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.

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.

Many tens of thousands for a new battery? Maybe for a Tesla.

Leaf batteries are cheap AF at about $4k, and the rest are all less than $15k

Even then, those batteries last quite a while and tend to have decent waranties attached to them.

Your comment is pretty offbase IMO

To a lot of people $4k isn’t cheap when a petrol powered car can be bought for <$1000

What planet u live on where u find 1000 cars????

Dude tires cost 1000

Minimum for a decent car is 5k and average is closer to 10k in 2024

Bro your tires are expensive. I just put 2 on literally last week for $300 including labor.
