Higher temperatures – smaller trees?
As the climate changes, ecosystems around the world are also changing. Some say trees are getting shorter and younger, but there are ways to mitigate this. Environmental and climate changes are transforming the world’s forests. A new study published by scientists at the Pacific Northwest National Laboratory (PNNL) suggests that these changes are causing trees to become smaller and younger. Is this really the case and if yes, what can we do about it? Indeed, the rising temperatures are a source of stress for trees. Matti Maajärvi, Senior Specialist of Global Forest Affairs at UPM Forest, says that as the climate changes, “the frequency of negative natural phenomena – such as extreme droughts, forest fires and mass outbursts of pests – can impact the forests adversely.”
