Food Waste Progress

Food waste has been a perennial topic in these pages since we started covering environmental issues.  Thanks to Gastropod for point us to the future of this topic:

Black Gold: The Future Of Food…We Throw Away

Food takes up more space in American landfills than anything else. About 30 to 40 percent of food produced in the US gets thrown away, rather than eaten. What’s more, putting all that rotting food inside landfills produces a lot of methane, a powerful greenhouse gas. Continue reading →

First Drafts Of History

First reading of the day was this essay by a historian linked to once and referred to one time previously. And next up, the conscience of our generation compounds the idea, or rather pounds the idea home about who is writing the first draft of what will become our history, by defining reality as we see it today. I have listened to conversations with Daniel Yergin twice recently, and acknowledge being sucked into his expert definition of how to understand the fossil fuel world. I appreciate McKibben’s cold water on my face:

Who gets to define reality?

A search for the climate high ground

“Realism” is the high ground in politics—a high ground from which to rain down artillery fire on new ideas.

To wit, this week the New York Times profiled Canadian energy analyst Vaclav Smil, who—alongside others like Daniel Yergin—has long insisted that the transformation from fossil fuels to hydrocarbons must take a long time. Smil is a good writer and a smart historian; he’s documented the many-decades-long transitions from, say, wood to coal, and coal to oil as dominant energy sources. Continue reading →

Sensory Loading, Overloading & Unloading

Sounds Wild and Broken by David George Haskell
In early August, 2007 we arrived in a leafy suburb on the north side of Atlanta. We had spent the previous year living on this island, where doors did not have locks and during the daytime the only man-made sounds tended to be those of fishing boats coming and going. At night on that island there were no noises other than nature’s, including small waves hitting the shores and in summertime the crickets. On the first night in Atlanta I opened the window to let in the night air, and the sound of the superhighway, a mile or so away, was distracting enough that I had to close the window to sleep. It’s not that I had not appreciated the quiet of the island, but I was surprised by how much I had adapted to it. The opening of this book review, for these reasons, resonates with my own experience:

Sounds Wild and Broken review – a moving paean to Earth’s fraying soundtrack

David George Haskell’s often wonderful book explores some of the lost frequencies of nature – heard clearly again during Covid’s initial human hush

Lockdown was, among other things, a sudden collective experiment in volume control. Sound waves from the regular rush-hour thrum of cities usually penetrate more than a kilometre below the Earth’s surface. Continue reading →

Unexpectedly Amazing In Kerala

In our Kerala days we visited Wayanad many times, but I would remember if I had met Shaji. We would have sought his advice to expand on the agricultural initiatives at the properties we developed and managed.  Monika Mondal’s story ‘The tuber man of Kerala’ on a quest to champion India’s rare and indigenous crops brings back memories of unassuming neighbors doing unexpectedly amazing things:

Known as “the tuber man of Kerala”, Shaji NM has travelled throughout India over the past two decades, sometimes inspecting bushes in tribal villages, at other times studying the ground of forests closer to home among the green hills of Wayanad in Kerala. His one purpose, and what earned him his title, is to collect rare indigenous varieties of tuber crops.

“People call me crazy, but it’s for the love of tubers that I do what I do,” says Shaji. “I have developed an emotional relationship with the tuber. When we did not have anything to eat, we had tubers.” Continue reading →

Nature’s Energy Storage Potential

Thanks to Matthew Hutson for the article in the current edition of the New Yorker titled The Renewable-Energy Revolution Will Need Renewable Storage:

Can gravity, pressure, and other elemental forces save us from becoming a battery-powered civilization?

We need to vastly expand our energy-storage capacity if we’re to avoid climate catastrophe.

The German word Dunkelflaute means “dark doldrums.” It chills the hearts of renewable-energy engineers, who use it to refer to the lulls when solar panels and wind turbines are thwarted by clouds, night, or still air. On a bright, cloudless day, a solar farm can generate prodigious amounts of electricity; when it’s gusty, wind turbines whoosh neighborhoods to life. But at night solar cells do little, and in calm air turbines sit useless. These renewable energy sources stop renewing until the weather, or the planet, turns. Continue reading →

Climate Policies To Cheer On

I am heading to Ithaca tomorrow for family reasons, so the third item described in the story that follows is of particular interest. But every one of the items is worth reflecting on, in a news world without enough such stories. Our thanks to the Washington Post Staff who put this list together:

10 recent climate policies that could make a difference

Stories from the past six months that show what local and national policy change can look like

The most recent IPCC report makes it clear: There is no one silver bullet that can address global warming. Instead, nations, businesses, communities and individuals all have a role to play in helping to create a safer and more sustainable future. But without action from the world’s wealthiest countries, the nations and people who are least at fault for fueling climate change will be the ones who suffer the most, the scientists behind the report warn.

Tidal Power

Most of our attention to ocean water is focused on the climate,  and the few renewable energy stories with oceans featured have been about offshore wind projects. Today’s news corrects the deficit of attention to the power of tidal waves:

Could Anglesey’s tidal energy project drive a new energy revolution?

Experts say Wales has huge potential for generating renewable marine power, yet, so far, ambitious schemes have been ignored

On the stunning and craggy coastline of Holy Island in north Wales, work has started on a construction project to generate energy from one of the world’s greatest untapped energy resources: tidal power.

The Morlais project, on the small island off the west of Anglesey has benefited from £31m in what is likely to be the last large grant for Wales from the European Union’s regional funding programme. It will install turbines at what will be one of the largest tidal stream energy sites in the world, covering 13 square miles of the seabed. Continue reading →

Old Growth Forest Protection Schemes

Old growth forests matter for so many reasons. Not least, biophilic reasons. But at this moment, we rightly pay more attention to their value with regard to urgent climate issues. Maddie Oatman makes a good case in this Mother Jones essay:

Why Old-Growth Forests Matter So Much in the Fight Against Climate Change

Biden’s executive order to preserve ancient trees is a big deal—but it could have gone further.

Few experiences have rendered me as awestruck as the winter morning I spent wandering through a grove of ancient sequoias, their sienna bark glowing against the snowy ground. Continue reading →
