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.

A new study shows that cutting down trees for paper, furniture, and fuel emits three times more carbon than flying.

I read the article and wtf. It's half between a pos article and useful info.

Logging generates a lot of carbon in the atmosphere, and after 75% of the article there is finally the reason : because we are burning it.

Wtf is this pos.

Yes burning wood emits carbon. Like any other burning thing.

But not directly for creating paper, furniture or building.

Tho there is some right in there, where yes wood can also be bad for the environment depending on how it is used, like burning a lot of paper in the trash. Incinerating furniture and other sources of waste...

Burning wood is still better than burning coal either way, since the carbon in wood originally came from the atmosphere.

And if that wood is something like a hybrid poplar, it's carbon within our lifespan (as opposed to old growth)

Kinda sorta. The conversion of forest land into commerical timberland on net moves carbon from the trees into the atmosphere. There's also a ton of fraud in that space around emissions claims.
