In the second edition of Climate, History and the Modern World, Hubert Lamb specifically warned of the danger of attributing human causes to natural climate fluctuations. His advice was to continue researching climate and to keep watch on the impacts of change, but not to attribute too much to the idea of the importance of human activity.
Lamb wrote, “In fact, from about the beginning of this century up to 1940 a substantial climatic change was in progress, but it was in a direction which tended to make life easier and to reduce stresses for most activities and most people in most parts of the world. Average temperatures were rising, though without too many hot extremes, and they were rising most of all in the Arctic where the sea ice was receding. Europe enjoyed several decades of near-immunity from severe winters, and the variability of temperature from year to year was reduced. More rainfall was reaching the dry places in the interiors of the great continents (except in the Americas where the lee effect, or ‘rain-shadow’, of the Rocky Mountains and the Andes became more marked as the prevalence of westerly winds in middle latitudes increased).
And the monsoons became more regular in India and west Africa. Planning on the climatic statistics of the preceding decades was in fact allowing wider safety margins for many activities than was apparent up to some time about 1950.”
End of quote.
The following paper confirmed Lamb’s remark by assessing how climate zones changed during the 20th century based on the Koppen classification System modified by Trewartha (KTC)..The relevance of the KTC system is that the temperature and precipitation criteria are based on plant ecology. This subsumes animal ecology because animals depend on plants.
The Belda maps show the climate regions of the world (except Antarctica) for two periods, 1901-1931 and 1975-2005, based on a 30 minute grid, average area about 2500 km2, (About 50,000 grid cells cover 135 million km2, the land area of the Earth except Antarctica.)
Between the two periods separated by 75 years, 8% of the cells changed climate type. When you plot a scatter diagram of distributions for the two periods, you will find there is little divergence from the straight line passing through the origin and with slope unity. R-squared is 99.5.
The paper does not discuss error bars. However, the CRU (UK) has revised the climate data to remove wet bias, an adjustment that would increase R2, indicating even less change than these maps show.
In any other field of Earth science, using data with similar precision, we would claim confirmation of the null hypothesis that the two data sets separated by 75 years are not significantly different.
So yes, the Earth has warmed a little and most people worldwide are better off than their parents and grandparents. The people benefiting the most are those on the margins of steppe to desert and those on the margins between ice and tundra.

I scrolled through the video fast and didn’t see the lie where they claim the Antarctica ice core data of temp and CO2 is proof. In reality, the temperature changes hundreds of years before the CO2 changes, not the other way around

Correct. C02 lags warming, not leads. Alarmists fudged that data to support their agenda.

Tim Ball: You never had any credibility (what, just four obscure climate publications in your entire career?), and you lost even that when you started calling others Nazis on WUWT.

Typical ad hom nonsense from Appell who can’t win an argument on facts.

I give more facts here than anyone. Here are more:
Tim Ball is not a climate science expert, and this has been admitted in a court of law.
After the Calgary Herald published an op-ed by Ball on April 19, 2006, whom the newspaper identified as the first climatology PhD in Canada and a climatology professor at the University of Winnipeg for 28 years, they published a letter on April 23, 2006 from Dr. Dan Johnson, a professor at the University of Lethbridge, who pointed out that neither of those descriptions is true; that Dr. Ball’s credentials were being seriously overstated. Ball later threatened Johnson and the Herald and ultimately sued for defamation.
In their Statement of Defense filed in Court, the Calgary Herald submitted the following:
1. “…that the Plaintiff (Ball) never held a reputation in the scientific community as a noted climatologist and authority on global warming.
2. “The Plaintiff has never published any research in any peer-reviewed scientific journal which addressed the topic of human contributions to greenhouse gas emissions and global warming
3. “The Plaintiff has published no papers on climatology in academically recognized peer-reviewed scientific journals since his retirement as a Professor in 1996;
4. “The Plaintiff’s credentials and credibility as an expert on the issue of global warming have been repeatedly disparaged in the media; and
5. “The Plaintiff is viewed as a paid promoter of the agenda of the oil and gas industry rather than as a practicing scientist.”
Ball dropped his lawsuit.

Looks like Ed has started moderating.
That’s one way to try and win the argument. But never a way that works.
Ed is afraid of views other than his own.

Dear David, You are so quick to criticize people that you overlook truth. You just accused me of moderating or blocking your comment. You are blatantly wrong.
You are very familiar with commenting on WordPress sites. Therefore, you should know standard WordPress settings hold comments with a large number of references for approval by the moderator.
You left a comment with a large number of references at 1:47 pm Sunday. You accused me of blocking your comment at 1:50 pm. The reality is I don’t sit at my computer all day waiting for a comment that WordPress holds for my personal approval. And on Sunday I am usually doing other things. When I reviewed this site at 6:02 pm Sunday, I found your comment waiting my approval, and approved it.
August 21, 2016 at 6:18 pm
David, You criticize everyone. That is the way you attempt to do science. It fails. You criticize Dr. Tim Ball above based upon a record your pulled from The Calgary Herald regarding a Statement of Defense. You are so stupid you do not know that anyone can claim anything in a lawsuit. Such claims are meaningless. The only meaningful information from a court trial is the court decision. In this case, the court made no decision or proclamation or judgment.
I should really remove your claims against Tim Ball because your claims are without basis and inflamatory. But I will give you a chance to respond to this rebuttal to your comment.
Meanwhile, I will bring to the attention of all readers that you, David Appell, have not responded to my request for a reference to your PhD thesis publication. Therefore, I suspect you never did a PhD thesis.
David, please prove you are a real scientist and not an imposter.
August 15, 2016 at 8:44 pm
David, There you go again. Do you really claim to be a scientist? I notice you can never write a scientific rebuttal to papers that show your foolish opinions are wrong. You always resort to an ad hominem attack. Read Aristotle on logic.

Climate change occurred during the planets history many times. But never with this speed and impact as since the late 20th century. And never with such disastrous effects on societies.
It’s not astonishing:
– with 1,2 billion vehicles with fuel engines moving around
– with an average emission of 100 – 400 mg CO2 / vehicle / km
– with 10 thousands of airplanes starting and landing daily
– with industries sending their emissions every second into the atmosphere
– with an industrialized agriculture sending hazardous emissions into the air …
… every day, everywhere in the world … man-made air pollution adds brutally to climate change. And still economists call for economic growth !
If we do not change our way of investment, production and transportation drastically, our children and grand-children will suffer and condemn us not having started the needed change now. And in a relatively short period of time social, economic and natural systems will fail to serve mankind at all.
Do you strive for this? No ? Then please change your mindset first before you continue your business as usual.

Dear Gert, You claim present climate change is faster than ever before. Temperature reconstructions for the last 20,000 to 600,000 years disproves your claim. So your initial statement is wrong.
Please see the graph below of temperature for last 17,000 years by Don Easterbrook. The temperature change in the last 100 years pales in comparison to temperature changes between 15,000 and 10,000 years ago. The red lines show past global warming that far exceed the “speed and impact” of our present global warming.
You list human activities that emit CO2, and you conclude these emissions have caused significant global warming. But, as Soon and others have proved, CO2 is not correlated with temperature. When there is no correlation, there is no cause and effect. Therefore, something besides our CO2 emissions causes temperature change.
Then you make your admonition that we humans must change how we live or our CO2 emissions will cause a disaster.
Your problem is you will not accept real science. Real science is based on hypotheses, predictions, and rejecting all hypotheses that produce false predictions. Watch this 1964 lecture by Richard Feynman.
Your hypothesis that our CO2 causes dramatic global warming or any associated climate change has been proven wrong because its predictions are wrong. Further, data show that CO2 follows temperature rather than temperature following CO2. Cause must precede effect.
You promote a belief that science has proven to be wrong. Therefore, you promote a false religion.
You promote actions to “address” global warming that cause more harm to more people than doing nothing. You propose actions that cause far more economic and social damage than our CO2 emissions ever will.

I didn’t know central Greenland was the whole world.

The link between anthropogenic C02 emissions and climate change is so weak, and scientific evidence that C02 has anything to do with the weather is non existant. It is the big multi hundred billion dollar scam. I have been searching for the evidence ever since Maurice Strong uttered the first climate lies in the UN. C02 is harmless plant food. The real greenhouse gas which has kept our planet’s temperature regulated nicely for billions of years is water vapour. Tough to get grant money from governments based on trying to scare people with water, but I’m sure Trudeau, McKenna, Phillips, Soros, Clintons and Gore would hand it over by the billions in return for scientific papers which support their anti industry agendas if they could blame the worlds problems on man made water vapour.
