How do you explain global warming to a 10 year old?
Global warming: The increase in Earth’s average temperature over a long period of time. Carbon dioxide: A gas released by the burning of coal, natural gas, oil, and wood that traps heat in the atmosphere.
What are the 3 main causes of climate change?
The main causes of climate change are:
- Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry.
- Deforestation – because living trees absorb and store carbon dioxide.
