Global Warming & Climate Change Discussion

[Caring1]

Now if there were only a way to remove CO2 from the air that could be run off of personal exercise equipment during a persons workout.

It's called a plastic bag, tied over the persons head to capture the CO2, it can then be repurposed.

I was thinking of something that might be a little less of a safety hazard.

And just so we're on the same page, all of this began because I questioned the idea that majority consensus validates a theory. That's it, there should have been nothing outrageous about that but somehow I managed to trigger the lot of you.

I went into that at length just now, and explained in detail where that 'trigger' came from because saying one thing implicitly means another when you place that 'question' within a discussion like this - and if it doesn't, then you should just not say it, or provide substance to make it worthwhile. Its pretty strange 'all of us' have that same response to you, isn't it? But certainly, the world is crazy and Vya is seeing things right Your simple question was answered. You just didn't like the answer. That is all this is. Its really not about climate, but about you now.

But luckily you've surrounded yourself with a fantastic group of peers by now, real scientists and critical thinkers and all

Boy I am glad I stopped reading this thread, here I can help all of you.

Do what you can on your end to help the environment, and those that will refuse to believe or care about any of it will continue to do so, so ignore them and go enjoy your life.

I just made a 100 page long thread into one sentence. ez pz. time to game for me

This is the sort of discussion you get when all talking points have in fact been agreed upon. We try to find disagreement regardless, because otherwise we'd actually have to start doing something. Planning is great fun. Execution however... And this topic is just a tiny version of that inaction. And while I get what you're saying, 'do what you can on your end' is basically what we've done so far. It didn't really amount to much. Yes, we can do some recycling around the home, but when the economy isn't circular and until there is an outlook on how to turn growth into sustainability, its a pointless exercise really.

Actually GR can model a universe that is accelerating,

No it can't.

ironically, Einstein himself hated that when he added the cosmological constant because he was looking to make the universe static.

I think you misunderstand what Einstein was aiming for.

 

[Shrek]

Vya Domus has it right

General Relativity can model an accelerating Universe using a Cosmological constant; but Einstein introduced it for other reasons, namely to try and get a static Universe that Eddington then showed was unstable and so would not remain static.

 

[Vya Domus]

No it can't.

I think you misunderstand what Einstein was aiming for.

"Einstein thought the universe was static, so he added this new term to stop the expansion. Friedmann, a Russian mathematician, realized that this was an unstable fix, like balancing a pencil on its point, and proposed an expanding universe model"

[lexluthermiester]

Actually GR can model an accelerating Universe with a Cosmological constant

Well sure, IF you change a few variables that would then be incorrect, yes G&SR can model an expanding & accelerating Universe. But then the model isn't accurate which defeats the purpose and goal of the theory, to model the Universe accurately.

Thank You for proving my point. Also, see Edwin Hubble.

 

[Vya Domus]

Thank You for proving my point.

You don't need to thank me because you made no point as such, just that you said GR can't model an accelerating universe, which it can.

 

[A Computer Guy]

... Its pretty strange 'all of us' have that same response to you, isn't it? ....

I don't agree with this consensus as I am triggered for other reasons.

 

[lexluthermiester]

You don't need to thank me because you made no point as such, just that you said GR can't model an accelerating universe, which it can.

But only if you break physics. That's the point.

 

[Vya Domus]

Huh ?

I thought it was Eddington that pointed out the instability.

But only if you break physics. That's the point.

Not at all, the Cosmological constant was the only modification allowed without breaking general relativity.

 

[Vya Domus]

I thought it was Eddington that pointed out the instability.

I actually thought it was Lemaitre, anyway, I think a lot of people must have noticed that his solution was numerical unstable.

I would hate to give credit to the wrong person.

^^ A whole lotta OT. I only went back one page.

Please, stay on topic. And no more personal arguments.

I'm quite sad tonight... lot of birds are dying in my state... at least 700 so far... probably a lot more than that though, scientists don't why... same disease that hit the west coast birds earlier in the year... I notice even when I bike ride to the pond, there are no more geese and ducks... and in years past there were always geese and ducks... :/ The world is truly ending I feel like sometimes. I have a feeling it is all because of human hubris... I wouldn't be surprised if this new bird disease is related to covid in some way.

Crushing heat wave in Pacific Northwest and Canada cooked shellfish alive by the millions​

and yet, no governments have announced an end to cryptocurrency mining... bitcoin and the 5000 other coins are easily using 10-20 countries worth of electricity, carbon output that was never there before, added suddenly overnight in the geologic timescale... sure there are a lot of other problems for climate, but that is not a defense for adding more coal to the fire so to speak.

I read today that 350 billion dollars is being invested in new green friendly cement production for industry RND... hopefully something comes of that, but I fear its to late.

Right?

something funny has been happening here in south wales but its not bad, when we first moved into this house 30 years ago we had thrushes nesting in one of our air vents on the side of the house. we would get some years one brood of chicks and maybe 2 broods on a good year now for the past 4 outa 5 years we had 4 lots of chicks and this year we have had 5 so far. thay start nesting realy early now and carry on right into late summer maybe this is due to globle warming but the thrushes like it and so do the slugs and snails the thrushes feed on.

 

[Space Lynx]

Right?

in another article about the clams dying off, the heat was so severe even further inland in west canada, that some salmon died from the heat...

I read it was 125 faren in some places... :/ scary as crap... even further inland like in Saskatchewan Canada it was hitting 111-115 last week... not just record breaker temps, like wave above the previous record...

Fun times await us. Hope people keep enjoying their crypto, hope industry keeps enjoying pouring their concrete, hope humans keep enjoying their endless hedonistic pleasures... mother nature will balance it all out, and remind us who is boss soon enough. No doubt about it.

We have def messed up the environment beyond a point of no return... the rapid melting of Greenland is also rather frightening... I expect we will see world collapse of economies and the only food distribution you will get will be from the military of whatever country you happen to live in, probably rationed heavily as crop failure will happen in mass, etc. Hell, the ripple effects from the entire crustacean population basically dying overnight across the entire west coast of Canada will probably have enough ripple effects in the cycle of life... well I am tired of typing... goodnight.

yep mother nature has a lot of ways of dealing with over population, this covid is nothing to what she can throw at us and i dont blame her. on a side note being a astronomer for over 50 years when i first started in 1970 i could see colour in the orion nebula "blue and red"just with my eyes but slowly over the years it turn gray now with this virus and the flights stopping this last january the colour was back not as strong "but that could be to my old eyes""as in my youth but never the less it was back.

Recent articles confirmed that Polar caps are getting warmer on average.

Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)

Antarctica Melts Under Its Hottest Days on Record

Ice caps and glaciers felt the heat as temperatures reached 18.3°C (64.9°F).

There was an unconfirmed 100F near the Arctic ( northern pole ), cant find a decent source for that.

Yeah, I remember reading about that too. it's happening faster than anyone thought, the Canadian permafrost melted 70 years earlier than they initially calculated. this was in 2018 or something

Scientists amazed as Canadian permafrost thaws 70 years early

Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.

let's just hope it's not like the movie The Day After Tomorrow...

it's not just you, the Astronaut Mark Kelly when living on International Space Station said the most scary thing was how the atmosphere looked so thin and so sickly...

I'm afraid we as humans keep playing this game of oh we can change some things by 2030, or 2050... and the math simply doesn't work that. If we all stopped using are cars except essential personnel, shut off all electricity across the world, went back to local village lives... and we did it overnight, it probably still wouldn't be enough to reverse the damage done... I think it's all over personally. for humans anyway, Mother Earth will be just fine as soon as she teaches us her lesson she plans to do so very soon.

We are fubar, we just convince ourselves we are not, or that we can fix it. Mostly caused by greed, stupidity, and narrow mindedness. Shame oil is still black gold, still so much money in it, there is no incentive to switch faster to EV's, greedy oil producers won't allow it, they'll keep sucking away at it till it's gone and they have no choice. There is so much made from tax on fuel, why would most countrys just drop it, there's no massive tax income from EV. we are fucked imo.

I saw/read something ages ago that said the western states in America are gonna end up unpopulated deserts, unfortunately looks like it will come true.
