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.

280 million e-bikes are slashing oil demand far more than electric cars. E-bikes and scooters displace 4x as much demand for oil as all of the EVs in the world. (arstechnica.com)

That's got a very real impact! But companies being wasteful isn't a reason to throw the baby out with the bathwater. There are still a lot of micromobility options that are replacing car trips and that can only be seen as a good thing. And it's not like you won't find many more tons of plastic and steel in automobile junkyards. But, yes, I agree we should avoid a situation where we flood the market and end up with bikes getting discarded wastefully.
