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 changing faster than we predicted. But it is following the same trends that our models have predicted. Either way it's alarming that we are all just business as usual. If the ocean ecosystem collapses, we're in serious trouble. And it will wreck absolute havoc on our current weather patterns.

It already has.

Record rain and snow in some regions, record drought in others; stronger hurricanes and typhoons. Japanese blossoms coming weeks earlier despite a millennia of records indicating it should come later.

When a large majority of the pollution isn't on the people but corporations and being blamed on the people is there really anything we can do besides trying to get laws passed? In the US at least that's improbable since the corporations doing this are giving money to all law makers and probably the judges too.

It prominently features a quote from Gavin Schmidt. Readers who prefer to get a more scientific view of the story can see his thoughts on the topic directly at realclimate.org.

Well, we can pretty much gather as much. A decade ago, two decades ago, the warning was “if we don’t act, in 100 years the world will be in trouble,” and then it went, “if we don’t act fast, we will see catastrophic effects within the next generation” to “this is happening at an alarming rate.”

And in case no one’s noticed, we’ve barely slowed down emissions, if at all. Greenwashing has had a profound effect and people think we’re doing a decent job, on our way to “net zero,” but we are digging a much deeper hole, really fuckin fast.
