Differentiating Between Weather And Climate

I prepared a visual aid showing how to distinguish between climate and weather, using the standard US Government approved™ definitions.

Blue is cherry picking, but red is serious science.

    That weather has caused the cancellation of the New Year’s celebration in Ottawa.

    Even though the map shows red in the Yukon and Northwest Territories, It’s deep into the -20s and even -32 C in Yellowknife. The devil is in the detail. The red might be 1 deg. above average and the blue might be 10 deg. below average. All in all, Canada is bloody cold.

    Joe Bastardi has a great daily summary today. Discusses climate for most of it.

    Oh, God. When will it end?
    “[1] The current observed value of the ratio of daily record high maximum temperatures to record low minimum temperatures averaged across the U.S. is about two to one. This is because records that were declining uniformly earlier in the 20th century following a decay proportional to 1/n (n being the number of years since the beginning of record keeping) have been declining less slowly for record highs than record lows since the late 1970s. Model simulations of U.S. 20th century climate show a greater ratio of about four to one due to more uniform warming across the U.S. than in observations. Following an A1B emission scenario for the 21st century, the U.S. ratio of record high maximum to record low minimum temperatures is projected to continue to increase, with ratios of about 20 to 1 by mid-century, and roughly 50 to 1 by the end of the century.”

      Interesting if true. But considering how much fraud has gone into other data sets my money would be on a more detailed analysis showing a cyclical output.

    Tony, just on these type graphics alone you are a national treasure, and with all else you do, your worth is off the “charts”!

      Thanks Tim!

      I agree. This graphic explains things that everyone can immediately understand in seconds. Those who don’t want to understand it must have to look away to avoid such inconvenient realities – and I’m sure they do. But in the meantime I just saw retweeted on Joe Bastardi’s Twitter feed and it is absolutely perfect for such uses. Very effective!

      Also very effective is the brutal sarcastic humor!

    And Whitehorse, Yukon, in the “Red Area” is at…. Ready/ …. -27 Celsius.

    Well here it comes. Snow 3-6″ tonight. Harbinger of the clipper that is going to lead in the colder temperatures coming starting the New Year. Bone with plenty of ham left on it that was left over from Christmas has been in the pot simmering since this morning. Potatoes cut and ready. We just snapped a big mess of fresh green beans that I battled to get at the store where it was busy with people stocking up because of the snow. By 18:00 we’ll have a two gallon pot full of Ham, green beans, and potatoes. Freshly baked Sourdough rolls to go with it. Anyone that can make it is invited for dinner for good down home cooked meal.

    That New York Times blurb about climate change is as fine a piece of propaganda as I’ve seen! The late unlamented Dr Josef Goebbels would been most approving. Black equals white; a circle is really a square – scientists say ……
