A marker is painted on a trunk in Tangkoko forest, a protected habitat for many species including Sulawesi black-crested macaques (Macaca nigra) located in North Sulawesi, Indonesia. The earth's forests, currently around 4 billion hectares in total, remain a net-sink for carbon dioxide, which collectively emit 8.1 billion metric tons of carbon each year and absorb 16 billion metric tons, according to Jennifer Forgesen in her article published on Time._Southeast Asia's tropical rainforests are one of the world's three largest systems that are the lungs of the earth, along with the Amazon and Congo River Basin. However, she wrote, Southeast Asia's rainforest are now a net source or carbon emissions due to fires, clearing for plantations, and peat soil drainage._Another report by a team of scientists led by Marine Joly, in relation with the Sulawesi black-crested macaque (Macaca nigra), has revealed that the temperature is increasing in Tangkoko forest. "Between 2012 and 2020, temperatures increased by up to 0.2 degree Celsius per year in the forest, and the overall fruit abundance decreased by 1 percent per year, ” they wrote on International Journal of Primatology._The tropical forests can resist small increases in temperature, but only up to a point, according to a 2020 article on World Economic Forum website. A longer explanation is given by a Science publication in the same year (written by 226 authors): "The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses."
