Global Temperature Report - December 2008

16.01.2009
With a global average temperature that was 0.05 C warmer than seasonal norms, 2008 goes into the books as the coolest year since 2000.

Global temperatures during 2008 were influenced by a La Nina Pacific Ocean cooling event.

Global trend since Nov. 16, 1978: +0.13 C per decade

December temperatures (preliminary)

Global composite temp.: +0.18 C (about 0.32 degrees Fahrenheit) above
20-year average for December.
Northern Hemisphere: +0.41 C (about 0.74 degrees Fahrenheit) above 20-year
average for December.
Southern Hemisphere: -0.05 C (about 0.09 degrees Fahrenheit) below 20-year
average for December.
November temperatures (revised):
Global Composite: +0.25 C above 20-year average
Northern Hemisphere: +0.34 C above 20-year average
Southern Hemisphere: +0.16 C above 20-year average
(All temperature variations are based on a 20-year average (1979-1998) for
the month reported.)
Notes on data released Jan. 12, 2009:
The eleventh warmest global December in 31 years was also the fifth warmest
in the Northern Hemisphere, according to Dr. John Christy, a professor of
atmospheric science and director of the Earth System Science Center (ESSC)
at The University of Alabama in Huntsville. At the same time, the Southern
Hemisphere saw its tenth coolest of the past 31 Decembers.
WARMEST DECEMBERS, NH
2003 +0.62 C
2006 +0.54 C
1987 +0.52 C
1998 +0.42 C
2008 +0.41 C
2005 +0.40 C
Since November 1978, the Northern Hemisphere atmosphere has warmed more than
three times as fast as the Southern Hemisphere atmosphere (+0.19 C to +0.06
C per decade).
With a global average temperature that was 0.05 C warmer than seasonal
norms, 2008 goes into the books as the coolest year since 2000. Global
temperatures during 2008 were influenced by a La Nina Pacific Ocean cooling
event.
Another La Nina appears to be forming in the Pacific, which could chill
temperatures through 2009.

The processed temperature data is available on-line at:
vortex.nsstc.uah.edu/data/msu/t2lt/uahncdc.lt
As part of an ongoing joint project between The University of Alabama in
Huntsville, NOAA and NASA, Christy 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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
