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.

Human ‘behavioural crisis’ at root of climate breakdown, say scientists (www.theguardian.com)

Record heat, record emissions, record fossil fuel consumption. One month out from Cop28, the world is further than ever from reaching its collective climate goals. At the root of all these problems, according to recent research, is the human “behavioural crisis”, a term coined by an interdisciplinary team of scientists.

“We’ve socially engineered ourselves the way we geoengineered the planet,” says Joseph Merz, lead author of a new paper which proposes that climate breakdown is a symptom of ecological overshoot, which in turn is caused by the deliberate exploitation of human behaviour.

An interesting read, but the solution of using our media to influence human behaviour into being pro-ecology ain't gonna work unless being sustainable is equally as profitable which it cannot be because sustainability is ultimately linked to less consumption of primary resources which is, contrarily, one of the biggest drivers for economic growth.

One thing the article highlights rightly is that all this focus on renewables should be secondary to humanity needing to simply consume less. It's a change we can make within a generation and would be far more impactful than any technological advances or deliberate population control.

Any idea how it could be possible for humanity to consume less?

Perhaps we need public campaigns from influential figures advocating for minimalism and simplicity. Or some sort of deeply spiritual second Renaissance...

There are historical examples of this happening for some resources (eg: forests in Japan)

First things first: make planned obsolescence illegal.

The vast majority of consumer products are designed to fail earlier than they have to, leading to a shitload of needless waste over which consumers have no real control.

Also, continue to limit single use plastics. Single use anything, but especially plastics.

And of course, phase out all uses of fossil fuel and derived products as viable alternative materials and processes become ready.

… need public campaigns…

Eh, no. We need actions not more virtue signaling and telling others they should be the first to start. If you want public figures to be involved there’s only one thing they can do, lead by example.
