New Paper: Role of greenhouse gases in climate change

Written by PSI staff

Abstract:  This study examines the concept of ‘greenhouse gases’ and various definitions of the phenomenon known as the ‘Atmospheric Radiative Greenhouse Effect’. The six most quoted descriptions are as follows: (a) radiation trapped between the Earth’s surface and its atmosphere; (b) the insulating blanket of the atmosphere that keeps the Earth warm; (c) back radiation from the atmosphere to the Earth’s surface; (d) Infra Red absorbing gases that hinder radiative cooling and keep the surface warmer than it would otherwise be – known as ‘otherwise radiation’; (e) differences between actual surface temperatures of the Earth (as also observed on Venus) and those based on calculations; (f) any gas that absorbs infrared radiation emitted from the Earth’s surface towards free space.

Tsunami formation: Study challenges long-held theory

Written by NASA/Jet Propulsion Laboratory

A new NASA study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor.

An undisputed fact was that most tsunamis result from a massive shifting of the seafloor — usually from the subduction, or sliding, of one tectonic plate under another during an earthquake.

Why the People’s Climate March Is a Farce

Written by Thomas Richard

….  The next time a warmist starts blathering on about carbon pollution, hand him a glass of tonic water and say “Here, have some carbon pollution.” Yes, that seltzer water contains plenty of the dreaded carbon dioxide. And because the media have warned of “carbon pollution” so often, the public now confuses CO2 with perceived soot emissions. But America’s modern coal-fired power plants use advanced scrubbers to remove mercury, nitrous oxide, sulfates, and particulate matter, leaving only a mixture of water vapor and carbon dioxide to rise up the “smokestack.” Of course, CO2 is also a key nutrient for all plant life and, according to NASA, is making the Earth greener.

Technology and the threat of a jobless future

Written by Marcello Majonchi

“[The robots] are expanding skills, moving up the corporate ladder, showing awesome productivity and retention rates, and increasingly shoving aside their human counterparts”

You might think — or hope, if you’re a nerd deep inside — that this excerpt belongs to an unpublished novel from Isaac Asimov. Sadly, at least for sci-fi lovers, it actually comes from “The Rise of the Robots”, a book that explores the impact of technology on the future of our society.

Is inequality about to get unimaginably worse?

Written by bbc.co.uk

Could advances in technology, genetics and artificial intelligence lead to a world in which economic inequality turns into biological inequality? asks the historian and writer Yuval Noah Harari. Inequality goes back at least 30,000 years.

Hunter-gatherers were more equal than subsequent societies. They had very little property, and property is a pre-requisite for long-term inequality. But even they had hierarchies. In the 19th and 20th Centuries, however, something changed. Equality became a dominant value in human culture, almost all over the world. Why?

The March for … What?

Written by Joe Bastardi

Another March for Science is tomorrow and no one in their right mind would say they are against it because of its name. First of all, you are standing against the right of people to march for whatever cause they wish. Second, you would be portrayed as someone who is against science.

I am all for science. I think the climate changes. It always has and always will. Yet I have been portrayed as anti-science and a climate change “denier” by many who will be marching for things I certainly believe in.

20 New Science Papers Find Climate is Driven by Solar Changes

Written by Kenneth Richard

Earlier this month, the first installment in the accumulating list of hundreds of new peer-reviewed scientific papers supporting a skeptical position on climate change alarm was made available. Included on the list were 38 papers linking climate changes to solar forcing: 38 Sun-Climate Scientific Papers, January-March 2017

Just in the last few weeks alone, another 20 scientific papers were identified which link solar variations to climate changes, which means 58 papers have already been published in 2017.

The DNA of extinct humans can be retrieved from sediments in caves – even in the absence of skeletal remains. Researchers found the genetic material in sediment samples collected from seven archaeological sites. The remains of ancient humans are often scarce, so the new findings could help scientists learn the identity of inhabitants at sites where only artefacts have been found. The results are described in Science.

New study shows there’s a positive side to worrying

Written by University of California - Riverside

Worry — it does a body good. And, the mind as well. A new paper by Kate Sweeny, psychology professor at the University of California, Riverside, argues there’s an upside to worrying.

“Despite its negative reputation, not all worry is destructive or even futile,” Sweeny said. “It has motivational benefits, and it acts as an emotional buffer.”

Fake science: Aussie Taxpayers Waste $3 million on Unreliable Research

Written by Timna Jacks

Taxpayers have spent more than $3 million on unreliable academic research, as science experts warn that research fraud and plagiarism in Australia is not being properly policed.

Twenty-one research projects largely funded by the federal government breached integrity standards in the past two years, figures from the Australian Research Council reveal. The federal government body, which provides tens of millions of dollars in taxpayer-funded research grants, stopped funding three grants, recovered funding for one grant, and placed restrictions on funding for one researcher.

The role of sleep changes with every stage of life, from infancy to old age. The latest neuroscience is discovering how crucial sleep is to an infant’s growing brain, while the latest epidemiology is discovering how irregular sleep doubles the risk of death as we grow older. To mark National Sleep Week, Thrive Global spoke with some of the top researchers in sleep science to give you a map of how sleep changes through your lifespan.

A British inventor, who built an Iron Man-style flight suit, has flown it at the Ted (Technology, Entertainment and Design) conference in Vancouver. Richard Browning’s short flight took place outside the Vancouver Convention Centre in front of a large crowd.

Since he posted the video of his maiden flight in the UK, Mr Browning has had huge interest in his flying suit. But he insists the project remains “a bit of fun” and is unlikely to become a mainstream method of transportation.

‘First Americans’ claim sparks controversy

A study that claims humans reached the Americas 130,000 years ago – much earlier than previously suggested – has run into controversy. Humans are thought to have arrived in the New World no earlier than 25,000 years ago, so the find would push back the first evidence of settlement by more than 100,000 years. The conclusions rest on analysis of animal bones and tools from California. But many experts contacted by the BBC said they doubted the claims.
