A Discussion of the Equations of Transfer

Written by Joseph E Postma

I was having an email discussion with an old professor of mine (from undergad) about the fraud of the radiative greenhouse effect who has himself implied doubt about the greenhouse effect.  Actually the proff is Dr. Essex who wrote the book “Taken by Storm“.  He suggested that I look at the “equations of transfer” in regard to the problem, which of course I have already done extensively and am quite familiar with.  I will post the reply here since it may help some people:

3D-printed ‘bionic skin’ could give robots the sense of touch

Written by University of Minnesota College of Science and Engineering

Engineering researchers at the University of Minnesota have developed a revolutionary process for 3D printing stretchable electronic sensory devices that could give robots the ability to feel their environment. The discovery is also a major step forward in printing electronics on real human skin.

How hard did it rain on Mars?

Written by Elsevier

Heavy rain on Mars reshaped the planet’s impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet’s surface as we see on Earth.

Space weather events linked to human activity

Written by NASA/Goddard Space Flight Center

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather — which can include changes in Earth’s magnetic environment — are usually triggered by the sun’s activity, but recently declassified data on high-altitude nuclear explosion tests have provided a new look at the mechansisms that set off perturbations in that magnetic system. Such information can help support NASA’s efforts to protect satellites and astronauts from the natural radiation inherent in space.

Dinosaur asteroid hit ‘worst possible place’

Scientists who drilled into the impact crater associated with the demise of the dinosaurs summarise their findings so far in a BBC Two documentary on Monday. The researchers recovered rocks from under the Gulf of Mexico that were hit by an asteroid 66 million years ago. The nature of this material records the details of the event. It is becoming clear that the 15km-wide asteroid could not have hit a worse place on Earth.

12 surprising facts about earthquakes

Written by bbc.co.uk

1. There are several million earthquakes annually

According to the United States Geological Survey, there are around 17 major earthquakes measuring above 7.0 on the Richter scale – and one great earthquake measuring above 8.0 – each year. However, experts estimate that there are actually several million earthquakes annually; many go undetected due to their geographical remoteness or small magnitude.

2. An earthquake can affect the length of a day

On 11 March 2009, an 8.9 magnitude earthquake which struck northeast Japan altered the distribution of the earth’s mass, causing it to rotate slightly faster, and shortening an earth day by around 1.8 microseconds.

GLOBAL GREENING: Scientists Find ‘Lost’ Forests The Size Of Seven Texases

Written by Michael Bastach

Scientists looking at forest cover in some of the world’s driest places found something astounding — “lost” forests covering an area nearly seven times the size of Texas.

“We found new dryland forest on all inhabited continents, but mainly in sub-Saharan Africa, around the Mediterranean, central India, coastal Australia, western South America, northeastern Brazil, northern Colombia and Venezuela, and northern parts of the boreal forests in Canada and Russia,” biologists Andrew Lowe and Ben Sparrow wrote of their study, which had 28 other co-authors.

Humans rely more on ‘inferred’ visual objects than ‘real’ ones

Written by eLife

Humans treat ‘inferred’ visual objects generated by the brain as more reliable than external images from the real world, according to new research published in eLife.

The study, from the University of Osnabrück, Germany, reveals that when choosing between two identical visual objects — one generated internally based on information from the blind spot and an external one — we are surprisingly likely to show a bias towards the internal information.

Green Energy, Sunny Roof Tiles and Boring Tunnels

Written by Dr Klaus L E Kaiser

Well, on the surface, the recently touted “solar roof tiles” sound like a great idea, a roof with photovoltaic cells embedded in the tiles, barely distinguishable from ordinary roof tiles.

So, for the moment, let’s forget about the cost of the tiles and their installation, neither of which is exactly “peanuts.” There are other problems as well, like:

15 New Studies Abandon Claims of Man-Made Influence On Arctic Climate

Written by Kenneth Richard

Gajewski, 2015

Natural Forcing Of Arctic Climate Increasingly Affirmed By Scientists

Three years ago a cogent paper was published in the prestigious scientific journal Nature that was surprisingly candid in its rejection of the position that the substantial warming and sea ice reduction in the Arctic occurring since the late 1970s should be predominantly attributed to anthropogenic forcing.

Dr. Quinhua Ding and 6 co-authors indicated in their paper that internal processes — natural variability associated with planetary waves and the North Atlantic Oscillation — are drivers of the recent Arctic warming and sea ice reduction, concluding that “a substantial portion of recent warming in the northeastern Canada and Greenland sector of the Arctic arises from unforced natural variability.”

Dangerous Cosmic Rays on the Rise as Solar Minimum Approaches

Written by Meteorologist Paul Dorian

The sun is spotless again today which makes 6 days in a row and marks the 36th day this year – already more than all of 2016.

Overview
Today marks the 6th day in a row that the sun is blank and the 36th time this year – already more spotless days than all of 2016.   In what has turned out to be a historically weak solar cycle (#24), the sun continues to transition away from its solar maximum phase and towards the next solar minimum.

Universities Lying to Students about ‘Sustainable Farming’

Written by Henry I Miller

‘Sustainable’ has become a buzzword applicable not only to agriculture and energy production but to sectors as far afield as the building and textile industries. Many large companies tout the concept and boast a sustainability department, and the United Nations has hundreds of projects concerned with sustainability throughout its many agencies and programs.
