Notes on data released June 11, 2014:

May 2014 was the third warmest May in the 35-year satellite-measured global temperature record, and the warmest May that wasn’t during an El Niño Pacific Ocean warming event, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville. The global average temperature for May was 0.33 C (about 0.59 degrees Fahrenheit) warmer than seasonal norms for the month. The warmest May was in 1998, during the “El Niño of the century.” Temperatures in May 1998 were 0.56 C (about 1.0 degrees F) warmer than normal. May 2010 — also an El Niño month — was second warmest at 0.45 C (0.81 degrees F).

While May 2014 was not officially an El Niño month, indications are that an El Niño is forming in the eastern central Pacific off the equatorial coast of South America. Even if that El Niño is nothing spectacular, it might become a record setter simply because it is getting a warmer start, Christy said. “The long-term baseline temperature is about three tens of a degree (C) warmer than it was when the big El Niño of 1997-1998 began, and that event set the one-month record with an average global temperature that was 0.66 C (almost 1.2 degrees F) warmer than normal in April 1998.”

January through August of 1998 are all in the 14 warmest months in the satellite record, and that El Niño started when global temperatures were somewhat chilled; the global average temperature in May 1997 was 0.14 C (about 0.25 degrees F) cooler than the long-term seasonal norm for May.

“With the baseline so much warmer, this upcoming El Niño won’t have very far to go to break that 0.66 C record,” Christy said. “That isn’t to say it will, but even an average-sized warming event will have a chance to get close to that level.”

Compared to seasonal norms, the coldest place in Earth's atmosphere in May was over the northern Pacific Ocean, where temperatures were as much as 2.08 C (about 3.74 degrees Fahrenheit) cooler than seasonal norms. Compared to seasonal norms, the warmest departure from average in May was along the western border of Kazakhstan. Temperatures there were as much as 4.18 C (about 7.52 degrees Fahrenheit) warmer than seasonal norms.

As part of an ongoing joint project between UAH, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.

Neither Christy nor Spencer receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups. All of their climate research funding comes from federal and state grants or contracts.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
