As global temperatures rise, trees around the world are experiencing longer growing seasons, sometimes as much as 3 extra weeks per year. All that time helps trees grow faster. But a study of the forests of Central Europe suggests the higher temperatures—combined with pollution from auto exhaust and farms—are making wood weaker, resulting in trees that break more easily and lumber that is less durable.
Forests may suffer more damage from storms and may be less efficient at soaking up the greenhouse gas carbon dioxide (CO2) than scientists had thought but still
For the past 100 years, trees have been experiencing growth spurts in temperate regions from Maryland to Finland, to Central Europe, where the growth rate of beech and spruce has sped up nearly 77% since 1870.
