In any big enough company, risks, even if smalls, are prevented.
The same applies at national level, even stronger and strategic.

Here, concerning the climatic events, the same should apply. At least.

instead of believing this nonsense check the facts

venus atmosphere 96.5% carbon dioxide
earth atmosphere 0.0402% carbon dioxide

you do realise that its utterly impossible to even come near 0,1% without any major volcanic activity or some other apocalyptic scenario?

as a physicist i cant expect too many people to have the same understanding that i have, but one would expect people are not that stupid

Co2 is coming from the -soil-, and more heat coupled with chemical reactions (and simple physical effects of heat) generated more co2.

Are you really THAT ignorant ? Please stick on political discussion & far right statements, and never try this again, such a disgrace, but your excuses are accepted anyway, this kind of knowledge isnt accessible to everybody.

I guess i have to deal with it :)

yeah and that co2 is just piling up and nothing happens with it at all right?

dear lord, please grant this fellow some extra brain cells

Literally in the middle of the article it states how this is pretty much impossible to occur on our planet.

Earth, meanwhile, is protected from solar radiation by an atmosphere that is dramatically different from that of Venus.

"Venus' atmosphere is about 100 times thicker than Earth's atmosphere, and composed almost entirely of CO2 [carbon dioxide]," Robinson said. By contrast, Earth's atmosphere is mostly molecular nitrogen and oxygen, with less than 0.04 percent coming from carbon dioxide, Robinson told Live Science in an email. [Infographic: Earth's Atmosphere from Top to Bottom]

Without a thick carbon dioxide atmosphere and the extra dose of solar radiation from the sun, only willful malice is likely to cause a runaway greenhouse scenario, said Kevin Zahnle, a space scientist at NASA Ames Research Center, who has analyzed runaway greenhouse projections for the planet.

"There is no rational expectation of a runaway [greenhouse effect] in the facts as we know them," Zahnle told Live Science in an email.

For one, there were much warmer climates on Earth in the relatively recent past, such as during the Eocene epoch (between 56 million and 34 million years ago), and no signs of a runaway greenhouse effect, Zahnle said. At that time, CO2 levels were likely three times higher than they are now. Even imagining a future with cars, planes and air conditioning on full blast, no climate projections predict such high levels of CO2 in our atmosphere, he said.

"A runaway greenhouse effect is not in the cards," added Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado.

The actual atmosphere of Venus has nothing to do with its previous, the heat completely changed it.
So comparing the atmosphere composition of Venus today vs Earth todays is a non-sense. Now about this arcticle...

Thats funny here's NASA document too:

https://www.nasa.gov/feature/goddard/2016/nasa-climate-modeling-suggests-venus-may-have-been-habitable

Maybe this way your people could understand.

Btw venus temperature is far above the boil satus, it's nearly ~~ 870°F.


What is important to see here is the process of the change, that gone exponential, instead of linear

"However, Venus is closer to the sun than Earth and receives far more sunlight. As a result, the planet’s early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. With no water left on the surface, carbon dioxide built up in the atmosphere, leading to a so-called runaway greenhouse effect that created present conditions."

so, unless we somehow swap orbits with venus, how is this relevant to earth again?
