Of course.
It was predicted in 1896 by Nobel winner Svante Arrhenius.
This simple article by NASA introduces Arrhenius as the first one to predict global warming:

Svante Arrhenius (1859-1927)
by Steve Graham • January 18, 2000
A hundred years ago, Swedish scientist Svante Arrhenius asked the important question “Is the mean temperature of the ground in any way influenced by the presence of the heat-absorbing gases in the atmosphere?” He went on to become the first person to investigate the effect that doubling atmospheric carbon dioxide would have on global climate. The question was debated throughout the early part of the 20th century and is still a main concern of Earth scientists today.
=======
So why did Svante Arrhenius predicted it in 1896
Because it is basic physics.
Any competent student of physics who had reached the point of understanding basic kinetic theory of gases and statistical mechanics (so, basically, a second-semester freshman), should think "Duh."
This is why in a nutshell...
1. In physics, molecules consist of atoms with electrical bonds between the atoms that keep these atoms together.
2. If a molecule has only 2 atoms, then there is only one bond between those two atoms.
3. However, if a molecule has more than 2 atoms, then there are at least 2 bonds.
4. Now, this is the first thing that is important: These bonds are like rubber bands and can store energy.
5. So, the larger a molecule is, then the more bonds it will have and the more energy it can store.
6, Stored energy can be released and that causes motion. For instance, think of a slingshot. When you pull back on the rubber band in the slingshot you are putting energy into that rubber band which stores it. When you let go, the pebble in the middle is suddenly flung at high speed because the rubberband stored released its energy transferring it to the pebble. The pebble now is moving and we say it has kinetic energy (the energy of motion).
7. So, think of all these molecules with extra bonds as having all this extra energy that can cause other molecules to move faster when they collide.
8. So, as these molecules are bouncing around, they are exchanging energy with each other, but because the larger molecules can store more energy, they can release more energy so, when they bounce into smaller molecules, those smaller molecules are more likely to move faster.
9. Now, the average speed of molecules in a gas is related to the average kinetic energy of the molecules. In fact, if you double the average speed, then the average kinetic energy will go up by 4 (=2^2).
10. Now, this is the second important thing: Temperature is directly related to the average kinetic energy of the gas. So, if you can double the average kinetic energy of the gas, then the temperature doubles as well.
11. So, when you put all this together, it says that if you increase the number of larger molecules in the gas, then you will increase the temperature.
12. Remember that the molecular bonds have to store energy. Well, the sun is the major source of energy, so all these extra larger molecules in the air are just absorbing more solar energy and by colliding with other molecules ultimately raises the average kinetic energy of the air and thus its temperature.
That's global warming in a nutshell which can be summarized like this:
1. More large molecules in the air causes more solar energy to be stored in the air which
2. Is passed to all the other molecules in the air due to collisions so
3. The average kinetic energy of the molecules in the air increases and
4. Because temperature is really the same as average kinetic energy, the temperature increases.
Just to finish up... Most of the air is made up of:
1. 2-atom nitrogen, N2 (about 78%)
2. 2-atom oxygen, O2 (about 21%)
3. 1-atom argon, Ar (< 1%)
But the rest of the air is made up of larger molecules - molecules with 3 or more atoms. For instance, carbon dioxide, CO2. Water (H2O) too. And many other molecules too. But notice that these are larger molecules so they can store more energy compared to the N2, O2, and Ar. These larger molecules are called greenhouse gases because of their ability to absorb and store more energy and thus raise temperature like a greenhouse.
The problem with global warming is that, since humans started burning coal and the Industrial Revolution began over 200 years ago, we have been dumping a lot of CO2 into the air during all that time, so, as a result, the temperature has gradually been going up in response to the extra CO2. This is what Svante Arrhenius was worried about because he realized that all that burning coal was dumping CO2 into the air and that CO2 would store more energy. That's why he asked the question describe in the NASA article: “Is the mean temperature of the ground in any way influenced by the presence of the heat-absorbing gases in the atmosphere?”
Global warming is very real.
I'm not sure how else to put this, but this same ___basic___ physics and chemistry explains why Venus and Mars have the atmospheres that they do - and it explains what is happening now. It's not good. Don't invest in beachfront real estate.

Yes, of course. The scientific evidence is overwhelming.

I believe that our climate changes over time. It has done that for as far back as we can determine.
The question that separates people or triggers them is: is current climate change caused by the activities of our species and would it revert to a pre-existing state if we eliminate our activities?
For me, the answer to the second question is unknown.No. However, certain concerns that are brought up by the "belief" do warrant investigation. Global warming was debunked back in the mid 90's (I know because I was a little kid at the time and still remember the broadcast...) There is also the fact that all of human civilization only contributes 1%, 2% if you want to push it, of the total carbon on the planet, the other 99% is produced by the planet itself, which has been known and proven for decades. Also, we are carbon based lifeforms, meaning that we actually need the carbon to survive. Plants absorb the carbon in the air and then separate the carbon from the oxygen and other elements spew out breathable air for us. Plants actually grow faster and bigger with more carbon, not less. We humans have next to no effect on the weather, which has been proven to be driven mainly by the Sun. Without it, we grow cold and die, but there would be very infrequent, mild weather patterns still due to other factors. There is no such thing as a "weather scientist", there are however meteorologists and climatologist, and most of them disagree with climate change. That is what climate does, it changes, which is due to many, many factors other than us. The continents drift, volcanoes erupt, meteors impact the Earth, etc., all of which change the geology of the Earth which in turn changes the air currents and temperatures of the surrounding areas which changes the weather. The seasons change due to the tilt of the Earth and its position relative to the Sun. In mid January, the Earth is closest to the Sun, but the Northern Hemisphere is tilted away from the Sun, so it's the same amount of light, but covering a much larger/spread out area, thus Winter occurs in the Northern Hemisphere while Summer occurs in the Southern Hemisphere. Take a meteorology or an astronomy, not astrology, course and learn it for yourselves. Before anyone argues with me, if you can call it that, please note that I'm an mechanical engineer, meaning that I not only deal in hard science, but the practical application of it to solve problems in the real, not political, world. I just specialize in mechanics, but my skills can be applied to a multitude of fields. Climate change came about as a talking point to gain funding for companies and research from governments, as in political nut jobs with absolutely no experience in science. Take away their power to fund or defund scientific research, and you'll see that research return to hard science and take leaps and bounds. Also, scientific "consensus" once said that the world was flat, food for thought...
Of course I believe in climate change but I believe the scientific research being told is bull shit! The world has literally shifted we didn’t have seven continents millions of years ago. The whole earth has made massive shifts through it’s life without human life. Humans habitat changes act science research can not and will not change that it’s a FACT. Global temperatures climate around the world has also changed around the planet before we even had humans thats also a FACT. The ability to give 💯% accuracies to even weather isn’t even possible. They have give a pretty good idea by satellite 🛰 and get it pretty good most the time but that’s not accurate 💯 is accurate. They can maybe go out a few week but as the get farther away there isn’t any want they can tell. So for a idiot to buy the shit they sell I laugh saying in 11 years the earth is destroys who said that a stupid drunk bitch congress women bartender. It’s political that was it is feed the fear of the scared and weak minded scared the already fragile people who suffer mental health issues. My advantage I don’t have mental heath issues I’m not scared I go by fact. I don’t care what is political it’s how it effects and not taking bullshit. Anyways I really went off on yeah 😜
This is a silly question along with "do you believe 1+1=2?" and "Do you believe circles are round?"
A more pertinent question is "what do you believe the cause to be and how fast is it going to get bad?"
The climate has fluctuated tens of thousands of times in the last couple of billion years. It has been both five degrees hotter and five degrees colder that many times. I live in Florida 50 feet above sea level and I have fossil seashells all over my back yard which my geologist friend informs me is proof that the sea levels used to be more than 50 feet higher than they currently are. The question isn't "is there climate change?" The question is "what is causing it?" and that is a combination of things. The sea level today is a couple of inches higher than it was 40 years ago but 40 years ago it was lower than it was 300 years ago. It is constantly changing.Well pretty much the entire globe apart from the USA believes it.
The USA have made it a political point scoring thing.
remove the politics and look at the science.
even worse is looking at not just global warming but the impact of man on animals, insects such as bees, fish, reefs.
people can believe what they want however if pretty much the rest of the world recognises the problem, quite possibly there is a large problem,
the huge issue is going to be when oil use drops snd electric increases, countries that a high oil producers are going to see their economies shrink, slammed or collapse entirely.
so even of a person does not believe in global warming and the scientist around the world, well if you live in an oil producing country you are potentially shaggedYes, the climate has been changing for thousands of years between hotter and colder. To the extent that man has an effect on it has yet to really be determined. I’m not against the possibility that perhaps we may, but I have yet to see the blatant evidence. I’ve been warned that “we only have 10 years to enact major changes or it’s over!” Now since the 1980s and we are still about the same temp. And the Lefts hypocrisy is on full display as they do not address the real polluters- China and India. They are are only concerned with western countries for some reason.
Has there ever been a point in time when the climate was not changing?
Entire nations were supposed to be completely submerged 20 years ago if we didn't take immediate, drastic action according to the UN in 1989. No drastic action was taken, in fact barely even minimal action was taken and no nation is under water or for that matter even close. If the Earth was only years away from being uninhabitable due to the climate it would be easy to tell that just by stepping outside.
Global cooling I mean global warming I mean climate change is just another boogeyman the ruling class uses to keep the masses afraid. Once they can't squeeze anything more out of COVID they will be back to climate alarmism. Luckily the masses don't seem all that interested in making any real changes in the name of climate alarmism so unlike COVID, they don't seem to be afraid of it, even if they're dumb enough to believe it.
Propaganda works, but only to an extent.I understand, that science is not a belief system or an idology. It is a method to carefully and objectively use evidence to find answers. If that method is followed and replicated and consistently returns the same answers...
It doesn't require my "belief" it just is..
Anthropomorphic global warming doesn't need my belief. It's happening whether I believe it or not.Yes. In my lifetime I have witnessed a significant change in climate where I live, and it's quantifiable. The growing season is longer and crops that could never be grown here before are now regularly cultivated. It boggles my mind that (a large number of) the farmers who grow those crops still deny climate change, even as they've adjusted what they grow due to climate change.
climate change fear is a scam to put 4 trillion dollars in a bucket so the democrates can steal from it... there's always been fear of climate change from 24 years after jesus to 1976 check it out they had a real scare back then until now... changes in the weather and extreme weather has always happend... so do research... oh i forget the neatherdals destroy history.
It’s a real thing yes, The way we should fight it is adaptions like moving building sea walls using nuclear energy and nature gas. Instead of something like a carbon tax, if you think China and India are going to sigh onto that I’m sorry you are very mistaken.
carbon emissions are good for developing worlds. Most places in Africa will need to continue using fossil fuels for another 100 years
by the way I heard a stupid argument being taught on Nickelodeon suggesting that mining is environmental racism. Expect you need to mine in order to get the Materials in order to build solar and wind power. So if mining is racist all ways humans can get energy is racist don’t fall for that trapif you think "Forrest Management" in sweeping the forest so fires dont happen, and the glaciers melting just like that, in addition to smog and storms like Hurricane Sandy aren't due to "Climate Change" and no snow... where snow is suppose to happen (like in TEXAS) ...
All of the predictions that these "scientists made in 1990, 2000, 2010 have not come to pass. However this has gone on so long people don't remember when we keep saying the effect is 10 years out. Many people will no longer be alive or were too young to remember todays prediction when we create tomorrows "final warning"
the climate is constantly changing, mostly due to the sun. burning gas or coal has nothing to do with it.
I wish greenies would get us all aligned around cleaning the trash out of the ocean. That actually makes sense and people of all beliefs could get together around that.I do. The abnormal weather and the natural disasters that we see happening every year are the proof that climate change is real and needs to be stopped. We are destroying our planet and leaving a burden to future generations. Unfortunately since there is a lot of money involved in these changes that need to be done and most people are not willing to have a different lifestyle to save Earth this issue will never be solved.
More than half of our icebergs have disappeared are ozone there is going and all our government officials and all other country officials thinks that is just a big game that all this stuff happens for other reasons so I said why don't we stop everything that we're doing to make these things happen and let's just see if you need proof you need to stop all the bullshit in order to get the proof
Climate change aka human induced warming of the planet? Yes humanity is a factor are we to take all the blame no, but we definitely tipped the planet over the edge. We are effectively as we speak are forcing the earth to undo what an estimated 550 MILLION Years of evolution by killing off the Biology on the planet.
Chances are humanity isn't going to do anything to help the planet till either cities collapse or half the current continents are under water.climate change is normal it's been happening since the beginning of time. we've had ice ages and hot climates for millions of years.
when we find worlds like our we'll see it's totally normal. hell astronomers found lake beds on mars and saturn's moons.Climate change is a NATURALLY occurring thing. As of right now we are 11 to 14 thousand years overdue for an ice age, it’s coming, you can tell because the planet has to go into greenhouse mode before the Gulf Stream and jet stream reverse bringing the ice age. It’s been going like that in cycles for millions upon millions of years and will continue to do so. man made? Not at all, yes humans contribute, our oceans are trash heaps and need to be cleaned. no, if humans were responsible we would have destroyed the planet between 1944 and now with all the nukes we’ve popped off. Gaia can take care of herself and when she’s had enough she will cause humans to go extinct.
If you look back in time there are events that take place in cycles. The earth rotates on a 24 hour cycle, it rotates the sun on a 365 day cycle, and if you get closer to home there are weather cycles too. Back in 2016 we had a flood in the south and they called it a 1 in 200 years event. It has happened before for them to use the 200 year reference. Cycles and patterns happen naturally in nature. Is global warming one of them? maybe depending on who you ask. A Politian may say it is real but a person who really studies weather patterns might say not it isn't real.
However what they are not saying is that all of the concrete and roadways help to warm the atmosphere too. The more we expand the more we create hot spots. That is why it is warmer in the city then it is outside of the city a few miles.Climate change is inevitable. However, I think what you're asking is due I believe in human induced climate change? And my answer is yes. The research has been done and the results are in. Humans are contributing to the polluting and warming of the planet.
