World leaders haven't been able to come up with a big agreement at the Copenhagen climate change summit.

Instead America agreed to work towards limiting temperature rises to just two degrees along with China, India, Brazil and South Africa.

For two weeks officials from 192 nations have been meeting in Denmark to try to come up with a deal.

Green campaigners say they're unhappy leaders didn't work harder to set tough legal limits on pollution levels.

Many people had hoped that countries would agree to reducing the amount of greenhouse gases that countries can produce.
