Well, we’re on our victory lap, so, of course, we start at the start. My very first post was to poke a little at a graph which was often employed by the alarmist lunatics throughout the world ……. the dreaded Spring snow cover decline!
While my first post was rough (I was just trying to figure out the posting of graphics and the like) it was the start of the end for the iconic alarmist graph. I don’t see it much, anymore. It used to be trotted out on a daily basis from one place or another. Here’s the latest rendition.
Now, most would know by now the several problems with this graph. In all humility, I’ve got to say we were probably a large part of the reason why many know to point these things out, now. When I started posting on the snow cover, there weren’t a lot of skeptic sites doing so.
The first problem with the graph is the act of deception by arbitrary base of the y-axis. The actual snow cover runs from a little more than 27 mil sq. km to a little less than 34 mil sq. km. And, yet, they use 26 million as their base, thus giving the trend line the extreme slope.
Another huge problem with the graph is the time line. Rutgers is pretending the numbers on the left were the same type of numbers on the right of the graph. They most certainly are not. Read here for the many alterations and inconsistencies between the values represented as the same.
So, let’s correct some of that mess. First, we put our base at zero. When using a trend line, this will give us a more realistic appreciation of the slope. Secondly, let’s eliminate some of the older values and go back 30 years. This will give us enough time to see if there is an alarming trend or not, all the while making the values more consistent with each other, although different methodologies were employed even in the 30 year graph.
I didn’t want to expend too much time and energy on this so I’m only going to graph the average of the monthly values of March through May. So, it’s not the same/same but, should be reasonably close to tell us if we’ll have snow in the spring or if we should expect it to be all melted over the next decade or so.
Well, I’m just crapping all over myself about the horrid decline in our spring snow cover! You, too? Lop off 1986 and 1987 and we’ve a nearly zero trend in our trend line.
And so it is, and so it was with our dishonest alarmist friends. The snow cover isn’t decreasing during spring, they’re interpreting the snow cover differently than they were in the past. I’d call them a bunch of idiots if I didn’t know most were purposefully trying to deceive people.
