Finnish Study Finds ‘Practically No’ Evidence for Man-Made Climate Change - Japanese Study Confirms

A new study conducted by a Finnish research team has found little evidence to support the idea of man-made climate change. The results of the study were soon corroborated by researchers in Japan.

In a paper published late last month, entitled ‘No experimental evidence for the significant anthropogenic climate change’, a team of scientists at Turku University in Finland determined that current climate models fail to take into account the effects of cloud coverage on global temperatures, causing them to overestimate the impact of human-generated greenhouse gasses.

Models used by official bodies such as the Intergovernmental Panel on Climate Change (IPCC) “cannot compute correctly the natural component included in the observed global temperature,” the study said, adding that “a strong negative feedback of the clouds is missing” in the models.

Adjusting for the cloud coverage factor and accounting for greenhouse gas emissions, the researchers found that mankind is simply not having much of an effect on the Earth’s temperature.

If we pay attention to the fact that only a small part of the increased CO2 concentration is anthropogenic, we have to recognize that the anthropogenic climate change does not exist in practice.

The study’s authors make a hard distinction between the type of model favored by climate scientists at the IPCC and genuine evidence, stating “We do not consider computational results as experimental evidence,” noting that the models often yield contradictory conclusions.

And yet, so many 'scientists' do consider computer models to be evidence, when really they are mostly the imagination of the model's creator. And they are almost always wrong. So why are they accepted as evidence?

Given the evidence presented in the study, the Finnish team rounded out the paper by concluding “we have practically no anthropogenic climate change,” adding that “the low clouds control mainly the global temperature.”

The results sharply cut against claims put forward by many environmentalists, including US lawmakers such as Alexandria Ocasio-Cortez, who argue not only that climate change is an immediate threat to the planet, but that it is largely a man-made phenomenon. Ocasio-Cortez, better known as ‘AOC’, has proposed a ‘Green New Deal’ to address the supposedly dire threat.

Japanese researchers at the University of Kobe arrived at similar results as the Turku team, finding in a paper published in early July that cloud coverage may create an “umbrella effect” that could alter temperatures in ways not captured by current modeling.

Hundreds of Scientists Urge Trump to Withdraw from U.N. Climate-Change Agency

MIT’s Richard Lindzen says policies cause economic harm with ‘no environmental benefits’

By Valerie Richardson - The Washington Times 

More than 300 scientists have urged President Trump to withdraw from the U.N.’s climate change agency, warning that its push to curtail carbon dioxide threatens to exacerbate poverty without improving the environment.

In a Thursday letter to the president, MIT professor emeritus Richard Lindzen called on the United States and other nations to “change course on an outdated international agreement that targets minor greenhouse gases,” starting with carbon dioxide.

“Since 2009, the US and other governments have undertaken actions with respect to global climate that are not scientifically justified and that already have, and will continue to cause serious social and economic harm — with no environmental benefits,” said Mr. Lindzen, a prominent atmospheric physicist.

Signers of the attached petition include the U.S. and international atmospheric scientists, meteorologists, physicists, professors and others taking issue with the United Nations Framework Convention on Climate Change [UNFCCC], which was formed in 1992 to combat “dangerous” climate change.

In 1990, the IPCC predicted a 1 degree C rise in the global temperature by 2025. It is now 2017 and we have seen about a quarter of a degree rise in temperature. Until they get the science right we should not be spending extreme amounts of money to fix a problem that is greatly exaggerated. Alleviate the poverty in the world; stop the selling of weapons as a center-piece of western economies. The worst problem in the world is child sex abuse - by a long shot. Tens of millions of children are sexually abused before they turn 18. Do something about that!

The 2016 Paris climate accord, which sets nonbinding emissions goals for nations, was drawn up under the auspices of the UNFCCC.

“Observations since the UNFCCC was written 25 years ago show that warming from increased atmospheric CO2 will be benign — much less than initial model predictions,” says the petition.

And certainly not worth the trillions of dollars those lunatics want to spend on it.

Scientist Accused of ’Crying Wolf’ on Climate Change with Claim that Arctic Sea Ice Would Vanish

Dire predictions that the Arctic would be free of sea ice by September have proven unfounded after satellite images showed there is far more ice now than in 2012.

Scientists including Peter Wadhams, of Cambridge University, and Wieslaw Maslowski, of the Naval Postgraduate School in Moderey, California, have regularly forecast the loss of ice by 2016, a warning that has been widely reported by the BBC and other media outlets.

Prof Wadhams, who is considered a leading expert on Arctic sea ice loss, has recently published a book entitled A Farewell To Ice in which he repeated the assertion that the Arctic would be free of ice in the middle of this decade.

As late as this summer he was still predicting an ice-free September.

Yet when figures were released for the yearly minimum on Sept 10, they showed that there was still 4.14 million sq km of sea ice, which was 21 per cent more than the lowest point in 2012.

For the month of September overall there was 31 per cent more ice than in 2012, figures released this week by the National Snow and Ice Data Centre (NSIDC) show, amounting to an extra 1.09 million sq km of sea ice.

Although NSIDC satellite data going back to 1981 show an undeniable downward trend in sea ice over the past 35 years, scientists have accused Prof Wadhams and others of “crying wolf” and harming the message of climate change through “dramatic”, “incorrect” and “confusing” predictions.

Dr Ed Hawkins, associate professor in the department of meteorology at the University of Reading, said: “There has been one prominent scientist who has regularly made more dramatic, and incorrect, in my view predictions suggesting that we would by now be in ice-free conditions.

“There are very serious risks from continued climatic changes and a melting Arctic but we do not serve the public and policy-makers well by exaggerating those risks.

“We will soon see an ice-free summer in the Arctic but there is a real danger of ’crying wolf’ and that does not help anyone.

“As global temperatures rise we will see a continuing decline in Arctic sea ice extent, although this will happen somewhat erratically, rather like a ball bouncing down a bumpy hill.

“Without substantial reductions in greenhouse gas emissions, the ball will reach the bottom of the hill, meaning the Arctic is ’ice-free,’ starting with a few days one summer, a few weeks another summer and gradually becoming more and more frequent.”

It is the latest example of experts making alarming predictions which do not come to pass. Earlier this week environmentalists were accused of misleading the public about the “Great Pacific Garbage Patch” after aerial shots proved there was no “island of rubbish” in the middle of the ocean.

Likewise, warnings that the hole in the ozone layer would never close were debunked in June.

Note: I have not checked out either of these claims, but will do so soon. I hope.

Scientists said that such claims risked detracting from the real issue.

Losing Arctic sea ice is a major problem because ice reflects 85 per cent of sunlight while open water reflects just seven per cent, meaning the rest is absorbed by the planet, which speeds up global warming. A massive melt of freshwater could also disrupt global ocean currents, and change weather systems.

I suspect that in the high Arctic, the sun is at such a low angle that a lot more than 7% of sunlight is reflected from water, a lot more!

For more than a decade most scientists have accepted that the Arctic will be free of ice by 2050, while the Intergovernmental Panel on Climate Change (IPCC) calculates there is a 66 per cent chance of no ice by the middle of the century if emissions continue to increase annually.

Yet in 2007 Prof Wadhams predicted that sea ice would be lost by 2013 after levels fell 27 per cent in a single year.

By 2013 ice levels were actually 25 per cent higher than they had been six years before. In 2012, following another record low Prof Wadhams changed his prediction to 2016.

The view was supported by Prof Maslowski who in 2013 published a paper in the Annual Review of Earth and Planetary Sciences also claiming that the Arctic would be ice-free by 2016, plus or minus three years.


La Nina at work, already

Instead of record lows, this year the Arctic has seen the quickest refreeze on record with the extent of sea ice growing 1.05 million sq km in just three weeks since the Sept 10 minimum. The Danish Meteorological Institute said that refreezing was happening at the fastest rate since its daily records began in 1987.

Thank you, La Nina! I'm sure the Arctic will recover a lot of ice cover this winter.

Andrew Shepherd, professor of earth observation at University College London, said that there was now “overwhelming consensus” that the Arctic would be free of ice within the next few decades, but warned that earlier predictions were based on poor extrapolation.

“A decade or so ago, climate models often failed to reproduce the decline in Arctic sea ice extent revealed by satellite observations,” he said.

“One upshot of this was that outlier predictions based on extrapolation alone were able to receive wide publicity. But climate models have improved considerably since then, and they now do a much better job of simulating historical events.

Is that really true? Or have the models been adjusted to predict a more desirable outcome? You can see I'm a bit cynical.

“This means we have greater confidence in their predictive skill, and the overwhelming consensus within the scientific community is that the Arctic Ocean will be effectively free of sea ice in a couple of decades should the present rate of decline continue.”

Prof Myles Allen, of Oxford University, added: “The Arctic was only predicted to be close to ice-free in September by mid-century.”

Scientists said it was clear that sea ice was shrinking but there were large fluctuations between years. For example 2013 showed a 50 per cent increase from the previous year.

Prof Jonathan Bamber, of the University of Bristol, said: “This year’s low was the second lowest on record and not as low as 2012 but there is always variability in any part of the climate system so you would not expect a monotonic decline year on year, whatever was going on.

Nevertheless, this was 4 more years of global warming and the strongest El Nino ever. It certainly seems odd that this would not be the year of the greatest sea ice minimum. Or perhaps we are missing something here?


Sea ice decline may not be man-made

“The signal of Arctic sea ice decline is possibly the clearest we have of climate change. That does not mean, by definition, it is man-made but there is no question that sea ice volume has been declining, on average, over the past 40 years and that all the indications from climate data, satellite observations etc. are that the decline will continue.”

Bob Ward, of the Grantham Institute on Climate Change and the Environment, added: “Peter Wadhams has made predictions of the imminent disappearance of summer Arctic sea ice, which have not been fulfilled, but the evidence still shows a rapid decline.

“The trend in Arctic sea ice extent is definitely downwards for every single month of the year. The most recent IPCC forecast is that the Arctic has up to a 66 per cent chance of being ice-free in September by 2050 for the highest emissions scenario.”

Speaking to The Daily Telegraph, Prof Wadhams accepted that sea ice decline had not happened as quickly as he had predicted. However, he still believes that an ice-free Arctic is still only a “very small number of years” away.

“My view is that the trend of summer sea ice volume is relentlessly downward, such that the volume (and thus area) will come to a low value very soon – in a very small number of years,”

He said. “This is to be contrasted with some of the bizarre predictions made by computer modellers, who have the summer sea ice remaining until late this century, which is quite impossible.”

I think I prefer the bizarre modellers. In "Global Warming - Getting Off the Fence (Updated)", I predict a global temperature rise of only 0.5 to 0.75 degrees by the end of this century. And that may be an overestimate.

I don't mind being lumped in with those who are called 'bizarre', especially since those doing the calling have been consistently wrong.
