Global Warming / Climate Change Documentary

Global Warming / Climate Change Documentary



Hi, this video was put together and narrated by me way back as a ninth grade school project. I hope it gives you insight and more knowledge about global warming. Please only post constructive criticism.

Go to for part 2 of this video.

BTW: This documentary took over 100 hours to put together, edit videos, record videos, make narration documents, list bibliography, etc, etc, etc

This is Draft 5 you are watching

Please enjoy

And just a side note ; I got a 99% and was chosen as the best documentary in the school haha.

Thanks For Watching =)

Remember Part 2 is at NOT REVVER anymore (Revver is constantly down, and the video quality has degraded, blip TV has FULL HD and is much better)

Thanks

  1. According to the Vostok Ice Core Records, CO2 level changes have followed Earth's overall temperature changes at an 800 year lag for the last 800,000 years. That means that our current CO2 levels are the result of Earth's overall temperature 800 years ago. World leaders have convinced their dependents that this works in the reverse order, relatively quickly, and that we are to blame, so that they can tax us out of a false shared guilt in order to be able to afford to "fight" climate change, an unstoppable natural cycle. The following is the source of this information:

    Period of Record
    417,160 – 2,342 years BP

    Methods
    In January 1998, the collaborative ice-drilling project between Russia, the United States, and France at the Russian Vostok station in East Antarctica yielded the deepest ice core ever recovered, reaching a depth of 3,623 m (Petit et al. 1997, 1999). Ice cores are unique with their entrapped air inclusions enabling direct records of past changes in atmospheric trace-gas composition. Preliminary data indicate the Vostok ice-core record extends through four climate cycles, with ice slightly older than 400 kyr (Petit et al. 1997, 1999). Because air bubbles do not close at the surface of the ice sheet but only near the firn-ice transition (that is, at ~90 m below the surface at Vostok), the air extracted from the ice is younger than the surrounding ice (Barnola et al. 1991). Using semiempirical models of densification applied to past Vostok climate conditions, Barnola et al. (1991) reported that the age difference between air and ice may be ~6000 years during the coldest periods instead of ~4000 years, as previously assumed. Ice samples were cut with a bandsaw in a cold room (at about -15°C) as close as possible to the center of the core in order to avoid surface contamination (Barnola et al. 1983). Gas extraction and measurements were performed with the "Grenoble analytical setup," which involved crushing the ice sample (~40 g) under vacuum in a stainless-steel container without melting it, expanding the gas released during the crushing in a pre-evacuated sampling loop, and analyzing the CO2 concentrations by gas chromatography (Barnola et al. 1983). The analytical system, except for the stainless-steel container in which the ice was crushed, was calibrated for each ice sample measurement with a standard mixture of CO2 in nitrogen and oxygen. For further details on the experimental procedures and the dating of the successive ice layers at Vostok, see Barnola et al. (1987, 1991), Lorius et al. (1985), and Petit et al. (1999).

    Trends
    There is a close correlation between Antarctic temperature and atmospheric concentrations of CO2 (Barnola et al. 1987). The extension of the Vostok CO2 record shows that the main trends of CO2 are similar for each glacial cycle. Major transitions from the lowest to the highest values are associated with glacial-interglacial transitions. During these transitions, the atmospheric concentrations of CO2 rises from 180 to 280-300 ppmv (Petit et al. 1999). The extension of the Vostok CO2 record shows the present-day levels of CO2 are unprecedented during the past 420 kyr. Pre-industrial Holocene levels (~280 ppmv) are found during all interglacials, with the highest values (~300 ppmv) found approximately 323 kyr BP. When the Vostok ice core data were compared with other ice core data (Delmas et al. 1980; Neftel et al. 1982) for the past 30,000 – 40,000 years, good agreement was found between the records: all show low CO2 values [~200 parts per million by volume (ppmv)] during the Last Glacial Maximum and increased atmospheric CO2 concentrations associated with the glacial-Holocene transition. According to Barnola et al. (1991) and Petit et al. (1999) these measurements indicate that, at the beginning of the deglaciations, the CO2 increase either was in phase or lagged by less than ~1000 years with respect to the Antarctic temperature, whereas it clearly lagged behind the temperature at the onset of the glaciations.

  2. It is about variations from the norm! Here where I live in central CA, the seasonal temperature variation has become more moderate, fog has become rare, and rare summer rains are now a yearly occurrence.

  3. Want to know the biggest cause of global warming? Ready for it?……

    Livestock farming…
    Biggest contributor, and it was found that if all Americans chose not to eat meat once a day, it would be the equivalent of taking 19.2 billion cars off the road for a full year.

  4. Hi ThePaoloCV, I no longer have the script I used. In the future though, send me a private message so I can respond faster, I almost missed your comment! I will look for it tonight, and if I find it, I will send it. But I probably have long sinced deleted the file or have it archived someplace.

  5. @2wheels88 where in that comment did i just say that i agree with an 800 year lag? i was stating that ice core studies have a coarse resolution as they span many many thousands of years and that identifying a lag of 800 years should be taken with caution as it is very difficult to identify something like that on a finer scale. As for galileo, im not scared at all. in fact i have commented on topics that they raise in their poorly sited arguments. enjoy the lies of tony abbot

  6. Respond to this video…yet they identify a lag of 800 years. most ice core studies have an error of plus or minus a couple of thousand years so to identify an exact time lag of 800 years is completely inaccurate. its almost impossible to resolve such coarse data to a fine resolution like that. and ice core studies aren't the only evidence we use. foraminifera assemblages, speleotherms, tree rings. all data collected by these show a direct correlation of co2 and temp rise.

  7. Respond to this video… i get it from peer reviewed literature. you do know that anyone can make a website and publish whatever they want right? by the way. i dont listen to al gore, plus i dislike tim flannery and disagree with many studies he has made. dont judge climate scientists by people like them. oh and one more thing. those studies that claim a co2 lag. let me guess you read that of newscientist? ice core studies like that look at time periods of 100's of thousands of years

  8. Respond to this video… that dont know what they are talking about. of course it is the biggest greenhouse case. water don think you are all smart because you know that. do you know what it is the biggest? it absorbs infra red light, just like co2, but there is much more of it. however it has a much shorter residence time than co2 which is why it is ignored by climate scientists. you can say what you want but i study this. this is my degree. i dont get my data from websites that galileo site

  9. @2wheels88 the carbon tax is not penalizing tax payers. it is penalizing businesses. and yes they will increase their prices to offset it but the tax is built around that with many offsets so tax payers will be barely effected. big polluting businesses are run by corporate greed and agenda and do not care about the environment. you fault governments as the bad guy, in some ways they are but you cannot ignore big business. you think im brainwashed? i think you might be by the mining companies

  10. @2wheels88 i dont know what study you are talking about but every person i know that studies marine ecology or teaches it knows that coral bleaching has occurred in the great barrier reef numerous times as well as many other reefs around the world. i live in qld. the great barrier reef means a lot to me. and people like you who are selfish and ignorant are threatening the most biological diverse and beautiful community in the world and you make me sick.

  11. @2wheels88 im sorry but bleaching does occur on the great barrier reef and has caused a large amount of destruction there. bleaching events are mainly triggered when sst rises to ~31 degrees. at those temps corals expel their zooxanthelle and unless the temperatures return to normal those corals than starve. ocean acidification is also a huge threat to reefs caused by increased co2. so more co2 means higher sst and increased ocean acidification which causes bleaching. 1998 is the perfect example

  12. @2wheels88 um no thats not what im saying, pre industrial levels of co2 were ~250ppm and have risen to almost 400ppm this year and many studies have shown the corresponding temperature increase associated with carbon input. im comparing what is happening now to what has happened previously and im stating that the observed temperature increase that is currently happening is occurring faster than the largest observed natural rise in the earths temperature which happened over thousands of years

  13. @2wheels88 what makes you think co2 follows heating? how does warming temperatures contribute to co2 rise? show me the literature. do yourself a favor and look at research investigating the cenozoic hyperthermals. numerous times a huge amount of carbon was added to the atmosphere which was followed by a temperature increase of 5-10 degrees in only 10000 years.one of the fastest observed rates of temp increase ever. yet we have measured current temp rising by 1 degree in only a couple of hundred

  14. @2wheels88 show me the report that says bleaching does not occur. it most certainly does. NOAA has an entire section dedicated to monitoring bleaching events around the world. have you seen what a bleached reef looks like? its completely dead. also city pollution? that doesn't support your argument, it supports mine. where does that pollution come from? cars, trucks, power generation. with a tax it provides incentives to reduce those things thus IMPROVING pollution levels.

  15. @2wheels88 im uninformed? you have solar completely wrong. they do not store power in batteries, they use molten salt which which is very effective for thermal storage. that stored energy is then used to produce steam to power turbines. completely clean no heavy metals involved at all. the coal industry is not "clean" at all in anyway. by the way mining companies profit billions of dollars (which mostly goes overseas), a carbon tax will not cause them to switch to "third world" production.

  16. also you have no idea how green energy systems work. solar can work at night, there is extensive research going on right now on how to trap energy during the day to use it at night. and guess what. it works. wind turbines are very tall… for a reason because once you are high enough the friction of the earth doesn't slow wind down so its ALWAYS windy, tidal energy is built on the basis of the tides changing, tide comes it, spins turbine, tide goes out, spins turbine.

  17. @2wheels88 ok so you think those are big environmental problems, whereas scientists studying the amazon, coral reefs, conservation and ecology are more worried about temperature changes causing shifts in species ranges or even extinctions, or how about increased sst causing more severe coral bleaching events destroying one of the most diverse regions in the word. yes dumping unexplored ordinance is bad but they have regional effects. climate change is a global phenomena which is much worse

  18. carbon taxes are not bad like you think. you are the one being brainwashed by people with their own agenda. governments raise tax free thresholds to increase the money in everyones pockets to offset price increases, a certain percentage of that tax also goes to improving welfare and pensions to further offset increases. then another percentage goes into investing in green energy and technology. tell me another way to fund green energy? maybe BP or shell will…get real

  19. @2wheels88 it will come? it is already here old timer. wake up. solar energy is able to provide base load power and researchers are now on the verge of solving the problem of no sun at night time which is the major argument against it, geothermal energy can easily provide base load to a very large amount of the earths surface, dont forget wind turbines and tidal. the tech is here, but it hasn't received funding because the real evil corporations like the mining companies are preventing it

  20. @2wheels88 ok please tell me what is bullshit about it? What exactly makes you think that climate change, renewable energy and protecting the biodiversity of the planet is bullshit? You clearly have no idea how a tertiary (university) education works. They do not indoctrinate you, you are encouraged to perform your own research, create your own viewpoints and agendas and have your own opinions. Also nice to see you ignored my comment about the new research carried out about temperature change

  21. @2wheels88 I have no idea why you think i follow government funded research? for one i study climate change and environmental management at one of the leading universities in australia. one of the first things that i was taught was to identify bias and hidden agenda in literature. In fact i despise political agenda. look at that recent research by the berkeley earth project group. independently carried out investigation and find the same results as all over climate studies. you sir are a moron

  22. @2wheels88 I do do my own research numb nuts. the fact that you cant actually provide any relevant data proves that you are just another climate skeptic that really has no knowledge on this topic. im brainwashed? dont believe everything you see in the media mate….

  23. @atothek25

    Well, "global warming" isn't quite the right word, its climate change. Some places will experience an increase in temperature, while other places will experience the opposite. However, overall, the world is warming (avg temp is increasing), thus "global warming". Basically, the climates around the world are changing; deviating from the norm, but on avg, the temperature is increasing and we are experiencing more abnormal climatic problems (more hurricanes, etc)

  24. @Skaerin How do you know? For me, the heats been brutal this year (I live in Canada!). The sun goes through cycles, (hotter and colder). The hotter it is, the more sunspots there are (the more UV rays are released) the colder it is, the less sunspots there are. For a while there (the last two decades or so) there was little to no sunspot activity and since '09 there's been a rapid increase in sunspot activity. The sun has seasons just like earth, hotter cycle's mean more UV rays.

  25. I don't think CO2 is the true cause behind global warming! It's the sun! Think about it, it's a gigantic burning ball of fire in the sky! Don't you think that would somehow effect the atmosphere of earth? The climate changes all the time. To much or too little of anything could kill you, even oxygen. And since when was Carbon Dioxide bad? Plants need it to reproduce and make food! We humans are only in the way of these natural disasters! Let nature take it's course naturally ….

  26. @swanmcswan

    the sea levels cant rise because the ice is already in the water! the levels will only rise if the ice on land melts and finds its way into the ocean.

  27. 4 THINGS COULD HAPPEN AT THIS POINT:

    -If human induced climate change:
    is not real, and we do nothing, we won't waste any money, yay!
    -If human induced climate change:
    is not real, and we do something, we'll waste money, boo!
    -If human induced climate change:
    is real, and we do something, we'll have a new lease on life, yay!
    -If human induced climate change:
    is real, and we do nothing, we're dead, boo!

    It's a cost benefit thing, we're either dead, or out of money. WHAT IS LEAST BAD?

  28. @breyles

    After reading the comments that you are responding to, I agree with your statements! Thumbs up for your comments! It's always funny and good to point out the obvious faults in one's argument (false data, non-conclusive data, reliance on random myths, etc). Your comments made me laugh at the posts of the two people! 😀

  29. @allanallanson I have. So have thousands of scientists who have devoted their lives to their research. The earths tilt, distance from the sun, sunspots, blah blah blah and blah, do not come close to explaining the natural phenomena we are recording now, in the past or will in the future. (do you even understand the fundamentals of light radiation?) PS ice core samples do not "actually show" whatever falsehood your purporting as truth. A doco you saw does not make a scientific, robust argument.

  30. @Nightverssion
    Ur not the sharpest, imaginative nor grammatically correct one of the lot are you nightynight.. But its fun to point stare and laugh at you. Seems there's a whole lot of, well confused, racists in the world. Carpetcle et al, some perspective, the recent massive volcanic explosions that shut down air travel across the us and europe, in comparison to the amount of crap were pumping out EVERY SINGLE DAY, the volcano is a shining example of environmental sustainability.
