Tornadoes : Historical Records and Trends

by NOAA, August 2018


One of the main difficulties with tornado records is that a tornado, or evidence of a tornado must have been observed. Unlike rainfall or temperature, which may be measured by a fixed instrument, tornadoes are short-lived and very unpredictable. If a tornado occurs in a place with few or no people, it is not likely to be documented. Many significant tornadoes may not make it into the historical record since Tornado Alley was very sparsely populated during the 20th century.

Much early work on tornado climatology in the United States was done by John Park Finley in his book Tornadoes, published in 1887. While some of Finley’s safety guidelines have since been refuted as dangerous practices, the book remains a seminal work in tornado research. The University of Oklahoma created a PDF copy of the book and made it accessible at John Finley’s Tornadoes(link is external)

Hothouse Earth

by P. Homewood, August 7, 2018 in NotaLotofPeopleKnowThat


Climate change: ‘Hothouse Earth’ risks even if CO2 emissions slashed

It may sound like the title of a low budget sci-fi movie, but for planetary scientists, “Hothouse Earth” is a deadly serious concept.

Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.

Even if countries succeed in meeting their CO2 targets, we could still lurch on to this “irreversible pathway”.

Their study shows it could happen if global temperatures rise by 2C.

The utterly corrupt body of climate science has been getting ever more desperate to scare people about climate change and thereby submit to their radical anti capitalist agenda.

People are not falling for it, so we are now being subjected to ever more absurd announcements like this.

US Instrumental Records Indicate More Heat Waves Occurred In the 1930s Than Today

by K. Richard, August 6, 2018 in NoTricksZone


During the 1930s, when the atmospheric CO2 concentration was about 100 ppm lower than today (310 ppm vs. 410 ppm), United States heat waves were just as if not more common than recent decades.

Recently there has been much ado about heat waves and the hottest-ever-recorded-temperatures making their rounds in Northern Hemisphere summer.

Yet scientists have determined that heat waves are largely driven by natural variability, not anthropogenic CO2 emissions.

Climat : quand Nicolas Hulot joue à vous faire peur

by Samuele Furfari, 7 août 2018 in Contrepoints


Quelle aubaine pour les doctrinaires du développement durable ! Au moment de leur jour du dépassement il fait chaud, très chaud. Évidement ni l’écologisteHulot, ni France 2, ni France 24, ni la RTBF ni la ribambelle de médias impréparés ne pouvaient rater pareille occasion pour lier les deux évènements et nous culpabiliser pour introduire le contrôle de tous les détails de nos vies.

Ce premier août était donc le jour où, d’après Global Footprint Network (GFN), qui possède l’argent pour employer des dizaines de chercheurs souvent financés par les deniers publics, nous vivons désormais à crédit. À sa suite, toutes les ONG environnementales (ONGE) et nombre de politiciens se font les mégaphones de cette supercherie qui ne repose sur aucune base scientifique. Le jour du dépassement global (earth overshooting day) prétend être un indicateur dont l’objectif est de conscientiser et responsabiliser les pays développés à la notion d’empreinte écologique. Bien entendu, à part les Européens endoctrinés par les ONGE, cette théorie n’a guère d’écho dans le reste du monde.

 

‘This Is How Global Warming Will Play Out:’ 1931 Ocean Temp Record Broken By…0.2 Degrees?

by Mike Bastach, August 5, 2018 in WUWT


….

But while Scripps is trying to tie the record-high ocean reading to the broader wave of media coverage on global heat waves, there are a few caveats to note about what the scientists found.

First, these measurements are taken from a pier that’s near the shoreline, which would not necessarily make it representative of the entire Pacific Ocean, and therefore easily influenced by local weather events.

The “anomalously warm temperatures for the past week” that Scripps researchers observed at their pier somewhat mirror the temperature pattern in 1931, and indeed, the daily records broken in the past week have been very close to readings from 87 years ago.

There is an upward trend in temperature readings from Scripps’ pier, but the trend seems to also broadly coincide with the flipping of a natural ocean cycle, the Pacific Decadal Oscillation, to its warm phase. That flip occurred around 1976.

Ours mourant de faim : l’aveu (tardif) d’une journaliste

Il y a juste un an, l’image d’un ours décharné et titubant avait fait le tour du monde. Elle était supposée représenter la réalité du réchauffement de l’atmosphère. Pourtant cette hypothèse n’était pas plus probable qu’une autre, par exemple: ours vieux, malade, mourant de mort naturelle.

Arctic Sea Ice Volume Skyrockets…Atlantic Surface Cold Surprises Experts

by P. Gosselin, August 3, 2018 in NoTricksZone


Despite all the hysterical “heat wave” and drought reports being put out to the public by the media, the Northern Hemisphere as a whole is in fact not at all that much warmer than the mean since 2000.

According to Dr. Ryan Maue, northern hemisphere temperature anomaly was zero on July 30 and the northern hemisphere land surface anomaly was actually -0.20°C.

New Study Shows Some Corals Might Adapt to Climate Changes

by Anthony Watts, August 4, 2018 in WUWT


UM Rosenstiel School-led study exposes two threatened corals to future climate change conditions

MIAMI—New research shows that not all corals respond the same to changes in climate. The University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study looked at the sensitivity of two types of corals found in Florida and the Caribbean and found that one of them—mountainous star coral—possesses an adaptation that allows it to survive under high temperatures and acidity conditions.

“Stressful periods of high temperature and increasingly acidic conditions are becoming more frequent and longer lasting in Florida waters,” said Chris Langdon, marine biology and ecology professor and lead author on the new study. “However, we found that not all coral species are equally sensitive to climate change and there’s hope that some species that seemed doomed may yet develop adaptations that will allow them to survive as well.”

ATLANTIC ‘TRIPOLE’ OF OCEAN TEMPERATURES DRIVING HURRICANE SEASON AND EUROPE’S CRAZY SUMMER

by Joe d’Aleo, August 3, 2018 in WUWT


It has been for northern Europe a hot summer. Is it climate change as the media would like to have us believe? Or, is it something much simpler? For example, ocean patterns. Off the coast of Africa, water was coldest in the entire record back to 1950. A temperature change in one place of the oceans, means a change elsewhere also.

The UK July ranked 3rd warmest since 1950 in the very long term (starting 1659) temperature data-base from Central England.

Old mining techniques make a new way to recycle lithium batteries

by Michigan Technological University, August 2, 2018 in ScienceDaily


Using 100-year-old minerals processing methods, chemical engineering students have found a solution to a looming 21st-century problem: how to economically recycle lithium ion batteries.

Pan, an assistant professor of chemical engineering at Michigan Technological University, earned his graduate degrees in mining engineering. It was his idea to adapt 20th century mining technology to recycle lithium ion batteries, from the small ones in cell phones to the multi-kilowatt models that power electric cars. Pan figured the same technologies used to separate metal from ore could be applied to spent batteries. So he gave his students a crash course in basic minerals processing methods and set them loose in the lab.

Polar Bear Dies, National Geographic Lies

by Donna Laframboise, August 3,  2018 in BigPictureNews


SPOTLIGHT: The iconic magazine is now a purveyor of propaganda.

BIG PICTURE: On her PolarBearScience.com blog last week, zoologist Susan Crockford called our attention to a startling admission over at National Geographic. It acknowledges publishing fake news. Or, as it more delicately puts it, we “went too far in drawing a definitive connection between climate change and a particular starving polar bear.”

An “Editor’s Note” explains the magazine added a wholly misleading caption to a video of an emaciated polar bear filmed last August. When it published this video on its website in December, National Geographic declared: “This is what climate change looks like.”

Actually, this is what dishonesty looks like. Neither the magazine nor the person who did the filming knew anything about that bear. It might have been stricken with disease. It might have sustained an injury that impeded its ability to hunt. As the Editor’s Note now admits: “there is no way to know for certain why this bear was on the verge of death.”
