michael sweet at 21:58 PM on 30 January 2011Latest GRACE data: record ice loss in 2010
John@23: It is not yet known how to extrapolate melt rates into the future. Will melt increase 100 Gt per year or will melt continue to double every 8 years? That is the difference between 0.5 meters of melt by 2100 and 5 meters of melt. There is no consensus of what will happen. Some scientists believe that there is a maximium rate of melt (about 2 meters/century) while others think the ice could disintegrate by a rapid wet process (5-10 meters/century). That is why this data is so important. The West Antarctic ice sheet is especially vulnerable to rapid disintegration. Stay tuned for updates! -

Agnostic: Cliff Ollier is a geologist, not a climate scientist. Linking to an opinion piece by a geologist is not a scientific way to support your position. Try to find a peer reviewed paper, I suggest you look at material that is at least 10 years old. The IPCC AR3 might support that position. It is wrong. Scientists used to think that it would take centuries for the ice to respond to increasing temperatures, but that has been proven incorrect in the past 5 years. The ice has responded much faster than expected. That is the point of this post. See my link at #19. Fydijkstra's link at 7 shows substantial surface melt above 1500 meters, which was not expected yet. At 1500 meters they lost 50 cm of ice last year. It is now known that the ice responds rapidly to hot ocean water around the pheriphery of the ice sheet. Scientists are trying to determine how strong the response will be. There is more CO2 in the air than at any time in the past several million years. Why would you expect the ice to respond the same? Only 100,000 years ago, within your 750,000, sea level was 6-9 meters higher. Good bye Bangladesh and Florida. We are hotter now so we expect the sea to rise higher. How much and how fast is still to be determined. Pray James Hansen (who IS a climate scientist whose work is peer reviewed) is wrong this time and the rise is not 5 meters by 2100. -

John, thanks for this update. In a sketch, extrapolating this trend to 2015, I found the net annual mass loss rises to something like 700Gt - equivalent to about 2mm of sea level. Would it be possible to invite your informants to perform the calculations to show what this trend would produce over another couple of decades? I don't really know, but I'd guess there are no known processes capable of retarding the trend, but several conceivable ones which might accelerate it. I'd be interested to know if the GRACE data is indeed disclosing a lower bound for estimates of Greenland's contribution to sea level rise up to 2030 or so. Thanks again for your good work.

Students produce work as they are guided. Pirate claims this is student work, but the survey reflects directly the points that he has emphasized in his postings at his first post here. The graph they used is the same one he first posted!! If Pirate emphasizes in class 400,000 year old data that shows natural changes and then asks is current change natural his students will follow the same pattern. Then the students will show up here and say "My high school environmental teacher said" and they will have to unlearn what they were taught. It is hard to unlearn false data. -

Riduna at 18:46 PM on 30 January 2011Latest GRACE data: record ice loss in 2010
fydijkstra @ 7 I think Professor Cliff Ollier might support your view. In a recent article (http://www.onlineopinion.com.au/view.asp?article=11212&page=2) he states that “There is no melting in the interior of ice sheets - it is far too cold. The centres of the ice sheets, occupying basins, flow only at the base, warmed by geothermal heat and driven by the weight of the overlying ice. There is no direct flow of the near-surface ice in the centre of an ice sheet to the outflow glaciers. It is fanciful to conclude kilometres of ice can suddenly melt when the records show no melting whatsoever in the ice sheet accumulation areas. After considering the evidence of three quarters of a million years of documented continuous accumulation, how can we rationally accept that right now the world's ice sheets are collapsing? Johannessen and colleagues analysed satellite data on the Greenland Ice Sheet from 1992 to 2003. They found an increase of 6.4 ± 0.2 centimetres per year in the vast interior areas above 1500 metres, in contrast to previous reports of high-elevation balance.” So, are we to believe that peripheral ice melt has any effect on the Greenland ice sheet and if so, what? Does an accelerating rate of loss presently 200-300 Gt per annum matter and if so why? -

MattJ asks: "It would have been real interesting to see how many of the deleted comments came from the 'skeptics'. Judging from the comment initially quoted above it sounds likely that most of them were, but the above statistics neither confirm nor deny that conclusion" The answer is as follows. The total number of visible deletions when the thread closed was 55. (Well-intented rebuttals to moderated posts are made to 'disappear' rather than be left as what we call 'tombstones' so as not to give the impression that the rebutter had also transgressed). Of that 55 posts, 44 were from deniers. The remaining 11 were all from warmists, including 3 from me and 1 from Dana. More telling perhaps is this: 44 denialist posts removed were written by 17 people, the remaining 11 were written by 6 warmists. -
Glenn Tamblyn at 17:54 PM on 30 January 2011Ten temperature records in a single graphic
Just to jump in here in defence of 'pirate' and the survey. It looks to me like several people here may have taken the wrong impression from what he said about the survey. My reading of what he said and the content of the survey is that this was a survey 'created by' his students, not just simply responded to by them. So yes, there are 'problems' with the survey. Qyestion 1 has 3 options for example without the obvious 4th option - 'all of the above'. But is this something foisted on the students, or a fault with what they produced? Perhaps pirate can clarify this. -

muoncounter at 13:35 PM on 30 January, 2011, whilst the study referenced, Yeh et al, may help better understand the shorter term events relevant to 2010, for 2010 itself to understood in a longer time frame, then perhaps it is the El-Nino/ La Nina occurrence ratio that must also be considered when new records are compared to past record events, and whether or not that ratio averages out, especially given the connection of the various record Brisbane floodings and La-Nina events. -
muoncounter at 13:35 PM on 30 January 20112010: A Year of Record Warmth and Weird Weather
#36: "it should be the nett effect of what occurred on BOTH sides of the system" Yes, I think that's an excellent point. Not only do oscillations average temporally to zero, but as you suggest, they average spatially to zero as well. That reinforces the point that these cyclic events can only be insignificant factors in the long term trend. The thread Global warming and the El Niño Southern Oscillation is an excellent place for discussion of this topic. To look at long term changes to the character of el Niño from its Eastern Pacific (EP) to Central Pacific (CP) phases, see Yeh et al 2009: Using calculations based on historical El Niño indices, we find that projections of anthropogenic climate change are associated with an increased frequency of the CP-El Niño compared to the EP-El Niño. When restricted to the six climate models with the best representation of the twentieth-century ratio of CP-El Niño to EP-El Niño, the occurrence ratio of CP-El Niño/EP-El Niño is projected to increase as much as five times under global warming. -- emphasis added Now that's a change that does not average out. -
johnd at 13:02 PM on 30 January 20112010: A Year of Record Warmth and Weird Weather
muoncounter at 10:18 AM on 30 January, 2011, whilst the article referenced from "The Australian" focuses in on how the events leading to the flooding developed in the more recent months, perhaps the stage was being set even further back, back during the preceding El-Nino which was identified by some as a variation of the normal El-Nino pattern, and labeled an El-Nino Modoki. A few accepted truths are perhaps relevant here, one being that a period of below average rain always ends with a period of above average rain. Another is that generally in Australia, by virtue of the regions it covers, there is nearly always a drought somewhere, even when there are may be floods elsewhere. One other is that what a La-Nina means to Australia, is what an El-Nino means to those on the other side of the system and vice versa, so when any analysis is being done on the effects on any such event, before it can be evaluated with reference to longer term climate trends, the bigger picture,it should be the nett effect of what occurred on BOTH sides of the system that are relevant rather than what may have been experienced on just one side. For me the big picture is not complete yet merely by looking at both sides of such events, but also looking at many such events over a longer time frame. With systems that operate in the various oceans and oscillate through identified positive and negative phases that perhaps seem to be 6 decades, more or less, then I am more interested in what can be observed over multiple such cycles, only then can any analysis have any real value above what essentially relies a lot on the making of assumptions and guess work. -

Stephen and Dana thanks for that, Stephen's link is a useful addition to the Real Climate account of the affair. I'm happy with all that - climate science should be left to climate scientists, or at least referred to them! The only, minor query I had is that the graph Real Climate shows in explanation begins in 1900. There is, if my ageing memory hasn't failed me, some additional warming before 1900 which would make the FEU "2.4 above" "pre-industrial", although still an exaggeration, slightly less of an exaggeration. Or have I misunderstood? -

Chemist1 @4, very nice of you to repeat the same error just to illustrate the point. However, it should be noted solar energy that drives weather is dissipated as heat. It is not removed from the system as you suggest, which would violate the conservation of energy. (It is also irrelevant to the question of thermal lag in the oceans.) Perhaps you should state your claim as "heat is transferred by weather" which is true, but also immediately seen as irrelevant. -

David #13 - the FEU-US error is discussed in the original Case Study article. Basically what they did was project the CO2-equivalent concentration (CO2 plus other greenhouse gases) in 2020, then using a climate sensitivity of 3°C for a doubling of CO2, estimated that the planet would be 2.4°C above pre-industrial temps. The problem is that the climate sensitivity parameter is an equilibrium value, and the planet is not in equilibrium (in short, FEU-US ignored thermal inertia). On top of that, they didn't take into account negative forcings like aerosols. -

michael sweet at 11:04 AM on 30 January 2011Latest GRACE data: record ice loss in 2010
The last line in the original post says Greenland lost about 200 Gton of water last year. That equals 200 km^3 of water. Wikipedia says the ocean surface area= 3.61x10^8 km^2. I calculate that as about 0.6 mm of sea level rise. This is too small to measure apart from the noise in sea level rise so far. Sea level rise is a critical factor to watch. It will probably (hopefully) be at least a decade before it becomes clear how much sea level rise is increasing. The sooner it is clear sea level rise is increasing the bigger the problem. Sqeptics say we don't need to worry since it is so small it will be 1000 years to rise a meter. Dr. Hansen describes how with the current doubling rates for ice loss (doubled since 2002 in Greenland as shown above) that could lead to 5 meters sea level rise by 2100. Dr. Hansen's estimate is the highest that I know of for scientists, but he has usually been right in the past. Other scientific estimates range from about 1-2 meters. The IPCC estimate is smaller but does not include Greenland and the Antarctic. Contrast that with Fydijkstra who asserts that there is no problem, cites a paper that documents record increasing ice melt in Greenland to support his denial of a problem, and has a funny graph with some missing data. Choose who you believe. -
From Peru at 10:38 AM on 30 January 2011Sea level rise is exaggerated
PDT: I have no idea why sea level rise does not show an acceleration as a consecuence of accelerating melt in Greenland and Antartica. However, the University of Colorado data seems odd to me, because (to the delight of the folks at WUWT) shows instead a deceleration of sea level rise. I suggest to follow the CSIRO and AVISO data and graphs: http://www.cmar.csiro.au/sealevel/sl_hist_last_15.html http://www.aviso.oceanobs.com/en/news/ocean-indicators/mean-sea-level/products-images/index.html That show a nearly constant trend of aproximately 3.2 mm/yr unlike the University of Colorado (U. of C.) that show a deceleration and a lower mean (linear) trend: 3 mm/yr, that seems to coincide with the AVISO trend when Glacial Isostatic Adjustement (GIA) is not applied, so I suspect that the U. of C. do not apply GIA in their product.

#34: "most major flooding events come about only after the ground reservoir has become fully saturated" That seems to be the case for the recent Queensland flooding. From The Australian: Super storm was brewing for a while "The thing which really stood out was the very regular falls of heavy rain in the southeast quarter of Queensland, with some areas recording their highest rainfall on record," says Karl Braganza, manager of climate monitoring at the National Climate Centre in Melbourne. That was before the arrival of cyclone Tasha -- another relatively weak storm, no doubt relatively low on the ACE scale, that was capable of substantial devastation. From the BOM Dec 2010 Queensland report: Many significant weather systems affected the state, bringing torrential rainfall at times, and severe thunderstorms battered the southeast coast between the 15th and 18th. A weak category one tropical cyclone, Tasha, crossed the coast south of Cairns early on Christmas morning and continuing active monsoonal activity led to a wet Christmas period that culminated in some of the most widespread and significant flooding in Queensland's history. "it most likely that it has been the preceding period where the determining factors are to be found." It seems that is correct. But what are the determining factors? From the same article in The Australian: Queensland climate services manager Jeff Sabburg says the high sea surface temperatures off the eastern Australian seaboard and northern Australia "produced record vapour pressure, which relates to how much moisture is in the atmosphere. There is extra moisture around and that translates obviously to a higher probability of rainfall." There's the same refrain: high temperatures (here, sea surface), higher probability of extreme weather events follow. -

Chemist1 @333 Also it is the.zeroeth law that desribes two bodies next to each other,at two different temps,and the resulting heat flow from a warmer to cooler body as well, in terms of equilibration. No, the zeroth law only establishes temperature as the property that is invariant when two systems are in thermal equilibrium, it says nothing about the direction of heat flow when they are not. This is covered by the 2nd law. -
Ron Crouch at 09:28 AM on 30 January 2011Follow-Up Case Study in Skepticism
All I can address David is the fact that the FEU neglected to take into account the negative forcings and the fact that there is some lag between the time CO2 is released and the full onset of effect as a result of that release. There are varying thoughts on that as well. The phasing out of coal as a home heating source can be seen in the temperature record, at least that's my perception. Some say 20 years, I say it's more like 30. But then some maintain that using wood for funeral pyres in Europe up until the 7th century is reflected in the temperature record as well. It is as I say, how you perceive things will greatly influence your perspective. And to gain perspective one needs to continue to learn on a daily basis with an unbiased eye, and an open mind. -
johnd at 09:16 AM on 30 January 20112010: A Year of Record Warmth and Weird Weather
Eric (skeptic) at 06:11 AM on 30 January, 2011, Eric, you are exactly right. These matters must be put into their true perspective by examining the bigger picture, not focusing narrowly on a single aspect. With rainfall, not necessarily referencing floods, whilst it is the most recent rains that can cause a situation to go from manageable to unmanageable, the seeds for such a transition have generally been sown much earlier. Perhaps it is easier for some to understand how it is the bigger picture that is most relevant by referring to drought. With drought, the severity is judged by the cumulative effects of extended periods of below average rain, cumulative being the operative word. Thus, the cumulative effects of two dry years preceded by two wet years is totally different than if they were preceded by two dry years. The ground reservoir is able to absorb and hold vast amounts of moisture and this is a relevant and important factor in both droughts and floods. Whilst flash flooding can occur before the soil is saturated, most major flooding events come about only after the ground reservoir has become fully saturated, as well as all the water courses, dams etc having neared their capacity to contain further inflows. Thus it does not necessarily take an extreme event to turn a situation from manageable to unmanageable, as you have shown. If such events are to be deemed to be once in 100 year events, then it is ridiculous to restrict evaluation to one or two days only when it most likely that it has been the preceding period where the determining factors are to be found. -

Ron at #6, that's my impression too. The whole thing strikes me again as being similar to the Himalayan glaciers, Amazon rainforests, flood prone land in Holland, "controversies". That is, what becomes discussed is the "error" in the exact timing or the exact extent, rather than the actual processes involved. With or without the errors, glaciers are still melting with future disastrous consequences for farming in Asia, the Amazon forests are still under obvious threat from climate change, Holland does face flooding as seas keep rising (as do other countries). Arguing about the detail of an error diverts attention from consequences, in this FEU case the effects on food production as the globe keeps warming. My impression Dana, Ron, was that the FEU error wasn't the result of some manipulation of data, or cherrypicking, but was at least in part the result of disagreement/confusion about the meaning of "pre-industrial" (as well as misunderstanding the thermal inertia question). Is that correct? -
Dikran Marsupial at 06:52 AM on 30 January 2011It's not us
Julian Flood@20 Are you questioning the attribution of the observed rise in atmospheric CO2 to anthropogenic emissions? If so, you don't need isotopic arguments to establish that the attribution is correct. The principle of conservation of mass requires that if both man and the natural environment are carbon sources (i.e. emissions exceed uptake) then the annual increase in atmospheric CO2 must be greater than anthropogenic emissions (our uptake is negligible), as it is the sum of the net anthropogenic and natural contributions. This is observed not to be the case, atmospheric CO2 is rising at a rate about 45% of anthropogenic emissions, so the natural environment must be a net sink, and hence is not causing the observed rise. That particular piece of attribution is rock solid. The fact that the long term rise in atmospheric CO2 has been steady at 45% of anthropogenic emissions would be abit of a coincidence if the observed rise were natural and nothing to do with us! -

I started a post on this thread that I never finished and I'm glad that I waited thanks to Michael. Aside from the clarification that Michael has attached to the data the fydijkstra supplied, I can see something totally different in the second graph that fydijkstra posted in #7. You see I perceive things differently, so I have different perspective, and obviously fydijkstra drew the downward slope because that is how he perceives things and thus it gives him a different perspective. I can filter out the slope that fydijkstra drew in the graph, and from my perspective I can imagine an upward sloping line that is on the order of 25-30 degrees starting from 1995 to the end of graph, because that's how I perceive things. So for me the issue becomes whether it's a simple case of difference of perspective, or whether fydijkstra is trying to deliberately deceive by manipulating the data to serve a biased perception. -

Tom Curtis #26, you said "In other words, the total amount of water involved was around twice as much as that which caused the 1974 floods". The report here http://www.bom.gov.au/climate/current/statements/scs24b.pdf says "Over the Brisbane River catchment as a whole, average three-day rainfall in the 1974 event was 348.5 mm, compared with 286.4 mm in 2011, and all four major sub-catchments were also wetter in 1974 than in 2011, although by small margins in the cases of the Bremer (1974 442.1 mm; 2011 417.1 mm) and Lockyer (1974 331.3 mm; 2011 292.0 mm) sub-catchments" But the sentence before says "The weeks prior to the 1974 event, whilst wetter than normal, were also less wet than the equivalent weeks prior to the 2011 event." Sounds to me like the water flowing down the rivers (twice as much as 1974) came from a less extreme event, but was preceded by a more protracted wet pattern starting before December. -
Mike G at 06:10 AM on 30 January 2011Monckton Myth #8: Rising sea levels
Cynicus @40 He said "Scleractinia"- the order of modern hard corals. Regardless, scleractinians probably DID evolve from actinians, which are the sea anemones, not sponges. But yes, the Permian was the only time when all known corals went extinct. However, there are other periods where corals nearly went extinct. The most notable of these events was from the Cretaceous to the Paleogene. During that period there are about 20 million years where there are no coral reefs and about 8 million or so where there are basically no coral fossils. Their diversity plummeted during that period and it now appears that the only species that survived were those that could do so without calcifying. It was those species that later re-radiated into the diversity of modern reef building corals. Corals very narrowly escaped extinction, but the other group of reef-builders at the time, rudist bivalves, did go completely extinct. -

Thank you for highlighting this difference between the camps. Hopefully it will help those who are inspired (unconsciously) by their desires to believe “anything but CO2” to recognize the difference between “skepticism” and “denialism”. -

Chemist1: Oh and a little information you may not know: you can ignore the thermal inertia of oceans in either calculation because a large amount of heat dissipates due to weather,thus not raising temps. Source, please? Unsubstantiated claims aren't valued very highly here. -

That's why I'm calling most of the "sceptics" Pseudo-Sceptics, as pseudo shows their attitude (pseudo-sceptic meaning: false, not genuine, fake sceptic) to scepticism as well as some of their tactics (Etymology, combining form of Ancient Greek "pseudēs": false, lying). It is a pity that many "positive" sounding terms describing the attitude towards AGW are conquered by the pseudo-sceptics: - (true) sceptic - climate-realists - true climate and so on. But words paint a picture in the minds of the listeners, so let's get rid of positive names for unlogic and unscientific behaviour. -

I think myself that in general the majority of people are too comfortable with accepting things at face value so long as it is in line with their thinking. There's not a whole lot of individuals who actually question the validity of a statement, even about subjects that they are familiar with. When I first saw an article on the FEU-US paper I thought it worthy of mention in another forum, but at the same time I knew there was something odd about it. I just had to sort it out. The first thing I did was to actually read the paper. After that I went to the AR4 to see what the scenarios predict. It didn't match. Then I went searching for contact information so I could query the author as to how they reached the conclusion that temperatures would rise by 2.4oC over the next 9 years. Well by the time I had it sorted out for myself, those who have a better line on contacts than me had already started to blog on the error. But because I had already read the paper I was focusing more on the FEU-US paper's other conclusions. And despite the fact that the world won't be 2.4oC warmer by 2020, that does not preclude that the rest of the conclusions may start to be witnessed in that 2020 time frame. I really don't think we need that much more of an increase in global average temperature before some of the effects discussed in the paper become visible markers. Of course I'm sure that the skeptics will read my comments here and I'll get branded a heretic as well. That's fine I have thick skin. But I guess what I am really trying to say to people in my post is to start using your critical thinking more often, even about issues you think you are familiar with, and do some research before you stick your foot in your mouth or shoot yourself in the foot. And as can be demonstrated in this forum and many others, get the proper perspective. I guarantee it will change your perception of the world around you. -

You mean most of the so-called skeptics are not really sceptics at all ? I am so surprised...not.
