The world smells different now. That's a big problem.

The world has changed. I can smell it in the air. Learn more about the chemical processes underlying ocean acidification and smell with Brilliant: https://www.brilliant.org/simonclark

This video is about how mundane experiences will be different in a warmer world. You may already be aware that things like wildfires and droughts will become more common, but everyday experiences will also change. Food will taste different, tropical diseases will become more common, and the world will smell different. To us on the land and to creatures in the sea. This in itself is a problem, but its nothing compared to the biological implications of these changes.

This one's really depressing, sorry.

The world smells different thanks to climate change, with a rise in global temperatures and ocean acidification changing how the world smells. That means the scent molecules in the air and water have changed but also how we smell has changed. This science video essay talks about chemistry of smells as well as the biology of climate change and how a warmer world will smell different.
