ocean salinity patterns for the past 50 years reveal an intensification of [P - E] patterns as predicted by models, but at an even faster rate.

«These
patterns that are based on decadal analysis of modern data, and then the hydroclimate proxies that give the
salinity in the
oceans and the rainfall on land seem to show the same picture.»
By next year, the Argo project will have installed 3,000 floating sensors across all the
oceans, offering a daily snapshot of global
patterns of water temperature and
salinity — crucial for predicting the nature and pace of climate change.
My research indicates that the Siberian peat moss, Arctic tundra, and methal hydrates (frozen methane at the bottom of the
ocean) all have an excellent chance of melting and releasing their stored co2.Recent methane concentration figures also hit the news last week, and methane has increased after a long time being steady.The forests of north america are drying out and are very susceptible to massive insect infestations and wildfires, and the massive die offs - 25 % of total forests, have begun.And, the most recent stories on the Amazon forecast that with the change in rainfall
patterns one third of the Amazon will dry and turn to grassland, thereby creating a domino cascade effect for the rest of the Amazon.With co2 levels risng faster now that the
oceans have reached carrying capacity, the
oceans having become also more acidic, and the looming threat of a North Atlanic current shutdown (note the recent terrible news on
salinity upwelling levels off Greenland,) and the change in cold water upwellings, leading to far less biomass for the fish to feed upon, all lead to the conclusion we may not have to worry about NASA completing its inventory of near earth objects greater than 140 meters across by 2026 (Recent Benjamin Dean astronomy lecture here in San Francisco).
A typical oceanographic mooring, like one deployed in the northwest Atlantic
Ocean by the Global Ocean Ecoystems Dynamics (GLOBEC) program, holds a large array of instrumentation: seven current meters, seven temperature gauges, three optical turbidity scanners, four salinity / conductivity / pressure meters, and one Acoustic Doppler Current Profiler (ADCP) that records surface ocean current patterns around the moo

The
patterns of
salinity change can be used to infer changes in the Earth's hydrological cycle over the
oceans (Wong et al., 1999; Curry et al., 2003) and are an important complement to atmospheric measurements.
There is so little understanding about how the
ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming
patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming
patterns are co-located with increased evaporation and increased
salinity, and 3) shifting favored deep water formation locations as a result of a) shifted
patterns of enhanced warming, b) shifted
patterns of enhanced
salinity and c) shifted
patterns of circulation which transport these enhanced
ocean features to critically altered destinations.
In addition to the shallow La Niña — like
patterns in the Pacific that were the previous focus, we found that the slowdown is mainly caused by heat transported to deeper layers in the Atlantic and the Southern
oceans, initiated by a recurrent
salinity anomaly in the subpolar North Atlantic.
We can opine about changes in sea level,
salinity,
ocean currents, weather
patterns, etc..
The issue is that differences in mineral content,
salinity, density, and temperature all affect how the
ocean reacts to, and drives, changes in weather
patterns, climate variations over years or decades,
ocean current circulation, etc..
The observed changes in
salinity are of global scale, with similar
patterns in different
ocean basins (Figure 5.6).
Yes, afforestation of deserts (if it could be done) would increase the local temperatures and increase freshwater flow and thus reduce the
salinity of the
oceans and change circulation
patterns.
Documented long - term climate changes include changes in Arctic temperatures and ice, widespread changes in precipitation amounts,
ocean salinity, wind
patterns and extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones.
The report tracks
patterns, changes, and trends of the global climate system, including: greenhouse gases; temperatures throughout the atmosphere,
ocean, and land; cloud cover; sea level;
ocean salinity; sea ice extent; and snow cover.
Anthropogenic influences have contributed to observed increases in atmospheric moisture content in the atmosphere (medium confidence), to global - scale changes in precipitation
patterns over land (medium confidence), to intensification of heavy precipitation over land regions where data are sufficient (medium confidence), and to changes in surface and subsurface
ocean salinity (very likely).
Satellite - detected distribution and magnitude of the
salinity and bottom pressure in parts of the polar
ocean suggest a shift from a clockwise to a counterclockwise
pattern prevalent prior to the 1990s.
