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.

who never travels more than 5km from their home without taking public transport.

So 90% of all humans (excluding 'murica, I guess)

it’s only relevant if you’re a young single person

Literal bullshit. Are your legs made of styrofoam? If not, you can handle a little cycling.

Actually, in February I spent 22 hours on my mountain bike - I know you don't care snd perhaps not a big deal but it's a recent achievement in quite proud of.

Regardless, my comments are not about fitness. Young single people tend to have less commitments.

My partner and I have newborn twins. The only transport options are pram and car. We do have a bike trailer for them but it's not really safe until they're 1.

The same situation applies if you're caring for an elderly parent. Which I am.

The way you assume it's about fitness is kind of a "case in point" to be honest - you're incapable of considering that others have different transport needs.

Why the hell are you taking newborns or elderly people in long commutes (and not using a train)?

I live in regional Australia. There are no passenger trains within about 5 hours drive.

The city I live in has about 50,000 people. I'm not in the middle of nowhere.

My parents do live in the middle of nowhere though, about an 150km from the nearest grocery store.

My circumstances aren't that unusual really.
