The Dirtiest way to Store Carbon is the Best

- Adam Clare

One of the best carbon storage systems we can put into action to slow down climate change is right under our fight: dirt. Yes, the quality of dirt is on a spectrum between inert clumps and soil rich with with life. When it comes to using dirt to store carbon we want to create as much soil as possible because the better the quality of soil the better it is at capturing carbon. Plus, is we improve the quality of soil we will get better crop yields, happier insects, and all our plants will thank us.

As the largest terrestrial carbon sink, which stores three times more carbon than the entire atmosphere, soil offers a vast repository with immense, untapped capacity. Since the beginning of agriculture, food production has removed about half, or 133 gigatons, of the carbon once stored in agricultural soil, and the rate of loss has increased dramatically in the last two centuries, creating a large void to be filled. Restoring this carbon stockpile would sequester the equivalent of almost one fifth of atmospheric carbon, bringing greenhouse gas concentrations nearly to pre–industrial revolution levels and making soil less erodible. Let’s be realistic—we’re not going to restore 133 gigatons of carbon any time soon. But working toward this goal could be a centerpiece of a multifaceted plan to address both erosion and climate change.

Cities can Easily Reducing Salt Wasted on Roads

- Adam Clare

Transportation systems that put cars front and centre cause a lot of damage, we know this. But aspects of our cultural approach to getting around like, the reliance on road salt, are easily ignored. Every winter in North America we dump an unfathomable amount of salt on our roads which subsequently kills off wildlife. The costs of using road salt are high.

Cities are waking up to the damage years of salting their roads have done not only to local ecosystems but also to their budgets. Using road salt isn’t cheap and now cities are looking to alternatives, or at the very least, strategies to reduce the amount of salt they put on roads.

Area officials found that, pound for pound, brine was far more efficient than traditional rock salt. They could protect a lane-mile of road with a solution containing under 100 pounds of salt, roughly one third the amount used by rock-salt trucks.

Last, the towns switched to live-edge plows, which have flexible blades made up of multiple, independently moving sections mounted on springs. These state-of-the-art blades are more thorough than conventional ones. And starting with brine makes the plows even more efficient, says Eric Siy, executive director of The FUND for Lake George. If live-edge snowplows are like razors that hug the curves, brine is like shaving cream.

Yaupon, a North American Tea gets Revived

There’s nothing quite like a good cup of tea. Thanks to the efforts of tea fans in North America we all may soon have another tea option available to us. The only known native caffeine producing plant, yaupon, is a holly bush indigenous to the south east of the USA. Yaupon tea was lost to history due to colonization in North America, which has made a challenge to relearn how to harvest and use the plant. People who are reviving the use of yaupon are studying history to understand how best to prepare the plant. And yes, in North American tradition, it is already for sale.

As I began to learn more about yaupon, I was floored,” said White, “I just couldn’t believe that nobody knew about it.”

Though White quickly became fascinated with the holly’s history, he also realised that trying to brew an actual drink from it would be difficult, as there was no-one left to learn from. Guided by instructions he found in colonial diaries compiled in Dr Hudson’s volume about yaupon, White began picking the leaves and experimenting with roasting techniques. In a similar fashion, Falla tried roasting her first batch of yaupon in the family kitchen, discovering that she had a natural talent for creating a delicious nutty and buttery flavour.

Guided by a curiosity for botany and an interest in history, Falla and White unexpectedly found themselves on parallel journeys to revive the ancient beverage, with Falla starting Catspring Yaupon outside Austin, Texas, in 2013, and White founding Yaupon Brothers in Edgewater, Florida, in 2015. Today, yaupon continues to grow in popularity as additional startups have begun selling and promoting the historical beverage.

5 Ways We Can Improve Cities During the Pandemic

IKEA’s research and design lab in Copenhagen released a book this month on ways we can improve our cities. They start by recognizing we’re presently facing two global crisis: a pandemic and catastrophic climate change. Their proposals to address these two issues within cities is titled The Ideal City and they outright admit that top-down urban planning is inherently problematic. The goal of the book is to demonstrate that change is possible, it’s happening, and we can make the world better by improving our lived environments.

Making Cities Safer

This chapter proposes that in addition to lowering crime, cities need to protect their citizens against extreme weather events and provide a healthy environment that fosters physical and mental well-being. It highlights a small project that makes a big impact: the Tokyo Toilet, a series of 17 public restrooms designed by renowned architects in Tokyo’s Shibuya district. By incorporating colored glass that’s transparent when the lavatory is empty and opaque when in use, Pritzker Prize–winning architect Shigeru Ban’s design addresses two basic concerns people have with public toilets: cleanliness and how to know if someone’s inside.

Solar Panels are Undervalued by Traditional Markets

Solar panels are getting more efficient and the cost to produce them are decreasing by the day, already solar is cheaper than coal. Yet, due to previous policies and outdated economic models the real value of solar is underappreciated. While people wake up to the reality around the economics of solar the rest of us can call attention to the non-economic benefits of switching to sustainable power generation. Things like grid resiliency, if every home has solar panels then blackouts will become a thing of the past.

“Anyone who puts up solar is being a great citizen for their neighbors and for their local utility,” Pearce said, noting that when someone puts up grid-tied solar panels, they are essentially investing in the grid itself. “Customers with solar distributed generation are making it so utility companies don’t have to make as many infrastructure investments, while at the same time solar shaves down peak demands when electricity is the most expensive.”

Pearce and Koami Soulemane Hayibo, graduate student in the Michigan Tech Open Sustainability Technology (MOST) Lab, found that grid-tied PV-owning utility customers are undercompensated in most of the U.S., as the “value of solar” eclipses both the net metering and two-tiered rates that utilities pay for solar electricity. Their results are published online now and will be printed in the March issue of Renewable and Sustainable Energy Reviews.
