Scientists have discovered what they say could be fossils of some of the earliest living organisms on Earth. They are represented by tiny filaments, knobs and tubes in Canadian rocks dated to be up to 4.28 billion years old.

That is a time not long after the planet’s formation and hundreds of millions of years before what is currently accepted as evidence for the most ancient life yet found on Earth.The researchers report their investigation in the journal Nature.

Fox TV Climate Debate: It didn’t end well for the ‘Science Guy’

Written by Julie Kelly

Climate-change alarmists who have been largely unchallenged by the media over the past decade have finally met their match in Fox News host Tucker Carlson. And it ain’t pretty.

Since the premiere of his new nighttime show, Carlson has frequently confronted the dogma of man-made global warming, pushing “experts” to cite data and evidence to back up their claims rather than allowing them to repeat well-worn platitudes about a scientific consensus and the planet’s impending doom.

Japanese Expert: Models Just Cartoon Climate Science

Written by John O'Sullivan

As U.S. President Donald Trump works towards deep cuts to federal funding for climate research an independent Japanese climate researcher shows why climate modeling was really junk science all along.

Kyoji Kimoto, a retired expert in fuel cell energy and thermodynamics, points to recent evidence to prove a statistical “hoax” in a heated email exchange with a top UN climate modeler, Dr Robert D Cess of Stony Brook University, New York.

Global Warming? It Just Ain’t So!

Written by Nick Schroeder, BSME, PE

Will Rogers (and Mark Twain) observed, “It’s not ignorance that is the problem, but that so much of what we know just ain’t so.” Adding to the “33C without an atmosphere” that is completely wrong is the case of Venus.
Venus, we are told, has an atmosphere that is almost pure carbon dioxide and an extremely high surface temperature, 750 K, and this is allegedly due to the radiative greenhouse effect, RGHE. But the only apparent defense is, “Well, WHAT else could it BE?!”

Atomic future may prove a reality for Africa

Written by Gavin du Venage

A dire shortage of electricity could mean Africa’s emerging economies turn to nuclear to underpin industrial growth. This would be a neat fit, considering Africa is where the nuclear age had its origins.

The raw material used for nuclear development during the Second World War was sourced in what was then the Belgian Congo. Africa is also where one of the world’s only natural reactors is found – geologists stumbled on a uranium deposit in Gabon that was found to have developed self-sustaining nuclear reaction aeons ago, and remained active for millennia.

Neanderthal DNA contributes to human gene expression

Written by Cell Press

The last Neanderthal died 40,000 years ago, but much of their genome lives on, in bits and pieces, through modern humans. The impact of Neanderthals’ genetic contribution has been uncertain: Do these snippets affect our genome’s function, or are they just silent passengers along for the ride?

In Cell on February 23, researchers report evidence that Neanderthal DNA sequences still influence how genes are turned on or off in modern humans. Neanderthal genes’ effects on gene expression likely contribute to traits such as height and susceptibility to schizophrenia or lupus, the researchers found.

Deadly stars: Our sun could also be superflare star

Written by Aarhus University

Earth is often struck by solar eruptions. These eruptions consist of energetic particles that are hurled away from the Sun into space, where those directed towards Earth encounter the magnetic field around our planet.

When these eruptions interact with Earth’s magnetic field they cause beautiful auroras. A poetic phenomenon that reminds us, that our closest star is an unpredictable neighbor.

The connected city never sleeps. The thousands of sensors embedded in roads, sewers, water pipes, streetlights are busy collecting information day and night. Perhaps even your bin, which might also be tweeting.

Sensor provider Enevo offers internet connection for bins in cities in Finland, the Netherlands, UK, Belgium, Canada and the US, and runs a Twitter feed – Trashcan Life.

Simultaneous Conduction and Radiation Energy Transfer

Written by Pierre R Latour PhD, PE, Chemical Process Control Engineer

Radiant energy can transfer from a colder to a warmer radiator.

Abstract: The rigorous model of simultaneous thermal and radiant energy transfer proves energy transfer by radiation can flow from a colder radiator to a warmer one, heating the warmer one further. It explains and quantifies how dissimilar walls in a room can have different steady-state temperatures.

Only the general laws of thermal and radiant energy transfer and the First Law of Thermodynamics, conservation of energy, are employed. [Editor’s note: since publication PSI has negatively reviewed this post*]

Introduction: Many claim radiant energy can only transfer from a hot radiator to a colder one. Otherwise the Second Law of Thermodynamics would be violated.

Undermining Academic Achievement in America

Written by Walter E. Williams

According to The Nation’s Report Card, only 37 percent of American 12th-graders were proficient in reading in 2015, and just 25 percent were proficient in math (https://www.nationsreportcard.gov). For black students, achievement levels were a disgrace.

Nationally, 17 percent of black students scored proficient in reading, and 7 percent scored proficient in math. In some cities, such as Detroit, black academic proficiency is worse; among eighth-graders, only 4 percent were proficient in math, and only 7 percent were proficient in reading.

Elon Musk, it seems, loves nothing more than to spin plates. When most of us might be looking to lighten the load, he’s piling on the ambition.

The serial entrepreneur’s latest gambit is to fly people around the Moon. Two wealthy individuals have apparently lodged significant deposits with his SpaceX company to make this journey. We have no idea who they are, just that these space tourists include “nobody from Hollywood”.

‘To be 33C or not to be 33C’ Greenhouse Gas Fallacy Exposed

Written by Nick Schroeder, BSME, PE

There is a popular fantasy that the earth is 33C warmer with an atmosphere than without due to the radiative greenhouse effect, RGHE and .04{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} CO2.  Let’s start at the very beginning, a very good place to start – or so I hear.

The 33C difference is between an alleged average surface temperature of 288K/15C and 255K/-18C, the alleged surface temperature without an atmosphere. Let’s take a closer look. Just which average surface temperature? The two extremes? (71C + -90C) / 2 = -10C?

Blue-eyed humans have a single, common ancestor

Written by University of Copenhagen

New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.

Climate Science and Climatology; Specialization and Generalization; Forest and Trees

Written by Dr Tim Ball

Many jumped to the defense of Dr. John Bates, the former NOAA employee who waited until he retired to disclose malfeasance in the science and management at that agency. Bates claimed he told his bosses about the problem but said they effectively ignored him.

The problem is everything was already in the public record. I listened to Congressman Lamar Smith tell the general audience at the June 2015 Heartland Conference that subpoenas were filed requesting full disclosure of all the material. He also told us the requests were rejected, but a follow-up was in progress. The same information was reported in the mainstream media, albeit with a bias.

The Delusional War on Warmth

Written by Viv Forbes

For decades, global warming scaremongers have been stealing energy from the environment using windmills, solar collectors, and biofuels, force-fed by carbon taxes and emission trading schemes.  Their delusional dream is to cool the globe.

However, there has been no global warming for nearly 20 years.  Right now, the great ice sheets are growing thicker, and record snow is blanketing much of the climate change leader, the Northern Hemisphere landmass.  Solar panels are blinded by snow, and turbines don’t turn in the cold still air, or else they have to be shut down because of icing or high winds.  Like all green things, wind and solar power often hibernate in winter.

Radiation Physics Laws Give the Effect of CO2 on Earth’s Temperatures – A Primer

Written by Pierre R Latour PhD, PE, Chemical Process Control Engineer

Abstract: A new chemical process control systems engineering model of Earth’s atmosphere quantifies the effect of CO2 on Earth’s surface temperature. It uses the rigorous S-B radiant energy transfer rate law. The Earth’s surface and atmospheric temperatures are given explicitly as linear ordinary differential and algebraic equations; the only system properties needed are absorptivity and emissivity, five of which depend on CO2.

CO2 affects surface temperature by at least four mechanisms, one positive and three negative. CO2 decreases Earth’s global radiating temperature to space slightly. When atmosphere parameters increase by 1{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} due to CO2, surface temperature changes – 0.762C and atmosphere changes – 0.392C.
