'First, the non-climatic effects of carbon dioxide are dominant over the climatic effects and are overwhelmingly beneficial. Second, the climatic effects observed in the real world are much less damaging than the effects predicted by the climate models, and have also been frequently beneficial.'

Straight Fs for the IPCC at Mother Nature's School of Climate Modelling

As the teacher's 'Notes' state, the climate models relied on by the IPCC 'show no skill' when it comes to the processes that dictate temperature and precipitation.  In other words, they add nothing at all when it comes to forecasting.

'Climate Models FAIL' is the title of a new book by Bob Tisdale, one which is aimed at a wide range of readers, and in particular those who may be unfamiliar with technicalities:

'Climate Models Fail is intended for readers without technical or scientific backgrounds. There are introductory chapters that provide basic information.'

and

'Climate Models Fail has been proofread and edited by someone without a technical background. She has taken the content of this book, originally written in my technical/scientific style, and made it much easier to read and understand, while leaving the content intact.'




A preview pdf is available here: http://bobtisdale.files.wordpress.com/2013/09/preview-climate-models-fail.pdf  The two quotes shown in italics are from this preview, as is this one summarising some of the hopes and fears of the author:

'Growth in climate science has been stunted by the IPCC’s politically-driven addiction to conjectures about anthropogenic climate change. Decades after it began, climate science is still in its infancy. Yet, it is portrayed as a well-established, noble, bastion of solid research, the flawless jewel of Earth sciences that can do no wrong. Worse, climate science has been ruthlessly exploited by environmental groups and politicians and even by many of the scientists themselves. 
The primary obstacles for the climate science community in the years and decades to come are: (1) the expectations of government funding agencies, which are obviously tied to political agendas; and (2) the anchoring effect of the fanatical beliefs of those members whose careers and funding skyrocketed as a result of their drum beating for the IPCC.
The people of the world rely on the findings of the climate science community, and in order for climate science to move forward, that community will have to be honest within itself and with the public. Hopefully, that will occur in my lifetime, but I’m not holding my breath.'

The book can be bought as a pdf ($9.99) (here) or as a file for Kindle ($10.29) (here).

I wonder if the 'people of the world' will trust the climate science community much longer?  Or will that 'community' be assigned to the dustbin of history where the IPCC itself belongs?  Donna Laframboise has studied the IPCC's behaviour and contrasted it with their claims and aspirations, and has found such large discrepancies that her two books on it justify their provocative titles 'The Delinquent Teenager', and 'Into the Dustbin'.  Read them to be convinced, like I was, that the IPCC is not to be trusted.  I have not yet read Bob Tisdale's new book, but it sure looks like it will not serve to improve my view of that organisation and those scientists who have actively supported the sorry saga of alarm over CO2 that it was formed to promote.  An alarm for which computer models of climate have provided the mainstay.  The very same computer models that FAIL according to Tisdale, and according to anyone else who chooses to compare their predictions with the observations.

'Climate Change Reconsidered II': a more realistic appraisal than the IPCC will ever be able to provide

Teachers wanting to dig more deeply into the study of climate variation have a new resource available for free download: the latest NIPCC reports entitled 'Climate Change Reconsidered II'.

Unlike the faith-based tone of the IPCC reports, in which marshalling of evidence to buttress their heartfelt and walletfelt beliefs in CO2 as a major driver of climate variation dominate, the NIPCC is free to be more scientific.  That means being sceptical of high-blown claims, being on guard against superficial reasoning, and ready to share counter-examples and failings of current models and theories.  The frontiers of science are usually ragged and untidy, and the genuine scientist working there should be willing to follow leads and go where the data takes them.  Their job is not to construct palaces in the sky that happen to suit powerful political and financial interests.  Their job is not to provide a front of respectability for the disgraceful campaigns of scaremongering that have suited so many individual and organisations in recent decades.  Their job is to speculate, to dig into the data, to entertain theories in an objective, semi-detached manner, and to seek new ideas and new observations that look the most promising for clarifying our understanding.  But when so many politicians have been misled, or are being misleading, about what is known about the causes of climate variation, some scientists will feel duty-bound to draw their attention to a broader view, and to contrary evidence.  Here is how they see themselves:

'The Red Team Reports 
A technique frequently used in industry, government, and law when dealing with complex or controversial matters is to deploy competing Green and Red Teams to pursue alternative approaches (e.g., Sandoz, 2001; Nemeth et al.,2001). A Red Team provides a kind of “defense counsel” to verify and counter arguments mounted by the initial Green Team (the “prosecution”) as well as discover and present alternatives the Green Team may have overlooked. 
 For many years, one team has dominated the global debate over climate change, the Green Team of the United Nations’ Intergovernmental Panel on Climate Change (IPCC). In 2003, however, at a meeting in Milan, a Red Team started to emerge composed of independent scientists drawn from universities and private institutions around the world. Since 2008 that team, the Nongovernmental International Panel on Climate Change (NIPCC), has been independently evaluating the impacts of rising atmospheric concentrations of CO2 on Earth’s biosphere and evaluating forecasts of future climate effects (Singer, 2008; Idso and Singer, 2009; Idso, Carter, and Singer, 2011).'

Here are their main conclusions as presented in Figure 1 of the Summary for Policy Makers:

'• Atmospheric carbon dioxide (CO2) is a mild greenhouse gas that exerts a diminishing warming 
effect as its concentration increases. 
• Doubling the concentration of atmospheric CO2 from its pre-industrial level, in the absence of 
other forcings and feedbacks, would likely cause a warming of ~0.3 to 1.1°C, almost 50% of 
which must already have occurred. 
• A few tenths of a degree of additional warming, should it occur, would not represent a climate 
crisis. 
• Model outputs published in successive IPCC reports since 1990 project a doubling of CO2 could 
cause warming of up to 6°C by 2100. Instead, global warming ceased around the end of the 
twentieth century and was followed (since 1997) by 16 years of stable temperature. 
• Over recent geological time, Earth’s temperature has fluctuated naturally between about +4°C 
and -6°C with respect to twentieth century temperature. A warming of 2°C above today, should it 
occur, falls within the bounds of natural variability. 
• Though a future warming of 2°C would cause geographically varied ecological responses, no 
evidence exists that those changes would be net harmful to the global environment or to human 
well-being. 
• At the current level of ~400 ppm we still live in a CO2-starved world. Atmospheric levels 15 times 
greater existed during the Cambrian Period (about 550 million years ago) without known adverse 
effects. 
• The overall warming since about 1860 corresponds to a recovery from the Little Ice Age 
modulated by natural multi-decadal cycles driven by ocean-atmosphere oscillations, or by solar 
variations at the de Vries (~208 year) and Gleissberg (~80 year) and shorter periodicities. 
• Earth has not warmed significantly for the past 16 years despite an 8% increase in atmospheric 
CO2, which represents 34% of all extra CO2 added to the atmosphere since the start of the 
industrial revolution. 
• CO2 is a vital nutrient used by plants in photosynthesis. Increasing CO2 in the atmosphere 
“greens” the planet and helps feed the growing human population. 
• No close correlation exists between temperature variation over the past 150 years and human-related CO2 emissions. The parallelism of temperature and CO2 increase between about 1980 
and 2000 AD could be due to chance and does not necessarily indicate causation. 
• The causes of historic global warming remain uncertain, but significant correlations exist between 
climate patterning and multi-decadal variation and solar activity over the past few hundred years. 
• Forward projections of solar cyclicity imply the next few decades may be marked by global 
cooling rather than warming, despite continuing CO2 emissions.

'Oh no! The Snow!' Cool Athletes Tell Kids about their Hot Planet - Snow Getting Harder to Find Say Some.

The article headlined on the left appeared in Sports Illustrated for Kids, SIKids, in June this year.

Here is the sort of thing they are doing:

"Protect Our Winters partners with The North Face and Alliance For Climate Education to visit schools through their Hot Planet/Cool Athletes program. Protect Our Winters educates students about the issue, using an interactive presentation with stories from professional winter athletes to inspire kids to make a difference. Jones says that paying attention to little things in your day-to-day life can help the environment, too. For example, he limits his "carbon footprint" by buying locally grown food. And instead of using snowmobiles and helicopters to get up mountains, he hikes for his snowboarding adventures. "This is the planet you are inheriting" Jones says."

It seems that Jones had a bit of an epiphany: "After seeing resorts closed and areas that once had great jumps for snowboarding shut down due to insufficient snowfall, Jones realized that climate change was a crisis that needed to be addressed."

Here's another one featured in the article sharing her wisdom with the young:

"Gleich says that she's seen how climate change can pose an immediate danger to winter athletes. Over the past two winters, Utah has seen a lot less snow, making the snow pack lower. In turn, this makes mountains more prone to dangerous — and sometimes deadly — avalanches. Additionally, with less snow, there are more rocks that could injure skiers.
Avoiding the hazardous areas has also taken away some of the fun of the sport. "When you don't have that snow pack, you can't ski the rad peaks you want to ski," Gleich says. "It's a bummer to have to stay on the smaller mountains."

Now, here is some data for 1972 to 2016:

Notice the variability in snow extent. Notice the lack of any dramatic trend.  Notice the simple straight-line fit is rising gently.  [the original chart here was not appearing, and has been replaced by the one shown, copies from http://www.climate4you.com/ - JS, 8 Mar 17]

I hope that some day, somewhere, a child in some school targeted for one of these Hot Planet/Cool Athletes extravaganzas will circulate this sort of chart ahead of the visitors arriving with their propaganda kits.

Once again, a look at the data is enough.

Inch by inch, row by row
We can make the rascals go
All it takes is to look, don't you know
For their claims are so unsound.

(to the tune of the Garden Song)

Note added 17 April 2014.  Much of North America has been enduring a very cold winter, with record levels of snow.  According to this report, for example, 5 of the snowiest winters on record in Detroit have occurred in the last 11 years: http://notrickszone.com/2014/04/16/bastardi-detroit-sets-all-time-record-snowy-winter-5-of-the-snowiest-winters-occurred-in-last-11-years/
