Det har længe stået klart, at øgede mængder af drivhusgasser i atmosfæren, fører til mindre iltindhold i oceanerne.
Men hvad bliver de fremtidige konsekvenser af større eller mindre områder i oceanerne med reduceret iltindhold til dyre og planteliv?


It is well‐known that O2 is fundamental for all aerobic life. However, the oxygen content of the ocean has been declining during the past few decades. This phenomenon, known as the "ocean deoxygenation," will have widespread consequences, which could eventually threaten the marine ecosystems. In this study, we systematically diagnosed the global oceanic oxygen budget on the basis of earth system models and found enhanced O2 escape from the ocean to atmosphere. The O2 outgassing is directly responsible for ongoing deoxygenation, and it will continue to increase in the future. A shift in the oceanic oxygen cycle characterized by increasing oxygen escape has been occurring as a consequence of human‐induced climate change, followed by intensified ocean deoxygenation and resulting in severe damage to marine biota.

@Peter Villadsen

Tak for dit indlæg.

Ser du en jævn kurve for dig i prognosen, eller kan der være tale om endnu et tippingpoint..?
