Jan Zalasiewicz, professore di paleobiologia all'Università di Leicester, approfondisce l'Antropocene.
Jan Zalasiewicz è Professore di Paleobiologia all'Università di Leicester, Regno Unito. All'inizio della sua carriera è stato geologo sul campo e paleontologo presso il British Geological Survey, lavorando per decifrare gli strati dell'Inghilterra orientale e poi le montagne del Galles centrale. Ora insegna geologia e storia della Terra a studenti universitari e post-laurea e studia ecosistemi e ambienti fossili in oltre mezzo miliardo di anni di tempo geologico. Negli ultimi anni è stato coinvolto nello sviluppo di idee sull'Antropocene, il concetto secondo cui gli esseri umani ora guidano gran parte della geologia sulla superficie della Terra, e presiede il Gruppo di lavoro sull'Antropocene della Commissione Internazionale sulla Stratigrafia.
Volcanoes (A very short Introduction) pdf da Jan Zalasiewicz
Volcanoes are some of the most dramatic expressions of the powerful tectonic forces at work in the Earth beneath our feet. But volcanism, a profoundly important feature of Earth, and indeed of other planets and moons too, encompasses much more than just volcanoes themselves. On a planetary
scale, volcanism is an indispensable heat release mechanism, which on Earth allows the conditions for life. IIt releases gases into the atmosphere and produces enormous volumes of rock, and spectacular landscapes - landscapes which, during major eruptions, can be completely reshaped in a matter of
hours. Through geological time volcanism has shaped both climate and biological evolution, and volcanoes can affect human life, too, for both good and ill. Yet, even after much study, some of the fundamental aspects of volcanicity remain mysterious.
This Very Short Introduction takes the readers into the inferno of a racing pyroclastic current, and the heart of a moving lava flow, as understood through the latest scientific research. Exploring how volcanologists forensically decipher how volcanoes work, Michael Branney and Jan Zalasiewicz
explain what we do (and don't) understood about the fundamental mechanisms of volcanism, and consider how volcanoes interact with other physical processes on the Earth, with life, and with human society.
