Også K&Ls sammenlignende diskussion af to væsentlige klimapåvirkere, CO2 og solaktivitet, er meget enøjet. For CO2 hævdes det, at molekylets egenskaber er velforståede, og at vi kender energipåvirkningen på planeten af den stigende CO2-koncentration med ca. 10 pct. nøjagtighed. Dette er ikke forkert, men alligevel misvisende.

Det er rigtigt, at den direkte drivhuseffekt af CO2 menes at være kendt så nøjagtigt, men den giver i sig selv ikke anledning til stor bekymring. Problemet er den kraftige forstærkning af opvarmningen fra en afledt ændring af luftens indhold af vanddamp og af skyerne, som er indbygget i modellerne.

Stop denying climate science and ACT! (before people realize it's a scam)

"Anyone dissenting from this "call to action" is a climate change "denier"—a pejorative devised to vilify and silence anyone who rejects this agenda, by linking our views to Holocaust denial. What nonsense.
...
What we deny are assertions that human carbon dioxide emissions have replaced the myriad of complex, interrelated planetary, solar and cosmic forces that caused previous climate reverberations, and that what we are experiencing now is unprecedented and likely to be catastrophic.

Not one of the alarmist claims is supported by actual observations or scientific evidence. Even worse, the claims are getting more ridiculous with every passing day: "children aren't going to know what snow is," crime is rising, oceans won't smell the same, and storms are getting worse—because of global warming."

Reality intrudes on a hot dream

The globe cools, and Al Gore's 'Climate Reality' does, too
...
The scorekeepers of global-warming alarmism, the U.N. Intergovernmental Panel On Climate Change, is about to release its fifth Assessment Report, which is said to admit that the planet has been cooling, not warming. A leaked draft version of the report concedes the very inconvenient truth, and casts doubt on the claim that man plays a role in triggering "extreme weather."

Det lyder jo som sød musik i ørene. Nu må vi bare håbe de ikke fortryder inden selve frigivelsen

Hvis det kommer til at fremgå lige så tydeligt i rapporten som det fremgår her, må politikerne da få travlt med at skifte kurs væk fra den alt for dyre grønne energi. En dobbeltbet til Dk som vedblivende er et for dyrt land at producere i med mindre vi altså går ned i løn...

Economic woes may mute impact of U.N. report saying warming manmade

"The strongest scientific warning to date that global warming is man-made may have a muted impact when it is released later this month with many governments more focused on nursing weak economies than on fixing the planet."

http://jyllands-posten.dk/international/ECE5926653/vandstanden-stiger-hurtigere-end-frygtet/


Lækkede FN-dokumenter afslører, at isen på Antarktis og Grønland smelter i uhørt høj fart.



Isen på Antarktis og Grønland forsvinder i et højere tempo end hidtil antaget, og det øger nu frygten for voksende vandstande.

Det er nogle af konklusionerne i et udkast til en meget omfattende FN-rapport, som er blevet lækket til Bloomberg.

I dokumentet fremgår det, at Grønlands smeltevand gennemsnitligt har øget verdens vandstande med 0,59 millimeter årligt de sidste 10 år. I den 10-årige periode forinden lød tallet kun på 0,09 millimeter - seks gange mindre.

I den tilsvarende periode har Antarktis smeltevand haft fem gange så stor effekt på vandstandene i det sidste årti.

Ice in Antarctica and Greenland is disappearing faster and may drive sea levels higher than predicted this century, according to leaked United Nations documents.

Greenland's ice added six times more to sea levels in the decade through 2011 than in the previous 10 years, according to a draft of the UN's most comprehensive study on climate change. Antarctica had a fivefold increase, and the UN is raising its forecast for how much the two ice sheets will add to Earth's oceans by 2100.

Et enkelt spørgsmål; Kristoffer, synes du virkelig, at dette er en lødig artikel?
Vi kan vel godt blive enige om, at denne figur giver et mere retvisende billede af hvor dette års isudbredelse placerer sig i forhold til de seneste års udvikling i isudbredelsen og et noget andet billede, end det artiklen, du refererer, giver:


Her kan man læse mere om de mange fejl i artiklen bl.a. at medforfatteren til den ene forsker, artiklen citerer for, at vi er på vej mod global cooling, afviser af deres forskning viser dette, ligesom artiklens snak om et krisemøde i IPCC er forkert.

Ja, ift. de seneste årtier har du ret.
Artiklen gør da også ret tydeligt opmærksom på at der er tale om en sammenligning mellem i år og sidste år.
Hvordan tror du at isudbredelsen har ændret sig under den lille istid eller hvordan ville du forvente isudbredelsen ændrede sig siden det Holocæne klimatiske optimum?

Der er meget stærk evidens for at vi sammen med solens kommende dvale kan forvente MEGET kolde vintre, samt ekspansion af den arktiske havis.

Den amerikanske forskningsorganisation NOAA (National Oceanic and Atmospheric Administration), som netop forsker i havforhold og -udvikling, inklusive havtemperaturudviklingen, dokumenterer på sin hjemmeside (www.nodc.noaa.gov), med reference til peer-reviewed (fagfællebedømte) videnskabelige artikler bl.a. publiceret i det anerkendte amerikanske tidsskrift Geophysical Research Letters af Levotus et al. (2012), hvordan varmeindholdet i havene netop er steget gennem de seneste ca. 50 år (fra 1955 til 2010). Det gælder både i dybderne 0-700 m og 0-2.000 m og er objektivt bestemt ud fra historiske data samt observationer.


Det er vigtigt at huske på, at det er "dataene, der fortæller historien".

Men hvor meget kan man bruge den sammenligning til? Du vælger at citere artiklen og bringe et billede, der viser udviklingen fra 2012 til 2013. Synes du denne udvikling over et år er særlig relevant for det vi diskuterer på denne side nemlig klima?

Hvordan tror du at isudbredelsen har ændret sig under den lille istid eller hvordan ville du forvente isudbredelsen ændrede sig siden det Holocæne klimatiske optimum?

Jeg er blot en simpel lægmand, men hvis de to perioder du beskriver, begge er perioder, hvor det blev koldere, så ville jeg tro, at isudbredelsen voksede i de to perioder.

Der er meget stærk evidens for at vi sammen med solens kommende dvale kan forvente MEGET kolde vintre, samt ekspansion af den arktiske havis.
Forventer du seriøst at den linære trend du henviser til kan ekstrapoleres ud i fremtiden?

Mener du hermed, at du forventer, at de globale temperaturer kommer til at falde betydeligt de kommende år som følge af et muligt fald i solintensiteten? Som jeg har forstået forskningen via IPCC's rapporter, så er forcing fra ændringer i solintensiteten forholdsvis små sammenlignet med forcing fra drivhusgasser:

IPCC skriver i AR4:

Calculations with three-dimensional models (Wetherald and Manabe, 1975; Cubasch et al., 1997; Lean and Rind, 1998; Tett et al., 1999; Cubasch and Voss, 2000) suggest that the changes in solar radiation could cause surface temperature changes of the order of a few tenths of a degree celsius.

Ligesom man her kan se den klassiske IPCC figur over de forskellige forcings betydning.

Hvis du mener at IPCC's figur over forcings stadig er retvisende, så har du sandelig en stor mængde nyere litteratur som du skal til at læse igennem om bla. reduceret klimasensitivitet, aerosolmængde samt effekt og som rapporteret andetsteds her på siden:

Veretenenko and Ogurtsov, 2013. Stratospheric Polar Vortex as a Possible Reason for Temporal Variations of Solar Activity and Galactic Cosmic Ray Effects on the Lower Atmosphere Circulation. Advances in Space Research (in press).

Abstract
Possible reasons for a temporal instability of long-term effects of solar activity (SA) and galactic cosmic ray (GCR) variations on the lower atmosphere circulation were studied. It was shown that the detected earlier ~60-year oscillations of the amplitude and sign of SA/GCR effects on the troposphere pressure at high and middle latitudes (Veretenenko and Ogurtsov, Adv.Space Res., 2012) are closely related to the state of a cyclonic vortex forming in the polar stratosphere. The intensity of the vortex was found to reveal a roughly 60-year periodicity affecting the evolution of the large-scale atmospheric circulation and the character of SA/GCR effects. An intensification of both Arctic anticyclones and mid-latitudinal cyclones associated with an increase of GCR fluxes at minima of the 11-year solar cycles is observed in the epochs of a strong polar vortex. In the epochs of a weak polar vortex SA/GCR effects on the development of baric systems at middle and high latitudes were found to change the sign. The results obtained provide evidence that the mechanism of solar activity and cosmic ray influences on the lower atmosphere circulation involves changes in the evolution of the stratospheric polar vortex.



Så jo, jeg er fuldstændigt overbevist om at solens faldende aktivitet vil medføre koldere klima og især i Nordeuropa, hvilket er underbygget af en masse peer-reviewet litteratur og simple observationer.

Nu skal vi jo heldigvis ikke vente længe på nyt fra IPCC, så må vi se, hvad de siger om dette.

Fair nok, men jeg forstår stadig ikke, hvorfor du linker til en underlødig Daily Mail-artikel, der gør et stort nummer ud af ændringer fra et år til et andet. Det synes jeg i hvert fald ikke på nogen måde underbygger din holdning, med mindre du mener, at stigningen i isudbredelsen fra 2012 til 2013 er et forvarsel om den fremtidig trend og kommende koldere klima og ikke blot et udtryk for "regression toward the mean" efter en rekordlav udbredelse sidste år.

Jeg gør mig ingen forestillinger om, at jeg skulle kunne hamle op med din viden og antallet af læste artikler. Men jeg kan blot konstatere, at jeg uden besvær kan finde en hel række studier, der viser, at solen kun har haft en beskeden betydning de seneste årtier:

A science-based rebuttal to global warming alarmism

Among the key findings of CCR-II are:

*Doubling of CO2 from its pre-industrial level would likely cause a warming of only about 1oC, hardly cause for alarm.

*The global surface temperature increase since about 1860 corresponds to a recovery from the Little Ice Age, modulated by natural ocean and atmosphere cycles, without need for additional forcing by greenhouse gases.

*There is nothing unusual about either the magnitude or rate of the late 20th century warming, when compared with previous natural temperature variations.

*The global climate models projected an atmospheric warming of more than 0.3oC over the last 15 years, but instead, flat or cooling temperatures have occurred.

The science presented by the CCR-II report directly challenges the conclusions of the IPCC. Extensive peer-reviewed evidence is presented that climate change is natural and man-made influences are small. Fifteen years of flat temperatures show that the climate models are in error.

De to første punkter virker selvmodsigende; enten fører en fordobling af CO2 til en temperaturstigning på 1 grad eller også skyldes temperaturstigningen vi har set naturlig variation, og klimasensitiviteten er 0.

Lidt fra the Guardian om den arktiske is

Both articles claimed that Arctic sea ice extent grew 60 percent in August 2013 as compared to August 2012. While this factoid may be technically true (though the 60 percent figure appears to be an exaggeration), it's also largely irrelevant. For one thing, the annual Arctic sea ice minimum occurs in September – we're not there yet. And while this year's minimum extent will certainly be higher than last year's, that's not the least bit surprising.


http://www.theguardian.com/environment/climate-consensus-97-per-cent/2013/sep/09/climate-change-arctic-sea-ice-delusions

Og en Greenpeace Rapport omkring klima-benægterne (Vi behøves ikke at have diskussionen for/imod igen, men artiklen kan jo åbne en konstruktiv diskussion omkring de benyttede metoder hos diverse lejre i klimadebatten.)

It writes boilerplate legislation, runs extensive PR campaigns, puffs CVs with fake credibility, facilitates or promotes the intimidation of climate scientists and advocates, publishes books, organises speaking tours and conferences, gets on the telly and radio a lot, uses Freedom of Information laws as a surveillance tool, pays scientists to speak and - crucially - it manufactures doubt and confusion among policy makers, politicians and the public about climate change.

Ja, beklager min betegnelse. Og jeg giver dig da ret, jeg synes også at Klima-alamister (nu kalder jeg dem med den betegnelse) ikke altid holder en sober tone. Og her synes jeg også at Greenpeace kan være lidt for meget.

Det interessante er jo ikke figuren, for man kunne have vist perioden 1990 - 2013 og den vil vise noget andet. Nå ja, det er en længere periode. Så kunne man vise 2011-1013 og man ser noget andet. For mig er det ligegyldigt. Det er jo ikke figurens indhold som det kommer an på.

Det interessante er jo at du viser netop denne figur, som i andre topic i dette forum er blevet diskuteret igen og igen. Og lige præcis her falder du med din figur jo i. Man kan jo altid finde en figur og vise den igen og igen, og det er jo et af punkterne i Greenpeace' rapport.

Et interessant interview med klimaforsker professor Hans von Storch i Deutschlandfunk d. 9.9.2013.

Da Storch er tæt tilknyttet IPCC.vækker hans udtalelser altid opsigt i kredsen af etablerede klimaforskere.

Storch stiller sig kritisk til klimamodellerne og mener,at man ikke har taget nok hensyn til naturlige klimaændringer og måske har overvurderet CO2s klimapåvirkning,måske indvirker her stærkere faktorer,man kunne f.eks. tænke på Solen,siger han.

Storch siger videre: i modellerne indbygger vi egentlig kun effekten af drivhusgasserne;men vi tager f.eks. ikke hensyn til den systematisk fremtidige ændring af Solens ydelse.

Dialing Back the Alarm on Climate Change

"A forthcoming report points lowers estimates on global warming
Later this month, a long-awaited event that last happened in 2007 will recur. Like a returning comet, it will be taken to portend ominous happenings. I refer to the Intergovernmental Panel on Climate Change's (IPCC) "fifth assessment report," part of which will be published on Sept. 27.
There have already been leaks from this 31-page document, which summarizes 1,914 pages of scientific discussion, but thanks to a senior climate scientist, I have had a glimpse of the key prediction at the heart of the document. The big news is that, for the first time since these reports started coming out in 1990, the new one dials back the alarm. It states that the temperature rise we can expect as a result of man-made emissions of carbon dioxide is lower than the IPPC thought in 2007."

Global warming is just HALF what we said: World's top climate scientists admit computers got the effects of greenhouse gases wrong

-Leaked report reveals the world is warming at half the rate claimed by IPCC in 2007
-Scientists accept their computers 'may have exaggerated'

A leaked copy of the world's most authoritative climate study reveals scientific forecasts of imminent doom were drastically wrong.

The Mail on Sunday has obtained the final draft of a report to be published later this month by the UN Intergovernmental Panel on Climate Change (IPCC), the ultimate watchdog whose massive, six-yearly 'assessments' are accepted by environmentalists, politicians and experts as the gospel of climate science.

They are cited worldwide to justify swingeing fossil fuel taxes and subsidies for 'renewable' energy.

Yet the leaked report makes the extraordinary concession that the world has been warming at only just over half the rate claimed by the IPCC in its last assessment, published in 2007.

Global warming advocates may be more Nostradamus than Galileo

Those of us who are skeptical of man-made abrupt climate change are often accused of being hostile towards science. We're told that the facts prove our world is on an unprecedented and nearly irreversible warming trend and mankind is largely responsible. If we don't believe that, they say, then we're basing our skepticism on ideology rather than climatology.

The advocates of global warming theories, however, style themselves as unbiased observers who form their beliefs through the scientific method and remain immune from personal perspectives, political influences or simple mistakes. They're the enlightened Galileo, while we're his ignorant and superstitious inquisition. But if their observations change – if the facts change – would these unbiased observers change their theories as well?

Here are some recent inconvenient facts for them to consider:

Alabama had one of its coolest summers on record, averaging 87.87-degrees during June, July and August. In fact, weather monitors throughout the state didn't record a 100-degree measurement for the third time in the last dozen years, according to data released this month by John Christy, director of the Earth Systems Science Center at the University of Alabama in Huntsville. Moreover, six of the state's coolest summers have been within the last 20-years, according to the Office of Alabama Climatology.

Worldwide, there was a drop in the average temperatures in the lower stratosphere for 2012, according to the National Oceanic and Atmospheric Administration. It reported that last year was "nearly the coldest on record in the lower stratosphere since records began."

Restoring facts to climate science

The U.N. panel has been corrupted by government lucre

On Sept. 27, the United Nations will issue its next major climate change report. Last month's leak of a draft indicates that it will be full of warnings of catastrophe to come if we do not quickly change our ways. Here is a sample:

"Changes are projected to occur in all regions of the globe, and include changes in land and ocean, in the water cycle, in the cryosphere, in sea level, in some extreme events and in ocean acidification. Many of these changes would persist for centuries. Limiting climate change would require substantial and sustained reductions of [carbon-dioxide] emissions."

The report, titled "Working Group I: The Physical Science Basis," is the first volume of a series of documents that will be issued by the U.N. over the next year as part of the Fifth Assessment Report of the U.N. Intergovernmental Panel on Climate Change (IPCC).

When the panel published previous assessment reports in 1990, 1995, 2001 and 2007, most in media, government and the public regarded their conclusions as irrefutable, the most authoritative, up-to-date word from thousands of scientists in the field. However, things may be very different this time around. Since the last report, the current period of no global warming has extended to 17 years. This has occurred despite the continuing rise in carbon-dioxide levels, something none of the organization's climate models predicted.

Other alarming forecasts — increasing tropical cyclones and tornadoes, rapid sea-level rise and sudden ice melt — have not come about.

But as the campaign gets underway, a new report from the world's leading climate scientists could leave environmentalists on the defensive, and the "deniers" more confident and assertive.

"HOLDING CLIMATE CHANGE DENIERS ACCOUNTABLE" read the headline of a League of Conservation Voters press release announcing a $2 million barrage of ads aimed at Republican Sen. Ron Johnson, as well as GOP Reps. Mike Coffman, Dan Benishek and Rodney Davis. "We're changing the terms of the climate change debate," said an LCV spokesman. "It's no longer acceptable to be a member of Congress and deny basic science."

Finally, the IPCC has toned down its climate change alarm. Can rational discussion now begin?

Next week, those who made dire predictions of ruinous climate change face their own inconvenient truth. The summary of the fifth assessment report by the Intergovernmental Panel on Climate Change (IPCC) will be published, showing that global temperatures are refusing to follow the path which was predicted for them by almost all climatic models. Since its first report in 1990, the IPCC has been predicting that global temperatures would be rising at an average of 0.2° Celsius per decade. Now, the IPCC acknowledges that there has been no statistically significant rise at all over the past 16 years.

Warming Plateau? Climatologists Face Inconvenient Truth

Data shows global temperatures aren't rising the way climate scientists have predicted. Now the Intergovernmental Panel on Climate Change faces a problem: publicize these findings and encourage skeptics -- or hush up the figures.

For a quarter of a century now, environmental activists have been issuing predictions in the vein of the Catholic Church, warning people of the coming greenhouse effect armageddon. Environmentalists bleakly predict global warming will usher in plagues of biblical dimensions -- perpetual droughts, deluge-like floods and hurricanes of unprecedented force.

The number of people who believe in such a coming apocalypse, however, has considerably decreased. A survey conducted on behalf of SPIEGEL found a dramatic shift in public opinion -- Germans are losing their fear of climate change. While in 2006 a sizeable majority of 62 percent expressed a fear of global warning, that number has now become a minority of just 39 percent.

One cause of this shift, presumably, is the fact that global warming seems to be taking a break. The average global temperature hasn't risen in 15 years, a deviation from climatologists' computer-simulated predictions.

Når FN's klimapanel på fredag præsenterer deres rapport om verdens tilstand, bliver der kastet lys over en ofte overset pointe. Temperaturstigninger er ikke bare temperaturstigninger. Temperaturen på land er ikke det samme som havtemperaturen, og mens landtemperaturen forsætter med gradvist at stige, så accelererer havtemperaturen.

Nu begynder Connie Hedegaard også at tvivle på IPCCs klima-katastrofe forudsigelser.

Om en uge kommer den næste store klimarapport fra IPCC om de fysiske årsager til klimaforandringer – den femte af slagsen siden 1990. Det bør blive den sidste. Det er på tide at bede organisationen om at aftræde fra aktiv tjeneste i klimaets interesse. Det skal ske samtidig med en tak for den store indsats med at forklare verdenssamfundet, at klimaforandringer er reelle, og at de ud over naturlige variationer også er forårsaget af menneskeskabte handlinger, først og fremmest ved store udledninger af CO2 til atmosfæren.
