While the world’s forests can play an important role in absorbing carbon dioxide and slowing climate change, new research indicates that elevated CO2 concentrations do not necessarily boost forests and that higher temperatures could cause changes in trees that reduce their ability grow.

The South Pole has warmed at a rate three times the global average over the last three decades, according to a new study in the journal Nature Climate Change. Temperatures at the Amundsen-Scott research station in Antarctica rose by 1.8 degrees Celsius between 1989 and 2018. For comparison, global temperatures rose a total 0.5 to 0.6 degrees C during the same 30-year period.

Climate change models have underestimated the amount of carbon dioxide that will be emitted from thawing permafrost by as much as 14 percent, according to a new study published in the journal Geophysical Research Letters. The research incorporates a key pathway for CO2 to enter the atmosphere that is missing from other models: when carbon from thawing permafrost is flushed into waterways and converted to CO2 by sunlight.
