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.

We’ve only had 1.3C of global average warming, but it’s enough to popularize the entire category of personal cooling devices. So when people say, “You won’t even notice 1C of global warming,” the market tells us that that’s absolute bullshit.

When I tell people that in the future, the rich will live in citadel orbiting a burning earth, paid for by selling oxygen, they call me a tankie.

@silence7 HVAC manufacturer Carrier already knows.

“Growing Demand Meets Increasing Urgency

As the world recognizes the increasing urgency of #ClimateChange and secular trends continue to increase the demand for HVAC and refrigeration products, Carrier is committed to aggressive actions that minimize our environmental impact and help address the most critical challenge our planet has ever faced.”

Pay to stay ❄️ cool ❄️. If you can.

Notice they barely mention refrigerants because they are planning to use HFOs to meet low GWP targets rather than only actually sustainable choice - natural refrigerants. HFOs are PFAS and we are already seeing environmental accumulation of PFAS (primarily TFA) directly linked to HFO use around the world. We need to shift to natural refrigerants now.

I like the fremenesque suit at the end. what a world.

What people actually have are vests filled with ice. Knew a couple of people who were canvassing in the Arizona heat wearing them.

I can't imagine they would last long. There is this device my wife used after surgery that runs ice water through a tube to a wrap on her recovering area on and off circulation so its only going 50% of the time. Had a huge resevoir I would empty water from and fill ice into. It was crazy how much ice I had to make and constantly replenish and she was in a comfortable envirnment resting in bed. Can't image how someone being active and out in the heat with something covering way more body surface area is going to have it last long and they would need to be near a constant source of ice.

It mentions the neck-coolers being ineffectual, but at least according to a Techmoan review I saw, the model he had was surprisingly effective.

Not that I disagree with the point of the article, which is that we shouldn't need this shit to begin with and only the wealthy first world nations will be able to afford them, but the tech itself does seem to work.

I'm very very hesitant to believe in most online reviews; the product manufactures pay for a lot of them.

[–] ProdigalFrog 1 points 1 month ago

Fair enough, but in my experience Techmoan has always been trustworthy in his reviews, he's not sponsored by the manufacturer.

Interesting article, worth the read.
