Those that worry about global warming can not accept nature is in charge and there is nothing humans can do to stop nature. As reported in this Huffington Post article:
Global warming is revving up the planet’s cycle of evaporation and precipitation, making wet places even wetter and dry places drier, a new study suggests.
A team of researchers found the intensity of the water cycle increased roughly 4 percent over the last half of the 20th century by examining changes in the ocean’s salt content.
This means more movement of water between the locations where it’s stored, such as the atmosphere, oceans and lakes. Their results indicate that as a result, salty places are becoming saltier due to more evaporation, while fresh places are becoming fresher due to more precipitation.
This article is reporting on research done by Paul Durack, a postdoctoral researcher at the esteemed Lawrence Livermore National Laboratory. The research has found that the salt content of the oceans has increased over the last hundred years.
I wonder how much money was spent on this research? Because any 18 year old that passed high school chemistry could have predicted the results in advance for no cost.
For those that have never studied earth sciences, allow me to explain. When the earth cooled and the oceans eventually formed the oceans were effectively fresh water. Over the millions of years as water evaporated from the oceans, all of that evaporated water eventually condensed as rain and some of rain invariably fell on land masses. Rain water runoff dissolves some soluable minerals (salts) from the earths surface and are eventually carried back to the oceans through rivers and streams. When water evaporates, the dissolved minerals in the water do not evaporate. They stay behind. If you take any source of water that has not been purified and put in a pot and boil it dry, you will find a whitish scum on the bottom of the pot. That is mineral salt. So, over time, the concentrations of these dissolved minerals increase and that is why the oceans eventually became salt water.
Guess what? This process is going to keep happening because the laws of nature say so. The salinity of the oceans will keep increasing until one of two things happen: until there are no more soluble minerals on the surface of the earth’s land masses or the oceans become saturated. Every mineral has a natural limit to its solubility. Beyond that point if more soluble mineral enters the system it will precipitate as a solid and fall to the bottom.
But doesn’t that mean that eventually the oceans won’t be able to sustain sea life? Yes it does. Unless man finds a way to change the laws of nature, the salt concentration of the oceans will continue to increase. Me, I’m not going to lose any sleep over it.
Well, that’s what I’m thinking. What are your thoughts?
