Carbon map launched
As Nasa launched a satellite into orbit to monitor carbon dioxide emissions, an interactive Google Earth map showing emissions from across the US was unveiled.
The project, led by Purdue University and dubbed Vulcan, uses colours to reveal the intensity of carbon emissions in an area.
It also breaks down the emissions into different sectors, revealing in metric tonnes how much commercial, residential, aircraft, transport and electricity generation emits in each area.
"This will bring emissions information into everyone's living room as a recognisable, accessible online experience," said Kevin Gurney, the project leader.
He added: "What was once the realm of scientists will now be provided directly to the public. We hope to eventually turn it into an interactive space where the public will feed information into the system to create an even finer picture of emissions down to the street and individual building level."
Meanwhile, Nasa's Orbiting Carbon Observatory satellite went into space to monitor carbon dioxide in the earth's atmosphere.
It will take eight million measurements every 16 days for two years.http://www.purdue.edu/eas/carbon/vulcan/GEarth/
