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.

A wireless router consumes single digit watts of power. A tablet or mobile phone consumes 1/10 or less of that. Making a slice of toast and a cup of tea uses more power than both of those devices all day combined. This is another silly attempt to shift blame from corporations and billionaires down to consumers and everyday people. Don’t buy it.

Kind of like how a 1000 LLM prompts equate to a microwave running for a second.

The real consumers of power are corporations.

Like, if millions of homes all had a 55" 4K TV running 24/7, and decided to turn it off at the same time, that still only equates to 300MW/h.

Which is the same as ONE large factory.

We don't have energy shortages, we have distribution problems.

Honestly the amount of energy needed to print and put this ad probably costed more than every amount they save.

There is some truth to it, in that the data centers that host a lot of digital content are environmental catastrophes. But like, again, that’s the fault of companies, not the consumers. Companies could choose to optimize their websites better, choose to streamline their systems and minimize the amount of data they’re collecting on users. Choose to use solar power and batteries and eat the upfront capital cost (it would even save them money over the lifetime of the facility.)

But they choose to ignore all that and just boil lakes and chug methane instead.
