  • Compare the top 10% of that cohort against the rest

    Top 10% emit 22 tons of CO2 per year per person [1].

    8 billion * (10% * 22 tons - 1% * 50 tons) = 14 billion tons of CO2 per year, excluding the top 1%.

    Share of total emissions:

    Upper middle class (top 10% excluding top 1%): 39%

    Lower middle class (top 50% excluding top 10%): 38%

    when you create a graph like that without putting values on the axis it’s inherently misleading

    No, it’s a common way to present data in a popular scientific context.

    the issue here is disproportionate impact from the minority.

    No, as the graph shows, the issue is the disproportionate impact from the richest half of the population. Even without the top 1%, the remaining 50-99% percentiles emit far too much. Even without the top 10%, the 50-90% percentiles still emit far too much.

    The downvotes on this post just goes to show that lemmy is overrun by a new generation of climate change deniers, denying not the phenomenon as such, but their own culpability in it.

    But they’ll get what’s coming to them.










  • Fair.

    The point was not to imply that shipping is not a large source of CO2, but:

    1. More than once, I have seen it stated that a small number of cargo ships dwarfs the world’s car fleet in terms of CO2 emission. This is wrong, and originates with abovementioned conflating of sulphur and carbon.
    2. At 3.9% of all GHG emissions, it is hardly correct to refer to shipping as one of the “biggest CO2 polluters”.
    3. It’s not low hanging fruit. Moving cargo by sea is really very efficient, and we’re not going to reduce that carbon source by switching to other means of transport. The only way to reduce it is to move less stuff.


  • The biggest CO2 polluters are […] cargo ships.

    No, this is a misunderstanding. Cargo ships are a major source of sulphur pollution, not carbon. Cargo ships use the cheapest fuel they can. Cheap fuel is rich in sulphur. They can do this because there are no emission regulations on the open sea. A commonly cited figure is that a single cargo ship release more sulphur than all the cars in North America.

    This figure is then misinterpreted by people who failed basic chemistry to mean that cargo ships are a major contributor to greenhouse gas emissions. In reality, the opposite is true; cargo ships are one of the most efficient ways to move stuff over large distances. Only electric trains are better, and only if the source of the electricity is not fossil.


  • Varför dömde HD så dåligt i frågan?

    HD har inte dömt i frågan. Skolskjutsen nekades med hänvisning till en dom i HFD (inte HD) tidigare i år, men ingen rättstlig instans har tagit ställning i detta specifika ärende. Beslutet är överklagat till förvaltningsrätten.

    Det framgår inte vilken dom som hänvisas. Det återstår att se om förvaltningsrätten håller med Laholms kommun i att domen ska tolkas på detta sätt.

    Varför tillåts vägar som är så här pass osäkra att existera?

    Vägen är bara osäker om folk envisas med att gå och cykla där. Om föräldrarna helt enkelt skjutsar barnen med bil är problemet löst en gång för alla.


  • Because the point of the comparison is to determine if the infrastructure investment was cost effective. What would traffic look like today if the money had instead been used to build public transport, bike lanes, and walkable streets? If the alternative investment had improved traffic even more, building the highway was the wrong thing to do.


  • It’s probably gone down, actually, at least in per capita terms. Boston’s population is a lot bigger than it used to be, so that has to be taken into account.

    The comparison is between today and ‘today but without the highway’, not between today and before the highway was built. If the population increase is greater with the highway there, that’s still part of the induced demand.

    Boston is far from car dependent; it’s probably one of the worst cities in America for drivers, and best for cyclists and pedestrians.

    A city being “bad for drivers” is not a great indicator of it not being car dependant. Cities in the Netherlands are probably the most walkable and bikable on the planet, and also great to drive in because there are hardly any cars.
