| 522278 | 2007-02-03 11:39:00 | Hi there all. While I think we should do all we can to reduce pollution I don't believe all the scaremongering we are getting from the press these days so here is a link (www.canada.com) to an interesting article. |

| 522279 | 2007-02-03 12:23:00 | Hi there all. While I think we should do all we can to reduce pollution I don't believe all the scaremongering we are getting from the press these days so here is a link (www.canada.com) to an interesting article. Oh dear. We've just been given really important info about global warming with a statement from a gathering of acknowledged world experts. Finally, the " real oil." This is not "scaremongering" from the media. It's as authorative as you can get. It has been carried by all major world media from the BBC down - and rightly so. They would be lacking in their duty not to. Your link is to a small-time source quoting one writer about "global warming " on Mars. If you want to raise the subject, surely it makes more sense to quote what's happening closer at hand? (Sorry about the rant. It's just that I don't believe there's media "scaremongering" right now. I think the fact that human activities are contributing to global warming has just been adequately enough confirmed to finally quench the scoffers. And the more noise the media makes about that, the better) Let's try to fix it here before worrying about Mars ... please. P.S And before you ask. No, I didn't even bother to read it, once I regsitered it was written by a nobody compred with the world forum - which shows how I felt. Normally I'd criticise anyone who commented on something they hadn't read. |

"It is no secret that increased solar irradiance warms Earth's oceans, which then triggers the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations." Dr. Abdussamatov goes further, debunking the very notion of a greenhouse effect. "Ascribing 'greenhouse' effect properties to the Earth's atmosphere is not scientifically substantiated," he maintains. "Heated greenhouse gases, which become lighter as a result of expansion, ascend to the atmosphere only to give the absorbed heat away." The real news from Saint Petersburg -- demonstrated by cooling that is occurring on the upper layers of the world's oceans -- is that Earth has hit its temperature ceiling. Solar irradiance has begun to fall, ushering in a protracted cooling period beginning in 2012 to 2015. The depth of the decline in solar irradiance reaching Earth will occur around 2040, and "will inevitably lead to a deep freeze around 2055-60" lasting some 50 years, after which temperatures will go up again. now i have heard that the earth has a natural cycle of heating/cooling, and has had since panama isolated the atlantic from the pacific, but the evidence shows a drastic (30%) increase of CO2 in the atmosphere, among other 'greenhouse gasses', coinciding with the beginning of the industrial revolution. is it really our fault or coincidence? IT DOESN'T MATTER why? because if we decide it's coincidence, and we're wrong, we're f*cked. same thing for the dwindling oil reserves; some say we have 10 years left, some say 50, some say 100. either way if we aren't prepared when/if we do run out we'll sure wish we had actually made an effort. we never regret the things we do as much as the things we don't. better safe than sorry. FACT: the energy given off by the sun has increased 25% since the beginning of the earth, so i'm sure that has a part to play, but that's over BILLIONS of years, not just over a hundred. |

| 522281 | 2007-02-03 18:57:00 | The fact that Mars is also warming is very relevant. Why? Is it all the Martians and their cars and coal fires? Large changes in climate are not unknown on this planet. Whether we have hastened it or not. Sooner or later we will be extinct too, the planet will still be here. Just ask the dinosaurs. |

| 522282 | 2007-02-03 20:49:00 | Climate is a chaotic process. It's the result of the nonlinear interaction of many different forces. I scoff when people tell me they are "certain" about anything related to a chaotic process. We are just not clever enough yet. That's why we cannot forecast weather more than 7 days ahead - what happens that far ahead depends on tiny perturbations to the atmosphere today. A butterfly flapping its wings in the Amazon jungle can lead to a tornado in Kansas next week. Any scientist who tells you they are "certain" about anything related to climate is a fool. |

| 522284 | 2007-02-03 21:55:00 | Amusingly, the same website also has this story (www.canada.com) which rather contradicts the one mikebartnz refers to along with several others sympathetic to the "It's us that's causing Global Warming" theory. Is the media scaremongering or just trying to bring a relevant point to everyones' attention? When even G W Bush seems concerned about an environmental issue it must have some substance... |

| 522286 | 2007-02-03 22:15:00 | Seems to me that the two biggest culprits, America & China, do not belong to the "Warming Club". Also seems to me that a few cows fluffing in NZ is nowhere near as bad as the aformentioned countries. PJ | Poppa John (284) | ||

Actually, climate is not a chaotic process - what you are taking about is weather (which is unpredictable and 'non-linear') not climate (which is the average effect of weather over time but otherwise not related to it and entirely linear) Global Warming is a serious issue so it's helpful to distinguish these kind of terms. |
