It is becoming more apparent that climate change on the earth is a cyclic phenomenon caused by among other things cyclic changes in the radiant output of the sun.
Also we will have to work a lot harder on our greenhouse gas output (maybe really big SUV's) to rival the earth's output of greenhouse gases (which dwarf's man's). Volcanoes are among the most grievous offenders. Someone needs to check their carbon credits! I think they've exceeded their allotment!
There are certain segments of society who have learned how to take advantage of, and make money from, the panic they can induce in masses worldwide. Look at the commercials you see on your Television. How many are aimed at scaring you into a behavior from which someone will benefit.
