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.

Study on their greenhouse gas emissions and climate commitments

With this study, we are providing for the first time a calculation of the GHG emissions from the ten surveyed slaughter and dairy companies in Germany, including discussing their general climate-related obligations – such as those from sustainability reporting in the course of the Corporate Sustainability Reporting Directive (CSRD).

We show, among other things, that the emissions of the ten most selling slaughter companies and the ten highest-grossing dairy companies in 2022 corresponded to around 61% of the emissions cast in Germany in Germany in the same year. If the opportunity costs are taken into account in the calculation, then the issues of the companies will even increase to 1.5 times the passenger car emissions.

We also take a closer look at previous climate protection-related self-discreet data from the two market leaders, Tönnies and DMK Deutsches Milchkontor, and we also come to the conclusion that these two companies in particular still have to improve significantly in terms of completeness, transparency and coherence.

Can't wait for cowless milk production to take off.

It already did, well it is not “milk” exactly, but it tastes correctly and can be used identically in the kitchen 😇

I was thinking of the identical chemical compound to cow milk, made by yeast, with significantly lesser ecological impact.

That would be amazing for cheese production!

Precision fermentation, is the term, I believe
