Climate change in Brazil is mainly the climate of Brazil getting hotter and drier. The greenhouse effect of excess carbon dioxide and methane emissions makes the Amazon rainforest hotter and drier, resulting in more wildfires in Brazil. Parts of the rainforest risk becoming savanna.
Brazil's greenhouse gas emissions per person are higher than the global average, and Brazil is among the countries which emit a large amount of greenhouse gases. Greenhouse gas emissions by Brazil are almost 3% of the annual world total,[1] firstly due to cutting down trees in the Amazon rainforest, which emitted more carbon dioxide in the 2010s than it absorbed,[2] and secondly from large cattle farms, where cows belch methane. In the Paris Agreement, Brazil promised to reduce its emissions, but the Bolsonaro government between 2019 and 2022 has been criticized for doing too little to limit climate change or adapt to climate change.[3]
