Again? It was never green in its current location at the South Pole. It wasn't always there.
That's actually not correct. Antarctica was green at the South Pole.
Quote:https://www.sciencefocus.com/planet-eart...outh-pole/
Around 450 million years ago parts of Antarctica were actually north of the equator, and the continent only arrived at its present position at the South Pole within the last 70 million years or so. Even then, the much warmer global climate kept it free of ice.
Antarctica's present ice sheet dates from around 35 million years ago.
Thanks for the correction.

Well, 10 climate scientists and 490 filler signatories, many of whom weren't scientists of any sort.
Quote:From: Professor Guus Berkhoutguus.
berkhout@clintel.org
So you think that the IPCC is too politicized to be trusted but you'll willingly swallow the bollox being produced by researchers and organizations accepting dark funding from fossil fuel companies. Does the hypocrisy burn?
Quote:Natural as well as anthropogenic factors cause warming
Strictly true, but disingenuous since it neglects to mention that the anthropogenic factors have become orders of magnitude larger than the natural ones.
Quote:Warming is far slower than predicted
Far slower than who predicted?
Quote:Climate policy relies on inadequate models
According to...??? Climate modelling is admittedly difficult, but should we really wait to develop a 101% accurate model before taking action? I'm told that lifeboat policy relies on inadequate models of the Titanic's rate of sinking. It's only going down half as fast as we thought. Clearly we can ignore it since lifeboats cost money.
Quote:CO2 is plant food, the basis of all life on Earth
This is the sort of imbecilic tripe that proves that the speaker doesn't have the first clue. Sugar is human food but we don't grow so well on a 100% sugar diet. You'd think that Aractus might understand this nutritional lie.
Quote:Global warming has not increased natural disasters
A quick search on Google Scholar shows that this statement is a load of horseshit.
Quote:Climate policy must respect scientific and economic realities
Isn't it a shame that the author couldn't manage that.

Sadly, no. It is all axial tilt. The Earth doesn't rotate around a straight up and down axis. It is tilted about 23.5 degrees (probably from a planetesmil hit that also formed the moon). So the Earth heats unevenly. In the north, it gets more direct sunlight in Summer, less in Winter. Reverse for the South.
The regular orbital changes do make some differences. But if you want to go into those weeds, it gets really complicated.

A greenhouse works by trapping heat: hot air is not allowed to escape. As i just have stated: He lacks knowledge of the very basics, yet thinks he can lecture professionals (or accuse them of dishonesty, based on his ignorance).
The comparison with a greehouse is, partially, valid, and for this validity the analogy was chosen by schientists. The did this in order to visualise the issue to the ignorant, like Aractus: Yet just with evolution (and lots of other things), the ignorant are too ignorant to understand even the simplification done for them, turn around with their false notion and think they know better. In other words: Nothing to see here, pass on, its all just Dunning-Kruger.
Why is the comparison (partially) valid? Because glass is transparent to light at optical wavelenths and completely opaque to mid infrared, just like earths atmosphere. Energy that is irradiated into the system across all wavelenths gets transformed into mainly mid infrared (typical wavelenght of radition at 270K = surface temperature of Earth) and then the mid infrared can not be radiated back through the opaque(!) glass. Thus energy gets trapped in the glass house.*
tl;dr: the comparison is not invalid because glasshouses prevent movement of (hot) air, but valid because of the ablility (of both glass houses and the atmoshpere) to absorb radiation across a big range of wavelenths and emit only across a narrow(er) wavelenght, thus trapping the remaining energy
Looks like scientists need to dumb down more, for people like Aractus, the comparison of properties of gases (in Earths atmosphere) with stuff Aractus knows. It certainly is not greenhouses.
*and of course, the hot air carrying the glass house cant escape the glass house. Even in this regard the comparison is valid: hot air can move locally, but certainly not escpae the atmospere, thus the energy is still trapped even if you look at the problem only through the glass of "convection", like Aractus does.
As an engineer i am shocked time after time what amateurs like Aractus think scientists (and academics in general who spend the better time of a decade or longer) were doing all those years during and after study. Drinking at frat parties? And then a dude like him comes along, reads up some shit on the interwebz and thinks he has some competence or credibility. There is a fucking reason a scientifc education costs a fortune in countries like the USA.

I've had such discussions as this several times in the last 15 years. Deniers will always cherry pick and fall into the sharp shooter fallacy to feel like they know more than scientists. They will use conspiracy theories about grant money, when, if scientists were all about the money, they'd be a shill for the oil companies. They will shrug and say climate change has nothing to do with unprecedented levels of CO2, when stratospheric cooling data validates the predictions of greenhouse warming. They will cite the opinion of some meteorologist or physicist who has never done a climate study, has no data to back up claims, and is actually a red tie republican. If they were capable of critical thinking, they would learn the science for themselves and turn skeptical toward denial. After all, if you're not skeptical of your own skepticism, you are no skeptic.
In short, climate change deniers carry the same bag of shit as religious apologists.
Great first post ... welcome, and post more.

Plants do absorb CO2. But they they don't live forever. And they give up what they collected when they die. But what is more concerning is the melting of the permafrost. Millennia of plants are now exposed to heat and are giving up the CO2 they held. Things are even worse than "the crazies" said decades go.
We're in a deep serious plantload of carbon trouble...

Considering what Aractus wrote about coal being a "natural" source of CO2, he doesn't even understand the concepts of carbon sinks and sequestration.

I wasn't sure which angle they were going for with that absurdity. On the one hand they'll argue that plants take up CO2, so more CO2 makes them grow faster and that's good for agriculture, forestry, etc. Which completely ignores the fact that CO2 is rarely the limiting nutrient for most plants, that increasing one nutrient does not make for a healthier organism, and that the changes to climate are going to be more of a detriment than a simple boost in CO2 availability will ever offset.
On the other hand they sometimes argue that plants absorb CO2, suggesting that forests are some sort of CO2 sink. Which would apply if you were growing more forest than you were cutting down. As you mentioned, a forest in equilibrium has a net zero carbon footprint, releasing carbon back to the environment at the same rate that it absorbs it. And it isn't as if we're increasing the net biomass of plant material. Burning down the Amazon is just the latest in the millennia-long deforestation effort by our species.
Thawing of the permafrost is very worrying but for real nightmares try out methane clathrate destabilization.

Here is a newer report about methane...
"In response to warming ocean waters, hydrates can degrade, releasing the methane gas. ... In addition to methane hydrates, carbon-rich permafrost that is tens of thousands of years old—and found throughout the Arctic on land and in seafloor sediments—can produce methane once this material thaws in response to warming.Jan 17, 2018".

I won't be around to lack oxygen in we continue to ignore the problem. But the children of my nieces ad nephews will. I wonder what it is like to gasp for oxygen? Not that I want to know. But it will happen if we don't do something.
And let me add here that many (too many) theists think that it is "impossible for humans to change what God controls" so we don't have to worry about it.
Let me just add that levels of oxygen haven risen an dropped naturally. But we are doing it this time. And consider this... The human brain consumes 20% of all the oxygen we take in. Brains are oxygen-burners. Other animals need less than we do. We'll be the first to go, when the level drops.
And if that isn't bad enough, our possible successors are the other high-brain oxygen-burners. Think about that...

I like to think I have sense of humour. A part I sometimes forget; MY rule 42: always take the opportunity to NOT take myself too seriously.
Not especially fussed with Greta Thunberg. Am however impressed with what she has accomplished personally because Asperger's can be very socially limiting.
Her message is very much a matter of preaching to the choir with me.
However, I AM thrilled at the response to her world wide from the youth. It has increased my faith in the next generation. As long as they don't come over all middle class and complacent in their late twenties as my generation did.
These days I decline to become involved in arguments about the validity and extent of man caused climate change. Regardless of the idiotic behaviour of our Prime Minister and his party--- it's become mainstream science, period.
What have I done? well, not a lot as far as I can see, although I've done about as much as I can;
I DO recycle, using the 3 bins council has provided. However, Im unconvinced that more than a small fraction of my recycled waste is actually recycled.
In my home;
I have a 5kw solar power system. On a hot clear day such a today, the system typically produces over 20 kwh, sometimes as much as 30 kwh. The net effect of this over the three years I've had it is has been 30% drop in my energy costs.
Last year I got rid of my 2.4 litre Camry and bought a 1.5 litre Mazda 2. Much less use of fuel.
Garden; the first week after I moved in, I ripped out all the lawn, replacing out the front with 2 dozen rose bushes because roses are drought tolerant. Trees are mainly native as are shrubs. This coming year native succulents out the back as ground cover.
South Australia is the driest state in the driest continent.Our average rainfall is about 21 inches. It is my unpopular opinion that it's time South Australia got over its preoccupation with the English garden and lawn. True, some places use recycled sewerage water. This is great, as long as there is nothing more useful which can be done with such water, which here is potable.
Have outside blinds at the front of the house, plus reflective film on one window . Reflective film on kitchen window. This coming year new inside blinds. Also want to check the prices of retro fitting a type of double glazing. It just clips into existing windows. Also reduces noise.
I'm well aware that my efforts are very much a case of lighting a candle rather than cursing the dark . I will do more as money allows .
I had hoped I would die before climate change became personally inconvenient. I'm starting to think that may not be the case. Some times I feel like chewing carpet at the selfish stupidity of people who actually could make a vast difference. --and at our criminally ignorant, incompetent politicians and their apparent corruption.
