Abstract
An updated analysis of atmospheric CO2 observations and other time series constraints on the Earth’s carbon system reveals some intriguing new puzzles, such as a large jump of almost 1 Pg C/yr in the land carbon uptake occurring abruptly sometime around 1988/1989. Furthermore, while a regional synthesis and assessment of the land carbon sources and sinks over the post 1988/1989 period reveals broad agreement that the Northern Hemisphere land is a major sink of atmospheric CO2, there remain major discrepancies with regard to the sign and magnitude of the net flux from tropical land.
