Climate change will alter ocean bacteria crucial to food cha

[compassrose]

Meh. This is extremely close to my field. Things tend to level off or revert during chronic high CO2 exposure. And this whole hypothesis falls apart when you compare the Fe and P affinities and strategies with other organisms. There's already no measurable Fe in most of the surface ocean-- it's already scavenged too quickly for us to even measure. So there might be more pressure, but the competition is already just about as stiff as it can be.

I think the bigger concern is still rising CO2 leading to ocean acidification and killing off calcium carbonate-dependent organisms.

Sorry for the jargon. But of the many things to worry about, I'd keep this far down the list.

If we can't get people to care about cuddly polar bear cubs, how will we convince them bacteria are important?

(My hope for comprehensive understanding of the food chain is low.)

I know, I read it.

I'm feeling kind of crotchety against these guys since there is so much we don't know that's happening NOW that it's hard to predict what's going to happen to the ocean in 85 years time. Let alone simulate what might happen in 85 years time to run an accurate experiment. As compassrose said, ocean acidification might kill off everything before it even gets to that point.

Well. Good thing the rapture is coming at the end of September.

When you guys do you booze run, make sure to stock up on sushi too.

Don't apologize. It's hot. Say something else sciencey.

Siderophores. Half-saturation constant. Diazotroph. (All directly related to the article, too!)
