Massive volcanic eruptions caused Little Ice Age, froze the Thames

A mysterious, centuries-long cool spell, dubbed the Little Ice Age, appears to have been caused by a series of volcanic eruptions and sustained by sea ice, a new study indicates.

The research, which looked at chemical clues preserved in Arctic vegetation as well as other data, also pinpointed the start of the Little Ice Age to the end of the 13th century.

During the cool spell, which lasted into the late 19th century, advancing glaciers destroyed northern European towns and froze the Thames River in London and canals in the Netherlands, places that are now ice-free. There is also evidence it affected other continents.

"This is the first time anyone has clearly identified the specific onset of the cold times marking the start of the Little Ice Age," said Gifford Miller, a geological sciences professor at the University of Colorado, Boulder, and the lead study researcher. "We also have provided an understandable climate feedback system that explains how this cold period could be sustained for a long period of time."

The cause appears to have been massive tropical volcanic eruptions, which spewed tiny particles called aerosols into the atmosphere. While suspended in the air, the aerosols reflect solar radiation back into space, cooling the planet below.

The cooling was sustained after the aerosols had left the atmosphere by a sea-ice feedback in the North Atlantic Ocean, the researchers believe. Expanding sea ice would have melted into the North Atlantic Ocean, interfering with the normal mixing between surface and deeper waters. This meant the water flowing back to the Arctic was colder, helping to sustain large areas of sea ice, which, in turn, reflect sunlight back into the atmosphere. The result was a self-sustaining feedback loop.

Miller and colleagues came to these conclusions by looking at radiocarbon dates — based on how much of the radioactive form of carbon they contain — from dead plants revealed by melting ice on Baffin Island, in the Canadian Arctic. Their analysis found that many plants at both high and low altitudes died between A.D. 1275 and A.D. 1300 — evidence that Baffin Island froze over suddenly. Many plants also appeared to have died at around A.D. 1450, an indication of a second major cooling.

These periods coincide with two of the most volcanically active half centuries in the past millennium, according to the researchers.

They also found that the annual layers in sediment cores from a glacial lake linked with an ice cap in Iceland suddenly became thicker, indicating increased erosion caused by the expansion of the ice cap in the late 13th century and in the 15th century .

"This gave us a great deal more confidence that there was a major perturbation to the Northern Hemisphere climate near the end of the 13th century," Miller said.

Simulations using a climate model showed that several large, closely spaced eruptions could have cooled the Northern Hemisphere enough to spark sea-ice growth and the subsequent feedback loop.

It's unlikely decreased solar radiation, a separate theory to explain the Little Ice Age, played a role, according to the researchers.

The research will appear Tuesday (Jan. 31) in the journal Geophysical Research Letters.

    • Prophets, of many religions actually, have told us to watch for significant changes to the norm. What we are watching today qualifies as a significant new set of climate variables. Not to mention the southern hemisphere that's supposed to be experiencing summer is having significantly reduced temperatures in places also.

      Cold, cold, cold weather is being experienced to the west (Alaska) and to the east (Europe). It doesn't take a rocket scientist then to conclude something is in the pipeline for the eastern United States.

      Something on the order of a Biblical scale.

      I believe strongly in observing ALL VARIABLES not just charts from past ages. One of the variables being brushed aside, which to me is a mistake, is the prophecy found at Matthew 24, Luke 21 and Mark 13. Those are parallel accounts that have a few variations [put there not by mistake but to give people today the full picture taken together].

      According to those prophetic writings a Great Calm is to come immediately before the conclusion of this "system of things" not the destruction of the entire planet. When people observe this period of Calm they are supposed to heed Jesus' warning to "get out of Jerusalem". Jerusalem there does not stand for the city of Jerusalem it stands more for a condition in the world, a condition of the world being stuffed to the gills with false religion.

      So what's a "false religion". The vast majority of religions today claim there's NO SUCH THING. Jesus stated the road leading to perdition is Wide and Spacious but the road leading to life is to be Narrow & Cramped, few finding it. In short, he was saying a small religious group would be the one having Bible Truth.

      All of which means the churches all claiming different from what Jesus said claiming that all religions are OK with God, they are the ones who constitute the worldwide permeation of Society called False Religion. In agreement with that we come to Revelation, the last book of the Bible, Chapter 18 which says GET OUT OF HER MY PEOPLE.

      Which reverse engineered is telling us if you want to be called "MY PEOPLE" you have to flee out of all false religions DOING SO WITH THE UTMOST URGENCY (mash the gas pedal & burn rubber). Sitting around blogging, arguing over CO2 concentrations with a person you know will always disagree, does not achieve the objective. All it does is run out the clock.

      The only religion on Earth that understands the Book of Revelation is Jehovah's Witnesses. All the other religions say Revelation is a "MYSTERY" to evade the fact that God is not giving them the required information? Not exactly. Many of them actually know, having read our books explaining it in detail. BUT THEY DON'T TELL ANY OF THEIR PARISHIONERS BECAUSE THEY LIKE THE MONEY.

      However, let it be said also that the final understandings of Revelation have not reached print. There has been a revealing of much, much more than what is in our book. We have experienced Lift-Off that has raised us high above every other religion on Earth. God's holy spirit is a very powerful rocket fuel that only Jehovah's Witnesses are given. Like Jacob in the Bible we were given all of the Blessing, and the collective Esau has lost it.

      Warming Brings Severe Winters

      Most extreme winter Arctic atmospheric circulation on record; "Snowmageddon" results

      The atmospheric circulation in the Arctic took on its most extreme configuration in 145 years of record keeping during the winter of 2009 - 2010. The Arctic is normally dominated by low pressure in winter, and a "Polar Vortex" of counter-clockwise circulating winds develops surrounding the North Pole. However, during the winter of 2009 - 2010, high pressure replaced low pressure over the Arctic, and the Polar Vortex weakened and even reversed at times, with a clockwise flow of air replacing the usual counter-clockwise flow of air. This unusual flow pattern allowed cold air to spill southwards and be replaced by warm air moving poleward. Like leaving the refrigerator door ajar, the Arctic "refrigerator" warmed, and cold Arctic air spilled out into "living room" where people live. A natural climate pattern called the North Atlantic Oscillation (NAO), and its close cousin, the Arctic Oscillation (AO) were responsible. Both of these patterns experienced their strongest-on-record negative phase, when measured as the pressure difference between the Icelandic Low and Azores High.

      The extreme Arctic circulation caused a bizarre upside-down winter over North America--Canada had its warmest and driest winter on record, forcing snow to be trucked in for the Winter Olympics in Vancouver, but the U.S. had its coldest winter in 25 years. A series of remarkable snow storms pounded the Eastern U.S., with the "Snowmageddon" blizzard dumping more than two feet of snow on Baltimore and Philadelphia. Western Europe also experienced unusually cold and snowy conditions, with the UK recording its 8th coldest January. A highly extreme negative phase of the NAO and AO returned again during November 2010, and lasted into January 2011. Exceptionally cold and snowy conditions hit much of Western Europe and the Eastern U.S. again in the winter of 2010 - 2011. During these two extreme winters, New York City recorded three of its top-ten snowstorms since 1869, and Philadelphia recorded four of its top-ten snowstorms since 1884. During December 2010, the extreme Arctic circulation over Greenland created the strongest ridge of high pressure ever recorded at middle levels of the atmosphere, anywhere on the globe (since accurate records began in 1948.) New research suggests that major losses of Arctic sea ice could cause the Arctic circulation to behave so strangely, but this work is still speculative.

      Quoting from the much debunked, alarmist skepticalscience blog does nothing to forward your argument.

      "...for the Winter Olympics in Vancouver, but the U.S. had its coldest winter in 25 years. "
      I thought this was about warming, or did the warming cause the cooling?

      You forget the basic thing here, the planet is not warming, hasn't been for fifteen years, and the planet did not begin it's life in 1948, so prove this weather (because that's what you're talking about here, not climate) didn't happen before 1948.

      Also, "Like leaving the refrigerator door ajar, the Arctic "refrigerator" warmed" sorry, already debunked so many times.

      I'm sorry but I'm bored with this nonsense.
      Good try, but not good enough - Try again.

      "I thought this was about warming, or did the warming cause the cooling?"

      It's always been about climate extremes -- more severe droughts, floods, tornadoes, downpours, hurricanes, typhoons, heatwaves and blizzards-- all of which have been dramatically increasing during the past few decades just as predicted by climate scientists 50 years ago.

The days of lone men walking the streets with "the end is nigh" banners is long gone, he has been replaced by the extremists who tell us the planet is broken, we did it - it's all our fault, and if we don't tax CO2 - the end is nigh!!!

      I wrote to your leader (JfG) some time ago telling her that she could be useful in some circles, but due to her extremist and totalitarian views she is virtually useless in the real world. No-one in authority would ever take her seriously - believe me, I know!
      Same goes for you, to a degree, though I respect the fact that you do seem to have a slightly more measured response to the debate, even though your 'science' is gleaned from known alarmists' blogs and you're easily sucked in by propaganda. And there's the problem. You have the intelligence to think for yourself yet you take what is often the most ridiculous crap and accept it without thinking.
      If you thought about things for a while you might start to see things differently. Read a wider range of literature and then think about it, don't just take what the 'experts' say as gospel, I don't. And if you think my information comes only from one 'side' you'd be totally wrong.

    • Thanks to my very good friend Coolplanet, without whom I would never have seen this tweet, for supplying me with this excellent opportunity to show just a tiny snippet of stories from the past few days of this "Year without a winter"... you really have to laugh... a lot! But wait, who will be the first to tell us all this weather is being caused by CO2?

      BELGRADE, Serbia: "The situation is dramatic, the snow is up to five metres high in some areas, you can only see rooftops," said Dr. Milorad Dramacanin, who participated in the helicopter evacuations.

      Europe: The death toll from a severe cold spell in Eastern Europe rose
      to 71 Wednesday, most of them homeless people.

      Turkey: Heavy snowfall paralyzed daily life in Turkey, especially in Istanbul, yesterday as the country’s biggest city experienced its coldest day in the last 33 years.

      UK: Professor Dame Sally Davies, the Department of Health’s Chief Medical Officer and Chief Scientific Adviser, said: “Mortality rises by 19% in winter months in England, amounting to 27,000 excess deaths or 1,560 more people per week.

      Ukraine: KYIV — Forty three have died of hypothermia in the Ukraine over the past six days as the country has suffered a severe spell of cold weather, the emergency services ministry said Wednesday.

      Alaska: For example in Circle Hot Springs, AK on Sunday, 29 Jan 2012 the HIGH temperature was a blistering -49°F, breaking the -44°F record which has stood since 1917. It gets better.
      That same day in Circle Hot Springs the low temperature was -58°F breaking the old record of -52°F set in 1941 by six degrees.
      ...Question: If the all-time temperature record nearly broken for the entire country were a warm record, would NBC News, ABC News, CBS News, and CNN have produced segments on this latest proof of global warming? You know the answer to that question.

      France: The huge Paradiski ski domain in the French Alps which combines Les Arcs, Peisey Vallandry and La Plagne with 425km of piste says snow levels in parts of its vast domain are the deepest they have been at this time of year for 46 years.

      Japan: Heavy snow has left 53 dead and hundreds injured in several prefectures in western and northern Japan, it has been learned.

      Bulgaria: Bulgaria faced another day of record low temperatures on January 31 2012, with a "Code Orange" weather warning in force for the whole country and with the severe weather having claimed two lives the previous day.

      Serbia: Some municipalities in Serbia are cut off and unreachable due to the bitter cold, with temperatures in some areas dropping below minus 20 degrees Celsius, and the cold has claimed its first victims.

      I'm fully aware that some parts of the Northern Hemisphere are experiencing extreme cold and snow. It's called Climate Change which brings weather extremes all around the planet.
      But this article is about what caused the Little Ice Age. It was SO2 aerosols in the atmosphere from volcanoes, NOT changes in the Sun as deniers have long claimed.
      This new study shows that small changes in Earth's atmosphere cause huge swings in temperatures globally. Too much SO2 and it gets dramatically colder. Too much CO2 and it gets dramatically hotter.
      This has been accepted scientific fact for over 100 years. It's called the Greenhouse Effect.

      I'm learning from you (thank you ever so much) that our entire climate/weather system is, and always has been, driven by SO2 and CO2. Now, if only we could convince everyone else of that, especially those nasty deniers!!!

      If volcanoes did cause the Little Ice Age, and I'm not saying volcanoes didn't have an influence, it is plausible, that means it was warmer before that period and after. Does that mean reduced volcanic activity has caused the warming?
      Was that period the only period of volcanic activity?
      Why does that period coincide with a period of low sunspot numbers?
      Does a period of low sunspot numbers cause volcanic activity?

      Why did the BBC, usually first to promote man-made global warming, add this:
      "“Analysis of the later phase of the Little Ice Age also suggests that changes in the Sun’s output, particularly in the ultraviolet part of the spectrum, would also have contributed cooling.”"

      So the sun's output is a factor at times (and we know this) but not at other times?

      So many questions. I'll leave it there, I don't want to give you too much to ignore.

      Sulfur dioxide and carbon dioxide are not the only drivers of climate. Methane and water vapor play a big role, as well as numerous other gasses, like hydrogen sulfide.

      The greenhouse effect isn't just "a nice blanket of gases that keep us warm." It can also send us into an ice age according to the theory.

      It doesn't even keep us warm, it regulates the temperature and that includes keeping us cool.
      Water vapour is by far the most influential player in the atmosphere effect (it doesn't even resemble a greenhouse) and CO2, apart from the first few ppm, plays a very small part and is not responsible for the warming we saw in the last century.

      First off, sunspots do not cause volcanoes or global warming, period. This has been very well established by science.

      Yes, long term variations in solar output do play a part in warming or cooling. But the key factor in climate change are levels of greenhouse gasses in the atmosphere which was proven in the 19th Century and is undisputed by peer-reviewed Science to this day.

      The oceans and polar ice also play a huge role which occur after atmospheric levels of greenhouse gasses rise or fall. Ice cores (etc) going back millions of years clearly show this: the higher the CO2 the hotter the climate and the lower the CO2 the colder the climate.

      This is very clearcut and should be easy to understand, if not for endless stupid questions.

      Water vapor IS a greenhouse gas!
      H2O is perhaps the most important greenhouse gas of all, as it constitutes the hydrological cycle that traps tropospheric heat through evaporation. The hotter it gets from CO2 the more H2O in the air which downpours and blizzards, and is one reason we are seeing such severe floods and snowfalls in the past decades.
      For Christ sake man EDUCATE yourself on this subject before spouting off your mouth!

      scientific process = Scientists create scientific theories with the scientific method, when they are originally proposed as hypotheses and tested for accuracy through observations and experiments.[2] Once a hypothesis is verified, it becomes a theory.

      I read further down on this post....has anyone explained or asked this IDIOT.....WHERE IS THE ICE CAP????? His assumption that in the course of the Earth's history 4 billion years.....in the last 30 years it just so happened to be NATURAL.... it just happens?????

      The problem is IceKat represents the intelligence quotient of most AGW deniers and seems to know more about this subject than most people. This is a problem!
      I have actually found debating IceKat mind-expanding as I not only get to see into the mind of the denier but it challenges me to further research and explain climate science so the average person can more easily understand. This is not an easy task as even climatologists admit they have failed to communicate the importance of global warming to people.
      IceKat has helped me articulate how very straightforward it really is.
      I'm so glad people like you are reading these exchanges because there is some good information coming out of it (and a lot of hours going into it).

      Okay, I understand your beliefs in the "Greenhouse" effect is still stuck in the 19th century so I won't take that any further here. Most of us have moved on, and although the majority of scientists of all descriptions still use the term "greenhouse effect" most people have now understood this to be quite a misleading statement. Our atmosphere does not act like a greenhouse, or anything like one.
      Our atmosphere regulates the temperature of the planet.
      There is a lot of new research that shows clouds and solar variations have an effect on climate. Now I know you're going to go rushing for your latest Romm blog, or get skepticalscience to debunk what I have just written. The fact is you will be able to find a lot of 'peer-reviewed' literature to debunk the theory of solar/cosmic ray and cloud effects on climate. That's fine, though, these things take time to be accepted, especially as a lot of people (scientists and governments) would have to do a lot of back-tracking before openly stating that they got it wrong and CO2 is no longer a problem. It will happen, though, and you will see it. In many circles there is already a lot of talk about failed science, and red faces abound!
      I tell you something - when real life does not follow theory, it's time to change the theory.

      "...the higher the CO2 the hotter the climate and the lower the CO2 the colder the climate."
      CO2 rises after temperature. This is well known. CO2 does not cause the temperature to rise, if it did, why, with ever increasing concentrations of CO2, has the UK's Met Office had to concede the fact that there has been no warming for fifteen years?
      During the last century there was a twenty year period when CO2 concentrations and temperature seemed to be in tandem, twenty years only.
      Why did the earth start warming before CO2 concentrations were significant enough to cause the warming?
      What caused the Medieval warm period? Was there too much CO2 then?
      What caused the Roman warm period? Too much CO2?
      During those periods the planet did not burn to a cinder, life did not end, and the planet cooled afterwards. Why are you so sure the planet won't cool again? Hint; it is ;)

      "H2O is perhaps the most important greenhouse gas of all"
      Which is why I wrote, "Water vapour is by far the most influential player in the atmosphere effect.". You call it a greenhouse, which it isn't, I call it an atmosphere, which it is.

      "The hotter it gets from CO2 the more H2O in the air which downpours and blizzards."

      What about when it gets hot from other sources than CO2?
      What about the other warm periods long before CO2 could have been the cause?
      Read about the atmosphere and you'll learn a lot, but you first need to get away from your obsession that CO2 is the cause of warming or you're going to look even more stupid in the near future.
      Personally, I can't wait to see how you're going to get out of the CO2 hole you've been digging yourself into.

      "...and is one reason we are seeing such severe floods and snowfalls in the past decades."
      So how do you explain the severe weather events documented in the past? For every one of your modern-day disasters, there is an equal amount of severe weather to be found in the past, a lot of it much worse than what we sometimes see today.
      Multi-agency reports have already shown conclusively that the weather is not getting more severe, weather events are not becoming more frequent, and even the likes of NASA and the UK's Met Office already concluded that events such as the Russian heatwave, the heatwave in Europe, Texas last year, and floods and droughts are nothing at all to do with the so-called man-made climate change.

      For Christ sake little girl EDUCATE yourself on this subject before spouting off your mouth!

      Strange, isn't it, how I can post a few comments here; one detailing severe winter events happening now, even though Michale Mann calls this a "year without a winter" and then I post numerous charts showing current temperature anomalies, each one showing how much colder than average the northern hemisphere (and parts of the southern hemisphere) currently is.
      In a nutshell, you have a climate 'scientist' telling us there is no winter, yet I manage to show current data and real-life commentary that disputes Mann's assertion... and you call me an idiot?

      "WHERE IS THE ICE CAP????? "
      You tell me? Has it all gone yet?

      As for "...checking sources, using facts, and know of the scientific process." believe me, I spend most of my life doing just that, and have done for many decades. You see, that's why I post current real-world data here as opposed to relying on the latest prediction from climate models, and interpretations from failed graduates who write scare-stories and then disappear without trace when their predictions fail miserably.

      How about trying to write something sensible, eh? And you don't need to write using capitals, I'm sure not even your 10 year old niece does that.

      The problem is you keep avoiding questions.

      If the temperature began to rise before CO2 could have had an influence, why do you blame CO2 for the warming? Also please explain previous warm periods and why the earth didn't fry during those times.

      Were temperatures around the Little Ice Age the correct temperatures for the planet? You seem to think it's too hot now, so would you like to see a return to a colder climate?

      Why has there been no warming for fifteen years while CO2 concentrations continue to rise? Is CO2 broken?

      Why do you call me a denier? What am I denying, that the climate changes? I've always agreed the climate does change, always has done, always will. Do I deny that the planet warmed? Absolutely not, it did, or rather the temperature fluctuated both upwards and downwards, and is now on a downward trend.

      Yes, volcanic eruptions cool the earth. Take for instance the largest eruption I know of, Tambora volcano in Indonesia. It blew in April 1815 and there was no summer because the ash obscured the sun causing the largest famine of the 19th century and reportedly killing 100,000 people. Now if volcanoes cause global warming this eruption would have fried much of the planet. In present day human CO2 emissions out pace volcanic http://news.discovery.com/earth/volcanoes-co2-people-emissions-climate-110627.ht.... There is no disputing the effect of natural cycles especially when pushed to the brink by other forcings, which we see happening right now particularly with our glaciers and oceans.

      U.S. Seems To Have Largely Escaped Winter

      A combination of factors has trapped winter's cold air over Canada and Alaska, making for unseasonably warm weather in the Lower 48.

      Throughout the continental United States, it's been a very warm winter.

      "The talk across the whole country has been, 'Where has winter been?'" said Dale Eck, who runs the global forecast center at the Weather Channel in Atlanta.

      The answer: A combination of factors has trapped the winter's cold air in the northern latitudes over Canada and Alaska.

      "If you look at U.S. temperatures, you'd say, 'Wow, it was a warm winter,'" said Dan Cayan, a climate researcher at the U.S. Geological Service and the Scripps Institution of Oceanography in La Jolla. And you'd be right.

      Scolnik explains:
      "This is now the 13th consecutive month that new high temperature records have exceeded low temperature records in the U.S., since cold records eked out a ratio of 1.5 to 1 vs. heat records in December 2010. The preliminary reports from the National Climatic Data Center through January 30 show heat records crushing cold records by a ratio of 20.7 to 1, nearly as high as the incredible 22.2 to 1 last August. Without the 25% of total January cold records set in Alaska, the ratio for the contiguous 48 states is 27.5 to 1. With meteorological winter now two-thirds over, the ratio for the season as a whole is at 6.2 to 1."

      Actually, yes, a volcano did go off somewhere, in Alaska. I don't know the name of it but yesterday the News said it was dormant til just recently. I'm sure you can find it faster than me... but the dust eruptions from it could be drifting over to Europe.

      Yes, I know but doesn't it seem strange how so many places, even in the southern hemisphere where it is summer, with the exception of North America are having so much cold weather? Maybe it's all down to CO2? Couldn't be anything to do with the planet cooling down, could it?

      A warm winter? Surely that's great for those who like to be warm? Can you use this winter as a prediction? One eminent scientist said in 2000, "children just aren't going to know what snow is anymore" and then feet of the stuff fell from the skies. Now, you might like to tell us global warming will cause more snow, and find a quote from Mann, Hansen or even the one who seems to be emerging with god-like status here, Romm to show unequivocally that global warming does indeed cause snow, but I'm afraid you'd be quite wrong. The most welcome period of natural global warming we experienced last century (it ended before 1998) has come to an end. Your planet is not enduring any form of global warming now, and even when it did, it started long before CO2 could have been an influence.

      Alaska Dispatch:

      "According to the Alaska Volcano Observatory, the aviation color color code and the alert level of Cleveland Volcano was upgraded on Tuesday to "Orange" and "Watch" to reflect new satellite data indicating increased activity.

      The east central Aleutian Chain volcano, which sits 45 miles west of the community of Nikolski, has spent much of the past year teasing that it would erupt, and its status has alternated between "Yellow/Advisory" and the more serious "Orange/Watch" four times since July 2011.

      The AVO reports that the lava dome that had developed at Cleveland last year was mostly removed by a brief explosive episode at the end of December. But new satellite images indicate that a fresh lava dome, approximately 130 feet in diameter, has formed in the summit crater.

      There have been no explosions or ash emissions detected during the current lava eruption, but the AVO notes that it remains possible for intermittent, sudden explosions of blocks and ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop."
      http://www.alaskadispatch.com/article/cleveland-volcano-alerts-upgraded-renewed-...

      Not much activity here yet, therefore this volcano couldn't be responsible for the frigid temperatures seen over the majority of the northern hemisphere over the past few weeks.

      Here's a prediction for you; at some point you're going to be telling us the climate is broken and man caused global cooling through man's production of CO2 causing global warming, that's after it caused the cool period around the 70s and the warmer than now period around the 30s. Keep moving the goal-posts, that's the way :)

      Being an avid skier myself I'm well aware of the situation at the ski resorts and the lack of early snow in parts of north America was evident. But why did you cherry-pick that article?
      Does it represent the entire planet, or even the majority?
      Could you not have shown us news reports of snowfalls way above average throughout Europe, Asia, and even Greece and Turkey?
      Why did you conveniently leave out well below average temperatures for the vast majority of the northern hemisphere, and some places in the southern hemisphere?

      But let's not get too caught up in the past weather in Colorado. The future's bright...

      "KUSA - A potent winter storm coming on shore in the Pacific Northwest Wednesday morning will bring big changes to Colorado's weather Thursday and Friday. Wind, snow and a big temperature drop are all headed this way.
      A powerful cold front is scheduled to arrive in northwest Colorado Wednesday night, bringing snow to parts of our northern and central mountains. "

      It’s Cold In Alaska, So Sarah Palin Asks: ‘What Global Warming?’ | In a post on her Facebook page, former Alaska governor and former GOP vice-presidential candidate Sarah Palin noted that Alaska school children don’t get out of school until temperatures drop below -55 degrees fahrenheit. Putting up a photo of her son doing chores in -20 degree weather, Palin asks: “Global warming? What global warming?” Palin notes “the balmy 65 degree (above zero) weather in the Beltway today” — a record high. Nonetheless, Palin is making the common mistake of confusing weather with climate change. She might not notice it, but the pattern of warming is clear. Even the U.S.’s northernmost city — in Alaska — felt the effects last year with “a record-breaking 86 consecutive days at or above freezing, far more than the previous record of 68 days set in 2009.” (HT: Blake Hounshell)

      You have missed the entire point of this article. Deniers have used the Little Ice Age to claim climate change is controlled by the Sun. This new finding shows that it is controlled by gasses in the atmosphere. Too much SO2 and it gets colder. Too much CO2 and it gets hotter.

      Well as you can see here, the real MO to bring the conversation back to cold not meaning the Earth isn't warming as a whole is the same bs and not even worth a response. The changing weather patterns we are seeing globally as a trend are part of climate change. Agriculture and plant life as it is being affected, part of climate change. The rate of acidification of the oceans, part of climate change. These are events that have set trends to them and the nuances that show there is more to the effects they are now bringing than natural variation and they are affecting real people and other species. I'm personally keeping my eye on that big freshwater bulge in the Arctic to see what comes of it. Distractions only seek to take your eye off what is truly important, and it isn't whether some avid skier can go slooshing off a slope and claim that global warming has been vanquished because of it. Typical mumbo jumbo from the usual players who truly haven't a clue to what this is all about and how ecology and biodiversity as well are being affected by all of this.

      "...the same bs and not even worth a response." But you couldn't stop yourself anyway. Hi Jan, lovely to hear from you again. So, whenever we have record low temperatures and snowfall over a wide area, to you it's irrelevant and says nothing. Yet a hot day anywhere in the world is conclusive proof of man-made global warming. Just wait until the summer when you drag out the most obscure record from some city to prove that the planet is, in fact, cooking to a cinder. Come on, even the UK's met office, a world leader in extremism, is having to backtrack and admit there's been no warming for fifteen years. Sorry chick your theory is dead in the water, has been for well over a decade.

      "I'm personally keeping my eye on that big freshwater bulge in the Arctic."

      Sure you are, because it's about all you've got to keep your eye on at the moment, not that you understand it of course!
      Have you any data from, say, the Medieval warm period to say this sort of thing is unusual now? Or from the 1930s when it was warmer than today? Or from the Roman warm period? Do you have any facts to back up any theory you may have without relying on the failed models?

      Of course there are big changes in the weather, when haven't there been changes?
      Climate changes all the time, always has done, and will continue to do so long after you're pushing up daisies!

      So, it is a cold winter in the northern hemisphere. Where's CO2 now then? is it all hanging out in the US, just waiting to be released to some other part of the world that needs a climate disaster?

      I hear you here and tend to agree.
      But this hot/cold debate gives us the perfect oppotunity to explain the greenhouse effect and global warming to most people who haven't the first clue about climate science.
      Perhaps that is IceKat's role here -- to challenge us to intelligently respond and learn something in the process.
      I find it crucially important to understand what causes glacial and interglacial ages in order to be able to communicate the dynamics of climate change. It all depends on the amount of greenhouse gasses in the atmosphere as this latest study reaffirms.
      Basically scientists are finding that it all depends on the concentration of warming CO2 and cooling SO2 aerosols in the air (plus the Milankovic orbital cycle of 41,000 years).
      It is a heated debate among paleoclimatologists whether global warming is preventing us from entering another ice age which we are overdue for according to the Milankovic theory.
      This is the crux of this entire dispute.
      Personally I would much prefer another ice age over another Eocene hellhole which we are creating with our greenhouse gasses. Life in the oceans thrive during ice ages which are the predominent climate state over the past billion years.

      Sorry, you're quite correct, and maybe it was silly of me to post data showing short-term predictions!
      I have to agree, it is far better to believe the predictions of extremists, such as predictions of doom and gloom in centuries to come, rather than take notice of NCEP data which predicted the temperature anomalies shown in the charts above. Maybe if you dig deep enough you'll find some link from NCEP to Big Oil; maybe one of these guys drives a big car, or maybe someone there doesn't recycle?
      However, if you care to look a little further than your back yard you'll see that these predictions are pretty damn accurate, unless you care to deny the fact that the vast majority of the northern hemisphere is currently undergoing a severe frigid spell and many places are experiencing temperatures well below average. So much for the climate alarmist Michael Mann's rant about a "year without a winter".

      Obviously you're choosy about what data you believe, so maybe you'll believe a photo of the recent snow in Athens, Greece.

      That being said, take a closer look pleez. From Canada down through Pennsylvania, Virginia and Georgia there seems to be warmer temperatures. It's everybody else to the east and to the west getting plastered with killer cold, tornadoes and snows.

      A prophecy foretold this would happen. Climate Peace in a small area that includes where the Watchtower Society of PENNSYLVANIA was first incorporated. The WTS is the legal for Jehovah's Witnesses. A line of angelic protection has been established that will grow to include the world, when the time comes.

      Soon. For now you get to look at it => Much like how Pharaoh and his charioteers stood and watched the pillar of fire then the cloud keep them from chasing the Israelites into the water to drown. It's all going down again and all your charts hahaha do nothing. Your positive feedback posts, also nothing.
