I’m in San Francisco this week for the annual meeting of the American Geophysical Union (AGU), the world’s largest climate science conference. Over five thousand of the world’s top climate scientists are here, giving a staggering 10,000 talks and poster presentations. It’s total information overload, and I will only be able to offer this week but a small sampling of the incredible amount of science being presented here.

What is the coldest place in the world? It is a high ridge above 13,000 feet in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 135.8 degrees Fahrenheit (minus 92.2 degrees Celsius) on a clear winter night, announced polar scientist Ted Scambos of the National Snow and Ice Data Center, at a Monday press conference at the AGU conference. The official world cold record of minus 128.6 F (minus 89.2 C), set in 1983 at the Russian Vostok Research Station in East Antarctica will remain intact, though, since official records have to be measured by ground-based instruments. How cold is -135.8°F? That’s so cold that it would hurt to breathe, said Dr. Scambos in an AP interview. That’s also well below the -109°F temperature that dry ice (frozen carbon dioxide) begins to sublimate into gaseous carbon dioxide. But don’t get your hopes up that we can use the newly-found record cold spot to take CO2 out of the air and solve global warming—you need a temperature of -220°F (-140°C) to freeze CO2 out the air into dry ice “snow” at the concentrations that CO2 exists at in our atmosphere (about 398 ppm.) Still, it is an intriguing concept to build giant refrigerators in Antarctica to do just that—something that has been proposed by Purdue climate scientist Ernest Agee, in a research paper titled, CO2 Snow Deposition in Antarctica to Curtail Anthropogenic Global Warming, published earlier this year in the Journal of Applied Meteorology and Climatology .

Figure 2. In this spectacular photo from Antarctica taken by a NASA scientist on November 24, 2013, we see a lenticular cloud over a pressure ridge in the Antarctic sea ice. Lenticular clouds are a type of wave cloud. They usually form when a layer of air near the surface encounters a topographic barrier, gets pushed upward, and flows over it as a series of atmospheric gravity waves. Lenticular clouds form at the crest of the waves, where the air is coolest and water vapor is most likely to condense into cloud droplets. The bulging sea ice in the foreground is a pressure ridge, which formed when separate ice floes collided and piled up on each other. Image credit: NASA Earth Observatory.

Quoting 175. Gearsts:

The character of the 2013 season was unusual in that there were an average number of
tropical storms (13), but only two minimal (Cat. 1) short-lived hurricanes developed.
Previous research has taught us of the strong influence of multi-decadal variations of the
THC/AMO to the changing number and period of the most intense hurricanes. But we
had not analyzed in as much detail the influence of shorter period variations of the THC
and subtropical gyre on the influence on yearly hurricane changes.

Our large forecast error in 2013 was primarily due to a gross over-estimate of the number
and strength of major hurricanes. We were unprepared for the consequences of such an
unusual 2013 winter (Jan-Mar) to spring (April-June) decrease in the strength of the
THC/AMO and its associated increase in strength of the high pressure gyre. We estimate
THC strength from the proxy signals shown in Figure 6. Our older proxy used the SSTA
of the North Atlantic minus the SLPA of the Atlantic south of 50°N. A newer proxy for
the THC/AMO uses a combination of the SSTA, SLPA and the surface meridional wind
(V) in the eastern sub-tropical Atlantic.

The strength of the Atlantic high pressure gyre (or weakness in the THC/AMO) in the
spring period of April to June typically gives a good indication of the amount of intense
hurricane activity to follow later in the year.

It is very rare to observe such a large increase in the high pressure of the Atlantic gyre
between any winter to spring period as occurred in 2013. This large gyre increase was
the largest in our data sets. It is a rare ocean-atmosphere change event that was thus not
in our forecast developmental data set up to now – but will be included in future seasonal
forecasts.


It looks like they are convinced what caused the 2013 bust and will be incorporating it into future forecasts, so already the big bust has created new chances to increase forecast accuracy.

Well as its Tuesday night and there's is nothing better to write about. Here we go!

Quote from the blog heading:-

"Still, it is an intriguing concept to build giant refrigerators in Antarctica to do just that—something that has been proposed by Purdue climate scientist Ernest Agee, in a research paper titled, CO2 Snow Deposition in Antarctica to Curtail Anthropogenic Global Warming, published earlier this year in the Journal of Applied Meteorology and Climatology."

There was something about swallowing a spider to catch the fly!
Well first at minus 100/F or there about the construction of the giant refrigerator's is going to be a bit of a challenge, not to even think about how to power them on a good calm day!
Next, I'm sure some of the more learned members might have an idea of how many cubic kilometres or miles of CO2 is going to have to be stored against the end of civilisation as some of us have known it.
A few trillion tons either way will make little difference for the rough guide to how to save the planet from A Transient Humans point of view?
Then there is the problem of how many surplus army blankets or similar it will need to keep the darn stuff cold enough to stop it regaining its earlier place in the atmosphere?
Added to the equation we might include methane and anything else that fits the climate change bill, along with Chinese smog traps and a few radiation filters.
The list is endless, good job its late at night here in a rain starved, forgotten western fringe's of Europe.
PS think of all the CO2 that those delegates contributed to the atmosphere going to the conference!

Sounds like something you you would see in a "Day After Tomorrow" type movie as some last ditch effort plot line to save a city from a mega hurricane.

That's just silly nonsense, wind turbines can't "sap" energy from hurricanes. Sure they'll generate additional electrical power, but wind turbines will not create the necessary friction to slow the windspeed down, and they certainly won't weaken a hurricane. Maybe the idea should be turned into a movie script instead.




Not to mention they will get destroyed in stronger hurricanes, which the article writer even admits.
Enquiring Minds? Here ya go! "SAN FRANCISCO — Giant offshore wind farms could do more than provide electricity for major cities. They could suck the life and the power out of hurricanes barreling toward those cities, too, according to Stanford University research presented Monday at the American Geophysical Union fall meeting.

Stanford civil and environmental engineering professor Mark Z. Jacobson and his research team found that if it was feasible to build tens of thousands of wind power turbines off the shores of some of America’s cities most vulnerable to extreme weather, those cities would see lower wind speeds and less severe storm surges from approaching hurricanes.

The researchers imagined what would have happened if a massive wall of tens of thousands of wind turbines had been built before hurricanes Katrina and Sandy and ran computer simulations of both storms with and without offshore turbines constructed in their paths.

They concluced that the wind turbines could have sapped Katrina of so much energy that wind speeds would have been reduced by up to 50 percent at landfall and the hurricane's storm surge could have been reduced by about 72 percent, Jacobson said. It also would have generated 0.45 terawatts of wind power.

Hurricane Katrina, which devastated New Orleans and the Louisiana Gulf Coat in 2005, was the costliest and and one of the deadliest hurricanes to ever hit the U.S.

Jacobson's Katrina simulations assumed arrays of 70,000 turbines — 300 gigawatts of installed power — had been built 100 kilometers offshore southeast of New Orleans and were designed to withstand winds of up to 50 meters per second, just above the strength of a Category 3 hurricane, or roughly 111 mph.

The simulations showed that the turbines would create a net energy reduction in the atmosphere, slashing wind speeds as energy was sapped from the storm and dramatically reducing storm surge, which is caused by high winds pushing water inland as a hurricane barrels toward the coast.

Wind speeds would have been reduced enough to allow the wind turbines to survive the storm themselves, with winds never reaching 50 meters per second, above which the turbines could topple.

A similar array of wind turbines just offshore of New York and New Jersey could have reduced wind speeds of Hurricane Sandy by up to 29 meters per second, or 65 mph, with a storm surge reduction of about 21 percent, he said.

“If we have large arrays of offshore wind turbines — large walls of turbines — we could dissipate winds and storm surge quite a bit,” particularly in the vicinity of the turbines themselves, Jacobson said.

Jacobson did not address the feasibility or the political and environmental challenges of building such massive offshore wind farms along hurricane-prone coastlines. Proposals for smaller offshore wind farms have generated significant opposition and controversy, especially along Cape Cod in Massachusetts.

A study Jacobson co-authored in 2012 showed that offshore wind power can generate enough power to meet a third of U.S. energy needs.

“You’re generating electricity year-round, so (an array) would pay for itself,” he said Monday.

Jacobson said he has also envisioned constructing turbines worldwide to produce green energy that would meet half the world's energy needs. He said it would require 4 million wind turbines globally to do so.

"1.5 billion turbines would reduce wind speeds worldwide by 50 percent," Jacobson said.

Asked by an audience member how wind-farm construction on a such a large scale would affect local wind speeds and global weather patterns during normal conditions in the absence of hurricanes and other extreme weather, Jacobson said the large turbine arrays would likely reduce local shoreline wind speeds at most times, but would not likely affect global weather patterns overall, even if offshore wind farms were constructed on a global scale."

I believe you are correct.

To calculate 'average' temperatures and their anomalies, you have to know the daily low and high temperature.

Before the 80's I think there is not a systematic way of recording of worldwide daily temps. Only 'record' temps were documented, and not everywhere, as in if a record low or high was broken.

If anyone has more details on this and can site a source, please do! I have been wondering about this myself. I have looked and could not find the source for what I stated, though I believe I read it somewhere.


They update the 30-year norms every 10 years. The last time they were updated was in 2012. Before that they used a 1971-2000 base period. And before that 1961-1990 base period, 1951-1980 base period and so on.

Climate Science

The Battle Over Global Warming Is All in Your Head


Despite the fact that more people now acknowledge that climate change represents a significant threat to human well-being, this has yet to translate into any meaningful action. Psychologists may have an answer as to why this is

Today the scientific community is in almost total agreement that the earth’s climate is changing as a result of human activity, and that this represents a huge threat to the planet and to us. According to a Pew survey conducted in March, however, public opinion lags behind the scientific conclusion, with only 69% of those surveyed accepting the view that the earth is warming — and only 1 in 4 Americans see global warming as a major threat. Still, 69% is a solid majority, which begs the question, Why aren’t we doing anything about it?

This political inertia in the face of unprecedented threat is the most fundamental challenge to tackling climate change. Climate scientists and campaigners have long debated how to better communicate the message to nonexperts so that climate science can be translated into action. According to Christopher Rapley, professor of climate science at University College London, the usual tactic of climate experts to provide the public with information isn’t enough because “it does not address key underlying causes.” We are all bombarded with the evidence of climate change on an almost a daily basis, from new studies and data to direct experiences of freakish weather events like last year’s epic drought in the U.S. The information is almost unavoidable.

If it’s not a data deficit that’s preventing people from doing more on global warming, what is it? Blame our brains. Renee Lertzman, an applied researcher who focuses on the psychological dimensions of sustainability, explains that the kind of systemic threat that climate change poses to humans is “unique both psychologically and socially.” We face a minefield of mental barriers and issues that prevent us from confronting the threat.


(MORE: As Temperatures Rise, Empires Fall: Heat and Human Behavior)

For some, the answer lies in cognitive science. Daniel Gilbert, a professor of psychology at Harvard, has written about why our inability to deal with climate change is due in part to the way our mind is wired. Gilbert describes four key reasons ranging from the fact that global warming doesn’t take a human form — making it difficult for us to think of it as an enemy — to our brains’ failure to accurately perceive gradual change as opposed to rapid shifts. Climate change has occurred slowly enough for our minds to normalize it, which is precisely what makes it a deadly threat, as Gilbert writes, “because it fails to trip the brain’s alarm, leaving us soundly asleep in a burning bed.”

Robert Gifford, a professor of psychology and environmental studies at the University of Victoria in Canada, also picks up on the point about our brains’ difficulty in grasping climate change as a threat. Gifford refers to this and other psychological barriers to mitigating climate change as “dragons of inaction.” Since authoring a paper on the subject in 2011 in which he outlined seven main barriers, or dragons, he has found many more. “We’re up to around 30,” he notes. “Now it’s time to think about how we can slay these dragons.” Gifford lists factors such as limited cognition or ignorance of the problem, ideologies or worldviews that may prevent action, social comparisons with other people and perceived inequity (the “Why should we change if X corporation or Y country won’t?”) and the perceived risks of changing our behavior.

Gifford is reluctant to pick out one barrier as being more powerful or limiting than another. “If I had to name one, I would nominate the lack of perceived behavioral control; ‘I’m only one person, what can I do?’ is certainly a big one.” For many, the first challenge will be in recognizing which dragons they have to deal with before they can overcome them. “If you don’t know what your problem is, you don’t know what the solution is,” says Gifford.

Yet this approach can only work if people are prepared to acknowledge that they have a problem. But for those of us who understand that climate change is a problem yet make little effort to cut the number of overseas trips we make or the amount of meat we consume, neither apathy nor denial really explains the dissonance between our actions and beliefs. Lertzman has come to the conclusion that this is not because of apathy — a lack of feeling — but because of the simple fact that we care an overwhelming amount about both the planet and our way of life, and we find that conflict too painful to bear. Our apparent apathy is just a defense mechanism in the face of this psychic pain.

(MORE: The Evil Brain: What Lurks Inside a Killer’s Mind)

“We’re reluctant to come to terms with the fact that what we love and enjoy and what gives us a sense of who we are is also now bound up with the most unimaginable devastation,” says Lertzman. “When we don’t process the pain of that, that’s when we get stuck and can’t move forward.” Lertzman refers to this inability to mourn as “environmental melancholia,” and points to South Africa’s postapartheid Truth and Reconciliation Commission as an example of how to effectively deal with this collective pain. “I’m not saying there should be one for climate or carbon, but there’s a lot to be said for providing a means for people to talk together about climate change, to make it socially acceptable to talk about it.”

Rosemary Randall, a trained psychotherapist, has organized something close to this. She runs the U.K.-based Carbon Conversations, a program that brings people together to talk in a group setting about ways of halving their personal carbon footprint. Writing in Aeon, an online magazine, Randall suggests that climate change is such a disturbing subject, that “like death, it can raise fears and anxieties that people feel have no place in polite conversation.” Randall acknowledges that while psychology and psychoanalysis aren’t the sole solutions to tackling climate change, “they do offer an important way of thinking about the problem.”

Lertzman says the mainstream climate-change community has been slow to register the value of psychology and social analysis in addressing global warming. “I think there’s a spark of some interest, but also a wariness of what this means, what it might look like,” she notes. Gifford says otherwise, however, explaining that he has never collaborated with other disciplines as much as he does now. “I may be a little biased because I’m invested in working in it, but in my view, climate change, and not mental health, is the biggest psychological problem we face today because it affects 100% of the global population.”

Despite the pain, shame, difficulty and minefield of other psychological barriers that we face in fully addressing climate change, both Lertzman and Gifford are still upbeat about our ability to face up to the challenge. “It’s patronizing to say that climate change is too big or abstract an issue for people to deal with,” says Lertzman. “There can’t be something about the human mind that stops us grappling with these issues given that so many people already are — maybe that’s what we should be focusing on instead.”

Tropical Cyclone Advisory #34
SEVERE CYCLONIC STORM MADI (BOB08-2013)
20:30 PM IST December 10 2013
=======================================

At 15:00 PM UTC, the severe cyclonic storm MADI over west central Bay of Bengal moved southwestward during the past 3 hours and now lays center near 15.0N 84.8E, about 420 km east southeast of Machillipatnam, 530 km northeast of Chennai and 810 km north northeast of Trincomalee (Sri Lanka).

It would move southwestwards and weaken gradually.

According to satellite imagery, the Dvorak intensity of the system is T3.5. The associated convection depth and intensity has decreased during past six hours. Convection is being sheared from the low level circulation center. Associated broken low/medium clouds embedded with intense to very intense convection is seen over the area between 15.0N to 20.0N and between 82.0E to 88.0E. The lowest cloud top temperature is about -60C.

3 minute sustained winds near the center is 55 knots with gusts of 65 knots. The state of the sea is very high around the center of the system. The central pressure of the severe cyclonic storm is 990 hPa.

Forecast and Intensity
=======================
9 HRS 14.4N 84.0E - 50-55 knots (Severe Cyclonic Storm)
21 HRS 13.4N 83.0E - 35-40 knots (Cyclonic Storm)
45 HRS 11.5N 81.0E - 30 knots (Deep Depression)

Wasn't suggesting global is cooling. I do remember that record that was found by satellite as well. To be honest, it's less of surprise they found a hotter area than colder area of the planet. I'm sure a record 160 F or more will be broken in near future.


That would have to be a satellite measurement. "Most humans will suffer hyperthermia after 10 minutes in extremely humid, 140-degree-Fahrenheit (60-degrees-Celsius) heat."

We'll it is Dr. Masters' blog, so he talks about what he wants I'd imagine. In active hurricane seasons, you'll probably note the vast majority of his topics are related to tropical cyclones as that's our focus on here during the summer.

Actually, this isn't even really about global warming, it's about a record low temperature. The last few blog posts have also been about current weather stories, such as snowstorms in the US, severe storms in Europe, etc.
One post asking about GW makes it "all" about GW...

Maybe I'm crazy but I am much more afraid of mile high ice sheets advancing on NYC that I am a few meters rise in sea levels.


You might also think about the fact that the last glacial ice sheet to cover North America took about 10,000 to 20,000 years to form and reach its southern limit. How many of us will still be around in 10,000 years, assuming the ice sheet has begun to build in Northern Canada (where the snow and permafrost are melting more each year)?

Why do Global Temperature Anomalies Maps only go back to a 1981 - 2010 baseline?

Was 1981 when satellites started ploting Global Temperatures?


I believe you are correct.

To calculate 'average' temperatures and their anomalies, you have to know the daily low and high temperature.

Before the 80's I think there is not a systematic way of recording of worldwide daily temps. Only 'record' temps were documented, and not everywhere, as in if a record low or high was broken.

If anyone has more details on this and can site a source, please do! I have been wondering about this myself. I have looked and could not find the source for what I stated, though I believe I read it somewhere.

Kids, don't try this at Home!


Eh...I got into a little snafu with a wall once back in third grade. I won the battle.

I must say though, I was very happy that Mom allowed me to sleep in, we got off of school today for the stuff that fell last night. Apparently, even if we were in school, I wouldn't have made it; an 18-wheeler jack-knifed in the construction zone of the busiest section of I-65 in Nashville...right where I go and about the same time as when I go through, too.

I have gotten about 11" total already. That is tied with the total from all of last year. And it is only December 10th. I am happy :)

I got three inches at my house,so that brings this year snow total at my house to 6 inches for the winter so far (3 inches from Sunday and 3 inches from today).Not bad..not bad..
Correct me if I am wrong but isn't that just as much if not more snow than you got in 2011-12, 2012-13 winter combined?

Hey, maybe you'll see my presentation there. :D

Actually a co-worker will be doing the presentation since I'll be too busy to attend myself.


Your coworker is going there?
I might be going to watch them.

Yes that was quite a nice trick to blame Global Warming for a cooling Earth.


Care to cite your source for that? No research papers I'm aware of make any such claim.

I was very impressed they pulled it off even without the requisite Gulf Steam shutdown. I thought the argument that AGW could in fact lead to greater snow falls had some merit but I never did nor do follow the argument that AGW leads to a cooler Earth since the warmth is now trapped at some mysterious place deep in our oceans. Still scratching my head over that one.


This is probably because you don't have a an in depth understanding of physical oceanography. There's nothing mysterious or puzzling going on here. The oceans have currents. Some are fast, some take decades to cycle, some even longer.

Heat doesn't just suddenly spring into existence and then just vanish. When you add heat on a consistent basis to a large heat sink like an ocean, then the average temperature will increase. And since the ocean is a fluid that heat gets transported in all three dimensions depending on winds, geography, salinity, etc.

Maybe I'm crazy but I am much more afraid of mile high ice sheets advancing on NYC that I am a few meters rise in sea levels.


That's because you're not thinking things through. It wouldn't take much of a climate shift to turn the agricultural centers of the world into deserts. A couple degrees of additional warmth will allow non-native species to migrate northward, potentially wrecking havoc (like the bark beetle is doing in Colorado). Along with these species will come tropical diseases. Even a meter of sea level rise would end up causing problems for coastal areas, especially in storm surge type situations. And that's just a few possible consequences.

You're fear of ice sheets is illogical given the real, measured, changes happening to our planet NOW from warming. There is absolutely zero evidence of climatological cooling.

this is the 12z CMC at 90 hours





That is a little better..at least it shows some parts of NC getting something. Doesn't help you and I here on the coast though lol...oh well...just gotta keep reminding myself it is not until Jan and Feb for our best chances here on the coast.
