Peter Ward is Professor of Biology, a Professor of Earth and Space Sciences, and Adjunct Professor of Astronomy at the University of Washington in Seattle. He is Principal Investigator of the University of Washington node of the NASA Astrobiology Institute, which involves the leadership of over 25 scientists studying the probability of finding life beyond the Earth. He is also Senior Councilor of the Paleontological Society, and was awarded an Affiliate Professorship at the California Institute of Technology.
Since his PhD in 1976, has published more than 140 scientific papers dealing with paleontological, zoological, and astronomical topics. He discussed the state of the planet including climate change, melting ice caps, asteroid impact, dying oceans and mass extinction.
In the first half, Professor Peter Ward discussed his studies of planetary science, Earth, and its turbulent changes, as well as alien worlds. As sea level rises, this creates higher temperatures as the oceans expand.
Prof. Peter Ward () joined Ian Punnett for a discussion on how the BP oil spill in the Gulf will impact the delicate ecosystems of the world's oceans, and potentially trigger a series of events, including global sea level rise, that could devastate our planet
Live from Manila, Art Bell returned for a discussion with Prof. Peter Ward about his on mass extinctions and the self destructive nature of our planet, as well as the possibility for life in our solar system and beyond. Saturn's moon... More »
Appearing during the first three hours, Prof. Peter Ward, the author of Under a Green Sky, discussed his latest work on hydrogen sulfide extinctions, and how we are creating the circumstances for extinctions in the future. His research has connected past mass extinctions and global warming. Greenhouse gases and the melting of the ice-caps could create a dangerous situation where the ocean... More »
Investigator for the NASA Astrobiology Institute, Prof. Peter Ward discussed his new book, Out of Thin Air, which shows how fluctuating oxygen levels have contributed to mass extinctions and evolutionary changes over millions of years.
Peter Ward, an investigator for the NASA Astrobiology Institute, discussed his new book Life as We Do Not Know It, which ponders the possible existence of alien life. Ward believes that scientists need to expand their classifications of what constitutes "life" and include such forms as viruses.
Prof. Peter Ward, the author of Gorgon, shared his research into mass extinctions and climate change. A "Great Dying" took place 250 million years ago, he said, that was brought about by global warming. Volcanic events in Siberia added more carbon dioxide into the atmosphere, making the temperature hotter but reducing the oxygen. The air became so thin during this time, that it... More »
