Weather vs. ClimateRSS

I can't tell you how old you'll be when you die, but . . .

I can't tell you when you'll die, but I can tell you the average age of death of people your age. That's how life insurance companies they make money. That's the difference between weather and climate. Averages are predictable; individual events are not.
A warming planet doesn't get rid of winter

"People across the northern hemisphere are facing the fact that a warming planet doesn't get rid of winter ... now is a good time to remind ourselves that weather, like death and taxes, will always be with us." — Robert Henson, University Corporation for Atmospheric Research
You have to watch many waves before you can see the tide.

When you first arrive at the beach can you tell whether the tide is going in or out? No, not quickly: it would perhaps take you fifteen minutes of wave-watching before you could say for certain. And who's to say that a sudden big wave wasn't caused by a passing ship? It takes time to see the trend.

Now let's adopt the scientist's method for determining the tide. This time bring a g...
Weather = like a coin flip.  Climate = 1000 flips

Weather is like flipping a coin once. It is unpredictable. Climate is the average weather, measured over decades. It's like flipping a coin 1,000 times. The long term average is much more predictable.
Cold snap?   A dark night disproves lengthening days?

Does a winter cold snap disprove global warming? That's like saying in April, "Don't tell me the days are getting longer. Look how dark it is tonight!"

Wide short-term fluctuations can mask a slow, long-term trend. Global warming won't eliminate winter, any more than long summer days eliminate nighttime.
"...Like leaving the 'fridge door open."

As the Arctic warms, so the northern continents at higher latitudes experience cold winters with heavy snow falls. It's rather like the fridge door being left open: warm air goes in at the top as cold air falls out into the room.
Cold winter in Europe.   Did you check Siberia?

Cold winter in Europe, but warm in Siberia. So this disproves AGW? That's like saying: 'My keys were in my jacket, now they're not. That proves they're lost. (But have you checked your other coat? your pants?)
Temperature change is like walking the dog.

When CC walks his dog, he moves in a straight line, but his dog, TC, tugs on the leash and wanders right and left. TC is Temperature Change (short term variance) and his owner, CC, is Climate Change (long term trend). Of course, they both arrive at the same destination.
Weather vs. Climate:   'I lost 2 lbs last weekend..."'

Climate is about long term trends. Weather is short-term fluctuations.

Drawing conclusions about climate by looking at the weather is like saying 'I lost 2 lbs yesterday!' Every veteran weight-watcher knows that one day means nothing. It's the long term trend that counts.
M. Twain:  Climate is what you expect.   Weather is what you get.

Climate = what you expect. Weather = what you get. Variation: When travel, climate determines what you pack. Weather determines what you put on each morning.
Weather vs. climate...is like waves vs. tide.

Weather is short term and unpredictable, like ocean waves.

Climate is long-term and predictable, like the tides.
It's stopped warming?   Waves vs. tides.

Have you ever stood on a beach and watched the tide coming in? The long-term trend (the water level steadily rising) is hidden behind short-term variability (the size of waves washing up the beach).
Cold winter?   He won 2 hands of poker and thinks. . .

Saying a cold winter disproves long-term global warming is like the guy who wins two hands of poker and thinks he's figured out how to 'beat the house.' Time to double down on his bets, right?
Weather is like CNN.  Climate is like the History Channel.

Weather is like CNN. Climate is like The History Channel.
Mark Twain was wrong:   We actually are doing something.

Mark Twain famously said, "Everybody talks about the weather, but nobody does anything about it." It turns out that he was wrong. We have been doing something...but unintentionally and not for the better.
Even with A Fever, I can still dance!

Sound silly? So is saying, 'Because it is snowing today there cannot be global warming.'
Intense snowstorms!  Yep.  Actually that is global warming.

(With climate change) “we will see a shorter snow season, but more intense individual snowfall events. – Dr. Michael Mann, Climatologist at Penn State University
Weather is your mood and climate is your personality

"Weather is your mood and climate is your personality." — Dr. Marshall Shepherd, President of the American Meteorological Society
Weather you see from your window, climate you see from a satellite

‘Weather is what you see outside your window, climate is what you see from a satellite.’ – Scott Mandia, Professor of Physical Sciences at Suffolk County Community College, New York.
Climate is the canvas and weather is what is painted on it

“Climate is the canvas and weather is what is painted on it. Humans have changed the climate so now all weather is affected by us.” – Scott Mandia, Professor of Physical Sciences at Suffolk County Community College in Long Island, New York.
