Global warming is when the world heats up by greenhouse gasses (like methane and carbon dioxide) These gasses are released into the atmosphere. The gasses trap heat and light from the sun making the earth warm up. Man made (or woman made) machines such as cars, factories and ships that use fossil fuels make these gasses.
Animals and and humans are affected everywhere by this. The warming of the Earth causes icebergs to melt. This causes the water level to rise which causes flooding. Polar bears (as seen on the top right) and penguins are being forced to leave the poles because of ice melting.
We can help to stop this by using only as much water as we need and conserving energy by turning off lights when we don’t need them. These are only a few examples. There are a lot more. To learn more, go to nrdc.org/globalwarming.
