Climate change

Where does the Earth get energy to keep warm?

• from the world ocean

• from the Sun

• from the Moon

When there is too much heat on the Earth...

• some of it should be released back into space

• all of it must be absorbed by the Earth

• it stays in the upper layers of the atmosphere

What might happen if there is too much carbon dioxide in

the atmosphere?

• the gases won’t let the heat reach the Earth and the temperature will go down

• the gases will trap the heat creating the greenhouse effect

  and increasing world temperatures

• the gasses will lower the sea level and reduce marine

  biodiversity

The biggest amount of carbon dioxide is released into the

atmosphere…

• when it rains

• when fuel is burnt

• when plants grow

The main way carbon dioxide is absorbed…

• by some animals species to breathe

• by plants and phytoplankton for photosynthesis

• by factories to produce cars

If the world temperature rises too much, one of the most

dramatic results of global warming will be that:

• some areas will actually get forever cold making them

  uncomfortable to live in

• warmer weather all over the world will boost tourism

• glaciers will melt, the sea level will rise and a lot of coastal

  regions will drown

Some scientists say we wouldn’t have damaged the

environment so much if…

• we had invested more money in agriculture

• we hadn’t started the Industrial Revolution in the 18th

  century

• we had made the emissions of greenhouse gasses go into

  the outer space

If the climate changed enough, …

• a lot of areas would become unbearably hot, which would

  lead to animal and people extinction

• the Earth would lose all of its liquid water supplies

• we could try to do the same with other planets to make

  them suitable for living
