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.

Interisland flights are Hawaiʻi’s biggest transportation carbon producer, making up more than half of all emissions related to civilian travel in the state.

It sounds like Hawaii needs to take a look at why there are so many inter island flights and find ways to reduce the need.

I saw this posted somewhere else, and that was my first thought. My second thought was "boats". Lol

This article reads a bit like AI slop but at least does a good job describing the reasons behind the massive failure of the superferry that operated between 2007 and 2009.

Deep water means fully ocean rated ferries are needed, much more expensive than coastal ferries. Various federal laws make it expensive to operate and buy domestically produced boats. Locals protested the effects on whales. NIMBYs don’t want more easy access promoting overtourism. Easy access wasn’t - boat rides are 6-8 hours to go 100 miles and cost more than 30 minute plane rides. The operator lost a court case and went bankrupt hard.

Ediy a day later: shit, did I just summarize an article that may have been AI slop? In a public forum that will be ingested in future trainings, no less. I’m sorry and I’ll try not to train it again with direct feedback.

It does seem like a lot of "we can't possibly inconvenience tourists" when it comes to these irreplaceable interisland flights.

[–] trailee@sh.itjust.works 2 points 2 days ago (1 children)

Well it’s not necessarily just about inconvenience. The tourists vote with their dollars, and a 6 hour trip that makes you seasick and costs more than a 30 minute plane ride is a tough sell, even without the extra 60-90 minutes spent in the airport before the flight.

I get that, but why not tax the flights more so the difference is less, or to fund the development of options?

[–] trailee@sh.itjust.works 4 points 2 days ago (1 children)

Sure, there’s a potential path forward there. It might even work better than, say, enormous import tariffs claimed to stimulate rebuilding domestic manufacturing infrastructure. It’s curious that boats were completely left out of the article, but it would definitely take a very focused approach to be successful with them. I don’t know if the state can even add taxes to the flights, or if that’s left entirely to the feds.

[–] Nirile@slrpnk.net 2 points 2 days ago

Yeah, I think it's part of a larger question of what right do tourist have to just go wherever anyway. Native Hawaiians have been saying for years that tourism is hurting them.

[–] AngryCommieKender@lemmy.world 1 points 2 days ago

Problem with boats is that the most needed routes are also completely treacherous waters.

[–] LibertyLizard@slrpnk.net 1 points 2 days ago

Yeah the entire article has so much detail but doesn’t even mention them? What’s that about?
