Satellite data has only been available since 1976, but became a major impact in mid 80's.
In order to use Satellite Data, scientists must first have a basis and reliable instruments.
One of my favorite Satellite Data info is from the
University of Miami. [ Full data page here]
Ocean Heat Content.
Heat
can not be measured.
But yet here we have, in graphical format, the
Heat Content of the Atlantic Region.
And they can show the
Depth of Water Heat content at 2 different reference temperatures 20° and 26°C
This is their Error of analysis.
What are the Streaks? The combined orbital paths of 3 Satellites.
Useful? Yes
Predictive? Yes , but how far in the future?
Historical Trends? So so.
___________
Level of the Oceans...
Perhaps by Satellites, but I am very doubtful of Accuracy. Time will tell.
Since the Earth Water Content is very slowly lost to outer Space, we can assume is it a Constant mass of H2O.
It is the form of Water [Solid, Liquid, Vapor] that is the Key to Ocean Levels.
And Yes, we have Satellites monitoring both Polar Regions Ice changes. This is the Biggest Factor on Levels.
_________
Global Climate, Climate Change, or Weather...
We are somewhat lucky that many of the people of the world can actually change their local climate.
If you don't like Ice or Cold
relocate toward the Equator.
If I don't like Hurricanes, Move away from the Coast.
For those who can not relocate, Adapt!
______
The major control of North American Climate is ...
Pacific Ocean and its Currents.
The Atlantic and Gulf are a minor second place.
I leave it to other to infer what affects the Pacific Ocean.
Hint: It is a Big Yellow Object in sky, daily.

PS: The best weather forecast is 5 Days. Longer times of up to 16 days are a good guess. Trying longer is Done By NOAA.
PSS: My next 10 year forecast. Warm Summers and Cool Winters,
