Let's imagine we stopped all C02 production tomorrow. How long it will take for climate to start going back to "sane" measurements?
Do what you can. Live sustainably. Vote righteously. Have consideration for the future.
CNN has done so much to tarnish their reputation that my gut reaction is to distrust the information they discuss simply based on their past behavior. I think these mainstream publications are actually harming the causes they seek to highlight. It seems there are others in this thread that feel the same way.

At this point it's more a question of what we can do to prepare ourselves for the fallout, we've done our waving to the moments when we could do something as they passed by.
The real question is what will destroy the ocean's food chain first, China's overfishing, the acidity and temperature increases, or the collapse of currents. Taking bets now.

> Why does everything has to be put into the political view? BECAUSE THE FUTURE VIABILITY OF THE PLANET DEPENDS ON POLITICAL DECISIONS!
It's long past time we should stop tolerating the semantic evasion of "anything that I don't like to talk about is political and therefore out of bounds". The term itself has been stretched and mutilated to the point of absurdity, and especially any topic that has valid and exhaustive empirical research should be discussed in those terms and not shut down with a big taboo sticker slapped on it. Discussion of the stat…
What's funny is we did that exact experiment right here on HN several years ago and it went predictably tits up, since everything is political in some way, because politics TOUCHES EVERYTHING.

I believe we can solve both problems if we would focus more on the scientific method and rational thinking. Improving the educational system is the only way we get there.
Too slow, it will be decades before the people going through the education system now are in a position to effect change
Why does everything has to be put into the political view? If this ocean current is collapsing because of the current temperature anomaly, then it has happened. Nothing that any amount of CO2 limiting will do about it, because even the most optimistic IPCC projections with 100% adoption only say temperature will stabilize ~2060. That base-case is worse than the worst case considered in this paper. So this should be t…
> half the people still want to believe it isn't happening. The problem is twofold: on one side, you have those who think they can choose whether to believe in facts; on the other side, you have those who believe without understanding! As you said, we are past the return point. This is happening, and we should be doing something that actually addresses the problems caused by the ocean currents shutting down, but too…
Ah yes, 80 million people vote for the guy who says that climate change is a chinese hoax and we should be burning """clean""" coal but the actual problem is the people who don't like pretending things are fine.

Well according to the c-roads simulator, if we reduce emmissions to zero this year, it still results in +1.5 C increase by the end of the century and stays there. I think that's roughly accurate if I recall the last IPCC report. At this point it's more a question of what we can do to prepare ourselves for the fallout, we've done our waving to the moments when we could do something as they passed by. The real question…
this is non-sense according to the ipcc models
for 1.5C, we still have a budget of 200BN tonCO2e
for 2C, we have about 1TN tonCO2e
for 2.5C, 2TN ton, is within current trajectory of progress
we currently emmit about 50BN tons/annum
All of the above are bad, but degrees (ha! pun!) matter
> China's overfishing
Bashing the developing world is not helpful. The US account for a massive chunk of historical emissions and excess consumption.

What do you propose to do that is a complete solution and timely?
Our current problems:
- Climate Change (CC)
- Biodiversity Loss (BL)
- Deforestation (D)
- Water Scarcity (WS)
- Ocean Acidification (OA)
- Resource Depletion (RD)
- Pollution (P)
- Land Degradation (LD)
- Food Insecurity (FI)
- Social Inequity (SI)
We have to solve all those to have a chance to repair things. Repair too little and we'll end up as Rome did (they also tried to solve their problems when they realized they're facing the end, but did too little and paid the price). All those problems have their main culprits and plethora of solutions. It's not that we don't know what and how, but we don't have the will.
a] acknowledge that our problem is ecological overshoot, and climate change is just one of its symptoms
b] stop polluting atmosphere ... stop fossil fuels asap, stop adding unnecessary co2 + methane + n20 (CC, P)
c] stop polluting soils & water ... reform agriculture, stop animal agriculture, plant-based diets (BL, WS, OA, P)
d] stop economic drivers of exponential growth of humans ... reform political, economic & financial system, handle inequality, ubi, housing, etc. (SI, FI)
e] stop overconsumption ... degrowth, ubi, walkable cities & reform zone planning, public transport, wfh, remove subsidies for polluting & unsustainable sectors (CC, BL, D, OA, RD, P, LD, FI, SI)
f] stop overexploiting nature ... circular economy, degrowth (BL, D, RD, P)
g] store carbon - reforest, rewild (abolishment of animal ag frees up an area as big as Africa) (CC, BL, D, WS, OA, RD, P, LD, FI, SI)
h] store carbon - enable return of wildlife ... big, continuous primeval rain forests and grasslands (CC, BL, D, WS, LD)
i] store carbon - stop industrial fishing, let marine life rebound to previous levels (70-90% gone already, incl. plankton) (CC, BL, OA, SI)
I'm probably forgetting a lot. But that'd be enough to stop it and begin the path towards sustainability.
