The chemical imbalance driving our changing global climate
In short: This video breaks down the chemistry of our atmosphere, explaining how specific gases trap heat and why human activity is altering the planet's thermal balance.
The Earth's atmosphere is primarily composed of nitrogen, oxygen, argon, and carbon dioxide. While these gases are essential, the concentration of carbon dioxide is rising due to two main human drivers: the burning of fossil fuels and widespread deforestation.
The video explores the greenhouse effect, where gases like carbon dioxide trap solar heat energy, leading to an increase in the planet's average temperature. This global warming triggers significant consequences, including more frequent droughts and floods, rising sea levels, and an increased risk of species extinction and disease outbreaks.
