Series Title:  Earth's Core to the Clouds

Volcanoes, earthquakes, ocean currents are a few of the geologic forces that have shaped the contours of our planet for millennia. Today, our climate is rapidly changing.  Research presented in this series seeks answers as to why and how natural phenomena and human evolution have played a role.  Our journey from the deepest depths of Earth will culminate in a closer look at the trends happening in the southwestern deserts today.

Subduction, Earthquakes, and Volcanoes:  How They Shape our Dynamic Planet

Dr. Susan BeckPresenter: Susan Beck, Professor, Department of Geosciences

Subduction zones are sites on Earth where the largest earthquakes, tsunamis , and volcanoes occur.  They are locations where tectonic plates are recycled into the interior of the Earth and drive much of the dynamics and hazards of our evolving planet.

Earth's Greatest Mountains: the Rise and Demise of Extreme Topography

Dr. Barbara CarrapaPresenter: Barbara Carrapa, Professor, Department of Geosciences

Mountains such as the Himalaya-Tibet and Andes constitute the highest topography on our planet (with elevations up to 8,848 m: 29,029 ft) affecting biotic distribution and global atmospheric and oceanic circulation. For example collision between India and Asia in the early Cenozoic (~ 55 Ma) has allowed for terrestrial faunal exchange between the two continents; and uplift of the Tibetan Plateau and the Himalaya has formed the largest orographic barrier to atmospheric circulation blocking moisture from the south and creating the Asian monsoon. Similarly the Andes affect the Humboldt Current with impacts on global ocean circulation and create a large orographic barrier responsible for the South American monsoon. Yet climate in concert with tectonics has controlled erosion and shaped topography over geological time.

Earth's climate trajectory: past, present, future

Dr. Jessica TierneyPresenter: Jessica Tierney, Associate Professor, Department of Geosciences

Recently, carbon dioxide levels on Earth passed the 400 ppm threshold for the first time in human history. How do we know this, and how does the present and future climate compare to what the Earth has experienced in the past? In this talk we’ll examine how Earth’s climate has changed since the time of the Dinosaurs (the Mesozoic Era) and what drove changes between warm and cold climate states. As we shall see, these ancient changes in climate hold valuable lessons for present and future climate change, offering a glimpse of what to expect in a warmer world.
