Despite the failure of any climate model to predict the climate, the Obama administration is increasing the cost and strictness of regulation because of what it sees as the “social cost of carbon dioxide.”

Despite the failure of any climate model to predict the climate, the Obama administration is increasing the cost and strictness of regulation because of what it sees as the “social cost of carbon dioxide.”

[E]ssentially, the government is now incorporating newer climate models that capture the future damage from sea-level rise more explicitly. Those models also project that agriculture will suffer more heavily in a hotter world. So, in its central estimate, the federal government now assumes a ton of carbon-dioxide emitted in 2013 does roughly $36 in damage, rather than its previous estimate of $22, with the value rising each year.

Meanwhile, new data also suggests increased carbon dioxide in the atmosphere might actually be beneficial, not damaging.

Shouldn’t the EPA and the Obama administration get their heads out of the sand?

The predictions of seventy-three climate models are compared to real data and not one comes even close to reality.

The predictions of seventy-three climate models are compared to real data and not one comes even close to reality.

Remember: computer modeling is not science research. It does not tell us anything about the actual climate. It is instead theoretical work useful for trying to understand what the data actual is telling us.

Computer modeling, however, is totally useless if it doesn’t successfully mimic that actual data. Since all of these climate models fail to do this, they very clearly show that they do not understand the climate itself, and are not valid theories to explain its processes. If the scientists who created them were honest about these results, they would immediately go back to the drawing board and rewrite these models.

I unfortunately have serious doubts they will do this.

The Sun makes the scientists look good — for now!

1:53 pm

NOAA today released its monthly update of the Sun’s sunspot cycle, covering the period of May 2013. As I have done every month for the past three years, I have posted this latest graph, with annotations to give it context, below the fold.

For the third month in a row, the Sun has shown increased sunspot activity. Though the total activity continues to remain well below all predictions, it appears that the Sun is going to produce a double-peaked maximum, as predicted by some solar scientists back in March. Be aware however that this prediction isn’t based on any real understanding of the physical processes that produce sunspots but is instead based on the fact that the Sun has sometimes done this in the past. If you asked these scientists why the Sun sometimes produces a double-peaked maximum they will wave their arms about but will really not be able to tell you.

A new study suggests a link between CFCs, the ozone hole, and climate change.

9:47 am

The uncertainty of science: A new study suggests a link between CFCs, the ozone hole, and climate change.

“Most conventional theories expect that global temperatures will continue to increase as CO2 levels continue to rise, as they have done since 1850. What’s striking is that since 2002, global temperatures have actually declined – matching a decline in CFCs in the atmosphere,” Professor Lu said. “My calculations of CFC greenhouse effect show that there was global warming by about 0.6 °C from 1950 to 2002, but the earth has actually cooled since 2002. The cooling trend is set to continue for the next 50-70 years as the amount of CFCs in the atmosphere continues to decline.”

The data is interesting, though hardly as conclusive Lu claims. It does illustrate again how incredibly complex climate science is, and how many factors influence it that we can’t yet completely quantify.

Based both on computer models and satellite data a team of scientists has concluded that the increase carbon dioxide in the atmosphere is making arid regions greener.

Based both on computer models and satellite data a team of scientists has concluded that the increase carbon dioxide in the atmosphere is making arid regions greener.

This study illustrates one possibility that is always ignored in the climate debates — that there is a really good chance that the increase of CO2 in the atmosphere will be beneficial.

To the horror of global warming alarmists, the climate refuses to warm.

To the horror of global warming alarmists, the climate refuses to warm.

For those who are regular readers here at Behind the Black, none of the data described by Peter Ferrara in this article will be a surprise. I have been reporting these facts for years. However, the article provides a nice outline of what we know, and includes this sentence near the end that sums up the true problem we face:

Has there ever in history been such an almighty disconnect between observable reality and the delusions of a political class that is quite impervious to any rational discussion?

Who are the real climate deniers?

Who are the real climate deniers?

I very much dislike the use of the term “deniers”, no matter who it is applied to, since it lowers the civility of the discussion. Nonetheless, the article is a nice thumbnail summary of the climate field, both in terms of the players as well as the areas of uncertainty and confusion. It also provides a clear illustration of the contrast between the two sides and how they tend to discuss these issues, best summarized by this quote:

It is also telling that in a radio debate between Harris [the skeptic] and Rhynas [the global warming advocate] that took place following Rhynas’s initial presentation, the former agreed to take questions from the public but the latter refused.

Climate scientists have been forced to revise their climate models due to the unexpected refusal of the climate to warm since the late 1990s.

The uncertainty of science: Climate scientists have been forced to revise their climate models due to the unexpected refusal of the climate to warm since the late 1990s.

In related news, the certainty of some ignorant politicians: A Democratic senator used the Oklahoma tornado to rant against Republicans who have expressed skepticism about human-caused global warming. Update: Senator Barbara Boxer (D-California) followed up by blaming the tornado on global warming while pushing her carbon tax bill today.

The first story attempts very hard to keep the narrative alive that we are all going to die from global warming, even though the gist is that the warming has stopped and all the predictions of global warming scientists have been wrong. The second story illustrates the typically close-minded attitude of liberal politicians. The senator not only refuses to recognize the new data showing that warming has stopped, he has accepted the global warming narrative completely, including the entirely false claim that extreme weather is rising because of global warming.

The myth of the scientific liberal

11:33 am

The myth of the scientific liberal.

The core trait of a scientific mind is that when its commitments clash with evidence, evidence rules. On that count, what grade do liberals deserve? Fail, given their reaction to the latest evidence on universal health care, global warming, and universal preschool.

The author then delves into each of these topics and shows how the liberal community refuses to deal with the evidence.

The European Union’s program to reduce carbon emissions is in disarray.

The European Union’s program to reduce carbon emissions is in disarray.

The article at the link is probably one of the worst written stories in the history of journalism. It is incoherent, disorganized, and confused. Moreover, the authors are so in favor of the regulations to limit fossil fuels that they are unable to even consider any reasons which might explain why Europe’s carbon credit market is collapsing and why the EU’s legislators rejected a rescue plan to save it.

In fact, because of their biases, the authors buried the real story, which is this:

Parliamentarians on April 16 voted 334 to 315 for blocking the carbon market rescue.

“This is the first time I can remember when parliament has put economic survival and jobs ahead of green orthodoxy,” said Roger Helmer, a member of the U.K. Independence Party who has been in the parliament for 14 years and opposes emissions trading. “It marks an absolute watershed.”

The bad economy and high debt in Europe is making the idea of raising taxes and adding more restrictions on fossil fuels very unappealing to politicians.

The high peak in tornado in 2011, the most in fifty years, was quickly attributed to global warming. Eric Berger asks: How does this explain this year’s low number, the fewest in fifty years?

If you click on the first link, you will see that the global warming scientists quoted, Kevin Trenberth, Michael Mann, and Gavin Schmidt, were all involved in the climategate emails, where they came off very badly. Moreover, there have been significant questions about the work of Michael Mann himself. I also wonder if these guys will have anything to say about the dearth of tornadoes today.

The Fantasy of Extreme Weather

10:06 am

This week there were three stories describing new research proving that global warming is going to cause an increase in the number and violence of extreme weather events. Each was published in one of the world’s three most important scientific journals.

Sounds gloomy, doesn’t it? Not only will extreme heatwaves, cold waves, and droughts tear apart the very fabric of society, you will not be able to drink your soda in peace on your next airplane ride!

However, one little detail, buried in one of these stories as a single sentence, literally makes hogwash out of everything else said in these three articles.

Global warming: time to rein back on doom and gloom?

1:57 pm

From a global warming advocate: Global warming: time to rein back on doom and gloom?

Prediction, as they say, is tough, especially when it’s about the future – and that’s especially true when it comes to the climate, whose complexity we only partially understand. It is, as we all know, naturally immensely variable. And the effect of human intervention is subject to long timelags: it will be decades, even centuries, before the full consequences of today’s emissions of carbon dioxide become clear.

As a result, scientists and policymakers draw on the past to predict the future. Until now, they have therefore placed much weight on the rapid temperature increases in the Eighties and Nineties. But for at least a decade, these have dramatically slowed, even as carbon dioxide emissions have continued to increase. [emphasis mine]

Or as I like to say, every climate model proposed by every global warming scientist has been proven wrong. They all predicted the climate would warm in lockstep with the increase in CO2. It hasn’t.

This is not to say the climate hasn’t warmed in the past five centuries (though some of the data used in for the past 150 years is sadly suspect). What isn’t clear is why. It might be the rise in carbon dioxide. It might also simply be the lingering warming the Earth is experiencing as the last ice age ends. Or it might be because of the Sun.

The field of climate science is very complex, confusing, and in its infancy. We just don’t know yet, and anyone who says they do is not a good scientist.

The weak solar maximum continues

10:27 am

Late last night NOAA released its monthly update of the Sun’s sunspot cycle, covering the period of March 2013. As I have done every month for the past three years, I am posting this latest graph, with annotations to give it context, below the fold.

While the Sun’s output of sunspots increased in March, it did not do so with much vigor, with the numbers still far below all predictions while also showing an overall decline since a single strong peak in October 2011.

The scientists who attempted to re-invent Michael Mann’s hockey stick global warming graph and were caught fudging their data have admitted their data is worthless

12:17 am

The scientists who attempted to re-invent Michael Mann’s hockey stick global warming graph and were caught fudging their data have essentially admitted that their data is worthless.

This is what they say in a FAQ they have added to their paper:

Q: What do paleotemperature reconstructions show about the temperature of the last 100 years?

A: Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions. [emphasis mine]

They are basically admitting that the data used to create the temperature rise of their hockey stick during the past 100 years is unreliable and therefore useless for scientific purposes. Which raises the question: Why did they publish it in the first place? See especially this analysis of this paper and the press’s reaction to it by climate scientists Roger Pielke.

James Hansen is retiring from NASA and will dedicate his time to global warming activism.

James Hansen is retiring from NASA and will dedicate his time to global warming activism.

All that is really changing is that Hansen will no longer work for the government. The activism has been going on for a very long time.

Also, it is interesting how this New York Times article seems very unaware of this fact, which makes all of Hansen’s global warming claims very suspect. Might the Times not want the public to know this annoying detail?

The uncertainty of science: “The fact that global surface temperatures have not followed the expected global warming pattern is now widely accepted.”

This quote above refers to scientists in the climate field, who are now admitting that for the past 20 years the climate has shown no warming, despite the continuing increase in CO2 in the atmosphere and their computer models that all predicted increased temperatures because of that CO2.

More fraud in climate science

3:17 pm

Fraudalent data

Steve McIntyre, the man who had demonstrated that Michael Mann’s hockey stick graph was a fraud, has now demonstrated that the work of a group of climate scientists attempting to resurrect it is even more fraudulent. It seems that in order to recreate the illusion of warming in the past four hundred years, the scientists, led by geologist Shaun Marcott, changed the dates on a series of ocean cores in order to get the results they wanted.

McIntyre found that Marcott and his colleagues used previously published ocean core data, but have altered the dates represented by the cores, in some cases by as much as 1,000 years.

Most significantly, the scientists made no explanation for changing these dates. It is as if they wanted to hide this decline, y’know?

The chart on the right, by McIntyre, illustrates the fraud. The black line shows the temperature numbers of the ocean cores used by Marcott. The red line shows the temperature numbers, as originally published in the scientific literature, for these ocean cores.

The discrepancy here is so egregious that it screams at you. More important, as John Hinderaker says,

The dirty little secret of electric cars.

6:17 pm

The dirty little secret of electric cars.

A 2012 comprehensive life-cycle analysis in Journal of Industrial Ecology shows that almost half the lifetime carbon-dioxide emissions from an electric car come from the energy used to produce the car, especially the battery. The mining of lithium, for instance, is a less than green activity. By contrast, the manufacture of a gas-powered car accounts for 17% of its lifetime carbon-dioxide emissions. When an electric car rolls off the production line, it has already been responsible for 30,000 pounds of carbon-dioxide emission. The amount for making a conventional car: 14,000 pounds. …

So unless the electric car is driven a lot, it will never get ahead environmentally. And that turns out to be a challenge. Consider the Nissan Leaf. It has only a 73-mile range per charge. Drivers attempting long road trips, as in one BBC test drive, have reported that recharging takes so long that the average speed is close to six miles per hour—a bit faster than your average jogger.

In other words, government subsidies for electric cars are nothing more than another feel-good program, accomplishing nothing.

New computer models find that the tropical rain forests will not be harmed by increased carbon dioxide in the atmosphere.

4:06 pm

The uncertainty of science: New computer models find that the tropical rain forests will not be harmed by increased carbon dioxide in the atmosphere.

Tropical forests are unlikely to die off as a result of the predicted rise in atmospheric greenhouse gases this century, a new study finds. The analysis refutes previous work that predicted the catastrophic loss of the Amazon rainforest as one of the more startling potential outcomes of climate change.

In the most extensive study of its kind, an international team of scientists simulated the effect of business-as-usual emissions on the amounts of carbon locked up in tropical forests across Amazonia, Central America, Asia and Africa through to 2100. They compared the results from 22 different global climate models teamed with various models of land-surface processes. In all but one simulation, rainforests across the three regions retained their carbon stocks even as atmospheric carbon dioxide concentration increased throughout the century.

The study provides “robust evidence for the resilience of tropical rainforests”, says lead author Chris Huntingford, a climate modeller at the UK’s Centre for Ecology and Hydrology in Wallingford. But uncertainties remain, he adds.

First, this prediction is based on a computer model, which is as likely to be as right as the previous pessimistic predictions. With that in mind, no one should start dancing for joy. The long term consequences of increased carbon dioxide in the atmosphere remain unknown.

Second, I am baffled by the previous predictions that favored catastrophe for the tropical jungles because of increased levels of carbon dioxide. Plants breath CO2. They prosper from it. If you put more in the atmosphere they will thrive. Moreover, the tropical jungles are already hot, and the plant life there is adapted to that heat. Raising the global temperature should not hurt them significantly.

Finally, faced with a result that defuses all the crisis-mongering of the global warming crowd, the author of the article feels obliged at the end to emphasis their new bugaboo: extreme weather! It’s coming! Duck your heads!

But don’t worry. When weather extremes also fail to appear, they will find something else to scream about.

We don’t need no solar maximum

3:37 pm

It is that time again! Today, March 4, NOAA released its monthly update of the Sun’s sunspot cycle, covering the period of February 2013. As I do every month, I am posting this latest graph, with annotations to give it context, below the fold.

Once again, the Sun has shown a complete inability to produce sunspots, at the very moment it had been predicted to be rising towards its maximum in the sunspot cycle. The numbers in February plunged from the tepid rise we saw in January to below the crash we saw in December. Right now, when the Sun is supposed to peaking, it is instead producing sunspots in numbers as low as seen in 2011, at the very end of the last solar minimum.

In an interview in Australia, the head of the IPCC has admitted that the climate has stopped warming now for the past seventeen years.

3:29 pm

Consensus! In an interview in Australia, the head of the IPCC has admitted that the climate has stopped warming now for the past seventeen years.

No computer climate model offered in any IPCC report predicted this long pause in warming. They all instead insisted that because of the increase of carbon dioxide in the atmosphere, the global temperature would have to rise, and do so quickly and with catastrophic results.

In other words, those models were wrong. The climate is very complicated, and we don’t yet understand very well how it functions.
