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.

I want solar but I don't want it on my newish roof with a 50 year waranty. I get why roof installs are popular but why does it seem to be the only solution for consumers that is offered. They can look at my house from maps and see of got a sizable empty plot of land next to my house that could also be used.

And not to mention how expensive it is to get a new roof installed with solar panels on it. They charge a lot of money to remove and put back the panels.

It should be illegal to have a roof without solar.

It should be illegal to not architect a home to maximize solar.

California has a terrible law that promotes "builder grade" solar of the minimum regulatory size, and then makes adding proper solar more expensive than if they didn't fuck up the house intentionally.

Eh I got the land for it why couldn't I use it? Solar on the roof means you have to go on the roof to fix or troubleshoot. You are adding holes to your roof, unless if you get the tesla solar roof in the first place which you can't trust anything made by them so you are better off keeping them separate.

The only pro I have seen with it being on the roof, which is probably a good one if true, since it is attached to your house, your home insurance would have to cover damages from bad storms / freaks of nature.

Edit: Also beyond the obvious not needing additional land for it.

Because you should be planting trees on that land.

one solar panel removes more Co2 than 10 trees. (by displacing FF energy)

[–] jagged_circle@feddit.nl 1 points 12 hours ago

We need both

Depending on the location, no, not really.
