QUEST
Quantifying Earth system processes and feedbacks for better informed assessments of alternative futures of the global environment.
Human activities are altering the atmosphere and oceans, transforming ecosystems, and changing the climate, over and above natural changes. Although people are global players in the Earth system, we don’t understand well enough how it works, why it changes, and how it will respond to our growing influence. Yet environmental changes are gathering speed, increasingly affecting ecosystems and human welfare

Scientific debate sparked over carbon sink data
Apparently conflicting results published by researchers QUEST programme reveal the difficulties of accurately estimating sources and "sinks" of CO2, although all of the authors agree that the only way to control climate change is through a drastic reduction in global CO2 emissions - 18.11.09

No slow-down in global CO2 emissions
Evidence published today in Nature Geoscience, by a world-wide team of experts led by Corinne Le Quéré and including Drs Pru Foster, Pierre Friedlingstein, Jo House and Prof Colin Prentice, suggests that the rise in atmospheric CO2 emissions continues to outstrip the ability of the world’s natural ‘sinks’ to absorb carbon. - 18.11.09

Controversial new climate change results
Recently-published research by Dr Wolfgang Knorr, a member of QUEST's core team at University of Bristol, shows that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed the same since 1850, despite a huge rise in emissions over the same period. This suggests that oceans and ecosystems have a greater capacity to absorb CO2 than had been previously expected - 09.11.09
