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 am well aware of the problems with car dependent design, that isn't what this is about.

I was driving in my car mandatory suburb and was delayed by a good 10 minutes due to a pair of very poorly timed lights. The main thoroughfare had a left turn lane split off that was backed up onto the main road. The turn light would literally turn green for about 5 seconds. A bit further down the road, a light controls traffic to a neighborhood of SFH with very few cars coming or going. The light on the main road would turn red for literally no cars longer than the other light stayed green with so many cars it caused a backup.

Simply adjusting these traffic lights would save loads of time, fuel, and EMISSIONS. It got me wondering what other things like adjusting those lights could be done that even the thirstiest petroholic can't object to?

My example is a drop in the bucket to the GHG problem, but enough drops will fill the bucket. I will be contacting my city about it. I don't doubt they will at least attempt to fix it because traffic is a common complaint, so a simple fix is an easy win for them.

roundabout. I like roundabout. My city council love traffic light so they put traffic light on every junction which create the problem you mentioned. It can be solved by roundabout. It has its downside but who care, i like roundabout.

Came here to comment this and was not disappointed. They're safer as it's impossible to have a head-on collision and keeps traffic flowing better.

The main reason they're not as common in North America is because they got it wrong when they started using them in the USA by making those coming into it have right of way and they never caught on.

This is a really good podcast episode on the topic: https://www.iheart.com/podcast/105-stuff-you-should-know-26940277/episode/roundabouts-the-problem-is-you-29861275/
