MSM: Eleven Minute Friendly Interview with Climate Skeptic Ian Plimer

by Eric Worrall, April 16, 2018 in WUWT


Sky News, one of Australia’s most popular news services, just gave climate skeptic and geologist Ian Plimer an honest opportunity to explain what is wrong with Australia’s climate obsessed energy policies.

Geologist Ian Plimer told The Outsiders that Energy Minister Josh Frydenberg had caught himself ‘between a rock and a hard place’ when it comes to the government’s energy policies. Mr Plimer said it wasn’t possible for the energy market to provide cheap and reliable energy, but also reduce emissions.

Largest High-Arctic Lake Melting From Geothermal Heat, Not Global Warming

by James E. Kamis, April 16, 2018  in ClimateChangeDispatch


Recent changes to Lake Hazen, the world’s largest high-Arctic lake, are from increased heat flow from the area’s known geological features, and not from global warming as per the many alarmist media reports.

Evidence supporting this is abundant and reliable.

Northeast Canada’s Lake Hazen lies adjacent to the world-class Greenland/Iceland mantle plume.

Mountain erosion may add CO2 to the atmosphere

by Woods Hole Oceanographic Institution, April 12, 2018 in ScienceDaily


Scientists have long known that steep mountain ranges can draw carbon dioxide (CO2) out of the atmosphere — as erosion exposes new rock, it also starts a chemical reaction between minerals on hill slopes and CO2 in the air, ‘weathering’ the rock and using CO2 to produce carbonate minerals like calcite.

“Welcome to the Fabulous Anthropocene!”

by D. Middleton, April 12, 2018 in WUWT


Just to demonstrate that the American Association of Petroleum Geologists (AAPG) maintains an open mind about things, I thought I would share an recent AAPG Explorerarticle on the notion of establishing a formal geological epoch in honor of human beings…

(…)

I genuinely believe that these folks simply can’t grasp the concept of resolution.  This is a pervasive problem in the climate “science” community and will continued to feed claims of “unprecedented” changes in [fill in the blank] until we have about 1,000 years of high resolution instrumental data.

A Geological Perspective of the Greenland Ice Sheet

by D. Middleton, March 22, 2018 in WUWT


How Does the Recent Melting of the Greenland Ice Sheet Compare to the Early Holocene?

Short answer: Same as it ever was.  Vinther et al., 2009 reconstructed the elevations of four ice core sites over the Holocene.  There has been very little change in elevation of the two interior ice core sites (NGRIP and GRIP), while the two outboard sites (Camp Century and DYE3) have lost 546 and 342 m of ice respectively.

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.

Why did gas hydrates melt at the end of the last ice age?

by GEOMAR Inst., February 12, 2018 in WUWT


GEOMAR researchers find links between sedimentation and methane seeps on the seafloor off the coast of Norway

Large amounts of the greenhouse gas methane are locked up as solid gas hydrates in the continental slopes of ocean margins. Their stability depends on low temperatures and high pressure. However, other factors that influence gas hydrate stability are not as well understood. A German-Norwegian research team has found evidence off the coast of Norway that the amount of sediment deposited on the seafloor can play a crucial role. The study has been published today in the international journal Nature Communications.

Study: Early humans witnessed global cooling, warming, and massive fires from comet debris impacts

by U. of Kansas, February 2, 2018 in WUWT, A. Watts


 On a ho-hum day some 12,800 years ago, the Earth had emerged from another ice age. Things were warming up, and the glaciers had retreated.

Out of nowhere, the sky was lit with fireballs. This was followed by shock waves.

Fires rushed across the landscape, and dust clogged the sky, cutting off the sunlight. As the climate rapidly cooled, plants died, food sources were snuffed out, and the glaciers advanced again. Ocean currents shifted, setting the climate into a colder, almost “ice age” state that lasted an additional thousand years.

Finally, the climate began to warm again, and people again emerged into a world with fewer large animals and a human culture in North America that left behind completely different kinds of spear points.

Groundbreaking AGW-Undermining Study: Greenland’s Warming, Ice Loss Due To Geothermal Heat

by K. Richard, January 24, 2018 in NoTricksZone


A few years ago, 10 glaciologists publishing in the journal Nature Geoscience asserted that “large parts of the north-central Greenland ice sheet are melting from below” due to high geothermal heat flux forcing (Rogozhina et al., 2016).

In a new paper published in Scientific Reports, 4 more glaciologists (Rysgaardet al., 2018) report that “hot vents” (or hot springs) of geothermally-heated water underneath the Greenland ice sheet can explain localized rising temperatures and glacial melting.

Worse than we thought’ – climate models underestimate future polar warming

by  FLORIDA MUSEUM OF NATURAL HISTORY,  January 23, 2018, in WUWT, A. Watts


The researchers published their findings this week in the Proceedings of the National Academy of Sciences.

Scientists frequently look to the Eocene to understand how the Earth responds to higher levels of carbon dioxide. During the Eocene, the concentration of carbon dioxide in the atmosphere was more than 560 parts per million, at least twice preindustrial levels, and the epoch kicked off with a global average temperature more than 8 degrees Celsius – about 14 degrees Fahrenheit – warmer than today, gradually cooling over the next 22 million years. These characteristics make the Eocene a good period on which to test our understanding of the climate system, said Laura Cotton, study co-author and curator of micropaleontology at the Florida Museum of Natural History.

Earth’s Rotation Is Mysteriously Slowing Down: Experts Predict Uptick In 2018 Earthquakes

by Tevor Nace, November 20, 2017 in WhoaScience


Scientists have found strong evidence that 2018 will see a big uptick in the number of large earthquakes globally. Earth’s rotation, as with many things, is cyclical, slowing down by a few milliseconds per day then speeding up again.

You and I will never notice this very slight variation in the rotational speed of Earth. However, we will certainly notice the result, an increase in the number of severe earthquakes.

Geophysicists are able to measure the rotational speed of Earth extremely precisely, calculating slight variations on the order of milliseconds. Now, scientists believe a slowdown of the Earth’s rotation is the link to an observed cyclical increase in earthquakes.

Seafloor Volcano Pulses May Alter Climate

by Columbia University, February 5, 2015


Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles, ranging from two weeks to 100,000 years—and, that they erupt almost exclusively during the first six months of each year. The pulses—apparently tied to short- and long-term changes in earth’s orbit, and to sea levels–may help trigger natural climate swings. Scientists have already speculated that volcanic cycles on land emitting large amounts of carbon dioxide might influence climate; but up to now there was no evidence from submarine volcanoes. The findings suggest that models of earth’s natural climate dynamics, and by extension human-influenced climate change, may have to be adjusted

Further proof El Ninos are fueled by deep-sea geological heat flow

by Janes E Kamis, January, 27 in CliateChangeDispatch


The 2014-2017 El Nino “warm blob” was likely created, maintained, and partially recharged on two separate occasions by massive pulses of super-heated and chemically charged seawater from deep-sea geological features in the western North Pacific Ocean. This strongly supports the theory all El Ninos are naturally occurring and geological in origin. Climate change / global warming had nothing to do with generating, rewarming, intensifying, or increasing the frequency of the 2014-2017 El Nino or any previous El Nino.

If proven correct, this would revolutionize climatology and key aspects of many interrelated sciences such as oceanography, marine biology, glaciology, biogeochemistry, and most importantly meteorology. Information supporting a geological origin of El Ninos is diverse, reliable, and can be placed into five general categories as follows: (…)
