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…

So, 4 years till we definitively get there? That honestly sounds worse because this was a hypothetical, we absolutely cannot stop our emissions to any meaningful degree if we want to continue living in a society.

And even if we magically did stop all direct emissions, there are secondary warming processes that have started and cannot be stopped. The oceans absorb a quarter of all CO2 which they will start to outgass once the atmosphere concentration stops increasing. The melted glacial masses have reduced the planet's reflectivity, increasing the greenhouse effect. Permafrost thawing is causing methane releases, etc.

> Bashing the developing world is not helpful. The US account for a massive chunk of historical emissions and excess consumption.

Oh my bad, do keep doing it until all the fish are completely gone and we all starve to death because dumb people did things centuries ago. Yes the developed world has an obligation to assist in all ways possible to make sure progress and development can continue in a clean and sustainable way, but past crimes don't condone present ones.

I mentioned China here specifically since they're an outlier in the topic, with vast ocean going fishing fleets emptying stock in even less developed countries that need it, i.e. Indonesia, Africa.

"If this ocean current is collapsing because of the current temperature anomaly, then it has happened." It must be my reading comprehension that's off, but what has happened? What is "it", the ocean current collapsing? The thing is, I don't see anywhere in the article that says it is collapsing. "A new study published Tuesday in the journal Nature, found that the Atlantic Meridional Overturning Current – of which the…

I think what OP wants to say is that despite the timeline for the event being in the future, nothing we can do today will prevent it from happening. The triggers for the event are in the past and nothing can be done, therefore "it has happened".

That only makes sense if the predictions are accurate and highly probable. Time unfortunately, has shown that these dire predictions are often wrong.

There has been a good 20 years of climate hysteria to pull from. All one has to do is look at old newspapers and read the dire predictions from 2010 to have a good laugh at our sensational media.

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.

Ok but please don’t let your disappointment in CNN become yet another excuse for you or other people to keep ignoring the brutal realities of climate change.

How can anyone on HN ignore it when there are a dozen climate emergency articles on the front page every day? Fatigue is setting in.

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

Climate moves a lot slower.

We should plan for it, not ban another “plastic straw”

maybe if we pay more taxes and stop eating hamburgers we can solve it

Let's imagine we stopped all C02 production tomorrow. How long it will take for climate to start going back to "sane" measurements?

It would take shorter than if we were to stop CO2 production at any later date. The best time to plant a tree was 20 years ago, and the second-best time is right now. Do what you can. Live sustainably. Vote righteously. Have consideration for the future.

Probably best not starve the trees. Co2 is only 300-400ppm on the atmosphere

We the people dont need to pay more taxes but the polluting companies should. We the people should not keep doing the polluting companies favours by focusing on complaining about things like veggie burgers and paper straws. We should keep demanding real action.

If you think paper straws and tree planting is dumb and useless (which I can totally relate to), don’t use that to mock the whole enterprise but pressure all the politicians to resist the moneyed interests and take meaningful action.

I was merely presenting my interpretation of what OP wanted to say.

However I wouldn't classify Nature as "sensational media", the authors of the original are a physicist and a mathematician from a well known University.

And I wouldn't call it hysteria when barely anything gets done for the actual climate at a nation state level.
