WHAT IS CLIMATE CHANGE?

WHAT IS CLIMATE CHANGE AND IS IT VALID? IS IT MAN MADE OR IS IT JUST A NATURAL PHENOMENON? CAN IT BE REGULATED OR CONTROLLED?

WE SEE DROUGHTS IN CA, MASSIVE STORMS AND TORNADOES IN THE MID-WEST, LARGE HURRICANES IN THE GULF OF MEXICO AND TORRENTIAL RAINS IN THE EAST-COAST; BLIZZARDS, LARGE VOLCANIC ERUPTIONS AND EARTHQUAKES. DO WE AS HUMANS PLAY A ROLE IN THIS? WHAT DOES THE FUTURE HOLD FOR CLIMATE CHANGE HAVE UPON OUR WORLD?
