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 work in the industry. as I see it this will be used along the major harbours along Chinese coast. if we see them elsewhere it could be along the east/west coast of the US or Mediterranean in Europe. but it is limited. and not global trade. more like regional distribution. also as a Dane. we have two electrical ferries connecting to other countries. this is super interesting as they are running often small routes and thereby reduces local air pollution a bit similar.

That does make more sense. I know we have a hybrid ferry in Portsmouth but I think it is more designed to reduce emissions right next to the city and then charge up on the main engines while crossing. Not that it ever gets more than a few miles from land but I suppose its slightly better.

well you made the 10 hour claim calculation :) 10 hours ain’t long. it takes about 3 weeks from Asia to Europe shortest route. 24/7. so a 10 hour journey limits that usage ;) I seem to remember from Bremer Hafen to Hamburg it easily can take 6-10 hours. due to waiting and traffic. so it will be short harbor routes for sure ;)

10h is based on the article for the energy stored and the energy used by the motors. But it would be if the motors are running at 100%

I'd love for everyone to go full electric. The US is literally doing the opposite though, so I wouldn't expect to see these in American waters for a long time.
