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.

  1. ublock origin doesn't block them
  2. tldr
  3. b12 supplements are fundamentally essential for folate defects
  4. nothing to comment on, you make vague assumptions and ad hominem attacks
  5. you simultaneously write it's complex, imperfect and full of corruption, but also that it's not unreliable. Pick a stance
  6. what dietary pattern fits the whole global population?
  7. I spent way too much time reading this. Despite being twins, the study shows the vegan group started the study much healther, with a healthier diet, eating less processed meat, with far lower LDL cholesterol. During the study the vegans were made to eat significantly less, and the non-vegan group was forced to eat more than they did before the study. The measures of success included fat loss and insulin again like I mentioned, a poor marker. Simply fasting or eating less would achieve the same results - which is exactly what the vegan group was made to do. There is nothing of value learned here.
  8. correctly set up RCTs with large groups would address the problem but AFAIK no one has ever succeeded
  9. you can eat a close to ancestral diet without living in the same place... your hyperbole and dramatisation is wild. I have visited several farms, none of which treat animals poorly. I'm sure some farms have horrific conditions and should be shut down, but that's unrelated to vegan nutrition and ventures into whataboutism

Thanks for the discussion but I am done
