Alaska's rivers are turning orange and no one knows why
Alaska's rivers are turning orange and no one knows why
In recent years, scientists have observed streams and rivers that have turned a vibrant orange color across Alaska's Arctic region.
You're viewing a single thread.
Pretty misleading title.
It is known why the rivers are running orange. It is because the permafrost is thawing.
Sure, the exact, specific process causing the oxidation is being debated by scientists, but ... the reason is because the permafrost is thawing.
Anyway, what this nearly certainly means is that the artic has already blown past the feared warming tipping point and is now releasing methane, which is a much more potent greenhouse gas than CO2.
This article should be focusing on how this likely indicates that climate change will intensify faster than commonly understood by the general public.
But instead it diverts from this.
Hehehehe

Which makes the title accurate? I didn't find it misleading at all.
It's more like the article is focusing on the wrong part of this story. The exact mechanism can be debated but we know what's happening and why: global warming. The article just doesn't want to acknowledge that so it focuses on the fact that science hasn't conclusively figured out the mechanism.
It's not focusing on what you want it to focus on. But that doesn't make it the wrong thing.
It would be like saying "the glass feel of the table, but we don't know why it hit the ground" just because we do not understand gravity in every way possible.
I don't like your analogy. We understand the physics of falling pretty well. We do not understand the chemistry of this reaction.
Maybe "the glass fell because of humans". Did they push it off a table? Drop it? Place it inn the counter wrong?
Edit: let me put it this way - the water could turn orange without a melting permafrost right? So while the change in this instance may be triggered by melting permafrost it is not a necessary condition. The cause is something more necessary.
What makes your think that we do not understand the chemistry here?
Where do we start the "x is caused by y"? The way it actually happened? Then melting permafrost is indeed the first step. If you want to go by how we ended up perceiving it, then you need to start, for example, at how the brown color came to be. Then where that came from. Then what caused it to be made. Etc.
There's definitely a long chain of events that led to these rivers turning orange.
It would be unsatisfying to say "the universe coming into existence caused it". You need to pick a level to stop at. You're satisfied with "melting permafrost causes water to turn orange" but I think it's very reasonable to step a level down. The title is accurate in that regard. The people complaining seem to want the article to be more political.
BTW this discussion reminds me of when Feynman was asked about magnetism.
