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

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

"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?"

Big Lightbulb pushing their agenda with more cost efficient lighting :/

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 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

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

I'm assuming heat lamps for reptile enclosures are also exempt. It still kind of sucks because home incandescent bulbs were just as good for heat and a lot cheaper.

[–] silence7@slrpnk.net 3 points 1 year ago

I don't believe heat lamps are covered by this. Just bulbs for making visible light

[–] kozy138@lemm.ee 2 points 1 year ago (5 children)

Won't matter when lightblub manufacturing companies all agreed upon limiting the lifespan of bulbs to increase turnover.

There are incandescent bulbs that still work from over 100 years ago. Modern bulbs die with less than 10 years of use. Both incandescent and LED. But this new law will, of course, increase LED bulb sales. I'm sure no politicians have increases their GE shares before this.

This decision is about the energy efficiency of the bulbs. Incandescent bulbs turn almost all the energy they consume into infrared light and heat. LEDs turn most of the energy they use into light.

[–] gregoryw3@lemmy.ml 16 points 1 year ago (1 children)

Technology Connections just released a video about this. Those 100 year bulbs (and long lasting ones) used more energy and produced too little light to be useful for a majority of people.

Technology Connections: Long Lasting Bulbs

[–] anon6789 5 points 1 year ago

Definitely nothing like what people would picture an incandescent bulb to look like. It's cool as a curiosity, but not as a light source.

[–] rubythulhu@lemmy.blahaj.zone 9 points 1 year ago

Luckily for you, technology connection’s latest video goes into great detail as to why calling lightbulbs an example of planned obsolescence is definitely not accurate: https://youtu.be/zb7Bs98KmnY

[–] HobbitFoot@thelemmy.club 4 points 1 year ago

The bulbs work for longer, but they require more power to use.

[–] Dyf_Tfh@lemmy.sdf.org 2 points 1 year ago (2 children)

So far i have never replaced any LED bulbs, and the oldest ones i have are 15+ years old.

LED strips though, where a single dead led can bring down the whole strip, are absolutely a non sensical idea.

IME, LED whining gets me to replace them before they actually die. For old people who can't hear it, they should last longer.

[–] kozy138@lemm.ee 1 points 1 year ago

Well I've replaced over 10 in like 3 years. They can get much hotter than incandescent, which can damage the internal circuitry. Perhaps personal experience isn't the best gauge of reliability

[–] Chadus_Maximus@lemm.ee 1 points 1 year ago (2 children)

Damn. There are no LED's that can be put into enclosures, right? I suppose that's a worthwhile sacrifice to avoid idiots from sticking to incandescents.

[–] Uranium3006@kbin.social 1 points 1 year ago

I use all LEDs in my home and aside from the dollar store LEDs lasting less long in 2 bulb enclosures, all the ones in the ceiling boob lights are doing fine. I recently got better bulbs that as a nice bonus are a warm color temperature and I'll see how they do. the nicer LEDs have circuity that can reduce their output to reduce heat output if they detect they're being cooked from what I understand

[–] silence7@slrpnk.net 1 points 1 year ago (1 children)

There are LED bulbs rated for this. I've got several in fixtures like that.

[–] Chadus_Maximus@lemm.ee 1 points 1 year ago (1 children)

Where do I look to find them?

[–] silence7@slrpnk.net 1 points 1 year ago (1 children)
[–] Chadus_Maximus@lemm.ee 1 points 1 year ago* (last edited 1 year ago) (1 children)

Sadly I don't live in US of A so finding these bulbs is extremely difficult

I just want to go to a home Depot and get a few:(

[–] silence7@slrpnk.net 1 points 1 year ago* (last edited 1 year ago)

Take that website I linked — 1000bulbs.com — and look up bulbs that are actually available to you using it. You'll likely find that some are rated for enclosed fixtures.
