Another fun climate change thread

Fuck yeah buy a people mover and be the über party bus. yeah nah fuck that. But in theory it's cool like if somebody else did it.

 

Have someone get a bus and paint it like the Further Bus that the Merry Pranksters used to trek across the US.

 

I'd chill on it and smoke some doobies.

 

Isn't carpooling a thing over there? Here you can regularly spot a parking 'lot' for carpooling only. They're even used! (and they're next to the road (highway usually) and not near any destination so not likely they get used wrongly

 

Not sure if joking or aiming to make a serious point... or both

 

Well I kind of laughed at it originally... But then I thought.. That's exactly the kind of control and manipulation that would be bestowed upon us. And then I kind of probably looked like this.

 

Older folk here the word carpooling, theyll think you mean like in Seinfeld, organizing with friends to share a car to work.

You mean those rental cars already on the side of the road you just use a swipe card to get into. Car sharing, we have them here, they didnt really take off like I thought they would. I have an account with goget. Pretty cheap, $12.50 an hour.

Still, they started out being everywhere, but now most of them seemed to have disappeared.

Same with the bicycles you scan with your mobile to unlock, most of them seemed to have vanished

Even Uber itself didnt seem to have the impact many thought it would, there are still plenty if taxis around

Im afraid most people dont give a shit, they want to be alone in their own cars, or just stick their hand out and hail a taxi rather than stuff around with an app

Again, I myself am not being negative, just reporting reality. Uber was supposed to wipe out the taxi industry, what is it, 6 years later, still a shitload of taxis everywhere, the taxi ranks full when I leave work.

Why Im sceptical about self driving cars if they ever see the light of day, not that I think they are even going to be possible for a long ling time, but when/if they do. People just want to drive their own cars

 

This from New Scientist magazine this month

Its not from any climate change denial site



Antarctic sea ice is declining dramatically and we don’t know why

 

I guess if its laying there and will be cleaned up shortly it would be stupid NOT to use it as a trash bin

July 2019: A "NASA backed" study says The Thwaites glacier in Antartica will cause a half metre sea level rise.

'World's most dangerous glacier' half as big as UK could collapse drowning low-lying coasts, Nasa warns


"Antarctica's Thwaites Glacier is now approaching a "tipping point" that would spark an unstoppable flow of ice into the ocean" Unstoppable I tell you!!


"The situation is so bad that it could happen even under present-day ice-melting rates"

So, the situation is so bad it could happen

"And once the "instability" begins, nothing could prevent the ice from melting completely – potentially drowning some low-lying areas of coastline."

Nothing could prevent it from melting.....well except the sub zero temperatures


"After reaching the tipping point, Thwaites Glacier could lose all of its ice in a period of 150 years," warned Nasa JPL scientist Helene Seroussi"

It will take 150 years to melt apparently. Folks at the Jet Propulsion Laboratory seemingly taking a holiday from working out how to propel jets and are now working on how long it takes ice to melt

 

And the actual report


Marine ice sheet instability amplifies and skews uncertainty in projections of future sea-level rise

Which contains this chestnut:

"framework explaining the role of ice sheet dynamics in setting the amount and structure of uncertainty in sea-level rise projections. We provide such a theoretical framework in this study and find that ice sheet instabilities are amplifiers of uncertainty, which is a common mathematical property of unstable nonlinear systems (22). "

No study previously could get sea level predictions right, according to them, but they alone had worked out a way

Hallelujah!!!

 

Stochastic just means too random to predict, and perturbation theory just means approximating a more complex system from a simpler one.

And a gaussian distribution is an approvimation in itself

The paper isnt complete in the first place, there is no explanation of this magical time series.

Just seemingly one equation, the dL/dt one which is change in length = averaged snow falling on the glacier × thickness of glacier x length - minus ice leaving the glacier ( which contains a variable of the ratio of sea water to fresh water) - how much the ground under it moves (which includes their little time correlation magic they dont explain)

And then after all that. We get metres per year to only 2 decimal places.

ISSM isnt state of the art either, open source, written in python, its been around for at least 15 years, which means it was in development for 10 years before that

This is a summary from the previous thing published with ISSM, sea level rise predictions for various experiments im millimetres over 100 years




That paper a couple posts above, it is obfuscated on purpose, so news sources in particular dont delve to deeply.

If the solution contained within so magical, then no one else ever need to try another method, thus every other researcher is out of a job.

Another very important point is at least one of the researchers who wrote the paper is quoted in the media as saying something like - could raise sea levels by 1/2 metre, but it isnt in the actual paper, because they are not prepared to do it professionally.

Other than that. If it is such an important topic. Ask yourself, why isnt there a simple english version for the masses

The reason is, the simpler its explained, the more apparent it is, they are just guessing


Not that I think there are enough people that give a shit anyway

 

All that, and yet we get metres per year to only two decimal places. That metres, not millimetres.

I am saying salt to freshwater ratio at every point in time, the amount the ground will recede, the amount ice in the ground. These are all things impossible to work out

Conspirying to decieve us noo. Bullshitting to hang on to their jobs, hell yes

 

The Antartic Mainland at the moment, there is only one spot that every gets over 0 C and even then barely for one month in summer, the tip of the north peninsula

 

Why is it so damn hard to find a picture of this thing from 40 years ago?
