Once upon a time there was a robot, named R1 by its creators. Its only task was to fend for itself. One day its designers arranged for it to learn that its spare battery, its precious energy supply, was locked in a room with a time bomb set to go off soon. R1 located the room, and the key to the door, and formulated a plan to rescue its battery. There was a wagon in the room, and the battery was on the wagon, and R1 hypothesized that a certain action which it called PULLOUT (WAGON, ROOM) would result in the battery being removed from the room. Straightway it acted, and did succeed in getting the battery out of the room, but didn't realize that pulling the wagon would bring the bomb out along with the battery. Poor R1 had missed that obvious implications of its planned act.
Back to the drawing board. "The solution is obvious," said the designers. "Our next robot must be made to recognize not just the intended implications of its acts, but also the implications about their side effects, by deducing these implications from the descriptions it uses in formulating its plans." They called their next model, the robot-deducer, R1D1. They placed R1D1 in much the same predicament that R1 had succumbed to and as it too hit upon the idea of PULLOUT (WAGON, ROOM) it began, as designed, to consider the implications of such a course of action. It had just finished deducting that pulling the wagon out of the room would not change the color of the room's walls, and was embarking on a proof of the further implication that pulling the wagon out would cause its wheels to turn more revolutions than there were wheels on the wagon---when the bomb exploded.

Re: Global Climate Change Science News
AI is faster and better at Jeopardy, at diagnosing cancer, at chess, at go. This potential for excellence in specific endeavors has been known about AI since the beginning. The bigger problem for AI researchers has proven to be developing what might be called a general intelligence, something capable of leaving the Jeopardy game to navigate the larger world. I think Dennett talks about this in his essay "The Frame Problem of AI". Here's just a bit from that:

Re: Global Climate Change Science News
The reason why Galaxian is usually right is because I don't pay much attention to Greta Thunberg or IPCC or NASA proclamations. You really have to steer clear of zealots & crooks... they have an agenda to fulfill, either for reward or threats.Brian Peacock wrote: ↑Thu Jan 02, 2020 10:44 am"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."
https://physicstoday.scitation.org/doi/ ... /PT.3.4389
So back to brass tacks: There's no such thing as an upper "safe level" of CO2. Because this trace gas does most of its heat retention work at low concentrations. Doubling its concentration does NOT double its effect... it is a law of diminishing returns. That's why the CO2 concentration has been several times higher in the past without ill effect to the forests or the oceans or their inhabitants:
https://wattsupwiththat.com/2010/03/08/ ... n-dioxide/
https://i2.wp.com/wattsupwiththat.com/w ... =605&ssl=1
Notice how the influence curve levels out at 550 ppm, such that the insulation effect rises by just 10 W/m2 from 400 to 600 ppm, that's just 4% !
https://i2.wp.com/wattsupwiththat.com/w ... =598&ssl=1
Here's something even more pertinent: It relegates CO2 to its lowly place as a minor constituent of the bogus anthropogenic global warming. Remember that water vapor has a much higher influence... Do they intend to get rid of clouds, humidity, & rain?
It's important that we don't become 'virtue-signalling' bigots...That's the ones totalitarians & despots relish most of all

Merely proves IPCC claim. The significance ofvthe first 20 ppm does not change the conclusion of the models. The shading of the bar graphs is supposed to point out that the CO2 quit warming past 300pm. There are other sources that disprove that.
Paper has no sources for the data. But Archibald is a well known cherry picker.

Re: Global Climate Change Science News
Moreover, the climate models do NOT assume a linear effect:
Annual atmospheric carbon dioxide (NOAA) and annual global temperature anomaly (GISS) from 1977 to 1985 and 1981 to 1989.
What causes this climate variability? Ocean cycles shuffle heat around the climate by exchanging heat between the ocean and atmosphere. This can have a strong short term effect on global temperature, the most dominant cycle being the El Niño Southern Oscillation. In 2008, the Pacific Ocean was in a strong La Niña phase, leading to unusually cool temperatures throughout the tropical Pacific Ocean.
https://skepticalscience.com/
variability is know as well:The amount of CO2 is increasing all the time - we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase.
A tiny amount of CO2 and other greenhouse gases, like methane and water vapour, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be without them. We have added 42% more CO2 but that doesn't mean the temperature will go up by 42% too.
There are several reasons why. Doubling the amount of CO2 does not double the greenhouse effect. The way the climate reacts is also complex, and it is difficult to separate the effects of natural changes from man-made ones over short periods of time.
As the amount of man-made CO2 goes up, temperatures do not rise at the same rate. In fact, although estimates vary - climate sensitivity is a hot topic in climate science, if you’ll forgive the pun - the last IPCC report (AR4) described the likely range as between 2 and 4.5 degrees C, for double the amount of CO2 compared to pre-industrial levels.

Re: Global Climate Change Science News
Galaxian's general mistrust of authoritative voices is perhaps understandable, but aside from the irony of casting himself as the authority here, if that mistrust was justified in every case we wouldn't have bothered coming down from the trees.
He really doesn't understand how science operates or how scientific understandings are established and yet always remain provisional in nature. Science is a progressive endeavour, and yet because some science may be overturned or understood in a different context in the future -- as indeed it may -- then Galaxian implores us to assume not only that we are mistaken to think we are entitled to know what we know today, but that if we do we have been misled or deceived by maliciously malign agents.
The facts don't care about your trust issues mate. The maliciously malign agents here are those who explicitly exploit your insecurities in order to maintain their own authority and control. Have you not noticed that scientists don't actually run the world, but only seek to explain some aspect of it?

Re: Global Climate Change Science News
The big end of town is moving away from coal:
https://www.abc.net.au/news/2020-01-28/ ... s/11903928
https://www.abc.net.au/news/2020-01-28/ ... s/11903928
It was a story that raised a few hackles, particularly in Canberra, but one largely overlooked as the unfolding disaster gripped the nation.
Early last month, as fire swept across large parts of the east coast and South Australia but before the Christmas conflagration, secret internal documents detailing ANZ's rapid retreat from coal hit the news.
Contrary to its public statements before Parliament just a few weeks before, the bank had formulated a plan to shed more than $700 million in thermal coal loans within the next four years: a 75 per cent reduction.
This was a major shift for ANZ, the country's biggest lender to the coal industry, and one that would bring it into line with the Commonwealth Bank and the National Australia Bank.
A few weeks later, investment bank Goldman Sachs, in one of the strongest positions from any American financier, ruled out future thermal coal financing, either for new mines or power stations globally.
Then, a fortnight ago, the world's biggest investment house Blackrock, announced it was drastically reducing its exposure to thermal coal.
These weren't knee-jerk reactions to the horror, the wholesale destruction and tragic loss of life across rural Australia, unfolding on television screens around the world.
Nor were they the actions of the "green left".
These were considered, long-term, strategic decisions made individually by disparate groups united by a single cause — the unbridled pursuit of profit.
The message each is broadcasting is clear. When it comes to investment, coal, particularly thermal coal for electricity generation, has little, if any, future.
It's a message our politicians should heed if they want to limit the damage to communities that rely upon the coal industry.
