I spent 1958 at Sonderstrom AB Greenland, while there we supported a French scientist who was studying the rate the polar ice cap was melting. Miles out on the ice cap holes were drilled, dynamite charges placed in them, and set off as seismograph equipment took readings. At that time, (50 years ago) it was predicted that a warming trend was taking place. In 1958 the southern tip of the polar ice cap was miles closer to Sonderstrom than it is today. Proof positive that a warming trend is causing the ice cap to melt. Proof of a warming trend is also evident from flying over the Arctic Sea and noting the deterioration of icebergs, and reduction in size of those still there.
My point, I can't determine the cause, but we have experienced a warming trend over the past few years. Many change have resulted, areas that formerly had an abundance of annual rain are now experiencing drought conditions. Exceptional temperature changes have take place all over the world. If it is not global warming, then what is causing the changes?
I think one of prudence judgment would consider "global warming", and "climate change" one and the same. Acres of concrete now stand where just a few years ago great forest grew. This is true in almost all parts of the world, Could this be the major contributing factor in the warming, and/or climate change?
