The Most Extreme Storms Yet
Guest Speaker: Joel Pomerantz
7:30pm, Thursday, Mar 19th, 2015
FREE at the Randall Museum, 199 Museum Way, San Francisco, CA 

Joel will share his research on the weather disaster that determined so much of what’s around you today. In early 1862 the sky dumped upwards of ten feet of rain in the mountains (about four feet in San Francisco). In the middle of that, there was a hard freeze for a week down to sea level. Thousands died. No previous research has done so much to connect the dots. Come learn about the widespread disaster that spanned more than four states (before all were states), changed the course of rivers, destroyed the California economy and brought in invasive grasses, among other stunning details.

SF Carbon Cycles, Humans & the Climate
Guest Speaker: John Wick
7:30pm, Thursday, Feb 19th, 2015
FREE at the Randall Museum, 199 Museum Way, San Francisco, CA 

John Wick, Co-founder of the Marin Carbon Project, is making great strides in organizing around soil carbon sequestration with everyone from the ranch house to the White House.Come hear what you can do, what the city is doing now, and how the Randall Museum will be part of a demonstration project on carbon cycling.

We’ll discuss the whole carbon cycle with an eye to making informed changes in our management of carbon: human nutrition, organic waste streams, soil health, water, wealth & economics, and carbon credit protocols.

Sky Phenomena
Guest Speaker: Joe Jordan
7:30pm, Thursday, Nov 20th, 2014
FREE at the Randall Museum, 199 Museum Way, San Francisco, CA 

Rainbow above the golden gate

Joe Jordan will come back with new material after having really wowed and inspired our audience with his slides on this topic in 1997.

Joe will show pictures of all kinds of atmospheric phenomena, including rainbows, haloes, glories, aurorae, coronae, mirages,
and the legendary (but real) “green flash”.   He’ll bring along some hands-on 3-D models (to go along with his descriptions
and explanations) that might help us understand what causes some of these things, and where and when to watch for them.

As an added treat, Joe will regale us with information and stories on a recent focus of his — the science, technology and politics, behind clean energy (“sky power to the people” — see his TED talk on it – shown below!) — including the scientific basis for a big public-art sculpture idea.

Ice Plants, Mattress Wireweed & Other Onslaughts
Guest Speaker: Lew Stringer
7:30pm, Thursday, Jan 15th, 2015
FREE at the Randall Museum, 199 Museum Way, San Francisco, CA 

Have you seen how much of our coastal parkland is now covered in succulent ground cover, hardy New Zealand vines, and just too many highly invasive species? Come hear Lew give us the low down on ground cover invasive plants. He’s been working with the Presidio Trust, and before that the Golden Gate National Recreation Area, to develop strategies to manage the various species that would take everything over if they managed themselves.

Living in the Plate Boundary and Through the Ice Ages
Guest Speaker: Tanya Atwater
7:30pm, Thursday, Oct 16th, 2014
FREE at the Randall Museum, 199 Museum Way, San Francisco, CA 

The geology and  landscapes of California are the results of a long history of plate tectonic interactions. The majestic granite walls of Yosemite, the rich agricultural soils of the Central Valley, and the wild-colored rocks of the Coast Ranges all reflect a long history of subduction. Our present beloved topography of dramatic mountains and sweet valleys reflect the evolution of the San Andreas plate boundary. In turn, all these features have been modified by sea level and climate changes during the ice ages. Using maps, landscape images and computer animations, Atwater will describe and explain all these geo-treasures.

You can read more about Atwater and her background here. In the 70s, she wrote about the origins and growth of the San Andreas fault, and contributed to our current understanding of a then nascent idea — it sometimes seems hard to believe that plate tectonics is a new idea! For a little teaser of what she has to show — see the video below…

SFPUC HQ as a wastewater treatment system
Guest Speaker: John Scarpulla
7:30pm, Thursday, Sep 18th, 2014
FREE at the Randall Museum, 199 Museum Way, San Francisco, CA 

The SFPUC built a new building very recently. John Scarpulla will tell us about how the new HQ building functions as a wastewater treatment system using an internal artificial swamp. The building is impressive in a lot of ways: consuming 32% less energy, 60% less water, and a 50% smaller carbon footprint than similarly-sized office buildings.

It is one of the first buildings in the nation with onsite treatment of gray and black water with an onsite “Living Machine” which reclaims and treats all of the building’s wastewater reducing per person water consumption from 12 gallons (normal office building) to 5 gallons.
