The United Nations climate change meeting was held in Madrid, Spain, in December.

Disappointed representatives from about 200 nations attended the meeting.

There were few agreements on how to slow global warming.

U.

N Secretary General Antonio Guterres said he was disappointed with the results.

To be disappointed is to be made unhappy about something because it was not as good as expected.

It is also being sad because something you hoped for did not happen and it can mean unhappiness because someone has behaved badly.
