In a recent report, a panel of retired generals and admirals warned that a shortage of fresh water would emerge as “a growing factor in the world’s hot spots and conflict areas.”. The percentage is lower in the United States in part because our overall greenhouse gas emissions are so much higher than other countries: In the United States we emit 16.5 metric tons per person per year compared to a worldwide average of about five metric tons. And these 1,300 pound (average weight for both a beef and dairy cow) animals eat a lot. The result is a large amount of methane being introduced into the atmosphere. In the era of climate change, water stress and its downstream consequences are drawing greater attention these days, including from American military analysts. Methane has a global warming potential recently estimated as 35 times that of an equivalent mass of carbon dioxide. According to the latest thinking, though, farming is responsible for the equivalent of 574 million metric tons of carbon dioxide emissions in the United States each year and 56 million metric tons in Canada. Let's start with how and why cows produce so much methane gas. According to researchers at New Zealand's largest Crown Research Institute, AGResearch, up to 95 percent of the emissions comes from the cow's mouth rather than its behind. Cows vs Cars According to the United Nations, agriculture is responsible for 18% of the total release of greenhouse gases and cattle are a major contributor to this figure. But cow burps are worse for the climate. “No matter their differences, previous administrations agreed on at least one thing: Countries must be transparent about their emissions, as well as their actions to address climate pollution, and should report on these issues regularly and comprehensively,” Nathan Hultman and Paul Bodnar, two Obama administration climate change officials, wrote in a recent op-ed in The Hill. In 2010, the United Nations proposed a "global levy on livestock methane emissions," or as the press dubbed it, "the fart tax." We plan to write more about meat, agriculture and climate change this year. The United States shares its laggard status with 13 of the 44 wealthy nations required to submit biennial reports. Livestock are responsible for 18 per cent of the greenhouse gases that cause global warming, more … The impact of agriculture, a category that includes everything from growing lettuce to raising livestock, is tricky to express because the gasses produced — mostly methane and nitrous oxide — have much more warming potential than carbon dioxide but also dissipate more quickly. It’s probably a safe bet that the report, when and if it comes, will be quite different from the Obama administration’s final update. Why could this potentially be bad? Methane gas emitted by cows and other livestock does have a significant impact on the amount of greenhouse gases in our atmosphere, which are the main culprits behind climate change and global warming. Livestock is the largest source of methane gas emissions worldwide, contributing over 28 percent of total emissions. In fact, unlike the ratios on a global scale, in the United States livestock is only the third largest contributor, behind the mining and transportation of natural gas and rotting landfill waste. By Lisa Friedman, Kendra Pierre-Louis and Somini Sengupta. With an estimated 1.3 to 1.5 billion cattle in the world today, this adds up fast. Cows and bogs release methane into the atmosphere, but it's by far mostly human activity that's driving up levels of this destructive greenhouse gas. So far, results have been positive. This grass lacks the nutrients and is difficult digest, which causes even more methane gas to be expelled from cows. Livestock are responsible for 18 per cent of the greenhouse gases that cause global warming, more than cars, planes and all other forms of transport put together. Some non-ruminants — like pigs, horses and mules — also release methane, but not as much. This didn't pass… but it is something that has continued to be discussed. These calculations of livestock emissions exclude the fertilizers used to grow food for livestock and they typically don’t look at alternative-use scenarios, like what would happen if we removed cows from grasslands and let wild ruminants like bison and deer take over. The Inventory team is rounding up deals you don’t want to miss, now through Cyber Monday. Shrinking livestock’s carbon hoofprint worldwide is a bigger challenge. We’d love your feedback on this newsletter. Several of these microbes create methane gas as a byproduct. Just think of Somalia, Nigeria and Syria. And that is putting it lightly (and not even counting the billions of chickens and pigs). The Trump administration has blown past a Jan. 1 deadline to update the United Nations on America’s progress toward cutting planet-warming greenhouse gas emissions and preparing for the consequences of climate change. The global problem Shrinking livestock’s carbon hoofprint worldwide is a bigger challenge. This regurgitated food is called "cud" and the animals chew it again to help further break it down to make it easier to digest. The New York Times climate team emails readers once a week with stories and insights about climate change. Two-thirds of those gases are directly emitted by ruminants: animals like cows, buffalo and sheep that use bacteria in their stomachs to ferment food. Since the turn of the 19th century, methane gas emissions have increased by 150%, according to NASA's Goddard Institute. In the United States, 42 percent of agricultural emissions come from animal agriculture. Methane is increasingly drawing attention from researchers because its worldwide levels have doubled in less than 10 years after remaining flat since the 1990s. China’s next biennial report is due next year, though a broader progress report from China was due in 2016 and has not yet been submitted. At times, forest cover is cut down to create pastures for cows, which again harms the environment and contributes to global warming.
