Nonsense, filling an atmosphere with pollutants over decades couldn't possibly have any effect.

at least the mouth breathers have shifted from complete denial of the problem, to just utter ignorance of geological time. I guess that is progress.

In one of the most unusual -- and highly unlikely -- first-contact scenarios, aliens would be able to recognize us by the level of greenhouse gas emissions we pump into our atmosphere. Not only that, according to a hypothesis put forward by researchers affiliated with NASA and Pennsylvania State University (though not directly tied with either institution), but aliens may use that as cause to wipe out the human race. In this bizarre set of circumstance, aliens view human advancement as a destructive force spiraling out of control. To avoid the threat of a future adversary, extraterrestrials clear out the competition. BLOG: TO SAVE THE GALAXY, DESTROY HUMANITY

The fact that it is close to the sun

Re: The fact that it is close to the sun


May 1, 2016, 11:31 AM

actually no, that has little to do with it, but i am not surprised you believe this.
it is the density of the atmosphere that holds in solar radiation. After-all, our moon is freezing cold.

badge-donor-10yr.jpg flag link military_tech thumb_downthumb_up

uh no crap


May 1, 2016, 11:45 AM

That is why mercury isn't as hot as venus. Mercury's atmosphere was blown away by the sun. You know that sciency thing

I know you really want to build an argument that atmospheric CO2 levels have no effect on climate change, but you would be wrong.

Re: and -200 degrees at night


May 1, 2016, 11:53 AM

True.


I can understand people that believe we're not 100% to blame but don't understand people that say were 0% to blame. We do share some blame. We're destroying our environment.

Well, at least were doing somewhat better than just a few years ago.

On the dark side. On the daytime side, it reaches temps we don't want here. LOL 250+f

According to him the sun has no effect lol


May 1, 2016, 11:51 AM

So if venus was where Pluto is, it would have the same temp if it had the same composition. I love this.

"That has little to do with it." He didn't say it had nothing to do with it.


Solar intensity does effect climate, but that isn't what's been going on the last several decades.


Well, I'm grilling for the family, so I'm out of this debate. Y'all have fun. ;)

Re: According to him the sun has no effect lol


May 1, 2016, 11:59 AM [ in reply to Re: According to him the sun has no effect lol ]

I said distance from the sun had little to do with it. 5" off the surface of the moon it is absolute zero. without an atmosphere to trap heat, it can not exist.

Xtiger only proved my point that changing the desnity of our atmosphere is not a good thing. But where most Deniers get lost, is that subtle changes of 2-3 degrees will have profound affects on our weather patterns and glacial melt. And that the changes we have measured in the past took 10s of thousands of years, not one century.

But you would make a good oil lobbyist, otherwise I do not understand what dog you have in this fight.

co2 makes .04% of our atmosphere


May 1, 2016, 12:04 PM [ in reply to Re: According to him the sun has no effect lol ]

So going to .05% is gonna send us into oblivion. Got it. And ys venus being close to the sun is 99% of why it is so hot. If it was at Pluto, it would be an ice planet

Re: co2 makes .04% of our atmosphere


May 1, 2016, 12:25 PM

exposure to solar radiation, not distance from sun, light does not decay in a vacuum.. And course, the radiation needs a medium to trap it. I know these are tough concepts, Hopefully this is the last time I have to explain it.

badge-donor-10yr.jpg flag link military_tech thumb_downthumb_up

I already know that. Never said that but


May 1, 2016, 12:48 PM

You're trying to make that your talking PT. Atmosphere does not mean co2. Atmosphere is not my PT at all. If the earth was where venus was, earth would turn into a mass of heat. Shoot even solar flares increase our temp. Aka the sun and it's heat

Went back through the thread, I was mistaken. I didn't realize y'all were talking about atmosphere.

Balm is right, temps fluctuate on the moon so wildly because of lack of atmosphere. If the earth didn't have atmosphere, we'd have the same large fluctuations.

2024 orange level memberbadge-donor-05yr.jpg flag link military_tech thumb_downthumb_up

I never argued that


May 1, 2016, 12:42 PM

That is why mercury is cooler than venus.

Wonder if they evolved or were created?


May 1, 2016, 9:48 AM

Seriously - because evolution is so easy that not only, on our own little garden in the grand landscape of the universe, did evolution bring to life the various animal kingdom figures, and the aquatic kingdom figures, it also gave us plants and trees. And of such variety it is mind boggling - until we realize it is just evolution. Now to think it didn't just happen here! Wow!


Are we having fun yet? :)

Re: Wonder if they evolved or were created?


May 1, 2016, 10:53 AM

I definitely have fun contemplating such things.

Would be awesome to make contact or at least discover other civilizations (or any life really) although that is extremely unlikely.
