Forests Under Stress: The Unsettling Arithmetic of CO2 and Ozone The latest findings from the Aspen FACE experiment in Wisconsin have delivered a sobering lesson on the intricate dance between atmospheric gases and forest productivity.
For over a decade, scientists altered the air surrounding young forest communities to gauge their response to elevated levels of carbon dioxide (CO2) and ozone (O3).
The results are a stark reminder that forests are not the straightforward carbon sinks we often assume them to be.
