Here’s the rewritten news article:
The United Nations is making a big effort to help people in the Pacific Islands. These islands are being affected by climate change and rising sea levels.
The UN says that the islands will be one of the most vulnerable places on Earth as the weather gets warmer. This means that more and more people could lose their homes, food, and water.
The UN is working with governments and other organizations to help the Pacific Islands prepare for these changes. They want to make sure that the people who live there have a safe place to go if they need to move away from their homes.
