The world smells different now. That's a big problem.

The world has changed. I can smell it in the air. Learn more about the chemical processes underlying ocean acidification and smell with Brilliant: www.brilliant....
This video is about how mundane experiences will be different in a warmer world. You may already be aware that things like wildfires and droughts will become more common, but everyday experiences will also change. Food will taste different, tropical diseases will become more common, and the world will smell different. To us on the land and to creatures in the sea. This in itself is a problem, but its nothing compared to the biological implications of these changes.
This one's really depressing, sorry.

The world smells different thanks to climate change, with a rise in global temperatures and ocean acidification changing how the world smells. That means the scent molecules in the air and water have changed but also how we smell has changed. This science video essay talks about chemistry of smells as well as the biology of climate change and how a warmer world will smell different.

In the meantime, stinky candles, sprays, plug-ins & essential oils assault our senses. Fragrance goes beyond perfumes and is in EVERYTHING, overpowering our natural sensitivity to appreciate a single flower. Instead of making things smell "like" something, maybe just stop making those things go extinct. I love the smell of a pine forest, I don't need a candle or a cardboard tree in my car to mimic it.

[@NoXion100]

Those artificial pine-smelling cardboard tree things used to be massively popular because old cars stank to high heaven of oil and petrol and stale upholstery. I remember my mother used to drive an Austin Maxi and a Ford Capri, and each of those cars had a really strong mechanical smell of their own. Modern cars don't smell so strongly. Personally the mechanical smells of a car give me nostalgia, but I know that some people find them a bit sickening.

As a sensory science researcher with a focus on olfaction, this tickled all my science bones. I (and my entire team) usually focus on smell in human health, eating behavior and wellbeing (e.g., I'm currently working on a project researching long-term smell and taste loss after Covid-19 infection). I've never looked at smell in environmental terms in this manner - which makes sense as I am in nutrition science and not environmental/animal science - so this is incredibly interesting to me and something I will consider in my future as a researcher.

When they replaced all the deciduous forests with pines around my village, so many different smells just disappeared. It's all pine now. So many plants that grew near those trees have gone since those pines grow so quick and take up the sun all year round and nutrients. There's a lot fewer birds, squirrels, bees and deer now too. Haven't seen a badger since I was a kid. Even though it's on the village emblem, they pretty much made them extinct. Along with the vipers. Now I have to go through a 45m bikeride to find a native forest to get that scent I loved as a child. And even there I can't venture too deep not to disturb the few patches of wildlife we still have left...

[@YNajjar]

As a PhD student studying plants, I can relate to this a lot. I study how broccoli chemicals reduce cellular stress. The big problem is that the vegetables we eat are not as effective in fighting diseases due to their reduced production of the beneficial chemicals, which can be attributed to climate change and in addition to many factors too. At my lab, we grow our own broccoli plants under controlled optimum conditions. I assume that growing crop will be a challenge in the future, if not already. Although broccoli can tolerate harsh conditions, there is a limit to everything, and soon we might not be able to grow good quality food anymore. I think there should be more collaboration between scientists from different disciplines. We should sit down, with a cup of tea or coffee or whatever you like, and have a serious intellectual conversation. I mean, that would be so much fun too!!! Great video @Simon Clark! Love from Chicago!

[@leif1075]

I'm vaguely aware of how climate change and of course rising temperatures makenit harder for plants tom grow and tbrive simply because of excess heat and if not then wild temrpature fluctuations..but I'm curious as a specialist what have you learned beyond that exactly is it that contributes to hindering vegetable growth like broccoli or hinders or inhibits the reduced production of beneficial chemicals in broccoli or other veggies as you mentioned? Thanks for sharing your insight.

[@Jay_Johnson]

in reference to reduced production of the right chemicals why is that? can we not breed/modify them to do so or if not produce them synthetically?

[@YNajjar]

@@leif1075 Hi Leif, I welcome your question!

[@YNajjar]

@Leif: Although I’m not an expert in climate science, I can tell you that drastic changes in our climate is worrying. Although changes in temperature may have a significant effect on plants, change in climate can change other aspects of our ecosystem, or to be more specific, the microsystem of plants. The rate of Infection for example may rise due to change in climate. Plants rely on defense mechanisms to protect themselves from infection and cellular damage. Damage can come in the form of environmental ( UV radiation) or biological ( bacteria and viruses). So you can imagine if such defense mechanisms that play an important role in producing very important chemicals ( like the bitter sticky sap) due to significant disruption done by climate change and pollution, plants will struggle. This applies to growing our food. If broccoli or kale or any other veggies are not able to grow and produce a healthy amount of such good chemicals, we will be affected too because we will not be ingestion enough of the good nutrients to help us fight disease.

[@YNajjar]

@@Jay_Johnson Plants like us, share similar kind of cells. When we get sick, our body tries to fight the infection and luckily successfully does so. But sometimes it fails, that’s when we get more serious diseases. In plants, defense mechanisms prevent plants from getting “sick” too, but if these are disrupted, the cells will be overwhelmed with damage from sources such as too much UV radiation (will get worse due to climate change). Damage by UV causes an accumulation of factors that causes stress to cells. Plants overproduce defense chemicals to reduce the accumulation and heal the cells. But again, if that process is disrupted, then that’s not possible. Many have tried synthesizing such chemicals or at least extract them from plants. In fact, you can buy plant extract over the counter pills. The problem is that these pills are not as effective for many reasons. Second, we still don’t fully understand what these chemicals are doing in animals and us, as in the mechanisms. Until we know how they work in our body, we cannot synthesis the best chemicals for our own benefit, and we haven’t figured out the best way to produce these chemicals yet.

0:04 Using that line in the beginning from Galadriel is a very refreshing piece to include.

In Tolkien’s works, humans are significant in their ability to shape their own destinies, and shape the world in return. I really think that the usage of that line is a good representation of what we as humans have the power to change the world, both for better or worse.

I guess the most important thing to do with preserving smells is to go after the sort of smells that pollenators would be looking for.

[@Shivansh-qw5jl]

I think that when the poles melt the water spreads over the earth. Thus it must surely decrease the distance between the earth and sun by a insignificant amount for us but actually a significant amount for the other daily climate routines which is due to the spreading of water from poles evenly on the ocean layer the sun's gravitational effect on earth must increase on earth resulting in the phenomenon. [In short this is due to the change in earth' angular momentum and centripetal force acting on earth] I want to mention here the pollutive layer in the atmosphere must rise higher [including the differential density concepts of different components] due to oxygen layer reduction thus allowing the lower pollutive layer to rise much higher thereby depleting the last protective layer and hence helping more in the phenomenon. Which further rises the concept of 'dry rains' and 'dirty sponges[clouds]' I also want to add that it would then become difficult for the space communications systems also due to change in atmospheric density. layman astronomical persons can also add up that it will become difficult for the manned space missions as the return will become difficult due to overheating. Please correct me If I am wrong...

Ocean pH is measured as an average from several readings. Sensed odours are not averaged, changing from sniff to sniff. Your coffee loses its odour as soon as you taste the coffee. If the smell is unpleasant at point A, I can choose to move to a more pleasant spot B. It is one of the benefits of being motile, and a member of the animal kingdom. The "smells less" as climate changes as a speculation is an odd conclusion. More volatiles are released with rising temperatures, and would increase as the temperature rises. Scented candles and vaping, and back to freshly roast coffee as examples. My world has changed for the worse since Covid-19 changed my sense of smell, and not the miniscule change, up, or down in global temperatures, since the beginning of the pandemic.

Two things: nitrogen oxide and ozone are significantly lower now than have been for decades in western countries due to pollution regulation, and will further drop dramatically with electric cars.

Oh no. The prey not smelling predators because of ocean acidification is horse crap.

[@dnomyarnostaw]

And you have some studies for this?

[@iseriver3982]

@@dnomyarnostaw no, and that's the point. The studies about it were bad.

@@iseriver3982 Found it, thanks. I also found an expert panel discussion on the variance of results. The results are by no means invalidated, Titled "expert reaction to study looking at ocean acidification and coral reef fish behaviour" sciencemediacentre "“The inconsistencies in the evidence overall in this area do not justify the unambiguity of the paper’s title, that ‘ocean acidification does not impair the behaviour of coral reef fishes’. Indeed, in some of the experiments in this study, there were significant changes in fish responses. The authors also consider the results of previous work to have a probability of 0 out of 10,000 - that is either a typographical error or statistically meaningless." "“For these reasons, I think this paper is an interesting addition to the field but does not invalidate the significant body of research that have shown different results. The new work simply identifies the need to better understand the context of the experiments being conducted and that we should seek to identify the specific differences between the studies that could have led to these different results, to help increase the knowledge base of the current and potential impacts of environmental change across the world.”"

So how has the world managed to keep ticking through every other change in temp?

[@dnomyarnostaw]

It hasn't! For most of the changes, Humans weren't even on the Planet. For the others, well there have been about 4 major extinction events, and thousands of minor ones.

[@thelastdwemer]

@@dnomyarnostaw Do you have any good references for a mass extinction caused by a major warm period? I'm curious to know more about the topic.

[@dr.zoidberg8666]

Time tends to do that. The human-caused mass extinction will probably be like the others. After many millions of years, life will evolve to fill the niches that were emptied during the great die-off. That doesn't mean much to humans, though. Such timescales are well beyond us & might as well mean that these destructive changes are permanent from the human perspective.

[@camelopardalis84]

"We're destroying the planet" actually means "We destroy the planet as we know it: As this place where humans can live."

[@cgarzs]

That's a pity. But it's still better than paper straws.

Joke on you! After Covid i cant smell anything anyway

[@ElectricityTaster]

who knew all those cow farts would end up changing how the world smells.

[@Egilhelmson]

Eighty percent of the time since the Precambrian has been in a non-Ice Age environment, including most of the Cenozoic until the Pleistocene, about 2.6 million years ago. Expecting huge extinctions from what most genera would view as a Return To Normalcy is ridiculous.
