Climate change triggering growth in old trees - interesting science news

Larch trees, the northernmost tree species on Earth have grown more between 2005 and 2014 as compared to the previous 40 years and scientists put this on climate change.

Further, it has been seen that the oldest trees have shown the biggest growth spurt i.e. trees older than 400 years have shown the most rapid growth.

It has been seen that the soil warming due to global warming is behind this teenage like growth spurt in old trees. While this is good in the short term, it could spell a disaster in the long term, because slow-growing trees will ultimately degrade due to raising soil temperatures.
