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.

It’s 90 degrees Farenheit (32°C) in the Arctic right now | The Arctic is heating faster than the rest of the planet. New data illustrate how dire that is (www.scientificamerican.com)

I grew up in Cleveland, and not once in my entire life did we ever have problems with CANADIAN wild fires. It's all wet up there, I didn't think anything could burn. Now it's a regular thing.

That's not normal.

Yeah we’ve been having dust storms like abnormal ones. We barely will get them and this year we’ve had multiple it’s been dusty all week. It makes me irrationally pissed off… except it’s not all that irrational. Fuck anyone who has a part in all of this.

Imagine how I feel in mother fucking Cincinnati.

The speed in which the talking point became "Everything has always been like this" to conservatives is mindboggling.
