The latest report on global carbon emissions released this week revealed that carbon dioxide emissions will likely reach 40 billion tonnes this year. Growth in emissions continues to match the worst-case…
Deforested tropical rainforests have been found to replenish their carbon faster than their rich biodiversity. Research conducted…
Using tree measurements by Papua New Guinean villagers such as Daniel and Jackson, scientists can estimate that this tree stores about one tonne of carbon in its trunk and branches.
