Ocean greenery under warming stress
A century of phytoplankton decline suggests that ocean ecosystems are in
peril.

"The research reveals an unsettling centennial downwards trend,
superimposed on shorter-term variability. The scientists found that the
average global phytoplankton concentration in the upper ocean currently
declines by around 1% per year. Since 1950 alone, algal biomass
decreased by around 40%, probably in response to ocean warming � and the
decline has gathered pace in recent years".

"Clearly, 40% is a huge number," says Paul Falkowski, an oceanographer
at Rutgers University in New Brunswick, New Jersey. "This implies that
the entire ocean system is out of steady state, slowing down."
