Global warming? No, actually we're cooling, claim scientists
Source: The Telegraph
A cold Arctic summer has led to a record increase in the ice cap, leading experts to predict a period of global cooling.
There has been a 60 per cent increase in the amount of ocean covered with ice compared to this time last year, they equivalent of almost a million square miles.
A leaked report to the UN Intergovernmental Panel on Climate Change (IPCC) seen by the Mail on Sunday, has led some scientists to claim that the world is heading for a period of cooling that will not end until the middle of this century.
Professor Anastasios Tsonis, of the University of Wisconsin, said: 'We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped.

OneCrazyDiamond
(2,031 posts)the cooling is not predicted in almost all of the models, and the ones that do, do not reflect it to the observed degree.
It gives steam to the counter argument, real or not.
Igel
(35,300 posts)More CO2 is being sequestered in the deep ocean--that the boundary between the cold, deep ocean and the middle regions that atmospheric CO2 gets into isn't as impermeable as thought.
Problem: Even if increased deep ocean CO2 has been observed, and even if isotope analysis of the deep water CO2 shows it's recently moved from the atmosphere, atmospheric concentration of CO2 has, in fact, continued to build up, so even if it's being sequestered there should still be some increases in T over the last dozen years on average. But it's flatlined. It's only "increased" because they've increased the window for calculating the moving average. Early GW deniers used the same trick to try to make the upward trendline for global warming go away. (It's known as principled hypocrisy--the principle being that the data has to be made to say what you think it should when public policy decisions are on the line and you think you're right.)
Another option: That ENSO just happens to be trending cooler than it had been.
Problem: The anti-AGW folk retorted that global warming was just ENSO trending towards having warm water surface off the western South Am coast--and that that's precisely how global warming gets implemented.
That the data are wrong. 'Nuff said on that point.
That the Arctic Oscillation happens to be trending more often to the east than it had been. But it had trended west before that, and helped boost temperatures. The Arctic Oscillation is a fairly newfangled discovery, so we don't have much of an observational history for it.
And the winning answer, until there's a need for a better one: That the Arctic is the Arctic, and it's only one subset of the data.
The runner up: Global warming is still complex, the models not as complex, and if there's a hiccup that we haven't figured out it's a chance to have our models trashed and do some new science. Or it's just a random event. Shit happens--it's why there's a 95% or a 99% confidence interval, and not a 99.99999999% confidence interval.

and of course, we don't call it "most ice extent in the Arctic warming" but rather "global" warming of which the arctic is but a small part of
there are also other things to consider, like the thickness of that ice.
Arctic sea ice cover naturally grows during the dark Arctic winters and retreats when the sun re-appears in the spring. But the sea ice minimum summertime extent, which is normally reached in September, has been decreasing over the last three decades as Arctic ocean and air temperatures have increased. This year's minimum extent is approximately half the size of the average extent from 1979 to 2000. This year's minimum extent also marks the first time Arctic sea ice has dipped below 4 million square kilometers.http://www.nasa.gov/topics/earth/features/2012-seaicemin.html
"Climate models have predicted a retreat of the Arctic sea ice; but the actual retreat has proven to be much more rapid than the predictions," said Claire Parkinson, a climate scientist at NASA Goddard Space Flight Center, Greenbelt, Md. "There continues to be considerable inter-annual variability in the sea ice cover, but the long-term retreat is quite apparent."
The thickness of the ice cover is also in decline.
It's good to see flat earther stuff posted here though
DeltaLitProf
(769 posts). . . could it also be wrong on its face? Could it be wrong even about the square mile coverage of the ice?
stupidicus
(2,570 posts)the volume would be hard to calculate (but that's why thickness is important) and it's doubtful the coverage numbers are wrong.
It's the "cooling" conclusion that is more than suspect because this one episode simply doesn't support it. This is like saying that since 1999 wasn't as hot as 1998 in terms of land temps, ergo we've entered a time of global cooling. One year does not a trend make.

The seasonal decline of extent through the month of August was slightly above average at 56,400 square kilometers (21,800 square miles) per day, but more than a third slower than the record decline rate in August 2012. This years August extent was the sixth lowest in the 1979 to 2013 satellite record.
August 2013 ice extent was 2.38 million square kilometers (919,000 square miles) above the record low August extent in 2012. The monthly trend is 10.6% per decade relative to the 1981 to 2010 average

Climate change is a far better term as it can be used to describe any unusual weather event such as a colder than usual winter or an extremely warm summer. A rash of tornadoes or a hurricane season with a large number of strong hurricanes can be attributed to climate change.
History proves that our climate is always changing. At one time the Sahara Desert was a great place to live.
Sahara Desert Was Once Lush and Populated
Bjorn Carey | July 20, 2006 10:07am ET
At the end of the last Ice Age, the Sahara Desert was just as dry and uninviting as it is today. But sandwiched between two periods of extreme dryness were a few millennia of plentiful rainfall and lush vegetation.
During these few thousand years, prehistoric humans left the congested Nile Valley and established settlements around rain pools, green valleys, and rivers.
The ancient climate shift and its effects are detailed in the July 21 issue of the journal Science.
http://www.livescience.com/4180-sahara-desert-lush-populated.html
Both the American Revolution and the French Revolution occurred during a "Little Ice Age."
The Little Ice Age (LIA) was a period of cooling that occurred after the Medieval Warm Period (Medieval Climate Optimum).[1] While it was not a true ice age, the term was introduced into the scientific literature by François E. Matthes in 1939.[2] It has been conventionally defined as a period extending from the sixteenth to the nineteenth centuries,[3][4][5] or alternatively, from about 1350 to about 1850,[6] though climatologists and historians working with local records no longer expect to agree on either the start or end dates of this period, which varied according to local conditions. NASA defines the term as a cold period between AD 1550 and AD 1850 and notes three particularly cold intervals: one beginning about 1650, another about 1770, and the last in 1850, each separated by intervals of slight warming.[7] The Intergovernmental Panel on Climate Change Third Assessment Report considered the timing and areas affected by the LIA suggested largely independent regional climate changes, rather than a globally synchronous increased glaciation. At most there was modest cooling of the Northern Hemisphere during the period.[8]
http://en.wikipedia.org/wiki/Little_Ice_Age
It's hard to attribute such climate changes to pollution caused by mankind. Even before we evolved our earth had many climate changes.
Snowball Earth
The snowball Earth hypothesis posits that the Earth's surface became entirely or nearly entirely frozen at least once, some time earlier than 650 Ma (million years ago). Proponents of the hypothesis argue that it best explains sedimentary deposits generally regarded as of glacial origin at tropical paleolatitudes, and other otherwise enigmatic features in the geological record. Opponents of the hypothesis contest the implications of the geological evidence for global glaciation, the geophysical feasibility of an ice- or slush-covered ocean,[2][3] and the difficulty of escaping an all-frozen condition. There are a number of unanswered questions, including whether the Earth was a full snowball, or a "slushball" with a thin equatorial band of open (or seasonally open) water.
The geological time frames under consideration come before the sudden multiplication of life forms on Earth known as the Cambrian explosion, and the most recent snowball episode may have triggered the evolution of multi-cellular life on Earth. Another, much earlier and longer, snowball episode, the Huronian glaciation, which occurred 2400 to 2100 Ma may have been triggered by the oxygen catastrophe.
http://en.wikipedia.org/wiki/Snowball_Earth
Realize that I am not denying that the enormous amount of pollution our civilization is throwing into our atmosphere might be causing some significant changes in our climate. Even if it isn't, it still causes significant health problems to those exposed to it. I was born in Pittsburgh Pa and my mother often told me that while she lived there she would have to often wash her window curtains as they had turned black from the soot from the steel mills. There were times long ago when the street lights were turned on at noon time because the pollution blocked out the sun.
Pittsburgh
The air in this steel town was once so polluted with coal and coke soot that streetlights were sometimes turned on at high noon. Now, much of Pittsburgh's pollution comes from Ohio, West Virginia and further west, according to Neil Donahue, who studies transport pollution at Carnegie Mellon University.
I grew up in a industrial town in northeastern Ohio. The fumes from the factories were so strong that it ate paint off the cars of the plant workers in the parking lots.
Therefore I am a strong supporter of efforts to find more environmentally friendly means to power our industry than fossil fuels. There are a lot of viable alternatives that are being developed today but unfortunately it may be impossible to greatly reduce our dependence on fossil fuels for another 20 to 30 years. All efforts to find better solutions should be financed and supported and if developed the technology should be shared with the world with little emphasis on financial profit.
What I fear is that the backers of "global warming" or "climate change" are developing a religion. While this approach does garner considerable support for the movement to reduce pollution and the consequent damage to our environment, it may hinder good science. Intermixing politics and science is a poor idea just as intermixing science with religion.
The bottom line is I feel that we both agree that our dependence on fossil fuels has to change. No matter how you look at it pollution has a negative effort on our environment. Our technology is advancing to the point that we can leave this addition behind and find a cheaper and far more efficient method of generating power that will be far healthier both to us and our planet.

The phrase "global warming" should be abandoned in favor of "climate change", Mr Luntz says, and the party should describe its policies as "conservationist" instead of "environmentalist", because "most people" think environmentalists are "extremists" who indulge in "some pretty bizarre behavior... that turns off many voters".

(133 posts)Kosaka and Xie recently published in Nature (doi:10.1038/nature12534) that the 'pause' in heating is likely due to equatorial surface cooling in the Pacific ocean.
Their abstract provides an excellent summary -
"Despite the continued increase in atmospheric greenhouse gas
concentrations, the annual-mean global temperature has not risen
in the twenty-first century1,2, challenging the prevailing view that
anthropogenic forcing causes climate warming. Various mechanisms
have been proposed for this hiatus in global warming36,
but their relative importance has not been quantified, hampering
observational estimates of climate sensitivity. Here we show that
accounting for recent cooling in the eastern equatorial Pacific reconciles
climate simulations and observations.We present a novel method
of uncovering mechanisms for global temperature change by prescribing,
in addition to radiative forcing, the observed history of sea
surface temperature over the central to eastern tropical Pacific in a
climate model. Although the surface temperature prescription is
limited to only 8.2% of the global surface, our model reproduces
the annual-mean global temperature remarkably well with correlation
coefficient r 50.97 for 19702012 (which includes the current
hiatus and a period of accelerated global warming). Moreover, our
simulation captures major seasonal and regional characteristics of
the hiatus, including the intensified Walker circulation, the winter
cooling in northwestern NorthAmerica and the prolonged drought
in the southernUSA.Our results show that the current hiatus is part
of natural climate variability, tied specifically to aLa-Nina-like decadal
cooling. Although similar decadal hiatus events may occur in the
future, the multi-decadal warming trend is very likely to continue
with greenhouse gas increase."
This gives an insight into the mechanics. Now about the ice, the National Snow and Ice Data Center has switched from their nominal average datum period 1979-2000 to a new thirty year average extending from 1981 to 2010. This thirty year average datum period has been adopted in other data sets as well.
The net effect is that the numbers as we have seen them change just slightly, an effect that the climate denial crowd has latched on to suggesting that the earth is actually 'cooling'.

(7,402 posts)Remember that day in March of last year when a town in upper Michigan broke their old high temperature for that day by 32 degrees. Thawing got an early, early start. This year March, April and May were below normal so we had less of a thaw. But the year, overall, has come out to be very normal -- not cool and not warm when taken as a whole. (The last 3 weeks have been seasonally very warm, getting us all of the way back to normal for the year.) Incidentally, the Greenland icecap saw a record thaw this year and that probably just means a shift in the location of the hot spot. That is the problem when making predictions based on a cherry picked single set of numbers. You simply ignore them and wait for a more comprehensive sample. (Is the Telegraph a right-wing paper on the other side of the pond)?

(3,811 posts)Observations over the past 5 years have shown a slowing down in the rate of warming. The actual warming rate over the past five years has been around 0.17 degC/decade. The mean warming rate predicted by the latest models was 0.23 degC/decade. The observed rate of warming is still within the predicted envelope -- it's just on the low side.
Despite what "some scientists" (who?) might allegedly suggest, a five year trend is not believed by the vast majority of climate scientists to be significant in the long term (the "long term" being the very definition of climate).
A minority of climate scientists have suggested that surface temperatures may be slightly less sensitive to carbon dioxide than the present models allow. But the general consensus is that five years of less than expected warming is not a falsification of our entire understanding of how "greenhouse gases" influence the planet's temperature.
Most scientists attribute the less than expected warming to a combination of a period of solar minimum and temporary ocean circulation patterns in the Pacific. We will be returning to a solar maximum in a few years and many scientists expect the warming to get back on pace, possibly aggressively.

There has been no "pause" in warming since 1997. The fact is, seven of the top 10 warmest years on record for the contiguous 48 states have occurred since 1998, and 2012 was the warmest year on record. http://www.epa.gov/climatechange/science/indicators/weather-climate/temperature.html

(100 posts)Professor Anastasios Tsonis, just remember physics 101. As long as there is ice, the temperature will not rise. The solar energy coming through will be spend melting the ice. Just think about your coke with ice drink. the drink will stay cool as long as there is ice. The very moment the last piece of ice melts, the temperature will start rising. Wait until the last piece of polar ice melts down, then start recording global temperatures. Until then, all you will notice is climate change, not temperature change. You are not considering heat transfer. Heat transfer can produce change of state (ice to water, water to vapor), and temperature change. I think you know that global warming is a multiple stage process. We are in the ice melting stage. Think about heat transfer, not temperature change.

(19,236 posts)If you look at the historical record of the last 150 years, you'll see frequent episodes where we warmed rapidly for a decade, leveled off or dropped slightly for a decade, and then warmed even more then following one.
It's been a puzzle for scientists for a while, with suggestions that it had to do with solar activity, sulfur pollution from coal plants, etc.
Now they think they've figured it (mostly) out: it's the Pacific La Nina effect: http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2013/08/28/la-nina-behind-gentler-global-warming-study-finds/
The heat we should be seeing in the atmosphere is instead being pumped into the deep oceans. Unfortunately, heating the deep oceans can result in changes in global currents, and also reduce the amount of CO2 the oceans can store in reserve (warm water holds less CO2 than cold water).
The scary thing, though, is that this effect is expected to only last to the end of this decade. And, even with a La Nina cooling trend, the planet is still seeing extreme weather effects already from climate change. As the oceans warm, they reach their CO2 saturation point more quickly, leaving more of the stuff in the air. After that: boom goes the dynamite.
