Comments P.169 left column top paragraph: "The forests of Amazonia (ref 1) covered about 5.4 million km^2 in 2001, approximately 87% of their original extent (primary source), with 62% in Brazil. They host perhaps a quarter of the world's terrestrial species (ref 3) and account for about 15% of global terrestrial photosynthesis (ref 4). Evaporation and condensation over Amazonia are engines of the global atmospheric circulation, having downstream effects on precipitation across South America and further afield across the Northern Hemisphere (refs 5, 6). Amazonian forests have been an important and continuous part of Earth system functioning since the Cretaceous (ref 7)."
