I wasn't worried about climate change. Now I am.

people simply aren't interested in giving up their fancy lifestyles, nor industries, governments, etc... honestly I think this is devil work, he has fooled us and the solution is start being humble and re-build the entire economy

I'm not wealthy you know, my carbon footprint is nothing compared to someone, who is considered a millionaire or even billionaire. As long as they doesn't adapt with their behavior, I don't give single mingle fuck. I'm not flying private jets and I dont drive supercars around the town, burning 3x as much tank as with my little car.

If the world is going to heat up or cool down,there is nothing we can do about it. The earth has its own agenda and we are not the cause

you are a scientist and you were not worried about climate change till just now??? Wow.

It's even worse than you think, because Sabine is assuming climate scientists know what the effects are going to be with each bit of temperature rise. They've been consistently underestimating the destructive effects. So not only will it be hotter faster than we've thought, but it will be more destructive than currently imagined.

Please keep us posted on what this number ends up being. Most of us wouldn’t have heard about it if not for this video and I doubt we’ll hear about the follow up publications.

People dislike these messages because MSM choose the worst most unlikely model. Al Gore started this, people remember and see he was lying so why would they now talk the truth? You did it yourself unfortunately. How many years have the Maldives been under water for example. One thing we can agree on Nuclear power.

I switched off when you said mid 19th century and then showed data from 1982 and 1979, late 20th century😢
On the other hand, what makes you think humans ought to be saved? Why worry for someone who did this to themselves?

This sounds like climate scientists trying to cover up for the fact that none of their scary models match observations by finding tenuous correlations with other phenomena. Fact is, the models shown no skill at predictions. Case closed.

Sabine here has very clearly fallen into that cliche of being a mind praised for her brilliance in a very specific field pf academics, and then drawn the conclusion that surely shed also be brilliant in any other field after considering its claims and research for an afternoon - only for her ideas to be woefully naive.

And i know i should be able to separate someone’s social and political views from their work (for instance if no one had ever read heiddger’s philosophy on account of his rabid nazism, 20th century philosophy would be immensely poorer for it) - but for some reason, i really struggle to do that with ms hossenfelder here. I guess it’s because i always tagged her as holding somewhat progressive values and leanings, but the more i hear from her, the more disappointed i am to hear how conservative and regressive her worldview seems to be. Ah well. Maybe i can learn how to extract just the physics from her videos, or idk, there are plenty of other physics channels of equal caliber who at least know the boundaries of their expertise and to not have the arrogance to pronounce of those subjects that lie outside it

It seems like those that care are the ones who can’t do anything about it.

Oh Dearie, the front-line scientists at major organizations like USGS and NOAA have been ordered to under-report data and only publish the most unrealistically conservative versions of their projections for like 30 years now (yes I know some of them). If you saw what their real projections looked like even 15 years ago, you would have been freaking out all along. Let's just say... "Say goodbye to Miami, Jakarta, Venice, and a bunch of others during your lifetime." And that's BEFORE the last 2 rounds of increased projections.

The climate/ecology folks literally had 3 levels of models they were using. The mindlessly hopeful one they were allowed to report to the media and UN etc, the conservative one they themselves hoped would happen "somehow", and then the realistic one that had tropical fire ants as far north as the Dakotas in the USA, with 5°+ celcius temperature rises, and over a meter of sea level rise by 2060... and that was BEFORE they found out how fast Greenland is really melting (because of massive cravassing) in the 20-teens, and before they realized just how much methane is really coming out of the arctic shorelines' permafrost, and before taking into account that polar sea ice shelf areas were actually being inflated because fresh water melt on the surface freezes easier.

At this point, the arctic shoreline/permafrost melt is starting to overtake even the CO2 issues, and methane is a mighty heater. Forget about cows. There are many thousands of kilometers of permafrost releasing tens of thousands of years of microbial-sourced methane in a hurry, as well as waking up those microbes to keep producing. It probably won't turn earth into a new Venus (for reasons), but it will solve that pesky problem of high-priced real-estate on up to 5-10 meters elevation in the next few decades.

The real effects of "climate change / global warming" have been masked or stunted up to this point by the ocean's gas-absorbption and thermal buffer effect, particulate issues, and lagging albedo changes in high altitudes. All of those factors are now nearing saturation, so you're going to start seeing the real deal in a couple years.

Nobody wants to hear this, they rather shoot the messenger.. we’re doomed.

Democratic party = in bed with big oil.
Republican party = in bed with big oil.
These are two identical things pretending to fight over climate change. The ways the democratic party has taught us to fight climate change won't work, they're meant to fail and divide us. At this point it is almost entirely pointless to fix climate change by talking about climate change, but instead to win we must unite against both parties.

Used to be global warming then climate change ! Ohh how about the ice age we were supposed to be in by now ! Uhhg !! What is happening right now is the solar system is goes through these cycles & we can’t do chit !! Yes , it is good to be nice to mother Earth 🌍 but we aren’t going to change something we can’t control ! Please stop being fooled bye these videos of hers !! Do the Research !!!

The species won't go extinct from the heat, but it could well die from political consequences. The wars could be quite bad -- nuclear. That won't bring extinction by itself either, but it too will have knock-on socio-political consequences, which could get worse.

Even moderate comments, which relate to other scientific literature are completly deleted here. Why that? Who is afraid of an open discussion?

climate change? my life is more climate than climate change now

One more thumbs down in case you thought you might have provided any reason to change my mind.

Please include links to the articles/papers you refer to, so that people can read your sources. Thanks in advance.

Do your research people !! They are lying to you. This lady just wants her grants !! They have been telling this fear story forever !! Never to come true ! It’s to control us . If you think this is real & what she is saying True , then you are a fool !!

Love your work. Never cease ❤

Once you said you advocated for "Carbon tax" on C²O emissions—you lost all credibility as a "scientist", to me.

Heat is not going to kill us,
Lack of potable water will leave us dead long before that.

Let’s just stop producing CO2 then. We don’t want to cause any problems in the world.

I still dont get how one model doing well in a 10 day forecast pushes your fear neurons so hard. To me that is not conclusive at all. you need to run all models and see how they do in someone of a longer time frame to start panic ing like this.

This is likely an example of p hacking. were a study fails to affirm what was intended, so the researchers go looking for something with a p value that will get published. As Sabine has pointed out in a video about the reproducability crisis, p hacking produces junk science that cannot be reproduced, but does get published. but it gets worse because these people went "ok our model doesn't predict the temperatures even as well as these other models that are way off; even with the manipulationof the temperatures upwards. But our model predicts the weather better than those models, none of which were designed to predict weather. Therefore our model is right about future temperatures. Just hit me in the head with a hammer.

"Let me take you down
'Cause I'm going to strawberry fields
Nothing is real
And nothing to get hung about
Strawberry fields forever..."

Carbon tax bad for average person. Costs cause them to use more fuel to go to work more often, commute to higher paying job or other business ventures to pay for the extra taxes. Cancels out good most likely.

If we are in danger of climatic shifts and sea level rises, not sure nuclear is smart since it requires constant power to keep from melting down - Fukashima situation for example, would not be optimal.

Thanks Sabine for another wonderful and relevant presentation and I would like to add there is a much better model of weather change and temperature increase related to the sun cycle.

As you will already now this cycle is every 11 and 22 years based on the periodic rotation of the sun's magnetic field towards the elliptic (the planets), each pole to pole being 11 years and the full north to north rotation being 22 years but there are harmonics related to these cycles that force related weather cycles of 44 and 88 years that are obvious and those up to 1408 years that are not. You can see the direct effect of the 11 and 22 cycles and if you are much older that of the 44 year cycle.

It became obvious by the recent wet weather and major flooding in Australia and other countries over the last 4-5 years that the degree of devastation wet/cold weather has been commonly referred to as bad as that back in late 70's when this flooding was extreme, some 44 years earlier. The worse part of this cycle, the dry part, will see major droughts with the current change over from the wet to the dry part of the sun cycle in the next year or two and will be as severe at that of the early 80's where thousands of farm animals died from lack of feed because there were no feed from crops or were shot and bulldozed into large graves.

I have been following the relationship between the sun cycles and weather now for some 50 years and for some countries like Australia as a large island mass, these cycles are more obvious. Having discussions with pro-carbon supporters who insist that the sun's irradiance has not changed over the last 75-100 years then the sun cannot be the cause of climate change and this is true. However it is not the sun's (ir)radiance that relates to climate weather on earth it is the magnetic field of the sun, in its pulses, solar flares, polar maxima and heaven forbid any mass corona ejection (I refer here to the Carrington Event back in 1859 where magnetic ejection powered telegraph lines and communications, electrocuting some operators and worked without the use of batteries.) If such an event happened today it would wipe out most of the satellite communications system and large part the unprotected technology systems around the world.

The current large cycle of 1408 years will peak in the mid 24th century and unlike the last 50 years, while we were not alive we can see similar sun related cycles at a low of wet period in the mid 17th century (generally referred to as the Maunder Minimum), a dry or high temperature periodic in the mid 10th century (relating to Viking navigation and exploration 'Greenland'), then cold/wet in the 2nd century, high/dry in the 5th century BCE and cold/wet in the 12th century BCE etc...all historical past periods.

At the end of the day the pattern changes are there, albeit minor in the overall scheme of weather changes for the earth as a result of the changing and rotating magnetic flux of the sun and nothing else, not carbon, not human (as the 10th was not industrial) and will not abate, no matter how much disastrous renewable change countries bring about in a panic to fix this issue. This long term, 1408 year sun cycle will continue doing what it does to provide variation and ecological change to the planet as it has done since at the least the great deluge of the 12th milliard BCE.

If we approach this change with a more pragmatic process of protection to the socioeconomic cycles, everyone and country, we would be far better off than the psychological stress and wasted taxes that is being caused by the panic of well intentioned science, political groups and individuals around the world. To use your words Sabine, I am not worried about the inevitability of climate change, I am worried about the disastrous political drivers, social events and the stress it is causing everyone especially children.

I wonder if anyone did what I did - checked the oxygen levels on Everest, over time. I thought that if we think of oxygen as a flood of gas, and it is diminishing and being replaced by other gases eg CO2, then we ought to be able to explain why Sherpas of the old days could climb without oxygen tanks and some still live, and get a measure of how fast we are losing our precious O2. No surprise, it’s diminishing. In other words, if you could walk around at 7,000 feet and feel fine before, say 20 years ago, you maybe won;t be able to now. And one day, as the usable level of oxygen becomes only available at a lower and lower altitude, people living in some higher areas, will have no energy to do,anything. They will be forced to migrate downward, literally being chased by a cloud of poison gas, in effect.

Personally, I worry about this rather than the surfeit of other gases. I think, this is the ‘sleeper’ problem that humanity is largely not aware of. Never mind executing some murderer over in Alabama by Nitrogen suffocation - we’ll all be getting a whiff of what that’s like in due course. Plant trees, it’s an easy solution. In the UK our govt ignores this…they say it wouldn’t make enough difference, so why bother?! I mean, FFS. I ain’t waiting on Brazil to take action. I have planted a handful of Birch trees and that’s all I can do, governments, get on with the big numbers please. Take care all.

You most disliked video are about Climate Change—because Climate Change is a hoax.

"Climate Change" scientists are to "science", as psychologists are to the medical field.

getting old has 2 compensations, better than dead, and who cares if the young ones die of heat stroke..
back in the 1960's, i started telling people that we should get democracy, because politician-rule didn't work.
for many reasons, because they were crooked war-mongers seemed pressing then.
but it turned out that their utter inability to look past the next election is going to kill us all.
well. you all, i'll die smiling, of old age, and whispering, 'i told you so, but would you listen.'

dr h has finally seen the light, and is well-placed to inform many. but i'm afraid she's seen the light too late. it's now quite possible that 5% warming, or worse, is baked-in, neither physics nor politics can turn the ship of state.

Last year, Rio de Janeiro (Brazil) experienced a week of summer heatwave with thermal sensations that eventually peeked 58 °C or 136 F. That’s just horrible, life and economy threatening, an expensive burden for us to deal with, and it’s happening also in many other places that are even poorer and prone to social unrest in this world. “We’re doomed”, C-3PO would add.

f the climate scam !!!

Al gores movie “inconvenient truth” is the worst thing to ever happen to climate change. He had good intentions but being a career politician he inadvertently drew a line in the sand with the release of that movie. When trump was president Biden said he wouldn’t take the covid vaccine, then biden became president and then wow all at the sudden the vaccine was the best thing to happen since sliced bread. The point is, quite listening to politicians and do your own research.

How much did they pay you?

No, Sabine, we don't have a means of controlling the global climate. What we do have is a means of bankrupting the world trying to achieve what is beyond our capability, especially when the proposed solutions only restrict the wealthy nations, rather than the actual contributors of CO2. Your warnings are alarmism and misdirection, not because climate change isn't real, but because the non-climate world doesn't work the way you seem to think it works.

Few people, if any, have died due to a natural famine in a century. Similar to your presentation of climate change, the presentation of modern famines covers up the very human, short-term stupidity that causes them. Wars are a large cause; so are bungled government policies, even in peacetime. Climate change isn't going to cause mass deaths due to famines; human actions and reactions to a variety of issues will.

Likewise, people are not immigrating because their nations are going under water or experiencing bad effects of climate change. They are immigrating because they can (or think they can) get a lot of money out of wealthier nations, or because some Marxist or Islamic (or both) dictator or militant group has decided to exterminate them. Virtually all violent conflicts in the world for the last fifty years are due to Marxist/Islamic militants killing anybody who crosses them; climate change hasn't.

The real world has a lot of issues right now that people are killing each other over, so don't pretend that these will start because climate warms five degrees. These are the products of human nature; it's just coincidence that climate has changed while they are taking place.

My parents told me it used to snow so much in Chicago that you could sled off of the drifts against houses. During my childhood into adulthood the snow doesn't stick for more than a couple of weeks, which isn't nearly long enough for it to build up like that. I took a walk with someone just last weekend who'd lived in this particular part of Wisconsin for over six decades and he never the particular ponds we passed by thaw like they have this winter. They used to stay frozen the whole winter.

What sucks is that we see blatantly what's going on, so many people see it with their own eyes, but the ONE time it's cold Fox News can say "well it was cold today so where's climate change?" They say it indirectly (they had a headline where they pointed out climate plans while it's also apparently cold outside) but it really brainwashes people. How can people not remember last summer that broke records? But it's cold TODAY so obviously nothing is happening. Ugh.

And another annoying thing is that so many Americans claim to be Christian but will do absolutely nothing to change the way they live so that resources can be distributed fairly. You don't even have to believe in climate change to do that and it would still make a positive difference for the environment to try to waste less.

The numbers are wrong and alarmist climate change is not real science, that's why people thumbs down.

You are a very clever person. Please keep doing this !! Mark, New Zealand.

Tired of it cus me and my country aint the f problem

Good to know our biggest problem is with Hot Models 😏

I love you ❤

You thought you were going to escape, didn't you, Sabine? You thought this collapse would only happen decades, maybe centuries after your death, didn't you? You won't escape.

i´m not worried

Climate is a period lasting 30 years, so wait that time, instead contradictory are predicted based on a year or so. That is absurd.

Oh no! Panic! Panic! We're all going to die.

Damn it's almost like the sun is going into a cycle that's affecting our climate, wow. Maybe we should listen more to WEF, it might save the Sun
