Wait - I thought Climate Change was the work of the Lizard aliens trying to terra-form the planet to be more like their home planet? Then again, it has been a while since I heard "Coast to Coast AM", so the prevailing (nutjob conspiracy) theory may have changed.

No shiat. The Greys aren't stupid.  Given the choice, I wouldn't want to spend my precious vacation time on holiday in the intergalactic equivalent of Detroit either.

This makes sense. Do you go make friends with the guy with cars up on blocks in his unmowed front yard, with gutters clogged/falling off the house, various vermin or ugly children running around?  No!  You don't want him to invite himself over to your house and muck that up. Same deal with aliens - we're the trailerpark of the galaxy, folks, and they know better.

The surest sign that there's intelligent life out there is that they don't contact us.
 
2014-06-10 08:47:29 AM  
Nah, the aliens will wait until everything is gone before taking over.
 
2014-06-10 08:49:56 AM  
There are no advanced alien civilizations. Just strong AI instances that have replaced their creators as newer better species tend to do.

And why the fark would they bother with us, even if interstellar travel was viable in anything but the most absurd sci-fi fantasy?

The article is about the idea that other worlds may not have experienced the geological and biological changes that naturally balanced the increasing outputs of their suns. The idea is that Earth has been lucky that it is naturally stayed pretty steady temperature-wise. If the bulk of other worlds never stabilized they may not have had time to develop advanced life.

People who do not believe in God nonetheless populate the universes with alien life forms with all the attributes of "God." These aliens have all knowledge, can solve all of our problems, will unite the human race, and help us rise above our current mundane problems. They can do everything we used to attribute to gods. Just like religious gods there is no evidence that these aliens really exist, They are an article of faith, a faith arrived at by "logic" and mathematics even though no one has any idea at all of how wide spread intelligence is in the universe.really is. Even the fact that we have not been contacted is taken as a sign of their superior intelligence. In short aliens are gods for atheists. Thay are the very same cop out used by the religious. "Once the aliens arrive all our problems will be solved." is NO different than "Once we listen to god all our problems will be solved."  Stop believing in the tooth fairy people!

Some species has to be first, and the greatest cosmic joke would be if it were ourselves, as we are still nine-tenths in the retarded poo-flinging stages.

"Over the past half-billion years, a time period for which we have reasonable records of Earth's climate, the Sun's surface temperature increased by four percent, and terrestrial temperatures should have risen by roughly 10 degrees Celsius.   But the geological record shows that, if anything, on average temperatures fell."

This is what I like to call the "Al Gore paradox."

I thought it was because the aliens saw all of our streetlights and were terrified of our enormous armada of spaceships.

Well no shiat climate change is keeping aliens away. If you remember, global warming attracts asteroids. Why would an alien species that has developed interstellar travel want to deal with a planet that is sucking asteroids into it?
 
2014-06-10 09:15:32 AM  
Aliens do exist, and they have indeed visited Earth. They're here now. I saw a documentary about a small team of specialists with an extraordinary amount of unregulated authority who were responsible for ensuring peaceful coexistence between humans and alien life forms.

Delawheredad: They are an article of faith, a faith arrived at by "logic" and mathematics even though no one has any idea at all of how wide spread intelligence is in the universe.really is.


Nobody is using science to claim knowledge that aliens exist. Science is used to determine probabilities of aliens existing based on sets of assumptions and existing evidence - all fully disclosed. Individuals are free to chose how compelling they find these arguments.

Faith says: This is the way it is. No evidence. If you don't believe you don't have faith. Full stop.

These two methods are the opposite of each other.

I believe climate change is real, but I also believe that just as you have a lot of idiots denying it for political reasons, you have other idiots on the other side making all kinds of crazy assumptions for their own ends as well.

For example, the wild claim that Climate change would lead to this huge disaster were Florida goes under water.  I think we can all agree that is a silly notion.  Florida being under water would not be a huge disaster.

Take a marble in throw it into a football field. Then toss in a few more dump trucks of marbles. What you have there is a rough representation of the 'known' universe. The first marble is Earth. Find it.

We don't have the technology or equipment to see all that far into the universe, though we have discovered millions of other galaxies within the area we can see. Those are made up of billions of planets.

So, if aliens haven't magically arrived in their starships, it's probably because they're busy elsewhere.

Also, maybe they have and after a bit of surreptitious observation, decided we were more trouble than we're worth to bother with right now.

I mean, humans could set the standard for not being able to get along with anyone, especially each other, don't have the social conscience to keep from polluting their home beyond belief, have various, complex and often crooked political systems, apparently enjoy warfare and have managed, since discovering the atomic bomb, to set off well over 1000 of them, which has increased the 'normal' background radiation tremendously all across the globe.

After examining the business dealings across the globe, aliens probably decided it's not wise to do business with humans, who find numerous ways to screw each other over in the name of profit, write overly complex contracts and just love to sneak in things which are probably considered dishonorable.

Besides, give humans basically a harmless, technologically advanced toy and they'll find a way to turn it into a weapon of mass destruction. Look what they've managed to do with drones.

Not to mention that humans are experts at developing criminal activity out of the most innocuous situations -- even things as mundane as garbage disposal. They slaughter each other over little things like footwear and have no problem wiping out entire cultures if they decide they want their land.
Even the religions can't get along.

So, chances are, any advanced species has chosen wisely to avoid direct contact with humans until they either grow up or nearly exterminate themselves.

The human race is essentially schizophrenic.

Christopher Columbus bumped into an island full of natives who were friendly and impressed him with their physical beauty, their willingness to help, their society and their kindness. While he was admiring them, he was also estimating their value as slaves which he recorded in his records.

Yeah. There might be quite a few reasons why aliens do not drop by and introduce themselves. Humans might not be considered worth all the trouble interaction with them can cause.

Faith is the hope in things that have no evidence. The search for alien life is a faith-based excercise. If you don't believe in aliens, you have no faith.

machoprogrammer: I think man made climate change is real and all that, but stop blaming it for everything people. You aren't helping


They're not talking about man-made climate change.  Rather, the natural version.  Humanity just made it under the wire--if we had taken even 1% longer to arrive it's likely we wouldn't have ever arrived.  The Earth's ability to compensate for the warming sun is almost used up, when CO2 is as low as it can go (it has to be high enough for plants to absorb it or they'll quit absorbing it and it will rise due to volcanoes) the thermometer heads up.  Life will be able to adapt for a while but given the radical adaption needed it will favor the small organisms with short lifecycles.

Now, is it just chance that we just made it, or is it that intelligent life usually takes longer to evolve than the time before the planet warms?

We can provide reasonable ball-park numbers on the physical terms of the Drake Equation.  Furthermore, we can reasonably estimate that the probability of life is high as it evolved basically as soon as it could on Earth.  Yet we don't see the ETs.  That means either *NOBODY* goes starfaring (unlikely) or one of the biological terms is tiny.

Looking at our evolution we see a few candidates:

1)  Multi-cellular life.  It took billions of years.

2)  The long term habitability of the planet.  We've taken big impacts in the past but no cosmic reset buttons have hit.  Estimates say a reset button should fall every 2 billion years.  This is lucky but not anything like enough to explain the empty skies.  Warming could very well be a limit, though.

3)  The development of intelligence.  From what we see this is more a matter of time between cataclysms--again, not likely to be the limiting factor.

4)  Intelligent life is self destructive.

One of these is a major killer.  Either we had a very narrow escape with the reaper in the past or he's about to show up--as in within the lifespan of many of the posters on here.

We are the the Galaxy's equivalent to a guy who lives in Kentucky on a long, dirt road who likes to affix explosives to his rusty old ford and shoot that shiat up.

No, any alien who knows how to navigate interstellar space travel is not going to want to deal with a bunch of knuckle dragging Cletis Dorks.

I believe we are on quarantine.

how depressing would it be if WE were the most intelligent life forms in the universe?  Ugh.

I always figured the answer to the Drake equation is that space is farking huge and finding a tiny blue planet around a yellow dwarf star is not the easiest task from light years away. And finding if it has life is harder than that, and visiting it is even harder.

FTFA:
These models predict that our planet should warm by a few degrees centigrade for each percentage increase in heating at Earth's surface. This is roughly the increased heating produced by carbon dioxide at the levels expected for the end of the 21st century. (Incidentally, that is where the IPCC prediction of global warming of around three degrees Celsius comes from.)
Over the past half-billion years, a time period for which we have reasonable records of Earth's climate, the Sun's surface temperature increased by four percent, and terrestrial temperatures should have risen by roughly 10 degrees Celsius. But the geological record shows that, if anything, on average temperatures fell.
 

Gee, one might be inclined to think that computer models are nowhere near complex enough to accurately predict future climate temperatures. But that won't stop the chicken littles from crying out that the sky is falling and the temperatures are rising.

Our planet has therefore miraculously moderated climate change for four billion years. This observation led to the development of the Gaia hypothesis that a complex biosphere automatically regulates the environment in its own interests. However, Gaia lacks a credible mechanism and has probably confused cause and effect: a reasonably stable environment is a precondition for a complex biosphere, not the other way around.

Surely, like a motor vehicle, you just need a starter motor (life) and then it is self supporting as long as there is fuel (the sun). It will tick over fine and keep to the same speed to within a few hundred rpm even when rolling up or down a slight hill for example.

life is a credible mechanism. As long as there are animals making co2 from oxygen and plants.

more plants=less co2 so therefore cooler
cooler=less plants
less plants=more co2 so therefore warmer
warmer+more co2=more plants

rinse repeat etc

The biosphere didn`t get complex until life made it stable...

first we had (IIRC) bacteria that ate methane and shat oxygen which was poison to them and so killed them. Then we got things that breathed oxygen and put out co2 so things that breathed co2 evolved. At this point we have the co2 cycle in place which regulates the climate allowing a more complex biosphere which would regulate even more.

I may well have missed some parts and got some wrong but AFAIK that`s pretty much it.

Now we panic if the temperature changes by less than 2 degrees...

I hadn't heard the bit about the sun warming before - very interesting.  In regards to our 'luck' here on earth there is also the protection from the Earth's magnetic field.  No matter what we do to the atmosphere on Mars we wouldn't be able to walk around unprotected on the surface because it is lacking that protective shield.  I've also heard the case made that our (relatively) obscenely large moon and the tides it creates helped with the genesis of life on earth by creating coastal areas with varying (including zero) water depth.  It takes a lot of specific things to encourage genesis and support evolution for billions of years to get to humans - if we assume other advanced life requires a similar amount of time to evolve then it's likely extremely rare even with so many stars and planets available.
