Seasonal dead zones are annually occurring, typically in warm months of summer and autumn. Diel cycling hypoxia is a specific seasonal dead zone that only becomes hypoxic during the night; The type of dead zone can, in some ways, be categorized by the time required for the water to return to full health.
While oxygen minimum zones (OMZs) occur naturally, they can be exacerbated by human impacts like climate change and land-based pollution from agriculture and sewage. The prediction of current climate models and climate change scenarios is that substantial warming and loss of oxygen throughout the majority of the upper ocean will occur. [21]

Fish can't survive in the dead zones, and researchers. The Atlantic Ocean is teeming with life, but for the first time researchers have discovered dead zones in these waters - areas low in both ...
A dead zone is an area of water that cannot sustain aquatic life because the oxygen levels are low or depleted. The scientific term for a dead zone is called hypoxia, which in Latin means "too ...

A related phenomenon driven by climate change is woody plant encroachment, affecting up to 500 million hectares globally. [218] Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely ...
