Past Global Changes

From: Steffen et al. 2004. Responses of the biophysical Earth System to the accelerating 'human enterprise'.The biophysical responsesof the Earth System showmany of the same featuresas the Great Accelerationin the human enterprise.. 44% of the world's population live within 150 km of a coastline.

    4. Land-Ocean: LOICZ Anthropogenic influences on the river catchment & coastal zone interaction Fate & transformation of materials in coastal & shelf waters Towards coastal system sustainability by managing land-ocean interactions Approximately 37% (2.07 billion) of the world’s population (5.62 billion) live within 100km of a coastline and approximately 44% live within 150km of a coastline* Approximately 37% (2.07 billion) of the world’s population (5.62 billion) live within 100km of a coastline and approximately 44% live within 150km of a coastline*

    8. Changes in N deposition Humans have already doubled the flow of reactive nitrogen on the continents, and some projections suggest that this may increase by roughly a further two thirds by 2050 Note that the 2050 projection is from the original source, not from the MA Scenarios.Note that the 2050 projection is from the original source, not from the MA Scenarios.

    15. The Stages of the Anthropocene Main point: While much of the attention has been directed to surface temperature increases and global climate change, Global (Environmental) Change is much broader in scope.
