My name is Simon and I make videos to improve your climate literacy.
In particular I focus on the physical Earth system, and how the atmosphere, climate, and climate change intersects with our lives. Sometimes I even try to be funny.
Since completing my PhD in atmospheric physics at the University of Exeter, this has been my full time job. I also stream on Twitch, host the How To Make A Science Video podcast, and wrote a book!

I've got a trailer, I put the kids in it. Game changer... In the spring/summer I don't use the car for any trip sub 20 miles
People are so trained to get everything made for them commercially, that they have become as knowledgeable than little babies in kitchen. Many of these products or something like them you can make from scratch yourself and also with fraction of money. That will never happen with meat, dairy or eggs. To make those from scratch you always need readiness to accept corruption, lies and cruelty. We can do more always and evolve but even face meats are much better for the world. We will become eventually more honest and honorable, when we start to respect lives of nonhumans. Unfortunately rich landowners don't give up easily from their pocket money from sweat of taxpayers backs never mind power that comes with corrupted system that favors them.
There is more to animal agriculture. Water use, dead zones in the oceans, health impact, pandemics etc. ❤
There will be a ice age.
You can also pass with no corrections ….
Adding onto the topic if cost at around 20min, you would be surprised at how heavily certain foods like meat are subsidised. If the gov isnt paying farms to produce meat then those farms need to increase their prices to survive. Likewise if those fake meats were subsidizes then it would be more affordable. I dont think everyone will be vegetarian/vegan i do think when govs change what they subsidise that we will see a big shift as "real meat" will become too expensive to be an every day product like it is now in the west as it would struggle to compete with the sibsidised mock meats (basically the inverse of what we have now).

in many cases the evidence isn't stronger, the complex is captured, the funding is better...
Uh, the 'days' on Venus are several earth-months in duration, so that should allow the dark side to cool down while the sun isn't shining on it. Why then is the night time temperature the same as the daytime temperature...? It's not the greenhouse effect, but rather due to the atmospheric pressure.
Always finding a new way to greenwash coal. Just let it go.
i just wish i could get the leader of my government to listen to you
I'm avoiding converting mine tbh, too many are a fire risk, besides they will tax it eventually
This video is false information. There's absolutely no good news about climate change. Global warming is not a good thing. Environmental pollution is really bad. The Holocene mass extinction of all life on planet Earth is catastrophic. Its all really really bad news. Like totally.
the graph of coal usage with china on it is just... why is there so much fuss about the UK opening One coal mine for coking coal. truely just mad times of delusions of grandeur that we're somehow a big polluter when really we could put the economy just that bit more first to enable the green transition, on-shoring steel reduces shipping, allows for cheaper wind turbines, etc
most people are suffering from excess protein intake. i.e. all this talk of "protein protein where we will get protein" is utter nonsense. especially since protein block starts from information that globally we get most of proteins from plants and some countries get all proteins from plants, i.e. animals are not needed as protein source. and that it's much more expensive protein source than plants, since animal protein intake scales with income
Been watching this PhD series since high school in 2018 . Now I'm a working professional as a physics major and I still watch this playlist. Something comforting to watch the week in the life of a physics student battling equations and inversions before AI could do it all for you.
Governments are going to pass draconian laws restricting energy usage for the masses. The problem is that the reason why they'll pass these laws isn't to prevent global warming but to monopolize energy. For instance, municipalities across the country are outlawing gas stoves and the federal government is forcing car companies to pivot to EVs. The federal government isn't, however, passing legislation restricting the sale of private jets. Worldwide, no government is passing legislation against the building, purchasing, and use of superyachts, which dump an average of 500 gallons of gasoline into our oceans every hour. We will always have oil and gas. What's happening is that the elites are consolidating the use of this energy source. Let's play this game theory out further. All vehicles will soon monitor your distance travelled. You will then be allotted a fixed number of miles per day, week, and year. When you travel beyond your allotment you will be taxed, meanwhile elites on private jets and superyachts will have no restrictions. "Global warming" will be the excuse that elites use to monopolize energy and control the masses.
Every time someone is enthusiastic about nuclear power, it's either some TED-talker going on about "Let's make backyard reactors in India!" (obvious security risk), or silicon valley nerds talking about how safe fusion energy is (once we invent it). You can't halt my knee-jerk reaction about nuclear until you demonstrate how we're going to phase-out the Chernobyl/Fukushima generation of plants (dismantle them), and haul in the fusion reactors.
20,000 years ago we were at glacial maximum.
I have done research on this topic recently for a short lecture I gave at my university. Its not entirely clear cut as you mentioned it is location dependant. On battery manufacture, if you make the batteries using recycled materials like the lithium, cobalt etc you get a cost reduction of 30%. There is a paper I used that was looking at how people travel in Europe and it noted that if you cut out 1 car journey per day for 100 days you have a 1 ton of CO2 reduction per person. I would be careful with that Trex report until more data is available because they have a vested interest in selling bicycles and ebicycles. But yeah its dependant on the electricity mix of a country and the diet of the rider, for example someone in Poland would actually be doing more harm by using an ebicycle or EV in general compared to just an ICE car or standard bicycle.
I have been riding an e bike since 2004. I used them for a 20 mile return commute up and down hills to work, for cycle rides, for getting back up stream after kayak rides down river, usually for shopping. We now have a brilliant Buddy rider to carry our dog. I have had 4 ebikes in that time, and the batteries have done pretty well. I have had Wispers for the last 12 years. My models are not top of the range, but reliable and well supported by the company engineers. I love my ebike!
All tools at disposal will be required to clean the waste we are producing as a species.
Glaring omission: For tens of thousands of years the proxy data shows that CO2 level increases have lagged behind temperature increases by from 800 to several thousand years. Thus, rising temperatures cause an increase in CO2 levels. Most CO2 not locked up in plants, is in ocean water. Rising temperatures caused greater plant growth, and dying vegetation releases CO2, but the vast bulk of CO2 was released from the oceans when the water warmed.
When scientists and governments agree they're both lying to you.
Of cause global warming and climate change is a reality, there is too much evidence to deny this fact. Its also obvious that human being has something to do with it, and it is not helping that we have so many wars going on right now. We may be doomed, but that is not a certainty and its certainly not a argument for not doing something about it. It seems some of these people are so addicted to their lifestyle that they will find any excuse and reason not to do anything about it, if they can't not do anything about it by denying climate change, they will try not to do anything about it by claiming we are doomed and it doesn't make a difference. These are not really factual or reasonable arguments, its just a excuse not to do anything about it and be irresponsible and lazy, which is exactly the kind of attitude which got us into the mess to begin with.
We never hear the climate truths either , most still saying the 1.5 is still a thing ! And we still pinning faith on fairy tale co2 removal .
I don't deny climate change, you'd be stupid too, it happens with or without humans. But WaterWorld can't happen, all the ice has been gone in the past and the planet was very happy with lots of dry land, we just happened to build houses on the waterline lol.
im still amazed of people think how much humans impact the global temperature so much. Time to wake up people
Also skeptical science, it would have been nice if they disproved something in favour of climate change, the examples given all showed climate change is real or more dangerous than some people think
Why would oil companies want to hire climate scientists 😂 surly they would want geologists
First argument was very weak
The bad news: this video is 5 years old and the "Titanic Earth" is still sinking, now faster than ever.
The fluid dynamics of dihareah severity
Political "IRRESPONSIBILITY" by leaders everywhere has war Number One over ANY other ideas, so climate is also pushed aside as deals for more oil are signed.
scientific consensus? cringe.
Your short on the visualization of carbon emotions is misleading and you know it. What's worse is that you turned off the comments to hide for the peer review. How do you expect anyone to believe that Brazil has no carbon output? You sir have no shame.
I must be honest I was following you since 2016 stopped watching your videos after the pandemic because it effected my mental health very negatively (alongside other climate change related channels) but it's nice seeing that the nihilism I was going through was rootless, useless and counter effective.
This video highlights the typical monday morning quarterback approach. Sit back and put down those people and organizations that are actually doing something about the pollution. Just sit back and collect data for the next 50 years and see where it gets you. You are a disgrace.
You said that some denier claims are "readily disprovable." But so are yours. Every climate prediction from twenty and ten years ago has been wrong. Look around - there are plenty of polar bears, and the sea level rise hasn''t convinced every scientist.So much evidence can be looked at in many ways, depending on your view. Why did your side of the discussion cease to repeat that 97% of scientists agree on climate change? Because they don't. I'll change my mind about this when it is proven. It is not proven yet. kzread.info/dash/bejne/pox-mbeTmqmqeLg.html
Haven't really watched the whole video yet but have to disagree on two key points from the 1 minute mark. Cow burps shouldn't really be counted as net emissions because methane in time breaks down in to CO2 which gets converted in to feed for the cow. So the total methane content in the atmosphere doesn't increase. In the same vein plants don't really count as carbon sinks because they get eaten either by animals or by humans, or they rot and get converted in to CO2. Of course it's not that simple and animals do contribute a lot more that plants to emissions, but misconceptions like these skew the real picture too far towards plants.
The late Carl Sagan, if you listen to just the 1st 5 min of him talking, you will see the shame humanity now bares for what we have been allowing out of ignorance. It is no longer an excuse to be ignorant about what has happened, and that greedy humans continue the destruction at an accelerated rate. kzread.info/dash/bejne/iaRhucuHiKucmKyc.html
We tried flattening the curve once...
Wait so plants are getting fat?
3:50 lovely KZread video but we also need to consider: Water pollution (e.g. nitrogen runoff) Noise pollution Risk/cost to life To get a useful shortlist, which one selects by difficulty to farm in a given geography. Just going "carbon intensity" and "land size" we're inevitably going to find that farming animals is the worst, tech bros suck, and veganism is efficient - this has been proven time and again for decades
That is very nice. I wonder why you couldn't charge the battery, while going. It works fine on our bikes.
My mother was right. I should have learned how to read lol
Al Gore is a great con artist.
Im not an expert, but I think the way the motor disengages at 25kph is a little different from how youve shown it. I think there is a soft cap and a hard cap. The soft cap starts around 24-25kph, and it more restricts the max power output to a level that can maintain 24-25kph without exceeding it. And then a hard cap at 25kph where it actually shuts the motor off totally. So even if youre not cycling past 25kph, the motor is likely still working very hard.
Future climate modeling is NOT climate science. It's climate modeling.
