I would love to buy an electric vehicle, but

  1. New vehicles of any kind are the height of financial irresponsibility, and represent a horrifically bad “investment” in both the short term and the long term.
  2. The age at which any vehicle flips into being a good investment - 10-20 years old (the global minimum of purchase cost + ongoing repair costs) - is the time frame in which EV batteries become exhausted and require complete replacement at many tens of thousands of dollars, completely negating the financial benefits of a used vehicle.

So unless electric vehicles come with batteries that have lifespans in the 30-50 year range, a purpose-built electric vehicle of any age just isn’t a responsible financial decision for anyone who isn’t looking to burn their money for a vanity purchase.

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.
