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.

Good riddance. I could always tell how inefficient those bulbs were, simply from trying to touch them to change the bulb. All that heat is wasted energy.

Plus there's a lot of neat things we can do with the new LED bulbs, including adding Wi-Fi circuits to make them smart bulbs. And the price of those LED bulbs is dropped so much, I don't even really worry about the price difference anymore.

I just found out that my mother has 6 or 7 gigantic moving boxes full of incandescent bulbs in her self storage container.

She tells me they will be needed once the led bulb conspiracy fails. And that they will be worth a lot of money, enough to pay for her retirement.

I can't even

Wow, I'm sorry. What are her thoughts on flatscreens?

Do the 30 unopened boxes of 3D TVs answer your question?

"Oh, is that so mom? In that case I'd be happy to take over that pesky 401k from you. It must be so annoying managing it anyways now that you have the bulbs, right?"

My brother has been hoarding them for years for the same reason.

Meanwhile, I occasionally see boxes of slightly used bulbs on the curb as people upgrade

including adding Wi-Fi circuits to make them smart bulbs

That's how you can get your very own botnet, courtesy of some guy in China. Most of these shitty IoT crap never get any updates, and will probably serve most of their life as easy access points into your LAN.

I quarantine my IoT stuff in their own VLAN. They should be treated as untrusted devices, because they are, same as any BYOD network. Hack away!

I understand why smart home crap is the way it is, but can't we just re-wire houses so I can have all that stuff be peripherals to a central computer I can keep up to date or rip out and replace with one I trust? make powerline ethernet ones for currently existing homes and have data ports be a part of new electrical codes

Here we heat our homes 70% of the year, I wonder, does that mean the heat was not a energy loss during that time?

[–] [email protected] 2 points 1 year ago

Nope. Same with things like GPUs in winter. OTOH, if you are using AC to cool a place, then you should factor in the cost of cooling into the cost of running the bulbs.

[–] [email protected] 1 points 1 year ago

hypothetically, no. this assumes you were going to use electric resistive heating instead and the outside temperature when you used them was about when you used the bulbs. overall it's better to just get efficient bulbs anyways so you aren't wasting energy in the summer. I delayed replacing my last CFL because of this

honestly I'd rather a sort of dumb bulb that has dynamically changeable RBG and color temp settings but no wireless features and receives marching orders form a central smart home computer, versus the currently available solutions. I mean there isn't an Ethernet port at every light socket but I don't just want to litter my home with cybersecurity nightmare, proprietary, not easily interoperable random IOT trash.

I'd rather the hardware scattered around be as dumb as possible to do the fun stuff and be only connected to one general purpose computer I can configure and control to my liking. I can keep one PC up to date versus dozens of light bulbs and whatnot, I can insist on fully FOSS so the NSA isn't spying on me through my fucking light bulbs, I can remotely control it with SSH, etc.

you'd have to make an open standard for home wiring to make it work (can we have ethernet in every room for general purpose usage too while we're at it?) but one could jerry rig something with ethernet over power line I'm sure
