Is Grass-Fed Beef Really Better for the Climate: in terms of climate-warming emissions, “it actually comes out no better — in fact, a little worse.”

    This article is so weird because its like, “go ahead and eat whatever beef you want because cows will still fart so its still bad for the climate.” Such a strange perspective.

    A cow’s diet does effect the amount of methane they expel. For example, studies have shown that letting them eat some kinds of white clover, or some strains of seaweed cuts emissions from cows. This research is important because people are going to continue to eat beef. You’d think the article would dive into that.

    And no mention of the exhaust from gas-powered machinery used to raise, harvest, spray, and transport the food raised to feed the cattle.

    Even just growing soy can contribute to greenhouse gas emissions. (Most corn and shoot is raised for animal feed).

    https://research.iastate.edu/2024/11/25/growing-soybeans-has-a-surprisingly-significant-emissions-footprint-but-its-ripe-for-reduction/

    Of course climate change contribution isn’t the only problem with pen-raised beef either.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
