Leaders meet in a city. It is for a big talk. The talk is about the Earth.
Before, leaders made big promises. They said stop using old fuel. Now, they think again. They worry about energy for people.
Some leaders want to go slower. The world is changing. Plans for less bad air are not so fast.
More energy is needed now. Countries use old fuel too. This helps people and business.
The main idea is to keep Earth not too hot. This is a new, good goal. A goal for the year 2050 is hard.
The talk will be about real things. It is not about fast plans. Things are slow and real now.
