The existence of Beringia had a great impact on the spread of the human species only 16,000 years ago – and not long after, climatic periods like the Medieval megadroughts extending into the second millennium moved Vikings to Greenland, vineyards to England and played a role in the collapse of the Inca and Anasazi cultures.
And all this before humans took a role in shaping climate.
Now, according to earth scientists, paleontologists, and scholars in other fields, the planet has entered a new geological phase – the Anthropocene, the age of humans. How did this transition of our species from an apelike ancestor in Africa to the current planetary force occur? What are the prospects for the future of world climate, ecosystems, and our species?
In May, CARTA (The Center for Academic Research and Training in Anthropogeny) gathered the world’s foremost earth scientists, ecologists, and paleoanthropologists to address these questions – and with mostly dreadfully sobering evidence, they place the future of the planet squarely, and irretrievably, in our hands.
