A look at weather extremes and the big-picture climate connections.

Science Made Simple: Take the Dog for a Walk

Oftentimes scientists and journalists make the simplest of scientific concepts sound incredibly complicated. Take the difference between climate and weather, for example. The old adage is that "climate is what you expect, weather is what you get," since day-to-day weather may depart significantly from average conditions. But that doesn't really tell you much about how climate is measured over the long-term, or when weather ends and climate begins. The explanation I like best comes from the comedian Stephen Colbert, when, during a segment with Climate Central's Heidi Cullen, he said: "Is not climate just made up of thousands of little weathers?"

Or consider this delightfully clear cartoon posted on Youtube that uses a unique analogy — a man walking his dog — to describe the differences between weather and climate. It's simple, to the point, and best of all, adorable. Check it out.

Where *exactly* does weather “end” and climate “begin”?  And what if the doggie’s deviations are increasingly large, frequent, and more in a particular direction?

Good questions, Stu. I think a global warming cartoon would depict an increasingly meandering dog, with the owner struggling to keep up smile

Stu, et al,

Weather is what happens to the atmosphere in the short term, while climate is essentially weather averaged over a longer time span - typically 30 years or so.  We can have record freezing temperatures on a particular day without that event’s having anything to do with the longer-term climatic trend known as global warming.

Great explanation… I’ll be sharing. 

And great point, Stu. 

Andrew, what if the dog is pulling a sled… with 9 other dogs?

It’s actually simpler than that.

When it’s hot, it’s climate change. When it’s cold, it’s weather.

drjohn, that is what an overzealous climate change campaigner might say. An overzealous climate change denier might say the opposite. A climate scientist statistically analyses the data and comes up with the same result as everyone else who statistically analyses the data… The climate is warming.

THANK YOU!  This is great and I’ll share it widely because non-science people DO get confused.

The dog is in the process of pulling us over a cliff.

John, the situation is more analogous, it would seem, to the case where even if energy taken in by the dog owner were to be reduced, stored energy would enablle him to continue up the hill until ‘equilibrium’ is reached.
