Greenhouse gases in the Earth system:
Setting the agenda to 2030

2010 marked the 50th anniversary of Dave Keeling’s first publication of atmospheric CO2 measurements. This conference discussed the use of long-term monitoring to understand greenhouse gases in the Earth System. New scientific advances promise regional audit of emissions, assessment of uptakes, and better understanding of controlling and feedback processes. The meeting assessed these, to shape the agenda for the next 20 years.
