SUMMARY:On trends and feedbacks in the Contemporary Global Carbon Cycle -

DESCRIPTION:Anthropogenic greenhouse forcing may be enhanced by Climate 
 – Carbon Cycle feedbacks. Examples of such feedbacks are large-scale bio
 me alterations like rainforest to savannah conversion\, or changes in the 
 ocean anthropogenic carbon uptake pathways. Recently there have been sever
 al studies indicating that such feedbacks are already operating. This talk
  addresses the question what existin g data tell us about such feedbacks. 
 The talk will first use the global atmospheric greenhouse gas record and s
 imple models to analyze whether atmospheric carbon dioxide records support
  the conclusions on feedbacks of published studies. Next\, data from a lar
 ge-scale long-term Amazon forest functioning network will be discussed in 
 the same light. Then implications of the first year of atmospheric CO2 3D 
 data from a now regular greenhouse gas observation program over the Amazon
  basin based on aircraft will be presented and put in perspective with res
 ults from other recent studies. Finally I’ll summarize.
