THAT IS NOT TRUE. Clearly the climate change deniers are not interested in what actually happened but in fact the globe was warming through that period. The article below explains what happened.
A global warming pause that didn’t happen hampered climate science
The supposed blip in warming fueled climate skeptics and distracted researchers

There’s no doubt that global temperatures are on the rise – a heat-up that is contributing to melting ice (icebergs in Ilulissat Icefjord in Greenland are shown), rising sea levels and extreme weather.

It was one of the biggest climate change questions of the early 2000s: Had the planet’s rising fever stalled, even as humans pumped more heat-trapping gases into Earth’s atmosphere?
By the turn of the century, the scientific understanding of climate change was on firm footing. Decades of research showed that carbon dioxide was accumulating in Earth’s atmosphere, thanks to human activities like burning fossil fuels and cutting down carbon-storing forests, and that global temperatures were rising as a result. Yet weather records seemed to show that global warming slowed between around 1998 and 2012. How could that be?

After careful study, scientists found the apparent pause to be a hiccup in the data. Earth had, in fact, continued to warm. This hiccup, though, prompted an outsize response from climate skeptics and scientists. It serves as a case study for how public perception shapes what science gets done, for better or worse.
A global warming pause that didn’t happen hampered climate science
Trying to explain why global warming appeared to slow down in the early 2000s distracted scientists and shook their confidence.www.sciencenews.org
Ian Plimer and his theories on why CO2 follows rather than leads global warming ? Sorry he is totally out on a limb there. If one wants to highlight the effects of various global warming tipping points then certainly the initial warming cause by extra CO2 will create additional warming.
For example warming up the Arctic tundra will release billions of tons of methane currently trapped in the perma frost. A warming planet that kills off large areas of forest will reduce CO2 retention and release more CO2 from decaying forests. But on all the evidence to date extra CO2 and other GG in the atmospehere will in itself increase temperatures.

Not sure why you were unable to access the story. I'll copy it full for your benefitYour link ultimately leads to a firewalled article so you didn't even read the original piece. Nice try.
Global Warming changed to Climate Change due to this period of hiatus. You know that.
It's quite a mystery how the temperature goes up and down and sideways, with and without CO2 influence. Maybe some natural variation is involved.
Very profound Wayne ..Nah, a trace gas at ⁴/10,000ths of the atmosphere is the real problem
Very profound too, Grasshopper.Very profound Wayne ..
But did you realise CO2 levels are 4.16/10,000th of the atmosphere ? I'm sure wherever you got that figure wouldn't have bothered to be so specific. And anyway 4/10,000 is the rough figure
Yeah it is small. And what is even more interesting is that if this 4.16/10,000th were to be, say 2/10,000th, the planet would be in an Ice Age. Mile high glaciers in New York. Europe under ice. The full caboodle.
That is the effect of this "measly" greenhouse gas. Too little and insufficient heat is trapped to keep the world from rapidly freezing. Roughly the right amount and we see the broad climate parameters of the past 10,000 years.
But the increase in CO2 levels by the amount we have done in the past 100 years is trapping far more heat than ever before. That is why global temperatures have increased to record levels (for the last 10k years) so sharply in just 50 years. And the full effects of the current CO2 levels have yet to be felt.
Check out this link for an in depth scientific explanation on how CO2 effects temperatures on Earth. I have quoted a small section.
Why does carbon dioxide let heat in, but not out?
Energy enters our atmosphere as visible light, whereas it tries to leave as infrared energy. In other words, “energy coming into our planet from the Sun arrives as one currency, and it leaves in another,” said Smerdon.
CO2 molecules don’t really interact with sunlight’s wavelengths. Only after the Earth absorbs sunlight and reemits the energy as infrared waves can the CO2 and other greenhouse gases absorb the energy.
How can CO2 trap so much heat if it only makes up 0.04% of the atmosphere? Aren’t the molecules spaced too far apart?
Before humans began burning fossil fuels, naturally occurring greenhouse gases helped to make Earth’s climate habitable. Without them, the planet’s average temperature would be below freezing. So we know that even very low, natural levels of carbon dioxide and other greenhouse gases can make a huge difference in Earth’s climate.
Today, CO2 levels are higher than they have been in at least 3 million years. And although they still account for only 0.04% of the atmosphere, that still adds up to billions upon billions of tons of heat-trapping gas. For example, in 2019 alone, humans dumped 36.44 billion tonnes of CO2 into the atmosphere, where it will linger for hundreds of years. So there are plenty of CO2 molecules to provide a heat-trapping blanket across the entire atmosphere.
In addition, “trace amounts of a substance can have a large impact on a system,” explains Smerdon. Borrowing an analogy from Penn State meteorology professor David Titley, Smerdon said that “If someone my size drinks two beers, my blood alcohol content will be about 0.04 percent. That is right when the human body starts to feel the effects of alcohol.” Commercial drivers with a blood alcohol content of 0.04% can be convicted for driving under the influence.
“Similarly, it doesn’t take that much cyanide to poison a person,” adds Smerdon. “It has to do with how that specific substance interacts with the larger system and what it does to influence that system.”
In the case of greenhouse gases, the planet’s temperature is a balance between how much energy comes in versus how much energy goes out. Ultimately, any increase in the amount of heat-trapping means that the Earth’s surface gets hotter. (For a more advanced discussion of the thermodynamics involved, check out this NASA page.)
How Exactly Does Carbon Dioxide Cause Global Warming?
CO2 molecules make up only a small percentage of the atmosphere, but their impact on our climate is huge. The reason comes down to physics and chemistry.news.climate.columbia.edu
CAGW alarmists have been trying to debunk this graph below for some time and their argument is that correlation does not equal causation, because of a multitude of other factors affecting global climate. Like....the sun....etc, etc.
It only takes a second or two to consider this with contemporary arguments that CO2 going up = increased temperature to realise there might be something wrong with this argument.
And, even though we have very clear historical scientific examples of CO2 and temp not being correlated, like the CET in the early 1700s and ice cores, the CAGW alarmists still don't want to use the scientific method to disprove their hypothesis.
There is no possible way of scientifically proving CO2 is the climate control knob.

What probes did they use in the 1700’s?
Did they compensate for the methodology?
Asking for a friend ?
These 'extinction rebellion' people must be short few IQ points. They like to cause traffic disruption to highlight environmental damage.
Today in Adelaide a member of the extinction group caused two major roads to be closed and diverted, causing travel time to increase by up to 2 hours. Local radio stations were flooded with calls from angry people trying to get home from night shift and others trying to get to work or drop off family.
How much damage did these extinction crowd cause today? Thousands of cars idling for up to 2 hours tons of emissions dumped into the atmosphere and fuel wasted. Thousands of people inconvenienced, late for work or a critical appointment, maybe missed saying goodbye to a loved one.
It appears that they like to use the labour of retired people, because the police and courts go easy on them.
From what I hear, extinction rebellion lost a lot of support today.
Extinction rebellion protester Meme Thorne is arrested after disrupting Adelaide traffic by abseiling from the Morphett Street Bridge
Ms Thorne, 69, of Willunga, said she engaged in the dangerous stunt to draw attention to issues surrounding fossil fuels.

Energy minister Tom Koutsantonis, who spoke at the conference this morning, slammed the actions of protesters.
“They’ve chosen to protest on a feeder road that leads to the Royal Adelaide Hospital, there are people probably going into day surgery, change of shift, let alone the way ambulances are getting in and out and the inconvenience they are putting on the people of South Australia is by far the most insulting thing they’ve done,” he told ABC radio.
Mr Koutsantonis said the protesters were welcome to protest outside the conference and had to right to do so, but their methods were “reckless”.
“They should know better. If you care about your fellow man and your fellow woman, then you care about our state.
“You don’t block roads leading to hospitals. You don’t keep ICU workers in a car when they haven’t slept for 24 hours. You don’t inconvenience them from going to work or going to school, it’s silly.
“Hanging off the Morphett St bridge doesn’t do a thing to decarbonise the state, nothing.”
Multiple ICU workers told how their travel times were impacted due to the protest.
Dean, who had finished a night shift in ICU at the North Adelaide Hospital, said he had been awake for 24 hours.
Extinction Rebellion spokeswoman, Kate Mettam, 67, defended the extreme protest stunt.
“Meme’s life is hanging by a thread, by a lifeline, and we say that the future of the planet is hanging by a thread.”
“Our state government declared a climate emergency last year and (now) they’re holding a coal and oil gas conference.”
Ms Mettam said the traffic delay was a “minor inconvenience,” compared to the irreparable damage of climate change.
“What is coming and what is already happening is major disruption,” she said.
“Disruption is fleeing from a bushfire, disruption is what’s happening in the Congo with people dying in floods. Disruption is what is happening in Siberia. Elderly people cannot leave their house in time and they’ve been burned to death in their house.”
The group of protesters were heard chanting: “No more gas, no more oil, keep the carbon in the soil.”
Photo and name of the peanut has been released. This is her third offence.
First one was May last year, she glued their hands to Flinders Street in front of Santos House, but reiceved neither a conviction or penalty.
Three months later she climbed the roof of Rundle Mall Plaza and glued her hands to the veranda, received a 6 month good behaviour bond.
Yesterday she was charged with obstructing a public place and disturbing the peace, released on $500 bail. Police Prosecutor objected to the leniency of the bail and quick release.
Three Extinction Rebellion protesters have pleaded guilty to damaging the Santos building with paint – and to spraying two police officers as well.
In the Adelaide Magistrates Court on Friday, Sarah Edwards and Bradley Homewood pleaded guilty to a number of counts arising from the protest on Thursday.
Homewood, 50, of Williamstown in Victoria admitted using a fire extinguisher filled with paint and water to spray the building.
Edwards, 49, of East Lismore in NSW, pleaded guilty to the same charge.
She also admitted “recklessly” spraying two SA Police officers with her “diluted” paint-filled extinguisher, causing $5346.28 damage to their leather and Kevlar armour.
Meanwhile, one of the protesters released on bail on Thursday returned to court seeking to alter her release conditions – then opted to plead guilty instead.
Edwards, Homewood and Heinke Weber said they would split the $5345 damage they caused to the building three ways, meaning each will pay Santos $1781 compensation.

On Friday, a police prosecutor said both Edwards and Homewood had long histories of protest action interstate, and multiple convictions for disorderly behaviour.
He said Edwards was currently serving a good behaviour bond for like offending in NSW, involving a protest that disrupted traffic on the Sydney Harbour Bridge.
“She has come into SA with the clear and sole intention of protesting in a manner that causes large-scale damage,” he said.
“Given this offending and her interstate history, we say it may certainly be that imprisonment is now appropriate.”
Homewood, he said, had shown a “clear intention to continue to offend” despite “having received leniency” in the past.
“The community needs assurance the courts will hold people accountable for this type of offending,” he said.
“If little or no penalty is given, it does nothing to stop this occurring.
“It’s not the aim of SA Police to stop anyone from exercising their lawful right to protest, but his was criminal behaviour, not a peaceful protest.”
James Caldicott, for all three protesters, said Edwards was a community-minded registered nurse whose offending could not be compared to “ordinary” cases of property damage.
He asked she be sentenced to compensation and time served, and not banned from participating in future Extinction Rebellion events.
“This was not a criminal enterprise, this was not delinquency, but an act intended to bring light to an important issue,” he said.
“They’re trying to bring attention to a noble cause but have stepped one step too far.
“That does not excuse the conduct and does not mitigate it in that sense, and none of what’s been said here excuses the behaviour.”
Magistrate Michael Barnett replied: “Why mention it, then?”
I'll accept that's probably true, but it's only due to the ignorance of the majority.From what I hear, extinction rebellion lost a lot of support today.
I'll accept that's probably true, but it's only due to the ignorance of the majority.
This lot and certain others haven't been serious about this issue for years now. It's a big game and nothing else - protest and demand that x be done, then protest again because x is being done.
Everyone does realise that it's less than a decade ago that environmentalists were campaigning for gas, right? Nuclear, hydro and indeed electricity in general = bad. Gas = better. That was the message until not long ago. A load of nonsense, but it was the message nonetheless.
I say that as someone who's firmly in favour of moving to actually sustainable energy systems as a priority. I'm just not in favour of doing it by means of obstructing the work of hospitals and their medical staff or of making a career out of protest. What we actually need, if it's to be done, is really quite simple:
Electrify everything that can be electrified.
All out construction of wind, solar, hydro and, not overly relevant to Australia but it certainly is in some places, nuclear and geothermal.
Plus supporting infrastructure, that is electricity networks, to support the above.
Some debunking of the nonsense and myths surrounding it all wouldn't go a miss either. Among others - no transmission lines won't make cows and crops radioactive, yes heat pumps are proven technology indeed it's how your fridge works, yes Australia has quite a number of viable hydro sites, no batteries aren't suitable for deep storage at present and so on. Teaching high school science students some proper physics wouldn't go a miss either, indeed gravitational potential energy and nuclear fission are both perfectly legitimate topics of real world relevance.
This nonsense of demonising the solutions, advocating gas, then protesting about gas is just a game for the sake of it. Having a laugh and nothing more.
For anyone who doubts that environmentalists promoted gas, I'll simply say this. Find anything on the subject from the 1970's, 80's, 90's, 2000's or even well into the 2010's and you'll find it's there. Anything from how Europe should generate electricity to how someone in Melbourne should heat water you'll find that was the standard advice - go for gas and the big name organisations put their name to it at the time. Such a pity they took society down a dead end path - we need electrification not a dash for gas.
Although it's a bit off topic, the gas advocates of the day proposed that as the least worst solution when we principally had only FF as energy sources.I'll accept that's probably true, but it's only due to the ignorance of the majority.
