Global climate trend since Nov. 16, 1978: +0.14 C per decade
March temperatures (preliminary)
Global composite temp.: -0.10 C (about 0.18 degrees Fahrenheit) below 30-year average for March.
Northern Hemisphere: -0.07 C (about 0.13 degrees Fahrenheit) below 30 year average for March.
Southern Hemisphere: -0.13 C (about 0.23 degrees Fahrenheit) above/below 30-year average for March.
Tropics: -0.35 C (about 0.63 degrees Fahrenheit) below 30-year average for March.
February temperatures (revised):
Global Composite: -0.02 C below 30-year average
Northern Hemisphere: -0.04 C below 30-year average
Southern Hemisphere: ±0.00 C above/below 30-year average
Tropics: -0.35 C below 30-year average
(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)
Notes on data released April 5, 2011:
Driven by the La Nina Pacific Ocean cooling event, global average temperatures in March 2011 were the coolest March since 1999, according to Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville.
It was the fifth coolest March in the tropics, where the average temperature fell 0.35 C (about 0.63 degrees Fahrenheit) below seasonal norms. Three of the five coldest tropical Marches in the 33-year satellite temperature record have happened in the past dozen years: 5th, 2011, -0.35 C: 3rd, 2000, -0.42; and 2nd, 2008, -0.58 C.Coldest Marches In the 33-yr Satellite Record
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.Dr. John Christy, (256) 961-7763

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
