Global Cooling was the "problem" in the 70's. Global Warming was the initial name for the "problem" 5 years ago.
So then, we have too many winters where it's unusually cold, so to save face all of the major proponents of the global warming "problem" decide that the "problem" should instead be called climate change.
Guess what, every year, we go through 4 different climate changes. Winter to spring, spring to summer, summer to fall, and fall to winter. Sometimes the summer is cooler or hotter than "normal" and sometimes the winter is colder or warmer than "normal." The problem is, whenever you ask a "scientist" to define "normal" they get all flustered and start pointing towards average temperatures, even though those "average" temperatures include lots of extremes over the last century-ish.
I will only get worried in the event that the "problem" is now called climate unchange. Unless it decides to hover around 75° all year, then I might not be so concerned. But if the thermometer doesn't move all year from either 120° or 20°, then I'll concede that there's a problem.
