Great documentary series. As a retired sharemilker there’s one thing missing from this series. Animal welfare and staff wellbeing. Maybe less of an impact on climate but definitely a huge impact on the general lifestyle we used to enjoy as a dairy farmer. Gone are the days where the family farm is the backbone of the industry, now it’s a situation where farmers find themselves being people managers and worrying about how they’re going to find people who want to do the job. Intensive dairy farming is not the way to secure a future for your family. Smaller scale, regenerative farming is the only way for future generations to succeed.
Methane emissions in NZ are short lived and they are also stable and that means that every emission does not cause any increase in atmospheric methane as each emission simply replaces constantly decaying atmospheric methane. Livestock emissions only produce half our emissions when you use the CO2 equivalent system which does not take in to account the cyclical nature of methane. The system is not scientifically credible. If you just take methane on its own because it is being emitted at the same rate as it is decaying, it is at net zero already. It is not causing any increase in atmospheric methane and therefore it is not causing any increase in global temperatures
Either you are not an expert in this area or you are deliberately misleading folk. Methane impacts do not vanish after 9-12 years they tail off over a much longer period , the drop in methane emissions from agriculture in NZ (which is estimated and likely misses emissions from land use change) has dropped by a very small margin. The short story is way to much is way to much. At a time when the head of the UN and the IPCC are telling humanity it is in great peril it is time to stop the smoke screens and find the courage to change.
Methane from cows have no impact of climate change? That is an extraordinary claim. Can you cite a credible source to back up your claims? “Extraordinary claims require extraordinary evidence” was a phrase made popular by Carl Sagan. Until you back up your claims, HItchens' Razor applies.
The figures quoted in the video for ruminant methane's contribution to NZ's overall warming potential are now out of date. The Climate Change Commission showed that there is now a steady downward trend in ruminant methane emissions in NZ and that these emissions only last from 9 to 12 years. Because farmers are not increasing stock numbers there is therefore no additional warming - in fact a slight cooling effect - occurring. The amount of ruminant methane lost in the atmosphere exceeds the emissions of new methane. Furthermore the video failed to show that farmers use significant amounts of Greenhouse gas - CO2 to grow grass and the growing amount of vegetation on farms. A fair analysis would show the net effects of ruminant emissions. Emitters of CO2 generally do not offset their emissions - farmers do. In fact many farms are 'carbon neutral' using as much Greenhouse gas as they emit. The method for calculating the warming potential of methane used earlier has found to be inaccurate. It focuses on volume rather than an ability to influence temperature. Scientists like Dr Myles Allen have shown in recent work that ruminant methane is only 25% as effective at actual warming as the official numbers circulating in NZ and used in this video. Blaming farmers for being slow to take action shows a concerning level of ignorance about what is happening and how historical data and theories are being questioned and overturned leading to the 'problem' being significantly less than is regularly claimed.
I don't think this video (and this doc serie) is "blaming farmers". It is pointing at an industry obsessed with profits and playing down all the devastating consequences of their actions. The system and the governments not acting to change it are to blame and are blamed here.
