Global Climate Change Module
How is the Earth's climate changing? Within the mainstream scientific community the fundamentals of global warming and climate change are no longer in question and increasing evidence shows that human activities make a significant contribution to this change. Examine evidence of climate change from different parts of the Earth’s system and consider what it means to live on a planet with a dynamically changing climate.
In the Earth system, a change in one part of the system will lead to a change in another part through positive and negative feedbacks. Feedbacks render some parts of the Earth more sensitive to climate change than others. Examine the evidence for changes in ice cover at the Arctic and explore why climate changes at the poles are so important to the rest of the climate system.
The present and future impacts of global climate change on human populations are unevenly distributed across the planet. As a consequence of a warming climate, sea levels are rising at a rate of more than 3 millimeters (mm) a year. Learn how sea level rise will have increasingly serious consequences for human health and life quality.
