The atmosphere is a blanket of gases around the Earth.For thousands of years these gases have kept the planet’s temperature at about 15oC.But now,because of
pollution,there are more and more hot gases put into the atmosphere.This means the Earth is getting hotter.A greenhouse becomes hot for the same reason.It’s a glass that
lets the sun’s heat pass through,then stop some of it from leaving.That’s why scientists call the problem of the Earth’s rising temperature “the Greenhouse Effect”.
Scientists agree that the Greenhouse Effect will add between 1.5oC-4oC to the Earth’s temperature by 2030.This will change the weather everywhere.
Then there is the problem of food.When the climate changes there will be less food in the world.At the moment areas like the Midwest of America and central Russia grow
a lot of wheat.In the future that may change when the USA and Russia become too dry for farming.Other countries will become wetter,but that won’t help.The soil won’t
possible to grow the same amount of food as before.
We can’t stop the Greenhouse Effect.However,we can slow it down if we use less fossil fuel,protect rain-forest,use more natural energy from the sun,the sea and wind.
