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.

Life on earth:

[–] BaroqueInMind@lemmy.one 5 points 1 month ago* (last edited 1 month ago) (1 children)

Life on Earth will be fine.

There have been lifeforms that have survived multiple global extinction events over millions of years.

Humans won't. Which is why I stopped caring anymore about efforts to save ecosystems. Humans don't deserve this planet and will righteously reap what we sow.

Other life will go "Oh no, humans are gone... Anyways."

Whales, Elephants, and the other Great Apes are all likely to go too, and they don't deserve it. Humans brought this on ourselves, but the loss of peaceful intelligent life is a true tragedy.
