The SeaWiFS instrument aboard the Seastar satellite has been collecting ocean data
since 1997. By monitoring the color of reflected light via satellite,
scientists can determine how successfully plant life is photosynthesizing.
An article from the Financial Post says that recent studies of biosphere imaging from the NASA SEAWIFS satellite indicate that the Earth’s biomass is booming: ‘The results surprised Steven Running of the University of Montana and Ramakrishna Nemani of NASA, scientists involved in analyzing the NASA satellite data. They found that over a period of almost two decades, the Earth as a whole became more bountiful by a whopping 6.2%. About 25% of the Earth’s vegetated landmass — almost 110 million square kilometers — enjoyed significant increases and only 7% showed significant declines. When the satellite data zooms in, it finds that each square meter of land, on average, now produces almost 500 grams of greenery per year.’
