so where are the ruins?

are you fucking retarded?

Instant resort to insult reveals your lack of answer

There is precisely zero chance of us achieving Venus-like conditions via fossil fuel combustion. All of the fossil fuels in the entire planet was, at one time, in our atmosphere.

If we were to burn all of it, then proceed to burn all life on Earth, then we still wouldn't reach Cambrian-level CO2 concentrations because a lot of carbon is stored in non-combustable rocks.
If a Venusian catastrophe is even remotely possible on Earth, it would have to be volcanic in origin. And we're talking about a volcanic event of apocalyptic proportions the likes of which the Earth has never seen.

*note: I'm not disputing the effects of climate change nor its anthrogenicity. But the reality of climate change is a lot more "massive pain in the ass that we'd rather avoid" than "end of the fucking world."

>>16958660
The reason Venus has all that carbon in its atmosphere is in fact because it couldn't sequester it in rock like Earth did. Early on it got hot enough to boil the oceans off (thanks to the Sun), disrupting the inorganic carbon cycle and creating the initial strong greenhouse, and then there was nothing to trap all the volcanic emissions so it just kept getting more hellish while even the water vapor (its hydrogen mainly) was lost.
In theory the same could happen to Earth IF we got to that point where our oceans were evaporating first somehow (even then it'd take hundreds of millions of years for the problem to compound into Venus-like conditions, not to mention current life forms would all die off or readapt as extremophiles by then)

>This planet once used to contain oceans and a strong magnetic field
Prove it.
Or at least present some compelling evidence.

>>16958673
>magnetic field
Earth and Venus are remarkably similar. If Venus was about 500°C cooler, it'd allow for a hard crust and convection and a cooling core, so it'd produce a reasonably strong magnetic field according to calculations (still weaker than Earth because it rotates slower.)

>once used to contain oceans
Besides the fact that it still has some water vapor and a lot of O bound to something else after losing much of its hydrogen, it was cold enough to have liquid water back when the Sun wasn't so intense. Again, it started out very similar in size and composition to Earth.

Where are the bomes? Show me the bomes

>>16958676
>if
>it’d
That’s the point. All the components are there but nobody ever turned over the engine.
The reason Venus is Venus and not Earth Jr. is because it never had a magnetic field.

>>16958680
Ah, indeed, it's pretty hard to distinguish the two potential scenarios given no evidence of the past magnetism would have survived at Venus' current temp and crust softness, though I'd ask what reason you have for assuming it did not have a magnetic field in its initial condition.

For the large initial quantities of water we do have some evidence besides the other residues I mentioned though. Venus has ridiculous amounts of deuterium compared to its hydrogen and especially its hydrosphere, which is consistent with photo-dissociation of water vapor. (Deuterium was left behind while regular hydrogen leaked into space)
And the Sun being much cooler 4 bya is pretty certain.

>>16958660
>>16958667
The Venusian model was widely taught in the late 80s early 90s as a "runaway" greenhouse effect. Gavin of NASA infamy had already distanced himself from that model by the late 00s early 10s

>>16958684
I should add, if hydrogen had been present mostly as pure H2 early on, it'd have escaped long before being fixated in the compounds currently present in the atmosphere (especially with a thin atmosphere to hold it, assuming no water vapor greenhouse), and the mere presence of so much O in Venus' current atm implies it was probably bonded as water back when there was H to bond with. All that C and S and co was released gradually by volcanic activity.

Climate change will make a lot more species go extinct, but not *all* species. Evolution keeps up with rising CO2 levels, and future people will probably just breathe through portable CO2 scrubbers and walk around with air conditioning units if the problem gets bad enough.

>>16958705
Is there a formula that pegs evolution and/or extinction to rising CO2 levels?

>>16958707
It'd be too goddamn complex even when considering a single particular species, it'd necessarily rely on observed/estimated rates from past extinction events.

>>16958709
>It'd be too goddamn complex
There's the rub

People are retarded, yes, but some countries like China are trying to significantly curb their CO2 emissions.

You want us to do the same thing in America (assuming you're a burger)? Get MAGA the fuck out of the government. Literally everyone else realizes just how utterly idiotic it is to keep relying on fossil fuels instead of transitioning to electric vehicles. Everyone realizes how retarded it is to cut funding for climate and Earth-based science and to not protect our national parks. Yet MAGA keeps pushing this shit because "Murricaa".

Everyone else with a functioning brain realizes this is an existential threat.

>>16958831
But MAGA is literally the electric car guy and the other team are the people who blows up electric car dealerships and vandalize the electric cars because the electric car guy is adjacent to Donald Trump, the principal character in your cult of personality.

>>16958831
holyfuck you are retarded and this entire thread is retarded, just take a look at chinas C02 numbers and you tell me if they are really trying to curb their c02. Show us the numbers bitch

>>16958835
MAGA is not 'literally' the electric car guy, he's one asshole who doesn't even really care about the environment so much as he does about lining his own pockets. Else he'd use his wealth to strongarm Congress into not making retarded decisions.

Besides that, your narrative is so lacking in substantial evidence and cherrypicked that it's safe to assume you are severely misinformed, if not outright retarded. If Trump cared about the environment, care to tell us why Trump and MAGA are so deeply aligned with the interests of oil companies (while not even being very good at that)? Tell us why he significantly cut funding for the EPA and its work for environmental justice? If he cares about the environment, tell me why he pulled us out of the Paris Agreement TWICE now?

Fuck you're fucking retarded.

>>16958837
I'm not in your Trump cult of personality and don't care to debate crazy people who are. One team has the electric car guy, the other makes violence against people with electric cars. That's how it looks to a normal person who isn't in your cult of personality that worships and mythologizes the reality TV game show host Donald Trump.

trumo and musky have divorced long ago

Maybe they are completely destroyed after millions of years?

>>16958872
The reality TV fight they had was so blue team Trump cultists like the other anon would destroy less property and kill fewer people. Musk himself is still a red team Trump cultist who believes the country would be magically destroyed somehow if the other club of billionaires had won the election.

please, post the countries with the most solar power, both in raw numbers and per capita.

>>16959180
China has almost 3x the CO2 emissions/capita of Mexico or Thailand, countries with similar GDP PPP per capita. China has nearly 10x the CO2 emissions/capita of India, a country with about half the GDP PPP/capita and not exactly known for setting examples in pollution management.

Also I'm not even American, you assblasted thirdie.

>muh solar power
post it yourself if you care so much

>>16959184
here comes the big ass cope

>China has almost 3x the CO2 emissions/capita of Mexico or Thailand
what's the population of china?
what's the population of the US, EU-27, Japan...?

>>16959186
>/capita

>>16958648
Not taking a side in this argument, but do you think there would be any traces of us on Earth if we disappeared, and something else observed the planet from space or took surface samples of it in a million or billion years? Probably not IMO

>>16959187
yeah, and common sense would have anyone believe that a country with such a big population and produces so much of what the world consumes to have higher emissions. but they still don't.

>China has nearly 10x the CO2 emissions/capita of India
what do they produce? cow dung?

what are you doing here, btw?

It's all cope. Pretending we have any real influence on the inevitable outcome, which is that we will go extinct. We might have a tiny bit of influene on when we all die, but probably not even that.

>>16958707
The period of greatest biodiversity in Earth's history with the largest megafauna in the history of life in the known universe coincided with a period of far more massive CO2 in Earth's atmosphere than even the worst predictions of climate change.

>>16959188
Human artifacts will likely remain in and around the solar system at large for a million or more years provided we keep doing space shit instead of doing what libs want and spending it all on third worlders so they can shit out infinity trillion children to come here and defraud Minnesota welfare systems.
