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.

Legends πŸ‘‘

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 2 years 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 3 points 2 years 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.

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

[–] MonkderZweite@feddit.ch 3 points 2 years ago (1 children)

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

[–] kilgore_trout@feddit.it 2 points 2 years ago

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

[–] lunachocken@lemm.ee 3 points 2 years ago

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

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

[–] mondoman712@lemmy.ml 5 points 2 years 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?

[–] Toldry@lemmy.world 5 points 2 years 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 2 years 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 2 years ago* (last edited 2 years 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 2 years 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 2 years ago (4 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.

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.

[–] Sibbo@sopuli.xyz 5 points 2 years ago

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

[–] Tristaniopsis@aussie.zone 5 points 2 years ago (1 children)
[–] jojowakaki@lemmy.world 3 points 2 years ago

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

Are there train stations at the airports for connections?

[–] charlytune@mander.xyz 16 points 2 years 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 2 years 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 2 years ago* (last edited 2 years ago)

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