantasy in that article. Also didn't Marx like cities because they tend to cause Solidarity or something.

Word. It's a really good read and is a great example of the kind of localized chaotic phenomena that lower resolution global models cannot feasibly reproduce.

Atmospheric dynamics are definitely where the big lurking feedbacks may be. It's really hard to draw any conclusions about mesoscale behavior in previous climates and it's really hard to model in ways that we can generalize across time and space.

Few pathways to an acceptable climate future without immediate action

quote:

A new comprehensive study of climate change has painted over 5 million pictures of humanity's potential future, and few foretell an Earth that has not severely warmed. But with immediate action and some luck, there are pathways to a tolerable climate future, according to a research team led by Tufts University.
...
The massive analysis shows that meeting that target is exceptionally difficult in all but the most optimistic climate scenarios. One pathway is to immediately and aggressively pursue carbon-neutral energy production by 2030 and hope that the atmosphere's sensitivity to carbon emissions is relatively low, according to the study. If climate sensitivity is not low, the window to a tolerable future narrows and in some scenarios, may already be closed.

They're poo poo. They have a useful lifespan of 25 years, the engineering flaws with them are massive and paradoxically getting worse, and after you factor in repeated major component replacement they almost never pay off the inherent carbon cost of manufacturing and running the fuckers. Nobody in the industry gives a flying gently caress beyond the paycheck, myself included. Nobody.

You're full of poo poo, both of these claims are extremely wrong. I have never seen a single study that has claimed anything even remotely over a year of energy or emission amortization for either on or offshore wind. After year 1 they run emission and energy surpluses, including all costs over the entire life cycle, including all maintenance and Replacements. What are you even talking about?

Also I Personally know at least two dozen people in the renewable industry, including a good number of wind engineers and planners, and they all care a good amount about the climate and do it for idealiological reasons. Myself included.
