Artificial upwelling
Artificial upwelling is a proposed marine geoengineering technique that pumps nutrient-rich deep water to the sunlit surface to boost phytoplankton growth and, in principle, sequester CO2.
Atlantification of the Arctic
Atlantification of the Arctic is the growing influence of warm, salty Atlantic Water in the Arctic Ocean, which warms the region and reduces its sea ice.

Attribution analysis in climate science is a statistical method that quantifies how much human activities and natural factors each contribute to observed climate changes and extreme events.
Attribution of recent climate change
Attribution of recent climate change, also called man-made global warming attribution, is the science of measuring how much observed warming is caused by human activities.
