January temperatures (preliminary)
Global composite temp.: +0.72 C (about 1.3 degrees Fahrenheit) above 20-year average for January.
Northern Hemisphere: +0.84 C (about 1.51 degrees Fahrenheit) above 20-year average for January.
Southern Hemisphere: +0.61 C (about 1.1 degrees Fahreneheit) above 20-year average for January.
December temperatures (revised):
Global Composite: +0.29 C above 20-year average
Northern Hemisphere: +0.33 C above 20-year average
Southern Hemisphere: +0.25 C above 20-year average
(All temperature anomalies are based on a 20-year average (1979-1998) for the month reported.)
Notes on data released Feb. 10, 2010:
A large El Nino Pacific Ocean warming event exposed the atmosphere to enough extra heat energy to cause the warmest January and the third warmest month overall in 32 years, and the warmest month in almost a decade (compared to seasonal norms), according to Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville.
"This has the potential of breaking the records set in February and April 1998, during the 'El Nino of the Century,'" Christy said. "I looked at sea surface temperatures in the Central Pacific and it wasn't as warm as 1998, but what is there is spread out further than it was in 1998. That exposes the atmosphere to a lot of extra heat."Hottest months in the 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.For Additional Information:

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
