The Effects of Climate Change: Crash Course Biology #9

Показать описание

Climate change shakes up all of Earth’s systems, including the living ones. In this episode of Crash Course Biology, we’ll see how climate change’s effects rattle the entire chain of life. Changes felt in one population ripple out to affect entire communities and ecosystems—whether they’re composed of pine trees, puffins, or people.

Chapters:
A Changing Climate 00:00
Ecosystem Effects 2:21
Ecosystem Responses 4:38
Increased Carbon Dioxide 7:04
Effects on Society 8:46

The people who are destroying the planet for profit have names and addresses. Do not let videos like this get you depressed and down because they blame you. Instead get angry that the wrong people are being blamed.

Crash Course has gotten an excellent pair of hosts for their currently running series. I really enjoy coming back each week to learn more about biology and botany!

A good, simplified explanation - but still not simple enough for the type of person who thinks that climate change either won't affect humans at all, or is something that we just need to adapt to.

Great video and resource for us teachers to engage in constructive conversations with our students about the impact of global warming

Climate Change is currently my number 1 source of anxiety at the moment. I'm in desperate need of some good news about the whole topic...

Half an hour in and so far, so good but just waiting for all the climate scientists who got their degrees from TikTok to show up acting like they know more than actual climate scientists
