On a national scale, extreme weather events have become far more prevalent and severe, causing untold damage to livelihoods and economies.

Among the most feared effects of climate change in Brazil is the degradation and transformation of natural habitats. For years, experts have warned about the Amazon approaching a “tipping point,” with a mixture of altered climates and deforestation turning the biome into a savannah, as opposed to a closed canopy rainforest. Recent research shows that this transition may come much sooner than initially expected.
