Such as wildfire feedback, coastal erosion, weather / atmospheric anomalies, seasonal changes, species adaptation, ocean currents etc..

Using an ocean circulation model for the shelf, the authors find that surface temperatures may increase by 0.5 to 2.0 °C, seasonal surface salinity may drop by up to 2 PSS in some areas, and that Haida Eddies will strengthen, as will the Vancouver Island Coastal Current and freshwater discharges into coastal waters.

Extension of the current synoptic capacity of 6 - 7 days to 14 days would be a great start, but the lack of sufficient weather in the oceans would make this difficult to achieve for vulnerable coastal communities.

This policy document aims to provide context for Rio +20 discussions through analysis of current challenges in ocean and coastal management around the world, assessment of how well the multiple goals and objectives of previous international efforts have been met, and building on recent dialogue and inputs including the meeting of the UN Informal Consultative Process on Oceans and the Law of the Sea (UNICPOLOS) and the Secretary General's report on Oceans and Law of the Sea.

(Sec. 479) Requires each state to prepare a natural resources adaptation plan detailing the state's current and projected efforts to address the potential impacts of climate change and ocean acidification on natural resources and coastal areas in order to be eligible for funds under this subpart.

This study shows that a weaker surface ocean current system produces colder coastal SST's along the Atlantic coast of Florida, thereby reducing the length and the total seasonal accumulation of rainfall in the wet season of Peninsular Florida relative to the simulation in which these currents are stronger.

The results also highlight coastal regions that are well - represented in current generation climate models (and those that are not) and the time periods over which coastal sea level may be used as a proxy for the large - scale ocean circulation.

-- In order to be eligible for funds under section 480, not later than 1 year after the development of a Natural Resources Climate Change Adaptation Strategy required under section 476 each State shall prepare a State natural resources adaptation plan detailing the State's current and projected efforts to address the potential impacts of climate change and ocean acidification on natural resources and coastal areas within the State's jurisdiction.

The complicated currents within the ocean slosh the growing heat around, in 2D (ENSO, PDO, NAO, AO, AAO) and 3D (thermohaline conveyor belt, coastal upwellings, ocean terrain dependent vertical currents, etc).

Nevertheless, if El Niño comes on as strong as current projections seem to indicate, we can say with some level of confidence that coastal South American countries will see above average rainfall and flooding in the coming months, while countries on the other side of the ocean like Australia and Indonesia will likely see drought.

In Washington and Oregon, oysters farms are in coastal Pacific waters where upwelling currents are bringing up cold, deep water with higher amounts of CO2 and a more acidic pH. Watch and listen to two oyster farmers from Taylor Shellfish Farms in Washington state talk how about ocean acidification is impacting their young oysters.

Tide heights near ice shelves can be measured using traditional coastal tide gauges and bottom pressure recorders, while currents can be measured with meters on moorings in the open ocean or deployed through boreholes drilled through ice shelves, which are the floating portions of ice sheets.

Lansner and Pepke Pedersen (2018) point out that, due to the divergent rates of warming and cooling for land vs. ocean water, there is a significant difference in the range of temperature for the regions of the world influenced by their close proximity to oceans and coastal wind currents (ocean air affected, or OAA) and the inland regions of the world that are unaffected by ocean air effects and coastal wind because they are sheltered by hills and mountains or located in valleys (ocean air sheltered, or OAS).

Whether it's the threat of dramatic sea level rise to coastal areas or current climate change refugees from low - lying islands, the effects of climate change and global warming on the world's oceans are both real and imminent.
