Global Temperature Report - October 2008

Scientists at The University of Alabama in Huntsville use data gathered by microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth.
Global trend since Nov. 16, 1978:
+0.13 C per decade
October temperatures (preliminary)
Global composite temp.:
+0.17 C (about 0.31° Fahrenheit) above 20-year average for October.
Northern Hemisphere:
+0.26 C (about 0.47° Fahrenheit) above 20-year average for October.
Southern Hemisphere:
+0.07 C (about 0.13° Fahrenheit) above 20-year average for October.
September temperatures (revised):
Global Composite:
+0.16 C above 20-year average
Northern Hemisphere:
+0.22 C above 20-year average
Southern Hemisphere:
+0.11 C above 20-year average
(All temperature variations are based on a 20-year average (1979-1998) for
the month reported.)
As part of an ongoing joint project between The University of Alabama in
Huntsville, NOAA and NASA, Dr. John Christy, director of the Earth System
Science Center (ESSC) at The University of Alabama in Huntsville, and Dr.
Roy Spencer, a principal research scientist in the ESSC, use data gathered
by 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 for which 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 Spencer nor Christy 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
state and federal grants or contracts.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
