I’m not the greatest fan of Thunderf00t presentations either, but this comment of yours is almost comically missing the point.

Believing that we can change culture of nearly 200 nations is not going to happen “now”. And that is right there in the video as well.

Also, your numbers are way off the mark, far into the absolute bullshit sector. And that is according to pretty much all the climate science we currently have. Not even all of our agriculure amounts to “half of the man-made emissions”, much less animal agriculture.

Comment I was replying to was speaking of half of the man-made methane emissions, my bad. I’ll leave the numbers part below for anyone interested.

Agriculture in total is around 24% to 26% of the global emissions, depending on the source, but both numbers are still easily within error bars. That is a signifcant amount, but still not even close to the “half” you are claiming. But that’s still all agriculture, livestock, fisheries and pasture management are the largest part of that, sure. But that is still at around 30%-31% of the agriculture total. Taken the worst case, that is still 26% of 31% of 100%, which amounts to 9% (rounded up for good measure) of our GHG emissions in CO2 equivalent.

That is pretty fucking far from your “half”, which, for the uninitiated is 50%.

All this kind of completely bonkers numbers-fudging is doing is making it harder for people who actually do the math and understand the numbers to forward the message. The more people keep lying, the harder it is for actual scientists to convince politicians about the issue, since some asshole is ready to throw “they claim this kind of bullshit too!” -argument.
