...that's the short-sighted "business perspective".

In reality nobody really "needs" those short-haul flights and they need to be outlawed, just as some domestic ones are now.

...and compared to this country's total population, I pay very little taxes, so I might as well stop paying them...

But I agree with you insofar as CDG also has lots of ridiculous international connections, like to Frankfurt, Brussels and Amsterdam.

So many people are sharing this (impressive) video saying that 3 freeriders died there 🤬
LIE!
The avalanche shown here was (intentionally) triggered yesterday (17/02) at Fauteuil des Allemands.

DIFFERENT from the one on 15/02 where 3 died in Canale del Vesses, on the other side of Val Veny! 🤡👇

For his next trick, Trump's going to spend the rest of the day deleting greenhouse gas absorption bands with a Sharpie! Maybe he can open the atmospheric window wide enough to cool the planet -- thank you for your attention to this matter, Mr. President!

Diagram showing absorption spectra of the most important greenhouse gases (water vapour, CO2, methane, etc.) with % absorption on the y-axis, and wavelength on the x-axis (logarithmic).
Someone has gone through and drawn heavy black X's over all the peaks on the longwave part of the spectrum (to the right of the visible wavelengths).
Above that is the overall atmospheric absorption peak pattern, and above that is the graph for energy intensity of emissions and the different wavelengths, shown for solar radiation at 5525 K (orange) and radiation emitted by the Earth to space at 210-310 K (blue). The peaks are widely separated.

Tipping point threshold temperature estimates are shown with black dots; floating bars indicate lower and upper estimates. Note that the estimated tipping threshold of 1.2°C for low-latitude coral reefs has likely already been crossed.3 The dashed purple vertical line indicates 1.5°C above pre-industrial levels; a sustained global average temperature at this level is likely in the near future.2 Tipping point thresholds are adapted from Armstrong McKay et al.13 with updates from Lenton et al.3 Tipping impacts and timescales vary greatly. In some cases, effects on global temperatures may be uncertain or negligible (gray bars). Note that overlap can occur among feedbacks and/or tipping points, so their effects are not necessarily independent. See supplemental methods for further details, including data sources.

Let me tell you that I spend way less than your $320 for fuel in my 20 yrs old Volkswagen.

How I do that? By taking buses, trains and by walking and cycling.

Let me add that a lot of my work is in Marseille, Paris & other European cities (I live in none of them).

The car obsession is hilarious.
