New Study Suggests Oceans Absorb More CO2 Than Previously Thought (scitechdaily.com) 42
Long-time Slashdot reader schwit1 shared this story from SciTechDaily:
New research confirms that subtle temperature differences at the ocean surface, known as the "ocean skin," increase carbon dioxide absorption. This discovery, based on precise measurements, suggests global oceans absorb 7% more CO2 than previously thought, aiding climate understanding and carbon assessments...
Until now, global estimates of air-sea CO2 fluxes typically ignore the importance of temperature differences in the near-surface layer... Dr Gavin Tilstone, from Plymouth Marine Laboratory (PML), said: "This discovery highlights the intricacy of the ocean's water column structure and how it can influence CO2 draw-down from the atmosphere. Understanding these subtle mechanisms is crucial as we continue to refine our climate models and predictions. It underscores the ocean's vital role in regulating the planet's carbon cycle and climate."

It's interesting, but we can measure the amount of CO2 in the atmosphere and have been doing so for quite some time. The fact the oceans are absorbing 7% more than we'd thought they were doesn't really change the fact that we can measure atmospheric CO2 any time we want to do so.
It's not like this gives us 7% more breathing room than we had before, it's not like if we were actually reducing emissions we wouldn't see the effect on atmospheric CO2 directly.
Extra CO2 is bad for the oceans due to acidification, but if all we paid attention to was air, we'd have a very reliable measurement by which to judge our progress (or lack thereof).

It's the same reason why we keep getting stories about carbon capture. It's pushed by the oil industry in order to slow down the transition to renewables.
Just because the oceans absorb more CO2 doesn't mean that CO2 doesn't have any effects. Having a large increase in CO2 in the oceans can do just as much damage just i

It's not quite as simple as that. But Trump will be able to fix it if we just give him the chance.
Trump is going to fix it the same way he will fix the economy, and also fix immigration. With magic.
Sure the Trump has no actual plan besides soundbites and "experts" say they'll do the opposite of his claims. But that's the beauty of it. It will work because people believe it will work, magic.

One could spin it is a bit of good news as to the prospects of taking action. There's a whole bunch of folks saying "well it's too late, let's just role with it, the damage is done and whatever will be will be". If they find credibly more effective recovery mechanisms that ultimately add up to a levelling off of subjective conditions, or even maybe a slight improvement over decades, then there's good justification for it being a worthwhile pursuit to minimize hydrocarbon usage.

Honestly, I wonder if this is (mildly) bad news.
For one, ocean acidification is bad, and this makes it worse.
But also, the fact 7% more CO2 is being absorbed means we're emitting more CO2 than we realized, and that means our efforts to reduce will need to overcome that added barrier.

Apart from anything else, let's remember that oceans absorbing CO2 isn't some wundercure for climate change. Even if it does slow it, it's at the expense of changing the pH of the ocean, making them more acidic, and having enormous effects on ocean ecosystems.

It's less about how much CO2 is currently in the atmosphere and more about determining factors and accuracy for more precise predictions moving forward.
Hypothetically, it might be a bit of 'good news' *if* you do reduce CO2 that this specific factor might accelerate recovery a little more than previously understood.
It might help shape predictions of degree and timeline of bad stuff, which can be useful because a lot of folks are super dismissive if the scientific consensus is generally right, but misses the

The climate is driven by a number of feedback loops, both positive and negative. You can't develop a predictive climate model with much value without modelling these feedback loops. Unless you capture these sorts of things, your model will pretty much always fail when attempting to model situations we haven't actually experienced.
This is why climate change tends to fall into religious camps. Those who focus too much on positive feedback loops will tell you well get runaway heating and the whole planet will

From the article:
The discovery suggests that rainforests are a more important natural carbon sink than previously estimated using satellite data.
Which means this news on GPP is actually worrying as models suggest that rainfall on some of those rainforests is and will continue to reduce, meaning they will reduce in size. We can already see that GPP isn't sufficient to offset emissions as atmospheric CO2 is increasing, so if we lose one class of carbon sink, we will be in greater trouble. The narrative you probably want to promote is that scientists are dumb and climate change isn't an issue, but that's not what this research is say
