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 article lists Celcius first in the body of the text, with a Fahrenheit translation in parenthesis. The title then uses only Fahrenheit.

I assume the comment was meant to indicate, pick a unit of measure and stick to it. As opposed to Fahrenheit at the top, and Celcius in the body. Not to antagonize the use of Fahrenheit in general.

Also, stating that the use of Celcius is Euro-centric is a little awkward:

Motto of this decade is: faster than expected

TIL that the Fahrenheit scale was invented in either The Netherlands or England by an ethnic German born in Poland rather than in England by an English person born Englishly in England as I had always thought in spite of the German-sounding name 😆

The comment meant to indicate that @20cello@lemmy.world really really needs you to know that they are better than you.
