"For the first few years after it has been released into the atmosphere, a given quantity of methane will have a much stronger global warming impact than the same amount of CO2. The standard metric for equating the two gases, Global Warming Potential (GWP100), currently estimates that over 100 years a kilo of methane has 28 times as much global warming effect as a kilo of CO2, or 34 times as much if you take into account certain feedback mechanisms. ".
Sorry my friend - but that's a big enough anti-dairy slam-dunk there already. The rest is desperate pro-dairy hair-splitting motivated by self interest.
