Climate - truthful information about climate, related activism and politics.

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.

This electric school bus has a range of up to 300 miles (arstechnica.com)

Ideally, rezoning and infrastructure changes would reduce the need for school buses. We don't have the time though, so this is a win. Hopefully production can ramp up and governments can create incentives for schools to buy these instead of dead dino powered buses.

School busses are one of the perfect fits for electric engines:

Set schedule with down time to charge Specific route with known distances. Heavy and must drive up hills: which benefit from amazing torque generated by Electric engines. Large internal space for battery storage

Just pray Muskrat doesn’t somehow win the bid. We’ll never see them

Elon would do something ridiculous like buy Lyft for 10 billion too much and require drivers to use Teslas. He would then get a cost+percentage transportation contract. He then gold plates the interior components after a few years so the cost is higher, therefore the percentage is bigger.

And as long as it can cover the longest route on one charge it wouldn't need to cover that same distance every trip. You could pick the buses route based on battery % and have them alternate.

You’re forgetting the most important feature, usb charging ports for every seat

I can already imagine someone shoving gum into them :(

Subscription based of course.

Meh, outlets are superior than USB ports. USB wears out too quickly with rough use and, with USB-A, the charging cannot exceed 15W.

I saw a video of the latest Tesla model 3 2024 and it has one USB charging port inside the center console lol.

There are also 2 in the back, below the screen/hvac, and there is a dual wireless charger up front, so that’s probably enough isn’t it?

[–] Polar@lemmy.ca 1 points 1 year ago

Wireless charging isn't the same.
