Solar dimming/brightening effect over the Mediterranean1979 − 2012

Written by H.D. Kambezidisa, D.G. Kaskaoutisa, et al.

Abstract: Numerous studies have shown that the solar radiation reaching the Earth’s surface is subjected to multi-decadal variations with significant spatial and temporal heterogeneities in both magnitude and sign. Although several studies have examined the solar radiation trends over Europe, North America and Asia, the Mediterranean Basin has not been studied extensively.

This work investigates the evolution and trends in the surface net short-wave radiation (NSWR, surface solar radiation – reflected) over the Mediterranean Basin during the period 1979 − 2012 using monthly re-analysis datasets from the Modern Era Retrospective-Analysis for Research and Applications (MERRA) and aims to shed light on the specific role of clouds on the NSWR trends.

The solar dimming/brightening phenomenon is temporally and spatially analyzed over the Mediterranean Basin. The spatially-averaged NSWR over the whole Mediterranean Basin was found to increase in MERRA by +0.36 Wm−2 per decade, with higher rates over the western Mediterranean (+0.82 Wm−2 per decade), and especially during spring (March-April-May; +1.3 Wm−2 per decade). However, statistically significant trends in NSWR either for all-sky or clean-sky conditions are observed only in May.

The increasing trends in NSWR are mostly associated with decreasing ones in cloud optical depth (COD), especially for the low (<700 hPa) clouds. The decreasing COD trends (less opaque clouds and/or decrease in absolute cloudiness) are more pronounced during spring, thus controlling the increasing tendency in NSWR.

The NSWR trends for cloudless (clear) skies are influenced by changes in the water-vapor content or even variations in surface albedo to a lesser degree, whereas aerosols are temporally constant in MERRA. The slight negative trend (not statistically significant) in NSWR under clear skies for nearly all months and seasons implies a slight increasing trend in water vapor under a warming and more humid climatic scenario over the Mediterranean.

Scientists: Climate Models Fail When Trying to Simulate Human Impacts

Written by Kenneth Richard

According to a recently published paper in the journal Science, (Cook et al., 2016, “Ocean forcing of glacier retreat in the western Antarctic Peninsula”), between 1945 and 2009 the mean ocean temperature warmed at depths of 150 to 400 meters for about 3/4ths of the waters surrounding the western Antarctic Peninsula (AP).  The other 1/4th of the ocean waters at those depths (150 to 400 m) cooled (by -1°C ) during  those 65 years.

antarctica-cooling-oceans-cook16-1945-2009

As the authors point out, and as the graph above shows, in the areas where the waters warmed (light red shaded), glacier retreat was observed to be most pronounced (blood red points).  In the regions (Bransfield Strait) where the ocean waters cooled (blue shaded), glaciers were in balance and even advanced (blue points).  Citing this strong correlation between regional ocean warming/cooling and regional glacier retreat/advance, the authors concluded that the long-held assumption that atmospheric and surface  warming (presumably driven by greenhouse gases) was what primarily caused Antarctic glaciers to recede is not supported by the evidence.  Instead, it is the temperature of the ocean waters that “have been the predominant control on multidecadal glacier front behavior in the western AP.”

Is Stupidity A Dangerous Side Effect Of Big-Data-Driven AI?

Written by Bernard Marr

At one time, math teachers everywhere answered the age-old, “but when am I ever going to NEED this?” question by remarking that we wouldn’t carry around calculators in our pockets for the rest of our lives.

And yet, every smartphone (and many remaining “dumb” phones) have calculators built in as one of the simplest apps.

ai

So, does that mean we no longer have to memorize our multiplication tables?

Machines have always existed to make our life easier, but that can have unintended consequences. For example, after the Industrial Revolution, when machines took over much of the manual labor, there was a noticeable increase in weight gain, obesity, and obesity-related diseases.  That has only increased as our jobs have moved us towards even more sedentary lifestyles, sitting at a desk all day.

Experts say California is in a permanent drought, caused by global warming and disappearing Arctic ice.

Precipitation there was above normal over the past 12 months, and there has been no trend over the past 120 years.

CO2 and Climate Change For the Ages

Written by Ron Clutz

An Historical, not Hysterical Perspective: Much of the hysteria over atmospheric CO2 arises from dismissing the past, and thus losing the context for interpreting the present.  Recently, one scientist suggested that climate researchers should be schooled in geology before commenting on climate change.  Instead of that, of course, most of them are based in environmentalism.  So as a public service this post presents some excellent and time-tested evidence produced by Dr Guy LeBlanc Smith.  h/t Jeff Hayes

Britain’s ‘Bonfire’ of Climate & Green Regulations post-Brexit

Written by John O'Sullivan

As the political fall out from Brexit continues Britain’s mainstream media are reporting that environmentalists and climate alarmists are in full panic mode. The growing fear is that the UK government is set on a course of wholesale reversals of pro-green legislation.

greenies

Today’s Independent newspaper (October 13, 2016) reports that the latest “bonfire” fears stem from newly-installed Prime Minister Theresa May’s first act –  to unceremoniously scrap the Department for Energy and Climate Change, merging it into the renamed Department for Business, Energy and Industrial Strategy (BEIS). In no uncertain terms this is seen by all sides as a huge blow to the green lobby. The issue of a successful Brexit seems pinned to appeasing populist demands in abandoning failed and needless environmental policy.

A worried Simon Bullock, a climate campaigner at Friends of the Earth, told The Independent that “some politicians would see Brexit as an opportunity to do away with climate change policies they regard as “wasteful, bureaucratic red tape”.”

Are Global Warming Alarmists Upset Hurricane Matthew Wasn’t Worse?

Written by Kerry Jackson

Chicago mayor and Clinton crony Rahm Emanuel famously said to never let a crisis go to waste in politics. In the case of Hurricane Matthew, some political operatives and global warming true believers might have wanted the crisis to be worse than it was. It would be consistent with their history.

hurricane

Hurricane Matthew killed at least 30 Americans and more than 1,000 in total. Damage is estimated to be at least $5 billion.

But apparently that’s not enough death and destruction for the alarmists.

Before Matthew made landfall Saturday in South Carolina, it had been more than 4,000 days since the last hurricane hit the U.S. That’s 10 years, 11 months and about a week.

New Planet Found in our Solar System by Astronomers

Written by Andrew Follett

Astronomers announced the discovery of a new dwarf planet orbiting the sun in the region beyond Pluto Tuesday. The new planet, dubbed 2014 UZ224, is more than 8.5 billion miles from the sun and has a diameter of about 330 meters.

planet

Uz224 was discovered by Dr. David Gerdes, a professor of astronomy at the University of Michigan. Gerdes used an instrument called a Dark Energy Camera paid for by the U.S. Department of Energy to make maps of distant galaxies.

Gerdes used the camera to photograph small patches of the sky once per week. Stars and galaxies were so much further away than UZ224 that they appeared to be basically stationary. But the tiny planet was continually in a slightly different position as it was moving across the relatively stationary backdrop of stars.

New paper: Solar Cosmic Rays and Climate

Written by Oliver K. Manuel and Golden Hwaung

Abstract: The purpose of this paper is to show the public solar cosmic rays irradiated the early solar system after its birth five billion years (5 Ga) ago, still do, and influence Earth’s climate today. Cosmic rays are one of many ways the Sun’s pulsar core maintains invisible contact with atoms, lives and planets in the solar system. Cosmic rays produce tracks of ion pairs (charge separation) on traversing Earth’s atmosphere. The attractive force of water vapor condensation into water droplets along ion tracks produces electrically charged clouds, rain, lightning and thunder as frequent reminders a solar pulsar controls human destinycosmic-rays

NASA Space Telescope Just Went To Testing — 7 Years Behind Schedule

Written by Andrew Follett

NASA finally began preparing the James Webb Space Telescope (JWST) for testing Thursday, but the project is way behind schedule and over budget.

New video shows the telescope being moved onto a mobile stand for testing, but the project was slated to be in space by 2011. NASA announced last December that the JWST was halfway completed, but the project is currently $7.2 billion over its initial budget and seven years behind the original schedule. The JWST was initially projected to cost $1.6 billion.

The Government Accountability Office now estimates the final cost at $8.8 billion, and NASA has now scheduled the telescope for an October 2018 launch, adding to the telescope’s long history of major cost overruns and delays.

Hurricane Matthew: Apocalypse Not Now

Written by Lloyd Marcus

My wife Mary and I live in central Florida. Hurricane Matthew was expected to hit us around 8am Friday morning. Around 5pm Thursday, I decided to pick up a few groceries. It was too late. Every supermarket was closed. Streets were empty. It felt like I was driving on the set of a sci-fi movie.

We lost power 10pm Thursday night. Mid-morning Friday, the worst of the storm had passed us. Thank God we only lost one tree, which missed our house, and one section of our fence.

hurricane

Mary and I took a ride to assess neighborhood damage. The streets were empty. A picture window was smashed at the corner food mart/gas station. We suspected it was the result of thug damage rather than hurricane damage. We saw three young black guys with their pants below their butts approaching. Accuse me of profiling, but my instincts told me they were up to no good. Sure enough, they spotted the broken window and made a beeline to it. I told Mary to video them with her phone. My foot hovered above the gas pedal for a fast getaway. When the thugs saw Mary shooting them, they wandered away. Mary called the emergency number posted on the store window.

Is our world a simulation? Why some scientists say it’s more likely than not

Written by Olivia Solon

When Elon Musk isn’t outlining plans to use his massive rocket to leave a decaying Planet Earth and colonize Mars, he sometimes talks about his belief that Earth isn’t even real and we probably live in a computer simulation.

“There’s a billion to one chance we’re living in base reality,” he said at a conference in June.

Musk is just one of the people in Silicon Valley to take a keen interest in the “simulation hypothesis”, which argues that what we experience as reality is actually a giant computer simulation created by a more sophisticated intelligence. If it sounds a lot like The Matrix, that’s because it is.

According to this week’s New Yorker profile of Y Combinator venture capitalist Sam Altman, there are two tech billionaires secretly engaging scientists to work on breaking us out of the simulation. But what does this mean? And what evidence is there that we are, in fact, living in The Matrix?

Martians Fine Dining ….. on Lettuce and Cabbage

Written by Dr Klaus L E Kaiser

… and, perhaps, also radishes, snow peas, chard, and tomatoes – all for your balanced diet when dining on Mars.

Those are the plants that the current investigators at NASA think that you may be able to grow on planet Mars, provided these plants can be grown there at all. That’s why NASA is studying the subject at the Kennedy Space Center in Florida. Of course, they have high level backing from the White House that is fostering this week’s conference on “White House Frontiers: Robots, Space Exploration, and the Future of American Innovation.” The conference has five main themes, one of which is “Interplanetary Frontiers.” What could possibly be wrong, or go wrong?

Miracles And Knowledge Of Cause

Written by William M Briggs

gerard_david_-_the_marriage_at_cana_-_wga6020

Jesus turned barrels of water into wine, and good wine at that. Not a drop or two, but large pots, and in only a moment. The details might be important.

Jesus told them, “Fill the jars with water.” So they filled them to the brim. Then he told them, “Draw some out now and take it to the headwaiter.” So they took it. And when the headwaiter tasted the water that had become wine…

Evidently, Jesus never touched the jars. As soon as they were filled, the water in them turned to wine (though it’s possible the water turned to wine in the ladles). The time this took must have been short. A moment or two, tops.

This happened, so it had to happen some how. The question is how? If we have any physicists or chemists in the audience, perhaps they might take a guess. (If you say it didn’t happen, then suppose it did arguendo. Do not go on about how it didn’t.)

Comical Errors in new Book Embarrass Climate Change Authors

Written by Geoff Chambers

It’s not often in the crazy world of Climate Science that you find something wholly new, even crazier than the last crazy thing you read, and written by one of the most prominent climate crazies of all. I’m talking about “Climate Change Science: A Modern Synthesis: Volume 1 – The Physical Climate (2013)” by G. Thomas Farmer and John Cook. You can read extracts of it on Amazon or at Google Books. book

If we haven’t heard more of this 600 page monster (or of volume 2, which was also due out in 2013 but doesn’t seem to have appeared) it’s possibly because of its price ($119).

Editors Springer describe it thus: (the punctuation is theirs):

Volume One of a two-volume treatment of climate change science designed for an introductory science course

Describes the discipline of Climate Change Science, and individual climate change scientists whose expertise spans Earth history, geology, geography, biology, oceanography, astronomy, mathematics, physics, chemistry, engineering and more

Examines evidence of global warming that has entered mainstream discussions of climate change

Discusses the ideas and tactics of climate skeptics and deniers

New paper: Tibet climate change Natural for Last 300 Years

Written by Shiyuan Shi, Jinbao Li et al.

‘Three centuries of winter temperature change on the southeastern Tibetan Plateau and its relationship with the Atlantic Multidecadal Oscillation’ studied in new paper.

tibet

Abstract

Long-term, high-resolution proxy records containing cold season temperature signals are scarce on the southeastern Tibetan Plateau (TP), limiting our understanding of regional climate and the potential driving forces. In this study, we present a nearly three centuries long reconstruction of winter (December–February) mean temperature for the central Hengduan Mountains, southeastern TP. The reconstruction is derived from a composite tree-ring width chronology of Pinus yunnanensis Franch from two high elevation sites (>3000 m above sea level). Our reconstruction passes all standard calibration-verification schemes and explains nearly 73 {154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the variance of the original instrumental data. However, we were constrained to calibrate our full period (1718–2013) reconstruction of December–February mean temperature on the calibration period from 1959 to 1992 only, due to a decrease in temperature sensitivity of tree-ring index exhibited after 1992. Spatial correlation analysis shows that our reconstruction represents large-scale temperature variations in southwest China and the eastern TP. Our reconstructed December–February mean temperature shows a close association with the Atlantic Multidecadal Oscillation (AMO) over the past three centuries, with warm (cold) periods coinciding with the positive (negative) phases of the AMO. This persistent relationship suggests that the AMO may have been a key driver of multidecadal winter temperature variations on the southeastern TP.
