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.

Dutch people cycle an average of 2.6 kilometres each per day. If this pattern was replicated worldwide, the study suggests, annual global carbon emissions would drop by 686 million tonnes.

This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.

I got 54kms to get to work every day and no place to park that's safe between.

I would be happy as a Clam to save my morning run and go to my car but it's not feasible unfortunately.

Maybe stop putting the buck on people trying to make a living and give it to politicians who fly privately or massive shipping companies.

Nobody's asking you to cycle for 110 km per day, and the Dutch don't fo that either. It's about building cities that are bicycle-friendly, and where people can live in reasonable proximity to their job and all services.

If you're in the US or Canada the problem is likely zoning and suburbia.

The problem is look his densely populated European cities are. Here we have sprawl and more sprawl.

So given the cities are have now, what can we do? Can't simply build a new one or tear the old one down.

Stop voting for politicians who want to get rid of existing bike lanes (Doug Ford - Ontario, Canada), stop voting for politicians who oppose high density residential zones (gestures at most of the developed world), and vote for politicians who have the best public transportation plans. Get involved with city politics a la the annoying people in parks and rec. It works. Donate to and get involved with your local progressive organizations (shout out to https://www.progresstoronto.ca/).

You did that already once, when decided to move to car-centrism. No reason not to do it again

[–] mirshafie@europe.pub 3 points 2 days ago

Just narrowing the space for cars and adding continuous walking paths plus protected bike lanes will get you pretty far. The goal isn't that every single person should travel by foot or car every time, it's to make it more common to use those travel modes in general.

And build passenger trains.

Ebike are expensive. I know people how bought small used cars for the price of an ebike.

I once bought a used bike for 12 € another time for 5 €. Yes, it was a long time ago and we got inflation since bit ever since bikes become trendy, they got overly complicated and overly pricy. That doesn't help people cure their carbrain syndrome.
