Farmers face the biggest problems, including nitrous oxides which emissions derive from animal urine and nitrogen fertilisers. NOs are reported as being 300 times more damaging than CO2 and remain effective as a thermal blanket for as long as CO2.

"It’s been accumulating in the atmosphere since the 1700s, and it’s powerful and persistent. One molecule of N2O has the same greenhouse warming power of 300 molecules of carbon dioxide. Once that N2O molecule gets into the upper atmosphere, it can stay there for more than 100 years before it’s destroyed naturally.

"Fortunately, air has about 1,000 times less N2O than carbon dioxide. But the rise in N2O has accelerated over the past two decades. And while we know where the excess carbon dioxide is coming from, we don’t know precisely how N2O is produced. That’s information we’ll need to know in order to curb future N2O production." https://www.whoi.edu/oceanus/feature/another-greenhouse-gas-to-watch-nitrous-oxide/

Farmers have been protected from the costs associated with the imperative to transit from nitrogen fertilisers.... as far as I'm aware there are now alternatives that don't have similar problems available as yet..... perhaps some of the farmers here can tell us more about this issue.
