Attendees listen to Joe Pellegrino, of the Greening the Gateway Cities Program, delivers a presentation on tree care and pruning on Saturday, to neighborhood residents.

Terrestrial ecosystems absorb 25-30 % of fossil fuel carbon emissions. Photosynthesis by plants removes the largest amount of carbon from the atmosphere to make sugars that fuel plant growth. Plants and soil decomposers also release CO2 back to the atmosphere through respiration.

The terrestrial biosphere is currently a net CO2 sink because of a small imbalance between photosynthesis and respiration.

Richer understanding of terrestrial carbon cycles aids more accurate climate change modelling Quantifying the carbon storage potential of terrestrial ecosystems will have to take account of the relative contributions of photosynthesis and respiration to the global carbon cycle. The SOLCA project developed an ambitious approach to tackle this challenge.
