New modeling estimates that food production could add a degree Celsius to global warming. But it also points to powerful ways to make diets more ...

With data for so many different kinds of foods, Ivanovich’s team could then factor in population growth—basically, how many more people will be consuming these foods by the year 2100. “That’s not necessarily considering if that’s a realistic future, or if that’s really what the world is going to look like in 2100. With an ever-expanding population—and a ballooning middle class consuming more meat—humanity is spewing ever-more planet-warming gasses in its quest to feed itself. A new estimate shows just how bad it could get: By the year 2100, the global food system alone could contribute almost a degree Celsius of warming.

The global food system's greenhouse gas emissions will add nearly one degree Celsius to Earth's surface temperatures by 2100 on current trends, ...

"The majority of future warming from the food sector comes from the emissions of methane," said Ivanovich. The global food system accounts for about 15 percent of current warming levels, but only a third of national emissions reductions plans under the Paris pact include any measure to cut carbon pollution from agriculture or livestock. A major overhaul of the sector -- from production to distribution to consumption -- could reduce those emissions by more than half even as global population increases, they reported in Nature Climate Change.

Belgian and Dutch farmers are being sacrificed on the altar of climate change, losing their livelihoods as EU governments crack down on emissions of ...

The Dutch and Belgians are discovering it now. In trying to impose policies that discourage energy use, Western elites would condemn billions of people around the world to impoverished lives and hunger. But using less energy and making food more costly will leave people in these areas and around the globe worse off. Despite the billions of dollars spent by international aid organizations, many people lack food, modern energy, electricity, and running water. Thousands of Belgian and Dutch farmers are being sacrificed on the altar of climate change. But the number of hurricanes making landfalls is no greater than in the past. [Food prices rose 10 percent over the past year](https://www.bls.gov/cpi/), and climate restrictions will only send prices higher. Firms producing and relying on conventional fuels are finding it harder to get capital to expand, because they face higher rates to borrow. executive branch agencies are actively discouraging investment in oil, gas, and coal, claiming that such investments pose a risk to the environment. Ammonia is a key component of fertilizer manufacturing, and producing it requires natural gas. Will American farmers and consumers suffer the same ruinous fate?

A new study found that the majority of greenhouse gas emissions come from three major sources: meat from animals like cows, sheep and goats; dairy; ...

But reducing methane may be the most important goal of all. Those three sources account for at least 19% each of food’s [contribution to a warming planet](https://english.elpais.com/science-tech/2023-01-19/new-ice-core-analysis-shows-sharp-greenland-warming-spike.html), according to the study, with meat contributing the most, at 33%. Multiple recent studies and reports have recommended eating less meat in order to reduce greenhouse gas creation by animals raised for consumption. Ivanovich, a climate scientist at Columbia University and the study’s lead author. All emit large amounts of methane, a potent greenhouse gas with more than 80 times the warming power of carbon dioxide, in the way they are currently farmed. Then they scaled the annual emissions over time by gas based on five different population projections.

A group of international scientists reviewed climate literature to identify 41 climate feedback loops, 27 of which are accelerating global warming.

Some feedback loops may also be associated with key climate tipping points that could significantly disrupt the global climate system, researchers said. Of these, they discovered 27 amplifying feedback loops that are accelerating global warming and only seven that are slowing it. Another example involves the impact of wildfires, which are becoming more frequent as the Earth warms and drought conditions intensify.
