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.

Also, in general, eating no or less meat and dairy can be a healthier diet https://gimletmedia.com/shows/science-vs/6nh87mb/vegans-are-they-right

But cheese is so good…

I’ve already swapped to oat milk, but cheese…

FYI, if they can produce plant based burgers that have the texture & tastes like beef, then l see no reason why they can't do the same with a plant based cheese.

Food is chemicals (chemistry)

They haven't succeeded yet. No good fake cheese, no good fake yoghurt, no good fake bacon

We haven't even done the much simpler chemistry of replicating photosynthesis (sunlight and CO2 to sugar)

@psud

Well then, if they can't make plant based cheese that tastes exactly like dairy cheese we're doomed (FFS)

Don't believe the losers that say science is impossible

"Photosynthesis"

Plants have evolved to do that already! That's also why it's far better for the environment to eat plant & fungi based diets. Less energy (fewer resources) is lost (used) by eating the plants inc. the milks that are made from plants. Compared to eating the animals that eat the plants
