If we're seeking to halt climate change, it seems quite reasonable to look at effective measures for that. If decreasing methane emissions from landfill or farming might contribute, it seems odd to write those things off. This is partly due to the way we silo investment in the west: there isn't an organisation that is a single point of coordination and can make the tradeoffs logically. So for better or worse, we should try to make those tradeoffs wherever we can.

To riff off your programming analogy, climate action is like a program that requires a thousand complicated, interdependent functions to be written for it to do its job. Unfortunately in our analogy, virtually none of them ever speak to one another, so the process will be hard, some people will try to bypass other people's contributions - even if they're better - for want of understanding, and the whole thing will be an organic mess.

The difference is, if the program doesn't do what it says, that's kind of fine. If we don't meet or exceed carbon goals, many people around the world are likely to die.

I think that we'll have to do not one, two or three big changes, but maybe hundreds/thousands of small ones.

"Human activities contribute significantly to the total amount of methane emissions in the atmosphere. According to the Global Methane Budget, human activities account for about 60% of global methane emissions, while natural sources account for the remaining 40%.

To put this into perspective, it is estimated that human activities emit about 330 million metric tons of methane per year, while natural sources emit about 230 million metric tons per year. Human activities that contribute to methane emissions include livestock farming, waste management, and energy production, as well as other activities such as rice cultivation and biomass burning.

While natural sources of methane, such as wetlands and wildfires, are also significant contributors to methane emissions, human activities have increased the amount of methane in the atmosphere by about 150% since pre-industrial times. Therefore, reducing human emissions of methane is crucial for mitigating the impacts of climate change."
