Global Warming & Mars

[quantumfireball2099]

I was hoping someone could shed some light on a short argument someone brought to my attention. I do not know if it's true or not, but I can't find much information online.

The arguement against man made global warming is thus;

'The earth is warmed by the sun. Sunspot activity changes the temperature of the earth. More sunspots = warmer earth, less sunspots = cooler earth. We've just come out of a period of more sunspot activity. Mars also has global warming right now. but guess what Mars doesn't have--- a greenhouse or people!!'

Thoughts? And I appologize if this sounds stupid to some of you, I do not have a science background, and pretty much just learn as I go.

Thanks.

The statement is correct that the activity of the sun affect the temperature of the Earth. It is also correct that the activity of the sun has been decreasing over the last few years, but this means the Earth should be getting cooler. It's not. This is why solar activity does not account for recent temperature trends.

I have no idea whether Mars is warming or whether it has a greenhouse atmosphere. I checked, Mars does not have a significant greenhouse effect because the atmosphere is too thin.

The temperature of th earth is influenced by several factors. This is almost fooling people with magic tricks, everyone believes that there is one and only one reason to affect what we see, it isn't it is a conjugation of different things super imposed. And it is a well known fact that green housegases significatively skew the temperature up due to an increased radiation absorption (which is the main source of heat and why our planet isn't stone cold, but the absense of carbon dioxide would stabilize the temperature at a more optimal level for life), even if other factors like solar cicles and sun incidence (driver of the seasons) makes the temperature woble up and down localy and periodicaly.

Like Aught3 says, we have just come out of a solar minimum (not a solar max like he claims) with the solar irradiance being somewhat less then the average (by about 0.1%).

It's a false analogy to compare the earth and Mars systems as they are very different. Anyway, a good discussion here about Mars climate change claim.

Netheralian, do you know if that graph is backed up by data taken from a science journal? I only ask because it's from Wiki... not always reliable.

He're is the source of that picture. http://commons.wikimedia.org/wiki/File:Solar-cycle-data.png

I have the source, but the person I showed it to doesn't trust it because it's from wiki.

Also he just mentioned how he doesn't believe in the greenhouse effect... so yeah... I'm going to give up on this debate with him after one more response.

EDIT: Nm, thanks Irkun, I see what you did. =) my bad

Appologies for leaving out the data source. And thanks to Irkun for covering for me...

Can you first ask him why he thinks it is that the Surface temperature of the Earth isn't 255K? That being the black body temperature of the planet.

Your quote is a lie. We're on our way our of a period of LESS sunspot activity. Your source is a lying shit-weasel. Here's an illustration that almost anyone could understand, from NASA:

You know what pisses me off about this? It takes about 45 seconds to type "Sunspot activity low" into a search engine and see the reality of the situation. FUCKING GOOGLE IT!!!! :evil:

Sorry Joe, It was in a 'debate' that I quoted that from, that was not a quote of mine. Thank you for the graph, I will use it as a reference =)

Here you go:



Of all the 'arguments' used by AGW deniers, this is by far the most retarded one.

 

[DeathofSpeech]

Oh look... With the greenhouse effect and the next solar maximum, we should be seeing people begin dying in significant numbers by... 2012. Because those crafty Mayans magically knew.... ummm yeah that. :roll:

The End is Neigh!!!

I guess I misunderstood the person I was speaking to, regarding sunspots. he clarifies his position as thus: "We just got out of a more sunspot activity cycle. Now there is no sunspot activity, therefore we should be trying to warm the earth to stave off the coming ice age (as if this were possible)"

He then links to http://www.iceagenow.com/growing_glaciers.htm

... I'm not sure what to make of it, but it sounds that just because some parts are growing/getting colder does not mean it's going to always be that way. He then goes off and says there is no way to get peer reviewed evidence against global warming because no debate is allowed on the topic... yeah, sounds like a creationist. I know :roll: I'm not 'debating' him anymore after that.

Unfortunately I linked him to greenmans youtube videos and he tells me; "That video is from a liberal site. IF CO2 is the problem, why don't they support nuclear energy? Because they are full of shit and are only after your money and freedom."

Yeah... :geek:

I didn't mean you, I meant people who have formed a solid anti-reality opinion based on a refusal to use the fucking Google.

Oh no, he is not a friend lol... =P

 

[lrkun]

Hehe, whether he is your friend does not really matter. Don't let it sidetrack you on the topic. Besides, if he or she makes a mistake, that is only normal. No one's perfect in an absolute sense.
