Riduna at 07:19 AM on 24 June 2011The chief troupier: the follies of Mr Monckton
Professor Garnaut can express his own views on being dubbed a Nazi because of his acceptance of consensus science on global warming. The kindest thing that can be said of Monckton, who makes this disgraceful slur is that he displays the same inexcusable ignorance of history as he does of science. Monckton was not even born during the fascist regime so, unlike me, has no first hand knowledge of what it stood for or the terror it inflicted on those who fell foul of it. Possibly that is why he so carelessly smears those who do not agree with his false beliefs on matters of climate science. While I defend the right to freedom of speech, even when abused to express repugnant views, I do question whether we need to welcome a foreigner to Australia to repeat the litany of lies, misrepresentations and distortions of climate science for which Monckton is so well known. -

Sphaerica, from what I have read about fish and fish stocks (both getting smaller - which would probably also impinge on fish-stock used in cooking, but that's going too far off-topic), the so-called skeptics would have a hard time trying to claim that fish are actually getting fatter and displacing more water, thereby causing sea-level rise - and a rise in seal levels too, obviously, who would also get fatter and displace even more water ! But I won't hold my breath. -

Eric the Red at 07:07 AM on 24 June 2011How would a Solar Grand Minimum affect global warming?
Yes, to your first premise. I am not referring to the people mentioned, but rather the media at large. While there are some science writers for various circulars, the larger reporting arena is largely ignorant of any science beyond the high school level (and that may be a stretch). A quote from a scientist is enough to solidify any story. I am not naive about the agendas regarding the science. There is enough name-calling, mis-information, and scientific rebutals to other journal articles to fill an encyclopedia. There are times when it seems that half the articles in a particular journal are a direct response to previous work. A solar minimum (whether it is grand or not) will be a boon to astrophysicists. Whether it becomes exciting to others will depend upon its effects. -

22, Albatross,Who would have thought that,in the very distant past, Fourier and Arrhenius were plotting to use the radiative trapping properties of CO2 in forward their agenda establish world governance and fascism? ;)
You have no idea how closely you have struck to the truth! The following quote from a biography of Arrhenius was posted in a comment on Nova's site:“Svante Arrhenius was also actively engaged in the process leading to the creation in 1922 of The State Institute for Racial Biology in Uppsala, Sweden, which had originally been planned as a Nobel Institute. Arrhenius was a member of the institute’s board, as he had been in The Swedish Society for Racial Hygiene (Eugenics), founded in 1909. Swedish racial biology was world-leading at this time, and the results formed the scientific basis for the Compulsory sterilization program in Sweden, as well as inspiring the Nazi eugenics in Germany.”
I actually think poor Jo Nova is discovering the reality behind the saying "Lie down with dogs, get up with fleas." She tried a while ago to convince her bleating followers that GHG theory does not violate the 2nd Law of Thermodynamics, and that arguing otherwise makesdeniersskeptics look silly. The barrage of 1000+ comments refuting her stance was laughable. Now, in trying to take a mature and balanced view of Monckton (even, laudably, going so far as to find fault with his two faced "apology"), she's encountering more of the same (as evidenced above) -- a bevy of anti-climate crusaders who think that Monckton's only mistake was in not going far enough with his parallels. -
Bob Lacatena at 06:42 AM on 24 June 2011Sea Level Hockey Stick
62, skywatcher, Yes, but you have not yet proven that fish are not simply getting fatter (and so displacing more water), no doubt a result of all of the greenie fishing restrictions being placed on the poor, struggling fishermen throughout the world. If scientists would just study this, they'd certainly see that climate change has nothing to do with rising sea levels. It is, in fact, fatter fish which in turn displace more water, and this is, in turn, due to a chronic under-fishing problem which should be corrected immediately, before the problem reaches catastrophic proportions. -

From RealClimate's post on the paper: "These data are valid for North Carolina, where they are also in agreement with a local tide gauge (green)(Fig. 2 in the paper). But they also agree with another proxy data set from Massachusetts. Sea level changes along the US Atlantic coast do not need to fully coincide with global mean sea level, however. Even though the level rises uniformly if I fill water into my bath tub, the ocean has a number of mechanisms by which local sea level can deviate from global sea level. One of these mechanisms can also occur in the tub: the water can “slosh around”, in the oceans on multidecadal time scales. And there are some other factors as well, like changing ocean currents or changes in the gravitational field (due to melting continental ice). In the paper these factors are estimated and it is concluded that the North Carolina curve should be within about 10 cm of global mean sea level." Also, Stefan (an author on the paper) writes this in reply to this comment: "[Response: That is discussed in great detail in the paper, but also in the post above. We estimate that the NC data should track the global mean sea level to within +/- 10 cm (on the time scales we resolve), and so far nobody has challenged this estimate. Specifically, Jens Schröter, quoted in the Spiegel article, has confirmed to me that he also finds this a reasonable estimate. -Stefan] [My bolding] -

Argus, This really isn't worth the time it takes to type it, but if sedimentation were any factor in sea level rise, it would be an ongoing one, uninterrupted from the beginning of time. You'd see a steady sea level rise throughout all of recorded history. Or do you have some reason to believe that climate change accelerates sedimentation? -
skywatcher at 06:35 AM on 24 June 2011Sea Level Hockey Stick
Good info well found Andy S. So the upshot of it is that the volume of water increase through melting / thermal expansion is at least two order of magnitude greater than the volume decrease through sedimentation. I think we can safely say that sea level rise is not an artefact of sedimentation changes... -
Andy Skuce at 06:30 AM on 24 June 2011Sea Level Hockey Stick
Argus@51, good question: According to this Skeptical Science blog post the world's rivers are dumping 28 billion tonnes of sediment into the ocean, which is about five percent of the weight lost by melting Greenland ice . Remember that the sediment has a grain density of about 2.5 times that of water, so the volume it displaces is only about 2 percent of the volume added to the oceans by Greenland ice melt. A significant fraction of the world's water is stored in man-made reservoirs, which, according to this newspaper article, has reduced sea-level rise by 30 millimetres. Considerable sediment is also being held back by dams, which diminishes the amount getting to the sea. -

I'm interested to see where you are going with this. Mainly from a communication perspective, although the style is engaging enough to have me interested in the material too. -
KR at 06:24 AM on 24 June 2011Sea Level Hockey Stick
Argus - Keep in mind that sediment, being essentially ground rocks, will have a much higher density than water; therefore it will require much more sediment than water to equal the same volume. Sedimentation may have increased due to anthropogenic activities (farmland erosion). I don't know how those numbers, though. However, I will note that contrary to increased erosion via land use, waterway control aka levees, damns, etc., have reduced the sedimentation levels at river deltas around the world. This is part of the water problems in New Orleans - which is really sad, I love that city. Waterway control has reduced delta deposition over the last century or so, causing increased subsidence of the delta around New Orleans and increased storm risk. Alexandria in Egypt has some of the same issues. This reduction in river sedimentation should decrease the rate of sea level rise. But I wouldn't claim strong changes in either direction without more data. -

Norman - "or the purpose of showing how a hazard becomes a disaster and pointing out that the number of actual hazards does not translate into number of disasters". Okay, I understand. However, while the a bad storm doesnt turn into disaster, an increase in bad storms surely increases the probability of a disaster. -

Argus at 05:51 AM on 24 June 2011Sea Level Hockey Stick
#51, Thanks for the link to Poe's law, I didn't know about that! I suppose you are sarcastic, but I simply wanted to compare the effects of erosion and melting on the sea level. "From the Yellow River, over 1.6 billion tons of sediment flows into the ocean each year." (en.wikipedia.org) "552 billion tons lost from the Greenland ice sheet in 2007." (answers.com) "In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place." (en.wikipedia.org) So, 1.6 billion tons of sediment from one river. What could be the total amount in the world? 160 billion tons maybe? It would replace about 50 billion tons of sea water. It would still be considerably less than the water from Greenland ice, but at least it is in the same league. I welcome better figures and better calculations!Response:[DB] Having been Poe'd before, I was genuinely curious.
Dunno about that answers.com number you quote. Greenland ice mass loss increased from some 200+ billion tons in 2009 to about 600 billion tons in 2010. See here. And that is only part of the glacial melt picture every year.

Albatross at 05:48 AM on 24 June 2011Linking Extreme Weather and Global Warming
EricS @180, "The outflow boundaries, lake breezes, etc are a dime a dozen and do not provide the pool of dry air nor the long range winds to advect dry air into a moving supercell to cause strong tornadoes." Nonsense, as someone who works in this field I am confident in saying that you are really talking though your hat. Read this, one of the et cetera above should have been HCRs. Now you are just doing what EricS is doing. If a supercell ingests dry into its updraft it is done. I have seen this happen first hand. And you need to read up more about the "dryline". -
Eric (skeptic) at 05:33 AM on 24 June 2011Linking Extreme Weather and Global Warming
Albatross the seasonality of violent tornadoes is ample evidence that they require the springtime jet (which is both strong and late this year) and dry air availability from Canada or east of the Rockies. The outflow boundaries, lake breezes, etc are a dime a dozen and do not provide the pool of dry air nor the long range winds to advect dry air into a moving supercell to cause strong tornadoes. That isn't to say it can't happen. Aligned winds in the atmosphere can push a solitary MCS 1/2 way across the country with embedded supercells (no front or low needed). Otherwise something has to advect the dry air eastward, and I think the Great Plains LLJ is mostly south to north. -

From Camburn's link in 54: "The current sea level trend of about 1.7 mm/y" The current sea level trend is about 3 mm/y. The trend has increased over the 20th century; you can't just use the 20th century average without taking the acceleration into account. -

EricR @178, "The greater the energy gradient at that layer, the greater potential for tornadic activity." Sorry, but no. Eric, you seem to be trying to make it sound that you know what you are talking about but the more "information" you volunteer the more apparent it becomes that you do in fact not. And you have still not backed up your assertions with anything from the reputable scientific literature. If you like I could direct you to some literature on this subject. -

Yes, the severe storms occur at the boundary layers. The greater the energy gradient at that layer, the greater potential for tornadic activity. -

EricR, "In a way, yes" I do not know to what you are referring. My claim that you may be feigning ignorance? Please do not get confused between media sensationalism and a very deliberate attempt to distort, confuse and misinform. You seem quite naive about the agenda against science and the theory of AGW that "media" people like Delingpole and Gunter and Solomon and Bolt and Limbaugh have. These guys are excited alright, but not for the reasons you think, they are excited because science stories like this allow them the perfect opportunity to distort, confuse and misinform the public about the theory of AGW. -

Are you countering with your own quote mining? Recent decades is a far cry from 2000 years. "What happened in time periods of 300 and 400 years is highly contentious," No emphasis needed.Response:[DB] You continue to twist Latif's comments out of context to fulfill your goal of fostering doubt by conflating dissent over minutia into broad overall disagreement. Latif in the article clearly agrees with Rahmstorf for the overall period of the study (calling it a strength) and that the blade of the SLR hockey stick is not accidental. Latif and Rahmstorf differ in interpretation of details: that's science.
Schröter, OTOH, is arguing for a presence of continental drift being a player over the 2000 period of the study without presenting supportive evidence.
At least you are consistent with your narrative.
-
Eric the Red at 04:21 AM on 24 June 2011How would a Solar Grand Minimum affect global warming?
Albatross, In a way, yes. I would place the blame more on the sensationism of the media. Afterall, what makes a better headline, "A return to the temperatures of the 70s," or "Another Little Ice Age is on the horizon?" The media is largely scientifically ignorant. Most reporters cannot distinguish between a scientific expert and a science fiction writer (no slam intented towards those writers who are science experts). The same does occur in the other direction; remember the big media portrayal of the "Barbecue Summers?" Incremental changes, even over long periods, are too mundane for the average reporter. But someone making a claim of extraordinary proportions (regardless of the probability) raises the excitement of the media. -
Albatross at 04:00 AM on 24 June 2011Linking Extreme Weather and Global Warming
EricR @175, Your opinion regarding the shift may be correct. You are, however, overstating the importance of cold fronts in triggering severe storms, and understating the importance of the great plains low-level jet (a barrier-type jet attributable in part to the sloping terrain and differential heating of the terrain, not a baroclinic jet). Severe storms can be triggered by outflow boundaries, drylines, trofs, sea breezes, lake breezes etc., just read the SPC mesoscale discussions. Wilson and Schreiber (1986) found that 80% of that of all thunderstorms in their study area were triggered close to mesoscale boundary layer convergence zones. Other researchers have made similar findings on the importance of mesoscale surface features in triggering severe storms. It is worth noting though that the great plains low-level jet is modulated to some extent by synoptic-scale features. "While an increase in moisture would serve to enhance development, any decrease in the cold, dry air would counter that effect, and simply produce heavier rains." Again you are placing undue focus on cold fronts. Care to back it up with something from the reputable scientific literature? To some it up, while I admire your efforts to speak to this stuff (and you do appear to be making a sincere effort), your unsubstantiated musings do not carry much weight I'm afraid. -
JMurphy at 03:50 AM on 24 June 2011The Last Interglacial - An Analogue for the Future?
To a so-called skeptic, the immediate reaction will be : "See, temperatures have been higher in the past - where were the SUVs ? That 'proves' that it's not us." Or : "See, things weren't that bad - 'we' got through it then, we'll get through it now." Or : "All that lovely warmth. Cold kills, you know." -
Eric (skeptic) at 03:40 AM on 24 June 2011Linking Extreme Weather and Global Warming
Eric (the other): seasonality of strong tornadoes would also be a key CC indicator for me. That's the first thing I looked at this year and there was nothing particularly early. My first link in 166 shows no seasonality change either. Unlike other CC impacts I think we are very early in the game. When we see heat and humidity like the deep south up in Canada, then we could see a new tornado alley up north. -

Rob Honeycutt @23, Lubos Motl is very full on, actively endorsing both the Nazi comparison and the use of imagery, which he attempts to emulate. Interestingly he cites Tony Abott as making the same points as making the same points as Monckton, though presumably without the direct reference to Nazism. Anthony Watts position is more subtle. He approves the Nazi comparison, but disapproves the use of the image of the swastika and saying "Heil Hitler". In other words, make as odious a comparison as you like - just don't give people adverse talking points. Of the two opinions there is little to be said in their favour. The most that can be said is that at least Motl retains the virtue of honesty. -
Eric the Red at 03:24 AM on 24 June 2011Linking Extreme Weather and Global Warming
Albatross, The Great Plains are definitely ripe for tornadoes, as they bring together the warm, humid Gulf air and cool, dry Rocky Mountain air. A weakened of the jet stream or a shift northward would lessened the impact of these two air masses. While an increase in moisture would serve to enhance development, any decrease in the cold, dry air would counter that effect, and simply produce heavier rains. Not that I am claiming that we know enough aobut tornadoes, but temperature and moisture gradients are very important to tornadic updraft development. My opinion (note word choice) is that the timing of othe tornado season may shift based on changing temperatures, but that the tornado locations are unlikely to move much. (FWIW) -
Albatross at 03:19 AM on 24 June 2011How would a Solar Grand Minimum affect global warming?
Eric @94, "I was not aware that anyone was predicting an ice age" I can only assume that you are feigning ignorance here. Of course the reputable scientists and people who know what they are talking about are not making such silly assertions, but you and I both know that is sadly irrelevant for the denial/"skeptic" misinformation machine. The very existence of this post is because of the ludicrous claims being made by "skeptics", contrarians and deniers of AGW. From the main post: "This has climate skeptics speculating that solar 'hibernation' may be our get-out-of-jail-free card, cancelling out any global warming from our CO2 emissions." Also watch this video by Hadfield and follow some of the links in this article. -

While Rahmstorf is convinced that his findings represent global changes, Schroter and Latif are not. http://www.spiegel.de/international/world/0,1518,769687,00.htmlResponse:[DB] Perhaps in your quote-mining efforts you could read Latif's whole quote:
Satellite images offer proof, though, that sea levels have risen significantly in recent decades. And this development occurred exactly at the same time as industrialization and the rise in air temperature. It would be "hard to argue" that that could be accidental, Latif says, thus siding with Rahmstorf.
Emphasis added.

Rob Honeycutt at 02:49 AM on 24 June 2011The chief troupier: the follies of Mr Monckton
Albatross... It's interesting because initially Watts condemns Monckton for what he's doing here. But as you read down into the comments you realize that that condemnation is very thin at best. Lubos Motl has a long comment on how Monckton is actually correct in his statements, which Anthony follows up to confirm. -
Albatross at 02:45 AM on 24 June 2011The chief troupier: the follies of Mr Monckton
Rob and Sphaerica, agreed. Who would have thought that,in the very distant past, Fourier and Arrhenius were plotting to use the radiative trapping properties of CO2 in forward their agenda establish world governance and fascism? ;) Unless Anthony Watts unequivocally condemns Monckton, I think it safe to assume that Watts agrees with Monckton's position. In short: MONCKTON = AFA = WATTS = LINDZEN Remember too that Watts in the past has on a couple of occasions allowed Monckton to use his site to launch vitriolic attacks and threats against scientists. -
Albatross at 02:36 AM on 24 June 2011Linking Extreme Weather and Global Warming
Tom @164, Thanks for that interesting post. I followed the link to your top graphic and the links therein. Here is the link to the Munch Re report for others who are interested. And that led me to this interesting paper by Kaltenböck et al. (2008). They conlcude: "2) Low level moisture can be used as a predictor to distinguish between significant tornadoes or non-severe convection." And "While deep-layer shear discriminates well between severe and non-severe events, the storm-relative helicity in the 0–1 km and especially in the 0–3 km layer adjacent to the ground has more skill in distinguishing between environments favouring significant tornadoes and wind gusts versus other severe events." These findings corroborate other research for the United States on tornadic environments, and the increase in low-level moisture is particularly pertinent to AGW, as we know that (globally) low level atmospheric moisture is increasing and will continue to increase, and that lower cloud base heights are typically associated with tornadoes. Some are of the opinion that the predicted weakening of the jet stream will weaken storm potential, and in some regions it may. But as I have argued elsewhere, tornado alley is unique because of the presence of the great plains low level jet which is oftentimes critical in producing the high low level critical wind shear (0-3 km and 0-1 km AGL) which are typically observed in environments that produce tornadic supercells. So the predicted weakening of the tropospheric jet stream may not be as significant over this region as some might think. Brooks and Dotzek (2008) noted a marked increase in the incidence of hail reports since the early eighties for hail having a diameter of 7 cm or more. -

Eric, the longer you delay the more expensive action becomes. At present effective action will cost between -1 and 3% of global GDP. If you wait five years that will shift downwards. If you wait ten years it will shift further down, and you will need to undertake geo-engineering to bring CO2 levels below 450 ppm and to keep temperatures down while you do it. At that rate it does not take long before costs exceed 5% of GDP, ie, the World will have a significant negative net economic growth which will be needed to be sustained for decades. That is another way of saying it just won't happen and we will bear the brunt of even greater overall costs because some people are fortunate enough to avoid them. -

19, Albatross, Oh, my goodness. I didn't take your warning to heart, and watched both videos. Now I have to go shower. Really, this is a champion of the denial movement? How is his behavior not disowned by every rational person on the planet? How is a quick and remorseless apology in any way acceptable considering this is his third such (taped) offense? (I say remorseless because while he throws the words "unreserved apology" in there, he immediately goes on to the attack, as if he and his are the victims of a crime even more heinous... his words were "[those] who say we should be tattooed with our opinions, or imprisoned, or barred from Australia, or tried for ‘high crimes against humanity’?” At the same time, he repeatedly accuses "greenies" of killing millions through pushing renewable energy policies, while ignoring the deluge of science that says the drought and other aspects of climate change really could do just that, and more, if left unchecked for too long.) Who here, or anywhere, considers themselves to be rationally skeptical and yet can listen to his stuff and not simply be embarrassed to be even remotely associated with his positions?

48, JBob,One final point, while the land surface can be measured for uplift, what is the sea floor surface doing?
42, Ken,Therefore the volume of the tub must be accurately known for sea level changes to be an accurate measure of warming.
You've got to be kidding me. Is this really going to become a serious "skeptical" argument for doubting sea level rise? That the ocean basins themselves may be shrinking? This is just getting too bizarre for words. -

The Elie tornado was the first confirmed F5. A couple others may have reached f5 status, but were unconfirmed. If we started seeing one a decade, that would be a significant increase. Since there has not been an increase in violent tornadoes in the US, I suspect that we will not start seeing one in Canada either.
