The impact of ruminants on climate has been overestimated by a factor of 3 to 4, according to Prof. Dr. Dr. habil Wilhelm Windisch of the Technical University of Munich.
Going without beef burgers is not going to impact the climate anywhere near as much as some like to claim. This is even confirmed by the IPCC (see below).
Hat-tip: Klimaschau
Climate alarmists and closet vegetarians like to claim that methane produced by cows plays a huge role in climate change, and so people need to eat much less beef and other meats from ruminants. Bill Gates even wants people to turn to fake, “synthetic meats”. But it’s all mostly hype and hysteria.

Near 5%, not 20%
According to Prof. Windisch, as reported by the Bavarian Agricultural Weekly News of November 25, 2021, “The role of ruminants with regards to climate protection has up to now been overestimated by at least a factor of 3 to 4. An enormous climate contribution to climate warming has been falsely attributed to ruminants: 15 to 20%.”
That means in reality the so-called contribution is closer to just 5%.
Moreover, according to the Klimaschau, the number of ruminants in Germany has not risen, data show. In 1873, Germany had a total of 16 million ruminants. But in 2010, that number was down to 13 million.
Also, whatever methane that cows do emit ends up getting broken down in a matter of just a few years, the Klimaschau reports. Thus the system remains in equilibrium and so there’s little impact on climate.
Confirmed by the IPCC 6th Report
According to gvf Agrar: “It often goes unmentioned that the climate gases from agriculture come from balanced biogenic cycles and not from fossil fuels that transport additional CO2 into the atmosphere. This was also stated by the Intergovernmental Panel on Climate Change in the first volume of the sixth IPCC Assessment Report.”
Off topic, but better late than never
The Guardian: Polar bears found thriving despite lack of sea ice offer hope for species.
Polar bears have become the furry face of the climate crisis, with experts suggesting the animals could be all but extinct in a matter of decades as the Arctic sea ice they hunt from melts away.
But now researchers say they have found a group of them in south-east Greenland who are surviving despite a lack of sea ice for much of the year.

I agree that it is mathematically possible for something to “impact climate change” to an extent, but when that climate change is so very very slow and benign I refuse to worry about it, and so should everyone else!
Cows graze or eat hay and grain supplied to them. In the many millions of years before there were extensive cattle herds for human consumption, what ate those grasses and grains, or whatever grew in their place? Did those creatures not produce methane? Bison and antelope in N.A. or the multiple grazing species of Asia and Africa? Not to mention smaller animals like prairie dogs and insects.
Its actually more like “half-life of methane in open atmosphere exaggerated by more than 1700%” as it oxidizes pretty quickly and a large portion of the “detected atmospheric methane” comes from local sources to the sensors and is amplified by assumptive BAD statistics to represent a cow 800 miles away.
It will take one molecule of CO2 extracted from the atmosphere to produce each molecule of CH4 generated by ruminants. Since CH4 is much lighter than most of the other atmospheric gases – the same as water vapour – then it will rise rapidly through the atmosphere.
I don’t think a factor of 3-4 is the whole story.
Just please keep the brown cows, I really like chocolate milk.
And the small ones…I like cream.
Business as usual, how much is methane projected to run up global temperature by the end of the century?
That question is never answered by Climate Science, never asked by the press, and ignored by policy makers.
What’s sad is that in some rural communities, local youth, often drunk and bored, will find a cow and push her. Once the poor cow reaches a tipping point it’s often very hard to save her.
However, the calculations should reflect that once the cow has tipped, it probably won’t be producing any more methane.
More like zero. Its absorption band is saturated by water vapour.
And in more warm fuzzy news it seems some poley bears may escape the dooming due to Donald Trump and Scott Morrison-

Providing the bears don’t fart or burp too much of course.
So you’re saying it is MOOt?
This overestimation is just another cover for the globalists intention to increase their herds, on their massive US land, after they’ve completely removed meat from our tables and forced their fake meat as the only alternative. It’s not rocket science to understand this when they tell us in our face every day what their plan are.
