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.

Lol an ebike huh? You're freaking hilarious.

Well you didn't specify additional cargo or other reasons for limitation.

For example if the issue is travel time: electric motorcycle if the issue is cargo: electric bike with travel trailer if both travel time and cargo: gas to electric conversions are affordable (with the batteries being the highest cost [and the determining factor for range])

basically the less mass needing to be accelerated, the less energy required. The lower the acceleration acceptable, the less energy required.

Treat it as an engineering problem to solve or improve upon.

I'll stick to what I have thanks lol. I'm actually saving up for a motorcycle to go to work. Not an electric motorcycle though as they are still very expensive and have a lower range than I need. Sometimes looking at issues from a real world perspective can help. I work with engineers and unfortunately they cause issues at work not thinking in real world terms.
