A New Chapter in Earth History?

Observing that the mid-twentieth century coincides with the 'Great Acceleration' of human population growth, economic development and industrialization, an international group of scientists has proposed that it should mark the dawn of a new geological age in Earth history – the Anthropocene. The emergence of megacities, facilitated by the production of huge quantities of concrete, is coincident with earth movement on a vast scale, the researchers say. Mineral exploitation has resulted in the generation of marked geochemical signatures across the globe and this age of hydrocarbon burning has resulted in greatly increased carbon emissions. Humanity's modification of the planet has caused an increase in species extinctions and invasions. All these features are being expressed in the sediments accumulating across the planet and will be recognizable to the geoscientists of the far future
