As far as I know valves were shut quickly. The big leak was a result of remaining gas (under pressure?) between the valves that could escape. It was a lot, as the pipes run for 100s of km under the sea, so even with valves shut there was just a lot gas in the pipe.
Gasp! Oh no! Scientists are STUNNED IN DISBELIEVE! You won’t believe what they ALARMINGLY discovered! /s
The nearly 3 million rivers that weave across the world are experiencing rapid and surprising changes, with potentially drastic implications for everything from drinking water supplies to flood risks, according to a new study.
Nearly half of the world’s largest downstream rivers — 44% — saw a drop in the amount of water flowing through them each year.
Gleason’s conclusion: “Holy cow, the rivers of the world are a lot different than we thought.” Some are changing by 5% or 10% a year, the report found. “That’s rapid, rapid change,” he said.
Polluting - I don’t think so, except they’re 2 stroke engines, which are rare, nowadays. These days you see even more and more electric bikes.
Inefficient - People often go 2, 3, 4 people on a bike that uses maybe 3 l/100km (78 MPG) or pull trailers wich stuff loaded, while using less space than a car.
Unsafe - totally less safe for the people on the vehicle. I don’t know about pedestrians. However, a lot of the accidents happen, because poor education to get the license, if any; hardly any law enforcement and poor vehicle maintenance.
Noisy - not more than a ICE car. Some motorbikes here have broken exhausts, which make them noisy, but that again is a lacking law enforcement and maintenance issue.
I am aware, however, that driving 2 wheel vehicles in ice and snow is not a wise idea, so while it works in SEA, it would be different in colder climates.
I somehow doubt they would have less particles from friction. They usually use a cushion which touches the ground.
The imagination of a busy intersection with common people driving hovercrafts is funny, though. Or imagine driving on slopes.
People won’t like it, but 2°C is dying somewhere remote and the ambulance hasn’t been called yet. Even if doctors were around now, it’s unsure if it could be saved.
As John Schellnhuber, one of the biggest European climate scientists that has been part of the majority of IPCCs, said last year about COP:
“Wenn die Länder die Klimaziele nicht umsetzen, sind diese Konferenzen nur Jahrmärkte der Eitelkeit.”
Translation by Google:
“If countries do not implement the climate targets, these conferences will be nothing more than vanity fairs.”
Interview, where he said it, and also said that 3 degrees above pre industrial would mean the end of modern human civilization (in German):
Wait, wtf? Mouth dry! Mouth dry!
I actually watched that episode last night, so that post was kinda jumping at me. What are the odds…
Sagan, a real teacher. Not only smart, there are quite a few smart people. But also able to make something complicated easily understood. To make something abstract sound straight. To make something minds can’t grasp comprehensible. A beautiful ability!
One of those articles that make you feel disgusted about the world we live in.
Thank you to all those scientists trying to throw the rudder around, that get bullied, while trying to save fellow humans.
As far as I understood, it’ll leak into the atmosphere, where it’ll cause 80 or 100 times more warming than CO² for a decade or so, before breaking down into good, old CO², causing further warming for centuries / millennia.
Not sure, but I think I’ve also read that in the process of breaking down into CO², the ozone layer gets damaged.
But if CCS operations leak, they can pose significant risks to water resources. That’s because pressurized CO2 stored underground can escape or propel brine trapped in the saline reservoirs typically used for permanent storage. The leaks can lead to heavy metal contamination and potentially lower pH levels, all of which can make drinking water undrinkable.
Can someone explain this to me in a easy way?
As a layman I would be worried of large amounts of CO² suddenly leaking near where people live. But how does it make water undrinkable? I thought some people like their drinks with CO². And where do the heavy metals come from?
I recently read somewhere that it’s actually just very few bee species that die after stinging, among them honeybees. They have a barbed stinger that gets stuck while most bees have flat stingers and can sting repeatedly.
Read the Wiki and well, I dont know. It may be a climate agenda, but in my opinion being green isn’t necessary being bold.
Bold would be meeting at least what scientist recommend: halving emissions by 2030. I know, that’s very much to ask for any country in the world. That’s why it’s called bold.
What green parties all over the world are doing is: turn the rudder away from fossil fuels towards renewable energy. Which is a step in the right direction, but I think that’s not bold. It’s the least one can do.
Who are these candidates with a “bold climate agenda”? I don’t know any political party in any country, where I’d say ‘they’ve got a bold climate agenda’.
Regarding solar electricity: does that mean to mirror the sunlight to a solar panel? If so: ignoring, that one would constantly need to adapt the mirror’s position, I think I also read somewhere that solar panels decrease efficiency with heat. So my question is: could one increase solar panel output by bundling light or would heat related inefficiency cancel that out?
I don’t know where you live. But where I live, styrofoam costs next to nothing. In fact, you get it for free, if you don’t mind looking through another man’s trash. You can also probably get some for free if you ask a company, that gets stuff sent, that need cooling. Like a supermarket.
For environment: styrofoam is a kind of plastic, so there is that. On the plus side, it’s quite little plastic inflated with air.
I assume it’s way better than getting a replacement fridge, especially considering the electronics and maybe the coolant gas (I don’t know if that’s still an issue).
I wouldn’t be surprised if the electricity saved alone offsets the environment damage (assuming not fully green power used to run the fridge).
It’s not any snake, but some species that are adapted to living on trees. It’s also not really flying. Gliding would describe what they do better. As they jump, they flatten their body and make slither movements through the air, gliding maybe at a 45 angle downwards.
I wish I had been old enough during the time we could’ve still made changes to make a difference.
Why? When you cared back then the frustration must have been at least the same it is now. The hope might have been bigger, but at the same time, you would have been part of a very small minority. And I think it would have been hard to endure that almost nobody you know thinks similarly. You might have been the only doomer they know. And how fast we manage to screw up our planet, you would have likely gotten old enough to come to the same conclusion you came to now: we won’t make it.
I assume that the submarine producer gives stats like empty weight from which the current weight can be calculated.
However, weight isn’t the important thing in a sub. It’s the weight to volume ratio, or buoyancy.
A sub sinks when buoyancy is negative and rises if the buoyancy is positive.
There are three common ways to achieve the changing buoyancy: the most simple one is a vessel with positive buoyancy adding droppable weights until the buoyancy is negative.
Other ways are a neutral buoyancy vessel that uses it’s engine power to push itself up or down. Or a vessel that can change it’s buoyancy by filling up tanks with water (to reduce buoyancy below neutral) and blow them out with air or other gases lighter than water (to raise buoyancy above neutral). A combination of several methods is also possible.
So that’s about 13,000 homo sapiens mothers?
