LANSING, Mich. —After more than a decade of research, a team of scientists has found that by releasing one pollutant into the environment, we might help capture another.
Findings from one of the National Science Foundation's longest-running studies show that adding nitrogen to soil prompts northern hardwood forests to absorb more heat-trapping carbon dioxide. As the atmosphere's most abundant element, nitrogen plays a significant role in ecosystems, and one to which scientists and policymakers are paying greater attention. Growing evidence suggests that as humanity pumps more nitrogen into the environment, forests could become bigger carbon sinks and help mitigate climate change. But experts warn that it's a dangerous experiment that could have serious consequences. Nitrogen comes from a vast array of sources: farm fertilizer, car exhaust, factory and power plant emissions.
There scientists found that decomposition of twigs and other tree litter slowed. There are major caveats, however. Physical Sciences Division.

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Scientific evidence for warming of the climate system is unequivocal. The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1 Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale.
