  • In a new paper published today in the Annals of the Missouri Botanical Garden, Florida Tech biology professor Mark Bush describes how the vast Amazonian rainforest could be replaced by savanna.
  • One of the key points of the paper, “New and repeating tipping points: the interplay of fire, climate change and deforestation in Neotropical ecosystems,” is that while no individual government can control climate change, fire can be regulated through policy.
  • Anthropogenic warming would bring those temperatures by the end of this century, but increased burning creates hotter, drier, less shaded landscapes that could hasten that transition.
