These people are insane, every herbivore and ruminant since the beginning of time has emitted methane and the environment has coped and adjusted. The vast numbers of grazing animals wandering the plains of Africa and hundreds of millions of bison and deer in USA produced more methane than a few million domestic livestock. Much of what was once grazing has been taken over to produce crops and grazing animal numbers are now at historical lows.
There is nothing scientific about these decisions they are purely political, as is most of the global warming agenda.

Everybody who remembers his or her biology lessons from high school knows that bacteriae in an insect's gut or funghi on a forest floor produce more methane per kg of broken down biomass than bacteriae in a ruminant's gut... Huge tracts of former agricultural land became pasture for introduced cattle and native buffaloes when European germs killed most of the native American population in the 16th and 17th century, and global temperatures went sharply down. www.newyorker.com/magazine/2019/04/01/how-the-little-ice-age-changed-history |

Livestock farmers are being told they are destroying the earth because their animals are producing methane. Statements by academics and politicians like that in the article above telling them that methane "is responsible for around 30 percent of the global rise in temperatures to date", convinces naive citizens that action is needed and provides politicians with justification for imposing ridiculous taxes (and then paid for by everyone who consumes the animal products).
I contend that animal methane is responsible for 0.000% of global temperature rise for either of the following two reasons. I have not actually seen these reasons written anywhere and would appreciate any arguments you may have to counter them - let me know what you think.
Reason #1. The animal methane carbon cycle is circular.
The methane (CH4) produced by the cows is converted into CO2 & H2O in the atmosphere. This occurs relatively quickly (I think the CH4 in the atmosphere has a half-life of about 8 years). The CH4 is produced by the cow from the carbon in the cellulose and carbohydrate in the grass eaten by the cow. And the carbon in the grass is produced by photosynthesis from CO2 in the air. Hence the carbon is recycled from the air (CO2) to the grass (photosynthesis) to methane (digestion in the cow gut) to CO2 again (oxidation in the air). Unlike burning fossil fuels which transfers carbon from the ground to the atmosphere, the animal methane makes no net contribution to greenhouse gases and 0% impact on temperature.
Reason #2. Methane GHG effect swamped by the water vapour GHG effect.
The wavelengths of infrared light (IR) absorbed by methane are also absorbed by water vapour. Methane is 1.8 ppm of the atmosphere and water vapour is 15,000 ppm, so there is roughly 10,000 times more water vapour absorbing IR in the methane spectrum than there is methane. Methane in the atmosphere can double or triple or increase 100-fold and there would be no discernable change to the atmospheric greenhouse effect.
So, farmers should not listen to the drivel espoused by academics and politicians living off the "climate-crisis" industry and understand that they are doing more good than harm to the environment.

With summer ending in USA we should look at how much climate change is driving up their temperatures, because Australia has had a cold winter. Attachment Deleted |

Three cheers for global warming. |

The climate alarmists can get excited again the next solar maximum is coming quicker and harder than ever, it has nothing to do with CO2 but that won't stop them claiming it.  |
