[Coral-List] ICRS2020 and remote meetings

[frahome at yahoo.com]

 Latest posts tried to proof that 1) planes are more efficient than cars (is this really relevant to the discussion where nobody was suggesting to replace planes with cars?)2) planes are only 2% of the world emissions ( predicted to grow if demand doesn't change in a situation where the world is called instead to cut emission by 50% by 2030 and 100% by 2050). Based on the above data/science you would conclude that it is ok for scientists to emit 10 t or more of CO2 emissions per capita per year when the per capita budget to avoid climate breakdown is 0.6 t? Concluding otherwise would be based on passion and emotions? Francesca

 Absolutely Osmar, and here another article on the topic that came out today:

https://ensia.com/voices/flight-shaming-flying-travel-carbon-co2-emissions-flyless-aviation-cars-trains/

A few juicy bits from the article:

1. "Passenger aircraft emissions are in the same range as nearly all road
transport emissions".

2. "An individual’s decision to take or not take public transit does not
affect the emissions of that trip. But a decision to drive does. So, if you
choose to drive because it is more climate friendly than flying short-haul,
you are adding an extra car on the road while the plane would have flown
anyway."

3. "While we want to reduce the climate impacts of aviation, we need to
remember that flying produces only 2% of total emissions today. Even if
everyone were to stop flying, the total climate mitigation impact would be
negligible."

I wish people (especially scientists) used less passion and more
data/science in their decision making process.

Cheers,

Luiz
