Yesterday the Providence Journal had an article on climate change. Here I quote a specific section regarding sea level changes:
“Because of changes in ocean currents, water temperatures and other factors, seas are rising faster in the Northeast than just about anywhere in the world. A recent study by the National Center for Atmospheric Research estimated that cities could experience more than double the global mean average for sea level rise over the next two decades.
From 1930, Sea levels in Rhode Island increased by about an inch a decade, until about 40 years age when the rate started to accelerate. The state has seen six inches of sea level rise since then.
The Rhode Island Coastal Resources Management Council has adopted projections by the national Oceanic and Atmospheric Administration to plan for up to 11.5 feet of sea level rise by the end of the century.“
I am wary of newspaper science, as the forum of front page journalism does not always lend itself to technical precision....and this one invaded my consciousness which started drooling out unchecked random thoughts:
It set me to thinking about global mass, CNAV concerns, regional pendulums, gravitational fields, and how sea levels could be predicted to rise at greatly different levels regionally. The simple minded part of me goes back to digging a large fish pond using a full hose from corner to corner to keep the sides level. My gut level, which is of course overly simplistic, says that if the mass of ocean water were already dispersed based on the mass and gravity of this third rock and our other gravitational impacts like moon and sun.....why would it unevenly change the height of sea level if you added more water? Isn’t ultimately all one connected big puddle that would relevel at the end...? OK... so I have no idea what I am talking about.......... but wouldn’t it re-disperse uniformly based on existing gravity...? Of course we do have all that melting ice...what of that......that’s relocating a substantial once solid mass while changing it to a liquid state.....
If the stated occurred, would we be correcting our relationship with a cosmos because our center of Mass was re-arranged and our.... oh heck..... “slosh factor” of liquid distribution changed? What of our “wobble”.......uh...rotational speed, precession, nutation, and regional perception of the vertical?
Are we going to have to correct our CNAV texts because earth is changing its distribution of mass and we’ll have lots more non uniformly distributed water sloshing about in funny places....or is it just too many decimal places right of zero.
My mind is running like the eight year old going why why why..... like why would all that water come to New England instead of south for a tropical vacation?.... lol...must have boat cabin fever...!
