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.

I guess I may be naive, but I assumed compost collection would have become standard with garbage and recycling.

[–] silence7@slrpnk.net 12 points 3 months ago

A few communities have that. Most of the US doesn't. Large parts don't even have metal recycling.

You should check out the EPA's site on food waste (scroll down to the tables!)

It's really cool.

They also have breakdowns for metal, glass, wood, yard clippings, and other recycleables from years 1960-2018. Eye-opening numbers

Compost with weekly pick up while garbage is picked up every 2 weeks seems to be effective in my area. Since food waste smells quickly in the regular garbage most people use the compost to get it gone faster.

Others will complain about how stupid the city is wasting thier tax dollars and failing to collect their piling up stinky garbage all while refusing to recycle or compost any of their garbage.

In my city it is, and it provides natural gas for the city buses

What’s in the White House plan?

The White House says it will fund research into technologies that could extend the shelf life of food, like new seed varieties and better packaging.

The government will also invest in research to measure the “effectiveness of different consumer messages to encourage households to reduce food waste” and help students learn food waste prevention tips, including in school cafeterias, which can be enormous sources of food waste.

The Department of Agriculture says it’s also working with farmers, crop insurance agents and others to reduce on-farm food loss.

Yay. They found a way without impacting shareholder profits.

Keep edible food out of landfills by increasing shelf life? Presumably if the food is edible by the the time its getting to the landfill then shelf life isn't the problem.

[–] LwL@lemmy.world 1 points 3 months ago

If the food has longer shelf life, stores can keep the same amount of stock as now and sell everything before it goes bad.

Of course, the easy way would be for stores to not stock as much of food that is likely to go bad before all of it is sold, but then they make less money and also customers would cry that they sometimes can't get everything they want.
