Why is it that Right Wingers always tend to be the least educated on such matters? Droopy's hilariously uninformed rants about PH having nothing to do with acidity, comes to mind.
First of all, my statements about PH were scientifically correct. The oceans are not becoming more acidic only a tiny bit less alkaline on one side of the PH scale. To do that, they would have to cross a threshold that the laws of physics and the nature of the oceans themselves will simply not allow.
I think it has everything to do with their paradigm of the world. They really do live in a microcosm of their own. If it is cold, right now, where they live, well global warming can't be true. And of course, you bring up science, they claim it is a Liberal conspiracy. There is no getting through to the FOX sheeple.
The idea of DAGW/CAGW was never more than a hypothesis, and never graduated to anything approximating a theory for two critical reasons, the first being a complete lack of observational, empirical evidence supporting the theory, and secondly because every major claim made by the theory as been thoroughly discredited by empirical scientific evidence across a number of earth science disciplines over the past twenty years.
Competent atmospheric scientists knew decades ago the the basic laws of physics underlying claims of human or naturally induced climate change as being based on atmospheric CO2 were dubious, and as we now know that the (as yet unvalidated) GCM's have been spectacularly wrong (unless one is programming and using them as curve-fitting tools) in all the projections they have made and claims made from them, and that nature has very simply not behaved at all as the models predicted, the game is long over.
But the computer models are not doing science, and the fad among "climate scientists" for using them in lieu of doing actual empirical field science is, and should have been, telling in and of itself.
Average sea level around the world has been rising for many years.
It sure has - for about 14,000 to 17,000 years, ever since the end of the last major glacial age and, more recently, since the end of a smaller ice age over 5,000 years ago and since the end of the LIA (the present modest warming trend - well within known natural variation - being itself a "rebound" from that climatic event).
Over the last 150 years, sea levels have risen at an average rate of six inches per century (up from two inches per century over the last 2,000 years) and there is no empirical evidence that it is accelerating.
Present sea level rise is projected, from empirical study (tide gauge data and satellite telemetry data) not computer models, to be approximately 4 to 6 inches over the course of the next century
