Ocean acidification

Today, we're running the same experiment.

Ocean pH has dropped zero point one units since pre-industrial times.

That might sound small, but pH is a logarithmic scale.

We're talking about a thirty percent increase in ocean acidity.

So when we hear things like...

Super El Nino brewing in the Pacific, what's that about? Or a weakening AMOC, which stands for Atlantic Meridional Overturning Circulation, that's threatening global infrastructures and food systems, plus ocean acidification.

Why do we need to care about that? Well, we do, and it's a big deal.

So we're going to get into all of it.

I'll go back to Brad DeYoung on the line.

When I started the show, I mentioned we would dig into some concepts, right? So AMOC and Fred Cyr, who's here, just went through that.

But when you and I were talking, you also talked about the importance of ocean acidification.

And I'm just wondering if you could talk a bit on that and why we need to monitor it and what that means.

It's important to note that acidification is so site-specific.

There's areas that are changing more rapidly than others.

Acidification is due to eutrophication, so nutrients that are coming into a system, and also from increased carbon dioxide in the atmosphere.

So to slow that down, there's a lot of talk about reducing our carbon emissions, reducing And that's complicated, right? We've evolved to rely on certain things in this world that have used a lot of gasoline in our travel and whatnot.

So it takes, I think, a shift on an individual level and also as a collective level to be reducing our carbon emissions.
