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.

Incredibly based.

It helps that Spain has world-class trains and are continuously investing in expanding the network.

I'm so jealous. I wish the complete shitstain right-wingers that cancelled train investment in my country were fired. (out of a cannon into the sun)

As Spaniard I wouldn't go that far.. but yeah they are good. But not all of them πŸ˜… specially the shorter routes. Apart from some maintenance issues, It doesn't help that from time to time a line is down because they have stolen copper wires...

[–] GissaMittJobb@lemmy.ml 9 points 8 months ago (2 children)

One tragic fact of life is that it doesn't really take that much to become world-class as far as trains go. The HSR network alone basically places you on the podium.

[–] wildcherry@slrpnk.net 2 points 8 months ago

To be fair (and Im from a family of train workers, did my master thesis there), there is a lot of mismanagement and politics, lack of investment and stuff, which decrease the quality of train services. But there's also part of the problems who are inherent to the fact of moving steel boxes safely on thousands of km, without endangering the workers either.

Depends on the age of your tracks, if you have old Victorian bridges etc or aging signal systems it can be very hard indeed.

(London btw)

[–] lud@lemm.ee 6 points 8 months ago* (last edited 8 months ago) (4 children)

People steal the copper wires everywhere.

I know someone that works in the rail industry with building and maintenance.

It's apparently very important to electrify the wire as soon as you are done with whatever you were doing. Otherwise someone will know that it's not electrified and they will steal it. And the company/state will lose quite a lot of money in raw materials (the overhead wires are expensive as fuck), delays and further work.

Edit: This isn't in some third world country or anything either. This is in a rich first world country that's in the top 10 in terms of HDI and at least top 20 of pretty much every other positive index.

I was once running to the station in sevilla to get my train. I arrived 40 minutes late. The train departed right after I boarded.

Much love to the renfe, they waited for me :3

[–] lunachocken@lemm.ee 3 points 8 months ago

Why bother wasting the resources to send em to space, when a bullet suffices.

[–] MonkderZweite@feddit.ch 3 points 8 months ago (1 children)

I read about world-class and then 40 minutes late...

[–] kilgore_trout@feddit.it 2 points 8 months ago

Delay is most of the time due to congestion. Expanding the network is the way to reduce that.

The move to trains in Europe seems great! But still it costs me ~Β£300 short notice, ~Β£100 otherwise per person to get from London to Paris by train so for any trips it'll still need to be planes unfortunately. I dream of a day I can make an affordable night time trip to the Mediterranean on a train

[–] huginn@feddit.it 35 points 8 months ago (2 children)

The UK has an atrocious train system in terms of cost.

Point fingers where they belong: your own government.

[–] lntl@lemmy.ml 11 points 8 months ago (2 children)

amazing that building, maintaining, and fueling a fleet of airplanes is more cost effective than a few engines, coaches, and track.

[–] InternetCitizen2@lemmy.world 15 points 8 months ago (1 children)

That's the innovation of privatization.

[–] wildcherry@slrpnk.net 4 points 8 months ago (4 children)

Yea I got a fine because I took an Avanti North-west instead of an Avanti Wales train, on the same route -_- like wtf, if they are not the same company maybe they should not share the same name?

thanks a lot margaret

No taxes on fuel

Trains use infrastructures and not the air

it's just 2 examples. Complain at your government if you want things to change.

[–] TBi@lemmy.world 9 points 8 months ago

You are correct but we should also point blame at the people who vote them into power!

[–] mondoman712@lemmy.ml 22 points 8 months ago (1 children)

The pricing and general operations on the Eurostar are pretty crap, which also annoys me to no end since I also use it semi frequently. Thankfully from what I've heard the high speed trains in Spain don't suffer from the same issues.

[–] elgordio@kbin.social 5 points 8 months ago (3 children)

Hopefully some competition will improve things. If this gets off the ground it can only be good for prices and service. https://www.euronews.com/travel/2023/10/12/evolyn-the-high-speed-rail-startup-with-mystery-investors-coming-for-eurostars-crown

[–] gaael@lemmy.world 11 points 8 months ago

"Competition will improve things" yeah sure.

Mass rail transportation as a public utility at an affordable price for everyone is never going to be a profitable operation. Competition in such a setting won't improve anything.
They'll just invest to run things at a loss while maintaining the same quality for a few years, get their share of the market and run the historical company in the ground, then increase prices and lower quality.

[–] Aceticon@lemmy.world 5 points 8 months ago (3 children)

If the is one thing that the last couple of decades of privatised trains in the UK have shown, is that there is no possibility for real competition in trains, which should've been obvious from the start as you can't just have tons of companies lay train track at will to compete with uncompetitive established train operators.

The competition to trains are buses, cars and to a lesser extent planes, and some of those are only competitive against trains because their Negative Externalities (i.e. Polution) aren't reflected in the ticket price.

This would be great, but won't happen as quickly as they say, and even if a competitor does get going, the lack of capacity at St Pancras is a major blocker to reducing the ticket price.

[–] jojowakaki@lemmy.world 9 points 8 months ago (1 children)

Correct me if I'm wrong, but this only applies public flights not private flights.

[–] mondoman712@lemmy.ml 5 points 8 months ago (1 children)

IIRC that's the case in France, but per the article

It isn’t yet known how many flights will actually be impacted by restrictions.

How about closing airports as well so private jets have no places to land and the overlords can take the fucking train like the rest of us?

[–] Tristaniopsis@aussie.zone 6 points 8 months ago (1 children)
[–] jojowakaki@lemmy.world 3 points 8 months ago

Not applied to private flights from what I grasped. Taylor swift can rest easy.

Also for connecting flights, or only if the whole trip is a single short haul flight?

[–] Toldry@lemmy.world 5 points 8 months ago (5 children)

PP member Guillermo Mariscal explained that he believes the initiative is β€œineffective” because it would only result in a 0.06 per cent reduction in emissions according to data from the College of Aircraft Engineers (COIAE).

Really? Just 0.06%? How can it be so low?

[–] elbarto777@lemmy.world 11 points 8 months ago

It depends on what the 100% represents. Does it represent the emissions of just Spain or the whole world? If the latter, then it makes sense.

But every bit counts, so this is a welcomed change - to an extent. Family and work emergencies will have to wait longer with this, for example.

[–] deikoepfiges_dreirad@lemmy.zip 8 points 8 months ago* (last edited 8 months ago)

It says in the article, the number of flights this would affect might be very small. They originally wanted to ban flights with a train alternative under 4 hours, but that didn't get through.

[–] Blackmist@feddit.uk 5 points 8 months ago

Because he's from the college of aircraft engineers, who may have a vested interest in flight, and is therefore paid to make that number look as small as possible.

[–] kubica@kbin.social 3 points 8 months ago (1 children)

The article talks about a plan, which depending on what it includes would vary. In the article one optimistic prediction says 10% the other more pessimistic says 0.06%. Until more decisions are made the real number will be unknown.

[–] bier@feddit.nl 2 points 8 months ago (3 children)

Also because aviation is actually not a big part of the CO2 emissions

https://ourworldindata.org/emissions-by-sector

We should still try to fly less, but there are other sectors that can make a much bigger impact.

[–] golli@lemm.ee 3 points 8 months ago* (last edited 8 months ago)

It might be a low number, but then again this also seems like a initiative that will affect an even smaller number of people and is targeting something where a completely valid alternative exists, that has lower emissions.

It might not be the end it all solution, but there won't be one of those. So measuring it by that standard seems pointless to me.

I'd rather look at things like: Is there an alternative (and if so, what compromises does it make), what are the relative gains, and how easy is it to implement? And banning short distance flights seems to check those marks in my book.

[–] Yeller_king@reddthat.com 4 points 8 months ago (3 children)

Are there train stations at the airports for connections?

[–] charlytune@mander.xyz 17 points 8 months ago

I think every airport I've been to in Spain is connected to the rail network. Connection to rail and bus is pretty standard, in Western Europe at least.

[–] Michal@programming.dev 7 points 8 months ago

Airports are notoriously badly connected to final destinations, while trains usually take you to the city center and other public transport.

[–] kilgore_trout@feddit.it 5 points 8 months ago* (last edited 8 months ago)

All the main airports are reached by train. Spain has relatively cheap high-speed railway network.
