Global Climate Change Science News

[pErvinalia]

It's kind of ironic that capitalism is leading governments in change, given that capitalism got us in this mess in the first place.

They are using cold, clear logic and see the reality of the risks to their money if they continue with coal...

For Galacticus.

Oh dear, oh dear... I'll respond to your trite, just-so cliche.
Firstly, there's no such thing as 'better' or 'worse' science. Science is science; it's a system of thinking & analysis. If the 'scientist' is inept or a paid prostitute/hired-gun, then what they do is not science, it's something else. But Galaxian will humor you and reply to your assertions:
What refutes science?

That's easy, it's what you do all the time: SCIENTISM... the religion of dogmatists & bigots who feel empowered by riding on the coat-tails of notable scientists of the past, such as Galileo.

Speaking of whom we get to another refutation of science: The Inquisition. Recall that Galileo was tried for heresy and threatened with torture, and he capitulated and was put under house arrest till he died. In other words, his science was refuted successfully. And no one gave a damn. It's neither here nor there that eventually, in the fullness of time, years later his ideas are taken up and become fashionable (somewhat). He LOST, as did his science. Even to this day half the population thinks that the Sun goes around the Earth.

As Mao said, "Power comes out of the barrel of a gun!" The old consolation prize, "The pen is mightier than the sword" is just that; a sop to ease the pain of losing as you have the sword thrust through you. Yes, in the fullness of time things happen, but not because of the victory of the 'superior' science, but because of the winnowing out done by the Laws of Nature as it operates Natural Selection. THAT is why this is the last generation of the present species.

It follows that the rest of your gibberish, about "what doesn't refute science", is misconstrued. Because ALL those items (feelings, religion, favorite politician, half-baked opinions, and so forth) ALL refute science, especially if the science is disappeared or disapproved or disparaged or dismissed by the mass media, 'science' propagandists and forums & their members who are simply after the glitter and the instant orgasm, and are as impervious to any amount of evidence as a pile of dung...

You don't like people, do you?

[pErvinalia]

No YouTube video. We're making progress.

[Galaxian]

You don't like people, do you?

"...like people" does not compute. I'm 'happy' enough to have a laugh as much as the next sentient being. But the operative word is 'sentient'. The more the sentience of the being with whom I associate with, the more I 'like' it.

So, I don't enjoy buffoonery for its own sake. Watch the interminable adverts on TV... all having the time of their lives because of some trivial product. Or the injuries and desperation at the Black Friday sales. Or the lies perpetrated by the media, and no one is skeptical or vaguely curious, even when counter evidence is staring them in the face.

Yes, such a species has reached its "use by" date. There's NO WAY that ANY amount of education or training can take us past the impasse of our intellectual limit. Even now the progress we make is with the full cooperation of the computers that are so advanced that not even their so-called designers can understand the hardware or software.

For the past couple of decades design evidence that's not backed up by many pages of computer analysis is hardly worth presenting, because those who are supposed to approve it can NOT understand the methodology, design philosophy, or the calculations, and will argue and resist persuasion unless presented with computer graphs, diagrams, tables, and algorithms. Then they accept it; not because they understand the computer output, but because they can not understand it, but will not argue against it because it was done by a computer!

Thus we see that the species has reached its natural terminus. AI is already millions of times faster & better than us, and continues to progress at a prodigious rate. There's no reason why an inferior species should be preferred over a superior one.

"Global warming" is scary to right wing nationalists. Global implies the UN is involved.

Faster and better at what exactly?

Face it, AI continues to be a huge disappointment.

"Estimates of when the world will top safe CO2 levels have varied over time. A 2013 IPCC forecast said the 1.5° threshold could be breached as soon as 2021. In a 2018 report, the panel estimated that Paris commitments, even if followed by more stringent emissions reductions in 2030, won’t be sufficient to limit warming to 1.5°. Some studies suggest that existing emissions have already committed the world to a greater than 33% chance of 1.5° warming or more, whereas others suggest the world may have 20 more years at current emissions rates before blowing past the mark.

Bringing CO2 concentrations back to safe levels, many scientists believe, will require the extraction of a significant amount of CO2 from the atmosphere. There are two ways to mitigate CO2-caused warming: geoengineering to curb the amount of solar radiation reaching Earth’s surface, and removing excess CO2 from the atmosphere. Known as negative emissions technologies (NETs), the various methods that take the second approach form the subject of this article."

It is not exactly glamorous work. Measuring sheep farts is smelly, time consuming and expensive.
But for Dr Suzanne Rowe, a scientist who is breeding strains of sheep that emit less methane than regular flocks, there is nothing more important she feels she could be doing.
“New Zealand has really become a global leader in this space and there’s a lot of buzz around at the moment – it’s hugely exciting,” she says.

It would make more sense to remove CO2 at the source, since the concentration is higher and the economics of adsorption are better by some orders of magnitude.

...then again why do we need to add any extra CO2, at all?

CO2 could be a useful resource in storage of energy, and methane as a means of purifying water by clathrate formation.

--Jeopardy?
Face it, AI continues to be a huge disappointment.

Glad that you wish for AI to be even more effective.
Yes, it beat humans at Jeopardy almost a decade ago. Beat grandmasters at chess three decades ago. At Go a few years ago. Can now teach itself any game from scratch and beat the world champions with ease.

In technology matters; has been able to diagnose & recommend the treatment of any illness in a matter of seconds for the past five decades (progressively more so year by year), is used in all engineering design, such as structures, cars, trucks, ships & planes, that it designs within minutes, from the ground up, constrained only by the humans that it has to patiently wait for. And so forth.

Faster without a doubt, since before the Sinclair ZX80. Better; more so month by month, as noted above. It now even has better vision and mobility in restructed requirements. Before long it will be as good as what you see in the movies, such as "I Robot", or "Terminator".

People are so gullible that they don't have a clue or a chance! They think that "scientists" are a band of truthful & honest angels sent from God, while also hating them. Curiously, they also think the same of any shysters, such as Princess Greta or politicians such as Angela M. Sheeple...easy to control & slaughter at will. The above article from Physics Today is a case in point. The publishers don't question the concept of climate manipulation... as already done by HARP & aerosol spraying.

No wonder there's a popular perception of the 'mad scientist'. Yes, but nothing is done about controlling the mad scientist (of whom there are many), because the proletariat has NO power, it is impotent & mute. The real powers at the top may nod politely and allow a little voice for a little time, but will do what they want anyway. They are never held responsible. because they ARE the law.
