I don't think there is a lot of methane coming out of a volcano but yes a volcano can "pollute" in a few hours what man takes decades to do... but don't let that become an argument to minimize the human impact (I see it coming like a house in the coming days).

A volcano has no consciousness ... and the 2 effects will be CUMULATIVE ...

This morning no big change in southern Belgium: there are clouds as usual : Mrgreen:

So where is the ecological "benefit"? How many trucks for a plane?


The truck, if it is not blocked and turns "for nothing" has a performance much higher than the best planes.

Example on energy consumption / CO2.

The best planes are below 3 L / 100km. Passenger if the average passenger is 120 km (with suitcases) then this makes a specific consumption of the order of 3 / 0.12 = 25 L / 100km.

The consumption of a truck is between 30 and 50 L / 100km ... for 30 tonnes displaced!

The CS is therefore of the order of 50/30 = 1.6 L / 1000km. Useful ton take 2 in an unfavorable case.

A truck is therefore 10 to 15 times better than the best planes in consumption per payload moved.
A car on the other hand is of the same order of magnitude as airplanes (strongly depends on the average load of the car).

What is to be seen now is what will happen, whether it lasts a long time or not ... :?

In any case, I will not be made to believe that there is no acceleration of seismic activities : Cheesy:

For the rest we will do well, but ... wait & see!

We are in an "active" period, that's for sure, but earthquakes often happen in series ...

kk1 would have statistics on hand because there have "always" been large earthquakes, except that we talked less ... less publicized world ...

Hopefully it will not be like in 1783 which led to the French Revolution !!! Apocalypse'
http://news.bbc.co.uk/2/hi/uk_news/magazine/8624791.stm
The noxious fog traveled down through Norway, Germany, France and across to Britain, causing panic when farm laborers began dropping like flies. People at this time had no idea where the fog had come from or that sulfur dioxide was mixing with water vapor in the lungs to choke victims. Research into parish records has led to estimates of more than 20,000 deaths in Britain alone during the summer of 1783.

Not to breathe !!!
But nowhere suffered more than Iceland. It was not the eruption itself that proved deadly but the environmental consequences, says Gunnar Gudmundsson, a geophysicist at the Icelandic Meteorological Office.

"People died not because of the eruption, but because of starvation," he says. "The farm animals died, the crops died - it affected the whole country."

Toxic gases poisoned the plants and vegetation, which in turn killed the livestock. Eight of every ten sheep are thought to have died, while half of all the cattle and horses perished. The extreme winters that followed - caused by the sulfur gases - ensured that a fifth of the country's population died, historians estimate.

Past misfortune can happen again !!

The world is no longer that of the 18th century and to achieve the same level of famine would require a natural disaster much more severe than that of the time!

Reasons? Globalization and overproduction / food waste today ...

@ Christophe,
thank you for the clarification. The problem therefore lies elsewhere.
1) motorway traffic jams by "overcrowding" of trucks (but as it is the holidays, all is well ... for now)
2) technical unemployment in the factories because of the tense flow if the ban on flying were to continue.
Wait and see, the future will teach us.

Yes of course. It is the "unreasonable" that poses the problem.
And not only in agriculture.
No petroleum, no prosthesis (hips, knees ...) or painkillers.
But from there to believe that a blue pill will give happiness, there is a step ...

The industrial and economic development of the XXieme century (at least among the "rich people) owes a lot to oil ... what am I saying, it owes almost everything to it!

To come back to the subject: today there is a big clear sky and I really have the impression that the sun "beats less" just on the skin it feels ... and the horizon is grayer than blue!

So I have the impression that we do have a reduction in radiation, but hey it's still quite subjective ... would need a pyranometer : Cheesy:

The airports are still blocked until 20 p.m. tonight and given the money involved, there are really risks ...

In short it may be to be taken more seriously than one might think ...

I live in a small valley

when i go to town i overlook everything

I can tell you that when I am above and that I look at the horizon I see the earth, a thick brown layer and finally the sky

short a little more gray in brown does not change much 8)

4 to 5% is a good number

given that oil is the result of the gaseous air of the earth there are many other gases much more dangerous than CO2
(not counting deadly calamines)

let's not forget that in the gas air nothing lived or survived

the contemporary is to lock up in the garage and to light the car engine
there's no point asking him if he's suicidal
he is not suicidal but in the wind
