It’s been a bad winter all over – Snow in Japan 56 feet high!
by Anthony Watts, April 22, 2018 in WUWT
You think we had a bad winter here in the USA? Look at Japan where they have walls of snow 56 feet tall (almost the height of a 6-story building).
There’s an avalanche of tourists coming to the Tateyama to see the walls of snow.
It has been a rough winter full of snow all over the northern hemisphere, as this newest NOAA-20 satellite image shows

18 examples of the spectacularly wrong predictions made around the first “Earth Day” in 1970 Anthony Watts / 1 day ago April 21, 2018
by Anthony Watts, April 22, 2018 in WUWT
In the May 2000 issue of Reason Magazine, award-winning science correspondent Ronald Bailey wrote an excellent article titled “Earth Day, Then and Now” to provide some historical perspective on the 30th anniversary of Earth Day. In that article, Bailey noted that around the time of the first Earth Day in 1970, and in the years following, there was a “torrent of apocalyptic predictions” and many of those predictions were featured in his Reason article. Well, it’s now the 48th anniversary of Earth Day, and a good time to ask the question again that Bailey asked 18 years ago: How accurate were the predictions made around the time of the first Earth Day in 1970? The answer: “The prophets of doom were not simply wrong, but spectacularly wrong,” according to Bailey.
Here are 18 examples of the spectacularly wrong predictions made around 1970 when the “green holy day” (aka Earth Day) started

Dodo’s violent death revealed
by University of Warwick, April 21, 2018 in ScienceDaily
-
The famous Oxford Dodo died after being shot in the back of the head, according to new research. Using revolutionary forensic scanning technology and world-class expertise, researchers have discovered surprising evidence that the Oxford Dodo was shot in the neck and back of the head with a shotgun.
The significant and unexpected findings, made by Professor Paul Smith, director of the Museum of Natural History, and Professor Mark Williams from WMG at the University of Warwick, only became apparent when mysterious particles were found in the specimen during scans carried out to help analyse its anatomy.
CHALLENGING THE SCIENCE BASIS OF THE PARIS CLIMATE AGREEMENT
by Antero Ollila, April 16 in WUWT
COP21 does not define the scientific basis of the agreement for the warming effects of the anthropogenic emissions, but it refers to a scenario. This scenario has not been defined in the COP21, but it can be found. The scientific resource of United Nations as well as of the COP21 is IPCC. The exact specification of IPCC is (Summary for Policymakers. In: Climate Change 2014. Mitigation of Climate Change”): “Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 °C to 4.8 °C compared to pre-industrial levels (range based on median climate response; the range is 2.5 °C to 7.8 °C when including climate uncertainty)”. Even though IPCC refers to multiple scenarios in the text above, the surface temperature increase to the average value of 4.25 ⁰C means one scenario only.
10 new islands formed in the last 20 years
by Sidney Stevens, July 5, 2016 in mother.nature.network
Yes, islands are disappearing — most recently the five Solomon Islands lost to rising sea levels. But don’t despair just yet. For every island that goes the way of the dodo bird, the Earth is busy creating new islands.
Some erupt into being through volcanic activity. Others grow from ocean sandbars. Still others reveal themselves after glaciers retreat. A few are only temporary, while some materialize and erode on a regular basis. However they’re birthed and however long they last, island-building is part of the amazing mystery of our living, breathing planet.
Here are 10 of Mother Nature’s newest islands formed in the past two decades (and one still in the embryonic stage).

Unusual climate during Roman times plunged Eurasia into hunger and disease
by S. Writers, April 16, 2018 in TerraDaily
A recent study published in an esteemed academic journal indicates that volcanic eruptions in the mid 500s resulted in an unusually gloomy and cold period. A joint research project of the Chronology Laboratory of the Finnish Museum of Natural History and Natural Resources Institute Finland (Luke) suggests that the years 536 and 541-544 CE were very difficult for many people.

Easter Island’s “ecological suicide” – myths and realities
by Dennis Avery, April 7, 2018 in WUWT
In a recent New York Times column, Nicholas Kristof misleads us about the awful history of Easter Island (2,300 miles west of Chile), whose vegetation disappeared in the cold drought of the Little Ice Age. In doing so, he blinds modern society to the abrupt, icy climate challenge that lies in our own future.
Kristof repeats the archaeological myth that Easter Island’s natives committed “ecological suicide,” by cutting down all their palm trees. They supposedly used the logs as rollers to move their famous huge statues. Afterward, they could no longer build canoes to catch the fish that were their key protein source. Worse, he says, clearing the trees resulted in so much soil erosion that most of the population starved and/or killed each other in famine-driven desperation (…)
Journalism On Thin Ice…New York Times Misses Ton Of Recent, Positive Findings In Polar Bear Story
by P. Gosselin, April 14, 2018 in NoTricksZone
The New York Times recently published an article penned by Erica Goode on the controversial Harvey et al paper, where 14 scientists (sophomorically) attacked polar bear researcher Susan Crockford and climate science skeptics.
Sloppy biased journalism
So it is no surprise that Erica Goode at the New York Times sided up with the 14 scientists of the Harvey publication to attack the so-called climate “denialists” in her most recent article. Unfortunately Goode made the fatal journalistic error of failing to keep a healthy distance from the alarmist side and as a result was blinded from seeing the glaring mountain of scientific research showing polar bears are in fact doing fine.
Aussie PM: Coal to Hydrogen Plant Part of the Seamless Transition to Clean Energy
by Eric Worrall, April 13, 2018 in WUWT
h/t Geoff Sherrington – Coal is being rehabilitated as an essential component of the clean energy future.
Read more: http://www.abc.net.au/news/2018-04-12/coal-to-hydrogen-trial-for-latrobe-valley/9643570
Coal to hydrogen is not a new idea, the Water-gas shift reaction was discovered in 1780 by Italian Chemist Felice Fontana.
There are still some kinks to be worked out. The process to generate hydrogen from coal produces a monstrous amount of CO2 – far more CO2 per unit of useful energy than simply burning the coal would produce. But with hydrogen production, unlike hydrocarbon combustion, all the CO2 is produced in one place. This creates an opportunity for carbon sequestration, when technologies to sequester carbon on such an impressive scale are developed.
Thus It Begins

Scientists discover first super salty subglacial lakes in Canadian Arctic
by University of Alberta, April 11, 2018 in ScienceDaily
Super salty water beneath ice could serve as a terrestrial analogue for a habitat for life on other planets.
-
An analysis of radar data led scientists to an unexpected discovery of two lakes located beneath 550 to 750 meters of ice underneath the Devon Ice Cap, one of the largest ice caps in the Canadian Arctic. They are thought to be the first isolated hypersaline subglacial lakes in the world.
Estimated 40 Percent of Scientists Doubt Manmade Global Warming
by National Association of Scholars, January 03, 2011
PRINCETON, NJ (January 3, 2011)—S. Fred Singer said in an interview with the National Association of Scholars (NAS) that “the number of skeptical qualified scientists has been growing steadily; I would guess it is about 40% now.”
Singer, a leading scientific skeptic of anthropocentric global warming (AGW), is an atmospheric physicist, and founder of the Science and Environmental Policy Project (SEPP), an organization that began challenging the published findings of the UN’s Intergovernmental Panel on Climate Change (IPCC) in the 1990s. SEPP established the Leipzig Declaration, a statement of dissent from the 1997 Kyoto Protocol that has been signed by over one hundred scientists and meteorologists.

Sheikh Mohammed bin Khalifa al-Khalifa said it was not yet known how much of the oil could be extracted. The scale of the find, however, is about to make it a big player in the global market, significantly boosting its economy and raising its profile in the region, where it plays a smaller fiddle to its giant neighbour, Saudi Arabia.

Science is Not Truth
by Donna Laframboise, April 4, 2018 in ClimateChangeDispatch
SPOTLIGHT: As the influence of religion has waned, we’ve placed science on a pedestal – mistaking it for an oracle of truth.
BIG PICTURE: Richard Harris has written a startling book about the state of medical research. The preface to Rigor Mortis: How Sloppy Science Creates Worthless Cures, Crushes Hope, and Wastes Billions
includes a warning about scientific naivety:
Most of science is built on inference rather than direct observation…Science progresses by testing ideas indirectly, throwing out the ones that seem wrong…Gradually, scientists build stories that do a better job of approximating the truth.
Earth’s stable temperature past suggests other planets could also sustain life
by Anthony Watts, April 3, 2018 in WUWT
Theories about the early days of our planet’s history vary wildly. Some studies have painted the picture of a snowball Earth, when much of its surface was frozen. Other theories have included periods that would be inhospitably hot for most current lifeforms to survive.
New research from the University of Washington suggests a milder youth for our planet. An analysis of temperature through early Earth’s history, published the week of April 2 in the Proceedings of the National Academy of Sciences, supports more moderate average temperatures throughout the billions of years when life slowly emerged on Earth.

Climate-Related Deaths Down by 98.9%; Last Year All-Time Low
by Bjorn Lomborg, April 2, 2018 in ClimateChangeDispatsch
CCD Editor’s Note: In 1920, CO2 levels were 303 PPM or 0.03%. Last year they were 406 PPM or 0.04%. Despite our global population quadrupling, climate deaths have actually gone down as CO2 levels have gone up. Lomborg explains why with the now-standard, often-by-rote “this does not mean that there is no global warming” caveat.
Lake Chad Might Be Shrinking, But It Has Nothing To Do With Climate Change
by P. Homewood, April 1, 2018 in NotaLotofPeopleKnowThat
Lake Chad – a source of water to millions of people in West Africa – has shrunk by nine-tenths due to climate change, population growth and irrigation. But can a scheme dating back to the 1980s save it?
“It’s a ridiculous plan and it will never happen.” That’s the reaction many people have to the idea of trying to fill up Lake Chad and restore it to its former ocean-like glory by diverting water from the Congo river system 2,400km (1,500 miles) away.

To borrow from a philosophical thought experiment: If a volcano erupts in a remote part of the world and no one hears it, does it still make a sound?
Indeed, it does. And not only does the sound occur, but it also can tell scientists about the timing and duration of the eruption itself (…)
Terminal Pleistocene epoch human footprints from the Pacific coast of Canada

Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2–3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments (…)
LES EVENEMENTS CLIMATIQUES EXTREMES DU PASSE (18)
by Jo Moreau, 25 mars 2018 in Belgotopia
Suite n° 18. (anno 1800-1849)
“Le contenu de la mémoire est fonction de la vitesse de l’oubli”
Désormais, chaque inondation quelque peu catastrophique, chaque tornade, chaque anomalie météorologique est rattachée au réchauffement climatique qui parait-il nous menace, mais dont en plus l’homme serait responsable !
Pourtant, la consultation de chroniques ou récits anciens est révélatrice de précédents tout aussi apocalyptiques, et relativise la notion même de “changements climatiques”, ainsi que la définition d’un “climat stable” qui n’a jamais existé mais qu’on voudrait instaurer à tout prix.
