Session Description: 

Overview & Relevance:
The human population contributes to global changein part through enhancing the emission of greenhouse gases. The enhancement is a funtion of the growth in numbers and productivity of the humna population. Numbers and productivity are intricately interwined through the technology and social organization humans create. over the past two or three centuries, the human poopulation has developed unprecedented new technologies that have permitted an exponential growth in both numbers and productivity. This represents a great success of the species in expanding its niche in the world ecosystem. But it also threatens the continued survival of the species and the health of the entire ecosystem. There is today a growing awareness of the threat human sussesses pose, and a mobilization of the world community to address that threat and to attempt to develop strategies for sustained development.

Content:
This workshop was concerned with linkages between population dynamics and biogeochemical cycles. The three main themes covered were
• Greenhouse gases: what we know about anthropogenic emissions. Six major trace gases were addressed: carbon monoxide, carbon diozide, mehtane, nitrous oxide, and two CFCs.
• Impacts of enhanced emissions: what we know about the impact on cliamte, terrestrial and aquatic systems.
• Reactions: adaptation and mitigation

Workshop Topic (s): 
  • Atmospheric Composition
  • Carbon Cycle
  • Human Contributions & Responses
