Details of data and studies conducted on Global warming and Deforestation
Answers
Answer:
The trees of tropical forests, like all green plants, take up carbon dioxide from the atmosphere and release oxygen during photosynthesis. They also carry out the opposite process—known as respiration—but when forests are growing, photosynthesis exceeds respiration, and the surplus carbon is stored in tree trunks and roots and in the soil. This is called “sequestration.”
When forests are cut down, much of that stored carbon is released into the atmosphere again as CO2. This is how deforestation and forest degradation contribute to global warming.
The consensus among climate scientists is that CO2 from tropical deforestation now makes up less than 10 percent of global warming pollution. This percentage has gone down in recent decades, partly due to some success in reducing deforestation, but also because greenhouse gases from burning fossil fuels—by far the principal cause of climate change—have continued to increase.
