Understand the science behind the greenhouse effect and trace the history of climate science from its earliest theorized linkage to human activity.
View key data that provide evidence of climatic trends, including atmospheric composition, ice cover, sea levels, and surface temperatures.
Explore some key drivers of climate change and the ways in which a changing climate influences the natural systems on which humans rely.
How can we minimize further disruption of the Earth's natural systems? And how can we learn to adapt to changes that are already taking place?
