“In My Day” – Sam Ellenport – Distinguished Amherst Graduate – Master BookBinder

Master BookBinder for Hartcourt Bindary speaks with “In My Day” http://www.inmyday.co

Samuel Ellenport was born in 1943, and was educated at Amherst, Brown University, and Oxford. A sometime teacher of history, he bought the Harcourt Bindery in 1971, and remains its owner. He is an active book collector, lecturer, and writer about the history of bookbinding. Among his writings is the Future of Hand Bookbinding published in 1993. He was instrumental in the establishment of the bookbinding program at the North Bennet Street School in Boston, and was Chair of the New England Chapter of the Guild of Book Workers, helping formulate chapter development during the 1970s and 1980s.

Why NO New Record-Minimum Arctic Sea-Ice Extent has occurred since September 2012: Part 2 of 3


Paul Beckwith

Published on Nov 29, 2020

The globe’s seven warmest years have all occurred since 2012, and Arctic Temperature Amplification has warmed the north at least 3 times faster than the global average. So WHY is Arctic sea ice still hanging on, and why hasn’t it set any new record September minimum since 2012? Since 2000, new record minimums were set in 2003, 2005, 2007, and then 2012; but nothing since then. Clearly, there simply must be some negative feedbacks going on, but what are they, and what mechanisms are in play? I have suggested that the wavy jet streams have brought ridges (warm, humid air) from lower latitudes as far north as the North Pole, even during the completely dark four month winter periods; meanwhile jet stream troughs have carried cool dry polar air as far as the equator, and that the jets have even crossed the equator to join with Southern Hemisphere jet streams. Both these ridges and troughs result in transferring heat from the pole to the equator. I have also made the argument that there is Atlantification (and Pacificication) of the Arctic Oceans, namely marine heat waves in the northern Atlantic and Pacific result in warmer waters entering the Arctic below the surface; since density of sea water depends on both temperature and salinity, warmer but saltier water is more dense than colder fresher surface water and can shoal and melt sea ice from below, and also delay it refreshing in the fall after the minimum extent has been reached.

In the new peer reviewed scientific paper on this topic by Jennifer Francis and Abington Wu, they argue that since 2012 the ice melt rates have been extremely high in the Spring and early Summer from high Sea Level Pressure (SLP), leaving both Arctic scientists and the public with bated breath, thinking that a new record breaking melt year and minimum September sea ice extent was sure to occur. Then, during each August/September an abrupt atmospheric shift has occurred, bringing low SLP, extreme cloudiness, and unfavourable winds for ice reduction, dashing all hopes of a new record minimum or even a Blue Ocean Event (BOE) with near 100% ice loss.

Francis and Wu argue that the mechanism for this late melt season slowdown is associated with jet stream splitting from diminished spring snow cover on northern hemisphere continents, which acts as a negative feedback that stalls late summer Arctic sea ice loss. I chat about the data and analysis that is behind their ideas.

Impossible Human – Episode 2 | Extinction Rebellion UK


Extinction Rebellion

Premieres Dec 8, 2020

Impossible Human: three conversations exploring change, vision, surrender, and living with Earth Impossible Human is a look into visionary cultures and social change. Delving into the potential of this liminal moment to ask how we might respond to our times and face into the future together. How can we light the path for the future and write a new story?

Hosted by Kary Stewart – Social Change Journalist.

Episode 2 – Tiokasin Ghosthorse a faculty member at Yale University’s School of Divinity, Ecology and Forestry, member of the Cheyenne River Lakota Nation of South Dakota, and an international speaker on Peace, Indigenous and Mother Earth perspective. Tiokasin asks what does it mean to live with Earth rather than on the Earth? He shares his sense of gladness at being alive now in this time of change, that She is in control. A deep far-ranging conversation about living from the heart, with Earth as our teacher. We think that going dark is bad for us but from the dark you see that light easier. If we’re always in the light you can never see the darkness. So positive and negative, I don’t know if that works anymore. The intelligence is what lies between the lines you see.

Delving into the potential of this liminal moment to ask how we might respond to our times and face into the future together. How can we light the path for the future and write a new story? Hosted by Skeena Rathor, Extinction Rebellion Co-Founder Vision and Co-Liberation Team Episode 3 – Bayo Akomolafe is a widely appreciated speaker, teacher, public intellectual, author and facilitator, globally recognized for his poetic, unconventional, counterintuitive, and indigenous take on global crisis and social change. Reflecting on our predicament Bayo wonders how our activism might reinforce the very system we are trying to dismantle. “Maybe there’s something powerful in not knowing where I’m from and maybe by not knowing where I’m from, I can claim to be from everywhere and nowhere at once. And that might be the kind of loosening that modernity needs in order to finally be composted”.
