13 Misconceptions About Global Warming


Let’s talk about the science of climate change.
Don’t you mean Global Warming? How’d you get in here?
I’m the Internet, I never left. Now why’d you change the name? Global warming wasn’t
happening so you had to call it “Climate Change”? The overall average temperature of the planet
is increasing so Global Warming is technically correct, but that doesn’t mean it’s going
to be warmer everywhere all the time. And that leads to some confusion, like on
a cold winter’s day, you might say… So much for global warming!
Exactly. So the term climate change indicates that
the problem is more intense storms, droughts and floods, ocean acidification, not just
that the globe is warming. But it’s not.
What? The globe’s not warming.
Since when? 1995
Um, that’s not how you draw a trendline through data.
If the slope is nil, the climate’s chill. Y’know thirteen of the fourteen hottest years
occurred this century and the graph you’re using is old, it doesn’t include satellite
data. If you take that into a count, the trend is obviously continuing upwards.
Oh, so now you say it’s warming. In the past scientists told us it was cooling. Why can’t
they just admit that they have no idea what’s going on?
It’s true in the 1970’s there were some papers published predicting cooling, but over that
same time period there were six times as many papers predicting warming. So scientists really
haven’t changed their tune. Well just judging by temperatures, I say they’re
wrong. The Earth is cooling. But you don’t just have to go by temperatures.
There are plenty of other signs that the globe is warming, like sea levels are rising three
millimetres a year. That’s an indication that the oceans are getting warmer and so are expanding.
Ice on Antarctica and Greenland is melting at unprecedented rates and arctic sea ice
continues to decline. Nuh-uh. Arctic sea ice increased forty percent
in the last two years. That last little uptick? That’s what you focus
on? What about the general downward trend? It could mean anything. You know if the Earth
is warming the most likely source of the problem is the sun. The sun is getting brighter. Did
you ever think of that? The sun was getting brighter, in the 1930’s,
and it probably contributed to some warming then. But since the 50’s the sun has been
getting dimmer and temperatures continue to rise.
Oh, so you automatically assume it’s man-made CO2.
You know humans only emit a tiny fraction of the CO2 released into the atmosphere every
year. That’s true. People emit about 30 gigatonnes
compared with 780 gigatonnes from natural land and ocean processes.
So you admit it, humans aren’t the problem. No! Before us the system was in balance with
the land and oceans absorbing that same amount – 780 gigatonnes a year.
This balance kept the carbon dioxide levels in the atmosphere between 180 and 280 part
per million for 800,000 years. Now it’s at 400 parts per million and still rising.
But our small contribution couldn’t have caused that.
Well the amount of CO2 in the atmosphere is increasing by about fifteen gigatonnes or
two parts per million every year. But how do you know that’s man-made CO2?
Because the isotope carbon-13 is less common in fossil fuels than it is naturally in the
atmosphere. And over time we’re seeing the concentrations of carbon-13 are decreasing.
But volcanoes emit way more CO2 than humans. No they don’t. They emit about 0.25 gigatonnes
annually. That’s less than one percent as much as humans.
OK, well even if we are responsible for the rise in CO2, it doesn’t matter because water
is by far the most potent greenhouse gas. Yes it is.
I win. No you don’t!
Water in the atmosphere is increasing as well. But that can’t be due to human activity.
The only way for the atmosphere to hold more water vapour is if it gets warmer. So…
Hang on, you’re not saying… Yes! It all comes back to CO2. A doubling
of CO2 on its own would increase the temperature of the globe by one degree Celsius. But that
warming means there will be more water vapour in the atmosphere and ice will melt reducing
the reflectivity of Earth’s surface. So it’s a positive feedback loop, which a bunch of
different sources of evidence all indicate will lead to about a 3 degree Celsius rise
in temperature. But if this is true, why have all the predictions
failed. In actuality most of the predictions show remarkable agreement with observations.
But you’re probably thinking of the model from 1988, back when we thought climate sensitivity
was higher. If you re-run that model with 3 degrees of warming for every doubling of
CO2, the predictions match exactly the warming that we’ve observed.
But the Earth has warmed and cooled in the past. So who was releasing CO2 then, aliens?
We understand that past changes in the climate were triggered at regular intervals by Milankovitch
cycles, that is the periodic oscillation of the Earth’s tilt, precession of the tilt,
and stretching and squishing of Earth’s elliptical orbit.
During every warming cycle, CO2 and temperature rise together.
Ah, but if you look closely at that graph, you’ll see that CO2 lags behind the temperature
rise, so it can’t be causing the warming. The CO2 doesn’t cause the first warming. The
Milankovitch cycles change the way the sunlight hits the Earth and that causes a little bit
of warming decreasing the solubility of CO2 in the oceans. So some of that CO2 is released
and that is a positive feedback loop, which amplifies the warming. In fact over 90% of
the increase happens after the CO2 starts to rise.
Let’s say you’re right, and the CO2 we’re releasing is warming the planet. What’s so
bad about that? The planet gets a little warmer, big deal.
I’m not claiming it’s going to be some sort of crazy catastrophe, but we are going to
get more intense storms, more droughts and floods, the oceans will become more acidic,
sea levels will rise and my point is it would be better for all species on this planet and
probably cheaper for us if we just started reducing emissions now than if we wait and
pay the consequences later. No thanks.
Why are you wearing sunglasses? Global warming.

  • Can you please do a video about flat earth theory?

  • 3:03 looks very linear for some reason. Climate reform started in the 1990's and there were way more unsatisfactory practices happening in the early 50's and 40's within the industrial sectors. Despite this, the graph to me doesn't show enough correlation to the radical large-scale technological and sociopolitical trends we have achieved and pursued (as a detriment to, or in pursuit of helping climate change) and the exponential shifts (that I assume would have been associated with them) in the graph that would indicate a sturdy argument for pro-manmade climate change. (although it does seem to be consistently rising which may be a bigger problem altogether). Just saying, shouldn't the trends be variably sharper and stabler across the board in specific areas? brain fart.

  • Let's see whose side I'm on that argument. Some people that don't have degree in science or even if they do it is not in the sphere of climate and weather on the Internet or approx. 97% of scientists in that climate studying department across the world? Yeah I believe there is a climate change and if you ignorant pricks don't so you don't have to feel obligated to change my or any of the scientists opinions. I wonder if you (not believing in climate change people) put your hand in an oven when it just started and you set a temperature of 60 degrees celcuis lets say, would you keep your hand there for much time.

  • Does this guy know that he's also contributing to Global Warming <3. He's actually really hot.

  • This video has more scientific misconceptions than Al Gore's movie…

  • Loads of graphs there, I wonder why they missed this one: https://faculty.ucr.edu/~legneref/bronze/jpg/climate.jpg

  • How can there be this many comments from people who are naive to the fact that the fossil fuel industry is the force behind the denial of human-caused global warming? Absolutely amazing..

  • Wow I’ve been pretty ignorant for about 4 years in this topic, believing about 50% of the misconceptions. I am ashamed.

  • Your strawman looks better than you.

  • Co2, emissions, deforestation, pollution all comes down to Human population. Lesser people means lesser demands.

  • GOOD JOB

  • Tell India and China to use less fossil fuel. Global Warming theory is racist!

  • You are taking science advice from a guy wearing SUN glasses indoors!

  • It is cute you get some info and suddenly think you know it all

  • has plant lift significantly improved growing?

  • We only have data of the past 50 years at best! We are Drawing a conclusion from a very limited data and constantly extrapolating it ! Yes the world is getting warmer recently (from 1990-2006 DU archive published in 2008 ) but the data is insufficient to say that Climate is changing! Its a fact that Global warming is increasing recently but we no nothing about the past 20 centuries maybe its fluctuating , maybe it keep on rising ..No one knows!

  • How about the elephant in the room AIR CONDITIONING. use over my lifetime has gone up probably 100 times. And why dont the liberals talk about this. it would disrupt facebooks business model. Plus Why arent the democrats talking about us all putting plants in our houses to combat co2. It is because the government is more worried about getting revenue than actually fixing the problem. making people buy new cars creates tax revenue. making people buy solar panels creates tax revenue. Changing stuff creates tax revenue. Stopping using air conditioning stops tax revenue because people want to work in offices. WTF. The dems are a bunch of liars trying to get your vote to do nothing about the problem but raise your taxes. DONT YOU SEE IT..

  • Earth's climate fluctuates. Don't get lied to by saying life will end because of temperatures, and God promised not to flood the earth again, so just move if it rises! The carbon is relatively low compared to passed ages, so don't worry about a thing! Don't let the left use these fear tactics!!!

  • So nice how critical search words lead up this video. Big AGW brother really wants you to believe their bs, hallelujah 😂

  • I'm just curious where you get these numbers. How could you possibly know the amount of CO2 released by volcanoes in the past decade. You have no idea. Nobody else does either. Somebody gave you some numbers and you're rolling with it. You also failed to mention how the CO2 levels have been really high and really low in the past. Wouldn't that suggest that these phenomenon are natural. The planets going to do what it's going to do. We're just along for the ride. By all means reduce your carbon footprint, but don't have the audacity to think that mankind has any control over nature. The planet could fart tomorrow and we're all gone.

  • Hold up just go back to point 11 in regards to the cycles.

    I didn't follow your logic as to how modern temperatures Cannot be explained by them seeing as Vikings used to farm in Greenland about 400 years ago.

  • Climate change? Please explain the past civilizations that are gone. It's due to earth moving and changing. Maybe buddhism will help you with this. Let me guess, the magnetic poles are moving because of humans? Please stop.

  • wow, still telling the same lies for the last 5 yrs, at least.
    sea ice graph starts at 1979, the coldest yr since.
    if you look at the big picture, pre 1979 sea ice was much lower in the 1930's, expanded till about 1979 & has declined slightly since
    ABSOLUTE PROPAGANDA BS
    go out and buy some integrity as its clear you have none

  • I love the fact that you cite the source feels good

  • Instead of talking to yourself to "prove" your position why don't you film an interview with someone like Dr. Juditch Curry or another climate scientists who question the current paradigm on anthropogenic climate change!?

  • Can’t believe i’m watching a guy argue with himself.

  • You have to take into account how tainted everything has become by politics. I certainly believe humans play a role in climate change, but when colleges are known to have very leftist bias, while the vast majority of the media is left, and they are constantly finding any and every reason lie and dump on conservatives at every chance they get, how do you expect people to react? I'm not saying denying climate change is justified, but can you blame them for people skeptical given the vast amount of bias that exists in mainstream media and the intense hatred most of these companies any organizations have against conservatives? It's weird polarized things have gotten in recent years. People keep saying is because Republicans are so stubborn, which has historically been true, but the Democrats are no better, in that sense.

    Just a sad side effect of social media and the tribalism it promotes. You catch a lot more flies with a drop of honey than a gallon of gall.

  • Blah, Blah, Blah…

  • Actually, increased solar activity should be associated with lowering of global temperatures, not the other way around. this is because the solar wind given off by the sun is a catalyst for cloud formation. Clouds increase Earth's albedo and thermal radiance (since water vapor condensing to liquid droplets in the atmosphere gives off heat which is radiated away into space). This means that the decrease in solar activity leads to less cloud formation and more heat absorption.

  • how do you know we will get more intense storms or more droughts or floods? how can you make that prediction, the earth has been warmer than we are on trend to make it before.

  • You just pick whatever date range fits your narrative for these graphs…gotta love it.

  • Somehow ended up here after watching a bunch of videos clearly explain the data and exposing the fake science. And you, my friend, just told 13 lies.

  • It is natural causes – not human activities mostly. The Co2-gas that is supposed to be bad for the climate is a natural "gas" that exists with or without people activities. It is a gas that is A MUST for alll life to exist in this world – it is the gas of life. The atmosphere has very little of this gas in the atmosphere – less than 1 percent of the total "gas". And the atmosphere has had different levels of co2 during different times. Historicly we have had great up and downs in the climate temperature. And the serious scientists know this – it is just the politicians and journalists that change the facts and give wrong information to the people. Many scientist might also live on feeding this lie to the people – because if they do – they get more funds and money for research. It can not possibly make a great difference with a gas that is so tiny in the atmosphere.

  • No offense but most of the Americans I have met are not that smart

  • Why do people have the auts

  • Amaizing!!!!!

  • Y’all don’t believe ur old friend who lied to u , but u keep trusting the lieng media and scientists who say man can be woman and global warming and wmds! 👍 🤣🤣😂🤣😂

  • Damn. Too think that the 7.7k dislikes are all right-sided wannabe politicians who can't/wont deal with their mistakes in the past and instead giving us (the younger generation) the load to deal with their problems. I commend Greta Turnberg for her courage in her voyage to end climate change. Im sick of people such as Trump throwing away climate change reports in such an arrogant way that he makes it seem like the reports werent made by top scientists. The fact that he has the audacity to throw it away and think that he knows better that licensed scientists makes me sick to my stomach.

  • No mention of carbon sequestration. Hmm…

  • Please make an update video because there has been a lot more research that has been released recently on this topic and changes the debate behind climate change. It kind of debunks global warming but not all the way so still room to talk.

  • This does not justify the Green New Deal.

  • Shhh. Don't tell anyone but if the globe warms it will save the rain forests. Which in turn will curb global warming. See that balanced out also. The earth has a way of doing that.

  • A BlueCross BlueShield study found, "Diagnoses of major depression have risen dramatically by 33 percent" between 2016and 2019. They contribute to "the trump effect". 
    Life expectancy decreased between 2014 and 2017 — falling from 78.9 to 78.6, according CDC figures. Last year, the CDC director called the decline in life expectancy a "wakeup call that we are losing too many Americans, too early and too often, to conditions of president trumps policy's on climate change. These are preventable.

  • Tis is stupid

  • "We didnt listen." -Randy Marsh

  • Maybe you aren't the right person for talking about this theme. So I would not say that I know it better but to avoid do the wrong thing, it would be better to not do it. So I do not salute you!

  • The irony is that BOTH alter egos are YouTube and both are giving out faulty info. This just goes to show that someone may be extremely intelligent in a narrow field of studies (e.g. physics) and quite misinformed and perhaps downright stupid in other areas (e.g. climate change – global warming).

  • Looking on 2019 and I'm like okay. #FridaysForFurture

  • I really enjoyed how he doesn't at all address that plant life is optimal with around 1000 (typically in the 800-1200 range) ppm co2, so effectively plants are starved the way things are now. Or just jumps at the 400 number of co2 levels when it varies from 250-400 depending on where you live. Or that plant life thrives because it breathes in co2 and exhales oxygen. Or that sea levels have been rising for 10,000 years now. Or how some of the warmest days are in direct correlation with sun spots.

    It's a complicated issue and it seems you don't have the first clue on much of anything. Good luck i guess.

  • No sane person denies climate change. But some insane people use it to justify all out socialism.

  • 2014 no
    2015 mmmmm. Next year
    2016 no
    2017 just a bit longer
    2018 wait
    2019 k now
    2020 well wait again
    2021 more waiting
    2022 AGAIN!!

  • Catastrophe? That is the actual point of contention. It would probably help your credibility if you cited the potential benefits of climate change. But, admittedly, adapting to change would probably cost a lot of money. And the Alarmist's solutions don't hold water; you can't destroy the world economy. And you have to argue for nuclear power, regenerative agriculture, reforestation, and there will certainly be new means to reduce carbon or increase sequestration of it. But the Leftists argue for silly, feel-good technologies like wind and solar; those are non-starters for serious people.

  • Veritasium gets OWNED by wait… is that Veritasium?

  • Our earth was formed billions of years ago, hit by many asteroids, lost half of its mass for the moon, was hostile due to volcanoes and yet we think a little climate change is going to kill us? Please

  • The global net carbon was not at balance it was declining gradually before humans entered the picture

  • I usually like your videos, but you lost me at just 37 seconds in! 'Ocean acidification'?!?! The oceans are NOT acidifying. They are becoming a tiny (and I mean tiny) bit less alkaline. That is NOT the same thing as acidifying. And yes, this is my field of expertise. Acidification is an emotive term purposefully used to make it sound like the oceans are turning to acid. They are not, and they won't. Anyone who uses the term cannot be taken seriously. We should be having a rational debate about what, if anything, is going on, not using terms meant to alarm when they those terms are just plain incorrect.

  • Great. Now, get this video translated into Chinese, Hindi/Urdu and other Indian languages, and the major African languages. Without their participation in whatever efforts are made, we'd just be pissing into a hurricane.

  • It’s cold outside. Whole video destroyed

  • Its chinas fault

  • But is 41 degree celcius normal in germany?

  • It takes a special type of fuckin moron to burn his toast, then blame the god damn bread.

  • I like the way how most of the things taught wouldn't have even been known to be called misconceptions

  • 😂😂😂 storms, hurricanes etc… DO NOT happen because of warm air. They happen because of COLD air rising. So by saying it’s global warming is FALSE.

  • Your GRAFS ARE IDIOTIC!!!

  • LIES!!!!!!

  • I see your point, Derik.

  • Id love to watch Tony Heller reduce this brainwashed twit to mush in 30 seconds……no 5 seconds

  • The term "climate change" is a terrible term because climate is dynamic. It ALWAYS changes no matter what is done. Humans do not have the capability to make it static.

  • "Before us the system was in balance." Rubbish. How much CO2 was in the atmosphere during the Jurassic for example?

  • Would say you're doing God's work but I'm atheist. So instead I'll just say gj.

  • Re: milankkovitch cycles – it has been shown that CO2 has a more determined effect on global temperatures than milankovitch cycles, as the earth only became susceptible to these cycles (and glacial / interglacial periods) when CO2 dropped below a certain level due to the formation of the himalayas…

  • So global warming flood are not as bad?!

  • Science lies when it states Water is composed of H2O – in reality water is an element! Air and water are the same element cycling between gas and liquid states.

  • Once warming has been trigfered the is no turning back cutting CO2 now will not revert the trend.

  • Good video, of course based on never refuted Physics of Radiative Transfer with AGW conceded by ExxonMobil's 1982 report affirmed soon after by Shell with their climate predictions accurate within tight error bars.

  • The question I have. The scientific establishment routinely manufactures crises. I've lived through a lot of these. Y2K, asteroid impacts, the hole in the ozone layer. I look back in history and see even more. All evidence points out that the scientific establishment suffers from the same bug as general humanity suffers in making absurd predictions about the end of the world and manufacturing evidence to support these predictions. What's different about global warming or climate change or whatever the current name is that means I should trust it? I get that the boy who cried wolf was eventually right. But what makes us so certain this fad is legitimate when all the others were not? How do we know this science is actually valid when the seemingly valid science of the past was revealed to be nonsense in retrospect?

  • An actual video concentrating on facts and reason rather than hysteria and misrepresenting the information to push an agenda. I salute you good sir.

  • We're coming out of the pleistocene ice age.

  • This global warming has come from cutting hardwood forests and replanting with pines or not replanting at all, been happening heavily for the last 100 years. Pine trees don't take in carbon dioxide and release oxygen like hardwood trees do.

  • What ever happened to planting trees?

  • How's about those clear cuts?

  • "Science" of climate change??

    Where's the model? Every actual scientific theory, has a model. Where is the model? Just to my right, I have a machine that is more powerful than a Cray super computer was back in 1995. I would like to be able to run a model on that, make predictions with it, and then test it.

  • Global warming is a fraud. These are the same scientists that can't get my weather 100% accurate or detect an earthquake more than 10 seconds in advance? Please read the book of Revelation. Global warming is not real.

  • I identify as a cooling earth…. so you can't question me . Don't even try it.

  • Not proven science. Man made Global warm is Theory …. like evolution and gender identity politics. They claim to be so scientific and totally ignore science…..

  • Dude ‘it’s not the sun’. Two minutes ‘it’s the sun cycles’.

  • Our solar system is less than 0.00919 megaparsecs from falling into a black hole and you are worried about global warming, freaking priorities man!

  • turtles!

  • Time for an update dude. This dated video is destroying your credibility. Here's a non-politicized version. https://www.youtube.com/watch?v=UFHX526NPbE&t=186s

  • Yeah, colder atmosphere is heating warmer Earth. Sure!

  • This is all well and good, but 'Climate Change' has become the darling of the Far Left and it comes w/ a nasty pkg deal.
    Oddly, the guy in the shades didn't broach that subject…
    We all need to live better and we need to grow MORE TREES.
    These CO2 issues are mitigated by TREES…(and us not being such fukwads)
