Global composite temp.: +0.18 C (about 0.32 degrees Fahrenheit) above 30-year average for March.
Northern Hemisphere: +0.33 C (about 0.59 degrees Fahrenheit) above 30-year average for March.
Southern Hemisphere: +0.04 C (about 0.07 degrees Fahrenheit) above 30-year average for March.
Tropics: +0.22 C (about 0.40 degrees Fahrenheit) above 30-year average for March.
February temperatures (revised):
Global Composite: +0.18 C above 30-year average
Northern Hemisphere: +0.37 C above 30-year average
Southern Hemisphere: -0.02 C below 30-year average
Tropics: +0.17 C above 30-year average
(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)
Notes on data released April 1, 2013:
Two new climate ‘products’ will soon be available from the UAH temperature dataset, while a long standing product has been improved to make it more accurate, 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 “USA48” data, which tracks month-to-month temperature anomalies and the long-term climate trend over the contiguous 48 states, has been made more accurate by using a more precise tool for including the pieces of land adjacent to oceans.
The two new products are a USA49, which includes Alaska with the lower 48, and a listing for Australia, which includes Tasmania. Both of these new products will include temperature anomaly and trend data going back to the beginning of the UAH dataset in December 1978.
Compared to seasonal norms, during March the coldest area on the globe was in northeastern Russia, where the average temperature was as much as 6.49 C (about 11.7 degrees Fahrenheit) cooler than seasonal norms. Looking at the global anomaly map also shows the eastern U.S. and central Canada becoming much cooler than normal in March.
Compared to seasonal norms, the “warmest” area on the globe in March was middle of the Davis Strait, between Greenland and Baffin Island. Temperatures there averaged 6.49 C (about 11.7 degrees Fahrenheit) warmer than seasonal norms for March.Archived color maps of local temperature anomalies are available on-line at:
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

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
