Mark Williams is a Professor of Palaeobiology at the University of Leicester. He is interested in the evolution of the biosphere over geological timescales, with an emphasis on understanding the rate and degree of current biological change. He was the first secretary of the Anthropocene Working Group from 2009 to 2011. Colin Summerhayes is an Emeritus Associate of the Scott Polar Research Institute at the University of Cambridge. He is a marine geologist and oceanographer with expertise in the role of climate in forming marine sediments, and in interpreting the history of climate from sedimentary records.
