Global Warming means that the atmosphere warms up . This changes the climate of the earth . When the atmosphere warms up , the weather becomes more violent . This makes storms very strong . Periods of droughts become long in some places . In other places , it rains so much that there are floods . The ice in the North South poles melts and sea levels rise . The future of our planet is in danger . What can we do to save our planet ? In this project , we will collaborate with our students to slow down global warming .
