Degraded Tropical Forests Now Release More Carbon Than They Store, New Study Finds

Tropical forests may no longer be acting as carbon sinks and could be releasing more carbon than they store, according to troubling new research.

A study published Thursday in the journal Science finds that forests across Asia, Latin America and Africa release 425 metric tons of carbon per year, which is equivalent to nearly one-tenth of the U.S.' annual carbon footprint.


Researchers found nearly 70 percent of this loss is caused by small-scale degradation, the result of selective logging, drought and wildfire. All is not lost for forests, however. Researchers say that policies to curb deforestation, reduce degradation and restore land could turn forests back into carbon sinks.

"These findings provide the world with a wakeup call on forests," the study's lead author, Alessandro Baccini, a scientist with the U.S.-based Woods Hole Research Center, said in a statement.

"If we're to keep global temperatures from rising to dangerous levels, we need to drastically reduce emissions and greatly increase forests' ability to absorb and store carbon."

South Africa is home to around 1,300 of the world's roughly 7,100 remaining cheetahs. It's also the only country in the world with significant cheetah population growth, thanks largely to a nongovernmental conservation project that depends on careful and intensive human management of small, fenced-in cheetah populations. Because most of the reserves are privately funded and properly fenced, the animals benefit from higher levels of security than in the increasingly thinly funded state reserves.

Scientists are on the brink of scaling up an enzyme that devours plastic. In the latest breakthrough, the enzyme degraded plastic bottles six times faster than previous research achieved, as The Guardian reported.
