In the final draft of its new report the IPCC has significantly slashed its predictions for how much the climate will warm in the coming decades.

9:29 pm

From the second to the final draft of its newest report the IPCC significantly slashed its predictions for how much the climate will warm in the coming decades.

In the second draft of the Fifth Assessment Report it had broadly agreed with the models that the world will warm by 0.4 to 1.0 Cº from 2016-2035 against 1986-2005. But in the final draft it quietly cut the 30-year projection to 0.3-0.7 Cº, saying the warming is more likely to be at the lower end of the range [equivalent to about 0.4 Cº over 30 years]. If that rate continued till 2100, global warming this century could be as little as 1.3 Cº.

This will bring the IPCC’s predictions more in line with the reality of the past two decades, which has seen a complete pause in any warming.

This is actually very good news, as it suggests that the good scientists in the climate community are beginning to regain control of the science. Rather than bend to the political winds, the IPCC is being forced to bend to the data itself. Nonetheless, no one should be sanguine about the situation. As noted by Christopher Monckton at the link,

Multiple lines of evidence now confirm that the models and consequently the IPCC have overestimated global warming. Yet neither that misconceived organization nor any of its host of unthinking devotees has displayed any remorse. Instead, they persist in maintaining that the warming is temporarily paused, though they cannot really explain why; or they blame particulate aerosols, their get-out-of-jail-free fudge-factor; or they pretend warming is really continuing unabated, saying it has gone into hiding deep in the oceans where, conveniently, we cannot measure it, or that the Earth-atmosphere system has a fever driven by four atom-bombs’-worth of heat content increase every second.

What they are not prepared to countenance, notwithstanding the real-world, measured evidence, is the growing probability that they and their precious models have so badly misunderstood the climate, or so well understood it and so badly misrepresented it, that global warming is simply not going to occur at anything like any of the exaggerated rates that they had until now so confidently over-predicted.

Read the whole thing. Look especially at Figure 9, the last figure, as it shows the data in comparison with the predictions in all the IPCC reports.

How global warming activists ended up getting stuck in the ice fields surrounding Antarctica.

How global warming activists ended up getting stuck in the ice fields surrounding Antarctica.

The first error expedition leaders made was under-estimating the prevailing sea ice conditions at Mawson Station, their destination. The scientists seemed to be convinced that Antarctica was a warmer place today than it had been 100 years earlier, and thus perhaps they could expect less sea ice there. This in turn would allow them to charter a lighter, cheaper vessel.

And then there’s this:

Why the vessel got trapped in the first place may be because [project leader and professor Chris] Turney never bothered to look at sea ice charts, which showed near record high levels of sea ice surrounding Antarctica. Moreover, Turney even denied that the overall sea ice trend was expanding around the continent. Fox News writes, “Turney said it was ‘silly’ to suggest he and 73 others aboard the MV Akademic Shokalskiy were trapped in ice they’d sought to prove had melted. He remained adamant that sea ice is melting, even as the boat remained trapped in frozen seas.”

Did he expect to find less ice than Mawson did 100 years earlier? This appears to be what he expected, given his expedition’s planning. [emphasis mine]

In other words, this group and its so-called scientific leader are typical of the entire global warming climate community. Facts are irrelevant. The Earth is warming, the icecaps are disappearing, and to hell with any data that says otherwise.

Eventually, however, reality bites. Personally, I would much rather focus on reality first, so that I am prepared to deal with it when it jumps up at me.

Global sea ice area is now at its second highest level ever recorded, and closing in on an all time record.

The uncertainty of science: Global sea ice area is now at its second highest level ever recorded and is closing in on an all time record.

The link is also amusing in that it includes some interesting predictions made by global warming scientists and politicians in recent years, all predicting that the Arctic Ocean would be ice free by 2013.

Reddit bans any skepticism of global warming.

2:57 pm

The certainty of the global warming crowd: Reddit bans everyone from expressing skepticism of global warming.

In a move that has been described by one British academic as “positive censorship”, a Reddit moderator has announced that Reddit is becoming “increasingly stringent with deniers”. The Reddit moderator says climate “contrarians” were too often expressing “uninformed and outspoken opinions”, and so the site decided to adopt a much more “proactive moderation”. Now, whenever a user makes a “potentially controversial submission” on climate change, the moderators issue that user with a “warning”. If the user persists in posting “potentially controversial submissions”, he’s “banned from the forum”.

The worst part of this is the reaction of Reddit’s moderators:

Reddit’s moderators are really happy with the results of their war against the expressers of “outspoken opinions” on climate change. They found that by “negating the ability of this misguided group to post to the forum” (a long-winded way of saying “banning them”), there has been a “change in the culture within the comments”. “Where once there were personal insults and bitter accusations, there is now discussion of the relevant aspects of [scientific] research”, we are told. In short, having expelled outspoken, controversial “deniers” from its forums, Reddit now finds that its discussions of climate change are more measured – that is, on-message, conformist, uncontroversial.

How convenient. You don’t like the opinions of those who disagree with you, so you ban them. Sure solves the problem of winning debates, doesn’t it?

I wouldn’t object if the moderators just banned insulting and offensive comments. I do that here at Behind the Black. What they’ve apparently done instead is to ban all opposing opinions, which is far different.

More than half the U.S. is covered with snow this November, the most in ten years.

8:08 pm

More than half the U.S. is covered with snow this November, the most in ten years.

The certainty of climate scientists:

Kevin Trenberth, of the National Center for Atmospheric Research, agreed the surprising amount of snowfall is a separate issue from climate change. “If you warm up the atmosphere, you can actually get heavier snowfalls in winter,” Trenberth said. “That’s one of the ironic things about global warming. Maybe we can say that without climate change, it would be colder still. [emphasis mine]

In other words, according to Trenberth the increased snow cover and cold temperatures are evidence of global warming.

No more seasonal hurricane predictions from Colorado State University.

9:49 am

No more seasonal hurricane predictions from Colorado State University.

They lost their funding, which is no surprise.

At the beginning of this year’s season, the team predicted 18 named storms. Nine of those, it said, would become hurricanes. Four would be major hurricanes. Here’s how it shook out: There were 13 named storms. Only two became hurricanes. Neither was a major hurricane.

They, like NOAA, expected an increase in extreme hurricanes and were wrong. In fact, they were so wrong that they illustrated clearly how much a guess all of these climate predictions are. You might as well flip a coin.

This year’s hurricane season, predicted to be above average, was the weakest in decades.

9:30 am

The uncertainty of climate science: This year’s hurricane season, predicted to be above average, was the weakest in decades.

This failure also continues a pattern seen in recent years, where the number of actual hurricanes ends up far below their prediction, but the number of named hurricanes still ends up about right (see the charts on the prediction link above). I noted this in 2012, and now it has happened again. As I said then,

I wonder if their naming process was fudged to get them the numbers they wanted. While it might be possible to do that with the naming process of tropical storms, it is far more difficult to fudge the number of actual hurricanes. My skeptical nature and the recent willingness in the climate field to fiddle with data probably makes me more suspicious than I should be.

Thus to me, these seasonal hurricane predictions are becoming increasingly suspect.

A new study suggests that the variation of the cosmic ray flux during the solar cycle has little influence on the climate.

The uncertainty of science: A new study suggests that the variation of the cosmic ray flux during the solar cycle has little influence on the climate.

The study seems statistical in nature, which leaves me skeptical. Nonetheless, the link between cosmic rays and climate change remains tenuous, with only one study at CERN providing any evidence that cosmic rays might have an influence.

The sun goes boom!

11:34 am

It is always best to admit when you are wrong as soon as you find out. Last month, in reporting NOAA’s monthly update of the solar cycle, I unequivocally stated that

My interpretation of this data tells me that almost certainly the solar maximum has ended. We might see some later fluctuations whereby the sunspot number jumps, but the Sun is clearly beginning its ramp down to solar minimum.

Well, I spoke too soon. Last night NOAA posted the newest update of the solar cycle, and it shows that in October the Sun was more active then it has been in two years. In fact, for only the second time this entire solar cycle the Sun’s sunspot activity actually came close to matching the predictions of scientists. This month’s graph is posted below the fold, with annotations.

Extreme weather events in 2013 are at an all time low.

9:53 am

Another global warming prediction fails: Extreme weather events in 2013 are at an all time low.

There have been many forecasts in the news in recent years predicting more and more extreme weather-related events in the US, but for 2013 that prediction has been way off the mark. Whether you’re talking about tornadoes, wildfires, extreme heat or hurricanes, the good news is that weather-related disasters in the US are all way down this year compared to recent years and, in some cases, down to historically low levels.

As I wrote back in April,

Global warming scientists have spent the past two decades telling us that we were all gonna die from increasing temperatures caused by the increase in CO2. Now that this prediction has proved false, they apparently are shifting gears. Instead, it is extreme events — big storms, long droughts, intense heatwaves — that are going to kill us.

But not only have they no evidence that the increase in CO2 will cause these extreme events, there is no evidence that more of these extreme events are even occurring.

In other words, these stories are mere political advocacy. They have nothing to do with science, but with propaganda, based on fantasy with the goal of trying to convince everyone that we are all gonna die if we don’t do exactly what these scientists say. [emphasis in original]

How the tentacles of the green environmental movement dominate the IPCC.

6:42 pm

How the tentacles of the green environmental movement dominate the IPCC.

The U.N. has charged the IPCC with weighing the evidence on climate change in an objective manner. The problem is that numerous IPCC personnel have ties to environmental groups, many of which raise funds by hyping the alleged dangers of climate change. This relationship raises a legitimate question about their objectivity.

The examples are legion. Donald Wuebbles, one of the two leaders of the introductory first chapter of the Working Group 1 report (a draft of which may be released next Monday)—has been writing awareness-raising climate change reports for the activist Union of Concerned Scientists for a decade. Another chapter of the full IPCC report, “Open Oceans,” is led by Australian marine biologist Ove Hoegh-Guldberg, who has written a string of reports with titles such as “Pacific in Peril” for Greenpeace and the World Wildlife Fund (WWF). Astrophysicist Michael Oppenheimer, in charge of another chapter of the IPCC report, “Emergent Risks and Key Vulnerabilities,” advises the Environmental Defense Fund (after having spent more than two decades on its payroll).

University of Maryland scientist Richard Moss is a former fulltime WWF vice president, while Jennifer Morgan used to be the WWF’s chief climate change spokesperson. Both are currently IPCC review editors—a position that’s supposed to ensure that feedback from IPCC external reviewers is addressed in an even-handed manner.

My own examination of the 2007 IPCC report found that two-thirds of its 44 chapters included at least one individual with ties to the WWF. Some were former or current employees, others were members of a WWF advisory panel whose purpose is to heighten the public’s sense of urgency around climate change.

Considering these facts, if the IPCC report even mentions the 15 year pause in warming it will be a remarkable thing.

The Antarctica icecap is now grown to be the largest it has been in 35 years.

2:51 pm

The uncertainty of science: The Antarctica icecap is now grown to be the largest it has been in 35 years.

Antarctic sea ice has grown to a record large extent for a second straight year, baffling scientists seeking to understand why this ice is expanding rather than shrinking in a warming world. On Saturday, the ice extent reached 19.51 million square kilometers, according to data posted on the National Snow and Ice Data Center Web site. That number bested record high levels set earlier this month and in 2012 (of 19.48 million square kilometers). Records date back to October 1978.

Uh, maybe the world isn’t warming as predicted?

German politicians openly admit they are trying to squelch any mention in the IPCC report of the recent 15 year pause in global temperature rise.

10:03 am

German politicians openly admit they are trying to squelch any mention in the IPCC report of the recent 15 year pause in global temperature rise.

Despite resistance from many researchers, the German ministries insist that it is important not to detract from the effectiveness of climate change warnings by discussing the past 15 years’ lack of global warming. Doing so, they say, would result in a loss of the support necessary for pursuing rigorous climate policies. “Climate policy needs the element of fear,” [German Green Party politician Hermann] Ott openly admits. “Otherwise, no politician would take on this topic.”

Germany’s Federal Ministry of Research would prefer to leave any discussion of the global warming hiatus entirely out of the new IPCC report summary. “In climate research, changes don’t count until they’ve been observed on a timescale of 30 years,” claims one delegate participating in the negotiations on behalf of German Research Minister Johanna Wanka of the Christian Democratic Union (CDU). The Ministry for the Environment’s identical stance: “Climate fluctuations that don’t last very long are not scientifically relevant.” [emphasis mine]

I must admire the Green Party politician for admitting that his approach to science and politics is the use of fear. He might be the most honest, if fascist, politician in the world!

The IPCC and the climate science community should be warned, however. Their reputation for honest science is already in the tank. If the IPCC report to be released later this week makes believe that the climate pause hasn’t happened their ability to persuade anyone will be gone forever.

The global warming scientists at the IPCC struggle to explain the lack of warming.

9:41 am

The global warming scientists at the IPCC struggle to explain the lack of warming.

Though scientists don’t have any firm answers, they do have multiple theories. Xie has argued that the hiatus is the result of heat absorption by the Pacific Ocean — a little-understood, naturally occurring process that repeats itself every few decades. Xie and his colleagues presented the idea in a study published last month in the prestigious journal Nature.

The theory, which is gaining adherents, remains unproved by actual observation. Surface temperature records date to the late 1800s, but measurements of deep water temperature began only in the 1960s, so there just isn’t enough data to chart the long-term patterns, Xie said. [emphasis mine]

This theory, that the oceans are absorbing all the heat, is one of the new favorite explanations for the lack of warming by advocates of global warming. However, as this article correctly notes, we have no good data to support it, and even fewer theories to explain it.

The truth is really summed up by the article’s last paragraph:

“This unpredicted hiatus just reflects the fact that we don’t understand things as well as we thought,” said Roger Pielke Jr., a professor of environmental studies at the University of Colorado in Boulder and vocal critic of the climate change establishment. “Now the IPCC finds itself in a position that a science group never wants to be in. It’s in spin management mode.”

Another leak from the IPCC shows that politicians in Belgium, Hungary, Germany, and the United States attempted to pressure the scientists writing the report to cover up the lack in global temperature rise since 1998.

7:11 pm

Another leak from the IPCC shows that politicians in Belgium, Hungary, Germany, and the United States attempted to pressure the scientists writing the report to cover up the lack in global temperature rise since 1998.

[L]eaked documents seen by the Associated Press, yesterday revealed deep concerns among politicians about a lack of global warming over the past few years. Germany called for the references to the slowdown in warming to be deleted, saying looking at a time span of just 10 or 15 years was ‘misleading’ and they should focus on decades or centuries. Hungary worried the report would provide ammunition for deniers of man-made climate change. Belgium objected to using 1998 as a starting year for statistics, as it was exceptionally warm and makes the graph look flat – and suggested using 1999 or 2000 instead to give a more upward-pointing curve. The United States delegation even weighed in, urging the authors of the report to explain away the lack of warming using the ‘leading hypothesis’ among scientists that the lower warming is down to more heat being absorbed by the ocean – which has got hotter.

Two points: First, for this article to refer to any legitimate scientist who questions the theory of human-caused global warming to be called a “denier” offends me beyond words, as regular readers of this website know.

Second, this leak proves once again the foolishness of allowing politicians to get involved in the scientific process. They should be kept as far away as possible, at all times.

Another look at the leaked IPCC draft report.

Another look at the leaked IPCC draft report. Key quote:

To those of us who have been following the climate debate for decades, the next few years will be electrifying. There is a high probability we will witness the crackup of one of the most influential scientific paradigms of the 20th century, and the implications for policy and global politics could be staggering.

The article also takes a close look at the contradiction between the data and the IPCC models and says this:

[W]hat is commonly called the “mainstream” view of climate science is contained in the spread of results from computer models. What is commonly dismissed as the “skeptical” or “denier” view coincides with the real-world observations. Now you know how to interpret those terms when you hear them.

A newly leaked revised draft of the upcoming IPCC report suggests that the climate uncertainties have significantly grown since the last report in 2007.

1:14 am

A newly leaked revised draft of the upcoming IPCC report suggests that the climate uncertainties have significantly grown since the last report in 2007.

Most important of all, the new IPCC draft finally admits that the climate has not warmed as predicted and that the climate field does not know why.

They recognize the global warming ‘pause’ first reported by The Mail on Sunday last year is real – and concede that their computer models did not predict it. But they cannot explain why world average temperatures have not shown any statistically significant increase since 1997.

They admit large parts of the world were as warm as they are now for decades at a time between 950 and 1250 AD – centuries before the Industrial Revolution, and when the population and CO2 levels were both much lower.

The IPCC admits that while computer models forecast a decline in Antarctic sea ice, it has actually grown to a new record high. Again, the IPCC cannot say why.

A forecast in the 2007 report that hurricanes would become more intense has simply been dropped, without mention. This year has been one of the quietest hurricane seasons in history and the US is currently enjoying its longest-ever period – almost eight years – without a single hurricane of Category 3 or above making landfall.

The worst aspect of this new draft, however, is how its conclusions completely ignore these admitted uncertainties.

In the new report, the IPCC says it is ‘extremely likely’ – 95 per cent certain – that human influence caused more than half the temperature rises from 1951 to 2010, up from ‘very confident’ – 90 per cent certain – in 2007. [Climate scientists Judith] Curry said: ‘This is incomprehensible to me’ – adding that the IPCC projections are ‘overconfident’, especially given the report’s admitted areas of doubt.

As I’ve noted before, though Curry favors the theory that the climate is warming, she is also a good scientist willing to honestly discuss the uncertainties of the science.

One last point: Most of these newly admitted uncertainties in the upcoming IPCC report were originally discussed in detail in the first IPCC report back in 1990. That 1990 report was an excellent and fair assessment of the overall knowledge of the field, at the time. Since then, none of the science has really been able to reduce any of these uncertainties significantly. All that happened in the ensuing years is that too many climate scientists and in the IPCC decided to make believe the uncertainties didn’t exist any more. Thus, later IPCC reports were filled with false certainty and an unreasonable insistence that the climate field understood what was going on.

These false certainties have now come back to bite that climate field, in the ass.

A good scientist, who also believes in global warming, explains the irrelevance of “extreme weather” to the climate change debate.

12:27 am

A good scientist, who also believes in global warming, explains the irrelevance of “extreme weather” to the climate change debate.

Yet [an increase in extreme weather] is not supported by science. “General statements about extremes are almost nowhere to be found in the literature but seem to abound in the popular media,” climate scientist Gavin Smith of the NASA Goddard Institute for Space Studies said last month. “It’s this popular perception that global warming means all extremes have to increase all the time, even though if anyone thinks about that for 10 seconds they realize that’s nonsense.”

The scientist writing this op-ed is Bjorn Lomborg. He gives a lot of details. Here’s just one:

Global warming, in general, will mean higher temperatures. This causes more heat waves — more extreme weather. But it also causes fewer cold waves — less extreme weather. Many more people die from excessive cold than excessive heat, so fewer people will die from cold and heat in the future. By mid-century, researchers estimated in 2006, that means about 1.4 million fewer deaths per year. In the continental United States, heat waves in the past decade exceeded the norm by 10 percent, but the number of cold waves fell 75 percent.

Moreover, global warming will mostly increase temperatures during winter, at night and in cold places, making temperature differences less extreme.

It is now eight years since a major hurricane made landfall in the United States.

9:13 am

It is now eight years since a major hurricane made landfall in the United States.

[N]ot a single major hurricane, defined as a Category 3 storm or higher on the Saffir-Simpson scale —with minimum wind gusts of at least 111 mph (178 km/h) — has directly hit the United States in nearly eight years. That’s twice as long as any major hurricane landfall “drought” since 1915, and by far the longest on record since data began being collected prior to 1900. As of today (Sept. 12), it’s been 2,880 days since Hurricane Wilma, the last major hurricane to strike the United States, made landfall on Oct. 24, 2005.

And guess what? The reasons have nothing to do with global warming!

Despite the significant increase in the Arctic icecap’s size this winter, satellite data of the icecap’s actual volume and thickness suggest that the new ice was quite thin.

9:54 am

The uncertainty of science: Despite the significant increase in the size of the Arctic Ocean’s icecap this winter, satellite data of the icecap’s actual volume and thickness suggest that the new ice was quite thin.

Prof Andy Shepherd, from Leeds University, said: “Now that we have three years of data, we can see that some parts of the ice pack have thinned more rapidly than others. At the end of winter, the ice was thinner than usual. Although this summer’s extent will not get near its all-time satellite-era minimum set last year, the very thin winter floes going into the melt season could mean that the summer volume still gets very close to its record low,” he told BBC News.

It is not surprising that the ice was thin, considering that the icecap was recovering from a record low the year before. The scientific question, however, is whether the cap will thicken in the coming years or continue to thin out. That it has recovered somewhat in size might be a onetime jump as the decline continues, or it might be indicative of a new growing trend.

“The face of the sun is nearly blank.”

10:14 am

Today NOAA posted its monthly update of the solar cycle, and as I do every month, I am posting it here, with annotations.

Before we take a look at that, however, there is other climate news that is apropos. The Daily Mail in the UK put out an entertaining article on Saturday with the headline “And now it’s global COOLING! Record return of Arctic ice cap as it grows by 60% in a year.”

The article is entertaining because, after illustrating the ice-cap’s recovery this year, it then notes the 2007 prediction by global warming climate scientists that the Arctic Ocean would be “ice-free” by 2013. If this isn’t a good example of the dangers of crying wolf, I don’t know what is.

I should emphasize that the ice-cap recovery this year does not prove that global warming has ceased. A look at this graph from satellite data shows that even though the Arctic icecap has recovered, it is still remains small when compared to the past few decades. The increase this year might only be a blip, or it could be indicating a new trend. We won’t really know for another five years, if then.

The article is also entertaining because it outlines the confusion that is right now going on behind the scenes at the IPCC. The next IPCC report is scheduled to come out next month, but no one agrees with its conclusions because it apparently ignores or minimizes the approximately fifteen year pause in warming that has now been documented since the late-1990s.

In its draft report, the IPCC says it is ‘95 per cent confident’ that global warming has been caused by humans – up from 90 per cent in 2007. This claim is already hotly disputed. US climate expert Professor Judith Curry said last night: ‘In fact, the uncertainty is getting bigger. It’s now clear the models are way too sensitive to carbon dioxide. I cannot see any basis for the IPCC increasing its confidence level.’ [emphasis mine]

It appears that scientists and governments are demanding approximately 1500 changes to the IPCC draft, which suggests its release will be delayed significantly.

Meanwhile, the Sun continues its lackluster and weak solar maximum.

“The timing couldn’t be worse.”

11:23 pm

The next IPCC report: “The timing couldn’t be worse.”

The author describes how the new report, due out in just a couple of months, is probably already obsolete because of a slew of new papers documenting the long 10 to 15 year pause in global warming that was not predicted by any of the climate models used by the IPCC.

This quote I think sums things up nicely, however:

Due to a ‘combination of errors’, the models have overestimated warming by 100% over the past 20 years and by 400% over the past 15 years.

No Atlantic hurricanes in August for the first time in eleven years.

5:13 pm

More extreme weather, eh? There were no Atlantic hurricanes in August this year, for the first time in eleven years.

As I’ve noted repeatedly, there is no evidence yet of an increase of extreme weather events as predicted by global warming advocates. In fact, some recent data suggests a decline, though I personally wouldn’t take that seriously either.

So, when Al Gore or Barack Obama or Dianne Feinstein starts running around like Chicken Little, claiming the sky is about to fall, remember these facts.
