Rice Feeds Billions of People — but Its Role in Fueling Climate Change Is Growing
Rice feeds more than half the world. From terraced paddies in Southeast Asia to irrigated fields in China and India, it underpins daily meals for billions of people.
But the same flooded soils that help rice thrive also create ideal conditions for microbes that release climate-warming gases.
In a new study, ourteam ofenvironment andagriculture scientists found that greenhouse gas emissions from rice paddies have nearly doubled globally since the 1960s, averaging about 1.1 billion tons of carbon dioxide-equivalent emissions per year in the 2010s. That’s roughly equal to the annual emissions of 239 million cars.
This makes rice-growing the largest emissions source in agriculture outside of livestock, and rice demand is expected to keep rising.
OK, and?
Farmers have ways to reduce their rice crops’ emissions without lowering their yields. If every grower used the best currently available “climate-smart” options, we found that global rice emissions could be reduced by about 10% by midcentury. However, greater reductions are needed to slow climate change, which would require developing additional, more effective strategies.
And those are?
At the same time, rice farmers are using more fertilizers and organic amendments, such as straw and manure, planting more productive rice varieties and growing the plants closer together. The result is more rice but also more greenhouse gas emissions.
We found that one practice in particular – leaving rice stalks in the field after harvest and then plowing them into the soil to improve soil fertility – was responsible for about 18% of rice’s increase in overall net emissions since the 1960s. The reason: It increases the organic matter in the soil, which microbes then decompose, creating more methane emissions.
OK, so, make growing rice more inefficient. And, later on that is exactly what is recommended. How many people do the Warmists want erased, particularly in the developing world?

In its latest effort to narrow pathways to immigration to the United States, the Trump administration says it will crack down on attorneys who file fraudulent asylum claims for their clients.
US immigration enforcement flights are producing hundreds of thousands of metric tonnes of climate-damaging carbon emissions as officials shuttle unprecedented numbers of people to detention centers far from home and deport them to countries across the world.
In the hours after U.S. military forces spirited away Venezuelan President Nicolás Maduro on Jan. 3, Secretary of State Marco Rubio placed a call to Maduro’s second-in-command, Vice President Delcy Rodríguez.
Pessimism is probably “a bigger problem than climate change”, said the novelist Ian McEwan on Monday afternoon, as temperatures broke May records in the UK.
Budget constraints are forcing liberal-leaning states that spend their own money on healthcare for noncitizens to scale back that aid, as they grapple with federal Medicaid cuts and the expiration of federal subsidies that helped people buy Obamacare plans.
Fans, coaches and critics of the NCAA have in recent years lamented the intensifying corporatization of college football and basketball programs specifically, punctuated by a trend of top recruits and coaches jumping from one school to another, in many cases to chase more endorsement money or playing time.
