Climate<o:p></o:p></p>

color:#333333'>The burning of fossil fuels -- notably coal, oil and gas -- has
accounted for about 80 percent of the rise of atmospheric carbon dioxide since
the pre-industrial era. Now, NASA researchers have identified feasible emission
scenarios that could keep carbon dioxide below levels that some scientists have
called dangerous for climate.<br>
<br>
When and how global oil production will peak has been debated, making it
difficult to anticipate emissions from the burning of fuel and to precisely
estimate its impact on climate. To better understand how emissions might change
in the future, Pushker Kharecha and James Hansen of NASA's Goddard Institute
for Space Studies in New York considered a wide range of fossil fuel
consumption scenarios. The research, published Aug. 5 in the American
Geophysical Union's Global Biogeochemical Cycles, shows that the rise in carbon
dioxide from burning fossil fuels can be kept below harmful levels as long as
emissions from coal are phased out globally within the next few decades.<br>
<br>
"This is the first paper in the scientific literature that explicitly
melds the two vital issues of global peak oil production and human-induced
climate change," Kharecha said. "We're illustrating the types of
action needed to get to target carbon dioxide levels."</span><span
