Global Warming Started 180 Years Ago Near Beginning of Industrial Revolution, Says Study (smh.com.au)
New research led by scientists at the Australian National University's Research School of Earth suggests that humans first started to significantly change the climate in the 1830s, near the beginning of the Industrial Revolution. The findings have been published in the journal Nature, and "were based on natural records of climate variation in the world's oceans and continents, including those found in corals, ice cores, tree rings and the changing chemistry of stalagmites in caves." Sydney Morning Herald reports: "Nerilie Abram, another of the lead authors and an associate professor at the Australian National University's Research School of Earth Sciences, said greenhouse gas levels rose from about 280 parts per million in the 1830s to about 295 ppm by the end of that century. They now exceed 400 ppm. Understanding how humans were already altering the composition of the atmosphere through the 19th century means the warming is closer to the 1.5 to 2 degrees target agreed at last year's Paris climate summit than most people realize." "It was one of those moments where science really surprised us," says Abram. "But the results were clear. The climate warming we are witnessing today started about 180 years ago."
The deniers do not care, they will be dead before the worst hits. As long as they can live high on the hog on their imaginary money until they die, they are happy. There is not one drop of concern for the future of humanity or life on earth in general.
Tim Flannery keeps being quoted by the ABC and Fairfax as a global warming guru. So it’s important that we keep confronting the Climate Council head with his spectacularly dud predictions.
In 2005:
I’m afraid that the science around climate change is firming up fairly quickly . . . we’ve seen just drought, drought, drought, and particularly regions like Sydney and the Warragamba catchment—if you look at the Warragamba catchment figures, since 98 the water has been in virtual freefall, and they’ve got about two years of supply left . . .
Maxine McKew: But. . . we won’t see a return to more normal patterns?
Flannery: . . . they do seem to be of a permanent nature. I don’t think it’s just a cycle. I’d love to be wrong, but I think the science is pointing in the other direction.
McKew: So does that mean, really, we’re faced with—if that’s right—back-to-back droughts and continuing thirsty cities?
Flannery: That’s right.
(UPDATE: HELP WANTED! THE VIDEO OF THE ABOVE INTERVIEW McKEW DID WITH FLANNERY NO LONGER APPEARS ON THE ABC SITE. DOES ANYONE HAVE A COPY OF IT FOR ME TO SHOW ON TV?)
In 2005:
Perth is facing the possibility of a catastrophic failure of the city’s water supply I’m personally more worried about Sydney than Perth. Where does Sydney go for more water? At least Perth has a buffer of underground water sources. Sydney doesn’t have any backup. And while Perth is forging ahead with a desalination plant, Sydney doesn’t have any major scheme in place to bolster water. It also has nowhere to put the vast infrastructure of a desalination plant.,,
There’s only two years’ water supply in Warragamba Dam If the computer models are right then drought conditions will become permanent in eastern Australia.
In 2007:
So even the rain that falls isn’t actually going to fill our dams and our river systems...
Since then, of course, there have been repeated floods with dams in Sydney, Brisbane and Canberra filled to overspilling.
UPDATE
Melbourne ABC presenter Jon Faine, a fervent warmist, has advertised he will later today discuss what the NSW rain says about changes to our climate. It is yet to be seen if he links global warming to this rain, but Melbourne readers might wish to ensure any scaremongering is challenged (1300 222 774). Here are some facts and admissions worth noting from the latest report of the Intergovernmental Panel on Climate Change.
Some key passages:
On thunderstorms:
In summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms because of historical data inhomogeneities and inadequacies in monitoring systems.
On heavy rain events:
In summary, there continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale.
On cyclones and storms:
Over periods of a century or more, evidence suggests slight decreases in the frequency of tropical cyclones making landfall in the North Atlantic and the South Pacific Several studies suggest an increase in intensity, but data sampling issues hamper these assessments Callaghan and Power (2011) find a statistically significant decrease in Eastern Australia land-falling tropical cyclones since the late 19th century although including 2010/2011 season data this trend becomes non-significant ...
On extreme weather events:
For instance, evidence is most compelling for increases in heavy precipitation in North
It's true that really - it doesn't matter. On a geologic timescale, everything we do is happening quickly.
Regardless of how many electric vehicles we put on the road, or how much fuel efficiency we push, every, single, last, drop of gasoline on this planet will be burned in the next ~1000 years. On a geologic timescale whether we burn it all in 50 years or in 1000 it really isn't going to matter.
So basically, we just cross our fingers and hope that by the time we dump all the available CO2 into the atomosphere that's it's not borked to the point that the planet won't recover.
Truly - the only solution we're going to have to global warming is to hope that eventually we just run out of fossil fuels and clean energy is all that's left.

...even before humans had any significant CO2 output.
Good to know. I'm sure someone out there will find some magical particle humans were emitting in the 1800s at a certain level that didn't scale with the massive growth in population of humanity.
"The authors of the paper note it’s particularly interesting that global warming keeps winning the bet despite ocean cycles, solar activity, and human aerosol pollution all acting in the cooling direction over the past 15 years. Human-caused global warming has become so strong that it’s consistently overcoming these natural short-term cooling factors... In other words, betting against global warming is an almost sure way to lose money at this point."

They should have said 20,000 years ago, because that's when it started warming: https://en.wikipedia.org/wiki/...
My belief is that there's an overwhelming consensus amongst scientists who are experts in this field that man-made climate change is real and worth taking action to mitigate.
Except here they have it ass backwards with cause and effect, and need to read "The Critique of Pure Reason" from Immanuel Kant.
The industrial revolution was caused by the start of global warming. Before that, humans were huddling under blankets, complaining about how cold it was. When temperatures rose, the folks said, "Hey, it's warm outside, let's go out and build a factory or something!"

anti-science nutters that cannot understand
My irony meter just exploded.
Yes some warming is occurring, but not enough to matter in any way worth even getting excited about - at least that's what the hard facts and careful research tell us.
Funny how the anti-science nutters are always so highly selective about their "hard facts and careful research", hand-waving away all the rest of the data that doesn't fit their own narrative as "manipulated". Let me guess, the whole of the IPCC Working Group II's collected data is all compromised and ignorable, every bit; none of those described impacts could possibly happen, amirite?
Heck it's probably
Ah, another hard fact, with more careful research behind it?
not even enough to counteract the next global cooling phase which is close at hand
It started 8000 years ago, temperatures have been dropping since then - up until we changed everything.
Now the soft facts and panicked revelations made by so called "scientists" who are backed by governments trying to bilk the people into more central control
Now the baseless allegations of conspiracy and paranoia, with the inevitable government agenda behind it. Did you notice all the Australian climate scientists recently protesting their government's agenda?
But of course I forgot, they just want to keep their jobs, and they have to keep manipulating their data and falsifying their results even when their government clearly doesn't want to hear it - low-paying research on global warming is all they can do, because the fossil fuel industry certainly doesn't have any money for them.
isn't it astounding that after literally decades of being utterly wrong about long term climate forecasts, people still listen to them?
Dammit, my brand new irony meter just exploded as well.
Why would anyone engrave "Elbereth"?
That is not a belief. That is fact.
I prefer the "u" in honour as it seems to be missing these days.
Easy. Real Scientists follow the Scientific Method. They are empiricists who look at ALL the data, and if the data doesn't match their hypothesis they adapt their hypothesis.
The pseudo-scientists are also easy to spot. They talk about "consensus" (which is not part of the Scientific Method) because they don't want to talk about the satellite observations. They talk about computer models, but refuse to discuss why the computer models don't match observed reality. They discard any and all observations that don't match their hypothesis. They call for the legal punishment of their opponents. They care more about global wealth redistribution than whether the empirical data matches their Statist Collectivist worldview. They seek to control the flow of money, and want to dictate how you can live your life:

Actually, did you not know the Minoan Warm Period, Roman Warm Period and Medieval Warm period were warmer than today? This is why Vikings farmed in Greenland and wine grapes could be grown as far north as York in England. Now the graves of the Vikings are under 'permafrost', but it wasn't frosty in their day, because it has been much hotter in the past ! You talk about 'nutters' yet seem to be defending a position for which you don't even understand even the basic counter evidence. Furthermore, I would hope you would look at the statement of the leaders of the CAGW movement:

Because it's easier on their mind.
Let's be honest here, if we wanted to do something about global warming, we'd have to change our way of life. And we'd have to change it big time. We (Europe and the US) use up more resources than the rest of the globe combined. Yes, including China. But they're trying to catch up. Should they ever reach us, it's game over anyway. That this isn't even sustainable in terms of resource usage, not to mention waste production, is, at least to me, obvious. If you disagree, do so, I don't give a shit.
So if you admit that global warming is a reality, you can do two things: Either feel guilty about continued overusing resources or reduce your consumption. Either is not really something people want to do. The first makes you feel bad (and we all know how troublesome this is to the fragile souls of our millennials) and the latter inconveniences you.
So it's easier to just wish it away and say it ain't happening.
Personally, I found a third way. I simply don't give a shit about it anymore. Yes, I'm convinced that global warming is real, the data I have available points to yes. But so be it. I won't live another 50 years, so I don't give a fuck.
If you want to save your planet, go ahead. Hell, I'll even move along. But don't expect me to waste any more of what's left of my time on trying to convince people that they have a duty to their kids. If you don't give a shit about your kids, how could you expect me to?
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
And yet that's precisely what the original poster was complaining about. Climate scientists have progressively refined their models over the last few decades as more data became available and as computational power increased to the level that they can run simulations on a desktop that would have needed a supercomputer in the '80s (and far more complex ones on modern supercomputers). When they refine their models and obsolete some of their old predictions (or those of other researchers - there's nothing an academic enjoys more than proving another one wrong) then you grumble about the wrong predictions. When the new models predict some of the same things as the old, then you complain that they're not adapting their hypothesis.

Did they place it next to the 401, or did they place the 401 next to the weather station?
There are a few weather stations in my home country (and during my studies I had to deal with them a lot), some of them having been in place for centuries, and many of them in rather unfortunate positions, mostly because when they were established it was a necessity to put them close to where people lived (so you could get there on foot), without considerations for projects that were decades or centuries in the future.
Moving those weather stations isn't a good idea either, though, because by taking readings where they are, you get a very good instrument for examining change over time. Moving the weather station would destroy that ability.
Of course such changes in the environment have to be taken into account. If you had a weather station in the middle of a sunny, grassy hill and a huge skyscraper is built in front of it so it's now permanently in the shadow of said building, it doesn't mean that the average temperature dropped by 5 or even 10 degrees Celsius.
Environmental impact on the weather stations have to be taken into account!
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
As always, TFA fails to look at the broader context. 200 years ago was the Little Ice Age", i.e., an unusually cold period in history. Much of the warming of the past 200 years is simply due to coming out of this cold period. Exactly how much, is difficult to say.
Enjoy life! This is not a dress rehearsal.
Without the 90 percent massive subsidies that fossil fuels get, in depreciation, cheap federal and state lands (mining regs), escaping penalties for pollution by bankruptcy, and literal cash infusions for fossil fuel industries, they would be bankrupt today.
Let's help them along and get rid of all fossil fuel vehicle and business tax exemptions, tax deductions, regulatory escapes, and all the other things that subsidize these inefficient fossil fuel dinosaurs.
Literally.

Our betters also try to tell me that the northern hemisphere has over twice as much land area as the southern hemisphere, but my gut tells me that's a government conspiracy and that land and weather are equally distributed around the globe. Our betters also try to suggest that they've found evidence for warming in North America and the US during the medieval warm period, but the reason I know they're full of shit is because we didn't have satellites then, and even if we did they would have just fudged the data anyway. I don't trust thermometers anyway, I go outside today and it feels cooler than yesterday, so I know that today is colder than average. That's how facts work.
I also saw this climate map once, they were trying to show how things are warmer on average. But, check this out - one little part of the map was actually colder than average. That's how I know that they make everything up, because I understand that the entire planet always warms and cools at the same rate, and that local variation doesn't exist. That's how they try to convince you to send them all of your oil money, but the guy they hired to photoshop that map fucked up and left part of it cold and completely blew their cover.
And remember a couple decades ago when you couldn't even turn on the TV without seeing Sally Struthers whining about some starving African kid? You want to know why you don't see those any more? Because there aren't any starving people in the world anymore. I know this is a fact because I can drive down the street and there's a grocery store. That's how facts work.
