Der menschliche Einfluss auf den Ozean wird sich bis 2050 verdoppeln: Die Tropen und die Polen werden die schnellsten Auswirkungen verändert, und die Küstengebiete werden die Hauptlast der erhöhten Auswirkungen spüren

> “Our cumulative impact on the oceans, which is already substantial, is going to double by 2050 — in just 25 years,” said marine ecologist and NCEAS director Ben Halpern, who led the effort to forecast the future state of marine environments as they bow under the combined pressures of human activities, which include ocean warming, fisheries biomass loss, sea level rise, acidification and nutrient pollution, among other impacts. “It’s sobering. And it’s unexpected, not because impacts will be increasing — that is not surprising — but because they will be increasing so much, so fast.”
>Their quest to build a comprehensive model of human impacts on the ocean led to a 2008 paper in the journal Science, a landmark study that synthesized 17 global data sets to map the intensity and extent of human activity on the world’s oceans. That initial view revealed startling results: No place was untouched, and 41% of the world’s marine environments were heavily impacted.

>“The previous paper tells us where we are; the current paper tells us where we are headed,” Halpern said.

Serious issues, dealt with in relatively fatuous ways. It’s simply not possible to attach a consistent scale of seriousness of impacts of different types without making value judgements as to what is more important, whether for the oceans themselves or for the people who rely on them.
