The Keeling Curve at 60: A Portrait of Climate Crisis

by

What the Keeling Curve shows, then, are two separate but connected rifts in Earth’s metabolism. First, an increase in total CO2 that breaks with at least 800,000 years of history. Second, increased CO2 is changing the way that plants absorb and emit CO2, and that in turn is altering a seasonal cycle that has likely been unchanged for hundreds of millions of years.

Guess Who’s Coming for Dinner

by

We have proposed a policy that would allow more sales of fresh homemade foods made in home kitchens with reasonable food safety requirements (such as safe food handling training, kitchen inspections, sanitary standards) and with the important condition that only certain types of legal entities could operate a web application or web platform that promotes sales of homemade food and takes a cut of each transaction.

The Curse of Bigness

by

There is, of course, a caution for our species in Pig #6707. When an organism grows beyond its design, nature will determine it to fail — a fact of life, in the strictest sense. Nowhere in evolutionary theory is hypertrophic growth posited as the key to success. What is key is optimum size, what we’d more accurately call right size.

How ‘Shared Socioeconomic Pathways’ Explore Future Climate Change

by

Over the past few years, an international team of climate scientists, economists and energy systems modellers have built a range of new “pathways” that examine how global society, demographics and economics might change over the next century. They are collectively known as the “Shared Socioeconomic Pathways” (SSPs).

Pre-Traumatic Stress Disorder and the Imagination

by

I was intrigued as to what impact living in a state of ‘Pre-Traumatic Stress Disorder’ might have on the human imagination, on its ability to flourish, and to imagine the future in positive ways.  Are we all, to one degree or another, living in a state of ‘Pre-Traumatic Stress Disorder’?

An Eco-Futurist Miscellany

by

More on organic farming, trade-offs, energy futures and small-farm definitions in this post. Veritably, it’s your one stop shop for a pick ‘n’ mix of eco-futurism…partly because indeed I have a few addendums to report on recent posts, and partly because despite my flippant recent remarks, I’m a bit too busy on the farm and on other things just now to put together a properly structured post.

The Road to the Seneca Cliff is Paved with Evil Intentions. How to Destroy the World’s Forests

by

With the era of cheap fossil fuels coming to a close, what’s left as low-cost fuel is wood and that had to be the target of the next wave of exploitation. Naively, I was thinking that the rush to wood would have taken the form of desperate people moving to the woods with hand-held axes, but no, in Italy it is coming in a much more destructive way.

Designing for a Better Society: How Tiny Houses can Have a Huge Impact

by

With IMBY we wanted to answer the question of how, starting from design and production methods, we could build a house that could foster social integration and civic engagement in a sustainable model. And this can only be done by empowering the people.

Cultivating Place: Refugees and Urban Gardening in Baltimore

by

There’s a difference between simply settling somewhere and finding a home. Refugees are faced with this reality every day — among new neighbors in a new city, building a sense of belonging is no small task. Working to create a place for oneself is a bold act of hope for a new life. So, what can public spaces do to help create a sense of place for refugees?
