Climate - truthful information about climate, related activism and politics.

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 climate is really complex, and is the poster child for chaos theory. One of the weird things is that more snow storms and unseasonally cold weather is an expected result of global average temparature rises.

It's one of the reasons it's better to say "climate change" instead of "global warming", to help ease the confusion.

But see, scientists changed the messaging, which means that they don't know what they're talking about! Also, they used to be worried about global cooling! How can you trust someone that keeps changing their story when they get new information?!?

I love the term "scientists", because it's so poorly defined it can mean whoever you want it to mean.

My favorite is all the predictions were wrong.

We can’t ever figure out the weather accurately in a local region. So yeah, figuring out the global weather is going to much harder.

I don’t deny climate change. I don’t know if it man, the sun or something else. I have opinions but I think the debate is still. We need to first all agree things are changing which to me is obvious but we can’t get agreement on that.
