Document Summary
The process of attribution requires the detection of a change in the observed variable or closely associated variables. Attribution seeks to determine whether a specified set of external forcings and/or drivers are the cause of an observed change in a specific system. Energy supply is the largest culprit of greenhouse gas emission (26%) Proposed by paul crutzen, describing the time since 18th century onward as a new geological era, marked by human activity. Fatalistic denial: there"s nothing i can do about it. Unit 10: glaciers and landforms from moving ice. A glacier is a large mass of perennial ice, resting on land or floating shelf-like in the sea adjacent to land. Glaciers form by the accumulation and recrystallization of snow. They move under the pressure of their own mass and the pull of gravity. Differentiate between alpine and continental glaciers and describe their principal features. Describe the process of glacial ice formation and portray the mechanics of glacial movement.
