Cool, now do the same chart but instead of energy use time.

Time us is so heavily dependent on location you cant standardize the data effectively

The solution has always been better cities and better mass transit. EVs are a distraction.

Yeah but what about if a person is a massive hambeast? Ain’t no cycles going nowhere under that strain.

Or what if they are a massive douchenozzle chud fuckwit?!? It would emasculate them to not have the largest most unnecessary truck possible?!?

Keep in mind that although an electric bike might use more energy input than a regular road bike, it uses a much cleaner type of fuel. Even the most dirty coal power plant in the world has a significantly lower CO2 output per watt hour than the food you are eating to power a bicycle. Even if you are vegan

Wrong.

Coal power has a CO2 intensity of ~1 g / Wh (source: IEA)

A plant based diet has a CO2 intensity of ~1 g / Wh (source: ourworldindata)

Production CO2 intensity of a bicycle is also lower than an e-bike.

Pedaling under your own power also has health benefits, which the e-bike rider would need to do additional exercise to achieve, thus increasing their total CO2 intensity further.

In short, sit the fuck down and shut the fuck up about shit you clearly don't understand.

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.
