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.

It is reversing a ban on oil and gas drilling, and is proposing a “fast-track” for big projects, including mines, that bypasses environmental checks. It has cut climate programs and jobs, scrapped electric vehicle subsidies, abandoned plans for one of the world’s largest marine sanctuaries and set aside a world-leading cow “burp” tax as it questions the science on methane, a potent greenhouse gas.

Sydney has 6 million people compared to Auckland 1.2., Melbourne 5 with similar land area. If you look at % then yes, look at people per sqkm we are no where close.

So you don't need as many buses to achieve the same coverage. Public transport infrastructure costs are not fixed for a certain land area, they are also proportional to potential ridership.

Backwards- if you want to cover areas your network needs to be the size to cover it. Its much more comparatively expensive when you have 3 people riding each route rather than 18.

You're correct on main lines, however you can also run larger busses.
