They say “By shading and cooling the Earth’s surface, cloud cover plays a direct role in rates of global climate change”, but that’s only half the story. Cloud cover at night, i.e. the other 50% of the year, has the opposite effect and slows the rate of heat loss.

Everyday our atmosphere has to find a way to clean itself of the air, sea and soil pollution we throw at it, says Phys.org.

So, in order to study how this cleaning process works, the University of Melbourne’s Dr. Robyn Schofield is sailing through the pristine environment of the Southern Ocean to our most untouched continent, Antarctica—an environment with the least amount of pollution on the planet.

Basing government energy policy on inaccurate, failing models is getting ever harder to justify. Predictions of severe climate problems have not materialised.

The US government has funded more than 100 efforts to model our climate for the better part of three decades; none have come close to actual results, says ClimateChangeDispatch.

They are exercising precisely what prominent writer H.L. Mencken described as “the whole point of practical politics is to keep the populace alarmed and hence clamorous to be led to safety by menacing it with an endless series of hobgoblins, all of them imaginary”.

Playing around with CO2 levels doesn’t work, either in climate models or real life.

CO2 is Life

Run the above experiment 1 billion times and you will get 1 billion identical outcomes. Now, look at the “settled science” of climate science. They have multiple models, none of them agree, and worse, they don’t accurately reflect reality. The only thing “settled” about climate science is that the climate experts don’t have a clue as to how to model the climate.

Don’t take it from me, listen to the true experts.

Many new scientific papers affirm climate model results conflict with one another, diverge from observations, and aren’t fully rooted in established physics. (Source)

Topographic map of Greenland


Such predictions are usually wrong anyway, the real question being the degree of ‘wrong-ness’ compared to the actual data. The expected (by climate models) linear progression of global temperatures has fizzled out – inasmuch as it ever existed – since the ‘pause’, apart from a recent El Niño blip. Solar cycle activity is also declining compared to other recent cycles..

Current climate change predictions in the UK and parts of Europe may be inaccurate, a study conducted by researchers from the University of Lincoln, UK, and the University of Liège, Belgium, suggests.

Existing computer model simulations have failed to properly include air pressure changes that have occured in the Greenland region throughout the past 30 years, says The GWPF.

…and don’t get the answers their models led them to expect. Could the close proximity to their star of most exoplanets so far observed be a factor?

Sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes, a finding by researchers at NYU Abu Dhabi that challenges current science on how stars rotate, reports Phys.org.

Until now, little was known about the precise rotational patterns of Sun-like stars, only that the equator spins faster than at higher latitudes, similar to the Sun.

Not the actual simulations, but the already fading credibility thereof. What scientific reason is there to rely on their results?

Ross McKitrick and John Christy have an important new paper out in Earth and Space Science, writes Andrew Montford for The GWPF.

This is the latest fusillade in the long battle over whether the climate simulations that lie behind demands for decarbonisation and other political action actually amount to nothing but a hill of beans (as they say on the other side of the pond).

Could a ‘rogue’ star passing nearby have disturbed outer parts of the early solar system? Beyond Neptune things become somewhat different.

The outer reaches of our solar system harbor a number of mysterious features. Astrobites reports on whether a single stellar fly-by could help explain them all.

A star is born from the gravitational collapse of a cloud of gas and dust. Yet not all of the material ends up in the star, and instead forms a flat protoplanetary disk that surrounds the new star. Over time, the materials in this disk coalesce to form planets, moons, asteroids, and most other objects you might expect to find near a typical star.

Since protoplanetary disks are flat, the expectation is that all of the planets and objects orbiting a star that formed out of a protoplanetary disk should orbit on a single plane. So when we find stars with planets that orbit at multiple different inclinations, this raises questions.

CO2islife concludes: ‘If you have to “adjust” the data to make your model work, your model is wrong, it is that simple.’

CO2 is Life

In any real science great care is given to “controlling” for exogenous factors. The whole purpose of the scientific method is to relate the impact of an independent variable upon a dependent variable, removed from any other factors. Y = mX + b + e, is the formula of a linear regression, and e is the error of the model. In order to minimize the “e,” one must control for as many outside factors that may impact the dependent variable as possible. In climate science, efforts to control for exogenous factors is completely absent. In fact, by choosing the highly flawed and “adjusted” ground measurements they are effectively maximizing the impact of exogenous factors on their data set and minimizing the usefullness of their preferred data set to identify and isolate the impact of CO2 on atmospheric temperatures.

In climate science, the main model being promoted is Temperature is a…

Since climate scares were first sponsored by governments, neither the theory of man-made causality nor the evidence for it have improved. Models have failed to predict what actually happened. Time’s almost up for alarmists.

Fool Me Once Shame on You,
Fool Me Twice, Shame on Me.

It was just 30 years ago this week that James Hansen, the former NASA scientist who testified before the Senate Energy and Natural Resources Committee during a prolonged heat wave, which” he described as a climate event of cosmic significance.” Just to be sure he arranged for the meeting room to be warmer than usual. He expressed to the senators “his high degree of confidence” in “cause-and-effect relationship between the greenhouse effect and observed warming.”

There was an accompanying paper in the Journal of Geophysical Research, and it ignited a world wide panic that continues today about the energy structure of the entire planet. So 30 years on we can pause and take a look at just how well his predictions have turned out, and check on how we are doing.

Mr. Hansen’s testimony described three possible…

The climate propaganda/scare machine never stops, but somewhere out there is another thing called reality, which may contradict it.

Models Of Stranded Fossil Fuel Assets Cannot Be Trusted

The GWPF is today publishing a brief comment on the recent and much publicised paper in Nature Climate Change by J.-F. Mercure et al.

Dr Mercure and his colleagues offer modelled outputs to suggest that fossil fuel demand will fall sharply on the basis of current policies, and with additional policies arising from the Paris Agreement commitments they predict that the value of fossil fuel assets will collapse by 2035.

A lay person’s view of the global warming furore. When we hear ‘unprecedented’ it usually turns out to mean ‘since about 1979’, which obviously leaves out most of Earth’s history.

American Elephants

You have heard the wailing and screaming about President Trump’s exit from the Paris Climate Accords, but do you understand that the agreement, never ratified by the U.S. government (NOT a treaty) accomplished nothing at all to modify or change the climate. The climate of the earth has been changing mildly for millions of years, and there is no unprecedented Global-Scale modern warming. The “Accords” were designed to transfer large amounts of wealth from the rich nations to the poor nations, ostensibly to allow them to save themselves from that non-existent unprecedented warming.

There are two kinds of climate science that we are dealing with. One is based on satellite measurements and thermometer readings and recorded history. The other is based on computer programs, based, I believe on computer programs that were designed to forecast what the financial markets were going to do. They took what they knew about the…

The headline from the source should perhaps mention that those ‘variations’ can include ‘no global warming trend’, or hiatus, as explained below.

New research has shown that natural variations in global mean temperature are always forced by changes in heat release and heat uptake by the oceans, in particular the heat release associated with evaporation, reports Phys.org.

Analysing data from six climate models that simulated future climate change scenarios for the last International Panel for Climate Change (IPCC) Report, which appeared in 2014, University of Southampton Professor Sybren Drijfhout has shown that in all cases variations in global mean temperature were correlated with variations in heat release by sensible and latent heat.

In their latest report the authors point out: ‘it is never mathematically proper to attempt to validate any theory embedded in a model using the model itself.’

As discussed last week, several reports have shown in the last year or two that carbon dioxide (CO2) does not significantly affect global temperatures, contrary to endless repetitions to the contrary by climate alarmists and the mainstream press.

Today some of the same authors of the reports discussed last week have released a new report that among other things makes a similar point using a different data set, making a total of 15 such data sets between the earlier reports and this new report.

The edge of the Thwaites glacier [credit: NASA photograph by Jim Yungel]


This BBC report seems unaware that a study in 2014 found that parts of the Thwaites Glacier are subject to melting due to subglacial volcanoes and other geothermal “hotspots”. The existence of this group of volcanoes has long been known.

British and American scientists will assess the stability of one of Antarctica’s biggest ice streams, reports BBC News.

It is going to be one of the biggest projects ever undertaken in Antarctica.

UK and US scientists will lead a five-year effort to examine the stability of the mighty Thwaites Glacier.

Two professors question the validity of current climate modelling, pointing to a number of apparent difficulties.

New understanding of ultra-long timescales provides a new take on climate, says The GWPF.
– – –
A newly published paper in the journal Physica A suggests that there is an undiscovered universe all around us that we are too short-lived to perceive.

Authors Prof. Christopher Essex (Applied Mathematics, University of Western Ontario) and Prof. Anastasios Tsonis (Mathematical Sciences, University of Wisconsin-Milwaukee) explain that even without external influences (e.g. man-made carbon dioxide) the weather patterns change over very long timescales, locally and globally.

If some elderly person claims to recall summers, say, that were different when that person was a child, that may not be faulty memory. Just because summers seemed warmer or colder; spring or winter seemed sooner; more or less snow was recalled, it doesn’t follow that the climate system has changed in any meaningful way.

Prof. Essex explains, “Unlike the stable virtual ‘climates’ seen in computer simulations, corresponding real-world conditions aren’t stable at all. There are perpetual, natural, internal changes in play that take longer than human lifetimes to play out.”

ClimategateFictionI ran across this interesting exchange recently. In it, James Annan, one of the IPCC authors who got Pattern Recognition in Physics shut down after we published our findings on the solar-planetary theory in it because he thought it was wrong, doesn’t seem as bothered to deal with errors by his fellow oceanographer Syd Levitus. Not even when it’s a whopper that has been costing the taxpayer billions due to the climate! panic! James and his colleagues have promoted for years.

James Annan did eventually write a short letter to the journal, but it went unpublished. The Levitus papers were never corrected, though later IPCC reports show a figure for 1955-96 closer to 13×10^22J than the 18×10^22J Levitus et al reported. The increase was actually caused by the reduction in cloud cover letting more sunshine through, as measured by the ISCCP. The latest graphs have also ‘disappeared’ the fall in OHC between 2003-9 measured by ARGO buoys and replaced it with a rise.

Antarctic sea ice is still expanding [image credit: BBC]


The conclusion offered here is that ‘something must be fundamentally wrong with the climate models, for their predictions to be so far off from the observed sea ice trends’. No wonder climate alarmists focus on the Arctic.

Over the past several years, many researchers have examined the spatial extent of sea ice around Antarctica, says CO2 Science, consistently reporting an increasing trend (see, for example, our reviews on the previously published works of Yuan and Martinson, 2000, Watkins and Simmonds, 2000, Hanna, 2001, Zwally et al., 2002, Vyas et al., 2003, Cavalieri et al., 2003, Liu et al., 2004, Parkinson, 2004, Comiso and Nishio, 2008, Cavalieri and Parkinson, 2008, Turner et al., 2009, Pezza et al., 2012, Reid et al., 2013, Reid et al., 2015, Simmonds, 2015, He et al., 2016 and Comiso et al., 2017).

The latest study to confirm this ongoing expanse comes from the South American research team of De Santis et al. (2017).
