NASA releases global warming map

Posted on December 17, 2010 by Rashid Faridi

NASA has released a new analysis of temperature change.

2000-2009

 

2000-2009

1970-1979

1970-1979

The map shows temperature anomalies for 2000-2009 and 1970-1979 relative to a 1951-1980 baseline.
To conduct the analysis, NASA’s Goddard Institute for Space Studies (GISS) uses “publicly available data from 6,300 meteorological stations around the world; ship-based and satellite observations of sea surface temperature; and Antarctic research station measurements.”

Map information park in China

Posted on December 15, 2010 by Rashid Faridi

China has invested 15 billion yuan ($2.25 billion) to build the first national-level Geographic Information Industrial Park, which covers a total area of about 66.7 hectares.The venture will further develop the geographic information industry in the country, said government officials.
The park, which has garnered investment from the State Bureau of Surveying and Mapping and the Beijing municipal government, is scheduled to be operational by 2013. More than 100 companies in the geographic information industry will enter the park by then.

A Never-Before-Seen Signal from the Dark Epoch of the Universe

Posted on December 12, 2010 by Rashid Faridi

Bowman and Alan Rogers of Massachusetts Institute of Technology developed a small-scale radio astronomy experiment designed to detect a never-before-seen signal from the early universe during this period of time, a development that has the potential to revolutionize the understanding of how the first galaxies formed and evolved.

Thirteen billion years ago our universe was dark. There were neither stars nor galaxies; there was only hydrogen gas left over after the Big Bang. Eventually that mysterious time came to an end as the first stars ignited and their radiation transformed the nearby gas atoms into ions. This phase of the universe’s history is called the Epoch of Reionization (EoR), and it is intimately linked to many fundamental questions in cosmology. But looking back so far in time presents numerous observational challenges…

‘Greener’ Climate Prediction Shows Plants Slow Warming

Posted on December 10, 2010 by Rashid Faridi

A new NASA computer modeling effort has found that additional growth of plants and trees in a world with doubled atmospheric carbon dioxide levels would create a new negative feedback — a cooling effect — in the Earth’s climate system that could work to reduce future global warming.
