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:

A sustainable diet leaves room for two chicken breasts a week, study says (phys.org)

255 grams per week. That's the short answer to how much meat you can eat without harming the planet. And that only applies to poultry and pork.

Beef cannot be eaten in meaningful quantities without exceeding planetary boundaries, according to an article published by a group of DTU researchers in the journal Nature Food. So says Caroline H. Gebara, postdoc at DTU Sustain and lead author of the study."

Our calculations show that even moderate amounts of red meat in one's diet are incompatible with what the planet can regenerate of resources based on the environmental factors we looked at in the study. However, there are many other diets—including ones with meat—that are both healthy and sustainable," she says.

I like the bikelane analogy, actually.

It shows clearly that (a) yes you do need activism (like Critical Mass) and a few crazy ones that will bike regardless of the adverse conditions, (b) political will to shift towards bikelanes, (c ) wider adoption but also sustained activism to build better bikelanes (not painted gutters on the side of stroads, but protected lanes, connected with transit).

We definitely do not lack (a), but (c ) FOLLOWS (b). If you want to go from "just the crazies" to "everyone and their 5 year old", systemic change needs to be backed by very concrete top-down action.

Without very meaningful (b), telling people to change their eating habits while stuff is otherwise the same is like telling people to take their kids to school on bikes next to crazy SUV traffic: it's not happening.

Good. But until it becomes as cheap and easy for a family of 4 to eat vegan as cheaply, completely and easily as it is to not, let's not make finger wagging the political strategy for change. Nobody wants that.

Do you really think that beans, broccoli, lentils and all the vegetables, fruits, legumes.. are more expensive than meat? Don't forget that meat also has subsidies to lower the final price, so you are also paying in taxes this "cheap" meat.
