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.

The corals are casualties of surging global temperatures which have smashed historical records in the past year — caused mainly by fossil fuels driving up carbon emissions and accelerated by the El Niño weather pattern, which heats ocean temperatures in this part of the world.

It’s so depressing reading headlines like this and having no power to affect the outcome.

Does anyone have any IT or electrical questions I can help with?

Firms working on decarbonization need IT, and if you're licensed as an electrician, there's a lot of work replacing heating systems and hot water heaters with heat pumps to be done

I know all that. I’m leading the initiative to convert all the sites my company operates to 100% solar power. Before that I led the initiative to convert to all LED lighting. I’m doing what I can, it just feels like I’m shooting a squirt gun at the sun when I read stuff like this.

Two questions. I'm running a c# kestrel based Web API behind an nginx reverse proxy and alongside a reactive frontend. Why is CORS such a pain in my membrane.

Secondly. Is there a good way to figure out what all is on which breaker in my new breaker panel that has zero labeling because the old one was just straight up wrong? I really don't want to have to flip one off, walk through house, see what's off, go back, flip on, flip next off, etc.

Question one: way over my pay grade. I’m closer to a CCNA than a software developer.

Question two: flipping breakers on and off is really the best way to figure out how your house is wired. It is MUCH easier if you have someone who can help you. Lights will be easy and obvious. Things like wall receps will take some time. Especially if you have an older house where past owners have made modifications. There are circuit tracers for this but they don’t work that well. You’re better off using a voltage tester or outlet tester that will beep when it has power. Any breaker that is a double or two pole breaker will have a specific purpose. If it’s 40 amps there’s a good chance it’s an electric oven or drier, if it’s 60 amps it almost certainly your HVAC.

Well, the CORS thing is just your browser protecting you from an XSS attack. So the API just needs to advertise the origins that are permitted. Like writing "stolen from xyz" on your tools.

The tricky part with electrical will be which things get missed. Like finding out the microwave has its own circuit that's shared with the bathroom fan or something. What you could do is buy 50 IoT devices and record which ones connect to your wifi after you start flipping breakers. You might be able to do some clever bracket to determine which outlets are on which circuit, but hardwired appliances will be more manual.

The ocean will starve to death. People will too. Earth is rapidly becoming a wasteland. Often seems like too few seem to care and that's probably just going to become more true as time goes on. It's so deeply horrible.

It would be interesting to see if a CRISPR type technology could make coral reefs more resilient to climate change.

The difficulty is likely deciding which genes to turn on and which ones to turn off.

What scientists are doing instead is taking corals that are demonstrating heat-resistance, propagating them in labs, and trying to introduce them back into the wild; it's a kind of directed evolution. The difficulty is lack of funding and keeping up with climate change.
