2. What is it
Global warming is when the earth heats up (the
temperature rises). It happens when greenhouse gases
(carbon dioxide, water vapour, nitrous oxide, and
methane) trap heat and light from the sun in the
earth’s atmosphere, which increases the temperature.
Global warming is bad for the world
3. Why does it exist?
The greenhouse effect is when
the temperature rises because
the sun’s heat and light is
trapped in the earth’s Global
atmosphere this is just like a warming
bottle in heat.
When it is trapped it makes the
heat inside your bottle stick to
the sides of the bottle. If the
bottle was Earth what would it
be like? It would be very , very
hot
