The Science Behind Climate Change (Documentary)


What is global warming? How did it start? How will it continue? What will happen to humanity? Will one day we’ll be gone due to our own ignorance? Global Warming is the continuing rise in the average temperature of Earth’s climate system Through the sudden use of factories, gas consuming cars and and other ambitions from fossil fuels the Earth’s temperature has rapidly increased since the beginning of the industrial age Global warming is a natural event but is being majorly contributed to by humans today, the quality of the atmosphere has been irreversibly depleted over time and if nothing is done about it, the Earth will ultimately swelter Americans are noticing changes all around them already summers are longer and hotter an extended periods of unusual heat last longer than any living American has ever experienced winters are generally shorter and warmer Rain comes in heavier downpours, tropical storms are much more intense, more destructive, and more frequent residence of some costal cities see their streets flood more regularly during storms and high tides In the in cities near large rivers also experience more flooding especially in the midwest and northeast So how does this happen? it is through something called the enhanced greenhouse effect which is the key ingredient of global warming. Greenhouse gasses include water vapor, carbon dioxide, methane, nitrous oxide and ozone Greenhouse gasses help regulate the temperature of the Earth the raise of the sun warm the Earth and the Earth reflects the radiated heat outwards. Greenhouse gasses prevent this heat from escaping from the surface of the earth with these gasses, the temperature of the earth would be unbearably colder. It is the sun that provides our planet with warmth and light, but the amount of energy that the Earth receives from the sun varies. Throughout the Earths existence the Earth has gradually changed its orbit around the sun. And with each orbit, the patterns of the energy that the Earth receives are different from each other. These changes have contributed to dramatic shits in Earths climate. The suns radiation comes in the form of light waves heating up the Earth. Some of the radiation that is absorbed and warmths the Earth is re radiated back into space in the form of infrared waves. But some of the infrared radiation is trapped by the atmosphere and held inside it. So the problem is, that the atmosphere is continuing to consist of more and more carbon dioxide and greenhouse gasses due to human kind. And therefore making the radiation from the sun become trapped on Earth in which heats up the planet. Since the beginning of the industrial revolution, nitrous oxide, which is used in fertilizer, has increased 18%, carbon dioxide from fossil fuel combustion 39%, and methane 148%. By adding more greenhouse gasses, we have altered the natural cycle of the atmosphere making it harder for radiation to escape to outer space. Gasses in the atmosphere absorb both shortwave solar radiation and low wave infrared radiation in which this radiant energy warms the atmosphere. When too much carbon dioxide is put up into the atmosphere, that disrupts the balance. Like super saturating and already existing solution. For example, carbon dioxide already makes up 0.03% of the atmosphere in which is steadily increasing. If you put sugar into water, there is a limit to which the sugar and water will no longer mix. The same happens here, if you put too much carbon dioxide up it absorbs infrared radiation depending on its vibration of its bonds. We’ll overall increase the amount of energy, and we’ll ultimately increase the overall temperature. Part of this is due to the kinetic molecular theory. Meaning more energy causes further vibration, which causes the gasses to start bouncing off of each other more quickly. Basically, the overall understanding is that there is a rise in 0.5 degrees to 1 degrees centigrade. The quantity insists of aerosols and molecules in the atmosphere affect the way that they scatter radiation. This differences is easy to observe in the visible part of the spectrum. Our sky appears blue, because the white sunlight coming towards the Earth is scattered by the nitrogen and oxygen molecules in the atmosphere. This process is called the rayleigh scattering effect. The molecules of these gasses interfere with incoming sunlight. The shortwave length, blue light, is more strongly affected and is scattered in all directions. While the longer wave length, green and red light, is able to pass straight through. As you look at the sky, you are seeing the scattered light. Therefore the sky looks blue. So if the atmosphere scatters more blue light than red light, then you may wonder why sunsets look red. First, when you look at the sunset, you are looking toward the sun, not away from it. So while all of the blue light has been scattered away, you’re looking at the redder light that passes straight through the atmosphere to your eyes. Secondly, the sun is lower than the sky, so the light is forced to travel through much more of the atmosphere. In the process, it also passes through much more water vapor and dust. Water vapor and dust both absorb the shortwave length, blue light, while allowing the longer wave length, red light, to pass straight through to your eyes. Different molecules absorb different wave lengths of light making a unique pattern in the spectrum like a fingerprint that we can use to identify the molecules. As mentioned before, one of the largest and most detrimental factors of global warming is the increased melting of permanent ice sheets and glaciers all over the globe. From 1978 to 2004, perennial sea ice cover in the arctic declined by 7.8% each decade. If these trends continue, late summer sea ice could disappear from the arctic as early as 2030. Palio climate scientists can learn a lot about the Earths past climate by looking by looking at the air in the ice. All by analyzing what geochemical proxies that are contained in the air bubbles of the ice To analyze this ice, scientists set the ice cores onto a continuous melter which is just like a hotplate, and it melts the ice core layer after layer. As the water is produced, and the included air bubbles are released it is brought through various instruments. Such as a mass spectrometer for an analysis of the chemical composition of the water and the air included. These scientists are specifically looking for properties of the water or air that can reveal what the environment was like when the snow fell on the ice sheet they are probing. This record makes the conclusion that the last 100 years of manmade atmospheric alterations have had a profound affect on the average temperature of the Earths atmosphere evident. In the ice cores there are little bubbles. And those individual bubbles contain a real sample of the atmosphere through time. Scientists can then release that air and measure the greenhouse gasses. It is almost like taking the DNA of the atmosphere. This record of past climate generated by ice core analysis is essential to the global warming discussion. It creates a benchmark for the pattern of natural variability in the climate record. And thereby, proves the existence of the manmade enhanced greenhouse effect. As palio climate scientists are struggling to record as much as they can from the ancient ice they are quickly disappearing. Nearly all icecaps and glaciers in the world have experienced a net loss of volume every year for decades. Sight light and photographic records show this in great detail. One of the places where this is most evident is in the arctic ocean where the arctics sea ice extent is declining dramatically every summer. Snow nearly accesses a mirror reflecting the sailor radiation back in the space, but when the ice is gone and the sailor radiation hits liquid water instead then, most of the energy is absorbed by the ocean, and the ocean heats up. This intern then prevents sea ice from forming and therefore by reenforces the warming trend. Everywhere the ice grows and then every summer the ice would drops. But in recent years, summer melting has brought the ice much further back than scientists have ever seen before. In September of 2012, the arctic sea ice shrank to its lowest extent ever measured. Loss of arctic sea ice is profoundly important for the globe, for a number of reasons. First of all, it has a great affect on global weather. We have an ocean that used to be covered with a solid surface that is now depleting. This affects the position of the jet stream, which now extends further north and further south. Causing blocking patterns to form which increase periods of extreme heat and extreme cold. It also affects storm tracks, like super storm sand. The arctic has massive stores of methane in the permafrost and on the arctic seabed. As we lose the sea ice we have more heat going into the ocean, that heat will be transported, causing more permafrost thawing, and destabilization of the seabed. These processes will increase the overall release of this methane which will ultimately contribute to the enhancement of the greenhouse effect and cause a spike in temperature. The effects of the polar icecaps melting will also have a significant affect on the chemistry of the ocean. More specifically, the composition of the water and the effects it has on living animals. In the past 20 years, overall land and ocean temperature averages has risen by 1.5 degrees Fahrenheit. Animals most at risk are those who live in the arctic, especially polar bears. Since a lot of the ice that they live on has melted. They face horrid challenges, some of them having to swim for hundreds of miles in hopeless attepmts to find solid ice. Many are unsuccessful in drowns from exhaustion. It is probably a process that will happen too quickly for the polar bears to be able to adjust. Ergo, we are causing their extension. We chose to research global warming because we thought it was interesting to learn about the effects we as humans have on the planet and we can perhaps learn to control our increasing need for energy and possibly shift our use of fossil fuels to more sustainable sources of energy in order to negate global warming. It is however becoming ever clearer that global warming is changing the planet at an ever increasing pace. And if we ignore the causes, it will be a very different planet that our decedents will inherent.

    im siting this vid for a presentation for my whole middle school im giving u credit btw its a great documentary

  • Zemin Bee

    Hey Emily. this is a fantastic video. Can i ask your permission to add subtitle to this video and use this for our enviroment protection project?

  • krackerToo

    Global Warming is a F..king LIE You poor stupid liberals aka F..king MORONS…Watch Cowtopia produced by the same baby killing Gay loving trash that all of you are.

  • Reversible is Possible

    https://www.youtube.com/watch?v=w2EQ6YJef6w

    this is a demo short movie about an invention that could be a little solution for themal pollution and global waming, is a fully reversible window lockable in two directions /verses, in this way you decide to reflect or absorb the light using less heaters and airconditioners to keep the comfort saving energy reducing thermal pollution and global warming

  • Dawn Paolo Abes

    is this video the original cut?
    your video has sections cut out off it which i think has so much importance

    like the part where the methane's VERY VERY high percentage contribution to EGHG was de-emphasized (was this on purpose?) and other portions which i see noticeable bad cuts

  • Zahara Ambreen

    May Allah's peace and blessings be upon you.Thankyou for your beautifully complied research.The speakers spoke in peaceful and clear voices eaisly understandable for middle school students.Your video made understanding the global warming issue very easy.

  • JOHN ERNEST LEE

    there`s a live video for global warming . the video`s is whole earth , the red is warning 3 ,the yellow is warning 2 ,the white is stable , that am i right ? i think for disaster`s only , . i think that`s live video is gone ,.

    We pump out millions of gallons of oil daily from beneath the surface of the earth. The core of the earth is molten. The reason the oil lies beneath sand of the middle East, and Texas, is to protect that barren area from overheating. The oil is a heat dispersing buffer protecting the barren landscape form the molten temperatures at the earth's core. The oil is beneath the sea, to keep the sea from overheating. We pump that oil also. Another abundance of oil is pumped from beneath ice. Once again, the oil is there to protect the ice from melting, as it is now doing. That's why temperature's are rising around the world. Global warming is real, and caused by pumping the protective oil out of the earth. What is the purpose of oil in your car? To keep the engine from burning up. Simple.

  • Castiel Anne

    Actually with today's intelligence and technology, we can create a new way to produce oil or replace oil. But we were suppressed by a high power ( the one with oil money) because they depend on oil money and everything relative. Care to debate?

  • paul somerville

    global warming is not just caused by greenhouse gasses we are using more oxygen than our nature can replace here is an experiment look at the sun rising at the north or south pole it is a lot duller than if you look at it rising from the equator that is because more oxygen is absorbing the radiation believe it or not there are ways we can address this imbalance I can show u how to do it

  • Shen Beltran

    Hey! Nice video you have there! If you dont mind my sharing; have you used the services from " Vidadsmedia Email Tools " (try googling it)? My sister had some dealings with them and was impressed by their amazing knowledge on email tools!

  • de-jane niles

    This is just what the globalist pay the crooked scientists to cook up.
    How about asking the question on the poison they are spraying in the skies through aerosol chemtrailing. Stop this cooked up crap! They're the ones putting radioactive particles into the air we breath. Look up Agenda 21.
    No it's not a dream, wake up this is real evil stuff, planned by corrupted journalist, scientists, lawyers and govt who can be bought and paid for. Look into the agendas of this global warming, It's total control of what everyone on planet earth is doing- Wake Up!

  • Dzezik 23

    WOW, this is a rocket science video for prescoolers or kids from primary scool or it is a film for average adult Americans. The Global Warming is simplified here. There is no evidence of Global Warming in this video and the proces in real is completely different. You cant simplify so much. You have no idea how Earths atmosphere works.

  • Benevolent Protector

    I guess the government forgets about those us us who remember the research teams from most every country who have been collecting historical atmospheric data from 1000,s  of ice core samples taken from Earths polar caps for decades.  Just like the rings of a tree, the atmospheric particulates that stratify in layers in these ice cores tells researchers Earths atmospheric history that dates back as far as 250,000 yrs ago.  The cores are cataloged, dated, sliced then analyzed in a mass spectrometer which then generates a spectrograph that defines the stratified base elements and compounds, then quantifies the percentage (ppm) of materials detected in the samples.  Scientists compile the statistical data in chronographical order to generate graphs used to compare past atmospheric conditions to present day atmospheric conditions.  Its from this process that I say that the information presented from the bogas government agenda on "global warming"  is nothing more than but pure BS.    The historical record from these comparisons clearly shows that over the last 100,000 years, there have been many periods in Earths history where Co2 and methane levels in Earths atmosphere have far exceeded current levels generated during the modern industrial age  (1900-2017)..and were far greater then levels reported by MSM/corporate media as being a major planatary crisis.

    I am an English teacher and not only do I find your presentation clear, professional and interesting but spoken at a  speed suitable for non-native speakers. I will be using it in my class without reserve. A big thank you!

  • we see the ligh

    I came up with an idea some years ago – making plywood from recyclable leaves thus saving many trees. I made a small prototype and it is possible and simple to do. Unable to get a patent and with no more money to invest – I offer this idea to any one interested. saving our plant one idea at a time is far more important than commercial greed.

    Anthropogenic global warming….if only it were so. Global warming would move the limit of the grain belt way up into Canada and Siberia.  Greater CO2 would dramatically increase crop yields. Hunger would cease globally. CO2 levels were many times greater in ancient times, yet no Armageddon occurred. Read the scientific papers of Dr. Heinz Hug to understand how CO2 functions in the atmosphere. It has very narrow bands of absorption, 1, 2.7, 4.3, 15 micrometers are the generalized spectral peaks. These  are ALL absorbed to extinction within 30 feet ( 10 meters) of the ground. ADDING MORE CO2 DOES NOT INCREASE ENERGY ABSORPTION, but only reduces the distance needed for full absorption by a foot or two. In fact  high CO2 levels caused  higher O2 levels (photosynthesis) that  allowed the dinosaurs to exist. (Commercial green houses inject CO2 to increase plant yields). As an example, during the Cretaceous period, there was NO ice at all at the poles, much higher CO2, and  the Earth was full of vegetation and dinosaurs. They could not live today as the O2 levels are too low for such large animals. The oceans are rising today because the Wisconsinin ice age has not yet finished, there is still ice at the poles. The ice age ends when all the ice is gone. So technically were are still in the last ice age, but the next ice age will begin before the last has ended. The climate changes we have seen in the geologic record are entirely disconnected from the CO2 levels. CO2 is a VERY minor gas in the atmosphere of Earth. Note than water vapor is a vastly  more important greenhouse gas than CO2. The reason for climate change is entirely due to the output of the sun and the amount of cosmic rays striking the atmosphere. Watch the You Tube video "Svensmark: the cloud mystery" and maybe read his book "The chilling stars" to understand the reasons for climate change,  it has NOTHING to do with CO2. After doing these things,  look on the US Geologic Survey website and find the graphs of Earth temperatures over the last 2 million years. This time period includes all the recent ice ages. You will see that this data proves we are leaving the current interglacial warm period and are entering the next ice age. In our lifetimes we will be within the next ice age. The fraud of anthropogenic global warming exists because the globalists are subsidizing it to convince us to accept a global carbon tax, that is to get western nations to accept it. There is no call for China, the greatest producer of CO2 in history, to pay such a tax. ONLY the west. This tax will in effect take money from poor people in rich countries and give it to rich people in poor countries. These globalists know of the coming ice age. Who is paying to build their subterranean survival cities so they and their families and allies can re populate the Earth after the coming ice age ends? Why, YOU and ME are of course! If the climate could be changed with just the control of the CO2 levels in the atmosphere, we could easily control the climate at will to get the temperatures we want. If only we could. Don't fall for this fraud. AGW is the greatest fraud ever thrust upon the people of the world in all of history. Don't buy it, educate yourself instead.  As a final note, read about the Vostok ice core samples, and other following sample sets to see that ice ages are preceded by a brief warming period. We are in that stage now.

    I am shocked that you have purposely left out nuclear explosions and volcanic explosions as Major contributors to global warming.

    IN THE FUTURE CLIMATE CATASTROPHES WILL HAVE AFFECTED LIVES OF BILLIONS AND BILLIONS OF ORGANISMS NOT ONLY HUMANS, CHILDREN OF CEO'S MUST PAY THE PRICE OF DEATH FOR THEIR PARENTS GREED-FUELED PULSE-LESS CRIMES.
    Its fine if some people cant participate in these heinous acts that some of us have to commit. But understand this we cannot let this fly anymore. Corrupt politicians Children must be persecuted out of society, government officials must be monitored at all times, that is the cost they have to pay.
    We 99% of the brainwashed society will pay the price of global catastrophes for our ignorance.
    Hope the 1 per centers children are alive to face persecution at the highest degree.
    we will in the future have the technology to check family tree's and DNA,
    and the public will have information on their kin .
    we will have technologies that can commit the perfect crime in the future i hope all Children of Mother Nature can fight this disease.
    I am just the start of this ideology , when i grow old i believe that the next generation will persecute the True Climate Imbeciles that fucked up the ecosystem and destroyed not only our own future but the lives of other organism that we as humanity depend upon and coexist with.
    The only way we can teach criminals and deviants a lesson is to kill what treasure : humans treasure their DNA(children)
    They had no Right to destroy our lives, and did it for their own greed now they are manipulating and brainwashing the Public who entrusts them as protectors of society. Society must persecute the people who think they are all powerful and act as gods among us, teach them a unforgivable lesson.
    The only way is persecution,
    look how religion persecutes wrong doers and most of society then follows same way the punishment ideology can flourish, so no one will ever dare to think they will get away with a catastrophic greed-fueled crime

  • Patel Vidhu

    Global warming is very serious. To control it we must need to remove co2 from air. and We must reduce the usage of coal and fossil fuel.

  • Francisco Lopez

    Dear Emily, a pity a good and well researched project is to be trolled by a band of ignorant people who push their cheap politics against Science. Many times during history, the apostle of science has been attacked by the forces of the beginning of the nutritional chain. Still, we manage to evolve and progress and enjoy the fruits of knowledge. Will share your project.

    To the People of Science:  Hello, those of you in America that see the problem our country mostly, is creating, that is destroying our planet, and have solutions. America, Trump, isn't going to do a damn thing about the planet. So, since you guys are so smart, you can see that you need to move to a country that is going to do something about it. Myself, i'm trying to get religious and political asylum in Russia and perhaps start a Sanctuary of Sophos School of Spirituality and Science if they don't mind. Their President is Intelligent. He has his country as his motivating factor. The opposite of what we have here – a larcenous, egotistical, dysfunctional, alcoholic, coke clown who kills for entertainment. Anyway, so smart people do smart things, right? Scientists. That's what I would do if I wanted to create a new world instead of bowing down to evil men destroying it.  Especially if I still had a Conscience and Soul, and Belief in Humanity's abilities to rise above whatever dilemma is thrown at them.                 I was going to wish Mr. Putin a happy Father's Day, and getting you American Scientists with a Soul, to consider moving to Russia, if you want your lives to have meaning, is his present. Immigration is through the Ministry of Interior. If you know any caring Scientists with ideas of how to build a new world that does not pollute and recycles everything, like the Native Americans and other Aboriginals, but perhaps more modern, then tell them, this is the time to do it. Create efficient, clean, living instead of standard, stupid, living needs. Grow crops on virgin soil. If enough millionaires wake up and see that this is the only way to survive, we could build that which lasts, beginning perhaps on some of that vast wilderness they have there in Russia. I don't know about dispersing a bunch of Americans throughout the population, since they hate Americans so, and Americans are so stupid when it comes to being a nice, good, human being to others. So Americans should start out together, and become better human beings and show what we can do to improve conditions in Russia. With building, comes jobs. They need good jobs there. I was thinking one of those magnetic-run railways for transportation would be nice for Russia, and employ many people. You millionaires would see a profit, i'm sure. At some point. So, if any Scientist sees this post, please share it with others. The Times, they are a changin'.  It's time to start thinking of the Future, and doing something about it now. Before we can't. And you know, a good mind is a shame to waste. But, if you're a scientist just looking to make money, stay home. We don't need that kind of scientist. With Love, the Dove

    Very beautifully explained!! But efforts taken by some human disliked by some other human… US president move out of Paris agreement.. It's really bad…

    It has been revealed that just 100 corporations are actually causing the majority of the
    world’s global warming. In just under 30 years, these companies have released
    nearly one trillion tonnes of greenhouse gases. And this evidence shows
    the narrative surrounding citizens’ own ‘carbon footprint’ and
    individual responsibility toward climate change as little more than just
    hot air.

    The CDP (formerly the Carbon Disclosure Project) has published research
    into industrial greenhouse gas (GHG) emissions since 1988; the year
    climate change was officially recognised. And it has found that 71% of
    all GHG emissions since then have been produced by just 100 companies.
    The breakdown of ownership of these companies is:
    41 public investor-owned companies (those that are traded on stock markets).16 private investor-owned companies (those that have non-traded majority shareholders).36 state-owned companies (government-owned).Seven state producers.

    Private corporations including Total, BP, Shell, ExxonMobil and
    Chevron were among those with the highest levels of emission. As were
    state-owned companies like Saudi Aramco, Russia’s Gazprom, National
    Iranian Oil, Coal India, Mexico’s Pemex, and China’s CNPC and Chinese
    Coal.
    The CDP says that: “All fossil fuel company operations and products worldwide have
    released more emissions in the last 28 years than in the 237 years
    previously”. It also reveals that these 100 companies have produced 52%
    of GHG emissions since the Industrial Revolution. This equates to nearly
    one trillion tonnes of GHG. It also says that:
    If the trend in fossil fuel extraction continues over the
    next 28 years as it has over the last 28, global average temperatures
    would be on course to rise by 4ºC by the end of the century – likely to
    entail substantial species extinction and large food scarcity risks
    worldwide.

     A wider sample [pdf p5] found that, in 2015 alone, 224 companies produced 72% of all GHG
    emissions. But the CPD report also highlights some flaws in the
    reporting requirements of companies.
    The report [pdf p5/6] breaks emissions down into ‘Scope One’ and ‘Scope Three’ types. Scope
    One is emissions from production, which companies generally have figures
    on. But the data which companies don’t know, and therefore the CDP had
    to estimate, cover the amount of Scope Three emissions. They are the GHG
    amounts produced after products are sold. This lack of data could be
    because, if consumers actually knew just how much damage products were
    causing, they might not buy them at all.

     But it is, paradoxically, consumers who are told that they have to reduce their GHG emissions. And here lies the problem.
    Consumers are constantly being reminded
    about their carbon footprint: being encouraged to drive less, to use
    less energy, and having to pay for carrier bags. All despite the
    evidence that it is just a handful of companies responsible for the bulk
    of this pollution.

     The narrative peddled by corporations, governments and institutes is
    one of ‘individual responsibility’. The public is told that stopping
    climate change is down to all of us. But this shifting of responsibility
    permits corporations to continue with irresponsible practices that
    endanger the planet, all to protect their profits. This is a practice
    not necessarily exclusive to climate change. But it’s seen whenever
    there’s profit to be made.

     For instance, ‘bed blockers’, immigrants, and missed appointments are
    often used as scapegoats for the pressure on NHS services. In turn,
    this distracts from the chronic underfunding of the health service to further its privatisation.
    Likewise, bemoaning fly-tipping on council estates distracts from
    acknowledgement that public refuse collection services have been slashed and handed over to private providers.
    In her book This Changes Everything: Capitalism vs The Climate, author and activist Naomi Klein says:
    I think the answer is far more simple than many have led
    us to believe: we have not done the things that are necessary to lower
    emissions because those things fundamentally conflict with deregulated
    capitalism, the reigning ideology for the entire period we have been
    struggling to find a way out of this crisis. We are stuck because the
    actions that would give us the best chance of averting catastrophe—and
    would benefit the vast majority—are extremely threatening to an elite
    minority that has a stranglehold over our economy, our political
    process, and most of our major media outlets.

     It is our corporatist system of governance that is really destroying
    the planet. It may make you feel better to pay 5p for carrier bags, to
    walk instead of driving to the shop, or to turn off the light that
    doesn’t need to be on. But in reality, these small adjustments don’t
    make much difference when it comes to climate change. Not when
    corporatism remains our global political system.

    Controlling global warming shouldn’t be hard. Here’s how:
    First of all, let’s look at the equations for ozone layer depletions:
    CF2Cl2+sunlight —-> Cl’ (Nascent) + ‘CClF2 (Nascent)
    These nascent chemicals are highly reactive.
    Therefore, ‘Cl + O3 —-> ClO +O2
    Now, ClO+O —-> ‘Cl+O2
    Now, this nascent ‘Cl again causes the chain reactions thereby depleting our ozone layer.
    What if we do similar thing to CO2 depletion? It goes like this:
    Suppose we have compound XY which does the following reactions:
    XY+ Sunlight —-> X’ + Y’
    X’ + CO2 —-> XO + C
    XO + O —-> ‘X + O2
    Now, all scientists need to do is find this compound XY. If I was a chemist, maybe, I would do it. But I am an Electrical Engineer. So I leave this task for chemists. 🙂

    Very well done…BRAVO! You should be very proud of yourself! One of the best, most concise and easy to understand presentation explaining climate change!

  • hermanwahsletn

    Nice presentation. However, the climate will now be colder due to less sunspots. Henrik Svenskark published a report 2017.12.19. It explains ”The increased ionization supports growth of aerosols into cloud condensation nuclei”. Since a lot of politics and money is involved in the ”global warming” this knoledge will NOT be presented in media for many years to come. Yes, when it´s getting colder!

  • Ako

    Global warming occurs during solar maximum
    Global cooling occurs during solar minimum (ice age)
    The science behind al gore's global warming is called bribery, cherry picking, and hiding other facts for example…temperature always rises first before carbon dioxide rises.

    The earth periodically heats up, the polar ice caps melt, the seas rise and flood large coastal and even inland areas. These are all well known geological facts. This period of temperature rise began over 8000 years ago when the last ice age ended it will end and the cycle will start over again, as it has many times before, man even walked the earth. The only difference in this climate cycle is the industrial revolution, it is bound to have some effect on it. One would suspect it will speed up the cycle. I have seen no proven models that can show us exactly how much effect it will have only some that show it is having an effect. Now politics and money raise their ugly heads and there is nothing but confusion and anger.

    Time for Emily to reconsider. Emily put her faith in scientists who went out of their way to prove that global warming was caused by man. Not true. The sun has controlled or indirectly controlled earth's climate. The sensitivity of CO2 has been drastically exaggerated and this sensitivity has been used in the models which resulted a much higher predicted increase . The scientists who have produced this false effect are either dishonest or not to bright and greedy. The Modern Solar Maximum is over. The Eddy Grand Solar Minimum began a few years ago and we are now seeing the changes in climate. The colder longer winters experienced in the North East, Europe and Australia are symptoms of the change towards a cold era. Interestingly, Alaska has seen a more warming trend which also occurred during the Maunder Minimum. The Arctic Ice sheet is thicker than it has been in years. Global Temperature is on the down swing and it is cooler now than when Gore got the peace prize and he is also richer. Solar Cycle 24 has been the weakest since the Dalton Minimum. Cycle 25 is predicted to be even less active. One additional thing that occurs when the sun is at a low is it's magnetic field collapses allowing more cosmic rays to bombard the earth. They in turn create rain nuclei which causes more cloud coverage and reduces the sun light that gets to earth. Volcano and earth quake activity statistically have been known to increase at solar minimum. Volcanoes and increase in cloud cover are two of the forcings that will drop earth's temperature. Most of the scientists who study climate and are predicting a cold era do not admit that we are leaving the inter-glacial period and are falling into another ice age, but all the signs add up to just that. I'm afraid that man is entering an apocalyptic time. Much suffering is going to happen over the next hundred years and a decade from now all the people will know that Global Warming was a big fat lie setting us up to fail the climate challenge. Emily, don't you now feel that you were conned by main stream media, the UN, Al Gore, Bill Nye, Neil DeGras Tyson? You should just have graduated from college. Have you chosen a scientific field of endeavor? Your video was sincere and convincing, but unfortunately based on bum data which makes it propaganda. May be you can help fix the problem of this impending cold era.

    Those who do not believe that global warming is automatically amplified by increased carbon dioxide emissions must first logically assume that the greenhouse effect is not real. Thus, by extension, there’d be no such thing as Greenhouse Gases. Also, they do not yet understand that all life on Earth has always depended on the Greenhouse Effect for survival, because without it being real the globe would look like a snowball.

    However, if they were to search online-> ‘demonstration proof greenhouse effect is real’, then they would see for themselves that the greenhouse effect is demonstrable and that, indeed, carbon dioxide is a “greenhouse gas”. Hence, the impact that carbon dioxide has upon the greenhouse effect.

    Note: The above experiments do not show the ratio of warming per unit of CO2. Such finesse in a jar is not possible. The intent is only to demonstrate that CO2 absorbs warmth:

    The Dynamic Role Of Greenhouse Gases & how quantum mechanics explains global warming (5 minutes):
    https://youtu.be/-EJOO3xAjTk
    As the sun emits the full spectrum of electromagnetic energy, the Earth absorbs both longer waved infrared light (IR) and shorter waved visible light. The total of this absorbed energy causes thermal heating that is gradually re-emitted in the form of infrared energy. Much of this is reabsorbed by the larger molecules in the atmosphere such as carbon dioxide and water vapor, but not the smaller molecules such as nitrogen and oxygen. This creates a positive feedback loop between the atmosphere and the Earth’s surface and causes temperatures to rise. Thus, more heat is retained than escapes back into space.
    Note: Any increase of larger molecules in the atmosphere raises its thermal level and is a function of both classic physics and quantum mechanics.

    In 1999 the government and people say "we will all die in 2000" yet here we are in 2019. i believe in god i know god is doing this. don't blame us. god is doing for it is his earth and he has all rights. so don't go around saying "humans are a problem". without humans and oil and gas and coal would we live? its common sense. If the earth ends thats god's decision not because of the earth exploding. who made the earth? who made humans? who made the "big bang theory"? who made the universe? who created the milky way? GOD he did it thats who. so we are not to be blamed for this. and iam not saying god is doing wrong iam saying smarten up. and who are you to even dare say that what would happen in 200,000,000 years for you do not assure you will live another second.

    You made a very good explanation. However, the problem is that Global Warming is made up by corrupted politicians. Not discovered by science. And for the polar bears: There number has risen from (about) 7000 in 1960 till almost 30000 present. Which has nothing to do with the quantity of ice but with animal protection.
    Further more, the is no rise of temperature or loss of ice in the past 20 years. The real problems of humanity are our number, at present 7,7 billion increasing by 80 million each year, and desertification due to agriculture.

    An unfortunate mix of incomplete facts (principles) and inappropriate conclusions. When you add the numbers, the amounts and physical constants, the natural laws and especially the historical numbers all the conclusions become invalid. Most people are not aware that the effects claimed for CO2 are to this day purely speculative. There is no actual experimental proof of the claimed role of CO2. Short term coincidence is being treated as long term causation. Global warming cannot release the methane clathrates. If it could they would have been released during previous much warmer warm periods. Methane oxidizes to CO2 quickly anyway. This presentation completely ignores the experimentally proven role of solar and geophysical entities in controlling planetary warming and cooling, which are the real cause of climate fluctuations. Statistically weather extremes have not changed. Notice the use of "within the memory of living people"…. That way older data which contradicts the claim can be omitted without lying. As a propaganda piece this is well done and it is sad that children are sucking it up. They are not getting the real facts and data.
