PAS-PASS Workshop Casina Pio IV, 27 February-1 March 2017
On our 4.54 billion year old planet, life is perhaps as much as 3.7 billion years old, photosynthesis and multi-cellularity dozens of times independently around 3.0 billion years old, and the emergence of plants, animals, and fungi onto land, by at least the Ordovician period, perhaps 480 million years ago, forests appearing around 370 million years ago, and the origin of modern groups such as mammals, birds, reptiles, and land plants subsequently. The geological record shows that there have been five major extinction-events in the past, the first of them about 542 million years ago, and suggests that 99% of the species that ever lived (5 billion of them?) have become extinct. The last major extinction event occurred about 66 million years ago, at the end of the Cretaceous Period, and, in general, the number of species on earth and the complexity of their communities has increased steadily until near the present.

Today ClimateMatters.TV brings you Dr. Peter Wadhams, recorded at UN climate negotiations in Marrakesh, Morocco. Peter discusses some of the material contained in his current book “A Farewell to Ice.” Peter is an ‘expeditionary’ scientist and Emeritus Professor of Ocean Physics from Cambridge. His observations of the Arctic ice for over 4 decades makes him one of the worlds authorities on the subject.
Bud Ris is Co-Chair of Boston Green Ribbon Commission’s Climate Preparedness Working Group and Senior Climate Advisor to the Barr Foundation. Ris’ lecture was presented as a part of a week of climate change-related events called “Climate Week,” organized by the Harvard University Center for the Environment in cooperation with a wide variety of partner institutions across the Harvard campus. This week-long program gives the Harvard community, as well as the interested public, exposure to some of the best scholarship and thinking related to climate change at the university.
An epic nor’easter, a full moon high tide and a rising sea all conspired to swallow up Boston with an icy cold winter flood. What has been a somewhat rare event is believed in the coming years to become much more common due to the effects of climate change. Science correspondent Miles O’Brien reports on how Boston is preparing and whether it will be sufficient.
Reviewing archival video to see scientists making predictions based on early, primitive 1980s climate models. Did they play out? Modern observations show the evidence. Part of the “This is Not Cool” series for Yale Climate Connections. See more here https://www.yaleclimateconnections.or…

Travel video about destination Miami in the United States of America. Miami is a tropical, gleaming metropolis with palm trees, beaches, Art Deco, luxury and crime. Along with Miami Beach, it is at the centre of the expanding southern region of the American State of Florida and has both a highly developed economy, as well as a flourishing tourist industry. Miami Beach is a narrow island just off the mainland and Miami and is a leisure world of the young and beautiful and of the rich and famous. In 1915, millionaire Carl Fisher had a road constructed through the island’s dense and snake-invested mangrove forest, today’s Lincoln Road. The aftermath of a powerful hurricane once meant a new beginning, hundreds of hotels and apartment houses were built in Art Deco Style and today, they blend well with the local lifestyle. Since the 1950s, Virginia Key has been the home of the Miami Seaquarium, a marvelous world of marine life. It soon became world famous due to the incredible performances of its marine life and part of the TV Series ‘Flipper’ was filmed there. The Miami region is a melting pot of immigrants from Latin America and the Caribbean, a lively metropolis on the edge of the Everglades and the Florida Keys. A unique American cocktail of glamour, flamboyance and harsh reality!
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
