Born in Florence, Italy, Marco claims to be a descendant of Giovanni Villani, a chronicler of medieval times. He has been writing on newspapers since the age of 20, mostly about science and technology, with a focus on energy and (un)sustainability. He has been covering the United Nations conferences on climate change since COP11 in Montreal, in 2006. His semi-serious book ’The Brain: A User’s Manual’ (published by Short Books) has been translated into ten languages and it is probably the most intelligent thing he has ever produced in life. Apart from authoring Geographical’s monthly ClimateWatch column, of course.
