World Court Issues Landmark Opinion on Climate Change Obligations

The highest court at the United Nations, called the ICJ, said that all countries need to work together to stop climate change.

They have to try really hard to lower the amount of pollution going into the air.

The court said countries should make plans to do this, and they should be as ambitious as possible.

If countries don't do this, other countries that are being hurt by climate change could take them to court.

Rich countries that have caused the most pollution are supposed to take the lead.

This is a big deal because it can make countries have to follow stricter rules about pollution, helping to protect the planet from getting too warm.
