According to a new study using remote sensing technology, mountain trees 'rose' between 2000 and 2010, when the effects of the climate crisis accelerated. The study found that 70 per cent of the tree cover in the regions studied moved uphill. Scientists from the Southern University of Science and Technology in Shenzhen, China, mapped the highest points of tree cover in the mountains. They found that, on average, these wooded areas move upwards by 1.2 metres per year, with the shift being greatest in the tropics, with an average increase of 3.1 metres per year, and the rate of change accelerating in all regions. For the study, about 1 million kilometres of tree lines were monitored in 243 mountainous regions worldwide. According to the study, the tree lines are still moving, indicating that they are sensitive to climate change beyond human influence.
