At the heart of a forest in central Massachusetts, one can find a typical red oak tree. Its only distinguishing feature, aside from its staleness, is that it tweets information about climate change.
The 87-foot Northern Red Oak has relived the global warming crisis.
The centuries-old oak tree’s first social media debut is the brainchild of Harvard Forest Postdoctoral Fellow Tim Rademacher and is now a joint effort with Clarisse Hart, who oversees outreach and education for the forest.
“We did the work as a team to give the tree a voice, which we decided made the most sense in the first person and even with the personality,” says Rademacher. it becomes relevant to a larger audience.” .
“But most importantly, our Witness Tree is an objective data-driven account, which I expect will amplify messages about climate change. But we don’t decide what gets posted, what gets posted. the tree will do.”
Trees have lived to demonstrate the changes of weather. This Northern red oak tree has been fitted with sensors by a team from Harvard Forest, information from which is sent into software to allow the tree to communicate.
Last month was quite dry, with a temperature of 32.7 ℃ (90.9 ℉) and only 99.3 mm of rainfall in Harvard Forest.

In addition to the growth sensor that continuously monitors the tree, the Twitter tree also has a sap flow sensor that measures the amount of liquid going up and down the tree.
A camera that continuously takes pictures of the foliage is also present. All of this information is combined to create a code, which is then posted on the Witness Tree Twitter page.

The tree is about 100 years old and has seen a lot of extreme weather. This tree was there and unharmed when a great New England storm hit in 1938.
Such advanced techniques can not only demonstrate how rapidly the climate is changing, but also show how urgent it is to take immediate action to protect trees that have been around for more than a century. any.
