It's not simple, is it?

Modelling the complexities of nature is not a simple task, nor a certain one. We keep finding new, surprising things to factor in to our calculations... The big blue ocean is getting noisier. Sound can now travel further than it did a century ago, thanks to carbon emissions that have made the oceans more acidic.

OTOH, this is not a reason to throw our hands in the air and say, "too hard". Rather it should egg us on to further discovery and understanding. And quickly, before our planet says "enough".
