Global Temperature Report - May 2008

11.06.2008
Global average temperatures and temperatures in the tropics continued to fall in May, driven by a La Nina Pacific Ocean cooling event. Monthly global temperature report shows the Tropics recorded the fifth coolest month; while the Earth is the coolest in eight years.
May headlines:
Tropics see 5th coolest month;
Globe coolest since Jan. 2000
Global trend since Nov. 16, 1978: +0.13 C per decade
May temperatures (preliminary)
Global composite temp.: - 0.18 C (about 0.32 degrees Fahrenheit) below
20-year average for May.
Northern Hemisphere: - 0.05 C (about 0.09 degrees Fahrenheit) below 20-year
average for May.
Southern Hemisphere: - 0.31 C (about 0.56 degrees Fahrenheit) below 20-year
average for May.
April temperatures (revised):
Global Composite: + 0.02 C above 20-year average
Northern Hemisphere: + 0.17 C above 20-year average
Southern Hemisphere: - 0.14 C below 20-year average
(All temperature variations are based on a 20-year average (1979-1998) for
the month reported.)
Notes on data released June 4, 2008:
Global average temperatures and temperatures in the tropics continued to
fall in May, driven by a La Nina Pacific Ocean cooling event.
Compared to seasonal norms, temperatures in the tropical third of the globe
nearly tied for the fourth coolest month in 29 years, while the globe was
cooler than at any time since January 2000, according to Dr. John Christy,
director of the Earth System Science Center at The University of Alabama in
Huntsville.
A broad band of cooler than normal air virtually girdled the globe in May.
The tropics were 0.58 C (about 1.04 degrees Fahrenheit) cooler than seasonal
norms in May.
Coolest months in the tropics:
March 1989 - 0.73 C (-1.31 F)
February 1989 - 0.63 C (-1.13 F)
December 1988 - 0.62 C (-1.12 F)
July 1985 - 0.583 C (-1.05 F)
May 2008 - 0.579 C (-1.04 F)
As part of an ongoing joint project between UAHuntsville, 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 receive 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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
