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 group of friends to the beach and position them 50 metres apart. When a wave lands, each person notes whether it reached further than the previous waves. If it does, that person shouts out , "a record!". So at first everyone is shouting out 'a record' very frequently—because the sample is so small. However, after 30 seconds or so the frequency will drop. Then after a few minutes the frequency of shouts will either noticeably decrease until they stop altogether (the tide is going out), or they will settle into a steady rhythm (the tide is coming in). Note that the more friends you take with you, the faster you'll arrive at an answer.

When in doubt, ask... your insurance company!

“The prospect of extreme climate change and its potentially devastating economic and social consequences are of great concern to the insurance industry.” — Kyoto Statement of The Geneva Association, 29th May, 2009

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.

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.

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.

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 is like CNN.  Climate is like the History Channel.

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.

Think 'We'll adapt'?  Our infrastructure may not be able to adapt

Our very elaborate infrastructure won't work because it was designed for the climate we had, not the one we are going to have. — Dr. Richard Somerville, Distinguished Professor, Climate Research Division at Scripps Institution of Oceanography.

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.


Slow down, you'll have an accident!

Living with increased CO2 in the atmosphere is like a rain shower on the highway. It doesn't necessarily cause a crash but it increases the possibility of one and is likely to make any accident more severe.

Reject climate change? That harms your beach house & your kids

'If you dismiss all climate science as a hoax, I can’t help you. That’s between you & your beach house — and your kids, whose future you’re imperiling.' —Thomas Friedman, NY Times columnist.

Recent floods: Not just power of nature, but power of man

"(Recent floods) not just by the power of nature but by the power of man." — climate activist Bill McKibben
