What happened to Global Warming?
When I put my first above ground pool in around the late 90's we were able to open it in April and start swimming in May.
Now my pool is just opened and still not warm enough to swim in
I'd like some global warming back...
Well I've read this argument of yours and you know what - you read too much into details.
Long-term predictions are NOT INTENDED to predict a 0.1 degree rise/fall over the course of a few years. It's intended to predict larger rises averaged over centuries.
As long as you're pre-occupied with details, you will never, EVER see the complete picture and arguing with you over the validity of a few datapoints out of thousands of points, or making weird conclusions about a measurements on the level of detail that falls well within the noise range, is completely POINTLESS.
And this too... just wtf are you babbling about here. There is a difference between being critical of things and being paranoid.
Science always works with the "best" that's available at the time.
That gives us the "best" way to predict the future.
The only thing that's ridiculous here is you: that you say everything we know is wrong, that we know nothing... that's just not true. There is a lot of knowledge.
And sure the models change now and then... does it really matter? We've to do the best we can with what we know NOW.
We cannot rely on some ridiculous notion that perhaps what we know now is wrong.
A little bit? lol, I don't think you understand what the Golf current does.. It raises the temperature of vast territories in Europe.. And by several degrees. And if it is stopped, well, you can guess what will happen.
LOL there is a difference between not being able to "fucking read", and not agreeing with you just because there are some skeptical scientists that say global warming is made up by the American government or something like this (and every data in the world is fake).
If you were so kind to point out what I missed I would be so happy.
So far none of you provided enough proof to even question the existence of global warming, as this recent small decline is not that strong proof.. And that faking the whole world's data is a true conspiracy theory and I always hated those..
No, you can't read.
If you could, you wouldn't have done a one word quote and given a reply that was completely wrong on the description of what was actually in the post. I explicitly stated that I considered it a likely explanation, just so morons wouldn't go OMG! Creationist! rant rant rant...
Live in your little bubble, I stopped caring what morons believed on this subject when it became apparent I wouldn't have to deal with the impacts of the stupidity of others. Nothing will be done at this point, it fell apart ten years ago and you just haven't noticed yet.
I find this to be offensive against myself, calling me moron several times in a comment.. Calling others bad names will just make your viewpoint even less credible, and I think is against the forum rules of not attacking the other person, in other words, it is plain rude.
I don't really like to quote whole pages worth of comments (I really like to spare space), it's a bad habit, I thought it was obvious that my reply was about that paragraph and the topics in it. Sorry if it caused confusion.
Calling the other side of people morons just because they don't share your beliefs is not a good thing to do, as global warming does have strong evidence (you just try to deny it), no matter how you want to call it to be nothing. And again, judging the whole thing based on the data of a single decade or some colder years is everything but scientifical. You should view the century, but I guess the fake data and other things you said makes this impossible. I will never believe this whole world has fake data on temperatures thing unless it is proven by a world wide committee of scientists.
EDIT: I messed up quotes so I had to relocate some sentences.
Insult by implied association is still insult.
It is not the clever way to get-away-with-it. It's a little too transparent.
Let's not try to be clever. It's unfortunate when you fail.
Is several degrees that much during winter?
I don't think much will happen. Winters will get a few degrees colder, summers won't make much of a difference. But we already have warmer winters than 100 years ago. At worst we'll get back to pre-industrial winters. Maybe I can skate again in the winter!!! That's been a while ago!!! Well actually there was a cold 2 months last year, but it wasn't as cold as 30 years ago when I was young and could skate on the big canal in winter during my birthdays.
The mechanism for stopping the Gulf Stream is a large influx of melt-water, but there are not many reservoirs for melt-water around anymore, there's really only the Greenland ice-sheet and compared to ice-age ice-sheets that one is very, very small. Also, it won't melt all at once or will it? Will that really stop the Gulf Stream?
Also consider that the summer time melting of the arctic sea-based ice-shelf didn't stop the Gulf Stream, while that accounts for a lot of sweet water.
And finally, I doubt it'll start an ice age. The European ice-sheets were an extension from huuuuge ice-sheets in Siberia. There are no such ice-sheets. The summers are too warm for ice to persist. We're only witnessing more and more retreat of ice and permafrost.
That goes contrary to an ice age. I think that an ice age can only start when temperatures are already abnormally low in the northern hemisphere, so that ice sheets can form in Siberia and Canada. When the Gulf Stream stops, it could help form large ice-sheets in Europe and over the North Sea. But the circumstances are no favorable for such a set of events.
After all... a winter in Siberia can have temperatures of -60 degrees celcius in some parts. It is very cold and cold air can carry little moisture (in the form of snow), so every year little ice accumulates. Maybe a few meters at best. In the summer temperatures are 20 degrees or even higher. A few meters of ice are easily melted away in those circumstances. It is very hard to have hundreds of years of sustained cold weather to create a thick layer of ice that can create its own self-maintaining cold climate.
Is hasn't, really. It's just a freak set of circumstances that would normally have led to even LOWER temperatures than we experience today.
Also, the effect of the El Nino is something that's having a cooling effect at the surface of the earth. It transports warmer water down and colder water up. As a result the temperature deeper in the ocean RISES. As a result, there's still a consistent trend of heating of the ocean during the last 15 years, which has NOT stopped but is just going on and on and on.
If you think ahead, what this means is that the NEXT El Nino will have less of a cooling effect, because the deeper waters are warmer than they used to be.
All of this is perfectly consistent with a pattern of global warming. You fail to take these things into account.
Really psychoak, a scientist tries to understand EVERYTHING before making a statement. That's really difficult (almost impossible) so I can understand that you don't do that... but at least give it a serious try. Try to approach the problem from every angle, use as many data as you can and DON'T limit yourself to a few incidents. To get a robus result, it's best to follow long-term trends or averages, so that you don't get sidetracked by freak combinations of factors (on long term those cancel out, but on short term they can give noisy spikes in data).
For christ sake, look at satellite images about huge clouds of smog hanging over China, crossing the Pacific and creating smog in places like LA. If you call that part of natural fluctuations and negligible or whatever you call it ... well I just don't know what normal is in your dictionary. It's a fucking huge event that's there to stay as long as billions of people keep pumping all kinds of waste products into the air. When India, Indonesia etcetera (which have significant coal reserves) follow suit, those clouds will only get bigger and bigger.
Actually that smog helps to keep the planet cooler than it otherwise would've been... and it might even help the formation of clouds by supplying many condensation cores. What some researchers suspect is that, as soon as those coal plants get "cleaner", the world will instantly warm up by a fraction of a degree. Actually cleaner coal plants require more coal because it costs energy to clean up the exhaust fumes.
It can cause a difference.. It is not that simple. The Gulf current makes the climate more stable and predictable, less extremities in temperature levels (no -70°C in the winters and no 50°C during summers, not speaking about the daily amplitude of temperature). As you see, eastwards the max and min temperatures are both rising and decreasing, reaching a maximum around the taigas and continental deserts. And do you want winters like the ones in Siberia? I guess not
Oh and poor Norway would have winters 30°C colder than today.. I guess that is a difference.
Truth is noone knows what is the real cause for glacials, there are only guesses. My favourite is the one that says if we reach a specific value of global average temperature, the thermohalic conveyor belts will stop, causing massive cooldowns in the northern hemisphere. Though you are right, it would need much time to form those huge ice sheets, but longer cold periods will do it, right? I doubt the ice sheets and mega glaciers of the Pleistocene were formed under a year or two..
But again, do we really want to experience what causes a new Ice age? I think not, but currently we are heading towards that direction.
Some say Ice ages are connected to the properties of Earth's orbit. But how comes that Ice age periods are extremely rare and not permanent? I only know about 3 major cold intervals, the Pleistocene, the one around Ordovician (400?) or something, and the Snowball Earth period 700 (?) million years ago.
http://en.wikipedia.org/wiki/Timeline_of_glaciation#Known_ice_ages
Wiki says there are 5 known glaciation events, but these are not continuous, and there are huge intervals not having any glacial periods.. I find it to be strange.
I seriously doubt that. Norway gets its warmth from the western winds from the ocean. Unless the ocean completely freezes over all the way down to the North Sea, Norway will stay relatively warm because of the warm sea water.
The other ingredient necessary I think is low levels of CO2, and already-low temperatures especially during the summer.
I think it would take a long time, and especially that it would require at least a few years of very very cold summers so that ice sheets can say, grow bigger (and not melt away). Maybe because of a period of intense volcanism.
There were many in the last few million years.
It's associated with low levels of CO2 (below 300 ppm, and hence low global temperatures).
Earlier in history, CO2 levels were generally higher.
They're not permanent because... well I think that a CO2 build-up increases temperatures slowly, until a tipping-point is reached and ice-sheets start to melt rapidly, setting a feedback in motion.
I'm not sure why the CO2 would rise. I suspect a disruption of the carbon cycle.Water levels are lower, exposing (and eroding) swamps and peat, which are decomposed into CO2.Also, less plant life means less CO2 that can be buried, thus naturally released CO2 from volcanism could stay in the atmosphere longer.Also, CO2 could be released from the oceans as temperature rises, which could provide a sort of feedback effect.Also, Milankovitch cycles could assist this process by making the summers in the North warmer, just like they assist in triggering an ice age by making the summers in the North colder. Maybe it's a combination of things.
Yes that was freaky.
It's amazing that life survived under such conditions!
That's our current situation. We're experiencing low levels of CO2 during our era, compared to much of the time before. Temperatures are simply much lower than they used to be.
That one was probably triggered by an extreme drop in CO2 levels (and hence, global temperatures) due to the formation of the Appalachian mountains.
http://www.scientificamerican.com/article.cfm?id=appalachians-triggered-an
The Karoo Ice Age.
http://en.wikipedia.org/wiki/Karoo_Ice_Age
It looks like that was also taking place during a period of low CO2 levels and fairly cool global temperatures (comparable to pre-industrial levels).
And that is one event, the pleistocene (or neogene) glaciation. All had glacials and interglacials, but these are grouped, you never see a single glacial anywhere, only a group of them following each other in a short interval (short in geology).
Everyone seems to underestimate life.. I think it is impossible to be destroyed, if there are bacteria in rocks as deep as several kilometres..
Lol nope. Peistocene ended around 10000 years BP, today we live in the Holocene (or anthropogene, but this is not a mainstream category).
Maybe tomorrow I will provide a longer response as those links seems to be interesting but I need sleep sometimes
Edit: GG on broken postings...
Transparent is when I told you I really don't give a shit whether you ban me or not. Clever is how you pretend I care and throw your own insults while standing on your high horse.
I'm never going to be nice to people that willfully misrepresent what I've said while trying to prop up their own delusions, yours included. Political correctness does not interest me, following rules I disagree with does not interest me. Since this is apparently a problem for you, get it over with already.

It's now official.
Bah! It's a Tea Party conspiracy funded by Koch brothers money and given cover by Fox News.
It can't possibly be that the "experts" and their "models" got it completely wrong, can it?
For reference: NOAA Prediction NOAA Actual (Daiwa's link)
To be more specific, for the 2013 season, the NOAA predicted 13-17 named storms (13 were actual) and 7-10 hurricanes (2 were actual).
So?
Actually the predictions (actual) were 13-20 (13), 7-11 (2), 3-6 (0) - Named Storms, Hurricanes, Major Hurricanes. So we had essentially the average number of named storms and significantly below the average for both hurricanes and major hurricanes. This after NOAA predicted an "Active or Extremely Active" season and "the era of high activity continues".
But they were close, right? Because 7-11 is close to 2 and 3-6 is close to 0. Besides, I'm sure if the numbers were flipped and the storms were significantly more active this season, everyone would be acting like it wasn't a big deal right? No one here (or out there in the AGW industry) would be jumping up and down about how even the predictions of an active season weren't good enough and things are getting worse faster than expected. Surely that wouldn't have happened had the situation been reversed right? I mean, it's not like this industry to cherry pick only the data that supports it theory.
In reality, as far as these sort of predictions go, they missed by miles. AGAIN.
But lets invest trillions of dollars globally all on the word of these folks' ability to predict the effects of climate change over the next fifty to one hundred years. I mean, it has got to be less complex than predicting the hurricane season for the same year you are in, right?
Actually, for the 2012 season the NOAA (as well as the roughly 1 dozen other organizations that prepare forecasts/predictions) under predicted the activity fairly significantly. Skill is determined in averages over decades though, not single year forecasts. Hopefully they'll get more accurate over time - it's definitely a complex thing to be attempting to predict. I'm not sure how you make the leap from predicting the future of storms in one area of the world to what has been (present perfect) observed to date with the entirety of AGW though. Emotions and ideology (politics) might be interfering with your analysis there but I can't be sure.
If that's all true, and I have no reason to doubt you*, what is the point of making single year predictions at all? I'd rather they just admitted the obvious and remained mute.
*Edit: NOAA simply "predicted" the prior 30-year average for 2012, then upped the ante for 2013, based on what it's unclear.
Okay, for one, take your "emotions and ideology" nonsense and stick it up your ass. How's that for emotion?
That's just typical progressive bull shit to pretend you're rational and scientific while anyone who disagrees with you is an ideologue and emotional as a way to delegitimize whatever they might say without having to actually discuss their points. It's a childish debating tactic that's been tried over and over in this thread. So how about we just admit you have no idea what my motivations are and I'll agree the same about you, we'll take each other's comments at face value and we can continue a discussion that should be enjoyable rather than playing dumb-fuck superiority games, huh?
Now, back to the point.
You're telling me that inability to accurately and reliably predict the behavior of a subset of the global climate system in the short term doesn't imply anything about the reliability of those same people to predict the behavior of the entire system over the long term?
Your point about 2012 doesn't help your cause. It reinforces my point. If you, general you, not you Ekko_Tek specifically, don't understand the system well enough, or have it modeled well enough, to make reasonably accurate predictions over the short time horizon why on earth should we upset the global economy based on your predictions about the same system over the long term? Especially given that the long term predictions involve even more complex inputs than the short term version?
And you ignored my main point. I'm sure that if this season had been especially active, well above the predicted amount, you and others wouldn't be jumping up and down about our "dire straits" and telling us how we have even less time than we thought and yadda yadda yadda, right? Or is this a case of the year to year prediction variance doesn't matter because, in this case, it hurts the AGW argument? Or what? Because I can't believe that the AGW industry wouldn't be making mountains of this season had it been more active than expected. You might not. I don't know you and have no idea, but this industry has a history of cherry picking data based on what it wants the narrative to be (which is part of the reason I don't blindly trust "Well the IPCC said...!!!").
So essentially, your main point then was just an assumption about other people's thinking while complaining that people are making assumptions of you?
Kantok, mentioning emotions and politics is not me being petty. It's unfortunately a hugely significant and interfering factor in people being able to understand these issues - because they are unable to leave their baggage at the door and look at things clearly. I meant it fairly lighthearted in my post to you but I understand it's a pretty heated thread and the written word conveys things pretty obliquely. No offense intended but your point was very unclear to me. AGW is saying that our activities are heating up the planet and changing the climate, sometimes in unpredictable ways. To me, it's pure denialism on the level of creationism, faked moon landings, truthers, cigarettes don't cause cancer, vaccines cause autism, whatever conspiracy based, evidence free, anti-science issue du jour you want to choose from to say otherwise. It's based on data that currently exists and that there is widespread consensus on. Predicting the future is different and, while it can be helpful if it's accurate, it's obviously different from current facts and captured data. The IPCC does not give a fuck about what happens or doesn't happen in a single season in the North Atlantic. Neither do I. As people have repeated over and over, it's about long term and global trends - not about how cold the winter was this year in Donnybrook, North Dakota. The IPCC is actually quite conservative in its reports compared to others.
OK
Yes, those are 2 different things.
The long term trend doesn't have to deal with short-term effects, which are by their nature unpredictable because climate is a chaotic system.
On the long term, short term effects cancel out so you can indeed make general statements about future climate in general.
That doesn't mean that models are completely different from reality btw. As far as I understand, models can create storm systems that resemble a real climate system. But because the climate is s a chaotic system, you cannot predict when or how many storms will occur in a particular year. You can only look at the statistics of the results - like how many storms there will be in an average year.
As far as the storms are concerned, it's not known what will happen. Some studies indicate fewer storm, but each being somewhat stronger and especially having more precipitation because they can hold more moisture at higher temperatures. It's hard to predict exactly what will happen with large storms, because they are so complicated and their formation depends on things like wind shear.
The strong winds from Africa prevented big storms from forming this year. It's not possible to include such an event beforehand in models. If it's included afterwards as a known feature, then it can be used to test models. But only in hindsight.
Some people may think that this is a useless excercise - why would you want models if they can only model the past in detail? Well that's because if they can model past events reasonably well, then the models can be used with more confidence to make statements about the average (statistical) properties of future climate. You can run hundreds of simulations of the model for 100 years into the future, and analyze all of the results put together. It won't tell you anything about what "will" happen exactly in the year 2100 because some runs of the model may predict a quiet year, others may predict a violent year, but it can tell you what we can "expect" to happen around that time (given assumptions about how fast the earth will warm up, and such things).
1: Chaotic effects canceling out in the long term is a major assumption.
2: Some of those short term effects that we, as a species, suck at predicting matter in the long term.
But really, you're making my point for me by arguing that we can't predict some things beforehand and can only create accurate models after the fact. Climate is a hugely complex system that we don't fully understand yet. Even if we did fully understand it we don't have the computational power to accurately model it without making a series of huge assumptions. Even if there is random walk year to year, those assumptions and those small effects that we can't predict matter to the climate system. Which means they matter to our long term predictions. If we don't know enough climate factors to predict strong wind shear from Africa or atmospheric patterns that produce exception dry, sinking air six months from now how on earth can we reasonably say that we know enough to predict how the system will react to assumed inputs over the next 50 years?
if you can't accurately model the smaller problem, then you can't accurately model the bigger problem without making FURTHER ASSUMPTIONS about the inputs you clearly don't understand and about the behavior of the smaller problem which you've already shown an inability to forecast accurately.
You misunderstand... the climate models CAN simulate realistic storm systems.
It's only impossible to predict exactly what happens a year into the future, because of its chaotic nature.
You can still derive meaningful things about the future from the models, in a statistical sense. You can say for example something like that we expect that on average storms will be stronger and bring heavier rains.
That doesn't mean that every storm will be like that, or that there will even be many storms in a given year. You can show a trend.
You HAVE to make a distinction between forecast and accuracy/reliability of a model.
A forecast a year in advance is IMPOSSIBLE no matter how good the model is. Even if you have an exact replica of the earth/sun/moon you cannot make such a forecast. Put 2 earths next to the other, wait a year, and they'll have different storms.
The one thing you can "predict" is the chances of more or less severe storms occuring over the next decade. That's not an exact prediction, because an exact prediction is impossible. There's always a chance that every year in the next decade has no or few storms. But at least you can place some numbers on that chance.
You are wrong about this, too. Models are never perfect and they can be off a little bit.
This doesn't mean that they are completely wrong. Statistically speaking, they can still produce valuable data, even if every storm they produce is slightly off. That just doesn't matter, models always have some flaws. The only thing that matters is, that they are reliable enough to give us reasonably reliably insight in what kind of weather patterns we can expect. We don't need exact details.
I never said it was you being petty. I said it was you trying to invalidate my points without having to address them by pretending to be the only one concerned about cold hard logical reality which is what you were doing and what you continue to do in the quoted paragraph. It is the exact same fucking thing as if I said you are clearly an AGW True Believer who sits at Al Gore's feet licking his toes while spoon feeds you his (money-making) "climate science" and therefore anything you say is akin to religion and can't be taken on a factual basis because you are clearly blinded by the wonderful tasting kool-aid flavored lotion Big Al uses on his feet.
Now, I didn't say that because for something like this discussion to function there has to be some level of acceptance that the other person is open and honest about their beliefs and motivations.
You can keep calling it "akin to creationism" and "pure denialism" all you want, but you are either not reading what those "deniers" are writing or you're purposefully missing the point. Disagree and debate all you want, but stop pretending that nobody but you has a valid point.
If this is about long term and global trends, then you need to show that you understand the system well enough that your long term outlook can be trusted. So for climate scientists haven't done that. Their "models" from a decade ago about where the temperature would be this year were off. Badly so. But rather than acknowledge that people scream that anyone who points it out is a denier.
Likewise, the IPCC is a political arm of the most highly politicized and corrupt international body going. Pointing that out and saying that it's worth keeping in mind when discussing their "findings" is met with... wait for it... screams of "DENIER!"
Asking about why some data was faked to make it fit the models over the last 20 years is met with... screams of "DENIER!"
Asking AGW proponents what they propose to do to fix the problem, assuming they are right (which I don't) is met with sputters of nothing or screams of "DENIER!" or calls for giving some select few group of "experts" the power to do whatever they deem necessary to solve this problem.
And on and on and on.
As I've said before I'm suspicious of AGW because
Now, all that said, I'm skeptical of AGW. I don't deny that climate changes, because it certainly does. I don't deny that man contributes to it, because we certainly do. My problem is with the immediacy of it all (we have barely 100 months to save the world, according to Prince Charles) and the complete willingness to toss actual scientific method out the window in the name of expediency and consensus.
And finally, as Brad has said a few times: How do you solve it? Let's stipulate that everything you, Ekko_Tek, have said and believe about AGW is true. How do you realistically solve it. Describe the scenario that can plausibly happen in today's world that solves this problem you think exists.
No, you misunderstand. It is our inability to predict when storm systems will happen and what will cause them that is my chief concern. If we don't know the climate system well enough to make those predictions how can we predict effects of CO2 on the global system over a hundred year time span. The only way that happens is by making assumptions about things, which we are clearly not good at otherwise our short term record would be better.
We simply don't know the system well enough yet.
