CLIMATE CHANGE

Part 3 of 9 in PLANETARY BOUNDARIES

Climate change is a loaded topic and you can dig deep into intimidating mathematical calculations and chemistry. What it all boils down to (pun intended) are the molecules in our atmosphere. Before the industrial revolution, it worked like this: The sun shines down on earth and mostly the energy bounces back out to space. Water vapour and some carbonĀ  dioxide keeps a fraction of the energy maintaining warmth. This way, the sun warms the earth enough to sustain life but doesn’t burn us to a crisp.
With carbon dioxide, methane, nitrous oxide, hydroflourocarbons and other gases in the atmosphere, a harmful amount of the sun’s heat is trapped in our atmosphere and not enough is reflected back out into space.
This is ultimately the greenhouse effect which warms our planet. This is why we are reaching record high temperatures and earth’s creatures are behaving differently.

I got so lost in links of links of links in Wikipeadia and whilst I understood the just of it, I couldn’t write about it the way I would like to. Luckily, there are some brainiacs on Youtube that can explain it perfectly in visuals.

Enjoy the videos below and pat yourself on the back for learning the science behind climate change. They all compliment each other and are fun to watch.
