According to a new study, the increase in global temperatures may play a significant role in altering the capacity trees have to store carbon dioxide, by changing the forest nitrogen cycle.
“Runoff from agricultural and urban watersheds has increased the availability of nitrogen in streams and rivers, greatly increasing nitrous oxide production rates,” said Jake Beaulieu, a postdoctoral researcher at the … [Read full article]
It seems we always take the most basic things for granted. With regards to adequate water, air, and soil (things we assume will always be there) we are gradually becoming … [Read full article]
According to the theory, an increase in atmospheric CO2 (the main GHG responsible for global warming) will have an enhancing effect on forest growth, since plants and trees require CO2 … [Read full article]
An international team of climate and ocean scientists, led by Wei-Jun Cai (U of Georgia, Athens), predicts that the “Arctic Ocean basin will not become a large atmospheric CO2 sink under ice-free conditions.” Using data from a 2008 high-resolution survey of the entire Canada Basin, the team explains the complex “air-sea flux” and other reasons why sea-surface CO2 continues to increase.
Scientists have concluded that forests with excessive nitrogen concentrations reduce the amount of carbon dioxide released into the atmosphere. During a ten year study in Michigan by the National Science … [Read full article]
