Eric, the significance of Grinsted, is that other measures of whether storm-intensity correlated with warmer temperatures are plagued by observational bias. Grinsted's tidal gauge method would indicate the temperature does indeed load the dice. -

Dale, I am an Australian too and I have been fighting global warming ignorance amongst my countrymen for years – with some success. We may call a spade a spade but our character has nothing to do with scientific reality. Your character is misplaced in this case. -

Dale, if you want to "call climate science out", then it is incumbent on you to at least demonstrate that you actually know what climate science actually says. So how about answering the question? -

vrooomie @ 79: I find it funny how you believe WUWT to be my "home turf". I'm Australian, my "home turf" (if you want to call it that) is Jo Nova. ;) WUWT, like SkS, is a minor interest site to me, not a daily visit. michael @ 75: I was not being deliberately offensive. I was calling climate science out. All we hear is "this may happen in this range". It's all probabilities on assumptions on how things may work in a hypothetical world. Science is fact, not mumbo-jumbo. Sorry if that offends you, probably the Australian way of calling a spade a spade coming out in me. -

It seems that we can all see what we want as the truth when we don't want to see the actual truth. If somone doesn't want to see the truth then nothing anyone else says will make them see it, for the only way to see the truth is to look, and firstly to want to look, without any self orientated motivations or preconceptions. However giving the false truths credence in agruement lets them spread to a wider audience and thus challenging every denial claim (when most are clearly irrational now) just gives them unwanted air time, unwarranted credence, creates unecessary doubt and is distracting away from the real issues as is the intent of those in denial. At present there is already a real and very alarming change in the weather arround the world, (everywhere extremes are already the norms) and this is just the start, just the start! Therefore maybe instead of trying to convince someone in denial of their denial state of mind, to get them out of it somehow (which is an impossible task), we should be discussing more urgent things? Like how on earth is NYC going to adapt its infra-strcutre for future norms and extremes, sea level rise and water security whilst also not having the luxury of any fossil fuels? For the truth of the current situation is that burning any more fossil fuels than essential for adaptation and transformation is really just too dangerous. -

Re: "pure" O2 in an engine, I'll stand by my statement: There is *NO* internal combustion engine that will run on pure O2, nor benefit appreciably by the use of O2. I agree. It would take a new design, not a jury rig. Check patents 8176884, 7543577, and others. The original post pointed out POSIBILITIES because of a NEW efficient, economical way to produce pure O2 and allow carbon capture. All present methods to produce O2 are about 14% efficient compared to the theoretical energy it should require (exergy). This means it takes about 8 times the energy and lots of equipment. Coal power plants, fuel cells, industrial furnaces, and cars and everything else, are designed to operate in our 21% O2 atmosphere. What would they look like on a planet that had a 100% O2 atmosphere? -

Alpinist@77: Even Dale's home turf, WUWT, isn't exactly safe for a rational person to point out what you've pointed out, in your last sentence. Even there, it's considered in pretty bad taste to minimize a storm that has, to date, killed over 50 people, and looks like it will easily top the damage from a "real" hurricane, Isaac. They're eating their own. -

Climate Central has had some excellent coverage of the build up, the arrival and the linkages of the storm to Global Warming. Also the Jeff Masters wunderground blog. It's really none of my business, as I am not a US citizen, but I think that those of you who do not wholly support Governor Romney's programme should be thanking Dale and his ilk, and encouraging him to continue posting these comments as much as possible and as widely as possible for the coming 5 days. -

Dale: I'd recommend you have a look at Jeff Maser's Wunderblog regarding Sandy. Jeff has a very detailed history there and determined very early that Sandy had no escape route and could be extremely damaging. Jeff also has an excellent discussion of the Greenland blocking ridge and its effect and potential relationship to the loss of Arctic sea ice. As for your initial comment downplaying the severity of Sandy...this is probably the wrong site for that sort of comment as you've figured out by now... -

New Research for the topic: Evidence of recent causal decoupling between solar radiation and global temperature "We have shown that there is an evident causal decoupling between total solar irradiance and global temperature in recent periods. Our work permits us to fix the 1960s as the time of the loss of importance of solar influence on temperature. At the same time greenhouse gases total radiative forcing has shown a strong Granger causal link with temperature since the 1940s up to the present day. ..."

wili at 06:14 AM on 1 November 2012New research from last week 43/2012
Last full abstract posted-- "Increasing seabed temperatures make gas hydrate unstable in shallow Norwegian-Svalbard margin regions Ocean temperature variability for the past 60 years on the Norwegian-Svalbard margin influences gas hydrate stability on human time scales" --seems pretty darn important to me. It seems to contradict what Archer and others have been saying--that these hydrates would take a very long time to destabilize, so they don't pose an immediate risk. Also, if the methane can be released faster than it breaks down into CO2, we could see significant (perhaps catastrophic?) increases in atmospheric methane from this source. (I'm hoping that someone will show me how I am--or this article is--wrong. 'Cause if I'm right, we are in a world of even deeper hurt than most imagine.) -

I thought only deniers cherry-picked? @Dikran: I've learnt over the last few years to take the IPCC reports with a pinch of salt. It's been years since AR4 and a lot of research has shown the IPCC not correct on a number of things. Recent research into cyclones shows no trend change in major storm activity. Individual basins change, but globally there's none. Yet you want me to take the word of a single paper over the many. (-snip-) (-snip-).

wili at 05:34 AM on 1 November 2012The View from Germany: Tackling the real questions
Don't believe every Fox (aka Faux) News blurb you read or hear. "Opponents of renewables in North America are pouncing on the news of a new coal plant in Germany, especially because German Environmental Minister Peter Altmaier cut the ribbon, so to speak. Altmaier said Germany will need the conventional fossil power plants for "decades to come," though he did not say it was, as Fox Business put it, to "complement unreliable and intermittent renewable energies such as wind and solar power." In fact, he stated that "fossil energy and renewables should not be played as cards against each other" and that we have to move beyond "making enemies of the two." It took six years to build the plant, meaning that the process started in 2006. It is by no means a reaction to the nuclear phaseout of 2011. And as Altmaier himself points out, the new plant can ramp up and down by 150 megawatts within five minutes and by 500 megawatts within 15, making it a flexible complement to intermittant renewables. In the area, 12 coal plants more than 40 years old have been decommissioned, and the new 2,200 megawatt plant is to directly replace 16 older 150 megawatts blocks by the end of this year, so 2,200 megawatts of new, more flexible, somewhat cleaner capacity (the new plant has an efficiency of 43 percent, whereas 35 percent would be considered ambitious for most old coal plants) is directly replacing 2,400 old megawatts. Germany has a target of 35 percent renewable power by 2020, rising to 85 percent by 2050 – meaning that 65 percent of its power supply will be conventional in 2020, and the country will still have 15 percent conventional power by mid-century. Obviously, Germany needs to build some new conventional power plants to reach even that ambitious goal for renewables." http://www.renewablesinternational.net/is-germany-switching-to-coal/150/537/56081/ -
Chris G at 05:32 AM on 1 November 2012The View from Germany: Tackling the real questions
I'd be pleased if there were more general acknowledgement in the U.S. that a problem exists; dealing with reality in other words. It's hard to have a discussion about how best to handle a problem if half the people won't acknowledge that a problem exists. I wonder if part of the problem is that nothing really bad has happened to the U.S. for too many generations for the general populace to realise that bad things can happen. Universally, no one wants to believe that bad things will happen to them as individuals; and if the cultural memory of past events has grown dim, maybe there is a cultural reluctance to believe what is happening. I mean, for example, WWII was not a good time for anyone, but the U.S. never experienced substantial bombing or foreign troops on its soil, and a lot of countries did. Most of our wars that anyone can remember have been fought on television in some remote place. You have to go back to the 1930s to find large impacts felt at home, and there isn't much living memory of that time. -

Good point, adelady. As usual, $$$ is likely to be the only reality that significantly changes habits and habitats. IIRC, last week SwissRe increased it's rates for insurance companies doing business in North America because the rate of pay outs for disasters was going up so quickly. They also made it very clear that the kinds of disasters that were increasing so dramatically were specifically weather, heat and drought--the ones most closely linked to GW. -

The media speculation about how long it will take for subway service to resume in the flooded tunnel sections are laughable. Salt water and electrical equipment are incompatible. The entire train detection system, signal system, Automatic Train Stop system, switch motor control system and all switch motors in the flooded tunnels will need to be completely replaced, not to mention any substations and main bus junctions for the power third rail. In short, we're talking months before through service can resume in the tunnels that were flooded. When was the last time that happened again, Dale? -

Dale wrote "if this system had've hit a much less populated area, and much less financially and politically important area, would the same media hype have been seen?" That's an interesting statement, really. It could be analyzed at many levels, but let's just consider the physical one. The storm's diameter was about a thousand miles. Where in the US could such a storm hit and not affect any major financial and political center? Forget the West coast. At that kind of dimension it could affect all of California, or everything From Seattle on South. In the South? All of the Golf's oil production, shipping and refinery, everything on the Texas coast, all the way to Florida. Let's hypothesize a storm centered smack on the four corners: it still would have affected Denver, Salt Lake City, Oklahoma City, Dallas/Fort-Worth, Phoenix, etc, etc. It's becoming awefully hard for populated areas to hide away from storms these days... Of course, one could argue that, when such storm piles heaps of bodies somewhere in Central America, the US media barely budges. Just goes to show that the message has to be hammered home to the reality impervious types. Yet, even at that, they still try to wiggle out of the obvious. -
jyushchyshyn at 04:14 AM on 1 November 2012The View from Germany: Tackling the real questions
If Germany were serious about tackling global warming, it would phase out coal rather than nuclear power. Suppose that renewable energy sources could supply all of our energy needs in 50 years. If we phase out coal and continue to use nuclear power we could stop using coal in 25 years. If we phase out nuclear power and continue to use coal, we will be puting carbon dioxide into the atmosphere for all 50 years. Until renewable power can supply all of our energy needs, the choice is not between nuclear power and renewable power. Why not use both? The choice is between nuclear power and coal. -
Doug Bostrom at 03:47 AM on 1 November 20122012 SkS News Bulletin #1: Hurricane Sandy & Climate Change
Further to KR's point and distilling to the essential: it's all about energy. Global warming is about retained energy and energy can't be hidden. Expecting atmospheric phenomena to behave identically as they did before despite now being driven by more energy is just silly. Teasing out the precise differences in behavior of given weather phenomena as available energy changes is not easy but the absence of perfect description doesn't mean energy has disappeared or somehow can't manifest itself until it's been reduced to equations. -

To clarify my comment: 1) I was talking about current food prices that are up and are going to continue to rise, given the bad wheat crop after the bad corn crop, and then the inevitable rise in meat prices that is going to follow this winter (and hasn't hit yet). 2) I was also talking about food prices going up and staying up, above and beyond what the recent drought has brought (given that such droughts will be more frequent and just as bad, and will pile onto the previous droughts). 3) I was also, mostly, talking about the geopolitical ramifications that such changes would have in the developing world, again something we are not actually seeing at the moment (except for the possible causative influence on the Arab Spring), but we will... and that may be one of the scariest implications of all. Imagine riots, rebellions, wars and chaos, rivaling Somalia of the 1990s, but striking across the globe in Africa, the Middle East, Asia, and even perhaps weaker developed countries (Greece comes to mind, and maybe Italy, given their position, similar to Texas and Oklahoma, at the edge of the northern Hadley Cell, subjecting them to both their own droughts combined with their own debt crisis). -

2012 SkS News Bulletin #1: Hurricane Sandy & Climate Change
Dale - "Sandy wasn't even a category 1 when it made landfall. ...Katrina and Yasi sized cyclones/hurricanes eat Sandy size storms for breakfast and don't even flinch. Sandy wasn't even a small hurricane. It was a big storm, that is all." It has been noted elsewhere, however, that:In terms of sheer kinetic energy -- a measure of the windspeed integrated over how wide an area the winds are blowing -- the super-storm also shattered records going back to at least 1969, said [Jeff] Masters, a former "hurricane hunter" with the National Oceanic and Atmospheric Administration, in a phone call with The Huffington Post Tuesday morning. "That includes Katrina, Andrew, Wilma -- all the Category 5 storms -- Sandy had them beat," Masters said. "If you take the size of it -- it was so vast and it had winds blowing over such a wide area of ocean -- it put a tremendous volume of ocean water in motion and carried it with it as it moved northwards. And guess what? When that water hit land, it had nowhere to go but on the land and generate a record storm surge."
(Emphasis added) Dale, this "wasn't even a category 1" storm may have done somewhat less damage than the category 5 Katrina - we'll have to see what the costs add up to. It wouldn't have been anywhere nearly as powerful or damaging without the anomalously warm offshore waters feeding it energy, or the off-track jet stream. Both of which are factors known to be affected by global warming, I'll point out. Details matter, Dale. Your dismissal of storm Sandy seems to miss a few. -

My "Frankenstorm(s) moment arrived in the 'noughties,' notably in 2006/07 when Denver had ~7~, count'em, *seven* blizzards in a row (one/week, all on weekends!!). Born and raised here, I had NEVER seen so much snow. I was snowed in for days, diggin' like a mad man to get out (..to get to work: I said I was mad!!). There were drifts around town exceeding 8 feet in depth, and in areas where the snow had lain down flat, some exceeded 4 feet deep. We had an April blizzard this year--not terribly unusual for here, save for the fact of its intensity and depth of accumulation--and with the focus on the *intensity* of these winter storms and fire events, I've prepared accordingly. I'm sure are all aware of our not-quite-past yet fire season which was terrible, here and all over the West: Along with that, and a number of other weather extremes, all since 2001, have made me aware of the patterns changing, and in my mind, it's beginning to approach what I can see as serious climate change. -

ACE uses storm velocity--essentially a measure of max sustained wind. It does not incorporate storm size/structure. The ACE for Sandy will show it to be a hurricane of weak to average strength--with most of the strength coming from its duration. ACE will not account for strength across volume. There have been other measures proposed, of course, and better instrumentation will allow even more measures to be developed. See Powell & Reinhold (2007) on the subject. -

“The terrifying truth is that America faces a future full of Frankenstorms,” said Shaye Wolf, Ph.D., the Center’s climate science director. “Climate change raises sea levels and supersizes storms. The threat of killer winds and crushing storm surges will grow by the year unless we get serious about tackling greenhouse gas pollution.” Here’s how scientists say climate change feeds the superstorm triple whammy: 1. Global warming loads storms with more energy and more rainfall. 2. Storm surge rides on higher sea levels, so more coastline floods during storms. 3. Melting sea ice and accelerating Arctic warming are causing changes in the jet stream that are bringing more extreme weather to the United States.

Can't help but compare Dale's speculative fiction with what the real, non-fiction NYC mayor is confronting. Bloomberg:You did not have ocean water, salt water, breaching the banks the way you’ve had it in Manhattan, you know, in my lifetime….. When you start to fill the subway tunnels with salt water—much of the Con Ed equipment is in the tunnels, is underground—when hot electrical equipment hits cold salt water, that is a bad combination. And that is a design flaw, I believe, for our system now, if you anticipate these extreme weather conditions. Obviously we didn’t when we designed this system. We did not anticipate water coming over the Hudson River, coming over the banks, being five feet deep on the West Side Highway, and filling subway grates and every opening and filling that massive infrastructure we have below ground. Going forward, I think we do have to anticipate these extreme types of weather patterns. And we have to start to think about how do we redesign the system so this doesn’t happen again. After what happened, what has been happening in the last few years, I don’t think anyone can sit back anymore and say “Well, I’m shocked at that weather pattern.” There is no weather pattern that can shock me at this point. And I think that has to be our attitude. And how do we redesign our system and our infrastructure assuming that?”
The Mayor of New York City understands the concept of longitudinal change, a good thing because what Bloomberg sees and understands today will shape the lives of future New Yorkers for better or worse. Bloomberg's job is in part to create a better New York in days to come. If he chose to pretend nothing unusual happened in the past few days he would miss the opportunity to have a positive benefit on the New York of tomorrow. Why people like Dale are so invested in throwing sand in the wheels of progress is deeply mysterious. -
M Tucker at 02:26 AM on 1 November 20122012 SkS News Bulletin #1: Hurricane Sandy & Climate Change
Albatross, @49, I think we should also add the influence of changes to the NAO caused by the unprecedented melting of the Arctic during the summer months. "Here’s where climate change comes in. The atmospheric pattern that sent the Jet Stream south is colloquially known as a “blocking high”—a big pressure center stuck over the very northern Atlantic Ocean and southern Arctic Ocean. And what led to that? A climate phenomenon called the North Atlantic Oscillation (NAO)—essentially, the state of atmospheric pressure in that region. This state can be positive or negative, and it had changed from positive to negative two weeks before Sandy arrived. The climate kicker? Recent research by Charles Greene at Cornell University and other climate scientists has shown that as more Arctic sea ice melts in the summer—because of global warming—the NAO is more likely to be negative during the autumn and winter. A negative NAO makes the Jet Stream more likely to move in a big, wavy pattern across the U.S., Canada and the Atlantic, causing the kind of big southward dip that occurred during Sandy." "The arctic climate system is changing so dynamically that the rules of the game are changing," Greene says. "This is not the same Arctic Ocean we've known. The Arctic and North Atlantic oscillations are changing in ways we hadn't anticipated." The interplay, which has always been fairly consistent, he says, has now become "a wild card" affecting our weather." (from a couple of articles on the Scientific American web site) Favorite denialist tactics: downplay every extreme weather event and the relentless summer Arctic melting. -

Son of Krypton at 01:58 AM on 1 November 20122012 SkS News Bulletin #1: Hurricane Sandy & Climate Change
Dale - But I don't apologise for sounding "sceptical" of the climate change claims affecting Sandy While it's impossible to say for certain, there is the distinct possibility that global warming-caused decline in sea ice contributed the course Sandy took. Taken from a presentation from Dr. Jennifer Francis: Arctic sea ice loss may significantly affect the upper-level atmospheric circulation, slowing its winds and increasing its tendency to make contorted high-amplitude loops. High-amplitude loops in the upper level wind pattern (and associated jet stream) increases the probability of persistent weather patterns in the Northern Hemisphere, potentially leading to extreme weather [Source] This wavy, blocking pattern is exactly what we expect from decreased sea ice, so it’s very possible that this block may have been boosted in intensity and/or duration by the record-breaking ice loss this summer. Further, as Master's pointed out, the waters off the Northeast coast are a full 5°F above average, adding to the amount of energy and water vapour available. You also brought up the devestation caused by Katrina; yet look at the factors that contributed to the real extent: Failing levies, in some cases due to a lack of upkeep Sections of New Orleans are below sea level, a result of the Mississippi not being able to replenish sediment for a few hundred years, needed to counteract subsidence.

Given that I'm completely clueless about this ACE stuff, could you elaborate upon your assertion? Asking as a skeptical..scientist, natch! If (when) the denialati are going to come after "us" with the alleged nonsense, I'd like to be schooled in why it *is* nonsense. -

Climate scientists warn that global warming is likely to increase the incidence of serious events like Hurricane Sandy. Warming water and rising sea levels may be contributing to what New York politicians are calling their 'new reality.' For details see: Did global warming cause superstorm Sandy?

Dale on the '38 storm: 14-25 foot storm surge (also during a full moon) which if occurred today has been estimated would cause $40 billion in damage to New York. NOAA:Storm surges of 10 to 12 ft inundated portions of the coast from Long Island and Connecticut eastward to southeastern Massachusetts, with the most notable surges in Narragansett Bay and Buzzards Bay. Heavy rains before and during the hurricane produced river flooding, most notably along the Connecticut River.
Even if Dale is truly desperate to sway opinions it's still better to stick to an accepted standard of facts. Otherwise we're likely to forever hear about the famous '38 storm and its ever-growing surge, always bigger than the biggest surge yet. -

I ran across this comment, by Bernard J, from a few months back: it bears repeating in this thread. "On the matter of denialism itsef, as embodied by Minchin, Palmer and so many others, it's like this... ...There's a corspe, formerly known as Ms Ecosystem, lying on the ground, and the corpse has a CO2 bullet in its head - a bullet fired at point-blank range from a Coalington-Oilchester rifle. There's a medico autopsying the corpse, a Dr Climatologist, and she concludes that the cause of death was an AGW brain injury resulting from the impact of the dissected CO2 bullet, now lying in the bloody kidney bowl. Watching the autopsy is a member of the NRA, a Mr W.A.S.P. Warming-Denier Snr, who (although he has no experience in medicine) variously asserts that: 1) there is still a scientific debate about the capacity of CO2 bullets to inflict serious damage to brains 2) well, OK, bullets might cause small bumps, but something else caused the corpse to actually die even though the autopsy showed no other plausible factors 3) that the corpse isn't really dead anyway 4) that CO2 bullets are good for the brain 5) alright, so maybe the bullet did kill Ms AGW, but if you control firearms, my life will fall apart, it just will. Nothing that Mr W.A.S.P. Warming-Denier Snr asserts has any objective relationship to the science that determined the cause of death. Several are ideological knee-jerks in response to the implications of the investigation, but these knee-jerks do not alter the fact of cause and effect. The debate isn't about the cause of death, no matter how strenuously Mr W.A.S.P. Warming-Denier Snr attempts to make it so. The debate is simply about Mr W.A.S.P. Warming-Denier Snr's unfettered ability to continue to do what he's always done, no matter that control of this activity would result in less harm in the future. If Mr W.A.S.P. Warming-Denier Snr wanted a genuinely honest discussion, he'd openly admit that CO2 bullets will kill most, if not all, of Ms AGW's family if they are all thusly shot, and he would argue that his right to shoot those CO2 bullets at these folk outweighs the rights of Ms AGW's family not to be shot at. Of course, that is a much harder argument to win, so Mr W.A.S.P. Warming-Denier Snr is going to avoid it at all costs, even if he can never admit it even to himself..." Indeed.Moderator Response: [Sph] Sorry, vrooomie. That was a bit too loud, I think. I toned it down (one strong tag, not two).
