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 United States’ first “carbon-positive” hotel (meaning that it is supposed to sequester more carbon than it emits

I always thought "carbon negative" meant something removed more carbon than it emits / was used to produce it.

Or is it one of those " 'inflammable' means 'flammable' " kind of terms?

It's a neologism, rather like "inflammible" because "negative" is an awful word to use for marketing.

I'd say confusing people into thinking the opposite by changing the meaning of fairly established terms is also awful marketing.

They should just use a different word. There are plenty.

Did you know, these new gasoline engines are also “carbon positive”. The more you drive, the more carbon you deposit into the atmosphere! Everybody wins!

It does, like the same way a negative blood test means you don't have something.

But this language has probably been used, like the other commenter has stated that it's dumbed down for the stupid pond people

"Negative" sounds too negative.

[–] lnxtx@feddit.nl 2 points 2 days ago

I would like to pay negative bills.

It is greenwashing bullshit, of course. No such thing. Unless it's a hammock in a tree.

Insignificant, but cool. I didn't know about the anti-greenwashing legislation they mentioned until now, that's probably more significant.
