Volcanic Heat Found Under Antarctica’s Fastest-Melting Glacier

by M.  Bastach, June 28, 2018 in ClimateChangeDispatch


A group of scientists at the University of Rhode Island stumbled on something unexpected when analyzing data brought back from a 2014 expedition to western Antarctica.

Scientists found an abundance of the noble gas Helium-3, indicating there is a volcanic heat source beneath the Pine Island glacier — the fastest melting glacier in the South Pole. The findings were published in a study in the journal Nature Communications.

“When you find helium-3, it’s like a fingerprint for volcanism. We found that it is relatively abundant in the seawater at the Pine Island shelf,” chemical oceanographer Brice Loose, the study’s lead author, said in a statement.

What Scientific ‘Consensus’? 254 New 2018 Papers Support A Skeptical Position On Climate Alarmism By Kenneth Richard on 28. June 2018

by K. Richard, June 28, 2018 in NoTricksZone


In just the first 6 months of 2018,  254 scientific papers have been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources.

Hallucinations in High Places (More on the 1988 Hansen Climate Hearing)

by Donna Laframboise, June 27, 2018 in BigPictureNews


SPOTLIGHT: The event in which Jim Hansen put climate change on the media map has triggered hallucinations in high places.

BIG PICTURE: I’ve previously discussed how Timothy Wirth, who chaired an historic US senate committee hearing in 1988, has given two accounts of what happened prior to its commencement.

During a 2007 television interview, he jovially described taking measures to circumvent the air conditioning in the meeting room. Global warming was being discussed, and those in attendance were sweltering. After being challenged by a Washington Post fact checker in 2015, however, Wirth caved. In a written statement, he said the pre-hearing measures didn’t happen. Those were just rumours he’d heard. (…)

Worse than they thought: Antarctica actually colder than scientists once believed

by Anthony Watts, June 25, 2018 in AGU/WUWT


From the AGU and the “but, but, the continent is melting!” department.

COLDEST PLACE ON EARTH IS COLDER THAN SCIENTISTS THOUGHT

WASHINGTON — Tiny valleys near the top of Antarctica’s ice sheet reach temperatures of nearly minus 100 degrees Celsius (minus 148 degrees Fahrenheit) in the winter, a new study finds. The results could change scientists’ understanding of just how low temperatures can get at Earth’s surface, according to the researchers.

Scientists announced in 2013 they had found the lowest temperatures on Earth’s surface: Sensors on several Earth-observing satellites measured temperatures of minus 93 degrees Celsius (minus 135 degrees Fahrenheit) in several spots on the East Antarctic Plateau, a high snowy plateau in central Antarctica that encompasses the South Pole. But the researchers revised that initial study with new data and found the temperatures actually reach minus 98 degrees Celsius (minus 144 degrees Fahrenheit) during the southern polar night, mostly during July and August.

What Really Happened 30 Years Ago?

by Donna Laframboise, 25 June 2018 in BigPictureNews


SPOTLIGHT: Competing accounts of an historic climate hearing.

BIG PICTURE: June 23rd, 1988 is considered the day the climate crusade hit the jackpot. Thirty years ago, a sea of television cameras recorded NASA’s James Hansen testifying before a US Senate committee.

The “greenhouse effect has been detected, and it is changing our climate now,” he said. There was “99 percent confidence” that human-caused global warming was underway.

The person chairing the committee was Democratic Senator Timothy Wirth. Nine years later, when interviewed by PBS’s Frontline, he cheerfully revealed that the date of the hearing had been specially chosen.

History of the global warming scare 1980-2010

by Prof. Cha-am Jamal Munshi, June 16, 2018 in theRefFrame


LM: I found this itemized list rather impressive even though it’s in no way complete. Whether we live in Thailand or Europe, we have been exposed to a very large amount of fearmongering and failed predictions. The explosion of these news in 2005-2010 is easily seen in the lists below. After 2010, the growth arguably stopped or reversed so this contribution may be considered the work by a historian. There’s a clean mobile version of this page.

Can Universities Lawfully Bully Academics into Silence?

by Jennifer Marohasy, June 19, 2018


Dr Peter Ridd has taken James Cook University to court protesting his sacking for what he says is, primarily, speaking-out about the lack of quality assurance in Great Barrier Reef science.

Dr Ridd spoke out initially about there being no quality assurance of Great Barrier Reef science – science that is arguably misused to secure billions of dollars of tax-payer funding. When the University tried to stop Dr Ridd doing this, Dr Ridd spoke out against University management – making all the documentation public including on his new website.

Where’s the warming!

The Arctic and North Atlantic have suddenly turned surprisingly cold. First, according to Weatherbell meteorologist Joe Bastardi, the northern Atlantic has turned cold; so cold in fact that Bastardi called it “impressive”: …

All the Atlantic cold could have a big (positive) impact on the upcoming hurricane season, says hurricane expert Philip Klotzbach. One week ago Klotzbach tweeted …

Sea level rise: isostatic adjustment

by Judith Curry, June 23, 2018 in ClimateEtc.


Assuming that the uncertainty in GIA adjustments are ‘in the noise’ of global sea level rise may not be entirely justified.  The adjustments to the satellite data that emerged in the discussion between Morner and Nerem do not inspire confidence in the estimate of sea level rise from satellite data, and the low level of stated uncertainty strains credulity.

The Failed Predictions Of James Hansen

by P. Homewood, June 22, 2018 in NotaLotofPeopleKnowThat


“Thirty years of data have been collected since Mr. Hansen outlined his scenarios—enough to determine which was closest to reality. And the winner is Scenario C. Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16. Assessed by Mr. Hansen’s model, surface temperatures are behaving as if we had capped 18 years ago the carbon-dioxide emissions responsible for the enhanced greenhouse effect. But we didn’t. And it isn’t just Mr. Hansen who got it wrong. Models devised by the United Nations Intergovernmental Panel on Climate Change have, on average, predicted about twice as much warming as has been observed since global satellite temperature monitoring began 40 years ago…”

“Several more of Mr. Hansen’s predictions can now be judged by history. Have hurricanes gotten stronger, as Mr. Hansen predicted in a 2016 study? No. Satellite data from 1970 onward shows no evidence of this in relation to global surface temperature. Have storms caused increasing amounts of damage in the U.S.? Data from the National Oceanic and Atmospheric Administration show no such increase in damage, measured as a percentage of gross domestic product. How about stronger tornadoes? The opposite may be true, as NOAA data offers some evidence of a decline. The list of what didn’t happen is long and tedious.”

German National Daily ‘Die Welt’ On CO2 Reduction: “Why Has It Been 5 To Midnight 30 Years Long?”

by P. Gosselin, June 20, 2018 in NoTricksZone


Sustainable alarm, unending hoax. Commentary at Germany’s ‘Die Welt’: Why has the climate-last-chance alarm been blaring 30 years long now? And why has the planet today “suddenly” just been given yet another 20 years by experts?

Remember how in 2007 Al Gore warned we had only 10 more years to act?

Well, those 10 years have long since expired, and that deadline came and went without the planet changing much. Embarrassed, global warming alarmists quietly pushed the doomsday back once again. And this time it was for real.

This game has been going on for years now.

Today, business journalist Daniel Wetzel here in a commentary at German national daily Die Welt finally is wondering why it’s been “5 to midnight for 30 years now”!

Ross McKitrick: All those warming-climate predictions suddenly have a big, new problem

by Ross McKitrick, June 20, 2018 in FinancialPost


One of the most important numbers in the world goes by the catchy title of Equilibrium Climate Sensitivity, or ECS. It is a measure of how much the climate responds to greenhouse gases. More formally, it is defined as the increase, in degrees Celsius, of average temperatures around the world, after doubling the amount of carbon dioxide in the atmosphere and allowing the atmosphere and the oceans to adjust fully to the change. The reason it’s important is that it is the ultimate justification for governmental policies to fight climate change.

The United Nations Intergovernmental Panel on Climate Change (IPCC) says ECS is likely between 1.5 and 4.5 degrees Celsius, but it can’t be more precise than that. Which is too bad, because an enormous amount of public policy depends on its value. People who study the impacts of global warming have found that if ECS is low — say, less than two — then the impacts of global warming on the economy will be mostly small and, in many places, mildly beneficial.

No. The Miocene is not an example of the “last time it was as warm as it’s going to get later this century”… Argh!

by David Middleton, June 19, 2018 in WUWT


From ARS Technica, one of the most incoherent things I’ve ever read…

The shocking thing is that Howard Lee has a degree in geology.  The fact that he makes his living as an “Earth Science writer” and not as a geologist might just be relevant.

Can the Miocene tell our future?  I’ll let Bubba’s mom answer that question:

 

Paris Accord Humiliation: 23 Of 28 EU States Graded “Poor” Or “Very Poor” On Achieving Climate Targets!

by P. Gosselin, June 19, 2018 in NoTricksZone


Not a single EU state is meeting its climate targets, a new analysis by CAN Europe finds.

It’s been close to three years since countries worldwide signed the Paris Agreement, which obligates nations pledge to commit themselves to intending (or something like that) to reduce their greenhouse gas emissions in order to “safeguard the planet’s future”.

The language of the Agreement is in fact non-binding, and so one wouldn’t be surprised to learn that some signatories might not be living up to the agreement’s spirit.

NASA glaciologist Jay Zwally puts the hammer down: ‘Antarctica is gaining ice’

by Michael Bastach, June 15, 2018 in A. Watts WUWT


A new paper about to be in press, comes at the end of a flurry of papers and reports published this week that claims Antarctica was losing ice mass. Zwally says ice growth is anywhere from 50 gigatons to 200 gigatons a year. NASA glaciologist Jay Zwally says his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west.

Antarctic Ice Loss Tripled, from near zero to an extremely tiny number! (Nobody mention those volcanoes)

by JoNova, June 15, 2018


Quick — tax the magma

It’s another round of Antarctic Doom about next to nothing. In April Antarctica’s ice was melting five times faster than usual. Now it’s losing ice three times faster in the last five years than the 15 before that! What you won’t hear is how the Antarctic ice cap has 29 million cubic kilometers of ice and has been there for 30 million, mostly warmer, years. You also won’t hear how Antarctica was warmer in Roman Times, or that the  Antarctic Peninsula has cooled by almost 1 degree.

You also won’t hear a word about any volcanoes

The new paper has zero mentions of the word. But other scientists have published plenty of papers describing how the West Antarctic zone is being warmed from below by 1200 degrees of magma. According to scientist Dustin Schroeder and co,  it is as if the Thwaites Glacier in West Antarctic is sitting on a “stovetop burner”.[1]  His words. Thwaites Glacier,, smack in the middle of the warming is being melted from below by geothermal heat. Then there is the large blob of superheated rock 60 miles below West Antarctica. The researchers use the phrase “like a blow-torch”….  Capping it off, only last year 91 new volcanoes were discovered 2km underneath the West Antarctic Rift. That’s new, as in, we didn’t know they were there.

Follow the reasoning, either a trace gas 10 kilometers up is causing some spots of Antarctica to warm and other parts to cool, or hot magma at 1,200C is. What’s more likely?

HOW THE EARTH BECAME A HOTHOUSE BY H2O

by Wim Röst, June 15, 2018 in WUWT


Water, H2O, determines the ‘General Background Temperature’ for the Earth, resulting in Hothouse and Ice House Climate States. During geological periods the movement of continents changes the position of
continents, oceans and seas. Because of the different configurations, a dominant warm or a dominant cold deep-water production configuration ‘sets’ average temperatures for the deep oceans. Changing vertical oceanic circulation changes surface temperatures, especially in the higher latitudes. During a Hot House State, higher temperatures in the high latitudes result in a high water-vapor concentration that prevents a rapid loss of thermal energy by the Earth.

These three processes, plate tectonics (continental drift), vertical oceanic circulation variability and variations in atmospheric water vapor concentration and distribution, caused previous Hot House and Warm House Climate States. A change in the working of those mechanisms resulted in a transition from the previous Hot House Climate State to the very cold ‘Ice House State’ that we live in now. That change was set in motion by the changing configuration of continents, oceans and seas.

NSF study: ‘…current carbon dioxide levels are not enough to destabilize the land-based ice on Antarctica’

by Anthony Watts, June 15, 2018 in WUWT


We covered this yesterday, but today the official press release came out, so worth covering again. Via Eurekalert


Land-based portion of massive East Antarctic ice sheet retreated little during past eight million years

But increases in atmospheric carbon dioxide levels could affect stability and potential for sea level rise

NATIONAL SCIENCE FOUNDATION

Large parts of the massive East Antarctic Ice Sheet did not retreat significantly during a time when atmospheric carbon dioxide concentrations were similar to today’s levels, according to a team of researchers funded by the National Science Foundation (NSF). The finding could have significant implications for global sea level rise.

Large scale implementation of cool asphaltic and concrete photocatalytic pavements

Extensive monitoring strategy of in situ measurements in the area

Surface temperatures reduction up to 7.5 °C and 6.1 °C respectively in the summer period, while the peak drop was up to 11.5 °C

The maximum air temperature reduction could reach 1.5 °C.

Ageing phenomena may reduce substantially and up to 50% the mitigation potential of cool asphaltic materials.

Government scientist urges caution linking hurricanes to warming

by  CFACT, June 6, 2018


There’s periods where it’s busy and quiet and busy and quiet, but no trend,” said Landsea, “There’s no statistical change over a 130-year period. Since 1970, the number of hurricanes globally is flat. I haven’t seen anything that suggests that the hurricane intensity is going to change dramatically. It looks like a pretty tiny change to how strong hurricanes will be. It’s not zero, but it’s in the noise level. It’s very small.”
