The evidence is in: the gas we breathe is becoming scarcer

The seasonal variability of phytoplankton biomass in the Arabian Sea, though a well researched topic, its inter-annual variability is less explored and understood. Analysis of the satellite-derived chlorophyll pigment concentration in the Arabian Sea during 1997

Emissions of African dust increased sharply in the early 1970s, but the human contribution to land degradation and dust mobilization remains poorly understood. Now, a 3,200-year record of dust deposition off northwest Africa has been constructed.

Absorbing aerosols affect global-mean precipitation primarily in two ways. They give rise to stronger shortwave atmospheric heating, which acts to suppress precipitation. Depending on the top-of-the-atmosphere radiative flux change, they can also warm up the surface with a tendency to increase precipitation.

Satellite observations over the Arabian Sea revealed anomalous cooling in February 2008 associated with the anomalous north westerly winds from the continent. Land
