How else do you explain:

1. Temperature increase of about 0.5C since the 1970s,

2. Variations in radiation and temperature across the surface planet that are generating strong winds which can stir up giant dust storms, trapping heat and raising the planet’s temperature,

3. Widespread changes, with some areas becoming darker… and when a surface darkens it absorbs more heat, eventually radiating that heat back to warm the atmosphere,

4. The rapid climate change is happening so fast that the planet could lose its southern ice cap.

Is it human driven or a natural phenomena?

Considering this global warming is occuring on Mars, I doubt we can blame this one on Republicans driving SUVs.

1. Tex,

   While this is perhaps clever misdirection - it is misdirection all the same. Nobody making the case for global warming denies that there is a pattern throughout geologic history of warming and cooling. Rather, they are concerned that the current trend disrupts that pattern (i.e., that it is occurring at a quicker rate than is typical - and that the percentage of co2 in the atmosphere excedes that of any era - making it likely that the trend will not only continue, but increase). By contrast - with Mars, we have no evicence that what we are currently seeing is - or isn’t - part of a larger trend (the trend for mars might include the melting of the polar ice caps every 50 years - we just don’t know). So - if you are going to debate the issue of global warming - you will have to keep your attention. . .down to earth.

   He’s right, TR. After all, by pointing out that the same thing is happening on Mars, despite the absence of Hummers and Rovian polar cap melting machines, undermines that whole “man’s frying the Earth” chicken littleism.

   So for the sake of the leftards’ logic-starved sensibilities, could you ignore that phenomena on other planets? Thanks in advance.

3. Dear Crush - This is perhaps the stupidest point you have ever made. Did you even read my post? YES - there is a pattern of warming and cooling on the earth. There is - then - no suprise that there is one on Mars. What we don’t know is whether or not the Mars pattern is an anomaly. While the earth pattern certainly looks like one.

   What logic dictates - is that we don’t have enough information about Mars to make an analogy to what is taking place on Earth. You really are a right-simpleton aren’t you??

4. Wrong! I not only think this can be blamed on mankind, it can be blamed on Bush! And soon.

5. Jerkagain,

   You’re right: Global “warming” on Mars is an anomaly, but global “warming” on Earth isn’t. How silly of me to not see it. It’s just a big coinkidink.

   Dipsh#t.

6. Please - Crush. Just read my argument and try to understand it. It really isn’t even about global wamring per se. It is more about logical reasoning.

   And it is simple. So simple that it really isn’t even debateable. Yes - global warming is a natural phenomenon - here on Earth - as it is on Mars. NOBODY - on either side of the current divide over the issue - debates this. Show me a single environmentalist who says that global warming isn’t in some part a natural phenomenon?? A single one??

   Moreover, if this article suggested that Mars had moved outside of its normal pattern - THEN THE COINKIDINK WOULD MEAN SOMETHING. But it SIMPLY DOESN”T SAY THAT - despite your best efforts to make it say that. And so again — I ask you to find a SINGLE article that says that mars has moved outside of its natural pattern. The link provided doesn’t say this. And so the link provided is irrelevant to the debate. It neither proves - nor disproves - anything - on either side of the issue.

7. Then why is the Left advocating economy-killing measures to offset a natural phenomena?

8. Because - in addition to believing that global warming is in part a natural phenomenon (the part which makes the reference to Mars irrelevant) they also believe that it has sped up in recent years to an unnatural degree.

   Really - Tex - I laid this all out above. But you fake left - and then fake right. Now - no doubt - you will once again refute the position that there is something unnatural about global warming by again citing mars.

   To put it as clearly as possible - Global warming scientists believe that global warming is a combination of both natural factors and unnatural factors. Citing Mars only affirms what global warming scientists already admit –i.e., that it can be a consequence of natural factors.

9. To summarize ALL of djernigan’s comments: “Man’s activities are the primary cause of global warming. Do not look at the planet Mars behind the curtain. The debate is over. There is NOTHING left to discuss, let alone debate. Just pay your carbon taxes and shut up.”

10. Gotta love this tex.

11. “Then why is the Left advocating economy-killing measures to offset a natural phenomena? ”

    I assume that you refer to the Supreme Court telling the EPA can no longer just forget to enforce the Clean Air Act?

    The issue is two-fold. First there is the non-natural part of the current heating pattern. All indications are that temperature changes wouldn’t usually go this fast without human intervention. The second is that there is a big difference between this climate change cycle and all the previous ones: we’re living through it. Mass extinctions are a natural phenomenon, as the fossil record shows (unless you’re with the Young Earth crowd), but that doesn’t mean we just have to let it happen.

12. Thanks enforendil. Given the level of debate in this coutry over serious topics - some times I think that a natural extinction might not be such a bad thing.
