Climate - truthful information about climate, related activism and politics.

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.

The meat and dairy industry is not 'climate neutral', despite some eye-catching claims (theconversation.com)

Where did they say to not do any other action? We have to address both fossil fuels and emissions from the meat industry if we want to meat climate targets. We cannot afford to ignore either

even if fossil fuel emissions were eliminated immediately, emissions from the global food system alone would make it impossible to limit warming to 1.5°C and difficult even to realize the 2°C target

To reduce emissions from the meat industry, most of that is going to have to come from reductions in meat consumption. The process itself is just quite inefficient

If I source my beef or lamb from low-impact producers, could they have a lower footprint than plant-based alternatives?The evidence suggests, no: plant-based foods emit fewer greenhouse gases than meat and dairy, regardless of how they are produced.

I wasn't talking about the article, I was talking about online discourse. Whenever climate has come up, it's almost always focussed on meat only in recent times.

We know plant based emit fewer emissions. We know red meat produces more than other meat such as chicken. We do need to make progress on emissions, and that can be cutting down meat consumption and also switching from red meat to chicken. If you eat red meat 7 days a week, and have 2 days without, and 2 days chicken instead, you're making inroads on emissions. Why is there a fixation of veganism? That was the comment I was responding to. I think it has less about the environment and more about vegans who are using the climate to further push their own personal agenda.
