Action on climate change means doing things to reduce the effects that humans have on the Earth's climate. You know how you feel really hot in the summer and really cold in the winter? That's because the weather changes all the time. But sometimes the weather changes a lot and it can cause problems for our planet.
People are doing things that make the Earth hotter, like driving cars and using electricity. This is called "greenhouse gases" and it's not good for the Earth. It makes the temperature go up, which can cause problems like melting ice and rising sea levels.
We need to take action on climate change to help protect the planet. This means doing things like using less energy, recycling more, planting more trees, and finding ways to use cleaner energy like wind and solar power. By doing all these things, we can help keep the Earth healthy and protect it for the future.
