Granada demo open thread

Posted: February 29, 2012 by Rog Tallbloke in Uncategorized

There was a huge demo of around 15-20,000 people in Granada tonight, protesting changes to labour laws and working practices.

The march came down the main street right past our hotel, where I got some snaps from our balcony on the fourth floor. They were using flash powder to set off mighty canon-fire which shook our windows!

Day 5: The Alhambra and a plan for the high Sierra

Posted: February 29, 2012 by Rog Tallbloke in Photography, Travel

The Alhambra is a world famous site on a hill at the edge of Granada. It consists of a sandstone fortress encompassing a range of Moorish palaces, monumental buildings from the 13th to 18th centuries, and the fabulous garden of Generalife. I keep coming back here, but for Kath, it was a first, and I enjoyed seeing her delight and wonder. Here are a few shots from our visit.

Day 4: From coast to mountains

After three beach days, we´ve headed uphill. This was the dawn at Almunecar this morning.

Around midday we headed for the bus station, arriving just in time to catch the fast aircon coach to Granada. It´s a spectacular climb, with the Sierra Nevada eventually dominating the skyline.

This 2008 article holds an important historical truth about the adjustment of ARGO data. I suggest everyone copies and pastes the original article into a text file or saves the web page complete. One day, it will disappear…

Some 3,000 scientific robots that are plying the ocean have sent home a puzzling message. These diving instruments suggest that the oceans have not warmed up at all over the past four or five years. That could mean global warming has taken a breather. Or it could mean scientists aren’t quite understanding what their robots are telling them.

This is puzzling in part because here on the surface of the Earth, the years since 2003 have been some of the hottest on record. But Josh Willis at NASA’s Jet Propulsion Laboratory says the oceans are what really matter when it comes to global warming.

In fact, 80 percent to 90 percent of global warming involves heating up ocean waters. They hold much more heat than the atmosphere can. So Willis has been studying the ocean with a fleet of robotic instruments called the Argo system. The buoys can dive 3,000 feet down and measure ocean temperature. Since the system was fully deployed in 2003, it has recorded no warming of the global oceans.

“There has been a very slight cooling, but not anything really significant,” Willis says. So the buildup of heat on Earth may be on a brief hiatus.

Happy landing in Malaga

Posted: February 25, 2012 by Rog Tallbloke in atmosphere, weather

We had a nice easy flight from Leeds to Malaga. Our accom in the old university hall of residence is great, and very central. After checking in we had a stroll round. The streets are still crowded at midnight. Everyone is out for the first warm saturday night of 2012.

Stefan-Boltzmann Law and the Construction of a Perpetuum Mobile

Hans Jelbring
BSc, meteorologist, Stockholm University, Civil engineer, electronics, Royal Institute of Technology, Stockholm, PhD, institution of Paleogeophysics & geodynamics, Stockholm University

Abstract

By analyzing two concentric spheres where one is placed inside the other some far reaching conclusions can be made concerning temperatures on two concentric spherical surfaces. The volume in between the inside surface of the outer sphere and the outside surface of the inner surface is of interest when there is vacuum in that volume.  These surfaces are assumed to emit electromagnetic radiation according to the Stefan-Bolztmann law. It is shown that the outer spherical surface will be heated by electromagnetic radiation to a temperature above the temperature of the inner surface.  The maximum difference of surface temperatures at power balance will depend on geometry, that is to say the ratio of the spheres.  The result implies that either it is possible to build a simple heat generator by small means for anybody or alternatively the Stefan-Boltzmann law is not applicable in a real world, at least not at close to ambient temperatures where the radiation isn’t directed towards empty space.

The Myth of ‘Backradiation’.

Stephen Wilde

1) The so called ‘consensus’ theory of the Greenhouse Effect.

At some point over the past twenty years or so it has come to be believed that the physics of radiation is the primary driving process for planetary atmospheric temperatures.

I do not know how or when that happened but it is contrary to the settled science that I grew up with some 40 years ago.

The idea is that certain gases in the atmosphere known as Greenhouse Gases absorb and emit more radiation than the other, majority, gases such as Oxygen and Nitrogen which make up the vast bulk of Earth’s atmosphere.

Consequently it is proposed that such Greenhouse Gases block radiation emanating from the Earth’s surface from escaping to space and re- radiate a proportion of such upward radiation back to the surface which then becomes warmer than it otherwise would have done.

That, in essence is the Greenhouse Theory of radiative gases and that underlies the entire proposition that human emissions of CO2 and other similar gases such as Methane are capable of heating up the Earth so as to change climates and ultimately cause devastation.

I’m reblogging this great new post from Harold Ambler, author of ‘Don’t sell your coat’ which we reviewed here on the talkshop recently. Hyperbole in climate journalism numbs the brain…

Handel's Messiah: It's not just for Christmas anymore.

Attention scientists and journalists: I want my word back. You don’t get to use it anymore, unless you want to admit that you are in the business of deceiving people. That word? “Ever.”

I know I’m in for it when I hear this word at home. “You don’t ever…” and “You never” and “You always” – these are statements that I’ve gotten my beloved wife to see seldom accompany truth-telling. What they do accompany is strong feeling.

And you’d need strong feelings to use the word “ever” to describe 150 years in Earth’s history: “Warmest ever,” “third warmest ever,” “hottest ever,” “fifth hottest ever,” “second warmest ever.” Taken as a whole, statements like these, which are found in articles purporting to inform the public, become incantatory, and indeed echo literal hymns sung in literal churches, worldwide: “Forever and ever

The solar polar magnetic field goes through zero at about sunspot cycle maximum, with the magnetic cycle running at half the speed, one reason why alternate sunspot cycles are similar.

The present solar situation is genuinely anomalous with no-one clear on what is going to happen next.
