Deep Bore Into Antarctica Finds Freezing Ice, Not Melting as Expected

by Douglas Fox, February 16, 2018 in NationalGeographic


Scientists have peered into one of the least-explored swaths of ocean on Earth, a vast region located off the coast of West Antarctica. It is locked beneath a crust of ice larger than Spain and more than 1,000 feet thick, making its waters perpetually dark—and extremely difficult for humans to access. Now, a team of researchers has bored a hole through the ice and sampled the ocean beneath it. Their work could shed light on a poorly understood, but ominous episode in Antarctica’s recent past… (…)

The Source Of The Heat

by W. Eschenbach, March 9, 2018 in WUWT


I’m sure you can see the problem with Dr. Judith’s question—temperatures can rise without ANY new sources of heat or ANY change in existing sources of heat.

For example, regarding the climate system, every year there is more and more oil that goes into the ocean. This oil floats on the surface in a monomolecular layer, and it reduces both conduction and evaporation. As a result, the oceans end up slightly warmer than they would be without the oil … where is Dr. Judith’s mysterious “source of heat” supposedly driving that change?

Here’s another example … (…)

“Climate-Pope” Schellnhuber Stepping Down …Growing Impression He Had Become “More Activist Than Physicist”

by P. Gosselin, March 9, 2018 in NoTricksZone


Schellnhuber is often worshipped by the fringe-element climate alarmists as a sort of Climate Pope, whose every uttered word is to be regarded as infallible.  Now he may be paying the price for his entrenched, radical positions on climate change.

We now seriously need a Schellnhuber timeout. […] We do hope the new PIK leadership will correct the extreme direction the institute is currently on and rapidly puts an end to the flow of climate-alarmist press releases.“

Crucial Climate Verdict, Naked Conflict-of-Interest

by D. Laframboise, January 29, 2018 in BigPicturesNews…


BIG PICTURE: In November 1995, the Intergovernmental Panel on Climate Change (IPCC) declared for the first time that humans were changing the climate. Its verdict turned on a single piece of then-unpublished research. Four months after the fact, the research was submitted to a prominent journal. Three months later it was published.

The world then learned that 25% of the IPCC personnel tasked with making its most crucial determination were involved with this research. In a naked a conflict-of-interest, these nine people, led by IPCC chapter head Ben Santer, had evaluated the persuasiveness of their own fledgling scientific work – and had judged it sound enough to change history.

Scientists Admit We Need Better Thermometers To Measure Climate Change

by M. Bastach, March 3, 2018 in DailyCaller


A group of prominent scientists are calling for a global network of advanced weather stations that don’t need to go through controversial data adjustments, and it’s vindication for global warming skeptics.

Seventeen climate scientists co-authored a research article published in the International Journal of Climatology calling for a global climate station network modeled after the United States Climate Reference Network (USCRN) to use as a baseline for data quality.

Le réchauffement climatique actuel : une évolution thermique naturelle au forçage oublié

by Brigitte Lanoë in MythesManciesMathématiques


Le forçage climatique principal est l’énergie apportée par le soleil sous la forme primaire de rayonnement visible et UV, l’insolation. Son lieu de stockage principal est l’océan, le thermostat de notre planète. Le gaz le plus abondant à côté de l’azote et de l’oxygène est la vapeur d’eau dont la teneur est éminemment variable dans l’atmosphère (de 0,2 % à 7,6 %). John Tyndall conclut dès 1861 que l’effet de serre est dû essentiellement à cette dernière. Il faut rappeler que le potentiel diffusif thermique induit par la vapeur d’eau est 8 fois supérieur à celui du CO2 à concentration égale (0,04 %). L’immense majorité des articles traitant du changement climatique ne prennent en compte que l’hémisphère nord et l’Antarctique. Or, dans l’hémisphère sud (…)

Rebuttals to Ten Typical False Claims by Climate Alarmists

by Alan Carlin, February 20, 2018 in CarlinEconomicsandScience


Climate alarmists are constantly trying to justify their misguided goal of decreasing emissions of carbon dioxide (CO2), one of the basic molecules that makes possible life on Earth, by making various claims as to the alleged adverse effects of increasing emissions of CO2. To date these claims have either been shown to be false or better explained by natural causes.

Recognizing The Obvious: World CO2 Emissions Will Continue To Increase

by Francis Menton, February 25, 2018 in ManhattanContrarian


Every day you read about the crisis of climate change and fossil fuel usage and CO2 emissions, and commitments from politicians around the world to “act” to “save the planet.”  Surely then, CO2 emissions are in steep decline and headed for zero.

The truth is of course the opposite.  In the developed world, rapidly increasing use of “renewables” like intermittent wind and solar energy only serves to drive electricity prices through the roof, while having only the most marginal effect on reducing emissions.

Remember when we were told “Penguins Don’t Migrate, they’re dying!” ? – never mind

by A. Watts, March 2, 2018 in WUWT


WUWT readers may remember this story from last year, where Chris Turney, leader of the ill fated “ship of fools” Spirit of Mawson expedition that go stuck in Antarctic sea ice said: “Penguins Don’t Migrate, they’re dying!” and of course blamed the dreaded “climate change” as the reason. Of course three days later, Discover Magazine ran an article that suggested Turney was full of Penguin Poop.

Well, seems there’s a surplus of Penguins now, in a place nobody thought to look, there’s an extra 1.5 million Penguins. From Woods Hole Oceanographic Institute.

Continental United States Hurricane Landfall Frequency and Associated Damage: Observations and Future Risks

by Ph. Klotzbach et al., February 2018 in Amer.Met.Society


.pdf (56 pages)

Continental United States (CONUS) hurricane-related inflation-adjusted damage has increased significantly since 1900. However, since 1900 neither observed CONUS landfalling  hurricane frequency nor intensity show significant trends, including the devastating 2017 season.

Two large-scale climate modes that have been noted in prior research to significantly impact CONUS landfalling hurricane activity are El Niño-Southern Oscillation on interannual timescales and the Atlantic Multi-decadal Oscillation on multi-decadal timescales. La Niña seasons tend to be characterized by more CONUS hurricane landfalls than do El Niño seasons, and positive Atlantic Multi-decadal Oscillation phases tend to have more CONUS hurricane landfalls than do negative phases.

A new but unbelievable climate proxy – plant leaf wax

by University of Birmingham, March 2, 2018, in WUWT


As the Earth’s surface and atmosphere warm, the amount of moisture – water vapour – in the atmosphere will increase. Understanding the size of this increase is important for predicting future climates as water vapour is a significant greenhouse gas. Atmospheric moisture content also influences the patterns and intensity of rainfall events.

The relationship between temperature and moisture content can be explored by the study of intervals in Earth’s history when climates where significantly warmer than those seen in modern times, which necessitates a method for estimating ancient atmospheric moisture content.

A 1D Model of Global Temperature Changes, 1880-2017: Low Climate Sensitivity (and More)

by Dr Roy Spencer, February 22, 2018 in GlobalWarming


UPDATE(2/23/18): The previous version of this post had improper latitude bounds for the HadCRUT4 Tsfc data. I’ve rerun the results… the conclusions remain the same. I have also added proof that ENSO is accompanied by its own radiative forcing, a controversial claim, which allows it to cause multi-decadal climate change. In simple terms, this is clear evidence the climate system can cause its own, natural, internally-generated climate changes. This is partly what has caused recent warming, and the climate modelling community has assumed it was all human-caused.
