  1. Integrated Carbon Observing System A European infrastructure to monitor greenhouse gases in the atmosphere Michel Ramonet Laboratoire des Sciences du Climat et de l'Environnement

  2. European Research Infrastructures European priority for the next 20 years Coordination: Philippe Ciais, LSCE Preparatory phase: 2008-2012

  3. Objectives of ICOS • To establish an integrated long-term global GHG observation infrastructure • To determine regional GHG fluxes from observations and attribute these to processes • To enable early detection of surprises • To provide regional GHG budgets for policy support • To provide access and services for data and data products

  4. 2006 Fossil Fuel: 8.4 Gt C CO2 Emissions from Fossil Fuels • Increase rate • 1990 - 1999: 1.3% y-1 • 2000 - 2006: 3.3% y-1 Acceleration of the increase of fossil fuel CO2 emissions since 2000

  5. 10 Actual emissions: CDIAC 450ppm stabilisation Actual emissions: EIA 650ppm stabilisation 9 A1FI 2007 IPCC scenarios A1B 2006 A1T 2005 8 A2 CO2 Emissions (GtC/yr) B1 B2 7 6 5 1990 1995 2000 2005 2010 Recent trend of Fossil Fuel Emissions Recent increase of CO2 emissions higher than all the IPCC's scenarios

  6. CO2 (ppm) Storing all the CO2 in the atmosphere Ice cores Atmosphere Observations CO2 accumulation in the atmosphere Only 46% of the fossil fuel emissions remain in the atmosphere

  7. Atmosphere 46% 4.2 Pg y-1 Land 29% 2.6 Pg y-1 Oceans 26% 2.3 Pg y-1 Canadell et al. 2007, PNAS (updated) Fate of Anthropogenic CO2 Emissions (2000-2007) 1.5 Pg C y-1 + 7.5 Pg C y-1

  8. Climate Change at 55% Discount Natural CO2 sinks absorb 55% of all anthropogenic carbon emissions slowing down climate change significantly. They are in effect a huge subsidy to the global economy worth 50 billions US$ annually if an equivalent sink had to be created using other climate mitigation options (10$ per 1 ton of Carbon)

  9. From Global to Regional Carbon Cycle How can we establish a reliable tracibility of regional sources and sinks ?

  10. Regional Carbon Cycle

  11. ICOS France ~25% of the global network ~15% of the global network Ecosystem Atmosphere ECOSYSTEMS ATMOSPHERE Inspirationnal ICOS networks
