  • Part 2

    Prof Judith Curry argued it is becoming evident that factors other than CO2 play an important role in rising or falling warmth, such as the 60-year water temperature cycles in the Pacific and Atlantic oceans When both oceans were cold in the past, such as from 1940 to 1970 the climate cooled The Pacific cycle ‘flipped’ back from warm to cold mode in 2008 and the Atlantic is also thought likely to flip in the next few years

    AMAZING

  • @Texmurphy51 You are so right. To anybody reading this, read the comments below. Nothing is one sided.

  • Part 1

    Based on readings from more than 30,000 measuring stations, the data was issued last week without fanfare by the Met Office and the University of East Anglia Climatic Research Unit. It confirms that the rising trend in world temperatures ended in 1997

    The Met Office climate models show there should have been ‘steady warming from 2000 until now’

    Continued

  • Biology is powered by plants metabolising carbon dioxide

  • The world has been cooling naturally for for teen years. Photosynthesis has metabolised all ecoshere carbon dioxide from the air to form new life on earth

  • Biology does nuclear fusion

  • Green plants metabolise all the available carbon dioxide. And the global climate has been cooling since 1998.

  • The biggest worry of the early 21st century is a nuclear power are somehow get new plants of death constructed. They are overpriced, fatal and toxic.

  • The world has been cooling for for teen years. The free carbon dioxide only rise is in ice ages when there is less photosynthesis

  • Global warming was fiction from nuclear power after Chernobyl

  • Biology teaches that photosynthesis converts all available carbon dioxide into new life on earth. Harvard University has confirmed after two years server in 2010 average carbon dioxide levels have not risen since the industrial revolution

  • @JonThm so everything is going perfectly then? no worries?

  • Photosynthesis is adaptive and dynamic: as man releases more carbon dioxide there are more plants to take this gas in. So carbon dioxide levels are still at home free industrial 2ppm-as predicted by high school biology!

  • According to Harvard University the carbon dioxide level in the countryside, the vast bulk of land area on the earth, has remained static since it fell at the end of last ice age

  • Harvard University put on record August 2010 that there have been no increase in average global carbon dioxide due to man. ever. Plants have used all the carbon dioxide to do more photosynthesis. That is high school biology

  • @JonThm plants have used the extra carbon dioxide for photosynthesis. Man has never increased the Irish level of carbon dioxide in the global air

  • The world has been cooling for for teen years now

  • Because of photosynthesis man can never increased the level of carbon dioxide in the air

  • @JonThm And we are deforesting large areas thus limiting the planet's CO2 buffering capacity.

  • @JonThm Also we are emitting too much to be regulated, plants can only take in a certain amout of CO2. If You pour more water into a bathtub faster than it can be drained than it will not drain.

  • @JonThm Also you say that we can never increase the CO2 level, we have been for almost a Century.

  • @Paratrooper12100 plants have converted all man is carbon dioxide into extra life on earth

  • @Paratrooper12100 grass sinks more carbon dioxide Manchester. There are massive excess of photosynthetic organisms on earth/go get educated

  • @JonThm Apparently not, the atmospheric CO2 ppm would not keep rising if that was true, as the permafrost is thawing on the northern hemisphere yes there are improving conditions for new flora to grow and suck up more CO2 but massive amounts of methane is released in the process as well which is a much more potent greenhouse gas than CO2 (25 times better at trapping heat than CO2).

  • This is nothing but misinformation

    Plenty things could happen

    I could win the lotto, i never do

    Thinking i could win the lotto should i spend the money now?

    Well i could win the lotto so shouldn't i count on it happening? Of course not!!!

    None of this is based on proven science.

    It is all hypothetical.

    Since when do we make disicions based on hypothetical scenarios.

    We are better and smarter than this!

    We need to look at the people who claim these things, and why they are claiming them.

  • Free carbon dioxide can only rise in an ice age: you do photosynthesis metabolising this gas

  • The fossil fuels formed from as 65% of life which died with the dinosaurs

  • The Jurassic have more life on earth and lower sea levels than today. When all the organic carbon was circulating as carbon dioxide

  • Good Video, Thanks for shared.. Good..

  • Photosynthesis metabolises carbon dioxide

  • Photosynthesis metabolises carbon dioxide

  • Drill baby drill

  • Plants take in carbon dioxide to do photosynthesis. No more carbon dioxide in the air today air than two centuries ago air

  • Fossil fuels formed from life which died with the dinosaurs at the end of the Jurassic

  • Hi I'm 11 yrs old. Does this means that there will be the end of the world due to global warming?

  • Plants take in all the available carbon dioxide to do photosynthesis. Carbon dioxide supports all life on earth including yours

  • Photosynthesis metabolises all the carbon dioxide from the air. To support new life on earth. No effect on the weather is possible. Are you stupid of what?

  • Biology metabolises carbon dioxide

  • The world has been cooling for 13 years-totally naturally!

  • More evidence/impacts of climate change series...(please read article before the denier censors it)..

    .

    Antarctic worms to provide clues on climate change in oceans

    .

    A study by the National Science Foundation focuses not only on how the polar worm Capitella perarmata adapts to the frigid waters and survives temperature changes, but also on how it adapts compared with a close relative, the Capitella teleta, that inhabits temperate waters.

    21 December 2011

  • Man could not increased the level of carbon dioxide in the air if he tried! Never heard of photosynthesis?

  • "Not so fast sunbeam - you ain't going nowhere!"

  • Plants have converted man is carbon emissions are into extra life on earth. No more carbon dioxide in the air.

  • Green plants have produced a static level of carbon dioxide in the air for last 200 years

  • The world has been cooling for 13 years

  • Great! so the scientists are saying that, quote "man made or not" bad situation we face blah blah blah!

    So everyone give up your jobs to the chinks, threw our standard of living to the wind, because some assholes are scared of the future, if its the time that the planet wants rid of the humans then it will let us know real quick and theirs not much we can do about it. whether you have an electric car or a god given V8 you will be gone, fuck all you can do about it. So YOU give your jobs up!

  • Sheffield University can do nuclear fusion.  Power with no carbon dioxide.

  • POP QUIZ: How many Earths would it take to feed the world the way Americans eat?

    The answer will be posted in the "Comments" section of my channels home page.

  • crap trap more bullshit

  • @vmgqie The expression is "claptrap". Why is it so few deniers can spell, write properly, get their euphemisms right, or be bothered to know any real science? Do you really think a brief text response adds something to the argument that it previously lacked? Here's another fact: a poll taken around the time this video came out showed that more people trusted their local weatherman's dubious opinion on global warming than they trusted climatologists saying it exists. Now that's a successful scam!

  • @GeorgeDRange i now what i meant its crap and its a trap because we are caring human beings and were concerned about future generations and there welfare we believed in what these scientists were saying little did we know they are frauds, lyres, bullshit artists that's the trap we believed in it but now i know better so fuck you dickhead

  • @vmgqie Let me see if I've got this straight: It's a trap to be cautious, and it's conservative to throw all caution to the wind, for the sake of the future generations. Because they deserve worse behavior, not better. Too bad your grandchildren will never see a Black Rhino, (gone) or glaciers in the Alps (going) or on Kilimanjaro (also gone). Huh. Guess that means you're having no impact at all, either way.

  • @GeorgeDRange what a load of incoherent drivel you spout in Australia we are going ahead with carbon tax that's not going to change co2 output but i will tell you what it will change my job that goes in the shit bin thanks very much. so what now how do i pay my bills which are going throw the roof and feed my four kids all this talk mmgw really piss me off, if, it might or one of my fav in 100 years i don't give a shit about a hundred years what do i tell my kids tomorrow when there hungry

  • @vmgqie First of all, sorry to hear about the job, it would seem that things are tough all over right now. Understand that regardless of how strongly I may disagree with people, I do put people first in my personal life, and would never actually wish you any ill. Hopefully something becomes available to a skilled individual such as yourself. No replacement for skill and experience! As for my argument, I'm only saying that time will tell, and BTW, if I'm wrong you also get your job back, right?

  • @GeorgeDRange don't worry i will get a new job its that environmentalists and global warming alarmists say that carbon should be reduced well when reducing carbon it usual means some poor bastard losing his job that he's done for twenty years and that's all he knows it can be very depressing and soul destroying and especial when i think the science isn't settled and not properly debated without emotion just hard facts

  • @vmgqie Right on, hope things get better for us all! Ecology aside, the economy kind of bites everywhere these days! One thing to consider: If the hard evidence does suggests that it is happening, (man-made on not) there will certainly be a lot of engineering work to go around! Nobody can deny that we are a resourceful species that doesn't have to wait around to mutate and adapt! We can simply decide to be more adaptable! Take care!

  • @vmgqie Here's to me being wrong about warming trends. I absolutely hope I am wrong, and will very gladly give great thanks and apologies (PUBLICLY) if I am. In video log form, right on this very channel. But the problem is, I was a university kid, raised by a college professor, and I know a lot of scientist. I knew the man who discovered the atmosphere of Venus was poisonous by using spectral analysis. And the consensus seems to be that it's a bad situation we face, man made or no.

  • comments should only be allowed for those who have taken a thermodynamics class.

  • find out for your self and look up what is really happening ...

    the earths magnetic feild was designed to keep deadly radiation out of our biosphere....

    you figure it out

  • who is going issue and sell carbon the credits. its a scam !!!!!

  • No rise in global free carbon dioxide for two centuries due to photosynthesis

  • I blame Bieber fever for the increase in heat

  • I have heard that the SUN is responsible for heating the earth.

  • @MrMick73 The sun is responsible for heating the Earth, does anyone deny this? If you can find me someone who does this, then they're dumber than a global warming denier.

  • @MrMick73 Someone had to TELL you that, huh? Really? You've heard tell, by crackey? You certainly bring a daunting scientific presence to the discussion! Perhaps it is a hoax that people's homes are sliding off their foundations in parts of the arctic circle, because the permafrost is melting beneath them. I think that bears repeating: The PERMAfrost is MELTING! It may also seem like a hoax that tons of the greenhouse gas methane is escaping from the permafrost each year, but it is true.

  • Green plants convert additional carbon dioxide into extra life on earth

  • I believe its from the under ground weapons testing that they are doin in the artic

  • @Erica06011982 see a lot of james bond?

  • @Caffineguy152 Do your reseach under ground weapons testing is a pratice by all governments anybody with common sense knows it would cause a chemical reaction.

  • @Erica06011982 yeah they know its common sense , that's why they dont do it!

  • Google under ground weapons testing

  • @Erica06011982 yeah i got government website!

  • I've notice my peanut butter and jelly sanwiches have been just slightly more slimy over the past decade. Coincidence? I think not.

  • This warming has been verified in another planets of the Solar System. Is then this warming in these planets caused by the Co2 too? Thank you.

  • How do you explain the ancient Viking settlements and farms they are finding under the receding ice in Greenland?

  • i see that the NWO has made its presence felt, however that does not change the fact that the north pole has defrosted, it doesnt change the fact that greenland is defrosting faster than ever. antarctica is next, and with it the tectonic plates around the world will be effected. this is no doom and gloom bullshit, its a real threat and one that could easily land mankind back in the stone age.

  • No rise in global carbon dioxide is possible due to world photosynthesis. The world has been telling since 1998!

  • NASA is run by blood thirsty vampiras.... those who are working for these agencies world-wide are pompous maniacs half-brain dead, they don't know what compassion and harmlessness to others stand for. They are fractaled individuals without coherence and love... associates of the Devil.

    Shame on those cursed beings as they are accumulating the lies and murders that their plans are fostering worldwide in the name of Science, Control, Power and Greed.

    NASA = NAZI science propaganda office = FAKE

  • @RastaforSai r u dumb?

  • Only Fools take NASA and other space agencies as reliable sources.

    U are being told a STORY... a freaken story for ignorant kids...

    Now tell me : IS IT WARMER WHERE U LIVE SINCE 10 YEARS?

    I live in India where average temperatures have dropped so significantly that I had to adapt my clothing drastically... I was going topless for years due to heat, now I wear T-shirts almost all year round!

    Well, with all the chemtrails of course, how could the sun ray still warm us, indeed! MANIACS!

  • Comment removed

  • The level of carbon dioxide in the global air is controlled only by photosynthesis

  • Global warming is biologically impossible. Plants metabolise all the available carbon dioxide

  • No more carbon dioxide in the air and 200 years ear. More life on earth though

  • Basic high school biology teaches that free carbon dioxide in the air is controlled exclusively five photosynthesis. Man can increase the life on earth, but can't affect the level of carbon dioxide in the air. The global climate has been cooling since 1998. The only people who believe in global warming are in the pay of nuclear power-as here

  • current CO2 levels are at 388 ppm and rising. it wont be long before antarctica begins to thaw as fast as greenland currently is, which btw is rising out of the sea at a rate of 1 inch per year. when antarctica thaws enough it too will rise out of the sea. it is connected to every tectonic plate around the world and will crack the earths crust. this isnt doomsday bull, this is science, and quite likely the worse threat facing mankind.

  • @vengencefrom1979 "it wont be long before antarctica begins to thaw as fast as greenland currently is,"

    Contrary to what deniers will say, Antarctic LAND ice is already falling in mass. Antarctic SEA ice is growing slightly, even though the measured sea temperature is rising. The rise in sea ice is believed to be linked to the ozone depletion around the southern polar area.

  • Carbon dioxide is taken in by plants as they do photosynthesis. No increase experienced on the level of carbon dioxide ever due to man

  • @JonThm NASA, NOAA, met office EEA and every national science academy on the planet disagree with you.

  • Global warming is impossible nuclear fiction. Devised to scare the stupid

  • there is a global warming or climate changed since Abraham's time...and it happen again in times of Joseph...the truth is,this is a part of american politics.

  • @kidbagsik2 You do realise scientists life in more countries than America, at times with almost completely different political systems...?

  • @ferrett78 they used this research to reduced the population of the world,which is the new world orders that been announce often times by U.S. President. watch New world order.

  • @kidbagsik2 So your claim is that the vast majority of climate scientists are falsifying results in order to push the political agenda of a single global government? And yet miraculously, in the history of this alleged organisation, not a single person has spoken up about it and not a single one of the tens of thousands of "corrupt" scientist has ever slipped up?

    That's quite a hypothesis. Any evidence?

  • Let me give you some facts:

    The atmosphere's CO2 volume IS 0.039% .

    Planet Earth is consisting of 80% water and 20% land.

    The climate temperature has decreased in the latest years

  • @ItsAllFraud "The atmosphere's CO2 volume IS 0.039% ."

    Atmospheric ozone is 1000 times less, yet it does an effective job blocking ultraviolet radiation. Why do you assume 1000 times more CO2 can't have a similar effect with infrared?

    "Planet Earth is consisting of 80% water and 20% land."

    By surface area. And?

    "The climate temperature has decreased in the latest years"

    Really? According to whom? Considering 2010 was equal warmest year for average global temperature, I find your claim doubtful.

  • @ferrett78 If it wasn't for the Greenhouse Effect no life on earth would exist. Please don't buy into this eugenic and global lie. Why do you think 30,000 scientists are suing Al Gore?

    It's joke. How can someone demonize the science of nature and call it "un-natural"?

    The enviromentalists are also now saying that the different times of the year (winter, spring, summer) are un-natural and due to global warming . Pull yourself together and do some PROPER research who isn't funded by governments

  • @ItsAllFraud "If it wasn't for the Greenhouse Effect no life on earth would exist. "

    There's a difference between the greenhouse effect due to naturally occurring CO2 and the effects of increased greenhouse effect due to mans emissions.

    "Why do you think 30,000 scientists are suing Al Gore?"

    I don't see how this effects the thousands of published papers in reputable journals that say climate change is happening. Weren't you suggesting proper research? Al Gore isn't a climate scientist.

  • @ItsAllFraud "Pull yourself together and do some PROPER research who isn't funded by governments"

    Seeing as I actually read science journals, I'd suggest that my research is far more comprehensive than your own, judging by the inaccuracy of your claims so far.

  • @ItsAllFraud

    regardless who is suing who. That does NOT influence in any way the fact that Global Warming is happening. Glaciers from where Im from in my OWN LIFETIME I have noticed shrinking! I have personal photos to back that up! We are seeing more and more unusual events happening across the globe and I do beleive this has something to do with our impact on the enviornment. To bring you back to Algore, please refer to "The Inconvenient truth" as its simply staggeringly true!

  • Global warming is gay.

    Its already 50 fucking degrees here in my country.

    And we are living just fine :)

  • Plants have ensured that carbon dioxide levels in the air have not increased for two centuries

  • i need your permission to use this video for my short movie on global warming

  • Nature does nuclear fusion from regular water

  • Carbon dioxide has been static for two centuries

  • The world has been cooling since 1998. Green plants have converted all mankind's additional carbon dioxide into extra life on earth

  • there are FOOLS all over that love to joke about this, when this is the greatest danger to us being here in the next 50 yrs

  • High school biology teaches that green plants take in all the available carbon dioxide to support life on earth. The levels of this gas in the air have been static,, by definition for 200 years. GW is lies from nuclear power and the stupid

  • The reason the earth is warming is because its a naturopathic occurance. Over thousands of years the earth has been known to increase temperatures then go into an ice age, then increase again. And now were at the end of that cycle where earth is warming and we're due for an ice age soon (in relation to the constant cycle)

  • The cooling trend has started. If climate scientist believe that human produced co2 drives our climate, they should be locked up in the nearest asylum.

  • @david222444 : Any source for your claim? you might otherwise yourself need to be locked up in the nearest asylum.

  • @nigelelsass Sorry I will try to break this gently but you are the one needing therapy. You can start your treatment by doing a simple search for Global Cooling, as a resut you will discover a whole new world of truth and not political propaganda. I hope you recover from your brainwashing soon.

  • @david222444 : Any "DATA" to support your claim?

    I have pretty much 90% of glaciers, 150 years of temp records, tree rings, coral growth, satellite temperatures, measurments of radiative forcing, etc to support mine - PS: "opinions" do not count as measurable facts - in case you didn´t know. YES WE ARE WARMING

    Note: you can recyle lies in loops - that will never make it a fact. You will not find any statistician saying we are cooling over the last 50 years

  • @david222444 "doing a simple search for Global Cooling, as a resut you will discover a whole new world of truth"

    I took your advice and did a search through Web of Science for papers with "global cooling" in the title. Seems there's only 5 pages of results, none of which suggest the globe is currently undergoing cooling. There was one I thought you might be interested in:

    Petersen, Connoley & fleck (2008) "THE MYTH OF THE 1970s GLOBAL COOLING SCIENTIFIC CONSENSUS." - BAMS 89(9).

  • @ferrett78 The70's BAMS are nothing compared to the Greenhouse BAMS. I suggest you try a little harder, maybe use a different search engine. You will get better eventually.

  • @david222444 BAMS - ie: the Bulletin of the American Meteorological Society. It's a journal. I realise these probably arent your usual source though if you suggest google is better for scientific knowledge than Web of Science.

    PS. You'll also notice that the particular journal was about the 70s, not published in the 70s. The publication date was in my citation (ie: 2008)

  • Comment removed

  • High school biology teaches that green plants metabolise all the available carbon dioxide, to form new life on earth. Man made climate change is an idea for them by the mentally defective

  • @JonThm : Have you never ever studied past high school? poor kid - tell me about your accident instead of spreading lies

  • High school biology teaches that the level of carbon dioxide in the air is controlled by photosynthesis not mankind

  • High school biology teaches that green plants take in all the available carbon dioxide. Harvard University in August new scientist but on record that there has been no increase in free carbon dioxide in the air for 200 years as a result. Did you never do biology?

  • @JonThm "Harvard University in August new scientist but on record that there has been no increase in free carbon dioxide in the air for 200 years"

    I see no such article. Perhaps you could provide a better reference?

    "High school biology teaches that green plants take in all the available carbon dioxide."

    ALL available carbon dioxide? Really? Perhaps you should leave this to people who know more about biology than your high school taught?

    Just a thought.

  • @JonThm : WRONG but that doesn´t matterr -you get your money anyway. Can you tell me about your accident? Did it alter your judgment?

  • HAIKU

    I hatch! Crawl! And swim!

    Oh how I love my sweet life,

    But—why's the sea so WARM?

  • The global level of carbon dioxide in the air has been static for 200 years due to green plants. Only local variations are possible. And they have no effect on the world weather

  • @JonThm Yup, and the earth's population has remained static for the last 200 years due to death....lol

  • @JonThm You keep saying it, but provide no citations. Have you even checked your own claims?

  • @JonThm : Crackhead! Sorry the fact you had a severe accident doesn´t give you the right to spread lies

  • The weather has been cooling since 1998. Harvard University has put on record that there global carbon dioxide level has not changed in 200 years

  • There has been no increase in carbon dioxide in the air for last 200 years due to green plants

  • @JonThm Oh? You should remind the atmosphere. It seems to be ignoring your claim.

  • @ferrett78 the natural weather is in a cooling phase. Carbon dioxide levels in the global air have been static for 200 years. Levels in cities have no bearing on the weather

  • @JonThm "Carbon dioxide levels in the global air have been static for 200 years. Levels in cities have no bearing on the weather"

    And yet the Cape Grim monitoring station in Tasmania is the first point on land that the westerly wind hits for thousands of kilometers and registers the same upward trend. The nearest decent size town (20k population) is about 100km away. It has some of the cleanest air on the planet, and the CO2 trend matches everywhere else.

  • @JonThm : You can repeat it as much as you want that doesn´t make it true ! Just google "mauna loa" or "keeling curve"

  • global warming is Bullshit

  • I wouldn't mind a change to sustainable energy, it makes plenty of sense for the long term.

    But this whole global warming trend sucks. Even if there is some grain of truth to it, it would be nice if anyone could actually present scientific evidence instead of hockeysticks, computer models, or statistics. All of these can be interpreted to match your own agenda, so what's the point?

    Let's face it, we don't know enough about the climate to draw any reasonably solid conclusions.

  • @gaboonviper1000 "Let's face it, we don't know enough about the climate to draw any reasonably solid conclusions."

    Dont mistake how much you personally know about the climate system with how much people who study it daily know about it. I personally don't know how many pharmaceuticals work exactly, but I wouldnt conclude that medical scientists therefore cant draw solid conclusions regarding their field of expertise.

  • @ferrett78 I'm basing this on the rather sketchy evidence they are using to try and convince us. Sure, they know that CO2 is a greenhouse gas. But that's where the knowledge stops, and we enter the murky field of guesswork.

    Do we throw enough in the air to affect the climate so drastically? Is CO2 even the main greenhouse gas out there? Doesn't the climate have any natural safeguards?

    I'm not a climatologist, but the lack of hard evidence and consensus on these subjects speaks volumes.

  • @gaboonviper1000 "Do we throw enough in the air to affect the climate so drastically?"

    Yes. We currently emit over 100x average volcanic emissions. Volcanic CO2 has affected temperatures in the past - no reason the same amount emitted by humans wouldnt.

    "Is CO2 even the main greenhouse gas out there?"

    No. There are many others, and much stronger ones. Even water vapour.

    "Doesn't the climate have any natural safeguards?"

    In what way?

  • @gaboonviper1000 "I'm not a climatologist, but the lack of hard evidence and consensus on these subjects speaks volumes."

    Lack of hard evidence? There's decades of science and thousands of published papers. There is a very strong scientific consensus. Practically every national science academy of every major country supports the theory. The vast majority of scientists in the relevant fields support it. Governments of many ideologies support it.

  • @ferrett78 I'm glad you have all the answers to my questions. Now if you could just point me to the evidence that would be nice.

    Published papers, scientific consensus, international support. Those are opinions, opinions are made by people, and people are idiots. Where are the double blind studies? Small scale reproducable setups?

    We emit over 100x average volcanic emissions? Someone else said the exact opposite. Who am I supposed to believe?

  • @gaboonviper1000:

    Volcanoes: around 200MtCO2/year (source USGS); Mankind: around 30,000MtCO2 (source: shell/BP/UN/IEA/EIA/OECD/etc..­.) - those who told you the contrary wanted to mislead you very clearly.

    So now - the evidence? well it gets tough and hope you AT LEAST had some spectral absorbtion physics in high school - so google "attribution-detection of climate change" - papers are (Harries, 2001), (Griggs, 2004). (Chen, 2007), (Wang, 2009), (Evans, 2006) - good tough reading!

  • @gaboonviper1000 : Here is by the way the radiative forcing of man-made GHG by the national oceaning and atmospheric organization: esrl.noaa.gov/gmd/aggi/

    If you want to observe the spectral absorption of CO2, here you go: /watch?v=SeYfl45X1wo

  • @gaboonviper1000 "Now if you could just point me to the evidence that would be nice."

    Try scientific journals. They are full of them. You could even try the IPCC reports. AR4 WG1 is probably what you're after.

    Again, saying there's no evidence doesn't mean there is none - it just means you havent looked.

    Just out of interest, there are very few double blind studies or experiments in astronomy too, would you suggest it is unscientific also? Obviously, some systems are too large to experiment on.

  • @gaboonviper1000 "We emit over 100x average volcanic emissions? Someone else said the exact opposite. Who am I supposed to believe?"

    There are several papers with estimates of volcanic emissions - Im fairly sure even the USGS has one. You could also look at Kerrick (2001) or Moerner and Etiope (2002). CO2 resulting from fossil fuel burning is available from the EIA. Then do the math.

    Or compare Pinatubo (Gerlach et al 1996) to human emissions that year (CDIAC).

  • @gaboonviper1000 (i) No climate does not have any natural safeguards beside "warming". The safeguard is the "natural decrease of CO2 levels" which is around 8 Gt/y (maximum) while we emitt 30 Gt/y.

    Other GHG such as water vapour play a role - however it has NO FREEWILL and just adjusts to levels of energy given by other parameters.

    Lack of hard evidence? ??? minimum arctic sea ice ever? unprecedented glacier melt? hottest decade ever? warming oceans? species migration? dude!!!

  • @nigelelsass The evidence you're talking about can have any number of causes. What makes you so sure that CO2 is the one?

  • @gaboonviper1000 : VERY GOOD QUESTION ! The warming is driven by greenhouse gases because (1.1) there is no increase in solar output over the last 40years (1.2) Warming occurs mostly in polar areas (which get the least sun) (1.3) No increase in day/night temperature difference; (1.4) The top layer of the atmosphere cooled down but the troposphere warmed (if it would have been the sun both would have warmed). => It is NOT the sun - also not volcanoes (whose emissions are small&have not increased.
