Global warming is when the Earth's temperature is slowly getting hotter!
What Does That Mean?
Imagine Earth is like a giant greenhouse. The sun's rays come in and warm things up. Normally, some of that heat escapes back into space. But global warming is happening because certain gases in the air, like carbon dioxide, are trapping more heat than usual. Think of it like adding extra blankets to your bed - you get too warm!
Why is it Happening?
Most of these extra gases come from things people do. Burning fuels like coal, oil, and gas in power plants, cars, and factories releases a lot of carbon dioxide. Cutting down forests also contributes because trees help absorb carbon dioxide from the air. Since the Industrial Revolution, human activities have caused the Earth to warm by about 1°C (almost 2°F).
Why is it a Problem?
Even a little warming can cause big problems:
- Melting Ice: Glaciers and ice caps are melting, causing sea levels to rise. This can flood coastal areas.
- Extreme Weather: We're seeing more heat waves, stronger storms, and more droughts.
- Harm to Animals: Many animals and plants may not be able to adapt to the changing climate, which can threaten their survival.
- Changes in Rainfall: Some places might get too much rain and others might not get enough.
What Can We Do About It?
Luckily, there are things we can do to help stop global warming:
- Use Less Energy: Turn off lights when you leave a room, and don't waste electricity.
- Recycle: Recycling helps save energy and resources.
- Walk or Bike: Instead of driving, try walking or biking whenever possible.
- Plant Trees: Trees absorb carbon dioxide from the air, helping to clean the atmosphere.
- Talk About It: Encourage your family and friends to take action, too!
Even small changes can make a big difference!
