Some climate scientists and activists are limiting their flying, their consumption of meat and their overall carbon footprints to avoid adding to the global warming they study.

The world continues to increase the amount of heat-trapping carbon dioxide it pumps into the air, but it’s not rising as fast as in the previous couple years.

Children are growing up in a warmer world that will hit them with more and different health problems than their parents experienced, an international report by doctors said.

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.
