NOAA: Earth Smashed A Record For Heat In May 2014, Effects To Worsen
Freshly Exhumed (105597) writes with news that NOAA's latest global climate analysis is showing things are getting hotter. From the article: Driven by exceptionally warm ocean waters, Earth smashed a record for heat in May and is likely to keep on breaking high temperature marks, experts say. The National Oceanic and Atmospheric Administration Monday said May's average temperature on Earth of 15.54 C beat the old record set four years ago. In April, the globe tied the 2010 record for that month. Records go back to 1880. Experts say there's a good chance global heat records will keep falling, especially next year because an El Nino weather event is brewing on top of man-made global warming. An El Nino is a warming of the eastern tropical Pacific Ocean that alters climate worldwide and usually spikes global temperatures.
No, no it didn't happen. La La La La La - I can't hear you

It's weird how those old thermometers were always inaccurate in the negative direction.
Of course looking at that we would find that the Earth is in a fairly moderate area between much cooler global temps and much higher global temps.
The earth has been in the not so distant past very uncomfortable for humans in both directions. The earth some day will get much more tropical again. The earth will again see Ice Ages. These are true statements. Nothing we can do in the next 50 years will give us the technological expertise needed to do much of anything about warming or cooling.
Why is it so hard to only have politicians for a few years, then have them go away?
Yes, but the earths population wasn't as large 'way back when'.
The coastline ending up a few more miles inland didn't matter as much when there was room for the population to move back from the edge.
Now ?, well, a large proportion of the worlds most densly populated areas may well become uninhabitable, and really, no where for large numbers of people to go.
The only 'easy' fix is less people, and I imagine one way or another, that will be the outcome.
If only we knew which thermometers are located in the heat islands so that we could filter them out...oh, wait!

You know, there's this funny theorem that in the absence of systematic errors, averaging measurements from multiple instruments (each of them systematically, but randomly-per-instrument overshooting or undershooting) and measurement times (each instrument having a random error here) keeps the mean centered on its true value while decreasing the measurement error.

Not really. Notice the word "warmists" there? It's used as a tribal identifier. In other words, symbolset's post is actually a boast against a perceived other tribe - no different than "your mom's fat". The actual content of the message is not about your mother's body composition, nor Earth's climate, but rather "this is our territory!". It's only an unfortunate accident of evolution that we use the same mechanism for establishing dominance than we use for problem-solving.
It's quite fascinating how much of human communication is utterly unrelated to its nominal content. And it also explains why these discussions tend to degenerate into poo-flinging contest in short order.
Forget magic. Any technology distinguishable from divine power is insufficiently advanced.
Do you have a citation saying that the MWP was warmer world wide?
As for the the earth being colder during the Devonian period when CO2 was higher, the Sun was significantly dimmer back then.
"The hysteria and FUD and the billions of dollars and euros wasted on "climate modeling" is absurd"
Understanding reality is not hysteria, trying to deny it is.
They never changed the name. Please stop being so freaking stupid.
Global warming = Energy captured by excess CO2
Climate change = how global warming impact the climate.
Climate disruption= Economic change do to climate change.
Te first two came int' use almost at the same time.
They are all related but different things. No one is changing anything. I understand the the media confuses the terms, and some pundits use that as some sort of ad hom attack, but you need to be better then that.

The question is not only if the climate is changing, but if it's directly related to CO2. Robert Essenhigh's point is quite interesting. http://bit.ly/11IsUri
It was quite interesting until he failed to explain how heat produces CO2, after claiming that it was easily explainable; when he claimed that a ~5% increase in CO2 release from burning fossil fuel for energy was "statistical noise" and implied that it was the extent of industrial production of CO2, he became a denialist liar. There are numerous other industrial sources of CO2; for example, the production and curing of concrete alone (not accounting for the CO2 release of burning the energy, already accounted for here) accounts for approximately 2.5% of our CO2 emissions. Iron and steel production are likewise carbon-intensive processes, even putting aside the energy consumption. He also doesn't back up his statement that only two possible causes deserve explanation, nor what the four possible causes are, etc etc. He also blames the entire thermal forcing on water vapor, but relative humidity (the only kind of humidity he mentions in the linked page) is decreasing due to rising temperatures.
tl;dr: Essenhigh is trivializing human CO2 production, which exceeds volcanism, and also failing to back up his statements.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
why are so many people her suckered by pundits?
Pay attention:
1) Visible light hits the earth. Falsifiable, and tested.
2) When visible light strikes something, IR is generated. Falsifiable, and tested.
3) CO2 is transparent to visible light. Falsifiable, and tested.
4) CO2 absorbed energy from IR. Falsifiable, and tested.
5) CO2 in the atmosphere is increasing. Falsifiable, and tested.
6) The VAST majority of excess CO2 in the air is generated by humans. Falsifiable, and tested.
That's it. That is global warming. If you disagree with that, then you need to prove where the science is wrong. I look forward to your noble prize winning paper.
If you read that and still think it doesn't impact the climate(climate change) then you need to show where the absorbed energy is going.
Some of you are very disappointing, falling into ad hom attacks and bad science. Scien that can trivally be checked out. But no, some of ypu moron keeps spouting the same crap.
AGW is a scientific fact.
The Kruger Dunning explains most post on
Why is it that the global warming deniers can't decide whether warming isn't happening, it is happening but it isn't human-caused, or it is happening, it is human-caused, but it isn't economical to do anything about it? It can't be all 3, yet the deniers can't seem to get their story straight.
The truth is that it's the 3rd option. Deniers first argue that it isn't happening. When science proves them wrong, they then argue that it is happening but isn't human caused. When science proves them wrong again, they fall back to their real position that despite it existing and being human caused, it isn't worth doing anything about because that would take work and cost money. It's very dishonest.
Water vapor isn't a spoiler - the bands that it absorbs are different from the bands that CO2 absorbs. That's all there is to it really. There's so much water in the atmosphere that water vapor bands are essentially entirely absorbed. We can't reduce the amount of water in the atmosphere, and we wouldn't want to even if we could, so any gains that we make have to be outside the water absorption spectrum.
Such equipment records surely don't exist back to 1880.... So, my argument stands.
Just because you think something couldn't possibly be true doesn't mean it isn't.
Thermometer manufacture was precise enough to produce very high quality instruments by the late 1800s. The issue, as GP points out, isn't random errors popping up (thermometers were about as accurate as rulers could be in the late 1800s), but rather whether we know how the instruments were calibrated and how older scales might match up to instruments that were calibrated against modern international standards.
And, at least in the U.S., standard regular calibration standards had been agreed upon by the first couple decades of the 1900s. Good instruments even decades before then should have very little random error -- the question is only whether anyone bothered to check new equipment calibrated to international standards against the old equipment (or sent the old equipment to be tested once such standards were developed).
So, then you have to ask yourself: people who are bothering to meticulously record scientific data continuously for decades on end -- and they're not going to even bother to check whether their old instruments line up properly with new calibration standards?
Sure, I'm positive there are plenty of places that don't have such records. But we have continuous logbooks going back for centuries in many places. The idea that people taking meticulous records wouldn't even bother to check new equipment against old just seems a little ridiculous... not saying it wouldn't happen, but we have plenty of data points where it did happen to extrapolate estimates for error distributions.
You're acting like temperature measurement in the late 1800s was people guessing random numbers or drawing them out of a hat. But that's not what it was like, and there were lots of places with VERY detailed records.
You must have failed your stats 101 course in college. Let me educate you: any random sampling has limited accuracy. A randomly sampling of real temperatures that is made using low quality thermometers will probably have a very limited accuracy. But as you take more samples, you will either find that the measurements are biased or that they are normally distributed. If they are biased, you should be able to model the bias and apply a correction to achieve a normal distribution. Once you have a normal distribution, you know that an increase in the number of samples allows to say with a greater degree of confidence that the real value is within a certain range of the mean of those samples. So, even if you have shitty thermometers, you may be able to draw useful conclusions from them if you have thousands of measurements. This is the kind of stuff that the big boys talk about when they prepare journal articles for peer review. You know, p 0.05 and all that.
When El Nino leads to a new record high temperature by a large margin (for argument's sake, in 2015), the denialists will quietly adopt this as their new standard for 'normal' and in 2025 they'll be saying "warming is a hoax because temperatures haven't risen on average since 2015."

Thanks for pointing that out. Its a good thing Christopher Booker (author of your "story") is here to report on NOAA data fabrication.
/. favorite...get ready, its a doozy... Evolution is based on BS assumptions and BLIND FAITH and Intelligent Design is the truth!. If you include that last bit when you quote him it will be much easier to keep the stories straight. Your welcome!

Speaking truth to power
Holy smokes are you president of the Christopher Booker fan club?? From his wikipedia page "...he speaks truth to power...". From the 2 minutes of research I've done on him I'd say he speaks truthiness to power. He makes his living as a professional contrarian. All of his pubilished views are the opposite of scientific consensus in a vast variety of subjects. Its possible he could be smarter than all climate scientists, cancer scientists, infectious disease scientists, and Evolutionary Biologists. But there is a much higher likelyhood that he is just full of shit.
Yes, long before him. Gilbert Plass published a paper in 1956 titled:
Plass, G.N., 1956, The Carbon Dioxide Theory of Climatic Change, Tellus VIII, 2. (1956), p. 140-154.
I don't know about the rest of the world, but I'm pretty sure our local stations keep records of major instrument overhauls which can be taken into consideration.
I used to work in climate science and we had a saying: "If you give a thermometer to a meteorologist, he knows what temperature it is. If you give him two, he's confused."

A cursory googling doesn't paint Steve S. Goddard as someone that has a rigourous approach to statistical analysis.

There are multiple carbon cycles around us. One is the obvious, atmospheric one, where rotting plants and animals release CO2 and growing plants sequester it again, on a timescale of dozens of years. Another is a long term one, in which carbon contained in marine sediments gets transported deeper in the tectonic subduction zones, the hydrated carbon-containing rocks then get into areas of high temperature where their hydration decreases the melting point of those rocks and the surrounding environment to the extent that the rocks melt, form magma, and volcanism and CO2 outgassing ensues. That happens on a timescale of millions, or tens of millions of years.
There seems to be a number of feedback loops in this latter process that increase the absorption of CO2 if there is too much of it in the atmosphere and decrease its absorption if there is too little of it, while the volcanoes dump the CO2 back at some random but I guess roughly stable rate (dictated by how fast the tectonic plates deliver the carbon to be outgassed, and this process doesn't care much about what happens on the surface).
And here's the problem: The carbon we're digging up and burning right now had been slowly deposited from the atmosphere into coal and oil over a long period before we started mining it, while these feedback mechanisms had enough time to continuously keep the atmospheric CO2 at some level using these deep crust reservoirs. But now we've been burning the coal and oil quickly, so even though the total amount of carbon in the air, water, continental rocks, marine rocks and generally, the Earth's crust stays the same, and while these feedback loops are stil in effect, we're pumping it from continental rocks (coal, really) into the atmosphere way faster than these long-term cycles can re-deposit it back into the deeper crust.
(But I'm Not A Geologist, so if there is one around and I got it wrong, please correct me on anything.)
