New report on Global Carbon Strategy

05.10.2010, Age: 3999 days

Today, the Group on Earth Observations (GEO), in which more than 130 governments and leading international organizations are collaborating, published its latest report.

From the Executive Summary:

Understanding the global carbon cycle, and predicting its evolution under future climate scenarios is one of the biggest challenges facing science today; there are huge societal implications. The uncertainty in the natural sinks of the carbon cycle is a major contributor to the uncertainty in climate predictions. The feedbacks between climate change and the carbon reservoirs are not well known or understood. The spatial and temporal distribution of natural sinks over land and oceans remains elusive, which precludes better quantification of their underlying mechanisms and drivers. In addition to natural sinks, anthropogenic emissions from fossil fuel burning and land use change need to be known at regional level and with better accuracy. These uncertainties must be reduced to underpin well-informed, evidence-based policy action.

Current uncertainties on the space-time distribution of CO2 and CH4 fluxes are very large. For well informed policy action aiming to curve down the future increase of CO2 and CH4, these uncertainties must be reduced, by establishing an Integrated Global Carbon Observing system (IGCO). The main goal of this report is to describe the building blocks and coordinated implementation of such an Integrated Global Carbon Observing system.
