This is the story of how we discovered the planet was warming, and why. Learn the building blocks of climate science with Brilliant: www.brilliant.org/simonclark
The climate crisis is caused by a build up of carbon dioxide in the Earth's atmosphere, which traps energy and raises the planet's average temperature. This was discovered over the course of 200 years by a large cast of chemists, physicists, geologists, and other scientists. Some of them you may know, such as Joseph Fourier and Charles Keeling, but many of them are less well known. This video tells the remarkable story of men and women like Eunice Foote, Roger Revelle, Guy Callendar, and James Croll. But there's still more to be told! If you would like to see part 2 of the story, focusing on the 1970s, 80s, and 90s, let me know in the comments.

As so often in theories of people who propagate the co2 story, this promotion does not mention the (also by scientists) so-called Little Ice Age. A (with fluctuations) cool period of about 400 years, which ended about halfway through the 19th century. The glaciers in the Alps reached their maximum over a period of 3000 years in 1859. This study included several alpine glaciers and they all showed the same pattern. No wonder people began to experience the weather milder at the beginning of the 20th century. Since there were hardly any meteorological temperature measurements before the mid-19th century, these glaciers are very important proxy for an indication of the climate during the past 3000 years. The study also shows huge fluctuations over that 3,000-year period. The period about 2000 years ago during the Roman period is striking. A period of several centuries when the glaciers were so small and receded that they were virtually non-existent and therefore smaller than today. But during the Little Ice Age, Iceland was usually inaccessible to shipping during the winter months because it was surrounded by sea ice. The settlers in New England also had a hard time, because at that time frosts in June or July often destroyed the crops in the fields. This is known from chronicles of that time. The settlers could make do with hunting, which the common European people could not do, because here there was still a feudal system in which the people had to hand over the harvest to the elite. The common people could not/were not allowed to hunt, it was regarded as poaching. As a result, massive famine with attendant debilitation, disease, and early death. The average life expectancy in 1800 was 45 years. It is known from chronicles that children in the Alps began to eat grass out of sheer misery and hunger. It is widely believed that this miserable condition was part of the cause of the French Revolution. The Little Ice Age is, of course, not a true Ice Age. (but got that name) Nor the "past ice ages" mentioned in this video. These are glacials within the Ice Age. We are now in an interglacial in an ice age. Because as long as there are ice caps on Earth, we are still in an ice age.

@scallop640 Год назад

don't forget the mid evil warming period as well, which happened right before the little ice age. A period of time hotter than it is now, yet was also prosperous. I do believe C02 can be correlated to the warming of earth right now, but I also believe we could be missing other things contributing and don't have enough time to actually prove the theory that strictly gas emissions are to blame. Only time will tell I guess, it's also hard to not question science after seeing how money/corruption works in the field. The past 20 is years of Alzheimers research/data has found to have been fabricated.

@steveevans946 Год назад

Very well presented - thank you. I began to research the link between CO2 and temperature rise in the early nineties. At the time there were many detailed meteorological studies and studies of ice cores, which showed no link, at least at the scale of the atmosphere, between CO2 and temperature rise. If there were even a slight link, it was that temperature rise precedes an increase in CO2 levels over a period of 800 or so years. Sadly, the demonisation of CO2 has become dogma, and no debate is permitted. CO2 is a trace gas, 0.038% of the atmosphere. At this level, it cannot have any influence on global temperatures, I would argue (though it may be different in a vessel full of CO2, when heated). We must allow debate to resurface on this, because we're about to plunge ourselves into a dystopian future of restricted food, energy and consequent poor public health. After all, CO2 is plant food and for plants, 380 parts per million is pretty low - some argue practically starvation level. Science is a method of systematic observation of the real world in order to draw tentative conclusions, always allowing those conclusions to be scrutinised. Science is not an oracle of wisdom, but it's the best system we have and we shouldn't abuse it with crass assertions such as 'the science is setttled'. That should never be the case. Climates do change! 12,000 years ago, there was an ice age. Now there isn't (although the period we find ourselves in is called an interglacial, somewhat worryingly). That is a rather simple statement, but it is an observation and can be debated. We must not rush headlong in any direction (unless there's an asteroid headed our way!), lest we engender untold misery for little or no reason. We now have a new term - 'climate emergency'. Emergencies are a brilliant way to shut down debate. We have been presented with many questionable emergencies over the past 30 years and all have fizzled away to nothing, but have led to restrictions on our freedoms, if you think about it... This worries me far more than the latest worrying concern.

@skfalpink123 Год назад

The problem with much of the science around CO2 is that it has always failed to factor in biomass - and continues to do so. So ocean acidification will release CO2 back into the atmosphere, but at the same time Coccoliths will absorb that carbon (via algae) and concert it to calcite, which (in turn) is deposited on the seabed and eventually becomes chalk. Geological features like the chalk cliffs at Dover, were created as a direct consequence of the massive increases in CO2 levels at the end of the Cretaceous (caused by the eruption of the Deccan Traps in what is now India).

How come the heat absorbing capability of Atmospheric water is never discussed in these climate discussions? From my work with FTIR, I know atmospheric CO2 is heat absorbing but it has a very narrow absorption spectrum while atmospheric water vapor has a very wide and deep absorption spectrum that will engulf a CO2 peak.

@jakedenos Год назад

water vapor is also not limited to 400ppm but more like 10-50000ppm

@zalzalahbuttsaab Год назад

Yes water vapour is a major greenhouse gas. CO2 is a trope that doesn't really figure in the equation.

@thurbine2411 4 месяца назад

Oh but it is certainly discussed. Aircraft contrails is one of the more publicly known parts I would say. I also think that most of the water that we add to the atmosphere down at lower altitudes doesn’t stay for long at all and so the effect is quite limited compared to the co2 we are emitting. Still if we are talking overall temperature of the earth then I think water vapour is a much bigger contributor than CO2 but for the part that we humans have emitted and the part that has actually changed over the last century or so co2 is playing a bigger part

@gatorbna4107 2 месяца назад

@brucepeterson3246 Exactly! No one knows the feedback effect of water vapor. Also the self- proclaimed Oxford "expert" failed to mention the studies demonstrating that as CO2 in the atmosphere increases, the rate at which the additional delta of CO2 contributes to additional warming gets smaller.

There is a large body of scientists (they must not be government funded) that disagree with these conclusions on the basis of these points. First temperature measurement has significant inaccuracies that dwarf the claimed increases in temperatures (measuring devices / micro climates / methods of measurement / selection of measurement data to get included in the average). 2. The effectiveness of CO2 as a greenhouse gas. The models create estimates of that function, but that driver is created through the "observed" increases in temperatures. In other words the models are ordained with a predetermined conclusion that CO2 is the cause - but its effectiveness as a greenhouse gas on climate has never been demonstrated. 3. Climate Modeling is wholly inadequate and has not correctly predicted any change in climate. 4. Time windows are always picked that ignore massive previous shifts in earth temperatures warming and cooling where CO2 was not a factor. In other words warming/cooling has happened a lot in the past well before there was a human factor and the current warming if there is any is just a part of a longer term trend. Hot or Not: Steven Koonin is a good resource. PS NOTHING predicts a chatostraphic outcome in fact the UN Models predice worst case by the end of the century (75 years from now) a 3% impact to Global GDP. Intellect not emotion must be applied to this discussion and the fear mongoring must end.

I can’t believe that, until the 60s, no one had bothered to factor-in acid buffering. It’s such an important chemical property in so many industrial and biological processes. Also, if you did the math on ocean acidification sans buffering, the oceans would’ve been a pH of 5 in the 70s and 3 or 4 today, inhospitable to life. And the reverse would be true as well, lower CO2 in ice ages sans buffering would have resulted in inhospitably alkaline oceans. If they gave it even a shred of thought….

@gwalkeriq Год назад

With no CO2 in the atmosphere, ocean PH would be around 10 or 11 IIRC. Don't think we would care much since we would all be dead. The acid effect as well as the buffering in the ocean is vital for life, and not surprisingly in our blood too.

I absolutely loved this historical perspective. IMO this information is important to understand the present situation. I’m looking forward to the continuation of this video. Finally, concerning the aerosol masking effect, I understand that sulfur dioxide is not the only substance that causes aerosol masking. In addition to sulfur dioxide there are particulate emissions which are emitted mostly by combustion of diesel fuel. Some climate scientists believe that a sudden cessation all economic activities could give rise to a catastrophic increase of global temperatures by approximately 2°C within one or two months following the cessation of economic activity. Can you comment on this possibility. Thanks

@robertcartwright4374 Год назад

I'm not a scientist, but what you're talking about is how particulate matter introduced to the atmosphere by combustion has a net cooling effect, but only stays airborne for a few weeks, so if combustion were to stop the earth would lose that cooling effect in the same time frame. But don't forget the atmosphere and oceans are very massive, and would take decades to warm up and come into equilibrium, so global average temperatures would not so suddenly increase. I believe the estimates as to how much net cooling aerosols provide are uncertain, but in the range of .2C - .5C, rather than 2C.

No Simon, you are incorrect. The reason the Earth is at 15degC and not -16degC is because of the heat trapping properties of water vapor. While CO2 does trap some infrared, the level of CO2 in the atmosphere combined with the fact that water vapor traps a wider range of infrared radiation causes CO2 to be a quite minor contributor to the 'greenhouse effect'. Just take a look at the absopriton spectrum for each gas.

Jurassic period showed mostly continuous average global WARMER temperatures than todays'. 4. Jurassic period was at the end of Pangea breakup, (that's where the increase in carbon came from) where the surface area of the oceans was greater than today and their were no land masses at or near the poles, there was no ice at the poles and little if any "albedo" increase and although some evidence of ice is possible little formed to call it an "ice age" (sounds like you got this from a right-wing climate conspiracy deniers website?)

In the 60’s it was said that we were coming out of a mini ice age. Back in time there were far more serious ice ages. What caused these to disappear. Another interesting fact is ice cores from the Antarctic found tropical plants below the ice cap. Also, to what extent do the natural emissions of gases and pollutants from volcanic activity and forest fires have on the planet.

@markw4206 Год назад

LOL. Literally all of those issues are actually very well understood. We have pretty solid records of insolation over the decades (it's been DECREASING as the planet has been heating rapidly). The earth's orbit is very eccentric and varying, but that happens in well understood patterns that were characterized extensively in the mid 20th century by Milankovitch. It's the REASON we understand the ice age cycles. Long term climate change is understood via a variety of temperature proxies, and we also know what drove the changes. And volcanism's contribution also is well studied. For instance, all the volcanoes in the world release less than ONE PERCENT as much CO2 as humans do.

By huge measure water vapour is the most powerful greenhouse gas of all, causes variations in atmospheric temperature variations, but water vapour is a feedback, not a primary forcing, to a very good first approximation, because it rains out. The arithmetic sign of that feedback is positive, which makes it an amplifier. If only we could demonstrate water vapour feedback (to the forcing by noncondensing GHGs) with a negative sign.

Please include information on the Greenland ice cores. I’d like to see some sort of explanation for the massive variances in temperature that go back about 200,000 years.

With that, the magnetosphere is shifting which probably changes the way solar radiation is filtered. Please give this some consideration. Thanks.

@Stratosarge Год назад

You might've seen theories suggesting something like that, but that is unfortunately bunk. We know that the polar inversions and pole-shifts happen. Frequently even considering the geologic time. But there's no noticeable climate variance associated with those shifts and reversions. The massive variance happens due to changes in insolation due to the Milankovich cycles that triggers a glaciation or an interglacial. With the feedbacks from changes in earth's albedo and CO2 concentration amplifying the effect.

@easy_s3351 Год назад

Like Faro says, read up on the Milankovitch Cycles as they are the main forces behind the continues climate change that earth has been experiencing for hundreds of thousands of years. They explain the ice ages and interglacial periods. Also, take into consideration the increase in solar radiation over the last decades. Fun fact is that because of rising levels of CO2 and nitrogen in our atmosphere and the global warming, earth is now 15% greener than it was several decades ago.
