New That was a click-bait headline. ;-)
Actual real numbers are here:



3. Anthropogenic Sources

3.1 Rice Cultivation

What we know:

Rice production may account for 10% (~30-60 Tg) of the total annual methane emission.
Since 1980, rice production has risen by over 40% through the combined effects of increased harvest areas and higher yields.
Over 90% of the harvested area is confined to Asia.


The university press release that your link cites says:

VANCOUVER, Wash. – Washington State University researchers say the world’s reservoirs are an underappreciated source of greenhouse gases, producing the equivalent of roughly 1 gigaton of carbon dioxide a year, or 1.3 percent of all greenhouse gases produced by humans.


It's an important source, but it's not what should be attacked first. Coal, oil, gas production, rice cultivation, etc., are much, much more important sources.

Cheers,
Scott.
New what do you have against rice? Stop growing rice what are we going to eat?
always look out for number one and don't step in number two
New We can make better rice that doesn't make as much methane.

Scientists said Wednesday they had created a rice variety with starchier grains that emits less methane, a step towards the twin goals of feeding more people and curbing global warming.

The cultivation of rice, a staple starch for billions of people, is also mankind's major emitter of methane, a potent climate-altering gas.

Methane lives for a shorter time in the atmosphere than carbon dioxide (CO2), the most abundant greenhouse gas, but traps far more heat radiated from Earth's surface.

Every year, rice paddies pump out 25 to 100 million tonnes of methane—the second-most important greenhouse gas at about 16 percent.

This means a high risk for the planet as rice cultivation expands to feed a growing population, said the paper, published in the journal Nature.

"There is an urgent need to establish sustainable technologies for increasing rice production while reducing methane fluxes from rice paddies," wrote the team led by Chuanxin Sun of the Swedish University of Agricultural Sciences.

New If . . .
. . it doesn't have good flavor, texture and cooking properties - they won't be able to sell it. It also has to be productive using rather primitive agricultural methods. Scientists often forget about all this stuff.

I was all upset until I remembered I'm on Verizon and it doesn't fucking matter anyway.
