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.

Hi, not sure if this is the right place for this, but - I come to slrpnk.net to talk with people about solarpunk ideas and actions, but my dash is frequently filled with endless news stories. If I wanted to read upsetting news, I would... go read the news. Climate in particular has almost no discussion about climate change or actions we can take and only news articles. I've been thinking of blocking the community so that I don't have to sift through news stories to get to posts by members of our community. Does anyone else feel like this?

(Note: this isn't to say that I'm ungrateful for the folks sharing the news articles. I do appreciate it! I just feel that for myself, I'd rather focus on the possibilities that solarpunk has and human connection with others in this movement.)

On the one hand, news and information are important. We need them as a basis for action.

On the other hand, I feel that news are often shared with the hope that someone else will act according to the new information. This applies to scientists, journalists and also posters on social media. This is a very logical assumption. Unfortunately, the action part is sadly much smaller than we had hoped. However, I feel many people (especially scientists) get completely stuck in the logic that information leads to action and try to combat that by sharing even more information, researching for even more details etc.

Instead we should embrace action and invite others to join. However, this somewhat conflicts with the pseudonymity of lemmy. But it may be easier on other platforms, where people more easily share their real identity (mastodon, pixelfed, loops and their commercial counterparts).
