Other groups that study climate change also rank these years as among the warmest, though the exact rankings vary depending upon details of the analyses. Results differ especially in regions of sparse measurements, where scientists use alternative methods of estimating temperature change.
Goddard Institute researchers used temperature data from weather stations on land, satellite measurements of sea surface temperature since 1982 and data from ships for earlier years.
“2007 is likely to be warmer than 2006,” said James Hansen, director of NASA GISS, “and it may turn out to be the warmest year in the period of instrumental measurements. Increased warmth is likely this year because an El Nino is underway in the tropical Pacific Ocean and because of continuing increases in human-made greenhouse gases.”
Most places on the globe have warmed in recent decades, with the greatest warming at high latitudes in the Arctic Ocean, Alaska, Siberia and the Antarctic Peninsula. Most ocean areas have warmed. Climatologists say that warming is not due to local effects of heat pollution in urban areas, a point demonstrated by warming in remote areas far from major cities.
In their analysis for the 2005 calendar year, GISS climatologists noted the highest global annual average surface temperature in more than a century.

High-precision measurement of the g-factor eleven times more precise than before / Results indicate a strong similarity between protons and antiprotons
The magnetic moment of an individual proton is inconceivably small, but can still be quantified. The basis for undertaking this measurement was laid over ten...

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
