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.

‘Hundreds’ of insurers ‘lose wifi’ as [climate] protesters cut fibre optic cables (www.insurancetimes.co.uk)

Per the activists:

The finance and insurance sectors of the economy have the power to make a significant difference. Without funding or insurance, fossil fuel companies cannot continue to operate or expand. Banks and insurance companies have clients other than fossil fuel extractors, they can continue to exist without this custom and so our demands aren’t unreasonable.

Banks and insurers have responded to campaigners’ demands by taking the tiniest of steps, however there is a serious discrepancy between what they are doing and what they must do in order to prevent catastrophic levels of global warming.

Now we are escalating to demonstrate that we – the public – will not accept this institutional and corporate support for climate breakdown.

That depends a fair bit on how corporate networks are set up. It's very easy to have a central authentication server that the base station can't reach anymore, so nobody can connect to the corporate wifi.

But the AP is still broadcasting so the WiFi never left it just won't provide data. Previous post is poking fun at bad journalism and oversimplifying the facts of the story. They cut data lines.

Not if it's PoE.

There is no such thing as Fiber PoE

Ah, I missed that. My statement would only hold true if someone specifically cut the Ethernet cable between the AP and whatever was supplying PoE.
