The changing sound of earth

Claire Asher, the BBC, writes about how the world sounds different than it did a century ago. And the reason is not benign–climate change has had a dramatic effect on the oceans, for example,

How big is the impact, really? Bigger than one might expect. Writes Asher:

In 2015, a US team of scientists and engineers reported that the loudest sound in some waters now comes from millions of tiny bubbles, which are released by melting glaciers and icebergs. In the fjords of Alaska and Antarctica, the average noise level is now over 100 decibels – louder than any ocean environment recorded before.

The world sounds different than it did a century ago

and it’s not for a good reason. Claire Asher, BBC, reports on how climate change and animal extinctions have altered the way our world sounds.  Asher writes that human activity is changing our natural soundscape irreversibly:

In 2015, a US team of scientists and engineers reported that the loudest sound in some waters now comes from millions of tiny bubbles, which are released by melting glaciers and icebergs. In the fjords of Alaska and Antarctica, the average noise level is now over 100 decibels – louder than any ocean environment recorded before.

And it is more than our oceans that are affected.  Asher notes that “natural spaces are now polluted with human-made noises. As we change forests into farms and drive species to extinction, we are fundamentally changing how our world sounds.”
