The Blob (Pacific Ocean) the surface waters of the mid-latitude Pacific Ocean flipping from a cold phase to a warm phase in a cycle known as the Pacific decadal oscillation (PDO). This poorly-understood change happens at irregular intervals of years or decades. During a warm phase, the west Pacific becomes cooler and part of the eastern ocean warms; during the cool phase, these changes reverse. Scientists believe a cold phase started in the late 1990s and the arrival of the Blob may be the start of the next warm phase. The PDO phases may also be related to the likelihood of El Nino events.
World Ocean Conference and coastal resources, physical alteration, poor land-use planning, and socio-economic pressures, equally concerned over marine ecosystems and living resources being affected by sea level rise, increased water temperature, ocean acidification, changing weather patterns, and other variations that may result from climate change, and how these alterations may aggravate the existing pressures of marine environmental degradation and increase risks to global food security, economic prosperity, and the well-being of human populations. Realizing the detrimental effects and importance of climate change, The WOC agreed to discuss the commitments on how to increase the role ocean in reducing the impact of climate change.
