Short summary
Recent papers suggest a slow-down in the natural uptake of anthropogenic CO2. We analyse recent trends in atmospheric concentration and known inputs to test for such a slow-down. We see, rather, an increase in uptake compared to a simple response to changing CO2 concentration. Using atmospheric models and statistical techniques we isolate this increased uptake to the northern temperate and boreal continents during summer, suggesting a stronger growing season.
