No climate conspiracy: NOAA temperature adjustments bring data closer to pristine
The graph below shows two interesting things:
- Nearby weather stations usually have an almost identical temperature trend, which is very useful when homogenizing temperature records.
- The Norwegian meteorological institute (DNMI) has obviously done a good job when adjusting the Oslo record to remove the effect from UHI. If not, it would show a stronger warming trend than the two other stations.
Færder is a lighthouse located in the outer Oslofjord, about 100 km south of Oslo. Nesbyen is a village in the Hallingdalen valley, about 120 km northwest of Oslo. It’s known for its high summer temperatures, but has much colder winters than Oslo and Færder.
I considered including Stockholm in Sweden too (about 400 km east of Oslo), but it would make the graph seem quite cluttered since Stockholm’s absolute temperature and trend is almost identical to Oslo’s. -
mancan18 at 08:04 AM on 13 February 2016The gutting of CSIRO climate change research is a big mistake
Tom Curtis, thanks for your extensive comments. They are illuminating as your comments always are. I was not aware of how the CSIRO is managed. I am well aware that Labor, as well as the LNP, do not always see science as a funding priority and are happy to make funding cuts whenever they feel it is necessary. Personally, I think that independent scientific research should be funded as a fixed percentage of GDP and it should be related to the CPI to guarantee that funding. What level that the funding should be is, of course, an open question. However, it should be at least comparable to our OECD partners. Also, I don't think that independent science research can be easily privatised in Australia without the integrity of the science being compromised at times. This is because Australia does not have a history of the extensive philanthropic funding of science that some other countries have. Nor does it have the extensive high tech arms industry of our allies which attracts some of their Government funded scientific research. This is and has always been the problem of properly funding science in Australia. Certain appropriate funding would ensure that our best minds are attracted to science in Australia, remain in Australia and are gainfully employed, after all, science, while the short term dividend is not always clear, is the great multiplier that has driven the evolution of our high tech modern society and is needed to protect it.
Ryland, accounting and scientific reality are always fair for comparison. It is the money provided that determines the science that is studied. The scientific reality will stay the same whether it is studied or not. It's just that we may not know what it is. For our viability into the future, it is important for us to know what that scientific reality is. Ultimately, the money for science is usually allocated by people who have qualifications in business administration, economics, finance, the law or in marketing. While our scientific organisations are normally managed by people with a scientific background, not many outside these scientific organisations, such as our politicians and Treasury, who are the ultimate arbiters of funding science, do not have a scientific background and necessarily understand its needs and nature. So when they decide on a funding cut, it is the managers of scientific organisations who have to curtail scientific programs, not the people who have decided to cut funding. Not many people go into science for the money. They go into it because they are curious and just want to know what is happening and how it happens. If they happen to make a lot of money out of it, is merely coincidental. Science does not always pay a short term dividend in the economic sense, but it does tend to pay a huge long term dividend from which the whole of society benefits. Climate science is about the long term dividend of protecting our world and should be properly funded. It is not about either-or it is about doing both.

dagold at 05:04 AM on 13 February 2016The new age of climate exploration
Thank you for the article. I even went to the "optomist/pessimist" cite that you linked. And....this may put me in the pessimist camp but - as far as I am aware there are abosultely none - zero - financial sanctions or penalties connected to NOT honoring the commitments made in Paris. Without agreed upon and 'hammered out in iron' economic penalties for nations opting out, I see this entire 'accord' as simply fantasy. I dearly hope that events on the ground prove me wrong. If they do, I shall be quite surprised. (see, for example, the U.S. Supreme court just blocking the one and only climate policy with some actual teeth that Obama put out - and the obstructionists in Congress and the courts are not going away anytime soon).

Daffodils in bloom, the warmest ever December: how worrying is the world’s strange weather?
NecktopPC - A Guilt by Association fallacy (perhaps better described as Poisoning the Well) is your response to Abu-Asab et al 2001? That's no argument at all. And linking only the current bloom schedule is a red herring - the opening post is about climate trends.
If you have genuine issues with that Abu-Asad et al's methodology (which is quite simple, really) or their conclusions (difficult to see how, simple statistics), preferrably supported by some published literature, great, it might be interesting to discuss. The same goes for growth regions published by the USDA - I'm sure farmers would love to avoid changing crops due to shifting hardiness zones, and would eagerly await actual evidence for climate stability.
However, throwing out nothing but logical fallacies seems to indicate you have no actual evidence backing your posts.

Tom Curtis at 18:37 PM on 12 February 2016The gutting of CSIRO climate change research is a big mistake
Further information, and comments.
First, Larry Marshall clarified the restructure on Monday 8th here. Amongst other things he said:
"In our Oceans and Atmosphere business we have about 420 staff, not 140 as reported by some media, and after these changes we expect to have about 355, contrary to media reports. We asked business unit leaders to focus their operational plans on growth, and growth within finite resources will always initially lead to making choices about what to exit. However, as painful as any redundancy is, for the majority of the 5,200 CSIRO employees there will be no change to their current circumstances as a result of these plans, and we will also recruit new people with new skills."
This, however, seems like misdirection to me. Specifically, the 100 full time positions lost from the Oceans and Atmosphere section will be lost from just two out of five units. Both are heavilly focussed on climate research. The question is, how many staff are their in the two units that will sustain the losses? Larry Marshall does not answer, and the answer it probably 140. Marshall merely distracts us by inflating the denominator.
Marshall goes on:
"The second area of correction is our ability to support climate measurement in Australia. Cape Grim and RV Investigator are not under threat from these changes. The Cape Grim air pollution monitoring station which is a source of much of our greenhouse gas information will continue to be that source. Our climate models have long been and will continue to be available to any researcher and we will work with our stakeholders to develop a transition plan to achieve this. The RV Investigator, operated by CSIRO for scientists from Australia and around the world as a state of the art research facility will continue to operate scientific voyages, gathering data every day at sea. We also have an air archive which is a resource available to any researcher to investigate air changes over time. We will also continue our contribution to the international Argo floats program which provides thousands of datapoints for temperature and salinity of our oceans; and we’ll be investing more in autonomous vehicles, using innovation to collect more data than ever before."
While happy to hear that Cape Grim will survive, I am less than sanguine about the other reassurances. RV Investigator is a multi-function research vessel and can continue its voyages very easilly without any research on climate (focussing instead on ecology, for instance). Nor does a continued contribution to the Argo floats program assure us that the level of contribution will remain the same. Finally, the phrasing of the assurance regarding the climate model suggests that it will not be used by CSIRO researchers, merely that it will be available to others (of which more later). More important, it contains no assurance of the continued development and testing of the model, without which it will be obsolete in 4-5 years.
Ryland above reffers us to the Senate Estimates hearings, for which (unfortunately) a transcript is not yet available. The SMH, however, reported on the hearings. From them we learn that:
1) An original document planning this restructuring indicated the need for the loss of only 35 positions from Ocean and Atmosphere, which can reasonably be taken as the number of cuts necessary to impliment the restructure without loss of significant, relevant capacity. Apparently the increase from 35 to 100 positions was a top down position made without familiarity with the research being cut.
'"Those numbers of 100 are very round," said one senior researcher, who had watched the live stream of the hearing and whose work may face the chop. "What was the rationale for coming up with them? We still don't know."'
2) The board was told of the level of cuts involved in the restructure just two days before the public announcement. From that it is clear that this was not a decision made in consultation with the board, and ergo also not a decision whose rational has been tested by independent scrutiny.
3) The executives making the decision had not adequately informed themselves of the details of the operations and research they were cutting. This is evident in their having made several errors about that research in responding to Senate Estimates. In particular:
"For instance, they initially said the key Australian Community Climate and Earth System Simulator (ACCESS) model jointly worked on by the Bureau of Meteorology and CSIRO was "open-sourced", allowing for wide-ranging contributions that might offer the opportunity for savings."
A belief that the software was open access may well have contributed to a belief that the CSIRO "climate models have long been and will continue to be available to any researcher" even while cutting the staff that operate those models (see Marshall's clarrification, and discussion above).
This is fairly crucial in that Senate Estimates is the only indepedant scrutiny of the suitability of the restructure, and for the exectives to not have the basic facts underlying the restructure at their fingertips for Senate Estimates shows the numbers were chosen independent of an actual analysis of the number of staff needed to be retained for the capability Marshall claims will be maintained. His clarrification is therefore revealed more as a statement of faith than something of which he can genuinely reassure us based on analysis. Worse, his faith inflated by a factor of three the number of cuts an actual analysis showed to be appropriate.

ryland at 13:54 PM on 12 February 2016The gutting of CSIRO climate change research is a big mistake
mancan18@18 Your comment "It seems that the economic rationalist LNP Australian Government wants to embrace fund cutting policies that reduce the level of scientific expertise in Australia while at the same time beating the mantra of innovation." The cuts to the CSIRO were under the aegis of Tony Abbott. The "mantra of innovation" is from Turnbull.
Compare like with like?
Your obsdervation "But then again, it's all about the accounting, not the scientific reality."is equally applicable to the personnel changes at CSIRO. However at today's Senate hearing the CEO of CSIRO said ""that CSIRO would ensure "vital" modelling and monitoring of climate change would continue.".
Is all this angst premature?

Tom Curtis at 10:53 AM on 12 February 2016The gutting of CSIRO climate change research is a big mistake
On the same topic, funglestrumpet @16, it is very dubious that the former British Chancellor of the Exchequer has much direct influence on the Treasury Department of the Commonwealth of Australia, or the Treasurer in the Australian Government. Given the details @19, the idea that this redeployment of CSIRO resources results from the undue influence of Lawson in UK politics is not credible.
For deniers as for supporters of science, this came as a bolt of lightning out of the blue. The only difference is that they while they celebrate the loss of fundamental research on climate, supporters of science regret it.

-
Tom Curtis at 10:44 AM on 12 February 2016The gutting of CSIRO climate change research is a big mistake
mancan @18, your comment is excellent all round. However, it does seem to attribute the current changes to the CSIRO to the government.
As it happen, the chief executive of the CSIRO is not appointed directly by government, but by the board of the CSIRO. The Chairman of the Board at the time this was done was, Simon McKeon, was appointed by a Labor government. He raised ire among deniers by his attitude towards Climate Change:
"Despite admitting he has "no scientific pedigree", Mr McKeon says he wants to see the issue of climate change elevated to the top of the political and public agenda.
"We may not have all the answers to what is occurring, we may not have certainly all the solutions to how to fix it," he said.
"But the point is, why wouldn't one take out very strong insurance to at least do what we can to future-proof our well-being? I think it's a no-brainer.""
Even today, nearly half of the board are Labor appointees, and at the time of appointment of Larry Marshall, the majority would have been.
As tempting as it might be to suppose this is an act of the government, it is not. It is the act of an independent manager of the CSIRO, of whom there is no reason to think that he is a denier or influenced by deniers.
There is a contradiction between Prime Minister Turnbull's supposed commitment to innovation and his not reversing Abbott's cuts to the CSIRO - but this decision is not a direct reflection of that contradiction.

mancan18 at 09:32 AM on 12 February 2016The gutting of CSIRO climate change research is a big mistake
Because of these cuts, there will also be a loss of corporate knowledge at the CSIRO. This loss of knowledge and expertise is, justifiably, of concern. Science is a collegiate profession which grows through interaction between scientists, not from scientists just working independent of each other. Change and renewal in collegiate professions should be a gradual process that occurs from the bottom upwards, not from the top downwards otherwise there will be a loss of corporate knowledge. New people coming to the organisation bring new knowledge and those already there bring experience that can best utilise that new knowledge. The modern management practices that have evolved in an age of economic rationalism and neoconservative politics don't seem to account for the nature of collegiate professions. I am a retired educator and have seen the impact and loss of expertise that can occur from gutting from the top rather than renewing from the bottom.
Another factor is that not all the climate scientists who have been at the forefront of climate reasearch in Australia can be necessarily redeployed elsewhere. Their expertise may not easily translate to a different discipline or emphasis. While the CSIRO should not be a welfare agency for scientists who no longer have experise that is relevant to their research, it is not as if the nature of the climate system and the Earth as a global ecosystem is fully understood yet. While the debate has been essentially won in scientific circles, it is not as if the debate has been fully won with the wider community. Reducing the climate science expertise of the CSIRO may also make it easier for climate deniers to continue to cast doubt because as the integrity of independent science is being undermined by reduced funding, corporate funding of vested interest "science" will most likely rise in response to a wider public acceptance of the science. After all funding climate science denial is more a delaying tactic to continue to exploit, what is now, a dwindling dirty resource for a technologically outdated industry.
Also, it seems strange that the Australia Government is happy to fund laboratories to assess whether products meet Australian safety and health standards, even though there are many other assessment laboratories in other countries. I would have thought that studying the climate would be a similar, unless of course the Government doesn't think there are safety and health issues related to a changing climate.
It seems that the economic rationalist LNP Australian Government wants to embrace fund cutting policies that reduce the level of scientific expertise in Australia while at the same time beating the mantra of innovation. It's a bit like their Direct Action climate change policy, funding to reduce emissions while allowing increased emissions. But then again, it's all about the accounting, not the scientific reality.

The current thinking is that the PETM is not likely an orbitally forced event even if some of the subsequent hyperthermals may have been.
Yes, and I should have been clear about this. I mentioned DeConto because I'd implied that the PETM wasn't orbitally triggered and didn't want to create the impression that nobody had argued otherwise.

Daffodils in bloom, the warmest ever December: how worrying is the world’s strange weather?
NecktopPC - Yes, there is yearly and even decadal variation in flowering times everywhere. However, there is also a distinct and statistically significant trend in earlier and earlier blooming, in pole-ward shifting of plant hardiness zones, and claiming it's all due to short term variation is quite frankly nonsense.
Just from my region, see Abu-Asab et al 2001, "Earlier plant flowering in spring as a response to global warming in the Washington, DC, area", noting that those times "...show a significant advance of 2.4 days over a 30-year period [...] Advances of first-flowering in these 89 species are directly correlated with local increase in minimum temperature."
Also see Chung et al 2011, "Predicting the Timing of Cherry Blossoms in Washington, DC and Mid-Atlantic States in Response to Climate Change", noting that "Our results indicate that PBD [Peak Bloom Dates] at the Tidal Basin are likely to be accelerated by an average of five days by 2050 and 10 days by 2080 for these cultivars under a mid-range (A1B) emissions scenario."
The times, and the plant zones, they are a-changing. Handwaving like yours doesn't change that.

howardlee at 06:43 AM on 12 February 2016Onset of Eocene Warming Event took 3-4 millennia (so what we’re doing is unprecedented in 66 million years)
To be clear Both Zeebe's and the Kirtland Turner & Ridgwell study are talking about the initial warming of the PETM and the initial pulse of carbon that caused it.
The current thinking is that the PETM is not likely an orbitally forced event even if some of the subsequent hyperthermals may have been. I covered that in an article in 2014 here.
There's very strong evidence for intense volcanic activity associated with the North Atlantic Igneous Province (yes yet another Large Igneous Province associated with a warming event) ocurring at exactly the time of the PETM, See:
Zircon dating ties NE Atlantic sill emplacement to initial Eocene global warming
These papers are also relevant:

Development of intra-basaltic lava-field drainage systems within the Faroe–Shetland Basin
Diachronous sub-volcanic intrusion along deep-water margins: insights from the Irish Rockall Basin
Kimberlite eruptions as triggers for early Cenozoic hyperthermals
However, from an isotope signature point of view the methane hydrate source works according to Zeebe, who told me: " I’m still convinced that this methane hydrate hypothesis is working very well in terms of total amount of carbon and in terms of the isotopic signature that we see. I think there is evidence that there could be mud volcanoes in the North Atlantic that could have contributed exactly to methane release during the PETM."
Whereas Ridgwell told me: " It seems it’s all around the time of a lot of enhanced volcanism going on in the North Atlantic and people have suggested, and I’m coming around to the importance of this, of a particular episode of quite extensive volcanism happening in the North Atlantic just at the time of the PETM. So it seems that maybe [the PETM] is a little bit like some of these older events."

-
BBD at 05:33 AM on 12 February 2016Onset of Eocene Warming Event took 3-4 millennia (so what we’re doing is unprecedented in 66 million years)
I should have added that there is a hypothesis (DeConto et al. 2010) that orbital forcing triggered the PETM. There is an SkS article about the DeConto study here.

BBD at 05:28 AM on 12 February 2016Onset of Eocene Warming Event took 3-4 millennia (so what we’re doing is unprecedented in 66 million years)
#1 SteveFunk
I think it's true that CO2 (and CH4) are considered to be feedbacks to orbitally-forced warming (Milankovitch forcing) that is widely regarded as the trigger for Pleistocene deglaciations. In the case of the PETM and other Cenozoic hyperthermals, the CO2 may be the initial cause, so it would be treated as a forcing rather than a feedback. If there was a subsequent large release of CH4 from clathrates, it would be reasonable to treat that as a feedback to the original increase in CO2 forcing.
-
SteveFunk at 04:11 AM on 12 February 2016Onset of Eocene Warming Event took 3-4 millennia (so what we’re doing is unprecedented in 66 million years)
What I have always read is that previous warmings were originally caused by other factors but were amplified over time by CO2 as a feedback mechanism. So Zeebe's study does not appear to answer the question of how long it took to establish the original warming or what the magnitude of the original warming was relative to the CO2 feedback.

John Hartz at 01:05 AM on 12 February 2016The gutting of CSIRO climate change research is a big mistake
Supplemental reading:
Funding and job cuts at Australia's climate change research body could undermine the country's goal of dominating the Asian premium food market by placing farmers at a disadvantage to U.S. and European competitors.
Australia's extreme weather means farmers rely heavily on climate change forecasts from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) to mitigate the impact of bushfires, cyclones and droughts.
"In the next 30 years we will need to alter our farming habits due to rainfall, heat, drought, soil moisture. Australian farmers need the best data and predictions," said former chief of CSIRO marine research Tony Haymet.
Without such data, Haymet said Australia and its farmers will be "at a disadvantage in the long run".
Thousands of international climate scientists signed a protest letter over the job losses, saying: "If these climate science research cuts at CSIRO proceed without being filled elsewhere, then Australia will not develop its capability to assess the accelerating risks associated with climate change".

One Planet Only Forever at 00:55 AM on 12 February 2016No climate conspiracy: NOAA temperature adjustments bring data closer to pristine
@23,
What is despicable is all the smart fortunate people willing to develop and pitch the deliberately misleading marketing.
The misuse of the powerful science of marketing has been far more damaging than the misuse of nuclear science to make weapons (misleading marketing can even be seen to have contribted to the efforts to justify the 'live testing' of the two different types of nuclear bombs the US had developed).
Misleading marketing creating and appealing to personal desires, winning over thoughtful conscientious responsible thinking, is the reason for the growth and prolonging of every pursuit of profit that was able to be made popular in spite of it not having been proven to be providing a lasting benefit for all of humanity. It is also the (lack of ) reason behind almost every violent conflict (most of which can clearly be seen to be illigitimate grabs at wealth and power for the benefit of only a portion of humanity, sold as things like "Defense of Freedom, or Defense of Religion" ... when in reality the promoters of the conflicts are fully aware that they are Offensive).
The greatest threat to humanity is "Misleading Marketing".

"Daffodils in Bloom"
This has happened before, and especially before all the noteriety regarding global warming. Quite often there may be a warm spell and trees start to bud early, and it gets cold again and the buds die and the tree will bud again, when the buds will sustain.
One needs to realize, that there are several regions of the United Kingdom, which exist, and have done so for many, many, years, in a Sub Tropical Cimate. There are Palm Trees, and other such 'flora', which is endemic to the United Kingdom - thanks in part to the Gulf Stream and the North Atlantic Drift.
There will be more daddodils to come; in March or April, they will bloom again, just as they have before.

Tom Curtis at 23:48 PM on 11 February 2016The gutting of CSIRO climate change research is a big mistake
ryland @13, John Church and Neil White (both with the CSIRO) are among the foremost experts on sea level rise, which is a very closely related field to that of ocean heat content. The CSIRO's observatory at Cape Grim is probably the leading southern hemisphere observatory of CO2 and other trace gas concentrations. It is certainly used by NOAA in developing its global average from measurements in a range of latitudes.
Both groups are in the area lined up for the most cuts, and have work very closely identified with the criteria of what the CSIRO will apparently no longer do. Further, given cuts to US research, that (for example) has meant even Mauna Loa has had to resort to crowd funding to maintain its CO2 observations, the assumption that we can casually dispose of Cape Grim is absurd.
That raises the additional point that the willingness of conservative governments in the US and Canada to shoot the messenger on global warming be defunding science (and in Canada's case, defunding the keeping of scientific data), the assumption that Australian's contribution is now redundant is absurd.
-
Tom Curtis at 23:24 PM on 11 February 2016The gutting of CSIRO climate change research is a big mistake
bozza @various, I will not go into details because it is off topic, and politics to boot; but I agree with Ryland that Abbots 'captain's pick' of a new Lomborg center in Australia had no bearing on his dismissal.
ryland @12, as it happens, research into the link between smoking and cancer continues apace. That is because, the link between smoking and lung cancer is statistically well established, but there are less obvious links with other forms of cancer, but also, because the link between smoking and cancer was established statistically, the exact causal relationship between smoking and cancer has not been established. Therefore crucial research remains to be done which will help in the treating of smoking caused cancers.
In climate science, although the causal link between anthropogenic emissions and global warming is settled science, the exact value of climate sensitivity, the specific effect of clouds as a feedback, and in interaction with aerosols, are only roughly constrained. Further, the process of downscaling model predictions so that predictions at a resolution useful to planners is still in its infancy. Finally, until we have super computers several thousand times faster than the current crop, single model large ensemble experiments are not realistic. Until we can do those, however, we cannot make significant progress in determining which are the more accurate models, and rely on an ensemble of model predictions to determine error ranges on predictions. The CSIRO runs a key model in that ensemble, and its loss would significantly impact the quality of model predictions.
These are issues quite apart from the obvious point that you cannot assess effectiveness of mitigation without the observational measures that were used to discover that mitigation is necessary. I am sure experts in the various fields could think of more relevant factors.
Please note that I do not object to the CSIRO changing its focus. Had an announcement been made that 30 positions would be lost from current climate research to start increasing CSIRO research on mitigation (which already exists), nobody would have batted an eyelid. What has me outraged is the blind managerialism that first determines on vague mantras "we need renewal" how many cuts will be made without, in the first instance, determining which particular research activities are currently productive, and will be into the future; and which are not.

After a scan of the internet I can't find much coverage of the CSIRO decision to dismiss/redeploy/give teduncancy to 350 climate scientists. apart from a piece in The Guardian reporting that 600+ scientists from around the worldd have signed a circulatiing letter of protest. Is the fuss in Australia just a storm in a parochial teacup? Just what is it that climate scientists at CSIRO do that isn't or can't be peplicated elsewhere in the world? The link between smoking and cancer is unequivocally proven and there is little if any research focussed on proving that link so is there need to focus on the association between CO2 and climate change as that link icnsidered settled? It seems sensible to say well climate change is here its not going to go away let's see what we can do to mitigate/ameliorate/adapt our lifestyles to its effects. The focus now isn't on the link between smoking and cancer but on how to better diagnose and traet cancer caused by smoking or due to other causes. Why not for climate change ?

BaerbelW at 22:18 PM on 11 February 2016The gutting of CSIRO climate change research is a big mistake
Doing work on mitigation & adaptation is neccessary but it needs to be done in addition to and not instead of basic climate research. If you no longer collect the basic data like CO2 concentrations or ocean heat how will you ever be able to know that what you do for mitigation actually has the desired effect or that any adaptation will really help?

@27, I have found the most fun to be making deniers refuse to acknowledge the term 'multi-year sea-ice'.... they keep trying to dismiss you with a time series of sea ice!
I love spilling coffee....what can I say!

Adjustment is not allowed, ever. Nothing vibrates and stagnation is not close to death.... the industrial revolution just happened mannnnnnnnnnnnnnn!! Yay, i can do i-phone graphic design and am not standing on the shoulders of any giants: no mum, promise etc.....

Kevin C at 19:18 PM on 11 February 2016Hansen's 1988 prediction was wrong
planet8788: Accoding to Meinhausen et al, the Montreal gas forcing (CFCs etc) peaked at about 0.32 W/m2 and is projected to drop to about 0.2 W/m2 by 2050. Do you disagree with those figures?

Tom Curtis at 15:36 PM on 11 February 2016Hansen's 1988 prediction was wrong
planet8788 @41, based on Gavin Schmidt's calculation, the Hansen 88 GHG concentration trajectories would have resulted in a net forcing increase relative to 1983 of 3.35 W/m^2 for Scenario A, 2.33 W/m^2 for Scenario B, and 1.41 W/m^2 for Scenario C. The actual increase was 2.2 W/m^2, or just below Scenario B and 56% greater than scenario C. More importantly, Scenario C has a slightly declining forcing from 2000, while anthropogenic forcings have continued to rise at an approximately linear rate:
Therefore it is seriously misleading to say "we're still at Scenario C".
Further, and importantly, we are in our present position of a forcing increase slightly below Scenario C in part because of a significant, and ongoing effort to reduce GHG emissions. The correct conclusion, therefore, is not that everything will be fine, but that we need to continue, and indeed strengthen substantially those efforts. In the medium term (30 to 50 odd years), we need to bring net emissions to effectively zero. BAU will not do that. Even a continuation of current mitigation efforts will not do that.
Finally, even if we do that we will reach a mean global temperature close to 2 C above the preindustrial average. Likely even that increase will be significantly harmful, and certainly it will be catastrophic for some. It is just a much better scenario than genuine BAU which, if pursued in the long term would see the tropics become seasonally uninhabitable for large mammals (ie, humans, sheep, cattle, and dogs would die of heat prostation within a few days of unairconditioned exposure to 'normal' heatwaves under that scenario for more than a day or so).
That we are doing very slightly better than what Hansen considered the most likely scenario in 1988 is hardly a great comfort.

In fact, CFC concentrations are still going down and it looks like they have a long way to go. So that is still going to continue offsetting warming by CO2.
The ocean is absorbing more CO2 than expected. We probably don't have much to worry about. The main wildcard is methane.

planet8788 at 14:54 PM on 11 February 2016Hansen's 1988 prediction was wrong
Okay, So, we've increased CO2 emissions and we're still at Scenario C. So we have little to worry about. Becauses CFC emissions aren't going to go back up. CO2 emissions will probably peak by 2030...
The only wildcard is methane. And that is evolving much much slower than expected.

Tom Curtis at 12:57 PM on 11 February 2016The gutting of CSIRO climate change research is a big mistake
A response by the head of the CSIRO.
I think his view is wrong headed. I agree we should ramp up studies on mitigation, but:
1) The key policy on mitigation, introducing a carbon price, is already well known, and is more a matter of economics than science; and
2) The impact of more technical fixes (geoengineering) cannot be assessed without the sort of knowledge generated by the division of the CSIRO he is in the process of gutting.
Perhaps he has in mind more specific studies such as research into how to reduce methane emissions from cattle, or rice agriculture; or research into improving renewable energy sources. However, while such research is welcome, with a carbon price it will be driven rapidly by the private sector wheras the basic climate research currently being conducted by the CSIRO will not be.
This is like the reasons he gave in his original statement. Then the cuts were justified, apparently, because staff turnover at the CSIRO was less than in commercial organizations (which is not a reason at all), and because it would create a career path (but apparently in an organization in which careers will be terminated early with little prospect of alternative funding). His belief appears to be that the 9 odd years spent becoming a scientist should be rewarded with careers of a little less than that in order to encourage new students to dedicate that time for a truncated career.
It appears to me that he considers 'renewal' a good thing, without understanding that renewal must be for a reason, and too a purpose. Instead he has put renewal first as a management mantra, made massive changes on that basis with only post hoc justification at best.

Tom Curtis at 12:13 PM on 11 February 2016Other planets are warming
sjw40364 @41, the last NASA article to which you link states:
"Even more impressive was the substorm's power. Angelopoulos estimates the total energy of the two-hour event at five hundred thousand billion (5 x 1014) Joules. That's approximately equivalent to the energy of a magnitude 5.5 earthquake."
Averaged over the Earth's surface, that represents 0.00014 W/m^2. For comparison, the reduction in release of energy from the Earth's surface due to the increase in CO2 since the preindustrial is 1.9 +/-0.19 W/m^2. Even the error term of that calculation is 1400 times greater than the "new" energy to which you point.
Worse, this is not newly discovered energy. According to NASA, the Themis spacecraft have "... made three important discoveries about spectacular eruptions of Northern Lights called "substorms" and the source of their power" (emphasis added). They have not made the discovery of substorms themselves, which are well known, and the energy of which are already accounted for in the 889,000 x 10^14 Joules from 1997-2010 (0.00035 W/m^2) discusses by Tenfjord and Ostgaard (and @34 above).
Further, it is not new energy. The Sun has had a solar wind since its inception, and the Earth a magnetic field as far back as paleomagnatism can be discerned (at least 500 million years, and probably at least 4 billion years). This energy, therefore, cannot account for the sudden, rapid rise in global temperatures over the 20th century.
Frankly, you most recent post adds nothing new to the discussion, illustrating only your determination to shut your eyes to counter evidence with regard to your pet theory. (The post before that is even worse, as it grossly misrepresents the facts with regard to warming episodes in the glacial/interglacial cycle and the temperature history of the last 25,000 years.)

No climate conspiracy: NOAA temperature adjustments bring data closer to pristine
HK - A lovely example. As I stated on WUWT sime time back [archived link]:
It could be argued that it’s better to look at raw temperature data than data with these various adjustments for known biases. It could also be argued that it’s worth not cleaning the dust and oil off the lenses of your telescope when looking at the stars. I consider these statements roughly equivalent, and (IMO) would have to disagree.
Needless to say, this was not received well in deniersville.

sailingfree at 00:58 AM on 11 February 2016A Response to the “Data or Dogma?” hearing
Great post!
A broader perspective: Why the troposphere?
To see if the Globe is warming, see the ocean heat content.
To see if the climate is changing, see the global surface temperatures.

According to the denier's logic, the left of these two images of Uranus is the correct one because it's based on raw data while the right is a fraud because the Keck telescope on Hawaii used adaptive optics to counter the turbulence in the Earth's atmosphere!

Denier 1: 'You are not accounting for urban heat island effects on the temperature data! It is all a fraud!'
Denier 2: 'You are adjusting the temperature data! It is all a fraud!'
What's really sad... all too often the 'Denier 1' and 'Denier 2' comments are coming from a single person.
