Earth and climate – an ongoing controversy


But the researchers are still hooked on the unlikely idea that trace gases alone can ‘determine’ variations in global temperatures, despite lack of correlation in the data and poor results from climate model ‘projections’.

Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions, reports Phys.org.

A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature.

“Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter.

Claims that everywhere apart from the Eastern USA was warmer than ‘normal’ this winter turn out to be wide of the mark, in parts of Siberia at least.

The thermometer in a remote Siberian village known as the coldest inhabited place on earth has broken as temperatures plunged to near-record depths, reports the Daily Telegraph.

The public device, which was installed in Oymyakon as a tourist attraction, recorded -62C, before malfunctioning this week.

Meanwhile the Siberian Times reports that some locals had readings as low as -67C – in touching distance of the record -67.7C, which was logged in the village in February 1933.

Arctic Ocean


The researchers believe Saharan air reaching the Arctic was a rare but significant factor in an unusual warming event two years ago.

In the winter of 2015/16, something happened that had never before been seen on this scale: at the end of December, temperatures rose above zero degrees Celsius for several days in parts of the Arctic, reports Phys.org. Temperatures of up to eight degrees were registered north of Svalbard.

Temperatures this high have not been recorded in the winter half of the year since the beginning of systematic measurements at the end of the 1970s. As a result of this unusual warmth, the sea ice began to melt.

White winter in the USA


Battered by the bomb cyclone which brought heavy snow and flooding to a swathe of the US, America is facing the threat of the big chill says the Daily Telegraph.

As workers started shovelling away the mountain of snow, temperatures started plunging.

They plummeted to as low as -20C (-4F) in many parts of New England. In Caribou, northern Maine, the wind chill was poised to bring the reading down to -40C (-40F).

According to the National Weather Service, the lowest temperature on Friday, -41C (-42F), was recorded at Embarrass, Minnesota. On the summit of Mount Washington in New Hampshire, forecasters expect the biting winds to make it feel as if it was -100F (-70C).

Geoscientist Jeff Severinghaus said: “Our precision is about 0.2 ºC (0.4 ºF) now, and the warming of the past 50 years is only about 0.1 ºC,” adding that advanced equipment can provide more precise measurements, allowing scientists to use this technique to track the current warming trend in the world’s oceans, reports Phys.org. Quite modest recent warming then?

There’s a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego.

In an article published in the Jan. 4, 2018, issue of the journal Nature, geoscientist Jeff Severinghaus and colleagues at Scripps Oceanography and institutions in Switzerland and Japan detailed their ground-breaking approach.

This is an opinion piece, a sort of alarmism-in-reverse, and no-one can be sure that any given weather or climate forecast will prove to be accurate or even on the right lines, but the arguments are here to consider. Numerous climate researchers do expect the solar slowdown to push average temperatures lower for at least a decade or two. Others think 0.04% carbon dioxide in the atmosphere will counter all that.

The danger from the Global Warming crowd is that they are misleading the entire world and preventing us from what is dangerously unfolding that sparks the rapid decline in civilization – GLOBAL COOLING, says Martin Armstrong at Armstrong Economics.

I previously warned that this is not my opinion, but simply our computer. If it were really conscious it would be running to store to buy heating pads. This year will be much colder  for Europe than the last three. It will also be cold in the USA.

We are in a global cooling period and all the data we have in our computer system warns that the earth is turning cold not warm.

Snow disruption in the USA, December 2017 [credit: BBC]


Climate contortionists must be working overtime to explain how this could fit into their models showing ever milder northern winters under supposedly dire man-made warming.

Bitter cold continues to blanket the northern United States and Canada as forecasters warn that the deep freeze will continue into the start of 2018, reports BBC News.

International Falls in the US state of Minnesota – the self-proclaimed “Icebox of the Nation” – saw temperatures drop to -37F (-38.3C).

New Hampshire’s Mount Washington, home of the “worst weather in the world”, set a new low record at -34F (-36.6C).

Parts of Canada are colder than the North Pole or Mars, officials say.

Forecaster highlights the jetstream over the UK [image credit: BBC]


It’s more predictable than we thought, they say – at least in some ways. The test of time awaits.

Researchers in the UK have developed a method of improving the long range accuracy of summer weather in the UK and Europe, says the BBC.

The scientists found a connection between sea surface temperatures in the North Atlantic in March and April and the subsequent summer’s rain or shine.

The researchers say the new method may benefit agriculture, tourism and construction.

The caption to the explanatory video says: ‘When scientists look at Jupiter’s upper atmosphere in infrared light, they see the region above the equator heating and cooling over a roughly four-year cycle’.

Speeding through the atmosphere high above Jupiter’s equator is an east-west jet stream that reverses course on a schedule almost as predictable as a Tokyo train’s, says Phys.org. Now, a NASA-led team has identified which type of wave forces this jet to change direction.

Similar equatorial jet streams have been identified on Saturn and on Earth, where a rare disruption of the usual wind pattern complicated weather forecasts in early 2016.

The new study combines modeling of Jupiter’s atmosphere with detailed observations made over the course of five years from NASA’s Infrared Telescope Facility, or IRTF, in Hawai’i. The findings could help scientists better understand the dynamic atmosphere of Jupiter and other planets, including those beyond our solar system.

As the report concludes: ‘Both global warming and carbon dioxide have benefitted plant growth, and both are important contributors to the success of modern civilization.’

Global cereal (grain) production has reached record levels in 2017, says The GWPF.

Credit for the increase usually goes to agrochemicals and other advanced agricultural technology. However, there are two other key contributors — carbon dioxide and climate change.

World cereal production for 2017 is projected to reach 2,613.3 million tons, 5.8 million tons above 2016’s level and nearly one-fourth higher than 2008’s. Despite population growth, production per capita rose 13 percent over the last decade, from 0.31 to 0.35 tons per person.

Earth and climate – an ongoing controversy


It turns out that the temperature target of the agreement was never properly defined.

New study puts the 1.5°C and 2.0°C temperature limits of the Paris Agreement into a historical climate context, says The GWPF.

The Paris Agreement adopted in December 2015 during the COP21 climate conference stipulates that the increase in the global average temperature is to be kept well below 2°C above “pre-industrial levels” and that efforts are pursued to limit the temperature increase to 1.5°C above “pre-industrial levels.”

Closer inspection of the treaty text, however, reveals that the term “pre-industrial levels” is nowhere defined in this epochal UN-document, that has meanwhile been ratified by 170 Parties.

The report says: ‘On Earth, this relationship between distant events in a planet’s climate system is known as teleconnection.’ The surprise was to find evidence of it on both of the solar system’s two biggest planets.

Immense northern storms on Saturn can disturb atmospheric patterns at the planet’s equator, finds the international Cassini mission in a study led by Dr Leigh Fletcher from the University of Leicester.

This effect is also seen in Earth’s atmosphere, suggesting the two planets are more alike than previously thought, reports Phys.org.

Despite their considerable differences, the atmospheres of Earth, Jupiter, and Saturn all display a remarkably similar phenomenon in their equatorial regions: vertical, cyclical, downwards-moving patterns of alternating temperatures and wind systems that repeat over a period of multiple years.

These patterns—known as the Quasi-Periodic Oscillation (QPO) on Saturn and the Quasi-Quadrennial Oscillation (QQO) on Jupiter, due to their similarities to Earth’s so-called Quasi-Biennial Oscillation (QBO)—appear to be a defining characteristic of the middle layers of a planetary atmosphere.

‘Official’ climate science response: claim satellite data is not reliable, and play shoot-the-messenger. Predictable, as the results obviously don’t fit theories of man-made warming.
H/T The GWPF

Global warming has not accelerated temperature rise in the bulk atmosphere in more than two decades, according to a new study funded by the Department of Energy.

University of Alabama-Huntsville climate scientists John Christy and Richard McNider found that by removing the climate effects of volcanic eruptions early on in the satellite temperature record showed virtually no change in the rate of warming since the early 1990s.

“We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere’s sensitivity to CO2 much too high,” Christy said in a statement. “This recent paper bolsters that conclusion.”

‘Reports of the death of the global warming pause have been greatly exaggerated’, says David Whitehouse at The GWPF. If temperatures really were climbing would anyone bother with this sort of ‘science’?

A new paper in Nature Climate Change concludes that the so-called pause in global surface temperatures never happened. The paper has been mentioned in a few media outlets.

It claims that new data from the Arctic makes the pause go away – and so it seems until you look at the paper in a little more detail than news headlines suggest.

I got back from Rome last night following the highly successful World Climate Conference. Quite a number of CO2 sceptics gave presentations, which were politely received and discussed by all present. We even made a few converts. Here’s a short interview I made with Ned Nikolov and Karl Zeller where they give their impressions and some insight into their paradigm shifting discovery of the temperature-pressure relationship which holds good across the entire solar system.

Ned and Karl’s two papers are here:

New Insights on the Physical Nature of the Atmospheric Greenhouse
Effect Deduced from an Empirical Planetary Temperature Model

On the average temperature of airless spherical bodies and the magnitude of Earth’s atmospheric thermal effect

They show that the uplift in temperature on Earth’s surface due to the presence of the atmosphere is not 33K as the current greenhouse theory states but 90K, and is due to atmospheric pressure at the surface, not the back radiation from ‘greenhouse gases’.

We’ve been following Ned and Karl’s work since 2010 here at the Talkshop. They are finally getting heard in a wider forum.

Finding a measure of climate that can be successfully used to stir up public anxiety and fear is getting tougher for climate alarmists, as rowing back on earlier claims and scenarios – or at least postponing the supposed days of reckoning – becomes the order of the day.

Tony Abbott may have annoyed the climate change mob with his speech in London, but a far more serious problem for that industry is an admission that global temperatures have not been following climate models, says Climate Change Dispatch.

Besides the two papers making that admission, including one in Nature Geoscience, that massive industry also faces the problem of a possible La Niña this year, which will pull global temperatures down.

Selling disaster stories about rising temperatures, the main way the industry justifies itself, is harder if temperatures are falling rather than rising.

Enough is enough, at least for some Australians who are seeing through the alarmist propaganda smokescreen pushed by many of their recent leaders as an excuse to spend fortunes in the vain pursuit of unrealistic climate targets.

Finally the green madness that’s threatening our ability to turn on the lights and air conditioners is being exposed as a con, writes Julian Tomlinson (via The GWPF).

Global temperatures have risen nowhere near the rate at which even the most conservative models predicted, and finally a group of warmist scientists have admitted same in the Nature Geoscience journal last month.

Bear in mind the current mess Australia finds itself in with regards to power generation and business-killing high prices is a result of blindly following these flawed models.

Earth and climate – an ongoing controversy

A new study by Nicola Scafetta and colleagues is featured at The Global Warming Policy Forum (GWPF).

ABSTRACT The period from 2000 to 2016 shows a modest warming trend that the advocates of the anthropogenic global warming theory have labeled as the “pause” or “hiatus.” These labels were chosen to indicate that the observed temperature standstill period results from an unforced internal fluctuation of the climate (e.g. by heat uptake of the deep ocean) that the computer climate models are claimed to occasionally reproduce without contradicting the anthropogenic global warming theory (AGWT) paradigm.

In part 1 of this work, it was shown that the statistical analysis rejects such labels with a 95% confidence because the standstill period has lasted more than the 15 year period limit provided by the AGWT advocates themselves. Anyhow, the strong warming peak observed in 2015-2016, the “hottest year on record,” gave the impression that the temperature standstill stopped in 2014. Herein, the authors show that such a temperature peak is unrelated to anthropogenic forcing: it simply emerged from the natural fast fluctuations of the climate associated to the El Niño–Southern Oscillation (ENSO) phenomenon.

Earth and climate – an ongoing controversy


They could perhaps have taken more notice of this paper by Spencer and Braswell six years ago, which found that Earth’s atmosphere is more efficient at releasing energy to space than models used to forecast climate change have been programmed to “believe.”
H/T The GWPF.

As egg-on-face moments go, it was a double-yolker, writes Nigel Hawkes in The Sunday Times [restricted access].

Last week a group of climate scientists published a paper that admitted the estimates of global warming used for years to torture the world’s conscience and justify massive spending on non-carbon energy sources were, er, wrong. 

The admission was overdue acknowledgment of something that has been obvious for years.

cagwComputer modelling used a decade ago to predict how quickly global average temperatures would rise may have forecast too much warming, a study has found.

Myles Allen, professor of geosystem science at the University of Oxford and one of the study’s authors told The Times: “We haven’t seen that rapid acceleration in warming after 2000 that we see in the models. We haven’t seen that in the observations.”
