In 2015, leaders from many countries met in Paris. They made a big promise to work together. This was the Paris Agreement. The goal was to protect the Earth from getting too warm.
Now, it is ten years later. Many things are different. We use more clean energy from the sun and wind. This is good for our planet. Clean energy is becoming cheaper and more common.
But the Earth is still getting warmer. We still have a big challenge. The work is not finished. Everyone needs to do more to keep our planet safe for the future.
