Science can tell us a lot about the physical systems (such as the Global Climate System) that can,
and often does, have long term impacts on our day to day lives.
Of course we actually have to stop to observe what Science is saying. Take the time of learn what the lessons the Science and Scientists are trying to "convey" ... assuming we have human minds for a reason, of course ...
The Great Ocean Conveyer Belt
Environmental Literacy Council
Thermohaline circulation is driven by changes in the density of sea water. The conveyor belt transfers warm water from the Pacific Ocean to the Atlantic as a shallow current and returns cold water from the Atlantic to the Pacific as a deep current that flows further south. [...] By the time it heads up the Atlantic it turns into the Gulf Stream. As it passes Europe, the surface water evaporates and the ocean water cools, releasing heat to the atmosphere. This release of heat is largely responsible for the relatively warm temperatures enjoyed by Western Europe. As the water becomes colder, it increases in salinity and becomes dense, sinking thousands of meters below the surface. [...]
The ocean conveyor belt plays a crucial role in helping to shape the Earth's climate. However, global climate changes could alter, or even halt, the current as we know it today. [...]
Great ocean conveyor belt
UNEP/GRID-Arendal -- Environmental Knowledge for Change
[...] The two counteracting forcings operating in the North Atlantic control the conveyor belt circulation: (1) the thermal forcing (high-latitude cooling and the low-latitude heating) which drives a polar southward flow; and (2) haline forcing (net high-latitude freshwater gain and low-latitude evaporation) which moves in the opposite direction. In today's Atlantic the thermal forcing dominates, hence, the flow of upper current from south to north.
When the strength of the haline forcing increases due to excess precipitation, runoff, or ice melt the conveyor belt will weaken or even shut down. [...]

This colorful activity is a favorite of my students. It is an effective way to show students how salinity and temperature affect the density of water, an important concept in understanding ocean currents.
This little-noticed global form of temperature "conveyance" matters, or should matter, especially on this historic anniversary ...
when in the course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature [...] a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
And those
"impellers" are many ... that's assuming the "Laws of Nature" deserve an
"equal station" to the opinions of those who
would deny those same Laws ...
US East Coast a "hot spot" for sea level rise -- Study
Changes in Atlantic "conveyor belt" current have an impact
by Deborah Zabarenko, (Reuters) WASHINGTON , June 25, 2012
[...]
Researchers found that sea levels in this corridor were rising between three and four times faster than the global average, and they fit with computer simulations aimed at predicting the effects of climate change.
One reason for the accelerated rise in the Atlantic Ocean along the East Coast is an apparent slowdown in the Atlantic Meridional Overturning Circulation, a massive current sometimes called the "conveyor belt," study author Asbury Sallenger Jr. said by telephone from St. Petersburg, Florida.
The melting of glaciers, which are made of compacted snow, sends fresh water into the salty Atlantic and into this current, Sallenger said.
"It turns out that this leads to a slowdown across the whole system ... including the currents that run along the coast of the United States," he said. "And there are ways by slowing down those currents, you change the level of the sea against the coastline."

This is not Rocket Science afterall ...
"It's just Physics." You know the 'same stuff' that keeps planes in the air, cars on the road, and food in frig.
You know that "system of knowledge covering general truths ... as obtained and tested through 'repeatable' methods." Sci·ence -- a simple noun. A human method of Learning.
You know "it's just Science." The discovery of the Laws of Nature; from the cosmic backdrop in which we live.
Who knows what we could learn if we actually took the time to respect those "Laws", to adhere to them. And actually invested the resources into Science, as if it matters. Because you know, it kind of does.
... especially within that historic "course of human events" ... where that "human current" still meanders, is still trying finding its way through the "forcings" of chaos and disorder, which would otherwise grind to a halt, our slow steady progress ... towards ever greater discovery of the world, in which we live ...
