My school project, third documentary, 1st on Global Warming. I worked really hard on making this. I wrote it, edited it and filmed it. It has also been nominated for the 2008 IVIE californian film awards.

Very nicely done. wink 4/5

I personally believe that Global Warming exists, and is happening, but I already heard something rather interesting, which would be the cause of ice ages and previous planet warmings. They say that the Earth is always changing its angle, which will result in having the sun hitting it a different way. Thus, the planet'll sometimes be colder, sometimes warmer.

The person who was presenting that idea (on the news) basically said that Global Warming was rubbish, that really it was all normal and had already happened before.

About the made-up record-breaking hot years: They might have been made up, I don't know, but what I do know is that practically every year, we get less snow and warmer summers (here, our winters usually go up to the -50s for four or five days, then start getting warmer again; this year, I think we might have reached -40 for a day or two, then started getting warmer again. It's really scary, actually. You could say that it's just an anomaly, that next year it'll be fine again - which is possible - but it's been slightly warmer every year for a while, now.)

About the polar bears, it's true that they mostly die of hunters, but then again the fact that 14 of them (if that's not the exact number, it's because I watched your film yesterday) die from global warming each year is inexcusable. Especially if global warming is, in fact, human-made.

But yeah, them being hunted down obviously doesn't help.

First off, you did a decent amount of research into this, which I appreciate, but I wouldn't say it wasn't wholly biased... All of your sources were from people who think global warming isn't true... you could have looked at the scientific sources as well for a fair discussion of the issue.

The film is decently made, you present the argument in a well organized way, but you have an awful lot of text and slow down time. It could definitely be more visually appealing. You also need to cite your sources for animations and images (like the windmill schematic) that I presume are not your own.

As for the issues, I'll start with Plainly's comments. Plainly is talking about the obliquity and precession of the earth's axis, two phenomenon that are part of what are called the Milankovitch cycles (http://en.wikipedia.org/wiki/Milankovitch_cycle), whereby the earth's axis tilts and precesses over 40,000-100,000 years. These cycles have historically been linked to slight shifts in earth's climate and the cyclic nature of ice ages (we've had at least 7 major ice ages in the last million years, the last of which ended about 15,000 years ago). If we are to believe the past trends of milankovitch cycles and ice ages, we should really have been entering a cooling cycle (ice age) in the last 1000 years or so, but some scientists think that anthropogenic methane from rice paddies and cow belching beginning about 6,000-8,000 years ago (the first human agriculture) kept the earth from going into the cooling cycle, and now CO2, Methane, chlorofluorocarbon (CFC), and ozone (O3) emissions are accelerating that warming in an unstoppable fashion.

So global warming began with our ancestors thousands of years ago when they started growing crops, and we are continuing the trend. You can see this (and the milankovitch cycles) if you look at the vostok ice core temperature and CO2 chart (http://en.wikipedia.org/wiki/Image:Vostok-ice-core-petit.png). This chart is also one piece of evidence that over the course of the earth's history, CO2 really is linked to changes in global temperature, and that's one point on which the guy from the weather channel is very wrong. He said that CO2 is in very small concentrations in the atmosphere (which is true), but even so it has an inordinately high affect on global climate, because it lets through sunlight in the visible light band (the one at which most light comes in) but absorbs infrared light re-radiating from the earth, re-radiating the infrared light, some of which heads back towards the earth. Nitrogen has huge concentrations in the atmosphere (almost 70%) yet it is almost entirely inert (it doesn't do anything).

One important thing to mention (plainly and others) is that annual changes in the weather, like a really hot summer, or winter with no snow, are not good indicators of global warming. What you need to look at is the trend in annual average temperatures, like this one http://en.wikipedia.org/wiki/Image:Instrumental_Temperature_Record.png so that you can see the overall climatic shift over hundreds of years (way more than your lifetime). There are other climatic effects (like El Niño/La Niña) that can cause annual variation (like the really cold winter in the continental US this year), but these are only on a decadal timescale which is why there are all those little bumps in the temperature chart.

The polar bear issue may be something over exaggerated, since polar bears have been shown to be able to adapt to climate change (talk to Nikita Ovsyanikov, russian polar bear scientist). But there are other major issues associated with climate change which do affect people on the scale of hundreds of thousands or even millions: with sea level and storm intensity and frequency rising, we're likely to see more storms like Katrina (which did an awful lot of damage), like the cyclone in Burma right now, and others, which are displacing and killing thousands in the poorest countries in the world. Most of Bangladesh, for example, is at sea level and at extremely high risk of any storm or sea level change.

In drier parts of the world, like australia, the water supplies for major cities like Perth, Melbourne and Sydney are dwindling in large part due to climate change, and if more efficient water use and catchment policies are not enacted, millions of people will be affected.

Hopefully this gives a little bit of insight on the issue, which is really much more complicated than any news outlet pretends.

I welcome further comments or questions.

I must ask you this question have you heard of Global Dimming?

If not then you are not qualified to do an article on global warming.

If you have heard of global dimming and preceded to do this article then I must say you do not understand the magnitude and effects of Global Dimming.

Please take the time to read these articles. I am certain you will learn something new and extremely important.

Lou–
Before I address global dimming, I should make a point: just because someone does not know a certain part of an issue does not mean they are not qualified to talk about the issue. For example, if you didn't know about the refraction of light dependence on wavelength, you would still be able to say that the sky is blue, even though you don't know why.

Ok. Global Dimming. You say that if I haven't heard of global dimming I shouldn't write about global warming, and if I have heard of it...then I don't understand it. Please explain what you mean.
As far as I was previously aware (and the wikipedia article says the same thing), global dimming is a phenomenon whereby particulates, aerosols, ozone, etc. in the atmosphere increase the earth's albedo (i.e. reflect more sunlight), thus decreasing the immediate effects of greenhouse warming. However, the particulates that cause dimming are short-lived with a lifespan on the scale of 10s of years, whereas greenhouse forcing gases like CO2 and CFCs can stay in the atmosphere for as long as 1000s of years. Thus, if we work hard on decreasing pollution (by driving electric cars, for example), the dimming particulates will decay over a few decades, and then the extremely high CO2 concentrations will lead to exorbitant greenhouse warming.

So in summary, global dimming is a short-term effect masking the more serious long-term nature of global climate change.

Is that what you were asking?

The film was well done.

I'm not quite sure what age group you were aiming at. But I do agree about global warming being a bit over hyped. I studied Global warming at college in the UK and my teacher said that we must remeber, that the scientissts are not sure as to wheather global warming is happaning or not.

We need CO2, H2O (which are green house gases) to give us a green house effect. Otherwise there would not be any ability for the planet to keep warm.

Also, something that really bugs me. CFC's are not green house gases. They stop O3 (Ozone) from forming. This Hole in the ozone layer allows more than the normal amount of UV (which is short Wave EM radiation) on to the earth, which warms up the land and emits heat (Long wave EM radiation).

You could have also bulked out the film by adding more about renewable fuel sources. Geo-thermal, Solar, Tidal, Gravertaional (can't think of the correct term), bio-ethernol and Nuclear (yes it is classed as a renewable source because it uses a very small amount of fuel to make a hure amount of energy.)

Your film was trying to highlight the more pressing problems our world faces. this was very good, as too many say they will help the environment because it is easier to do that than working to fix the more imediate problems we face.

Januc. CFCs are greenhouse gases. They also happen to destroy ozone leading to the antarctic ozone hole, but they are potent greenhouse gases – up to 13000 times more potent than CO2.

From wikipedia:
"Chloro fluoro carbon compounds (CFC, HCFC), CFC molecules–
Chlorofluorocarbons (CFC) are compounds containing chlorine, fluorine and carbon only, that is they contain no hydrogen. They were formerly used widely in industry, for example as refrigerants, propellants, and cleaning solvents. Their use has been regularly prohibited by the Montreal Protocol, because of effects on the ozone layer (see ozone depletion). They are also powerful greenhouse gases, in terms of carbon dioxide equivalence (over a time period of one hundred years) between 5000 and 8100 per kg. [1]"

I dont beleive this Global warming flap. The earth goes through cycles and we just happen to be in one. There are many Scientist that dont beleive in this whole global warming idea. The problem, if you dont beleive in global warming and get others to believe it, then funding for it will be cut. No one wants to lose their funding. Plus it would make all our political people look like idiots...so global warming continues.

Sorry guys, really i didn't realise that CFC's trapped heat as well as breaking Ozone.

The idea about global dimming is also intresting, because as the planet heats up, there will be more cloud keeping the earth warmer. but the clouds will also reflect a lot of the UV. This could mean that the earth will cool again. Or according to Lovelocks Gia theory. As CO2 increases, then vegetaion will increase to absorb the extra CO2.

Okay, so I understand that we don't all share the same opinions/beliefs on ol' Global Warmin',

But even if you don't believe in our message it is my best work (Editing and filming wise), and we also got a famous person (Sort of), and I was 14 when I made it, so go easy on me.

I just tried my best,

So, Documentaries are made to voice your opinion on a subject matter and I don't find it nice that ppl are just voting 1's because they didn't agree with our views, we made a good movie, maybe the content is wrong in your opinion, but we did make a good movie, heres my proof:

http://www.ivieawards.org/ivie08/9-12doc.asp

It was a tie, but I still received countless bungles of software and trophies and free food and stuff. It was fun, I'll post the video of us receiving the award on saturday. Also, even though it says class production, that's just a mistake in misreading our submission, it was made my 4 people, written, Directed, shot, and edited by me, because I was in one of those types of groups this time.

We also got to stand up in front of 1,000 or something people and I choked so my partner (out of 4 who didn't do anything) stepped forward and gave his 'Speech', when you see the video you'll notice that everyone on stage is dressed up except for him.

David.

PS, you can watch 'Going Global', a video from the other class in our team (There are 2 teams in 9th grade),

Watch the whole 'complete-and-perhaps-over-confidence-in-making-a-good-movie' thing. Showing "proof" just makes you seem even more pretentious than the statement before that one. Which is a shame, because you really did make a good movie and it really is unfair and unjust for people to arbitrarily give it a vote of a 1.

But your point and feelings are scrambled when you throw in (probably mostly in emotion) a tad bit of haughtiness.

Also, your school is called 'High Tech High'? That is so badass.

Yeah, i was really angry, like really angry and just seeing the votes made me want to post this, I was angry due to off topic reasons.

i have been facing lots of criticism at school over my film (Especially since my advisor showed it to our advisory yesterday and the seniors haven't stopped insulting me).

And, I found out something very traumatizing yesterday about one of my family members current health conditions, so I was in that kind of mood of sadness when I posted, sorry.

I go to High Tech High Media Arts (In the High Tech Village), there are 5 schools, 3 high schools, 2 middle schools, all located in San Diego (There are some others that I know about) but the HTH thing originated at the village. I started at High Tech Middle in the 6th grade and now I'm about to finnish at HTHMA 9th grade (Almost 4 years!). The whole HTH thing was started like 6 or 7 years ago with the first one, just entitled High Tech High, then moved on with the middle school, HTH international, then high tech high media arts and high tech middle media arts, all of which somewhat funded by Bill Gates.

What?! That's sick (in a good way biggrin ). I've never heard of a place called High Tech Village in Cali. Now I want to go there just to see how "High Tech" it truly is.

As for my review of the documentary. I'd say that you could still do a lot more research on the subject. You did bring up some good points, though. But for the fact that you made this at age 14 and that it has some very good production value, I gave this 4 stars. Keep it up!

'Sawn-Dee-Ah-Go' is San Diego spelled phonetically, and with a garrish emphasis. It is said this way in Anchorman. Pretty self-explanatory, actually.... biggrin

It's very true that people should consider the movie as a whole and not just judge whether they agree with you or not.

However, documentaries are slightly different to fiction (even fiction that incorporates real themes). Fiction is inherently a completely subjective interpretation of a subject, and is very clearly from a particular point of view. As such, it's much easier to watch it, completely disagree with it, but still appreciate its filmmaking.

Documentaries, on the other hand, tend to present themselves as 'fact'. For this reason the content is under much higher scrutiny. It's not just about the filmmaking anymore: what's being said is of extreme importance, so if people disagree or think a documentary is plain wrong with its facts and conclusions, it's inevitably going to affect their vote.

There's also two types of documentary: one that presents a situation, but without drawing any direct conclusions (or, alternatively, make a specific effort to portray every side of the argument equally); the other take a particular side and argues it verociously, leaving no room for alternate viewpoints. The former would include BBC wildlife documentaries and responsible journalism, while the latter would include Michael Moore's work and tabloid journalism.

I'd say your documentary is closer to the latter style than the former, so it's inevitably going to provoke strong reactions. smile

However, well done for having a go at a particularly difficult topic!

Nice twist with the Polar Bear... people don't review ALL the facts. Good job.
