Decline in solar output unlikely to offset global warming: study
(PhysOrg.com) -- New research has found that solar output is likely to reduce over the next 90 years but that will not substantially delay expected increases in global temperatures caused by greenhouse gases.
Carried out by the University of Reading and the Met Office, the study establishes the most likely changes in the Sun's activity and looks at how this could affect near-surface temperatures on Earth.
It found that the most likely outcome was that the Sun's output would decrease up to 2100, but this would only cause a reduction in global temperatures of 0.08 °C. This compares to an expected warming of about 2.5 °C over the same period due to greenhouse gases (according to the Intergovernmental Panel on Climate Change's B2 scenario for greenhouse gas emissions that does not involve efforts to mitigate emissions).
Gareth Jones, a climate change detection scientist with the Met Office, said: "This research shows that the most likely change in the Sun's output will not have a big impact on global temperatures or do much to slow the warming we expect from greenhouse gases.
"It's important to note this study is based on a single climate model, rather than multiple models which would capture more of the uncertainties in the climate system."
The study also showed that if solar output reduced below that seen in the Maunder Minimum - a period between 1645 and 1715 when solar activity was at its lowest observed level - the global temperature reduction would be 0.13C.
During the 20th Century solar activity increased to a grand maximum' and recent studies have suggested this level of activity is at or nearing its end.
Professor Mike Lockwood, an expert in solar studies at the University of Reading, used this as a starting point for looking at the most probable changes in the Sun's activity over the 21st Century.
Met Office scientists then placed the projections into one climate model to see how they may impact temperatures.
Professor Lockwood said: "The 11-year solar cycle of waxing and waning sunspot numbers is perhaps the best known way the Sun changes, but longer term changes in its brightness are more important for possible influences on climate.
"The most likely scenario is that we'll see an overall reduction of the Sun's activity compared to the 20th Century, such that solar outputs drop to the values of the Dalton Minimum (around 1820). The probability of activity dropping as low as the Maunder Minimum - or indeed returning to the high activity of the 20th Century - is about 8%. The findings rely on the assumption that the Sun's past behaviour is a reasonable guide for future solar activity changes."
Peter Stott, who also worked on the research for the Met Office, said: "Our findings suggest that a reduction of solar activity to levels not seen in hundreds of years would be insufficient to offset the dominant influence of greenhouse gases on global temperatures in the 21st century."

A. Stott (2012)), is published online in the Journal of Geophysical Research and can be seen here: http://www.agu.org … 017013.shtml

Is that why global temperatures have been stable for the past 15 or so yrs and more recently slowly falling?
Let's hope that Earth's temperature DOESN'T fall to those experienced in the Dalton and especially Maunder minimum because the economic impact on ALL of us will be devastating, as it was during those periods.
Though Stott et al are believer's that GHG's have some "dominant effect" on earth's temperature (what else, they work for the Met Office) that evidence is weak and of poor quality and is getting weaker with nearly every new study (not model, study).

That's correct. We are almost at the peak of a max, but it's one of the weakest and shortest peaks we have seen in recorded history.
One interesting point about the index we use to measure solar activity is that we use sun spots as an indicator. When sun spots go all the way down to zero, we have no way to know if the sun continues to go down lower, or how far down it goes. All we can see is that it gets down to the point where there's no sun spots, then we lose that indicator. There are a couple other things they look at besides sun spots, but losing one of the few visible indicators makes things tricky for space weather experts.
If decreased solar activity won't slow global warming, and the Earth doesn't warm as much as expected in the next few decades, then what? Question only.

The GISS graphs you linked to (first link broken) do show a flat trend for the past 10-15 years. Some records, such as the UAH satellite record show a longer flat trend. GISS is mostly a land record though, so it's expected that it will look different than a satellite record.
However, the trend over the past 10-15 years doesn't really mean anything. Anything less than 30 years is just noise. You have to look at at least 30 years, and there's certainly been an increase in temp over the past 30 years, no matter who's data you use.

Prior to the industrial age, CO2 PPM rose post warming, the present rise coincides with the warming so even if the warming is natural, our activities have both amplified it and extended it's duration.

Every other survey done in the past showed that education has little to do with how people feel about the environment or conservation. The main factor has always been shown to be political and social preference, and most issues are split just about dead down the middle, 50/50.
My usual word of caution in relation to surveys though: Be very carefull what you are reading and examine the methods with a microscope, then compare that to what their finding were. In polls and surveys, the slightest change in method can cause huge changes in the result, and conversely, two different studies showing the same result can have very different meanings if the methods were different.

There may also be tipping points (e.g., release of methane from permafrost or clathrates) that do go over unity until trapped methane used up (see PETM).

How bad could it get? There is at least an order of magnitude more methane locked up in clathrates than all the fossil fuels that we have burned, and methane is a far more potent green-house gas than CO2.
Still, even releasing this would not be as bad as the Yucatan impact. We have a good idea of what the result would be - it would look like the PETM. In the PETM the planet warmed between 5C and 10C, with the arctic warming 15C-20C. Current sea levels would rise ~100 meters.
That's more of a temperature change than an ice age, but it did not wipe out as much life as the Yucatan impact and the Deccan traps.

I am confident that with the rate of progress in climate modelling and computing power, we will soon have a pretty good understanding of the impact of CO2 and other GHGs, of ocean currents, of the sun, and other factor, and will be able to make pretty accurate predictions and run what-if scenarios.
And I am confident that big energy companies will figure out how to make big money from renewable energy, and that once when they do renewable energy will grow very rapidly. In fact it is already growing fast enough - if solar continues its growth rate for 40 years, it will deliver several times the energy that humanity uses today.
Science is very good at solving crises, so once it becomes a crisis we will figure out how to react fast.
And what if we are currently preventing an ice age? (remember, a single ice age can ruin your whole day).
We need to earth's understand climate, and to then control what we release into the atmosphere accordingly.

I'm not as optimistic as RealS is about big energy coming to the rescue. The way I see it, there will be a huge massive shift to a (near) all-electric society as peak oil comes in full to play. But that means using more cheap and abundant coal (and lack of wisdom to solve a longer term problems of AGW/CO2).

Thanks for the clarification - an emoticon would have made it clear to start with.
Your story of poking the bear is a good one - it should be in the Darwin awards.
The feedback that worries me is the methane, both in permafrost and on the sea bed. The other feedbacks are either not plausible at this time (Venus-style dissociation of carbonates), or are self limiting (decrease in albedo from melting ice stops when the ice is gone).
The methane is a time bomb that nature has accumulated. We are currently playing with fire near the fuse.
However that much natural gas is potentially a huge resource worth many trillion of dollars. The energy companies could make a few trillion dollars by defuse a millions-of-years-old time bomb while supplying us with cleaner energy (enough energy that we could afford some of it to sequester the CO2).
As other fossil fuels get scarce, big energy SHOULD go after this huge resource.

You don't.
WEATHER is an emergent system where the number of significant variables grows very rapidly with the timescale of the forecast.
CLIMATE is also hugely complex, but longer timescales add only modest numbers of significant factors (longer-term feedback effects).
For example, all our computing/modelling power cannot tell me whether July 4th this year will be sunny or rainy where I live - that's weather, dominated by chaos. But unless we have a huge volcano or asteroid strike, everywhere within a thousand miles every day in July will be warmer than any day in January - that's climate, dominated by a few factors.
Getting PRECISE and LOCAL climate predictions would greatly increase the number of significant factors, but for AGW we just need to know the direction and MAGNITUDE of the natural changes and of GHG impact.

Unless we would otherwise be entering an ice age (which you might have noticed I consider possible), the problem is GHGs in general. That includes water vapor (the dominant greenhouse gas) as well as CO2 and methane. Talking about one GHG doesn't mean that other GHGs are not important, and you KNOW that.
Have you read up on the PETM? Have you read up on how much methane trapped in clathrates and below the permafrost? Have you read about the relative warming effects of methane and of CO2?
CO2 traps heat. Heat evaporates water, which traps more heat. Heat melts ice to water, absorbing more heat. Heat also speeds up decay, releasing CO2, which traps more heat. These amplify the effect of the original CO2 by an amount between 1x and 4x (best estimate ~2.5x).
But if heat starts releasing methane, that amplification could get MUCH higher.

We need to be able to EITHER cut back our GHG (and soot) emissions to control warming, or to increase emissions to prevent an ice age (right now the best estimates are that we need to cut back, and fairly rapidly). And we need to KNOW what the sun and our orbit would do and how much GHGs would prevent something catastrophic.
We couldn't yet do much to counteract major volcanic activity, but we are now powerful enough to smooth out the effects of the earth's orbit and what we have seen of the sun's variability (as for humanity not being able to affect the atmosphere and the climate, that's BULL).

How much heat is 'trapped' over a dry desert at night? Not much.
Jan 31, 2012
Rank: 4.2 / 5 (5)
Water vapor is the dominant green house gas, so in a dry desert there is much less heat trapping. But CO2 still traps about 1.6 Watts per square meter on the average..
That's not a huge amount - a black body at 0C/32F radiates 315 W/m2, and the average land on earth a good fraction of that, so it's a bit under 1% of the radiation sent out that CO2 DIRECTLY traps.
So your 'No it does not' is wrong, but your 'not much' is correct.
However the impact over non-desert is much larger because the bit of warming from that trapping lets the air hold more moisture, and water vapor is a stronger GHG than CO2.
HOW much larger is not known, but best estimates are ~2.5x

The estimates are currently good enough to warrant the precautionary principle: RECENT TRENDS ARE WARMING, SO MINIMIZE OUR WARMING IMPACT UNTIL WE KNOW WHAT WE ARE DOING.
But there is a lot of work to do to understand whether we still need some warming to prevent an ice-age or whether we now need some cooling to prevent runaway warming.
Where NP really screws up is that he doesn't even want more research because he thinks that modelling is futile and that we are doomed by an ice-age anyway.
As for R2, I agree with him that IF (a big if) we had a level playing field and the IF impacts were known, private enterprise would fix the problem faster than government.
But R2 shouldn't ignore the KNOWN parts of the science.

Albedo changes are a lot larger.
"The annual average albedo declined very gradually from 1985 to 1995, and then declined sharply in 1995 and 1996. These observed declines are broadly consistent with previously known satellite measures of cloud amount.
The low albedo during 1997-2001 increased solar heating of the globe at a rate more than twice that expected from a doubling of atmospheric carbon dioxide. This dimming of Earth, as it would be seen from space, is perhaps connected with the recent accelerated increase in mean global surface temperatures."

How many photons/sec are being radiated by a gray body at 300K? Are all captured by those few CO2 molecules?
If more CO2 is in the atm, how many more photons are absorbed and re-radiated and does it matter much?
Feb 01, 2012
Rank: 5 / 5 (3)
The 15um-ish photons are almost all outward bound, because the peak of the spectrum of the earth at ~300K is near 15um.
In the simplest case, after a typically-outward-bound 15um-ish photon is absorbed by a CO2 molecule, the molecule re-radiates a 15um-ish photon in a random direction. If that new photon happens to be outward-bound, then no the CO2 had no impact. But half of the re-radiated photons will be inward-bound, and will carry that energy back to the earth (anything horizontal gets reabsorbed and re-radiated until it is either outward-bound or inward-bound.
It's more complex because the CO2 is not all in one layer, some photons get through, and not all re-radiated photons are at the same wavelength, but the basic principle holds that the more CO2 there is, the more 15um-ish photons are bounced back toward earth, leading to net warming. It's actually easy enough to model that it was worked out by hand before computers.

Photonic energy is quantized. An absorbing body can neither absorb nor re-radiate a photon of an arbitrary wavelength.
Spontaneous re-radiation is omnidirectional, so that half, ignoring Earth's curvature and the altitude at which such occurs, of all IR absorbed by atmospheric compounds is directed Earthward.

Rank: 5 / 5 (3)
The direct effects matter a bit, but not a huge amount because CO2 is not that great an IR absorber, and outside of a narrow window H2O would have absorbed most of the photons anyway.
The danger is the INDIRECT effects - the warmer air holds more H2O, which is a stronger GHG than CO2. Warmer air also melts more snow and ice, lowering the planet's albedo.
And some feedbacks are more copmplex - warmth also encourages plant growth, which warms the earth by lowering its albedo but also absorbs CO2, and the extra H2O creates more clouds which raise the albedo during the day but trap heat at night.
And the dangerous one is methane, which is a much more potent GHG than CO2 and is often trapped by cold temperatures (permafrost and clathrates), and MIGHT lead to runaway warming up to 5C-10C.
While the direct effects are known, the indirect effects are merely estimates with a high degree of uncertainty.

But if the temperature rises, the peak BB curve shifts to the left and the actual number of 15um photons bouncing about won't change much.
I notice most of the 'evidence' is quite empirical with little or no lab data. Something which should be quite easy to measure.
Bottom line is that CO2 is easy to measure in the atm as it is well mixed so, viola, the computer models are 'adjusted' to tag CO2 as the culprit because it is too difficult to measure water vapor and on orbit radiometers are still quite crude. The are crude since both NPL and NASA want to orbit radiometers that are NIST traceable. Current systems are not.

Accurate data has been kept since 1959, and CO2 has gone up by 76 ppm since then. 1 ATM = 14 PSI = ~1 ton per square foot, 76 ppm is 76 * 2000 / 1,000,000 psf = 0.152, or 2.4 oz per square foot, or 21 ounces per square yard.
Extra heavy denim (blue-jean jacket) material is typically only 16 oz per square yard.
So by WEIGHT we have added enough CO2 to cover the entire planet with a jacket, just since 1959.
Clearly that much material COULD trap a lot of heat, but CO2 really isn't that strong a GHG. So the DIRECT effect of the CO2 alone is a bit less than 1K.
The indirect effects are much less certain, and are mostly done by curve fitting, with the best fit totaling a 2.5x amplification of the direct effects.
And we are putting out CO2 faster and faster these days.

@r2 - a few seconds with Google would find you the absorption spectrum of CO2. Here is a nice, simple image for you. As you can see, the ~13um-~15um absorption band is broader than the 4.2um one that you call 'absorbing quite well':
http://www.bom.go.../4.shtml
Note that the ~13-~15um CO2 peak corresponds to a window in H2O's absorption which is near the peak of 255K thermal emissions.
Also your point about how much heat H2O vapor traps and how much more H2O warm air holds is exactly one of the indirect feedbacks amplifying CO2's modest direct warming potential.
You have just highlighted that the DIRECT warming from CO2 allows the air to hold additional H2O which adds INDIRECT warming.

1 ATM is ~100,000 N/m2 = ~10 N/cm2 = ~1 kg/cm2 = ~1000 grams/cm2.
~1000 grams of air (N2 with some O2) is ~1000g/cm2 / 29g/mole = ~34 moles/cm2 = ~34 x 6E23 = ~2E25 molecules per cm2.
The 108 ppm increase in CO2 is measured in molecules (not by weight), so each ppm is ~2x10^19 molecules/cm2 and 108 ppm is ~2x10^21 molecules per cm2.
So to answer your question, humans have ADDED roughly 2E21 (2,000,000,000,000,000,000,000) molecules of CO2 per cm2 to the atmosphere.
And yes, 2e21 molecules could easily trap 10e17 photons per second...
Do you now admit that doing the math that YOU asked for SUPPORTS rather than REFUTES that CO2 could have the impact ascribed to it?

If you were a farmer deciding which crops to plant, you could lose your crops if you took YOUR trend and predicted continued warming.
If the same farmer looked the TRENDS hoe would pick a crop that does better int cooler periods because the trend for the next 20-30 years will be negative.
Maybe 30 years from now natural recovery from the LIA will start again in the same way there was a decade and half of warming after the 40 years of cooling from 1940 to 1980.
But considering how weak SC24 is and how miniscule SC25 will be, I'll bet on 50-100 years of cooling.

Recently exposed remains of plants that had been buried under Baffin Island ice for centuries provided the crucial clue that has led an international team of researchers to conclude the Little Ice Age was triggered by volcanic eruptions between AD 1275 and 1300 and was sustained by changes in Arctic sea-ice cover that lasted several centuries."

Later, a cooling period occurred from 1766 to 1898, with a peak between 1857 and 1871, during which the glacier advanced up to 8 km into the interior of the Laguna San Rafael.

1'C lower than the current temp which is 0.74'C higher than the standard. That makes the LIA in Africa up to 0.26'C cooler than the modern standard.
So much for your dishonest claim of a 10'C cooling.

Evidence for cause of Little Ice Age found in Canadas North
So now you know the principle trigger of the LIA. It wasn't a decrease in solar output as denialists have continually claimed. It wasn't a decrease in CO2 levels as denialists have continually implied. It wasn't caused by space aliens or cosmic rays, or hoards of goats, or whatever other mindless claptrap that comes into your brainless skulls.
It was triggered by a series of volcanic eruptions which caused a largely hemispheric cooling which was then amplified by positive feedback effects of ice.

Wait ... the globe spanning synchronous Little Ice Age occurred??????
I thought you were denying that right up until a few hours ago!!!!!!!
Wow. VD finally gives in on one of the most crucial points.
Since the globe spanning synchronous Little Ice Age DID OCCUR, then all proxies that do not show the globe spanning synchronous Little Ice Age are invalid.

Ahhh. Volcanoes Solar change = LIA. Sounds quite reasonable.
"we can conclude that multi-decadal average summer temperatures never returned to those of Medieval times until the 20th century,"
So the MWP was just as warm as today. Then the LIA occurred all around the globe and cooled off the planet and all warming since the globally synchronous Little Ice Age was just the planet returning to normal.

Yup, and it lowered global average temperatures by about 0.2'C
above the baseline.
Currently global average temperatures are 0.74'C above the baseline.
As your own references have shown, and which you have chosen to ignore, is the fact that the cooling - as I have repeatedly said - was largely regional, and despite your failed attempts to lie about the cooling being 10'C cooler than normal, even in the coldest regions of Europe, the average cooling was no more than 0.4'C cooler than the baseline.
Now your lie is in claiming that I had said that the LIA never occurred, when in fact I have repeatedly stated the fact that the LIA was largely a regional cooling, a fact that YOUR OWN REFERENCES HAVE VERIFIED.
The fact that your lies have been so thoroughly exposed BY YOUR OWN REFERENCES - and yet you continue to repeat them, is proof that you are mentally ill.

"Without fully discounting the influence of the solar radiation cycle on the medieval cooling trend, the researchers found, however, clear indications on Baffin Island that mosses and other plants that had thrived in the centuries prior to AD 1300 were suddenly killed during a time marked by cataclysmic discharges from volcanoes erupting in the Southern Hemisphere.
A similar series of tropical volcanic eruptions around the year AD 1450 which initially blocked sunlight but also extended Arctic ice cover and increased iceberg production in the North Atlantic coincided with another pulse of icefield growth and the flash-freeze killing of plants at different locations on the Nunavut island."
Since when does a .2C drop cause the flash-freeze killing of plants.

"I think when VD claims that the LIA was .2C colder and reputable scientists describe the drop in temperature as being so cold it could flash freeze plants" - Parker Tard
The first snow fall of every year flash freezes plants. They only thaw if the snow melts.
In addition the 0.2'C cooling of the LIA is a global average. Parker Tard seems to think that it is proper to compare regional averages with global averages, and on top of this he provides references that show a regional 0.4'C cooling in central Europe during the LIA to support is idiotic claim that temperatures were 10'C colder during that period.
Parker Tard is clearly suffering from a mental illness.

@NP - You take things out of context or misinterpret things, and from how frequently and repeatedly you do it I suspect that it is deliberate.
For example, here VD clearly states that the GLOBAL impact on CLIMATE (decades) is 0.2C.
However flash-freezing of plants is a SHORT-TERM impact found in areas not too far from the eruptions.
A big eruption that blocked sunlight for weeks in the arctic could easily flash-freeze plants (by directly lowering the temperature or by shifting weather patterns to bring in colder air), and yet after the tropospheric dust settled the GLOBAL MULTI-DECADAL impact of the stratospheric dust could be only 0.2 degrees.
So do you REALLY not understand the difference, or are you dishonest in pretending to not understand the difference?

And offers nothing as proof.
I offerred actual thermometer data that shows some winters were 7C colder during the LIA.
How could anyone in their right mind suggest .2C could cause a Little Ice Age is beyond me.
.2C is about the average difference in temperature from Aug 15th to August 18th in the UK. Totally unnoticeable.
I would say arguing that .2C would cause a mini ice age is about the stupidest thing VD and his fellow STD's ever said ... which is quite amazing.

As I corrected later, 1942 and 1944 January were warmer than 2011.
Interesting isn't it that the difference between 1942/1944 and 2011 is "statistically insignificant weather" in VD's demented little mind, but he also claims .2C for the LIA is enough to flash freeze plants.
