Earth's Rising Atmospheric Co2 Concentration: Impacts on the Biosphere

“…They concluded that "it seems likely that the increase mainly reflects enhanced metabolic activity of the land biota" and that "one obvious factor that might produce this enhancement is the CO 2 concentration itself." Nearly a decade later, Keeling (1994) observed that the amplitude of the seasonal CO 2 cycle had increased by an additional 20% at high latitudes in both hemispheres between 1988 and 1993, noting that "a preliminary investigation suggests that an increase in the net primary production of plants… caused the amplitude increase." Fourteen months after this revelation, Keeling et al (1995) reported that the amplitude of the seasonal CO 2 cycle at Mauna Loa had also risen significantly over this time period; while Okamoto et al (1995), after analyzing seasonal CO 2 amplitude trends at seventeen stations stretching from the South Pole to Alaska, concluded that "CO 2 fertilization exists on the global scale."…”

Erhaltung und nachhaltige Nutzung der Biosphäre

“…Eine Feinanalyse der Mauna-Loa-Daten (Keeling, 1994) enthüllt, daß die saisonalen "Inhalationen" und "Exhalationen" der Biosphäre mit dem langfristigen Anstieg des Kohlendioxids in der Atmosphäre immer ausgeprägter werden (Idso, 1995). Abb.…”
