In a joint report published in 2021, the IPCC and IPBES point out that this correlation between climate change and biodiversity loss implies that, in order to satisfactorily address one of these two issues, it is necessary to address the other.
The Amazon rainforest is a prime example of this interdependence. A popular symbol of the negative impact of human activities on its biodiversity, the Amazon is also a carbon sink that absorbs a portion of anthropogenic CO2 emissions each year. Today it contains an amount of carbon equivalent to a decade of global human emissions (3). Mitigating the effects of climate change will have a positive impact on the richness of biodiversity in the Amazon and mitigating the loss of biodiversity in this region will have a positive impact on climate change.
To halt biodiversity loss and mitigate climate change, the IPBES and IPCC report calls for a major increase in the number of protected areas to 30-50% of land and ocean, up from 15% of land and 7.5% of ocean today.
