TRAPPED IN HEAT: how humanity altered Earth's termostast
The “Before and After” (Historical Impact)
The chemistry
Pros and Cons (The Impact Today)
Did you know?
Pros:
The energy generated by burning these fuels powered the industrialization of the modern world, gave us electricity, and built global transportation networks.
It causes severe climate change, melting glaciers, rising sea levels, extreme weather events, ocean acidification, and threatens global biodiversity.
Contras:
Word equation
Chemical equation
Importance: Human activities burn carbon, producing greenhouse gases that trap infrared radiation (heat) in the atmosphere instead of letting it escape into space.
Reactant materials
Products
A fun fact
We knew about this over a century ago! In 1896, Swedish scientist Svante Arrhenius was the first to calculate that doubling atmospheric would warm the planet by several degrees. Funnily enough, coming from a freezing country, he initially thought a warmer climate would be a wonderful thing for Sweden !
Before
After
(Modern Industrial Era):
- Levels skyrocketed past a record-breaking 420 ppm.
- Global average temperature increased by over.
- Extreme weather events (droughts, heatwaves, superstorms) became frequent.
(Pre-Industrial Era)
- Stable global climate for thousands of years.
- levels remained strictly below 280 parts per million (ppm).
- Nature perfectly balanced the gases emitted and absorbed.
