#methane

From the article:

Their metrics showed that — in addition to providing over 1.7 billion meals to 40 million people in need globally — food banks also diverted an estimated 1.8 million metric tons of carbon dioxide. By intercepting unspoiled food destined for the landfill, and redistributing food from local farms and wholesale produce markets, the 2023 report offered evidence that community-led solutions to addressing global hunger can also help protect the globe itself.  “Nearly a third of the world’s food is lost or wasted at the post-harvest, retail, and consumer levels, never reaching the people who need it,” the GFN team wrote in the report. “Food loss and waste proves costly for producers, takes up space in landfills, and emits harmful greenhouse gases, intensifying climate change.”

Reading this was one of those "oh duh!" moments for me. Despite being aware that food systems and food waste are major sources of emissions, I had mentally placed food banks in a "addressing non environmental problems" category. But of course, food banks make our food system more efficient and less wasteful by making the most out of the food we have already produced.

Seaweed is once again showing promise for making cattle farming more sustainable. A study by researchers at the University of California, Davis, found that feeding grazing beef cattle a seaweed supplement in pellet form reduced their methane emissions by almost 40% without affecting their health or weight. The study was published Dec. 2 in Proceedings of the National Academy of Sciences. This is the first study to test seaweed on grazing beef cattle in the world. It follows previous studies that showed seaweed cut methane emissions 82% in feedlot cattle and over 50% in dairy cows.

Underwater Ice Bubbles

Эстетика замерзших пузырьков метана.

Байкал — не единственное озеро, где поднимающийся со дна метан замерзает в ледяном покрове. Таких озер много — например, озеро Эйбрахам в Канаде.  Пузырьки метана поднимаются из глубин озер и скапливаются под поверхностью льда, после чего лед продолжает свое замерзание и при этом захватывает поднявшийся газ. Метановые пузырьки во льду бывают самого разного размера — от практически невидимых невооруженным глазом до крупных, доходящих до десятков сантиметров в диаметре и располагающихся друг под другом. Это все происходит слоями, поэтому в результате получаются причудливые россыпи, ниточки, шарики, лепешки и .т. д, уходящие в глубину вод озер, которые можно разглядывать бесконечно.

The aesthetics of frozen methane bubbles.

Lake Baikal is not the only lake where methane rising from the bottom freezes in the ice cover. There are many such lakes, for example, Abraham Lake in Canada. Methane bubbles rise from the depths of the lakes and accumulate under the surface of the ice, after which the ice continues to freeze and at the same time captures the rising gas. Methane bubbles in ice come in a variety of sizes - from practically invisible to the naked eye to large ones, reaching tens of centimeters in diameter and located one under the other. All this happens in layers, so the result is bizarre placers, threads, balls, cakes, etc., going deep into the waters of the lakes, which can be examined endlessly.

Canada has announced long-promised rules aimed at dramatically reducing methane emissions from the country’s oil and gas sector. The regulations, announced on Tuesday, lay out a path for Canada – the world’s fourth-largest oil producer – to cut by 2035 its overall emissions of the potent greenhouse gas by 75 percent over 2014 levels. They fulfil a promise by Prime Minister Mark Carney to strengthen Canada’s existing methane rules, but allow for a slightly longer target timeframe than the previous draft rules announced under Carney’s predecessor, Justin Trudeau.
