“We have altered the Earth system physically and chemically through disrupting the global cycling of carbon, causing warming of the surface of the Earth and acidification of the oceans; and biologically, through species extinctions and the movement of many species to new locations. Of these myriad changes, summarized in Figure 8.1, some are being preserved in geological archives, including glacier ice and sediments accumulating on the ocean floor.”

“If all other emissions stopped immediately, it would take converting about 50 per cent of all the world’s croplands to forest to reduce carbon dioxide levels to 350 ppm by 2100.”
