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.

But we now appear to be living through the precise moment when the emissions that are responsible for climate change are starting to fall, according to new data by BloombergNEF, a research firm. This projection is in roughly in line with other estimates, including a recent report from Climate Analytics.

First of I wouldn't trust BloombergNEF for environmental sustainability estimates, only for business expansion advice.

Second would be that what the actual report of Climate Analytics says is:

In this report, we find there is a 70% chance that emissions start falling in 2024 if current clean technology growth trends continue and some progress is made to cut non-CO2 emissions. This would make 2023 the year of peak emissions – meeting the IPCC deadline.

This is a greenwishing NYT article, at best.

I'll take any sliver of hope. Also, they're not greenwashing anything? The article mentions a lot of relevant issues despite the seemingly positive statistic. We'll see soon enough. It's just a prediction anyway.

Just to clarify that greenwishing was not a typo:

The term “greenwishing” was coined in 2019 by long-time investment adviser Duncan Austin to characterize the failure of the “sustainable business” model to materially contribute to climate change mitigation...

I allowed myself to call it that way, because the author has incorporated in this text the business narrative of climate change.

Ah sorry, I misread it as washing.

Anyway, I think a positive expectation might be more motivational for some people than the constant fearmongering, which often leads to apathy. The largest hurdle for improving the environment isn't companies nor rich sociopaths, no it's apathy allowing the companies and sociopaths to get their way.

I want to believe that we can fix this, even if it's uphill for the rest of my life, in the best case scenario.
