The very bad math drying up the Colorado River

California and Arizona are currently fighting each other over water. But this isn’t new - it’s actually been going on for over 100 years. At one point, the states literally went to war about it. The problem comes down to some really bad math from 1922. To some extent, the crisis can be blamed on climate change. The West is in the middle of a once-in-a-millennium drought. As temperatures rise, t...

Electric bike sales are booming. In the United States, retailers more than doubled their sales in 2020 and demand has only increased. Globally, we’re expected to reach 40 million e-bikes sold in the year 2023. It’s easy to see why. On the spectrum of transportation options, e-bikes have some clear benefits: They use a great deal less energy (and therefore cost less) than a personal car. They sa...
How snow loss is fueling the West’s megadrought

Lake Mead is America’s largest reservoir, supplying water for 25 million people across the southwest. It’s also drying up - a kind of poster child for the ongoing drought in the West. But upstream, a much larger but lesser known source of stored water is also disappearing: mountain snow. This is how climate change is throwing one of the United States’ most critical sources of water out of whack...

The climate tipping points that could change the Earth forever
Photosynthesis does not have a problem, it’s purposely inefficient in order to prevent too much oxygen in the atmosphere. One must always remember to take ecology into account
Excellent explanation. We have to know this.
Good video. Pity about the comments section.
Lead are good but mebrane with liquide and air ground😂
Amazing video! Thanks for making this. Regards from a cat that sings biology songs :)
Stop blocking the sun with sulfur sprays.
Maybe part of climate change is due to poor land management and not as much carbon. We need beavers.
Shut off the water to California and all the electricity!!! Also cut off all the water to las Vegas Nevada!! We need food, not gambling and hookers!!
heh heh robby just be like this'll leed to more research - not quite line with the videos very optimistic narative
I wouldnt be surprised if in a thousand years this place has developed a new chemical like when animals came about there was an evolutionary change with a very small organism which killed off most of the life at that time and it just happened again.
Before that it was plants and most life died then too before plants... same thing...
compliance due to convenience is not the answer
Hey it worked fine, who tf thinks hey if we tear down the tree and pave the ground we could build a facility to grow meat tf you mean a field dumb mfs
I love CAM. If purselane can survive a drought in a crack in the sidewalk, it is clearly the superior plant.
Gain of function, baby!
Preconceived notions are not helpful and there are a couple of classic examples of this in interplanetary exploration. Probes have have shown that atmospheric carbon dioxide levels on Venus (96.5%) and Mars (96.0%) could not have been caused by the burning of 'fossil' fuels. Furthermore, we must ask: just how prevalent is atmospheric methane in our solar system? Earth …….. 2 ppm (parts per million) Jupiter ….. 3,000 ppm Saturn ..… 4,000 ppm Neptune .. 15,000 ppm Uranus …. 23,000 ppm Saturn's moon, Titan, hosts gigantic lakes brimming with liquid methane, constantly replenished by methane rain. Methane is not a 'fossil fuel' and is not biogenic in origin. What's the point of the NASA space program if its results are simply ignored? But wait! What about this well=documented association? Jupiter 0.3% methane ; 10% helium Saturn 0.4% “ ; 3% “ Uranus 2.3% “ ; 15% “ Neptune 1.5% “ ; 19% “ Earth 0.002% “ ; 0.005% “
I'm totally about exploring technological options to expand energy efficiency in our food chains, but I'm super concerned about our food supply becoming more and more largely dependent upon patented foods rather than unpatented nature. Corporations will have an even greater chokehold on people.
All these people who has never driven a electric car in their life in the comments. You guys really need to do some research about battery degradation. I’ve seen enough electric cars over 100k+ miles on them to trust them. A battery is considered “degraded” once it drops to %70-80 of its original capacity. The car doesn’t just stop working. If you have a car with say a 400 mile range it would still have 300 miles of range if it can still hold %75 state of charge ( all battery electric EVs have a 8 year 100k mile battery warranty minimum). Matter of fact other than the battery, EVs are like ridiculously reliable. You could easily take an EV a million miles without having to do any major maintenance other than the battery. That being said yes battery replacements are like $20,000, I’d rather pay for that than a brand new car though. Depending how bad rust is in your area that may be worth it for the majority of people.
New Orleans sinking. Sea is rising. If you are not an idiot!!! You leave at the firt possibility!!! For your children sake. The city will sink in loan too to try to do something!!!
So, why doesn't California build a series of desalinization plants along the coast so they can make fresh water out of the Pacific Ocean? Then - California would possibly have plenty of fresh water and perhaps even have more than enough to sell to Nevada and Arizona.
Great one more reason why I hate summer thank you science.
Oh all these billions-of-years people want us all to be obese eating nothing but HIGH CARB veggies. *Fail.*
i think the next one should be called "TwoBisco"
OK komrade
That doesn't solve the real issue, the evolution of human which has already been failed, and we build, think, do to fail. The problem is always elsewhere right. Hell is the future, get it on !
Man, this really throws a wrench in my plans to start selling Baby's First Cigarettes...
If you’re gunna compare rural American trains you have to compare them to rural Japanese trains. We have them beat there.
I love induction cooking... instantaneous response... and the sensors can really help. We need better sensors and TIMERS on each burner... like boil for 20 min... then reduce to a simmer... like a spagetti setting so you can throw the noodles in and walk away safely... and if it spills over on the surface... it lowers the heat by some amount and sends a network or bluetooth alert to check your stove.
State enforced poverty. There, that's the whole explanation.
As soon as I hear the words 'climate change' I stop watching.
I stopped at 0:28 cuz guy doesn't know what he's talking about. That's NOT what "decentralized" means; bitcoin does NOT avoid govt surveillance...it's not a privacy coin. Decentralized means no center (or person or govt) controls it.

BUILD A NEW DAM.
our leaders here in the city are amongst the most corrupt in the country and always have been.. sht still to this day new orleans has royal family influence from royal houses that still exist like the house of bourbon two sicilies for example, lead by prince carlo one of the heads of the black nobility roman bloodlines. not to mention we are mainly a catholic state hence we have parishes and not counties,the corrupt catholic church and jesuits sank its teeth heavily in new orleans, freemasons etc. ever since huey p long it hasnt stopped, from ray nagin to the current witch. New orleans will always be corrupt and if you speak to a real new orleanian who WAS THERE AND SURVIVED THE FLOODS.. it was blown up with dynamite, the levees. it was NOT hit by a barge like they said to cause all that damage. it was intentional to rebuild the projects into nicer housing than we have in suburbs and gentrify the city a bit, etc. they removed active gangs like the gotti boyz who were runnin wild in new orleans and another couple clicks related to original hot boyz og giggitys homie had a click the doonie boys i think. ALL THAT was fixed and the city improved on crime etc, projects were removed etc. wasnt on accident.
Make a video on permaculture plz
The Earth is not in a Climate crisis because of any human doing. It’s because our climate is cyclical.
That scares me because we are fighting so hard to get native plants spread back around and thriving, in larger more connected spaces. Its a major key in ecological restoration and *ending colonialism.* the US was a massive cultivated garden, and many places on the earth were that, producing food vastly more efficiently than our factory farms. We need to stop bulldozing vast swathes of land and then rebulldozing them and building massive mirrors on the surface of the earth (roads), digging out the water everywhere to feed plants that can't thrive on their own vs food crops that grow in active ecosystems, etc. The change is a paradigm shift from how we do things, and what I see when I see this is colonizing.
Since California is hit with mother nature rain and snow, they should dig more trenches or lake to save those overflow water. Stop fighting with the Colorado river.. Share the water and Cali must save those rain and snow melt.
Cold climate is worse. Go vegan to save planet
I also slow down and make more mistakes when it is hot. I should change my name to RuBisCo.
Making photosynthesis more efficient ... that is a pretty bad ideea. A very bad ideea. That will kill the plant, because it will dry up from inside. Because more photosynthesis means more WATER and CO2 are converted to sugars.
Why isn't there any efforts to model the structural properties of RuBisCO in order to create enzymes of a similar makeup? We've done this with antibiotics
Superior CO2 photosynthetic fixation was already engineered by Tobias Erb at the Max Planck Institute for Physics years ago as their synthetic biology CETCH cycle: ruclips.net/video/u1NBSBJRA3M/видео.html
Great words. This video deserves more reach.
Since the video never bothers to explain. RuBisCO appears to _increase_ in efficiency up to ~94°F. And then quickly fall to 50% efficiency ~104°F. I'm confused why the creator of the video feels like this is a problem. Isn't the average global temperature something like 60°F? Best I can tell, with current warming predictions, we'll actually be seeing an increase in RuBisCO's efficiency for the majority of places in the world, for the next _millenium._
great but is this fulfill our current energy demand...
the low fps is making me sick
Interesting. Not quite GM, but close. They testing on mice all the way?
I can't believe humans sometimes. How can it be that we are spending our time trying to chance a protein instead of actually reduce global warming that makes it less efficient and make a hundred of other things worse as well.
Neat-o. But... so many grammatical errors around the word "bacteria". Remember, "bacteria" is a plural count noun. That means it's referring to more than one of something. The singular is "bacterium". There is no such thing as "a bacteria", in the same way that there's no such thing as "a houses", or "a geese". Also, "There's" is used to talk about one thing. "There are" should be used to talk about many things.
