Thankyou Lawrence, I will admit I have had my fears and skepticisms of climate change. However, I would certainly be willing to change my mind if incontrovertible evidence was shown to me. One of my biggest skepticisms is that in the media we are constantly bombarded with lectures from celebrities, politicians, and uneducated school children with no life experience, but where is the scientist? they don't seem to have a voice on this issue in mainstream media? You are actually the first scientist I have heard from What is the title of your new book?

The Physics of Climate Change

[@alimoda]

It is very disturbing to see Lawrence has less than 9k subscribers. Tells alot about this society...

[@Climate_Nexus]

It's important to understand that Lawrence Krauss speaks for the scientific consensus on climate change, which is backed by the work of thousands of scientists who rigorously peer-review each other's research. This consensus shows that human activities, especially the emission of greenhouse gases, are significantly altering our climate. When a scientist like Dr. William Happer disagrees with this consensus, it's crucial to recognize that he is an outlier. Relying on a single opinion instead of the broad consensus should be a red flag. In our current age of misinformation, some people fall into "exceditism." This involves cherry-picking a single authority who supports their biases, ignoring the broader scientific evidence, and often becoming aggressive when challenged. Genuine scientific understanding comes from considering the consensus, not the isolated views of a few individuals. When scientists are interviewed, especially on TV, and they speak in terms of "I know," this should trigger alarm bells. It often indicates a confirmation bias and a departure from representing the scientific consensus. Scientists should use "we know" or "we do not know" to reflect collective understanding. Be wary of those who speak in personal terms rather than on behalf of the scientific community. For these reasons, Lawrence Krauss has no valid reason to debate William Happer. Happer does not represent the scientific consensus, and his arguments have not undergone peer review or been validated by the broader scientific community. Debating him would give undue credibility to views that do not reflect the consensus, which is why such a debate would be pointless.

Prof. Krauss, you are a gift to the humanity. Wonderful explanation! I am reading one of your books "A Universe From Nothing". Loving every bit of it!

[@woody7652]

The pollution of the air and oceans, overfishing, tree deforestation, the killing of species, and more we're doing to our ecosystem, it makes me wonder if it's not too late. Great to see you back, and would love to see more on climate change here, and The Origins Podcast . Thanks, Lawrence!

Looking forward to the book! It'll be irritating to read because it will take us readers on a journey on a realisation that the life we life is one we don't really want to give up. We all love driving our cars. I love A/C. Life is so convenient with petrol and electricity. Thank you for all your previous books - I really loved the Oxygen life cycle book

Hi, Lawrence Sir, Please suggest to me how to utilize my mind & heart correctly so that I can do productive things/actions. The current reality is unreleased emotions, past hurts internalized & that replaying in my mind.

[@theo.r.bitter]

Hm, I'm not sure I'm on board with the this-sheet-of-paper-is-so-thin-but-so-powerful analogy. Yes, it's thin, but it's also how much more dense than air? I mean, I can walk through air and leave the air intact, yet I can't do that with paper, no matter if it's thin or even thinner. I guess I'm not understanding the argument.

How many atoms of a poison would it take to kill someone as compared to the total number of atoms in the human body? Might be a good way to point out that something that is a small proportion of a system can have a big impact.

Hello Lawrence . Please make more 5 minute videos , I am watching all your videos here. And if possible get your book transalation in other languages for more audience reach.

Excellent as usual; another great recipe for success. But, how long will it take to convince those who need convincing? Time is of the essence and though time is a great master... he always kills his students.

[@mrtyddet9726]

Very interesting video, I loved looking at the problem from this perspective and how such a small percentage of a gas can have such a big impact on life. Also, do you have any tips for how a high school student can get better at math/physics?

[@lkrauss1]

thanks.. just keep working at it.. it takes effort

[@luperamos7307]

So are we naturally in a cycle in which the Earth is heating up anyway? Or would Earth currently be in a natural cooling cycle? I am seriously confused about this because I have been hearing both claims.

[@richardedward123]

I hope I read the book, too! Looking forward to it.

[@yodafluffy5035]

Hi Lawrence Krause, can you explain if relativistic mass is real or not? Because in my school some teacher say yes, some say no...

[@doctorspockARTS]

I seek a human with a mind of your caliber to answer a question I have. If gravity equals acceleration and space is accelerating does that mean empty space can produce gravity with no mass involved?

[@kamalkatial1530]

What about the impact of the sun with things like, solar cycles, a solar flare is that not likely to contribute to climate change?

[@TheOriginsPodcast]

not individually and not on the timescales we are talking about.

Must have missed something.What is name of your book so I can order it.Will be sitting in local park all week explaining why we should not be allowing more coal mining in Australia for the Australian Greens Party as we have an election coming up and they seem the only group to really care about climate change in this country.As always thank you.Good luck with your upcoming election.

[@lkrauss1]

The Physics of Climate Change.. it is coming out in Jan.. so it may be too late for this election, but not the next!

[@lahshad]

The temperature of radiation coming from the sun will be high, hence high frequency less wavelength. But when these radiations reach earth and try to escape, it's temperature is less and wavelength is high, so it gets trapped inside. This effect can be seen when you are inside a car with widows closed.

[@skepticsapiens4149]

Is this book also in Amazon?

[@lkrauss1]

yes

[@ken0272]

Not sure I'm understanding with that explanation? (at lest the higher elevation radiation-equivalency point) Perhaps at the highest elevations there are no convection effects, moisture content is very low, atmospheric density is uniform.. atmospheric gas composition is uniform...if so then I get the argument. However, from fluid mechanics we know that no flowing fluid is uniform, except it's uniformly non-uniform..(my lingo...not very scientific) I always thought it (Global warming) was just that some gasses are better at absorbing infa-red radiation, on that point I am concerned about the permafrost in Canada's/Russia's North and Methane releases...perhaps there is a subject for Lawrence to help us with...

[@lkrauss1]

at the edge of the atmosphere the density is very low and uniform and almost moisture free.. the IR absorptions from CO2 (and H2O) govern the surface from which the earth radiates into space.. more detail in the book.

Hey, he uploaded again

[@fractalnomics]

Notwithstanding CO2 does not factor in meteorology or has any utility for what it is claimed to do anywhere else in reality, I have deduced there has been a systematic error in measuring the IR atmosphere that has played itself out over the last 161 years. We have relied on 19th-century thermoelectric detectors, what is termed IR spectroscopy due to its role in radiation history, and have not yet included the results from the modern laser-based IR spectrometer - claimed to be IR's complement, I say substitute - the Raman Spectrometer. Raman exploits the Raman effect to measure the quantum predicted spectra 'IR' cannot measure, ie the non-GHGs N2 and O2. It also measures their temperatures and is used with Raman LIDAR to model the atmosphere and can measure the Keeling curve. Read my work below, I am currently writing up an experiment proposal and aim to publish. PS none of the mainstream sceptics (AKA deniers) including Trumps advisor Happer like my findings. 'Quantum Mechanics and Raman Spectroscopy Refute Greenhouse Theory' vixra.org/abs/1811.0498 and while you are at it read 'The Greenhouse Gases and Infrared Radiation Misconceived by Thermoelectric Transducers' vixra.org/abs/1811.0499 and I also wrote this article: principia-scientific.org/settling-the-climate-woo-with-quantum-based-raman-spectroscopy/

It’s really disappointing that so many people are ignorant or aren’t aware of how much a problem man-made climate change really is. And with people like trump leading one of the worlds largest influencing countries, I don’t think it will get much better. We need more politicians who understand the severity of this situation and who follow the science.

You cannot do physics with hands... what you are explaining is totally unreal. The Romans had combustion engine cars that emitted CO2, which is why it was very hot in the year 0. The city of Pisa was underwater because the glaciers had melted. However, when the Roman Empire fell in 476, they stopped using combustion engine cars and the climate cooled down.

[@MrBendybruce]

What makes me truly sad is someone like Trump can send a meaningless message about Climate Change being a Hoax to countless millions of people across the globe, while a qualified science educator can speak with rationality and eloquence on the subject yet comparatively speaking be virtually ignored. Something is deeply deeply broken with our construction of reality.

[@VetruvianFebio]

Of course, we must blame Trump, as if USA matters... Nobody denies climate change, the last glacial age ended only 12K years ago. Even if you accept that global warming is human-made, most of the political debate is a mess of contradictions, it's all fight for shifting power. Science is completely compromised by the left, like many other fields, and it can't be trusted. I have seen total fabrications made inside the effin CERN for political reasons, stuff that makes you radically change your opinion on many, many things. You can't trust raw data, let alone deductive reasoning. At this point, my interest in debating the topic is shrinking more than the ozone hole. The real question is not how climate change. But why should I care? Let's see how rational you really are.

[@ssssyther]

@@VetruvianFebio Are you seriously asking for a reason to care that the planet remains habitable to our species?

[@VetruvianFebio]

​@@ssssyther Yes, why should I care about the earth habitat if I'm going to die in a bunch of years. Why should I damage and hinder my own short existence, that will end up into nothingness, for the future of a planet that is going to be engulfed and atomized by the red sun? Can you find a rational and logical justification for me to care about a future where I will not exist? There is no god, there is no meaning, you are just atoms and so will be the people in the future, nothing of this has an implicit value.

[@Burbituate]

@@VetruvianFebio Because it's not all about you...care to explain how "just atoms" became self aware? Reductionism to absurdism.

[@VetruvianFebio]

@@Burbituate Well, if it's not about me, why it's about you? Why are you important. Why are you more important than me. You are just chemical reactions that happen to be self-aware, according to our current arrogant concept of awareness. You are nothing more than a flame that learned to walk instead of relying on the wind. You use hands instead of sparkles to reach more resources but in the end, the point is the same, keeping the fire burning. This is the only reason why nature invented you, carbon oxidation. Is a flame important? are one million of future flames more important than one? All your moral values are meaningless cultural products inherited from some kind of evolutive advantage. They are all based on nothing but arbitrary opinions that change in space and time. Caring about the future is just another godless religion, an attempt to give you a meaning that you don't really have. And look, they are taking down Lincoln statues, the people of the future are not even going to like you. So, do you have a logical reason to care about climate change? You are just talking about an emotional attachment to a human species, for no rational reason.
