Redoing sewage handling worldwide is a major challenge.
Our sewage is contaminated with persistent organic chemicals, endocrine disruptors, pha rma ceuticals, and heavy metals. I know people working at university programs are wrestling with those issues.
By contrast, the fossil fuels coming out of the ground formed from entirely pure, naturally occurring ingredients :-)
Re Walter’s comment #201 is very confusing, he added keywords(wrong interpretation) into quotes of the IPCC report from 1990.
IPCC 1990 “A reduction in mid-latitude synoptic variability might be expected as a result of the reduction in the equator to-pole temperature gradient at low levels (Figure 5 2)”
PS, prepare for a wave of newbies who’ve just discovered the “abiotic oil” notion, thanks to some far right believers.
Rachel Maddow described this:
… when Republican Governor Pat McCrory in North Carolina needed somebody to be in charge of the most scientifically intensive of all state agencies, protecting the natural resources of North Carolina, he found somebody who apparently believes the “World Net Daily” conspiracy theory.
A conspiracy theory like this obviously has some appeal, right?
There`s a reason that some people would want to believe this. When John Skvarla first made those comments in that TV interview the day before he took office in North Carolina, the alt weekly, which is called “Indy Week” in the research triangle area in North Carolina, they reacted with some alarm to learning this was the guy who was going to be in charge of environmental issues for the state.
They listen to his interview and then they took the claims to a retired geology professor from UNC, to ask if this theory about new oil being made every day has any scientific credence whatsoever. The professor told “Indy Week”, no, the theory is, quote, in his words,
“another idea that conservatives have latched on to as a way to denying that there`s any limitation that the earth places on the way we live.”
They also noted part of the reason this theory has some appeal is if you think that the earth is not very old.
McNider and Christy present a graph showing temperature vs. model results. This graph appears similar to one presented by Roy Spencer in his written testimony before the US Senate Environment and Public Works Committee last July. Here’s the LINK to Spencer’s written comments, showing this graph as Figure 2.
Spencer claimed the graph shows Middle Troposphere data, probably the UAH TMT averaged with the RSS version of the same, both data sets based on the MSU channel 2 measurements. These data are known to include strong influence from the stratosphere in addition to that from the troposphere and was the main reason given by Spencer and Christy for the introduction of their lower troposphere (now called TLT) product back in 1992. As a result of the stratospheric influence, the MT graph shows much less warming compared to that found in other data sets for the troposphere or surface. Spencer obviously knows this, which indicates that he intended to deceive the US Senate with this presentation, IMHO.
It’s clear that McNider and Christy have perpetuated this deception by repeating the presentation of this graphical data. McNider and Christy didn’t mention that Spencer’s graph was limited to tropical latitudes between 20S and 20N, so the unaware might assume that the graph represented the entire Earth. Worse, McNider and Christy shifted the so-called “model” curve above the satellite data curve, which results in a visual impression of greater difference between the two. The WSJ op-ed was immediately pointed to by Charles Krauthammer in his latest opinion piece on the Washington Post late Thursday (The myth of ‘settled science’), spreading the disinformation to a much wider audience. The WSJ was clearly complicit in this deception, allowing the McNider and Christy piece to appear without the usual paywall that surrounds most of the WSJ site so that individuals reading Kruathammer’s commentary could link directly to the WSJ post. I suggest that these actions are just another example of the well known saying from pre-World War II Germany: “A lie repeated often enough becomes the truth”. As we are now entering another election cycle, I expect to see more of this sort of disinformation spread far and wide.
Given the ongoing concerns regarding the Keystone XL pipeline and EPA’s proposals to regulate CO2 emissions, many sectors of the US economy, such as the fossil fuel and electric power industries would likely be impacted and sending the wrong signal to the public would likely result in imprudent investments. Presenting false and deceptive information is considered a fraud in some legal situations, particularly regarding securities. For a group of individuals to do this represents conspiracy to commit fraud, which is also a crime in the US. One can only wish that these denialist be brought before a court of law to face whatever justice is applicable…

Hank @353:
It’s important to check what people claim are quotations.
This includes in scientific papers – in the days when I reviewed papers I’d check as many references as I could easily locate and a surprisingly high number were wrong. This ranged from a minor error in the author’s name or the title to claims about topics that were absent from the supposed source. I even had one author who quoted himself as finding the opposite from what his paper actually said. Some authors were spot on with all their citations, but I recall one who got 12 out of 13 references wrong (I rejected the paper – who knows how many errors were made in collecting and collating the data). If any quotation or reference is unexpected, check the original.

Gavin, that is true (re RCPs being helpful for decadal projections not so much for projections centuries hence). So are you saying that we can’t know much about the ultimate ESS for CO2 concentrations we’re seeing now? Because this is the issue – Wasdell thinks that for Hansen’s sensitivity and ESS, the levels of CO2 (and other GHGs) we have now pretty much preclude any further carbon budget to keep within the arbitrary 2C limit (except Hansen’s sensitivity allows a tiny budget). Given these more likely (?) climate sensitivities, it shouldn’t ultimately matter whether dangerous climate change occurs in 2200, 2300 or 2400 because of our actions now; surely we should care about what we leave for future generations?
In this article, study co-author Samuel Bowring talks about the end-Permian timeline study linked at #293 and #320.

Patrick Flegesays
Tony,
I fear you misunderstand me. I do agree that ESS is larger in the long term. However this is not a new finding, and does in no way negate the possibility to stay below 2°C. My beef with Wasdell is that he consistently claims to be ahead of mainstream science, yet his conclusions are often nothing to be surprised about.
But I won’t repeat, as a layman, what Gavin has already said. IPCC projections are useful for around 2100. That is correct.
I do not dismiss the risk and dangers associated with a, possibly high, ESS. However, one does need to take into account the temporal differences. Wasdell simply ignores them in order to proliferate himself.

Tony Weddle/Wili #346, #348,
Wasdell’s Bottom Line is correct, even though his approach can be questioned. We have run out of carbon budget, and are in substantial carbon debt. In the thread “If you see something, say something” (IYSSSS), #291, I use a different approach to identify the temperature target ceilings for avoiding the climate Apocalypse, and come to the above conclusion. In IYSSSS #511, I present the only self-consistent plan on the climate blogs that, if implemented, would provide a reasonable chance of avoiding the climate Apocalypse. It starts with the temperature ceilings from IYSSSS #291, and then outlines a policy/strategy as a basis for action. The actions required are not pleasant, but neither are the prospects for our survival if these harsh actions are not taken.
If your doctor says that high-dose chemo is the only way to save your life, then ‘take two asspirin and call me in the morning’ won’t do. In our case, the patient, the biosphere, is extremely ill. The plan I have presented in IYSSSS #511 is the high-dose chemo, and we have most of it available today. Like any chemo treatment, there are no guarantees; there is only maximization of chances of survival. All other ‘proposals’ I have seen presented (e.g. IYSSSS #373) are ‘take two asspirin and call me in the morning’. Their contribution to avoiding the climate Apocalypse parallels the contribution of errectile dyssfunction to good sex!

Thomassays
Gavin.
I can think of two potential objections to Wasdell.
The first is that he may be leaving out or underestimating the amount of atmospheric CO2 that will be redistribured to other earth CO2 reservoirs -particularly the oceans, and thus he is applying the sensitivity to an injection of CO2, which will significantly decline over time.
The second is just the difficulty of modeling the systems (including human inputs) over multicentury timescales.
Care to elicidate further?
[Response: That is a good point, and is indeed part of the difficulty in assessing any CO2 trajectory or level out a couple of centuries or two. – gavin]
Regarding long term outcomes, I tend to agree with flxible that even short term outcomes don’t look good but it seems to me that Wasdell is at least showing that if the international community wants to avoid 2C (because of some arbitrary idea of where dangerous climate change will kick in, agreed on years ago) then it can’t do it without removing atmospheric greenhouse gases and so any notion that some emissions reduction agreement can do the trick are delusions. If only the next 86 years are important, however, then a different argument ensues.
Tony, the climate scientists will be delighted to run multiple scenarios over longer time spans. A model generates a range of possibilities. Each run takes a lot of computer time and money.
You’ve probably heard the story about planning large computation-intensive projects: you can either
1) buy today’s hardware, build a computer center, and run for five years, with a large staff, or
2) take the same amount of money, go to Bermuda for four years to party, then spend what’s left over on a fast computer and do the same project in one year on your desktop.
Dave Peterssays
freemike (# 372)– Your query raises two rather distinct topics: a) the “pause,” and b) the “models running cool”. Both have received much attention, if you are not in deep yet, with the development of your interest. I have been a devout warmist for decades, but with long gaps in my attention to the literature. In these past couple years, I am struck by the greatly enhanced attention being devoted to a far more thoroughly instrumented Pacific Ocean. I hope that we may well be nearing the brink of having within humanity’s grasp, not only strong inferences about the recent, relative decadal reduction in the rate of surface warming (compared with the final quarter of Century 20), but also with a more compelling story about the true pause which stretched across the middle of that century. Many keyposts at RC across the past year address a declining proportion of the radiative imbalance which may be flowing to the surface and air, compared with a Pacific which has been more prone to ENSO behavior characterized by fewer and less intense El Ninos, or a protracted quasi-La Nina bias. To which the minimalists respond, “yeah, and the dog ate my homework”. Or, “well, if the Pacific sucks up the excess energy, it is thereby no big problem”. These are subjects of deep technical complexity, at the edges of what an immense expenditure of extraordinary mental talent, has yet to securely win over to the known realm.
The first of the concerns you raise however, results from an altogether different source. Namely, the “pause” arises from a deliberate and egregious distortion of elementary statistical methods long since known and routinely practiced, for interpreting intrinsically noisy data, such as that exhibited by our thermometer record. This false claim then, is endlessly repeated. And that practice cannot be remedied by esoteric science, but rather by a vigilant citizenship which talks common sense rejoinders to the common man.
Commenter Swanson above (# 355) mentions a few of the usual suspects: Roy Spencer, Charles Krauthammer, and Paul Gigot at the WSJ editorial page. I have made a practice of frequently challenging their references to the “pause” wherever and whenever I encounter them, and will dig up a recent example, momentarily. I think it might be helpful if we members of the choir could share, critique, encourage and improve upon each others efforts along such lines.
Dave Peterssays
freemike (# 372) -– Here is my retort to the “pause claim” made by Fred Singer, which I encountered somewhere on Real Clear Politics within the past few months:
In the single year beginning September 1, 1997, and ending on August 31, 1998, the Pacific Ocean disgorged a huge amount of stored-up energy. The heat from that unprecedented El Nino, possibly assisted by far smaller variations elsewhere, was sufficient to elevate the temperature of the world’s near surface air by 0.55 Fahrenheit degrees, compared with the preceding twelve months. [from HadCRUT4]
We are now confident that the world cooled for many centuries, before it assuredly stopped cooling, and began warming, several years into the 20th century. In the 104 years which have elapsed between 2011 (our latest central year of the 5-yr. running average), and 1907 (the year, very broadly averaged, when multi-century cooling bottomed, and Global Warming began), the annual incremental warming has averaged 1.57 hundredths degree F. [from GISS]
In those twelve months therefore, we added 35 year’s worth of normal heat gain [0.546 / 0.0157 = 34.7]. When Mr. Singer (or similarly, the likes of Charles Krauthammer, Paul Gigot, John Stossel, or Michael Barone) steps upon that needle point, to assert that the Earth’s behavior since 1998 has exhibited no warming, one might fairly respond: why don’t you get back to us on that in August of, say, 2032?

Thoughts on Abrupt Climate Change, As In 30 Years, not 100
— February 20, 2014
University of Colorado Professor Jim White offers examples in the individual and corporate sectors of impacts that could be felt as a result of abrupt climate change. (Video)
…
… White explains in a new two-minute Yale Forum video interview that he was approached by a supplier of major air conditioning systems for companies on the scale of Microsoft and Google with the question, “What’s the average high temperatures going to be 40 years from now.”
He explained that customers want to write-off such capital investments over four decades, but if they build for average high temperatures reached over a shorter period … trouble city.
“They need to buy oversized for today so they can adapt to tomorrow.”
Independent videographer Peter Sinclair recorded White, along with a number of other climate scientists during the December meeting of the American Geographical Union in San Francisco, Ca. White was the chair of a recent National Research Council report on abrupt climate change.
(Actually, they need to build different buildings, not over-buy A/C.
I recently heard an architect comment (KQED’s radio locally) that how nuts it is to be build thick highly insulated cool-white or green-planted-roofs on buildings in Sacramento — that he could accomplish the same result by having big trees shading ordinary shingled roofs.)

Flxible wrote “Not sure why folks would be concerned about the climate in 22 or 2300 when the climate today indicates the immediate future, even the lifetimes of the oldtimers here, may be untenable soon.”
Fast and Slow Responses to Global Warming: Sea Surface Temperature and Precipitation Patterns The deep ocean warming retards the surface warming in the fast response but turns into a forcing for the slow response. As a result, the fast and slow responses are nearly opposite to each other in spatial pattern, especially over the subpolar North Atlantic/Southern Ocean regions of the deep-water/bottom-water formation, and in the interhemispheric SST gradient between the southern and northern subtropics. Wind–evaporation–SST feedback is an additional mechanism for the SST pattern formation in the tropics.
Analyses of phase 5 of the Coupled Model Intercomparison Project (CMIP5) multimodel ensemble of global warming simulations confirm the validity of the diagnostic method that separates the fast and slow responses. Tropical annual rainfall change follows the SST warming pattern in both the fast and slow responses in CMIP5, increasing where the SST increase exceeds the tropical mean warming. http://tinyurl.com/lczv53z

Peter Brunson: “What time frame do you associate with soon?”
“… the immediate future, even the lifetimes of the oldtimers here …” …. isn’t clear?
As one of the ‘old timers’, I’m not too concerned with the climate, globally or locally, 80-90 years from now, why would I be interested in it 1-200 years hence? Why would you be interested in it? Concern for a hypothetical ’10th’ generation? What concerns me is the immediate future, which isn’t looking too rosy, particularly for any major change to “BAU”. Speculation about the far future is pointless when we have such an poor understanding of the present, particularly concerning the details of climate, but what we should know is that your immediate children [if you have such, I don’t], will not find the planet as comfortable as it has been. OTOH, this is a climate site, so speculation about unknowns isn’t entirely out of place. :)

#385 – Dave Peters – Yeah, that old “pause” thingy. Funny thing, those folks who rant about the so-called “pause” don’t want to talk about the low solar activity during the last solar cycle, even though a few years ago these same guys probably claimed that the world was heading into another Maunder Minimum cold period. Also, not one of them wants to talk about the massive increase in coal burning in China and India over the past 20 years, the result being a major increase in SO2 emissions. Also, the rapid economic growth has also resulted in large increases in diesel emissions, thus more “black carbon” particulate air pollution from both countries. That Asian Brown Cloud keeps growing larger each year, which one might expect to have an impact on weather, that is, if one were interested in a truthful presentation.

“If we cannot distill complex science into plain English, the failure is ours.”–Dr. Ben Santer, about a half hour ago.
As for not building light, well-insulated roofs because they can be shaded by large trees,
That’s true, but short-sighted. What happens when drought, flood, violent wind, ice storms, salt, or a disease kills the tree large tree? What about new houses that won’t be shaded by just-planted trees for a decade or three? What about using the roof-top for solar panels?
It doesn’t seem stupid to me to have a light, well-insulated roof at all.
Any opinions whether they have made a mistake in the analysis by using the SST data model from Hadley rather than that of NOAA? To me, it looks like HadSST has been overly tampered with by questionable correction algorithms, especially post WWII.
So, after all that work, all they have done is recreate HadCRUT4. I suspect that they would have recreated GISS GISTEMP loti if they replaced HadSST with NOAA’s ERSST.
GISS is still the BEST, imo.

What “same result”?
A recent study found that the results of white roofs and green-planted roofs are quite different:
Looking strictly at the economic costs and benefits of three different roof types — black, white and “green” (or vegetated) — Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span …
A green roof, often called vegetated roofs or rooftop gardens, has become an increasingly popular choice for aesthetic and environmental reasons … For example rooftop gardens provide stormwater management, an appreciable benefit in cities with sewage overflow issues, while helping to cool the roof’s surface as well as the air …
However, unlike white roofs, green roofs do not offset climate change. White roofs are more reflective than green roofs, reflecting roughly three times more sunlight back into the atmosphere and therefore absorbing less sunlight at earth’s surface. By absorbing less sunlight than either green or black roofs, white roofs offset a portion of the warming effect from greenhouse gas emissions …
Both white and green roofs do a good job at cooling the building and cooling the air in the city, but white roofs are three times more effective at countering climate change than green roofs.
I would ask that architect on the radio where he would plant those “big trees” that can shade the entire roof of a commercial building, in the middle of a densely built-up urban environment?
And how long would it take those trees to grow big enough to shade the entire roof of a commercial building? Perhaps it would take as long to grow them as the entire 50-year life span of an inexpensive highly-reflective white roof that could be installed in a matter of days?
I’m all for planting more trees. LOTS more trees, including in urban areas wherever possible. But it seems there are cheaper and faster ways to address the problem of black roofs (which the Berkeley Lab study found post a significant public health risk — “In Chicago’s July 1995 heat wave a major risk factor in mortality was living on the top floor of a building with a black roof”).

I even had one author who quoted himself as finding the opposite from what his paper actually said. Some authors were spot on with all their citations, but I recall one who got 12 out of 13 references wrong (I rejected the paper – who knows how many errors were made in collecting and collating the data). If any quotation or reference is unexpected, check the original.

Gavin, that is true (re RCPs being helpful for decadal projections not so much for projections centuries hence). So are you saying that we can’t know much about the ultimate ESS for CO2 concentrations we’re seeing now? Because this is the issue – Wasdell thinks that for Hansen’s sensitivity and ESS, the levels of CO2 (and other GHGs) we have now pretty much preclude any further carbon budget to keep within the arbitrary 2C limit (except Hansen’s sensitivity allows a tiny budget). Given these more likely (?) climate sensitivities, it shouldn’t ultimately matter whether dangerous climate change occurs in 2200, 2300 or 2400 because of our actions now; surely we should care about what we leave for future generations?

In this article, study co-author Samuel Bowring talks about the end-Permian timeline study linked at #293 and #320. The article says the next step is to see how the timeline of the extinctions compares to the timeline of the Siberian Traps eruptions. Geochronologist Bowring says, “We are slowly spiraling in on the truth.”

Correction: Bowring says, ““You can think of it as slowly spiraling in toward the truth.”
Patrick Flege says
Tony,
I fear you misunderstand me. I do agree that ESS is larger in the long term. However this is not a new finding, and does in no way negate the possibility to stay below 2°C. My beef with Wasdell is that he consistently claims to be ahead of mainstream science, yet his conclusions are often nothing to be surprised about.
But I won’t repeat, as a layman, what Gavin has already said. IPCC projections are useful for around 2100. That is correct.
I do not dismiss the risk and dangers associated with a, possibly high, ESS. However, one does need to take into account the temporal differences. Wasdell simply ignores them in order to proliferate himself.
Tony Weddle says

He gave the prepper bloggers there a decent explanation of the problems with Wasdell, I’d agree.
DIOGENES says
Tony Weddle/Wili #346, #348,
Wasdell’s Bottom Line is correct, even though his approach can be questioned. We have run out of carbon budget, and are in substantial carbon debt. In the thread “If you see something, say something” (IYSSSS), #291, I use a different approach to identify the temperature target ceilings for avoiding the climate Apocalypse, and come to the above conclusion. In IYSSSS #511, I present the only self-consistent plan on the climate blogs that, if implemented, would provide a reasonable chance of avoiding the climate Apocalypse. It starts with the temperature ceilings from IYSSSS #291, and then outlines a policy/strategy as a basis for action. The actions required are not pleasant, but neither are the prospects for our survival if these harsh actions are not taken.
If your doctor says that high-dose chemo is the only way to save your life, then ‘take two asspirin and call me in the morning’ won’t do. In our case, the patient, the biosphere, is extremely ill. The plan I have presented in IYSSSS #511 is the high-dose chemo, and we have most of it available today. Like any chemo treatment, there are no guarantees; there is only maximization of chances of survival. All other ‘proposals’ I have seen presented (e.g. IYSSSS #373) are ‘take two asspirin and call me in the morning’. Their contribution to avoiding the climate Apocalypse parallels the contribution of errectile dyssfunction to good sex!

Tony, re not knowing much with confidence about the course of events past 2100 —
Amateur perspective: do you read GRL? Browsing the abstracts every week turns up new possible events with uncertain outcomes about and for climate.
You can rule out slow calm beneficial climate changes, it seems.
flxible says
Not sure why folks would be concerned about the climate in 22 or 2300 when the climate today indicates the immediate future, even the lifetimes of the oldtimers here, may be untenable soon. We do know things need to change, but apparently we’re going to await the changes that “natural variations” force upon us. Maybe chisel an apology on a stone [that’d be hard copy] to leave for your great-grandchildren in case digital or paper messages don’t weather the storms. :)
Thomas says
Gavin.
I can think of two potential objections to Wasdell.
The first is that he may be leaving out or underestimating the amount of atmospheric CO2 that will be redistribured to other earth CO2 reservoirs -particularly the oceans, and thus he is applying the sensitivity to an injection of CO2, which will significantly decline over time.
The second is just the difficulty of modeling the systems (including human inputs) over multicentury timescales.
Care to elicidate further?
[Response: That is a good point, and is indeed part of the difficulty in assessing any CO2 trajectory or level out a couple of centuries or two. – gavin]
Tony Weddle says
Hank, thanks for the tip of scanning GRL. I will.
Regarding long term outcomes, I tend to agree with flxible that even short term outcomes don’t look good but it seems to me that Wasdell is at least showing that if the international community wants to avoid 2C (because of some arbitrary idea of where dangerous climate change will kick in, agreed on years ago) then it can’t do it without removing atmospheric greenhouse gases and so any notion that some emissions reduction agreement can do the trick are delusions. If only the next 86 years are important, however, then a different argument ensues.

Hank Roberts says

Nobody has made any such argument.
Tony, the climate scientists will be delighted to run multiple scenarios over longer time spans. A model generates a range of possibilities. Each run takes a lot of computer time and money.
You’ve probably heard the story about planning large computation-intensive projects: you can either
1) buy today’s hardware, build a computer center, and run for five years, with a large staff, or
2) take the same amount of money, go to Bermuda for four years to party, then spend what’s left over on a fast computer and do the same project in one year on your desktop.
Dave Peters says
freemike (# 372)– Your query raises two rather distinct topics: a) the “pause,” and b) the “models running cool”. Both have received much attention, if you are not in deep yet, with the development of your interest. I have been a devout warmist for decades, but with long gaps in my attention to the literature. In these past couple years, I am struck by the greatly enhanced attention being devoted to a far more thoroughly instrumented Pacific Ocean. I hope that we may well be nearing the brink of having within humanity’s grasp, not only strong inferences about the recent, relative decadal reduction in the rate of surface warming (compared with the final quarter of Century 20), but also with a more compelling story about the true pause which stretched across the middle of that century. Many keyposts at RC across the past year address a declining proportion of the radiative imbalance which may be flowing to the surface and air, compared with a Pacific which has been more prone to ENSO behavior characterized by fewer and less intense El Ninos, or a protracted quasi-La Nina bias. To which the minimalists respond, “yeah, and the dog ate my homework”. Or, “well, if the Pacific sucks up the excess energy, it is thereby no big problem”. These are subjects of deep technical complexity, at the edges of what an immense expenditure of extraordinary mental talent, has yet to securely win over to the known realm.
The first of the concerns you raise however, results from an altogether different source. Namely, the “pause” arises from a deliberate and egregious distortion of elementary statistical methods long since known and routinely practiced, for interpreting intrinsically noisy data, such as that exhibited by our thermometer record. This false claim then, is endlessly repeated. And that practice cannot be remedied by esoteric science, but rather by a vigilant citizenship which talks common sense rejoinders to the common man.
Commenter Swanson above (# 355) mentions a few of the usual suspects: Roy Spencer, Charles Krauthammer, and Paul Gigot at the WSJ editorial page. I have made a practice of frequently challenging their references to the “pause” wherever and whenever I encounter them, and will dig up a recent example, momentarily. I think it might be helpful if we members of the choir could share, critique, encourage and improve upon each others efforts along such lines.
Dave Peters says
freemike (# 372) -– Here is my retort to the “pause claim” made by Fred Singer, which I encountered somewhere on Real Clear Politics within the past few months:
In the single year beginning September 1, 1997, and ending on August 31, 1998, the Pacific Ocean disgorged a huge amount of stored-up energy. The heat from that unprecedented El Nino, possibly assisted by far smaller variations elsewhere, was sufficient to elevate the temperature of the world’s near surface air by 0.55 Fahrenheit degrees, compared with the preceding twelve months. [from HadCRUT4]
We are now confident that the world cooled for many centuries, before it assuredly stopped cooling, and began warming, several years into the 20th century. In the 104 years which have elapsed between 2011 (our latest central year of the 5-yr. running average), and 1907 (the year, very broadly averaged, when multi-century cooling bottomed, and Global Warming began), the annual incremental warming has averaged 1.57 hundredths degree F. [from GISS]
In those twelve months therefore, we added 35 year’s worth of normal heat gain [0.546 / 0.0157 = 34.7]. When Mr. Singer (or similarly, the likes of Charles Krauthammer, Paul Gigot, John Stossel, or Michael Barone) steps upon that needle point, to assert that the Earth’s behavior since 1998 has exhibited no warming, one might fairly respond: why don’t you get back to us on that in August of, say, 2032?

Thoughts on Abrupt Climate Change, As In 30 Years, not 100
— February 20, 2014
(Actually, they need to build different buildings, not over-buy A/C.
I recently heard an architect comment (KQED’s radio locally) that how nuts it is to be build thick highly insulated cool-white or green-planted-roofs on buildings in Sacramento — that he could accomplish the same result by having big trees shading ordinary shingled roofs.)
Peter Brunson says

prokaryotes says
@Hank, #387
flxible says
Peter Brunson: “What time frame do you associate with soon?”
“… the immediate future, even the lifetimes of the oldtimers here …” …. isn’t clear?
As one of the ‘old timers’, I’m not too concerned with the climate, globally or locally, 80-90 years from now, why would I be interested in it 1-200 years hence? Why would you be interested in it? Concern for a hypothetical ’10th’ generation? What concerns me is the immediate future, which isn’t looking too rosy, particularly for any major change to “BAU”. Speculation about the far future is pointless when we have such an poor understanding of the present, particularly concerning the details of climate, but what we should know is that your immediate children [if you have such, I don’t], will not find the planet as comfortable as it has been. OTOH, this is a climate site, so speculation about unknowns isn’t entirely out of place. :)

Eric Swanson says
#385 – Dave Peters – Yeah, that old “pause” thingy. Funny thing, those folks who rant about the so-called “pause” don’t want to talk about the low solar activity during the last solar cycle, even though a few years ago these same guys probably claimed that the world was heading into another Maunder Minimum cold period. Also, not one of them wants to talk about the massive increase in coal burning in China and India over the past 20 years, the result being a major increase in SO2 emissions. Also, the rapid economic growth has also resulted in large increases in diesel emissions, thus more “black carbon” particulate air pollution from both countries. That Asian Brown Cloud keeps growing larger each year, which one might expect to have an impact on weather, that is, if one were interested in a truthful presentation.

As for not building light, well-insulated roofs because they can be shaded by large trees,
That’s true, but short-sighted. What happens when drought, flood, violent wind, ice storms, salt, or a disease kills the tree large tree? What about new houses that won’t be shaded by just-planted trees for a decade or three? What about using the roof-top for solar panels?
It doesn’t seem stupid to me to have a light, well-insulated roof at all.

The Berkeley BEST Land+Ocean temperature series is available to supplement the Land-only previous analysis.

Any opinions whether they have made a mistake in the analysis by using the SST data model from Hadley rather than that of NOAA? To me, it looks like HadSST has been overly tampered with by questionable correction algorithms, especially post WWII.
So, after all that work, all they have done is recreate HadCRUT4. I suspect that they would have recreated GISS GISTEMP loti if they replaced HadSST with NOAA’s ERSST.
GISS is still the BEST, imo.

Hank Roberts wrote: “I recently heard an architect comment (KQED’s radio locally) that how nuts it is to be build thick highly insulated cool-white or green-planted-roofs on buildings in Sacramento — that he could accomplish the same result by having big trees shading ordinary shingled roofs.”
What “same result”?
A recent study found that the results of white roofs and green-planted roofs are quite different:
I would ask that architect on the radio where he would plant those “big trees” that can shade the entire roof of a commercial building, in the middle of a densely built-up urban environment?
And how long would it take those trees to grow big enough to shade the entire roof of a commercial building? Perhaps it would take as long to grow them as the entire 50-year life span of an inexpensive highly-reflective white roof that could be installed in a matter of days?
I’m all for planting more trees. LOTS more trees, including in urban areas wherever possible. But it seems there are cheaper and faster ways to address the problem of black roofs (which the Berkeley Lab study found post a significant public health risk — “In Chicago’s July 1995 heat wave a major risk factor in mortality was living on the top floor of a building with a black roof”).
