There are still hurdles to overcome, but growing the seaweed industry in a state known for lobster could be a win for local fishermen, dairy and cattle operations, and the planet.

, it was just ~20% after accounting for the longer life of the cattle due to unpredicted slower mass gain with the supplement.

Unpredicted is wrong there, there are many substances, additives, and outright plants that can be added to ruminant diets to reduce GHG emissions and that usually has consequences. The animal farmers have known about these for a long time as it's part of the "technology"; sometimes the additives reduce weight gain, sometimes they cause harms; sometimes the plants taint the meat or milk.

They had hoped for no changes to development of the cattle and around 80% or higher emissions cut.

Yes, it's a huge failure.

a great starting point and a strong show of the value proposition

It's not. This has been going on for years.

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.
