Death of a Spruce Tree

The climate change has a huge effect on the health of forests. The study showed that the forest fire is not happening which caused the dead trees to not be replaced by new ones. Also, due to the climate change, the growing of the tree is harder to estimate because they believed that the trees are storing more CO2. Bond-Lamberty had stated that "We need to understand forests in the long term, but forests change slowly and researchers don't live that long." This is correct because for some trees, it takes 100 of years for it to become a full size adult tree. In the NASA-led BOREAS project in 1990s, they studied the Northern Old Black Spruce site and collected samples from 3 different years between 2001-12. They had suggested that the slow-growth years was due to low rainfall and high temperature. Then, they found a bigger territories where the oldest trees started growing in the mid-1800s, and Bong-Lamberty stated that between the 5 years, the trees are dying and not being replaced. Also, the fact that the tree takes in CO2, the study shown that the middle-aged trees fatten up. As the period continued the world will get warmer and it will be a rotten time for the forest.
