THE GREENHOUSE EFFECT The sun give heats for Earth.Some of the heats escapes into space,but some is trapped by a blanket of gases.This keeps Earth warm enough for us to live here.It is called the greenhouse effect.
Melting Ice Because Earth is getting warmer the ice is melting at the South and North Poles.It is problem because ice changes to water and the sea level is getting higher.Low countries are in dangerous. For example red line is ice at the North Pole 34 years ago.Now,North Pole shed 20percent on ice.
GLOBAL WARMING When we use fossil fuels we make a gas called carbon dioxide.We are putting too much carbon dioxide into the air.It increases the greenhouse effect.This is called global warming.
Extreme Weather Earth has more extreme weather,because global warming is changing climate.This is a big problem for everything plants,animal and people.
WHAT CAN WE DO? Our planet has natural ways to reduce carbon dioxide.Oceans and plants use carbon dioxide,but we make lots of this gas and we are cutting tree.We must using fever fossil flues.We can make energy from the sun,wind or water.
