Sentences with phrase «release significant amounts of carbon»

If Arctic areas continue to warm, scientists speculate that thawing Arctic soils may release significant amounts of carbon dioxide and methane currently trapped in permafrost.
With thawing permafrost projected to release significant amounts of carbon in response to climate change, one of the editors of JGR: Biogeosciences reflects on the slew of recent papers in this field.
A more sound approach would recognize that (1) converting old forest to young forests releases significant amounts of carbon (both above and below ground), (2) young forests are only good carbon sinks if they are allowed to grow and hold onto the carbon for centuries, yet there are too few economic incentives for doing so, and (2) the fraction of carbon that is put into long - term storage after logging is very small, i.e. old forests are better at storing carbon than our disposable culture.

Not exact matches

With Arctic temperatures warming twice as fast as the global average, scientists estimate thawing permafrost could release large amounts of carbon into the atmosphere through the end of the century with significant climate impacts.
Plants naturally absorb carbon dioxide and release oxygen, but certain plants also eliminate significant amounts of benzene, formaldehyde and / or trichloroethylene.
According to a new study of 28,000 measurements collected between 2000 and 2006 and analyzed by NOAA's CarbonTracker system, only about a third of the carbon dioxide is absorbed by carbon sinks such as the soil and forests; a large portion of it ends up in the atmosphere - but that still leaves a significant amount unaccounted for.Interestingly, the CarbonTracker found carbon emissions to be highest in the Midwest; that single region released more carbon dioxide than any other country - except Russia, China, India and, of course, the U.S. Carbon dioxide was found to be most readily absorbed east of the Rocky Mountains and in northern Canada.
Recent model results, by contrast, suggest that significant impacts will persist for hundreds of thousands of years after emissions cease;» Matthews and Caldeira (2008): «We show first that a single pulse of carbon released into the atmosphere increases globally averaged surface temperature by an amount that remains approximately constant for several centuries, even in the absence of additional emissions.»
