Another Attempt To Find The Tropical Hotspot!

In his latest rant against deniers, David Holub referred to an article in the Guardian which was, even by their standards, particularly misleading.


Written by the notoriously unreliable John Abraham, it says:

A very important study was just published in the Journal of Climate a few days ago. This paper, in my mind, makes a major step toward reconciling differences in satellite temperature records of the mid-troposphere region. As before, it is found that the scientists (and politicians) who have cast doubt on global warming in the past are shown to be outliers because of bias in their results.

It is known that there is a problem because there are multiple groups that create satellite temperature records. For instance, NOAA, Remote Sensing Systems (RSS), and the University of Alabama Huntsville (UAH). The problem is, their results don’t agree with each other. In particular, the…

Definition of ‘climate’ changing faster than at any time in last 1000 years


It’s worse than we thought ;)

According to an alarming new analysis of the climate corpus, natural concept change can’t account for the dramatic saltations we’re witnessing in what scientists say the Earth’s climate means.

Climate philologists say the motion of the dial far exceeds background rates of semantic drift, and shows no sign of damping. They’re now worried that—with recent disturbances in weather,consensus,acidification,pollution,skeptic,global,conspiracist,conspiratorial,trick,hide,what the peer-reviewed literature is,the scientific method,knowledge,evidence and other traditionally stable concepts—verbal weirding could represent a new normal.

Stefan Lewandowsky, Bristol University’s Professor of Cognitive Science and a regular CN contributor, doesn’t need to see the data. He’s well aware that things are getting more frequent, because it’s happening to him. Anecdotally. It’s not unusual now, says Lewandowsky, to start work on a cli-psy paper and have no idea what a familiar and well-defined term will…

NASA is using a 21st century version of schlieren imagery, invented by a German physicist in 1864, to visualize supersonic flow phenomena with full-scale aircraft in flight.

NASA researchers in California are using a modern version of a 150-year-old German photography technique to capture images of shock waves created by supersonic airplanes. Over the past five years scientists from NASA’s Armstrong Flight Research Center at Edwards Air Force Base and Ames Research Center at Moffett Field have teamed up to demonstrate how schlieren imagery, invented in 1864 by…

A layer of carbon can bestow the powers of magnetism. Viviane Richter explains.

In a feat of modern day alchemy, scientists have successfully turned non-magnetic metals into magnets. Oscar Cespedes at the University of Leeds and his team published their magnetic recipe in Nature in August. The key ingredient? A dusting of carbon.

“This is a new way of making magnets – it opens up a new field!” says Naresh Dalal from Florida State University, who also researches magnetic materials.

Magnets are crucial in the age of big data. We’ve generated almost as much data in the past two years as during all of human history. To generate and…

Hurricane expert: 10 years after Katrina, North Atlantic hurricane activity well below normal

Originally posted on Watts Up With That?:

Noted hurricane expert Dr. Philip Klotzbach of Colorado State University has had some interesting discussion and stats on his Twitter feed, for example:

10 years ago today, TD 10’s remnants brewed north of Hispaniola. 8 days later, Katrina was a Category 5 in the Gulf.

hurricane-danny-iss Hurricane Danny, the first hurricane of the 2015 Atlantic season, is seen in this picture taken by NASA astronaut Scott Kelly taken from the International Space Station Thursday.

It is worth noting that 2005 had 11 named storms, seven of which hit land and five of which caused major damage. In contrast to that era, we’ve recently seen the fourth named storm in the Atlantic, Hurricane Danny, fizzle out back to tropical storm status last Saturday, and now as a tropical depression is listed as remnant status by NHC. Given NOAA’s recent update for a below normal season, this isn’t surprising.


The remnants of…

Arctic Amplification?

Originally posted on Science Matters:

Discussions of the Arctic often include references to “Polar Amplification,” defined thusly by climate scientists (wikipedia):

“Polar amplification refers to the observation that any change in the net radiation balance (for example greenhouse intensification) tends to produce a larger change in temperature near the poles than the planetary average.”

NSIDC adds in the notion of positive feedbacks and concern over “tipping points.”

“Scientists have already seen evidence that positive feedbacks are occurring in the Arctic. They call this Arctic amplification. Predicting the Arctic climate is difficult. Some of the changes in the Arctic could also have negative feedback effects, or effects that reduce the amount of warming. For example, if warm temperatures make the Arctic growing season longer, more plants can survive and take up more carbon from the air. However, most evidence suggests that the positive feedback effects outweigh the negative effects. A recent report by NOAA concluded that…

1Diagram of the Lagrange points associated with the sun-Earth system

A Lagrange point is a location in space where the combined gravitational forces of two large bodies, such as Earth and the sun or Earth and the moon, equal the centrifugal force felt by a much smaller third body. The interaction of the forces creates a point of equilibrium where a spacecraft may be “parked” to make observations.

These points are named after Joseph-Louis Lagrange, an 18th-century mathematician who wrote about them in a 1772 paper concerning what he called the “three-body problem.” They are also called Lagrangian points and libration points.

Structure of Lagrange points

There are five Lagrange points around major bodies such as a planet or a star. Three of them lie along the line connecting the two large bodies. In the Earth-sun system, for example, the first point, L1…
