A Day Of Extremes

While Australia was sizzling through a heatwave yesterday, which may or may not have set some records- some of which are up to 20 years old- it was actually snowing in the Sahara Desert.

For more on the snowy Sahara (the second year in a row it snowed there) click here. Jo Nova has the details about why the Sydney heat “record” is less than impressive.

In Narrabri we have the regular “Narrabri Airport sets new record” fairly often because they moved the official weather station from Narrabri West P.O. about 20 years ago,

I think the Bureau of Meteorology needs to stop being a publicity channel for “climate change” and go back to its roots in science- the old variety of trying to be objective as opposed to post-modern, post-truth “science”.

Another “Green”Hare-brain Scheme

The ABC is breathlessly reporting that London busses may soon be powered by waste coffee grounds. This is a relief to those who also bought the story about global warming, if unchecked, could reduce the area suitable for coffee cultivation.

So here’s the plan. You go to all those coffee shops around London, scrounge their bin for a litre or two of waste, take it to the factory, refine it and there you have it- “bio-diesel” for your bus fleet.

Here is the problem. You have a choice of a product that is low and variable quality and distributed in small quantities over a large area which then  has to be refined in a small scale facility and then sent to the bus fuel station. Or you could use a product of known and standardised quality, produced in huge quantities through known processes and with already established distribution facilities.

It’s not hard to work out which is going to win hands down.

I started to try to work out a rough estimate of costs but there isn’t enough information to go on. I suspect that residents of London will end up paying more in the name of saving the planet, with no real guarantee that they are reducing CO2 emissions which is given as the aim of the process.

Amazing: Plants Adapting to Increased CO2

The CSIRO has found that plants around the world are absorbing more CO2 and doing it more efficiently than ever before. As the concentration of CO2 rises in the atmosphere all kinds of plants are growing faster, but using relatively less water to do so.

This confirms the satellite images showing that the world is greening.

Rising carbon dioxide is making the world’s plants more water-wise

Land plants are absorbing 17% more carbon dioxide from the atmosphere now than 30 years ago, our research published today shows. Equally extraordinarily, our study also shows that the vegetation is hardly using any extra water to do it, suggesting that global change is causing the world’s plants to grow in a more water-efficient way.

Water is the most precious resource needed for plants to grow, and our research suggests that vegetation is becoming much better at using it in a world in which CO₂ levels continue to rise.

The ratio of carbon uptake to water loss by ecosystems is what we call “water use efficiency”, and it is one of the most important variables when studying these ecosystems.

Our confirmation of a global trend of increasing water use efficiency is a rare piece of good news when it comes to the consequences of global environmental change. It will strengthen plants’ vital role as global carbon sinks, improve food production, and might boost water availability for the well-being of society and the natural world.

Mainstream Climate Scientists Discover a Pause in Global Warming Ten Years After “Deniers”

Anyone who gets their news from anywhere other than ABC and Fairfax would be aware that global temperatures were flat for the last 20 years. Of course the activists were decrying “The Pause” as a lie of big oil or Trump or whatever. The computer models failed to predict The Pause so warming must be continuing and they chose to believe the models rather than the measured facts. And of course they continued to call disbelievers “deniers” and heretics.

 

But now the climate science team are starting to acknowledge The Pause and admit that perhaps hteir models are perhaps less than perfect. Amazing! Garbage In- Garbage Out even applies to climate models.

The New ‘Consensus’ On Global Warming – a shocking admission by “Team Climate”

 

By MICHAEL BASTASCH AND DR. RYAN MAUE

A scientific consensus has emerged among top mainstream climate scientists that “skeptics” or “lukewarmers” were not long ago derided for suggesting — there was a nearly two-decade long “hiatus” in global warming that climate models failed to accurately predict or replicate.Anew paper, led by climate scientist Benjamin Santer, adds to the ever-expanding volume of “hiatus” literature embracing popular arguments advanced by skeptics, and even uses satellite temperature datasets to show reduced atmospheric warming.

More importantly, the paper discusses the failure of climate models to predict or replicate the “slowdown” in early 21st century global temperatures, which was another oft-derided skeptic observation.

“In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble,” reads the abstract of Santer’s paper, which was published Monday.

“Over most of the early twenty-first century, however, model tropospheric warming is substantially larger than observed,” reads the abstract, adding that “model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.”

The paper caught some prominent critics of global climate models by surprise. Dr. Roger Pielke, Sr.tweeted “WOW!” after he read the abstract, which concedes “model tropospheric warming is substantially larger than observed” for most of the early 21st Century.

It’s more than a little shocking.

Hal G.P. Colebatch: The prophets of eco-doom: a perfect record of failure

CULTURAL HISTORY
The prophets of eco-doom: a perfect record of failure

by Hal G.P. Colebatch

News Weekly, June 3, 2017

Environmentalism, or at least its deep-green variety, has, by the clownishly failed predictions of its gurus and prophets, confirmed its place as a leader among those “sciences” in which a complete lack of factual accuracy bears not the slightest relationship to its proponents’ reputations or careers.

“Earth Day” was conceived 47 years ago, time enough for any catastrophic threats to the Earth forecast then to have materialised. At that time the late George Wald, a Nobel Laureate and professor of Biology at Harvard, predicted: “Civilisation will end within 15 or 30 years unless immediate action is taken against problems facing mankind.”

It didn’t.

The problems facing civilisation come chiefly from uncivilised men who denude landscapes by chopping down trees for fuel. Civilised men have available safe, clean nuclear energy, and if they live in a country like Australia, the means to quiet superstitious fears by building reactors in deserts.

At the same time as Professor Wald’s predictions of universal doom, Professor Paul Ehrlich of Stanford University boosted his bank account with the best seller, The Population Bomb. This declared that the world’s population would soon outstrip food supplies. He stated that the “battle to feed humanity” was lost. In 1969 he told Britain’s Institute of Biology: “If I were a gambler, I would take even money that England will not exist in the year 2000.”

The ludicrous nature of this doom mongering, looked back at from 2017, should speak for itself. Ehrlich was peddling a sort of doom pornography.

If anyone had taken it seriously, rather than as a subject for a cheap thrill, they would have been laying down stocks of food, guns and ammunition, and, like some American “survivalists” (whose fears came from a different direction), preparing refuges in the Outback against the coming Armageddon. On that first Earth Day, Ehrlich warned: “In 10 years, all important animal life in the sea will be extinct.”

Instead of being sacked from his chair, or being offered a job as a circus clown, since then, showing the limitless human appetite for flim-flam, Ehrlich has won no fewer than 16 awards, including the 1990 Crafoord Prize, the Royal Swedish Academy of Sciences’ highest award. As that well-known social philosopher Charles Manson put it: “You can convince anyone of anything if you push it to them all the time.”

In an article for The Progressive, Ehrlich predicted: “The death rate will increase until at least 100-200 million people per year will be starving to death during the next 10 years.”

Of course, the first influential proponent of ecological doom was Thomas Malthus, the first edition of whose Essay on the Principle of Population was published in 1798. Neither Malthus nor Karl Marx, with the Theory of Increasing Misery, foresaw that improved agricultural and industrial production and technology would lead to the Earth being able to support populations many times larger and at a much higher level than they imagined.

Thus, with the “green revolution” allowing at least countries with good governments to feed themselves, a new hobgoblin was called for. How many of us remember that in the 1970s the existential threat hanging over mankind was not global warming but global cooling?

In International Wildlife of July 1975, one Nigel Calder warned: “The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind.” In Science News the same year, C.C. Wallen of the World Meteorological Organisation is reported as saying: “The cooling since 1940 has been large enough and consistent enough that it will not soon be reversed.”

In 2000, climate researcher David Viner told The Independent that within “a few years”, snowfalls would become “a very rare and exciting event” in Britain. “Children just aren’t going to know what snow is,” he said. “Snowfalls are now just a thing of the past.” In the following years, Britain saw some of its largest snowfalls and lowest temperatures since records started being kept in 1914.

In 1970, ecologist Kenneth Watt told a Swarthmore College audience: “The world has been chilling sharply for about 20 years. If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990 but 11 degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.”

2000 has come and gone, and there is no ice age in sight.

Also in 1970, Senator Gaylord Nelson wrote in Look magazine: “Dr S. Dillon Ripley, secretary of the Smithsonian, believes that in 25 years [ie, by 1995], somewhere between 75 and 80 per cent of all the species of living animals will be extinct.”

A chart in Scientific American that year estimated that mankind would run out of copper shortly after 2000. Lead, zinc, tin, gold and silver would disappear before 1990. In 1974 the U.S. Geological Survey said that the U.S. had only a 10-year supply of natural gas.

Hurricane Drought Continues in USA

Despite the alarmist squeals of the climate change crowd that the frequency of “extreme weather events” (one of those very vague terms that the very unscientific boosters of man-made climate change like to use to hide the fact that they are telling porkies), the US is undergoing a very large hurricane drought that has lasted for 4001 days- almost 11 years.

The Greens will be all over Hurricane Michael when or if it lands in Florida and say it is evidence of man-made climate change and we must act now, as if this is the first ever category 3 storm to hit America.

The fact is that the southern parts of the USA like the northern parts of Australia have historically been subject to regular tropical storms- called cyclones in Australia, hurricanes in the USA.

Here is a graph that looks at the 78 hurricanes to hit the US since 1900. For each one (labelled 1 to 78) on the horizontal axis, the graph shows the days between that storm and its predecessor. The red line shows an estimated “trend” line, although I am not sure that on this type of graph that is very helpful, especially as we do not yet know if this latest “drought” will be followed by a dozen storms in quick succession.

If there is any statistical link between temperature, CO2 and storm occurrences I think it is clear that rising temperatures are associated with fewer storms not more.

Another “Climate Science” Fail”- The Grolar Bear

A couple of months ago the ABC was all over the claim that declining Arctic ice due to “climate change” was causing polar bears to have more encounters with their grizzly cousins and that more hybrids were being seen. It turns out that the alleged “grolars”  were just blond grizzlies. Let’s not let the facts get in the way of the climate doom narrative.

From WUWT:

The unbearable lightness of polar bear ‘climate science’

From the “Emily Litella” department (never mind) and Zoologist Dr. Susan Crockford, comes yet another hilarious take-down of attempts to link polar bears and climate change last month. Turns out it’s just a blonde. Paging Andrew Derocher! Cleanup on aisle 5!

Dr. Crockford writes:

All the hubris last month about polar bear x grizzly hybrids, based on an unusual-looking bear killed near Arviat, has turned out to bewishful thinkingby those who’d like to blame everything to do with polar bears on climate change. An awful lot of “experts” now have egg on their faces.That “hybrid” was just a blonde grizzly, as I warned it might.
