I too believe in climate change--absolutely.  I believe in global warming--and in global cooling--and in global “just the same.”  By definition “climate” changes every day, even every hour--just look at your daily weather forecast.  On a larger scale, climate has changed repeatedly over millennium; ice ages have come and passed.  Fifty years ago prognosticators mulled over a coming ice age (which didn’t). Climate will change again--over decades, centuries, and longer, given a wide variety of conditions, e.g., the sun is a variable star.  And the climate may, repeat may, be changing over a period of time so that the Earth becomes measurably warmer.  But living long enough to prove/disprove it is problematic.
